Technique for Docking and Port Placement Using a Purpose-built Robotic System (SP1098) in Human Cadaver

Area of Science:

• Urology
• Minimally Invasive Surgery
• Robotic Surgery

Background:

• Robotic surgery has advanced minimally invasive procedures.
• The development of new robotic platforms aims to further enhance surgical capabilities.
• Single-port and reduced-port-count extracorporeal (R-LESS) surgery offers potential benefits in reducing invasiveness.

Purpose of the Study:

• To detail the port placement and robot docking procedures for a novel robotic platform designed for R-LESS urological surgeries.
• To evaluate the feasibility of accessing the pelvic fossa and retroperitoneum using this new system in a preclinical cadaver model.

Main Methods:

• A preclinical study utilizing human cadavers was conducted.
• The da Vinci SP1098 surgical system was employed to perform R-LESS prostatectomies, cystoprostatectomies, and nephrectomies.
• Procedures included transperineal, transvesical, and retroperitoneal approaches, with assessment of port placement, docking, and operative feasibility.

Main Results:

• Fourteen procedures were successfully completed on 12 cadavers, including various prostatectomy and nephrectomy types.
• Operative times were comparable to standard multiport robotic surgery.
• No intraoperative complications or need for additional ports/instruments were observed.

Conclusions:

• The SP1098 robotic platform demonstrates reproducible and feasible port placement and robot docking for R-LESS pelvic fossa and retroperitoneal urological procedures.
• This preclinical study supports the potential of the SP1098 system for advanced minimally invasive urological surgery.
