Key result
Autonomous surgical knot tying using stereoscopic view and force feedback was demonstrated to be feasible in an experimental robotic telemanipulator system.
The study demonstrates the first successful implementation of autonomous surgical knot tying using a robotic telemanipulator system equipped with force feedback and stereoscopic vision.
Animal feasibility supports autonomous robotic development; leaves open clinical translation and outcome validation.
The introduction of telemanipulator systems into cardiac surgery enabled the heart surgeon to perform minimally invasive procedures with high precision and stereoscopic view. For further improvement and especially for inclusion of autonomous action sequences, implementation of force-feedback is necessary. The aim of our study was to provide a robotic scenario giving the surgeon an impression very similar to open procedures (high immersion) and to enable autonomous surgical knot tying with delicate suture material. In this experimental set-up the feasibility of autonomous surgical knot tying is demonstrated for the first time using stereoscopic view and force feedback.
