Referring to fig. 1-8, the anti-blocking closed flushing drainage tube for treating deep infection of the spine of the present invention comprises an outer tube 1 and an inner tube 2 capable of relatively rotating in the outer tube 1, wherein a crease 3 is arranged on the tube wall of the outer tube 1, first arc protrusions 4 are arranged at the upper and lower ends of the inner wall of the outer tube 1, second arc protrusions 5 are arranged at positions corresponding to the two first arc protrusions 4 on the outer wall of the inner tube 2, a clamping sleeve 6 is integrally arranged on the outer wall of the outer tube 1, a first bearing 7 is embedded in the outer tube 1, the inner tube 2 is arranged in an inner sleeve of the first bearing 7 in a penetrating manner, a knob 8 is integrally arranged on the inner tube 2 at one side close to the first bearing 7, a second bearing 9 is arranged at one end of the inner tube 2 far away from the first bearing 7, a drainage tube 10 is sleeved on the outer sleeve of the second bearing 9, a drainage bag 11 is connected at one end of the drainage tube 10 far away from the second bearing 9, and a plurality of inwards concave clamping grooves 13 are integrally arranged on the outer tube 1 close to the clamping sleeve 6. In the present invention, the function of the ferrule 6 is to prevent the outer cannula 1 from slipping out of the body, and also to prevent leakage of drainage fluid.
In order to enable the outer sleeve 1 of the present invention to be used without leakage of drainage liquid and without drainage failure caused by leakage of air, the outer sleeve 1 of the present invention is divided into an upper outer sleeve 101 and a lower outer sleeve 102 by the crease slits 3, and the crease slits 3 are arranged in a corrugated shape, and in the present invention, the crease slits 3 do not penetrate the whole outer sleeve 1, but only about one third of the total length of the outer sleeve 1, like the stacking of the commonly used corrugated pipe structure, mainly plays a role in that when the second arc-shaped protrusion 5 abuts against the first arc-shaped protrusion, it can be spread, thereby increasing the diameter of the outer sleeve 1, so that the blocking object can be dredged under the condition that the inner sleeve 2 rotates when the outer sleeve 1 is blocked, so as to solve the blocking situation of the outer sleeve 1.
In order to avoid the situation that a gap exists after the first bearing 7 and the second bearing 9 are installed, if a gap or a clearance exists, the overall drainage effect of the invention is affected, so that the drainage efficiency is low, even drainage failure is caused, and the like, at this time, in order to solve the problem, the first bearing 7 is internally matched with the first bearing sealing ring 71, the second bearing 9 is internally matched with the second bearing sealing ring 91, and the problems of low efficiency and even drainage failure caused by the gap of the bearings are well solved through the first bearing sealing ring 71 and the second bearing sealing ring 91 which are arranged.
In order to avoid the problem that the outer sleeve of the invention falls off or the drainage liquid permeates after the operation is inserted and installed, the outer wall of the outer sleeve 1 is integrally provided with the clamping sleeve 6, and the clamping sleeve 6 is in a horn-shaped structure, so that the outer sleeve 1 can be prevented from falling off from a human body, and the problem that the drainage port of the outer sleeve is easy to leak can be solved.
In order to save cost and make the structure of the invention light and suitable, the first bearing 7 and the second bearing 9 used are plastic rolling bearings.
In order to enable the outer sleeve 1 of the present invention to be supported while the second arc-shaped protrusion 5 supports the first arc-shaped protrusion, the outer sleeve 1 should be made of an elastic material, and in order to secure the safety of the elastic material used, the elastic material used is medical silicone.
In order to make the knob 8 possibly slip during operation when rotating, a plurality of anti-slip threads 12 are integrally arranged on the surface of the knob 8, thereby solving the problem that slip phenomenon occurs during operation.
