Abstract

Recently the trend of surgical procedure for treatment of lumbar benign disease is a minimally invasive surgery due to small incision, minimal blood loss, and a short hospital day. By using a microscope or an endoscope, and other surgical equipment, a delicate manipulation in a narrow space became feasible, consequently, to secure a wider view with small incision, appropriate retractors are required. But the various tubular retractor systems are expensive and have some problems. We modified Thoracoport [Auto Suture Co., Norwalk, CT] by making a window at the distal end of trocar and used it as a tubular retractor in surgical procedure for treatment of lumbar benign disease. This modified tubular retractor is docked closely on the curved lamina and provides a wider view. We used it as a tubular retractor also in lumbar bilateral decompression involving a unilateral approach. But this trocar has the limited sizes [diameter and length], and also it is difficult to fix the retractor or change the direction of retractor. And then, we propose a more modified Thoracoport with various sizes and attaching the settling holders to the head of tubular retractor to be able to fix the retractor.
