Technical Field

The invention relates to the field of medical instruments, in particular to vertebral plate rongeur.

Background

The vertebral plate rongeur is the most common and very important surgical instrument for spinal surgery, the existing rongeur is fixed together by two half bodies through connecting pieces such as screws, a movable tong head cannot be detached, dead angles which are difficult to clean easily exist at the screw hole position and the connecting part of the two half bodies when the rongeur is cleaned, and the rongeur is not easy to be completely cleaned. The forceps head is fixed together by two half bodies through a connecting piece such as a screw, the forceps head can only be in a linear shape, and a fixed forceps head and a movable forceps head with radian and camber can not be produced according to the angle requirement of an operation part, so that the reliability and the accuracy in the operation use process are influenced.

Disclosure of Invention

The invention aims to overcome the defects in the prior art and provide a vertebral plate rongeur.

The purpose of the invention is achieved by the following technical scheme: the vertebral plate rongeur mainly comprises a fixed tong head, a movable tong head, steering knuckles, push rods, inner push rods, tong rods, a front handle, a rear handle, rivets and inner chutes, wherein the inner chutes are arranged on two sides of the fixed tong head, the movable tong head, the plurality of steering knuckles and the push rods at the rear end are clamped and connected in series and then are installed in the inner chutes on the left side and the right side of the fixed tong head, the rear end of each push rod is butted with the corresponding tong rod, the tong rods are inserted into the inner push rods, the front ends of the inner push rods are connected with the fixed tong head, the rear ends of the inner push rods are connected with the rear handle, the rear ends of the tong rods extend into the rear handle and are connected with the front handle, and the.

The movable tong head, the push rod and the plurality of steering knuckle clamps are connected in series and then are installed in the inner chutes on the left side and the right side of the fixed tong head, and the movable tong head, the push rod and the plurality of steering knuckle clamps are connected in a rivet-free structure.

The clamp head of the fixed clamp head is large outside and small inside.

The push rod is tubular.

The fixed binding clip has a certain radian suitable for actual use.

The invention has the beneficial effects that: the invention can be produced and manufactured by randomly adjusting the radian, the angle and the bending degree of the fixed forceps head according to the actual operation requirements of doctors during production, and the production is convenient; when the bone occlusion is carried out, the operation is simple and convenient, the occlusion and cutting force is high, and the occluded and cut broken bones are not easy to block; the movable tong head is more thoroughly disassembled and cleaned, and time and labor are saved.
