Abstract

The utility model relates to a pair of harmless vertebra plate bone clamping forceps, which is composed of a forceps body, a forceps mouth and a handle. The upper and the lower lips of the forceps mouth form different shapes, the upper lip is a type of a bone knife with a hole, and the lower lip is a thin flat plate. The utility model has the advantage of reasonable structure and design, a vertebra plate can be accurately, quickly and conveniently removed under the condition that the spinal cord is not damaged, the difficult problem existing in clinic at present is solved and the therapeutic effect is improved.

Description

Harmless vertebra plate bone clamping forceps

This utility model belongs to uses apparatus on the clinical medicine, relate in particular to a kind of Orthopeadic Surgery laminectomy rongeur.

Operation on spinal cord is removed vertebral plate, and the exposing spinal cord nerve is the successful committed step of operation.The operating theater instruments of removing vertebral plate at present both at home and abroad has two kinds: 1. rongeur, 2. osteotome, the former is narrow and small because of canalis spinalis, the ligule that can hold any more rongeur, to making the vertebral plate can not be vertically stressed, if by force ligule is inserted canalis spinalis, the danger of extruding of causing and Spinal Cord nerve is just arranged, remove vertebral plate have only from the surface pincers difficult unusually as plodding away at a big job bit by bit, and clinically, the decompression of the compression of spinal cord that causes for wound, need in time to finish within a certain period of time, the state of an illness is just controlled or is alleviated, and adopts existing rongeur, often is difficult to realize.Because need between art to consume a large amount of time, delay treatment causes adverse consequences to the patient.Utilize osteotome very easily to cut a hole and hinder spinal cord, the lighter is disabled, weight person's paraplegia.

The purpose of this utility model is exactly can only sting the defective of pincers or cutter from the surface overcoming existing bone forceps, osteotome, through development repeatedly, and then design that a kind of ligule that pincers can be chewed inserts in the canalis spinalis and Spinal Cord not, another ligule is as the novel rongeur of osteotome, thus the function that realization has pincers, cuts a hole, cuts.

Design concept of the present utility model is achieved in that the mechanics principle of comprehensive general rongeur and osteotome, in conjunction with having certain mobility between human physiology's canalis spinalis and spinal cord, pincers are chewed be designed to a ligule and can insert canalis spinalis and the thin flat of non-Spinal Cord, another ligule is designed to osteotome with holes, and this hole is used to get rid of the sclerotin of excision.Two lips of chewing when pincers act on can realize the function that clamps, cut a hole, cut on the vertebral plate.Make it under the situation of Spinal Cord not promptly accurately to excise vertebral plate rapidly again easily, solve the difficult problem of present clinical existence, improve cure rate.

This utility model by caliper, pincers chew, handle three parts form.

The utility model will be further described below in conjunction with accompanying drawing:

Fig. 1 is a surface structure sketch map of the present utility model,

Fig. 2 is that this utility model pincers are chewed the upper lip structural representation,

Fig. 3 is that this utility model pincers are chewed the upper lip cut-away view,

Fig. 4 is that this utility model pincers are chewed the lower lip structural representation,

Fig. 5 is that this utility model pincers are chewed the lower lip cut-away view,

Wherein: 1 handle, 2 calipers, 3 pincers are chewed, 4 upper lips, 5 lower lips, 6 Os Sus domestica holes.

Embodiment of the present utility model is such: pincers are chewed cast variform two

lips

4,5 up and down, its upper lip 4 is a sharp keen osteotome with holes, this hole is positioned on the plane of ligule, utilize this hole to get rid of and downcut sclerotin, lower lip is a thin flat, claim safeguard again, mobility is suitable mutually between its thickness and canalis spinalis and spinal cord.

Advantage part of the present utility model is: this apparatus structure is reasonable in design, can be implemented in the situation of not damaging spinal cord, accurately, rapidly, removes easily vertebral plate, has solved the difficult problem of present clinical existence, improves result for the treatment of.

Claims

A kind of not damaged laminectomy rongeur, it is chewed three parts by handle, caliper, pincers and forms: it is characterized in that clamping the upperlip of chewing and be difformity, its upper lip is an osteotome type with holes, and lower lip is a thin flat plate.
