A space retraction device for anterior cervical surgery

Abstract

The invention relates to a space retraction device for anterior cervical surgery, which includes a plurality of retractors, the retractors include telescopic rods, one end of the telescopic rods is connected with a retractor rod through a joint structure, and the end of the retractor rod is a pointed structure. The retraction rod is provided with a hollow depth-limiting ball. The depth-limiting ball includes a lower hemispherical part fixed with the retraction rod and an upper hemispherical part slidingly connected with the retraction rod. The lower hemispherical part begins to have multiple leakage holes. The other part of the telescopic rod One end is slidingly connected with the guide rail, and the guide rail is fixed with a fixing part, which can be fixedly connected with the operating bed through the fixing part. The device of the present invention can expose a good surgical field of vision and reduce the labor intensity of medical staff.

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
