Recently, a robotic system was developed to assist in Single-Port Endoscopic Surgery (SPS). However, the existing system required a manual operation of vision and viewpoint, hindering the surgical task. We proposed a surgical endoscopic robot for SPS with a dynamic vision control, the endoscopic view being manipulated by a master controller. The prototype robot consists of a manipulator for vision control, and dual tool tissue manipulators (gripping: five DOFs; cautery: three DOFs) can be attached at the tip of the sheath manipulator. In particular, this paper focuses on the details of the mechanism and control scheme of the tool manipulator. The experimental results show that our manipulator exhibits a response with a precision of less than 0.15 mm and a time delay of less than 31 ms, when the input frequency is 1.0 Hz.

Abstract Background Scar visibility is a major deterrent to patients seeking reconstructive surgery. Endoscopic surgery can address a wide range of problems, from minimizing or concealing scars to improving access and outcomes in certain situations. This case series includes a wide range of reconstructive surgery problems addressed by subcutaneous endoscopic surgery. Having one or more trained assistants is a major deterrent to the performance of endoscopic surgery by the lone practitioner. The single (or two-port technique for muscle harvest) used in most cases simplifies subcutaneous endoscopic surgery. Methods A single-port endoscopy technique, with a 4-mm, 30-degree side viewing telescope and sheath, optical camera and cold light source, was used. Case records were reviewed for access incisions, procedure abandonment, postoperative pain, complications, and patient satisfaction. Results A total of 53 endoscopic surgical episodes between 2003 and 2013 were reviewed. Using a single port, most cases were done successfully. The access site was changed peroperatively in one case. Complications included transient nerve palsy in one case, which recovered completely. There was minimal intraoperative bleeding. Postoperative pain was low except in one case and managed with minimal analgesia. Patient satisfaction was high in all cases. Conclusions Subsurface endoscopy done on a wide range of reconstructive surgery procedures and resulted in minimal scars and high patient satisfaction.
