Abstract
The utility model relates to an adjustable ring cervical vertebrae rear fixer which comprises an upper and a lower half ring bars, wherein the four end heads of the two half ring bars are respectively bent into a ring-shaped hole, and the two half ring bars are mutually penetrated and inserted and can freely slide to adjust a fixing range. When the utility model is used, the fixer only needs to be wound on the cervical spine of a patient by a steel wire. The utility model has the advantages of convenient fabrication, convenient operation, reliable fixation, strong practicality, no side effect, etc. Thereby, the utility model is especially suitable for the rear operation of the unstable damage of the cervical vertebra in orthopaedics.
Description
This utility model belongs to medical apparatus and instruments, is specifically related to a kind of adjustable ring-type posterior cervical holder that is used for the orthopaedics clinical operation.
At present, the way of escape holder that the unstable trauma surgery of cervical vertebra is used is generally steel wire or steel plate with holes clinically, uses the fixation with steel wire poor stability, is unfavorable for that cervical vertebra resets fixing and healing; Fix with steel plate with holes, because of cervical vertebra position fixed angle is had relatively high expectations, easy damaged vertebral artery blood vessel in the operation technique.
The purpose of this utility model solves the problem that existing operating theater instruments exists with regard to being, a kind of adjustable ring-type posterior cervical holder simple, easy to operate, fixed, practical and without any side effects of making is provided.
The purpose of this utility model realizes by following measure.Adjustable ring-type posterior cervical holder comprises two semi-ring rods up and down, and two semi-ring rods are made by the medical stainless steel material.Two terminations of last semi-ring rod curve looping pit respectively, and two terminations of following semi-ring rod are passed two looping pits of semi-ring rod respectively, are wrapped in then on the barred body of semi-ring rod and curve looping pit.
Described up and down two semi-ring rods can intert slip mutually.
Below in conjunction with accompanying drawing this utility model is done detailed description.
Fig. 1 is this utility model front view.
Fig. 2 is this utility model side view.
As shown in Figure 1 and Figure 2, semi-ring rod 1, semi-ring rod 2 are made by the medical stainless steel material.Two terminations of semi-ring rod 1 curve looping pit 3 respectively, and two terminations of semi-ring rod 2 are passed two looping pits 3 of semi-ring rod 1 respectively, are wrapped in then on the barred body of semi-ring rod 1 and curve looping pit 4.Semi-ring rod 1, semi-ring rod 2 intert and can slide over each other in looping pit 3,4, to play the effect of regulating this holder length.This holder is scalable fixed range up and down not only, and its width, radian all can be regulated according to the operation needs.
This utility model is very easy to use, and only this holder need be fastened with steel wire gets final product on patient's cervical spine.Because holder contact with cervical spine and coincide tightlyer, therefore fixed, is difficult for looseningly, benefits cervical vertebra and resets and fix and heal.
Compared with prior art, the utlity model has make simple, easy to operate, fixed, The advantage such as practical and without any side effects is specially adapted to the unstable damage of orthopaedics cervical vertebra patient and exists Use in the operation.
