Embodiment 1

[0036] like figure 1 and 2 As shown, a kind of auxiliary instrument for cervical spine surgery to expose the surgical field of view, the auxiliary instrument includes a fixed backing plate 1 and a head support mechanism 8 arranged at the front end of the fixed backing plate 1 for supporting the patient's head, and when the fixed pad The board 1 is laid on the operating bed. When the patient lies prone on it, the shoulder position is higher than the head position, thereby exposing the neck. On the fixed pad 1, a shoulder muscle stretching and fixing device is arranged. The two stretch straps 501 in the stretch fixation device respectively pull and fix the muscles of the shoulders on both sides backward, thereby fully exposing the back of the cervical spine.

[0037] In this embodiment, the lower bottom surface of the fixed backing plate 1 is a plane, which fits the surface of the operating bed, and the upper surface is parallel to the lower surface, or gradually lowers from th...

Embodiment 2

[0041] like figure 1 , 2 As shown in and 3, this embodiment is an improvement made on the basis of embodiment 1, and its main body is the same as that of embodiment 1. The improvement is that the stretching and fixing device for shoulder muscles also includes an adjustment The bearing mechanism 4, the adjustment bearing mechanism 4 includes a bearing plate 401 that carries the upper body of the patient, and the bearing plate 401 is provided with two slide grooves 406 on the surface of the fixed backing plate 1 through the sliders 407 symmetrically arranged on both sides of the bottom of the bearing plate 401 Internal sliding, the two are surface contact friction sliding, this kind of surface contact friction sliding can realize the adjustment of the sliding position under the action of external force while being stable; a flexible pad 403 is laid on the surface of the bearing plate 401, and the flexible pad Both sides of the front end of 403 are provided with rolled-up fricti...

Embodiment 3

[0045] like figure 1 , 2 As shown in and 3, this embodiment is an improvement made on the basis of embodiment 1 or 2, and its main body is the same as that of embodiment 1 or 2. The improvement is that the two stretching straps 501 are made of The fixing mechanism 5 is fixed, and the fixing mechanism 5 includes two fixing rods 502 and an internally threaded sleeve 503 arranged inside the rear end of the fixing pad 1 and parallel to the width direction of the operating bed. The two stretching bands 501 The front end is fixed to the front end of the bearing plate 401, and the end is fixed on a card 504. One end of each fixed rod 502 is provided with an external thread that cooperates with the internal thread sleeve 503, and the other end is provided with a rotating handle. The shaft at one end of the rotating handle is provided with a through groove for inserting and fixing the card 504 therein. By inserting the cards 504 at the ends of the two stretching straps 501 into the th...

Abstract

The invention relates to an auxiliary instrument for exposing the surgical vision field during posterior cervical spine surgery. The auxiliary instrument comprises a fixed backing plate and a head supporting mechanism which is disposed at the front end of the fixed backing plate and used for supporting the head of a patient; when the fixed backing plate is laid on an operating bed and the patientis prostrate on the operating bed, the shoulders of the patient are higher than the head, and correspondingly the neck is exposed; the fixed backing plate is provided with a shoulder muscle stretchingand fixing device, and two stretching strips in the shoulder muscle stretching and fixing device are used for pulling and fixing muscles of the shoulders on both sides backward, so that the posteriorpart of the cervical spine is exposed completely. The auxiliary instrument is laid on the operating bed during use, and the two stretching strips in the shoulder muscle stretching and fixing device are used for pulling and fixing the muscles of the shoulders on both sides backward after the patient is placed on the fixed backing plate, so that the posterior part of the cervical spine is exposed completely. The fixing mode is not only simple and convenient but also very stable, and the phenomenon of slippage during the surgery cannot occur.

Description

technical field [0001] The invention relates to an auxiliary device used in medical operations, in particular to an auxiliary device for exposing the surgical field of view in the posterior cervical spine operation. Background technique [0002] When performing cervical spine surgery, the patient needs to lie on the operating bed to perform surgery on the back of the patient's neck; the front of the existing operating bed has a U-shaped head ring that supports the patient's head. This U-shaped head ring uses Made of flexible materials such as sponge, so that the patient can support the patient's head when lying prone, and the oxygen tube and other pipelines inserted into the nasal cavity of the patient during surgery are inserted into the nasal cavity from under the U-shaped head ring. [0003] But there are following problems in this operating bed: [0004] 1) The support of the U-shaped head ring to the patient's head is actually supported on both sides of the patient's f...
