ABSTRACT

BACKGROUND: In endoscopic surgery, surgeons collaborate with assistants to manipulate the endoscope and instruments, making it impossible to perform the surgery independently.

METHODS: We propose an endoscopic assistive robot based on motion capture control, enabling surgeons to control the endoscope with one hand. The system uses cameras at the master end to capture real-time motion information from the marker accessory, determining the surgeon's intent. It then controls the robot at the slave end to simulate surgical delivery actions, enabling precise endoscopic positioning through master-slave mapping. The omnidirectional wheel design addresses coupling issues of traditional friction wheels, significantly improving control accuracy.

RESULTS: Testing demonstrated a maximum delivery error of 3.99% and 45.77% improvement in rotational precision. The system received positive feedback in both simulated and animal trials.

CONCLUSIONS: The system empowers surgeons to perform endoscopic procedures independently, establishing a foundation for advancing diagnosis and treatment of gastric diseases.
