The first case in China! Shanghai Jiao Tong University's self-developed single-hole surgical robot shows its ability!

A few days ago, the Surgerii single-port endoscopic surgical robot independently developed by a team led by Shanghai Jiao Tong University and a number of domestic superior colleges and high-tech companies, led by Professor Xu Kai of the School of Mechanical and Power Engineering, completed the first case in China at the Jiaxing First Hospital A radical prostatectomy performed under a pure single port. The robot project has received special funding from the national key research and development plan "Digital Medical Equipment Research and Development", has complete independent intellectual property rights and has mastered the key technologies of the entire chain.

The products independently developed by China this time have rarely been "It has not been imported, that is, it has been replaced."

Professor Xu Kai`s team has concentrated on researching single-hole surgical robots for more than ten years, using completely independent original design and theoretical system, breaking through the key technology of the whole chain of system research and development, and developing a single-hole surgical instrument based on high-rigidity deformable serpentine continuum surgical instruments. Laparoscopic surgery system. The system contains 68 high-precision servo motors, which are used for preoperative automatic positioning, intraoperative operation and master-slave control. Creatively designed the dual-loop independent control hardware topology for full-state safety monitoring, the full-link master-slave operation delay is less than 50 milliseconds, and 1000 sub-millimeter-level operations can be accurately controlled per second. The project has completed more than 280 patent applications and formed a complete independent intellectual property system.

Single port surgery and robot

Single port surgery is an internationally advanced new generation of minimally invasive surgery. It only needs to make a small opening of 2.5 cm in diameter at the patient's belly button, and this robot can insert a 3D high-definition electronic endoscope and three flexible and flexible snake-shaped surgical instruments to complete the operation. The surgical trauma is small, the recovery is quick, and there is no obvious scar after the operation. This operation was performed by Professor Wang Linhui, director of the Department of Urology, Changhai Hospital, as a technical expert. According to the 3D high-definition field of view provided by the robot, the tumor boundary is accurately judged, and the high-rigidity continuum serpentine surgical instrument with full-dimensional motion capability is used to delicately complete the surgical operation, complete the extracapsular resection of the tumor, and complete the anatomy efficiently Structural reconstruction and wound suture, less bleeding during the operation, short operation time, complete resection of the lesion, and a complete success in the operation.

The single-hole surgical robot is the most difficult surgical robot to develop. Previously, only the Da Vinci single-hole surgical robot of the American Intuitive Surgery Company was used for human surgery, but the company has implemented export controls on this most advanced surgical product and has not yet allowed sales to the Chinese market.

Compared with the Da Vinci single-hole surgical robot, it is necessary to arrange auxiliary holes on the side of the patient's belly button to assist in the operation during the operation. This operation only needs to be completed in a single-hole way, which highlights the excellence performance of the surgical sharp robot. Professor Wang Linhui spoke highly of the robot after the operation: This robot is an original product created by the R&D team after drawing on many years of clinical experience in robotic endoscopic surgery in the Department of Urology of Changhai Hospital. Aiming at the difficulties and pain points of single-port laparoscopic surgery, snake-shaped surgical instruments and 3D high-definition electronic endoscopes have been specially developed for the implementation of pure single-port surgery. When performing radical prostatectomy, doctors can quickly and efficiently complete tumor removal, suture reconstruction and other operations in a small surgical space. The clarity of vision, operational fluency, and operation efficiency are completely comparable to the current global monopoly of Da Vinci. Single port laparoscopic surgical robot.
