Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, specifically to a master hand operating device for an auxiliary operating system in digestive endoscopy surgery. Background Technology
[0002] The digestive endoscopy surgical assistance system is a novel medical device integrating multiple disciplines. It represents an important development direction in the current informatization, programming, and intelligence of medical devices, and has broad application prospects in the field of minimally invasive surgery. The digestive endoscopy surgical assistance system adopts a master-slave remote control mode. The surgeon operates the master hand control device from the console. The movement information of the master hand control device is transmitted remotely to the end effector located at the lesion site within the patient's body. The end effector can move synchronously with the master hand control device to perform the surgery. During the surgery, the end effector can also feed back force signals to the master hand control device, achieving force feedback.
[0003] In existing technologies, when users control the end effector using the master hand, it is easy for the operating range to be too large, causing shaking or acute rebound, which leads to the master hand's rotation range exceeding the normal range and causing additional damage to the patient's affected area.