As shown in fig. 4, when the outer sleeve 1 is blocked, and the drainage liquid cannot flow out, the knob 8 can be manually rotated, and the inner tube 2 installed in the first bearing 7 is driven to rotate by the knob 8, so that the second arc-shaped protrusion 5 integrally arranged on the outer wall of the inner tube is driven to rotate, and the outer sleeve 1 is provided with the crease 3 and is in a stacked arrangement (as shown in fig. 5), is made of an elastic material and is made of medical silica gel, so that the outer sleeve 1 can continuously and repeatedly move in an opening and closing manner under the action of the second arc-shaped protrusion 5, and blood clots or other sundries blocked in the outer sleeve 1 can be scattered or fall off under the condition that the outer sleeve 1 can continuously and repeatedly move in an opening and closing manner, so that the problem of blocking of a drainage tube is solved.
As shown in fig. 6, when the crease seam 3 is unfolded, the contact area between the outer sleeve 1 and the drainage part is enlarged, and then the inner tube 2 is continuously rotated, so that the inner tube can be continuously opened and closed (namely, when the first arc-shaped bulge and the second arc-shaped bulge are mutually jacked, the first arc-shaped bulge and the second arc-shaped bulge are unfolded, and when the first arc-shaped bulge and the second arc-shaped bulge are staggered, the first arc-shaped bulge and the second arc-shaped bulge are unfolded, and the second arc-shaped bulge and the drainage part are unfolded, so that the purpose of the invention is achieved.
In order to improve drainage efficiency, a plurality of outer drainage holes which are beneficial to drainage are formed in the outer sleeve 1. In order to drain the solution or other objects entering the inner part of the outer sleeve 1, a plurality of inner drainage holes are formed in the inner tube 2, and the aperture of each inner drainage hole is larger than that of each outer drainage hole. The aperture of the inner drainage hole is larger than that of the outer drainage hole, so that other objects in the badge of the solution entering the outer sleeve 1 can be drained outside the body.
As shown in fig. 9, in order to facilitate the fixation of the outer sleeve 1 of the present invention, a clamping groove 13 recessed toward the inner side of the outer sleeve 1 is provided at one side close to the ferrule 6, and the clamping groove 13 is mainly used for surrounding the clamping groove 13 with a medical suture after the outer sleeve 1 is mounted, and then suturing the suture on the skin of a human body, thereby further achieving the purpose of preventing the falling-off thereof.
When the method is used, one end of the outer sleeve 1 is inserted into a place where drainage is needed, the inner tube 2 provided with the first bearing 7 is installed in the outer sleeve 1 in a penetrating way from inside to outside, the first bearing sealing ring 71 is installed on the first bearing 7, after the installation is finished, a wound is sewed, when the wound is sewed, the clamping sleeve 6 is arranged in a human body, then the outer sleeve 1 is wound by a wire, the wound wire is arranged in the clamping groove 13, the wound is sewed, the wound can be sewed, the outer sleeve 1 can be fixed, after the installation is finished, the second bearing 9 is installed in the inner tube 2, the second bearing sealing ring 91 is installed, and then the drainage tube 10 is penetrated into the second bearing 9, so that the installation of a pipeline is finished. When the inner tube 2 is removed, the inner tube 2 is taken out of the outer sleeve 1, the suture wound on the outer sleeve 1 is cut off by scissors, the outer sleeve 1 at the suture position is extruded by hands, and then the outer sleeve 1 is pulled out.
Specifically, the outer sleeve is matched with the inner tube which can rotate in the outer sleeve, when the outer sleeve is blocked, the inner tube is rotated, the second arc-shaped bulge integrally arranged on the outer wall of the inner tube props against the first arc-shaped bulge arranged on the inner part of the outer sleeve, so that the upper outer sleeve and the lower outer sleeve are supported, the space of the outer sleeve is increased, the problem that the existing flushing drainage tube is easy to block is solved, the drainage tube does not need to be rotated after the blockage occurs, the insertion depth and direction are not required to be repeatedly adjusted, the drainage can be recovered normally only by rotating the inner tube, the occurrence of the blockage event of the drainage tube can be reduced, the exogenous infection caused by repeatedly adjusting the drainage tube is reduced, and the pain brought to a patient in the treatment process is reduced.
