When bipolar is used, excessive water flow will affect the effect of hemostasis and ablation. , water flowing through the teenager will cause excessive side damage. With the popularization of precise minimally invasive surgery, a bipolar product with adjustable water volume and power is urgently needed.

SUMMARY OF THE INVENTION

The purpose of the present invention is to provide an intraoperative hemostasis device in view of the deficiencies in the prior art.

For achieving the above object, the present invention adopts the following scheme:

An intraoperative hemostasis device, characterized in that: the intraoperative hemostasis device comprises a forceps handle, a wiring plug, a drip tube, a pipe hook, and a wiring plug; the forceps handle is fixedly connected with a plug connector, and the forceps handle is a hollow structure and The tweezers handle is provided with a hollow structure, the drip tube passes through the hollow structure, the tube hook is fixedly connected with the tweezers handle or integrally formed with the tweezers handle, the tube hook is connected to the hollow structure of the opposite side of the tweezers handle and can be connected with the tweezers handle, and the tube hook is connected with the tweezers handle. When the opposite tweezer handle is connected, the tweezer handle is in a pinched state, and the tweezer handle is in a natural state when the tube hook is separated from the opposite tweezer handle. In the pinching state, the drip tube is in a passage state, and when the tweezer handle is in a natural state, the pipe hook can pull the drip tube out of the hollow structure of the tweezer handle to form a closed state.

Further, the hollow structure is replaced with a blind hole structure.

Further, the drip tube is arranged in the hollow structure of the forceps handle.

Further, the tail of the forceps handle is fixedly connected with the plug connector.

Further, the wiring plug is connected with the water receiving pipe head, and the drip pipe is communicated with the water receiving pipe head.

Further, the number of tweezers handles is 2, the number of tube hooks is 2, the 2 tube hooks are slidingly connected to each other, and the 2 tube hooks have a limiting effect on the 2 tweezers handles.

Further, the two tube hooks can not only limit the forceps handle when the forceps handle is kneaded, but also limit the forceps handle when the angle between the forceps handle becomes larger.

Further, a stabilization sleeve and a stabilization column are arranged between the two forceps handles, and when the two forceps handles are kneaded, the stabilization column slides in the stabilization sleeve.

Further, the rear end of the water receiving pipe head is connected to the precision infusion set and the dripping water controller in sequence.

Further, the way in which the tube hook is connected with the opposite side forceps handle is as follows: the tube hook is inserted into the hollow structure of the opposite side forceps handle, the hook head of the tube hook and the hollow structure are connected in a sliding fit, and the hook head of the tube hook can be free at the hollow structure. in and out.

Further, the way in which the tube hook is connected with the opposite side forceps handle is as follows: the tube hook is inserted into the hollow structure of the opposite side forceps handle, the hollow structure causes the tube hook to be deformed under pressure, and the tube hook is connected to the hollow under the action of the elastic force generated by the pressure deformation. A relatively static state is formed between the inner surfaces of the structure through friction;

Further, the manner in which the tube hook is connected with the opposite side forceps handle is as follows: the outer surface of the hook head of the tube hook has a tooth-like structure, the inner surface of the hollow structure of the forceps handle has a corresponding tooth-like structure, and the tube hook is inserted into the opposite side forceps handle. At the hollow structure, the tooth-like structures mesh with each other, the hook head of the pipe hook is deformed by the thrust of the tooth-like structure during the insertion process, and the tooth-like structure moves relatively along the meshing surface to adjust the insertion distance of the hook head of the pipe hook. After the structure is engaged, when the tweezers handle is separated in the direction of the tube hook, the toothed structure on the outer surface of the hook head of the tube hook and the toothed structure on the inner surface of the hollow structure of the tweezers handle form a stop surface to prevent the hook head of the tube hook from passing from the hollow structure of the tweezers handle. Separation, when it is necessary to separate the tube hook from the hollow structure of the tweezers handle, apply force to the hook head of the tube hook in the direction perpendicular to the hook handle of the tube hook to make the toothed structure on the outer surface of the hook head of the tube hook and the inner surface of the hollow structure.

