Anterior cervical surgery gap retractor

Abstract

Disclosed is an anterior cervical surgery gap retractor comprising a plurality of retractors, each retractor comprises a telescopic rod, one end of each telescopic rod is connected with a retracting rod through a joint structure, the end of each retracting rod is of a sharp structure, and each retracting rod is provided with a hollow depth limiting ball. The depth limiting ball comprises a lower hemisphere part fixed to the retraction rod and an upper hemisphere part slidably connected with the retraction rod, a plurality of leakage holes are formed in the lower hemisphere part, the other end of the telescopic rod is slidably connected with the guide rail, and a fixing piece is fixed to the guide rail and can be fixedly connected with an operating bed. A good surgical field of vision is exposed. And the labor intensity of medical staff is reduced.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a space retraction device for anterior cervical surgery. Background technique [0002] The statements herein merely provide background information related to the present invention and do not necessarily constitute prior art. [0003] In the field of spinal surgery, especially anterior cervical surgery, it is often necessary to retract soft tissues such as vascular sheaths, visceral sheaths, nerves, muscles, skin, and subcutaneous tissue to expose bone tissues for surgical operations. The surgical site is deep, the visual field is narrow, and the retracted tissue is fragile and easy to be damaged. It requires gentle distraction and good visual field exposure. The inventor found that the current retractors or retractors are manually stretched and stretched. The first disadvantage is that they cannot be anchored to the stretched part, and they are easy to slide, rub, an...

Problems solved by technology

The inventor found that the current retractors or retractors are manually stretched and stretched. The first disadvantage is that they cannot be anchored to the stretched part, and they are easy to slide, rub, and move, and are easy to damage soft tissues, which also affects the exposure of the surgical field of view; The hook needs to be held by an assistant for a long time, which consumes manpower and physical strength

If Kirschner wires are used to anchor the target vertebral body, the disadvantages are firstly that it is difficult to control the penetration depth, and it is easy to damage the deep spinal cord, nerves or vertebral arteries; The assistant continues to hold the retractor
