Summary
The SPRINT robotic system enables bimanual interventions through a single-access port, enhancing surgeon dexterity in minimally invasive surgery. This novel platform successfully performed intestinal anastomosis and vessel ligation in an animal study.
Area of Science:
- Robotics in Surgery
- Minimally Invasive Surgery
- Surgical Innovation
Background:
- Single-access procedures are gaining traction but present challenges like impaired eye-hand coordination.
- Robotic-assisted surgery offers a solution to enhance surgeon dexterity in laparoscopic procedures.
Purpose of the Study:
- To introduce and evaluate a novel teleoperated robotic system, SPRINT (Single-Port lapaRoscopy bImaNual roboT), for bimanual interventions via a single-access port.
Main Methods:
- Development of the SPRINT system, a master-slave robotic platform with two 18mm arms and a stereoscopic camera, insertable via a 30mm introducer.
- Surgeon console includes two master manipulators, a foot-switch, and a 3D full-HD display.
- System tested in an animal study on a 50kg female pig.
Main Results:
- Successful execution of two surgical maneuvers: small-bowel enteroenterostomy (intestinal anastomosis) and ligation of a mesenteric vessel bundle.
- Preliminary experience involved placing the system through a 10cm incision, with the robot suspended due to prototype constraints.
Conclusions:
- The SPRINT surgical platform successfully performed complex maneuvers, demonstrating adequate speed, precision, and force.
- Bimanual robotic solutions like SPRINT show promise for improving dexterity and precision in future single-port surgical techniques.
