Abstract
The invention discloses vertebral plate rongeur which mainly comprises a fixed tong head, a movable tong head, a steering knuckle, a push rod, an inner push rod, a tong rod, a front handle, a rear handle, a rivet and inner chutes, wherein the inner chutes are arranged on two sides of the fixed tong head, the movable tong head, a plurality of steering knuckles and the push rod 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 the push rod is butted with the tong rod, the tong rod is inserted into the inner push rod, the front end of the inner push rod is connected with the fixed tong head, the rear end of the inner push rod is connected with the rear handle, the rear end of the tong rod extends into the rear handle and is connected with the front handle. 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.
Description
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.

Description of reference numerals: the automatic clamp comprises a fixed clamp head 1, a movable clamp head 2, a steering knuckle 3, a push rod 4, an inner push rod 5, a clamp rod 6, a front handle 7, a rear handle 8, a rivet 9, an inner chute 10, an original fixed clamp head 11, a driving clamp head 12, an original inner push rod 13, an original clamp rod 14, an original front handle 15 and an original rear handle 16.
Detailed Description
The invention will be described in detail below with reference to the following drawings:
Example (b): as shown in the attached drawings, the vertebral plate rongeur mainly comprises a fixed tong head 1, a movable tong head 2, a steering knuckle 3, a push rod 4, an inner push rod 5, a tong rod 6, a front handle 7, a rear handle 8, a rivet 9 and an inner sliding groove 10, wherein the tong head of the fixed tong head 1 is large at the outer part and small at the inner part, so that cut broken bones are not easy to be blocked. The fixed binding clip 1 has a certain radian suitable for actual use. During production, the radian, the angle and the bending degree of the fixed forceps head 1 can be adjusted at will according to the actual needs of the operation of doctors to produce and manufacture. Decide binding clip 1 both sides and be provided with interior spout 10, move binding clip 2, install in the interior spout 10 of deciding the binding clip 1 left and right sides and through rivet structural connection after the screens of several knuckle 3 and the 4 screens of tubulose push rod of rear end are established ties together, moreover, the steam generator is simple in structure, the manufacturing is convenient, 4 rear ends of push rod and tong lever 6 butt joints, tong lever 6 inserts in interior push rod 5, interior push rod 5 front end is connected and is decided binding clip 1, back handle 8 is connected to interior push rod 5 rear end, tong lever 6 rear end stretches into back handle 8 and is connected with front handle 7, front handle 7 and back handle 8 are with rivet 9 swing joint.
