Description
Technical Field
The invention relates to the field of medical instruments, in particular to an operating handle and a medical adjustable bent sheath tube.
Background
At present, an interventional operation usually needs to establish a channel between a diseased part in a patient and an external operation end by means of an interventional diagnosis and treatment sheath (such as a guiding sheath, a conveying sheath, a guiding catheter and the like) so as to introduce various diagnosis and treatment instruments, medicines, implantation instruments and the like to the diseased part of the patient, and achieve the purpose of avoiding surgical operation and reaching the diseased part. Intervene type and diagnose sheath pipe and generally comprise sheath pipe body and the operating handle who installs this sheath pipe body, and the sheath pipe body is longer and have the inner chamber as the passageway, and the sheath pipe body has distal end and near-end, and the distal end can conveniently get into human lumen (like the blood vessel), and the near-end then is used for connecting operating handle and supplies professional medical personnel to use. In the interventional operation, medical personnel need to send the distal end of the sheath catheter body to a preset position through the external operation on the operating handle under the guidance of an X-ray machine.
In order to adapt the distal end of the sheath tube body to the anatomical shape of a specific lesion site, people pre-mold the distal end of the sheath tube body into different curved shapes according to different sheath tube applications, however, even if the distal end pre-molded interventional diagnosis sheath tube with various shapes and angles is developed, the following situations frequently occur in clinical use: the distal end pre-molded sheath tubes with various shapes and angles can not be adapted to individual physiological anatomical structures one by one, when the problems occur in the operation, a doctor usually withdraws the sheath tube and selects the pre-molded sheath tubes with other shapes again, so that the operation consumption is improved, the cost born by a patient is increased, the probability that the lumen cavity tissues of the patient are damaged is increased, the operation time is prolonged, and the radiation time of the patient is prolonged. Distal end pre-shaping interventional diagnostic sheath tubes of various shapes and angles are put into clinical use. This requires the hospital to have to stock all the shapes and specifications of the sheaths, which will undoubtedly increase the stock size and quantity of the hospital and increase the cost of the hospital. Based on the above situation, in recent years, a sheath distal end adjustable bending technology has been developed, which applies a medical adjustable bending sheath and repeatedly changes the distal end of the sheath body at different angles by an in vitro adjustment operation so as to adapt to different physiological anatomical forms.
The medical adjustable bent sheath catheter in the prior art comprises an operating handle, a sheath catheter body arranged on the operating handle and a bending adjusting wire; the operation handle is a forked type and comprises a main support and a side support, the far end of the bending adjusting wire is connected with the far end of the sheath tube body, the near end of the bending adjusting wire penetrates through the side support of the handle after penetrating out of the side wall of the sheath tube body close to the near end and is connected with a lock control sliding block arranged on the side support of the handle, the bending adjusting wire is pulled or loosened through the lock control sliding block to change the bending shape of the far end adjustable bending section of the sheath tube body, and the lock control sliding block must be controlled by hands. Because the main tributary of forked type handle does not provide the position of holding, and main tributary and side branch overall dimension are thinner and shorter simultaneously, are not suitable for the operation of holding, and during the use, medical personnel need to hold adjustable curved sheath pipe handle and exert certain thrust, and the main tributary is held to one hand, and the control slider is controlled to the other hand, and it is very inconvenient to use.
In addition, in the medical adjustable bent sheath tube in the prior art, an exhaust assembly is generally installed inside the operating handle, the exhaust assembly comprises an exhaust member, the exhaust member is provided with an exhaust cavity, the proximal end of the sheath tube body is communicated with the distal end of the exhaust cavity, and a hemostatic valve cover for closing the proximal end of the exhaust cavity is installed on the proximal end of the exhaust cavity; in the use process, liquid needs to be supplied to the exhaust cavity, the far end of the sheath tube body is sent to the preset position after air in the sheath tube body is flushed and exhausted, and therefore the fact that no gas exists in the part of the sheath tube body entering the human body is guaranteed, and the smooth operation is guaranteed. However, in the prior art, the hemostatic valve cover is not easy to install, and the hemostatic valve cover is easy to slide relative to the exhaust member after being installed on the proximal end of the exhaust cavity, so that the hemostatic valve cover is loosened or falls off.
In conclusion, the medical adjustable bent sheath tube in the prior art has the problems that the bending is inconvenient, the hemostatic valve cover at the installation position of the exhaust assembly is not easy to install, and the hemostatic valve cover is easy to rotate relative to the exhaust piece after being installed on the near end of the exhaust cavity, so that the hemostatic valve cover is loosened or falls off and the like.