1. The pinching and opening state of the tweezers handle can be controlled by cooperating with the pipe hook, the drip tube and the tweezer handle, and the control of the open and closed state of the drip tube can be realized at the same time. The pipe hook can be connected with the hollow structure of the opposite tweezer handle The kneading of the tweezer handle can be realized and the kneading state can be guaranteed to be stable and continuous, not easy to loosen, and can maintain a high durable state.

2. The drip tube is arranged in the hollow structure to maintain the integrity of the hemostatic device and reduce the interference of the exposed drip tube on the surgical process. At the same time, the drip tube penetrates through the hollow structure and passes through the hollow structure, and cleverly hooks the tube to the tweezers handle. The control is combined with the control of the pipe hook on the open and closed state of the drip pipe. When the pipe hook is connected with the opposite tweezer handle, the pipe hook does not have a traction effect on the drip pipe and forms a passage, and the water in the drip pipe can flow out freely. When the pipe hook is separated from the opposite tweezer handle, the pipe hook can pull out the drip tube, so that the drip tube is bent at the hollow structure, and the water flow cannot pass through. The kneading device and the drip tube control device need to be operated separately, which increases the operating time and cost. The drip tube control device in the present invention can sensitively control the opening and closing of the drip tube and control the kneading state of the tweezer handle. On the basis of ensuring the function of the tweezer handle Reduced control complexity.

3. There is a sliding connection between the tube hooks and the tube hook has a limiting effect on the tweezers handle. In addition to controlling the pinching state of the tweezers handle and controlling the opening and closing state of the drip tube, the tube hook can also limit the position of the tweezers handle. The set protrusion passes through the track set in the opposite side tube hook and forms a track limit block at the end, which can not only ensure the protrusion slides along the track, but also limit the longitudinal movement distance of the protrusion, ensure that the protrusion does not leave the track, and improve the stability of the tweezer handle. The performance and precision of operation will not cause the misalignment of the forceps handle during the operation; when the tube hook is connected with the hollow structure of the opposite forceps handle, the tube hook is plugged in the hollow structure, and the tube hook is under the rebound effect of the tube hook itself. In the scheme of forming an interference fit with the hollow structure, the kneading state can be ensured, and the protrusion on the tube hook can limit the minimum distance between the tweezers in the pinch state, and the hook head of the tube hook can pass the hook head of the tube hook when the tweezers are separated. The stop parts at the tweezers abut against each other to limit the maximum distance between the tweezers.

4. The stabilization column and the stabilization sleeve ensure that the tweezers handle is accurately and correctly positioned when kneading, and the precise kneading of the tweezers handle tip is ensured under the premise of the basic guide of the tube hook.

5. The scheme of connecting the hook head of the tube hook and the hollow structure of the opposite tweezer handle with a surface tooth structure can realize the precise adjustment of the distance between the hook head of the tube hook and the hollow structure of the opposite tweezer handle, and the tooth structure is matched with the hook of the tube hook. When the head is inserted into the hollow structure of the contralateral forceps handle, the relative movement of the teeth can provide a clear "frustration" feeling, which is convenient for the doctor to grasp the degree of pinching of the forceps handle. Stable working state, when the tweezers handle needs to be opened, it is only necessary to apply force to the hook head of the hook in the direction of the hook of the hook. The hook head of the tube hook is taken out from the hollow structure of the opposite tweezer handle, the operation is simple, the precision is high, and the stability is good.

6. The hook head of the pipe hook and the hollow structure of the opposite side of the tweezers handle are connected with a sliding fit that can freely enter and exit, which is convenient for the operator to flexibly control the degree of pinching of the tweezers handle, and facilitate the control of the water flow of the drip tube. When the hook head of the pipe hook and the hollow structure of the opposite tweezers handle are connected by friction to form a relatively static state, it can provide the operator with a temporary kneading state, provide a variable kneading force, and can reflect the kneading situation in real time.

7. The hollow structure on the tweezers handle is replaced by an alternative to the blind hole structure, which can further increase the limiting effect of the tweezers handle and further avoid excessive pinching of the tweezers handle.

