Problems solved by technology

However, some parts of the human body where the central nervous system is concentrated, such as the cervical spine and lumbar spine, have high requirements for medical personnel during the surgical treatment process, the operation is delicate, and the patient cannot move at will.
In the prior art, instrument forceps are generally used to open the incision during surgery. Since it is not a special medical instrument, the strength is small when it is opened, and it is easy to shake. At the same time, it takes up more space, and the operation is inconvenient. And damage the nerves, leading to the failure of the operation and affecting the health of the patient

Abstract

The invention relates to a universal draw hook for human body operation, which belongs to the technical field of medicinal instruments. The universal draw hook comprises a fixing device, a universal adjusting assembly, a draw hook adjusting assembly and a clamp adjusting assembly, wherein the universal adjusting assembly is connected with the draw hook adjusting assembly through the fixing device, and the adjusting positions of the adjusting assemblies can be relatively moved; and the clamp adjusting assembly is fixed on the universal adjusting assembly and can control ascending and descending of the universal adjusting assembly. The universal draw hook has a reasonable structural design, can stably spread the incision in the open operation of the human body to achieve successful operation, meanwhile can flush the incision, and is very practical.

Description

technical field [0001] The invention relates to a universal retractor used in human body surgery, which is mainly used to open the incision during open surgery on the human body, and belongs to the technical field of medical equipment. Background technique [0002] Open surgery on the human body is widely used in medicine. During the operation, the incision needs to be propped open so that the operation can proceed smoothly. However, some parts of the human body where the central nervous system is concentrated, such as the cervical spine and lumbar spine, have high requirements for medical personnel during the surgical treatment process. In the prior art, instrument forceps are generally used to open the incision during surgery. Since it is not a special medical instrument, the strength is small when it is opened, and it is easy to shake. At the same time, it takes up more space, and the operation is inconvenient. And damage the nerves, leading to surgical failure, affectin...
