Retractor direct access endoscopic surgery, tools and methods

摘要

(57) retractor endoscope endoscopic surgery for direct access less of [summary] invasive includes (32) rigid framework having a support capacity of the applied load required by the regression Kyoko of the incision site (Figure 2). Rigid framework comprises a lower blade block which is rotatably connected to the other end (33), handle (28) to the first end. Transfer frame (38) is connected slidably to the rigid framework comprises an upper blade base that is rotatably connected to the transfer frame (39). Is mounted can be removed in the upper blade base and lower, respectively, upper and lower blade (20, 22) comprises a pivot block of the high-strength fiber optic (70) One of the blade at least. The angle of the upper blade of the rotatable connection along the upper blade platform and the angle of the lower blade of the rotatable connection along the lower blade platform is adjustable independently. The magnitude of the surgical window is determined by the angle of the blade and upper side and the lower side of the upper blade distance between table and lower. Method of open surgery with less direct access of invasive involves the use of retractor associated (Figure 3) tool having an angled handle.
