Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments, in particular to a surgical threading hook for neuropathic pain. Background Art

[0002] A surgical threading hook is a commonly used instrument in surgery, used to thread, ligate blood vessels or tissues, and cut the thread ends when necessary. It usually consists of a handle and a tip with a specific shape. The handle is designed to be easy for doctors to hold and manipulate, while the tip is usually sharp enough to perform precise puncture and ligation operations during surgery.

[0003] Currently, the commonly used surgical threading hooks in medicine usually use sutures pushed by fingers. During the operation, the doctor wears surgical gloves. Because the doctor wears gloves and the surface of the gloves may have disinfectant alcohol, the fingers are prone to slipping when pushing the sutures, which may cause the sutures to fail to accurately pass through tissues or organs, increasing the difficulty and risk of the operation. In addition, pushing the sutures with fingers may lead to inaccurate operation, especially when fine suturing is required or in local narrow areas. It may be difficult for the doctor to control the movement of the threading hook, resulting in inaccurate or unsatisfactory puncture position of the suture. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a surgical threading hook for neuropathic pain, which solves the problem that when a doctor wears gloves and the surface of the gloves may have disinfectant alcohol, the fingers may slip when pushing the suture, which may cause the suture to fail to pass through the tissue or organ accurately, thereby increasing the difficulty and risk of the operation.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-2 In this embodiment, a surgical threading hook for neuropathic pain is used to push the suture from the inside of the handle 1 to the curved hook 3 to increase the stability of the suture when it is pushed.

[0024] Specifically, it includes a handle 1, a threading needle 2 and a curved hook 3; the threading needle 2 is arranged at the front section of the handle 1, and the curved hook 3 is assembled at the end of the threading needle 2 away from the handle 1, and the handle 1, the threading needle 2 and the curved hook 3 are all provided with threading channels 4 that are interconnected; a wire feeding groove 5 is vertically provided inside the handle 1, and a wire feeding structure 6 is provided inside the wire feeding groove 5 for pushing the suture thread to move along the threading channel 4.

[0025] During actual use, the suture thread is first inserted from the threading channel 4 inside the handle 1 and extended to the inside of the wire feeding groove 5, and the suture thread is pushed to the inside of another section of the threading channel 4 inside the handle 1 through the wire feeding structure 6 inside the wire feeding groove 5, and the suture thread is transmitted to the inside of the threading needle 2 and the curved hook 3 through the threading channel 4 on the front side of the handle 1, and extends out from the inside of the curved hook 3, thereby completing the pushing of the suture thread.

[0026] See also Figure 2-3 In order to push the suture thread, the wire feeding structure 6 in this embodiment includes at least two support seats 601, and at least two support seats 601 are vertically assembled on the inner bottom wall of the wire feeding groove 5. A rotating shaft 602 is rotatably connected between the opposite sides of at least two support seats 601, and a pushing roller 603 is sleeved on the outer side of the rotating shaft 602 so that the pushing roller 603 can rotate on the ZX plane; an extrusion ring 604 is sleeved on the outer side of the pushing roller 603, and the extrusion ring 604 is attached to the inner bottom wall of the wire feeding groove 5.

[0027] During actual use, hold the handle 1, use the thumb to rotate the squeezing ring 604 to drive the push roller 603 to rotate, and the rotating shaft 602 located inside the push roller 603 rotates accordingly, that is, when the push roller 603 rotates clockwise, the suture thread can be pushed toward the direction of the threading needle 2, otherwise it moves toward the end of the handle 1, thereby pushing the suture thread.

[0028] That is, the user can accurately control the pushing direction and speed of the suture by rotating the squeezing ring 604, thereby achieving precise operation of the suture. Moreover, the operation of this structure is relatively simple, and only one finger is needed to control the pushing of the suture, which improves the convenience and flexibility of operation.

[0029] Furthermore, in order to facilitate the rotation of the push roller 603 and the extrusion ring 604, the front and rear sides of the inner wall of the wire feeding groove 5 in this embodiment are preferably arranged in an inclined shape.

[0030] In addition, in order to ensure the stable transmission of the suture thread, the wire feeding groove 5 is set in the middle section of the threading channel 4 inside the handle 1 to divide the threading channel 4 inside the handle 1 into two sections, and an arc-shaped groove is opened on the inner bottom wall of the wire feeding groove 5, and the arc-shaped groove is connected to the two sections of the threading channel 4 in the handle 1.

[0031] In the actual process, the suture thread is first inserted from the threading channel 4 at the end of the handle 1, and extends to the inside of the wire feeding groove 5, and moves along the extension direction of the arc groove. When one end of the suture thread moves to the bottom of the push roller 603 and the extrusion ring 604, the extrusion ring 604 can be rotated to continue to push the suture thread to move, so that one end of the suture thread extends to the inside of the front threading channel 4.

[0032] Furthermore, in order to ensure the friction between the suture thread, the extrusion ring 604 is preferably a rubber ring in this embodiment.

[0033] In actual setting, the extrusion ring 604 is in an extruded state after contacting the inner bottom wall of the wire feeding groove 5. Secondly, the extrusion ring 604 fits tightly inside the wire feeding groove 5 and the arc groove to ensure that the extrusion ring 604 can effectively push the suture thread to move when rotating.

[0034] Further preferably, in order to facilitate the extension of the suture thread into the interior of the handle 1, a conical groove is opened in the front section of the handle 1, and the conical groove is connected to the threading channel 4 inside the handle 1, and at least two anti-slip grooves are distributed in a circular array on the outside of the handle 1.

[0035] In actual settings, the design of the conical groove can effectively increase the input end of the threading channel 4, increasing the convenience of threading. In addition, by providing an anti-slip groove on the outside of the handle 1, the stability of the handle 1 when holding it can be effectively increased.

[0036] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
