Development and evaluation of a master-slave robot system for single-incision laparoscopic surgery

Single-incision Laparoscopic Surgery

in many gynecologic procedures with better results in terms of minimal perioperative morbidity and shorter hospital stay, with consequent improved quality of life compared to laparotomic approach1,2. Despite this wellknown advantages, laparoscopy still requires 0.5 to 1.5 cm long incisions and three to five ports to be performed, each working port implying with an inherent risk of bleeding, inf...

Master–slave manipulator for laparoscopic surgery using a 6-axis vertical articulated robot

Laparoscopic surgery is a minimally invasive surgery that accelerates postoperative recovery, but it can only be performed by surgeons with advanced surgical skills. One of the main difficulties in laparoscopic surgery is restriction of free motion of the forceps because of limited degrees of freedom by the trocar. Recently, many master–slave manipulators with a remote center-of-motion mechanis...

Single – Incision Laparoscopic Surgery for Rectal Cancer

There have been major advances in the treatment of rectal cancer in the last two decades. Improvements in surgical instrumentation has dramatically impacted the surgical approach to rectal cancer. Particularly laparoscopic procedures have been assumed a central role in the management of benign and malignant colorectal diseases as a result of a recent paradigm shift toward minimally invasive sur...

Single Incision Laparoscopic Surgery (SILS) for Cholecystectomy

Single-Incision Laparoscopic Surgery for Intersigmoid Hernia

Intersigmoid hernia is a rare form of internal hernia. Here, we report a case of intersigmoid hernia and provide a brief review of the 62 cases involving the mesosigmoid reported in Japan from 2000 to 2013. In the current case, a 26-year-old man with no previous history of abdominal surgery presented with abdominal pain and vomiting. Abdominal computed tomography revealed an extensively dilated...
