Abstract

The invention discloses a vertebral plate rongeur, which mainly comprises a fixed clamp head, a movable clamp head, steering knuckles, push rods, an inner push rod, clamp rods, a front handle, a rear handle, rivets and an inner sliding groove, wherein the two sides of the fixed clamp head are provided with the inner sliding grooves, the movable clamp head, the steering knuckles and push rod clamping positions at the rear end are connected in series and then are arranged in the inner sliding grooves at the left side and the right side of the fixed clamp head, the rear ends of the push rods are in butt joint with the clamp rods, the clamp rods are inserted into the inner push rods, the front ends of the inner push rods are connected with the fixed clamp head, the rear ends of the inner push rods are connected with the rear handle, the rear ends of the clamp rods extend into the rear handle and are connected with the front handle, and the front handle and the rear handle are movably connected by the rivets. The invention can randomly adjust the radian, angle and camber of the clamp fixing head according to the actual operation requirement of doctors during production, and has convenient production; the bone occlusion is simple and convenient to operate, the biting force is high, and the biting broken bones are not easy to be blocked; the movable clamp head is more thoroughly detached and cleaned, and time and labor are saved.

Description

Vertebral lamina rongeur

Technical Field

The invention relates to the field of medical appliances, in particular to a vertebral lamina rongeur.

Background

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

Disclosure of Invention

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

The invention aims at being completed by the following technical scheme: the vertebral plate rongeur mainly comprises a fixed clamp head, a movable clamp head, steering knuckles, push rods, inner push rods, clamp rods, front handles, rear handles, rivets and inner sliding grooves, wherein the inner sliding grooves are formed in two sides of the fixed clamp head, the plurality of steering knuckles and push rod clamping positions at the rear ends are connected in series and then are arranged in the inner sliding grooves in the left side and the right side of the fixed clamp head, the rear ends of the push rods are in butt joint with the clamp rods, the clamp rods are inserted into the inner push rods, the front ends of the inner push rods are connected with the fixed clamp head, the rear ends of the inner push rods are connected with the rear handles, the rear ends of the clamp rods extend into the rear handles and are connected with the front handles, and the front handles and the rear handles are movably connected through the rivets.

The movable clamp head, the push rod and the plurality of steering knuckle clamping positions are connected in series and then are connected into the inner sliding grooves on the left side and the right side of the fixed clamp head in a rivet-free structure.

The clamp heads of the clamp fixing heads are large at the outer sides and small at the inner sides.

The push rod is tubular.

The clamp fixing head has a certain radian suitable for practical use.

The beneficial effects of the invention are as follows: the invention can randomly adjust the radian, angle and camber of the clamp fixing head according to the actual operation requirement of doctors during production, and has convenient production; the bone occlusion is simple and convenient to operate, the biting force is high, and the biting broken bones are not easy to be blocked; the movable clamp head is more thoroughly detached and cleaned, and time and labor are saved.
