[0002] Abdominal diseases are common diseases in daily life. With the development of laparoscopic technology, traditional open surgery is gradually replaced by laparoscopic surgery. Generally, laparoscopic surgery is to make a small incision on the patient's body wall and insert a pipe-like working channel. All operations are performed through the pipe. Special extended surgical instruments are used to complete the same steps as open surgery under the monitoring of a real-time video system to achieve the same surgical effect. Due to the characteristics of laparoscopic surgery, this puts forward higher requirements on the doctor's operation level. Usually, the doctor's surgical training is carried out on human specimens, which has high training costs, long training cycles, and many inconveniences. If virtual reality technology is used for laparoscopic training, the training effect can be improved. In existing laparoscopic surgery, the eyepiece operation device is mainly used for the positioning of the viewing target, which needs to have the characteristics of accurate operation, flexibility and convenience.
