Embodiment Construction

[0034] The content of the present invention will be further described in detail below in conjunction with specific embodiments. figure 1 , image 3 It shows the structure diagram and cross-sectional view of the gun-type intervertebral foramen decompression forceps in the non-working state, which is composed of the main body of the forceps 1, the auxiliary function parts 2, the movable handle 3 and the elastic part 6, etc., wherein the above-mentioned The main body of the pliers 1 is composed of a main functional part 11 and a fixed handle 12 extending downward along its tail, both of which are integrally formed. The auxiliary function part 2 is arranged directly above the main function part 11 . A through hole is opened in the transition area between the main functional part 11 and the fixed handle 12 for the movable handle 3 to pass through. The movable handle 3 is connected with the main body of the clamp body 1 and the auxiliary function part 2 through the hinge shaft 4 t...

Abstract

The invention relates to a gun-type intervertebral foramen decompression forceps, which comprises a forceps body which is composed of a main functional member and a fixing handle which extends along the tail thereof, and the main functional member and the fixing handle are integrally formed; an auxiliary function member driven by a movable handle, can slide freely relative to the main function member by means of a sliding portion; a bite cutting member is disposed at the end of the auxiliary function member, and a through hole is disposed on the bite cutting member to form the bite cutting edge and a broken bone receiving cavity, correspondingly the end of the main function member is provided with a bite cutting platform adapted to the bite cutting member. In this way, the movable handle of the gun-type intervertebral foramen decompression forceps transmits the force to the bite cutting edge by means of the lever principle, which greatly reduces the grip application force. In addition,during the operation, the bone target decompression zone can be conveniently and quickly determined, and the operation efficiency is improved, and when the bone-cutting operation is completed, the broken bone receiving cavity provided on the bite cutting member can be used for timely cleaning, thereby reducing the type and number of surgical instruments.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a gun-type intervertebral foramen decompression forceps. Background technique [0002] Spinal degenerative diseases are the most common types of spinal diseases. The common types are intervertebral disc herniation, spinal canal stenosis and slippage. The above diseases may cause dura mater or nerve compression. Therefore, it is necessary to perform laminectomy and decompression Operation. Foraminal decompression forceps are mainly used in spinal surgery to expose the spinal cord by removing the lamina. The existing intervertebral foramina decompression forceps mainly have the following problems, such as poor surgical accuracy, size deviation, easy injury to the pedicle or even the nerve, and high labor intensity for bone cutting, and the operator needs to apply a large torque, which is easy to cause Hand fatigue, etc. Therefore, it is urgent for technicians to solve the abov...