Detailed ways

As shown in FIG. 1 , an intraoperative hemostasis device of the present invention includes: two forceps handles 1 , wiring plugs 2 , two drip tubes 3 , and two tube hooks 5 ; the tube hook includes a tube hook hook handle 11 and the hook head 10 of the pipe hook; the tweezer handle 1 is fixedly connected with the plug connector 2, the tweezer handle 1 is a hollow structure and the tweezer handle is provided with a hollow structure, and the drip tube 3 is arranged in the hollow structure of the tweezer handle and passes through the hollow structure , the tube hook 5 and the tweezers handle 1 are integrally formed, and the tube hook can be connected with the tweezers handle at the hollow structure of the opposite tweezers handle. When the tweezer handle 1 is separated from the opposite side tweezer handle 1, the tweezer handle 1 is in a natural state, and the pipe hook 5 can be connected with the drip tube 3 at the hollow structure of the opposite side tweezer handle 1. When the tweezer handle 1 is in a fully pinched state, the drip tube 3 is in the channel state. , when the forceps handle 1 is in a natural state, the pipe hook 5 can pull the drip tube 3 out of the hollow structure of the forceps handle 1 to form a closed state. The tail of the tweezer handle is fixedly connected with the plug connector 2 . The wiring plug 2 is connected with the water receiving pipe head 4, the drip pipe 3 is connected with the water receiving pipe head 4, and the rear end of the water receiving pipe head 4 is connected to the precision infusion set 7 and the dripping water controller 8 in turn; Column 10, when the two tweezer handles 1 are squeezed together, the stabilizing column 9 slides in the stabilizing sleeve 10.

As shown in Figure 2, the two pipe hooks 5 are slidingly connected to each other. The two pipe hooks 5 can not only limit the position of the forceps handle 1 when the forceps handle 1 is kneaded, but also can adjust the position of the forceps handle 1 when the angle between the forceps handle 1 becomes larger. Tweezers handle 1 limit. The outer surface of the hook head 10 of the tube hook has a tooth-like structure, and the inner surface of the hollow structure of the forceps handle 1 has a corresponding tooth-like structure. When the tube hook 5 is inserted into the hollow structure of the opposite forceps handle 1, the tooth-like structures mesh with each other. The hook head 10 is deformed by the thrust of the toothed structure during the insertion process, and the toothed structure moves relatively along the meshing surface to adjust the insertion distance of the hook head 10 of the pipe hook. When the toothed structure is engaged, it separates along the direction of the pipe hook 5 When the tweezer handle is 1, the toothed structure on the outer surface of the hook head 10 of the tube hook and the toothed structure on the inner surface of the hollow structure of the tweezer handle form a stop surface, so as to avoid the separation of the hook head 10 of the tube hook from the hollow structure of the tweezer handle. When the hook 5 is separated from the hollow structure of the tweezer handle, applying force to the hook head 10 of the pipe hook in the direction perpendicular to the hook handle 11 of the pipe hook can make the toothed structure on the outer surface of the hook head 10 of the pipe hook and the toothed structure on the inner surface of the hollow structure. When the structure is separated, the hook head 10 of the pipe hook can be separated from the hollow structure without being blocked.

A stopper portion is formed at the hook head 10 of the tube hook, and the hook head 10 of the tube hook and the hook head 10 of the opposite side tube abut against each other through the stopper portion to limit the maximum distance between the tweezers 1 . A protrusion 14 is formed on the outer surface of the hook head 10 of the pipe hook along the direction perpendicular to the hook handle 11 of the pipe hook. The hook handle 11 of the pipe hook is formed with a track 12 that cooperates with the protrusion 14. The protrusion 14 can be in the track 12 of the hook handle 11 of the opposite side. Sliding longitudinally along the hook handle 11 of the tube hook, the protrusion 14 limits the hook head 10 of the tube hook on the track 12 near the end of the forceps handle 1, and limits the distance that the hook head 10 of the tube hook is inserted into the hollow structure of the opposite side forceps handle. The end of the protrusion 14 forms a rail limit block 15 to limit the distance that the protrusion 14 moves along the direction perpendicular to the hook handle 11 of the pipe hook.

