The invention discloses a retractor for a minimally invasive surgery. The retractor comprises a rectangular tube I, a rectangular tube II, a rectangular tube III and a rectangular tube IV which are sequentially and fixedly connected end to end, wherein transmission compression bars are connected to inner walls of the rectangular tube I, the rectangular tube II, the rectangular tube III and the rectangular tube IV in a limited sliding manner, opposite surfaces of the rectangular tube I, the rectangular tube II, the rectangular tube III and the rectangular tube IV are fixedly connected with boxes, opposite surfaces of the transmission compression bars on the rectangular tube I, the rectangular tube II, the rectangular tube III and the rectangular tube IV are fixedly connected with transmission plates, and through grooves I allowing the transmission plates to slide are formed in opposite surfaces of the rectangular tube I, the rectangular tube II, the rectangular tube III and the rectangular tube IV. Through cooperative use of the structures, the retractor solves the problems that in actual use, as a traditional retractor is time-consuming and labor-consuming to operate, fixation andtraction of skin at wounds can be completed through operation by multiple people, the working efficiency is reduced and inconvenience is brought to use.
Description
technical field [0001] The invention relates to the technical field of medical equipment, in particular to a retractor for minimally invasive surgery. Background technique [0002] Retractors, also known as retractors, are used to retract tissues to expose the area to be operated on and facilitate exploration and operation. They can be divided into two types: hand-held retractors and automatic retractors. There are various specifications of different shapes and sizes, and the appropriate retractor can be selected according to the needs of the operation; the existing devices used to retract brain tissue during minimally invasive brain surgery are mainly used for the removal of intracerebral hematoma or intracerebral tumors, During intraventricular tumor resection, the brain tissue is retracted to expose the hematoma or tumor tissue. At present, flexible-shaft self-sustaining retractors are widely used in brain surgery at home and abroad. This type of retractor has high requi...
