Embodiment Construction

[0011] The specific implementation manners of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0012] Depend on Figure 1-Figure 3 Given, the structure of the present invention is that the hook body has a free end 1 and a connection end 2, the length of the free end of the hook body is less than the length of the connection end, the top 3 of the hook body is planar, and the connection end of the hook body and the handle 4 are V The V-shaped opening and the opening of the hook body are in opposite directions, and the free ends of the handle and the hook body are respectively placed on both sides of the connecting end of the hook body.

[0013] The hook body is a hook structure formed by bending a steel plate with a thickness of 2-4mm and a width of 0.8-2cm.

[0014] Spike-shaped teeth 5 are evenly distributed on the inner wall of the hook to prevent slippage.

[0015] The connecting end 2 of the hook body and the handle ...

Abstract

The invention relates to a lamina lifter, which effectively solves the problem that the rongeur is inconvenient to use, difficult to operate, and poor in effect during the operation of opening the door and opening the lamina in posterior cervical surgery, and the lamina tends to rebound when it is lifted , leading to the problem of dangerous accidents, the hook body has a free end and a connecting end, the length of the free end of the hook body is less than the length of the connecting end, the top of the hook body is flat, the connecting end of the hook body and the handle are connected in a V shape, V-shaped The opening and the opening of the hook body are in opposite directions, and the free ends of the handle and the hook body are respectively placed on both sides of the connecting end of the hook body. The problem of springback when opened avoids the occurrence of medical accidents and improves the safety of surgery.

Description

technical field [0001] The invention relates to a medical device, in particular to a lamina retractor. Background technique [0002] Due to the continuous improvement and promotion of anterior cervical surgery, clinically good results have been achieved in the treatment of lower neck and short-segment cervical myelopathy, but it is still extremely difficult to solve multi-segment cervical myelopathy. Therefore, posterior cervical surgery has become a common surgical method for the treatment of multi-segment cervical spondylotic myelopathy. Posterior surgery is to expand the spinal canal and rely on the existence of the physiological radian. The spinal cord moves backward under the action of the "bowstring principle" to relieve the compression of the spinal cord by the anterior constrictor. [0003] At present, the surgical steps of posterior cervical surgery are as follows: the patient is placed in a prone position, the neck is flexed, and the upper body is raised. With lo...
