Area of Science:

  • Surgical Technology
  • Minimally Invasive Surgery
  • Robotic Surgery

Background:

  • Telepresence surgery systems offer remote surgical capabilities.
  • Evaluating the efficacy of prototype systems is crucial for advancing surgical technology.

Purpose of the Study:

  • To assess the capabilities of a fully functional, prototype telepresence surgery system.
  • To evaluate the feasibility of performing complete operative procedures using the system.

Main Methods:

  • Experienced surgeons performed various procedures, including cholecystectomy, gastrotomy, enterotomy closures, anastomosis, and nephrectomy, on live anesthetized pigs.
  • The system featured force feedback and high-resolution stereoscopic video input.
  • No specific training was required for system operation.

Main Results:

  • Complete cholecystectomy was successfully performed in six animals without complications or aborted attempts.
  • Other procedures like gastrotomy, enterotomy closures, anastomosis, and nephrectomy were also successfully completed.
  • Operative times were longer than conventional surgery, attributed to the system's manipulator degrees of freedom.

Conclusions:

  • Surgeons can achieve technical results equivalent to conventional surgery using this first-generation telepresence system.
  • The telepresence surgery system demonstrated intuitive operation and effective performance facilitation through force feedback and advanced visuals.
  • The prototype system shows significant potential for future applications in remote and minimally invasive surgery.
