RETRACTOR ASSEMBLY FOR MINIMALLY INVASIVE SURGERY

摘要

The present device relates to a retractor assembly for minimally invasive surgery, comprising: a main body which is inserted through an opening of a patient, has a channel formed therein, and of which both ends are penetrated; and a tip unit which is provided on the distal end of the main body, and of which the edge of the end portion is formed to correspond to the shape of the outline of the patient's bone which is the part subject to surgery. Thus, the retractor assembly for minimally invasive surgery is capable of stable and reliable surgery without touching sensitive and dangerous parts such as body fluid tubes through which body fluids flow, blood vessels, and ligaments.