The working principle of the intraoperative hemostasis device of the present invention is as follows: in a natural state, the two tube hooks 5 pull the drip tube 3 out of the hollow structure of the opposite side forceps handle 1, so that the drip tube 3 is bent at the hollow structure, and the water flows. If it cannot pass through, the water flow in the drip tube 3 can be controlled; when the tweezers handle needs to be pinched, the operator uses two fingers to squeeze the tweezers handle 1 near the hollow structure of the two tweezers handles, and the hook head 10 of the pipe hook enters under the action of thrust At the hollow structure of the opposite side tweezer handle, during the mutual sliding of the two pipe hooks 5, the protrusion 14 slides longitudinally along the pipe hook hook handle 11 in the track 12 of the opposite side pipe hook hook handle 11, which guides the sliding of the pipe hook. The protrusion 14 acts as a limiter on the hook handle 1 at the end of the track 12 near the tweezers handle 1, limiting the distance that the hook head 10 of the pipe hook is inserted into the hollow structure of the opposite side of the tweezers handle, and the track limit block 15 restricts the protrusion 14 along the vertical direction of the pipe hook hook. The distance that the handle 11 moves in the direction to ensure that the tweezers handle is properly kneaded. When the hook head 10 of the tube hook enters the hollow structure of the opposite tweezer handle, the toothed structure on the outer surface of the hook head 10 of the tube hook and the inner surface of the hollow structure of the opposite tweezer handle The tooth-like structure is engaged. According to the need of the kneading distance, the operator can choose the distance at which the hook head 10 of the pipe hook is inserted into the hollow structure of the opposite tweezer handle. Gradually reset, the drip tube 3 forms a passage, and the water flow can pass. When the tweezer handle 1 needs to be separated, the operator squeezes the track limit block 15 on the hook handle 11 of the pipe hook with two fingers, so that the toothed structure on the outer surface of the hook head 10 of the pipe hook and the toothed structure on the inner surface of the hollow structure of the tweezer handle When the structure is separated, the hook head 10 of the tube hook can be taken out from the hollow structure of the opposite side of the tweezer handle, and the two tweezer handles are opened, and the water flow in the drip tube 3 cannot pass through. During the separation process of the tweezer handle 1, the hook head 10 of the tube hook The hook head 10 of the opposite side tube hook is in contact with each other through the stop part, which limits the maximum distance between the forceps handle 1 and avoids damage to the device. During kneading, the stabilizing column 9 slides in the stabilizing sleeve 10 to play a guiding role, which can improve the kneading accuracy of the tweezers handle. During the operation, the operator can control the precision infusion set 7 and the drip controller 8 to achieve fine control of the water flow, and realize the power-on operation through the plug-in connector 2 .

When the pipe hook 5 is connected with the opposite side forceps handle 1, the pipe hook is inserted into the hollow structure of the opposite side forceps handle 1, the pipe hook hook head 10 and the hollow structure are connected in a sliding fit, and the pipe hook hook head 10 can be inserted in the hollow structure. In the scheme of free entry and exit of the structure, the operator can realize the matching connection between the pipe groove hook 10 and the hollow structure by pinching the tweezer handle with two fingers, and releasing the two fingers can realize the pipe hook hook 10 from the hollow structure. The operator can freely control the pinching state of the tweezers handle and the opening and closing state of the drip tube according to the needs of the separation operation.

When the tube hook 5 is connected with the opposite side forceps handle 1, the tube hook 5 is inserted into the hollow structure of the opposite side forceps handle 1, the hollow structure causes the tube hook 5 to be deformed under pressure, and the elastic force generated by the tube hook 5 under pressure deformation Under the action of the solution to form a relatively static state through friction with the inner surface 13 of the hollow structure, the operator can realize the matching connection between the pipe groove hook 10 and the hollow structure by pinching the tweezer handle with two fingers, and according to the kneading method. The degree of insertion distance needs to be selected. After the hook head 10 of the tube hook is inserted into the hollow structure of the opposite side of the tweezers handle, a relatively static state is formed by frictional force, and the tweezers handle can temporarily maintain the pinched state. When the pinched part changes, the friction force is not enough to maintain In the static state, the hook head 10 of the pipe hook will move, reducing the pinch force and reducing the water flow of the drip tube. The operator can make adaptive adjustments according to the change in the pinch state. When the hollow structure of the handle is separated, the operator only needs to separate the tweezers handle outwards.

When the hollow structure on the tweezers handle 1 is replaced by an alternative to the blind hole structure, the blind hole structure can prevent the tube hook hook head 10 from being inserted into the hollow structure of the opposite tweezers handle from being too large, resulting in excessive pinching. On the basis of the position, the limit function is further increased to avoid the damage of the device or the loss of control of the kneading state.
