Problems solved by technology

[0011] The purpose of the present invention is to provide a scalpel interface device with high fidelity, capable of simulating the cutting and acupuncture of human body tissue during the operation, and realizing human-computer interaction in virtual operation training. The non-beneficial comprehensive damping force of interactive devices is a better solution, which effectively solves the problem that passive force tactile interaction devices cannot simulate energy storage elements

Abstract

The invention discloses a scalpel interface device for virtual surgery training to achieve human-computer interaction. The scalpel interface device comprises a mounting base (1) and a scalpel device (14) arranged on the mounting base (1). The mounting base (1) is further provided with a plurality of active / passive hybrid drives and a link mechanism. The scalpel device (14) is connected with the mounting base (1) through the active / passive hybrid drives and the link mechanism. The scalpel interface device for virtual surgery training to achieve human-computer interaction is high in fidelity, and capable of simulating the phenomena of cutting and needling body tissue and other phenomena in the surgery process; the scalpel interface device provides a good solution scheme that active drives are used for compensating non-beneficial comprehensive damping force of passive force sense interaction equipment, and effectively solves the problem that the passive force sense interaction equipment can not simulate energy storage elements.

Description

technical field [0001] The invention relates to the technical field of auxiliary medical devices, in particular to a scalpel interface device used for virtual surgery training to realize human-computer interaction. Background technique [0002] With the development of science and technology, people have higher and higher requirements for the quality of life and health. Countries around the world have put forward higher requirements for the safety of medical technology, especially surgical operations. Statistics show that 80% of clinical operation errors are caused by human errors. of. HealthGrades, a health care rating agency in the United States, conducted a 3-year survey. The results showed that during the survey period, a total of 230,000 people died of surgical errors. Therefore, surgical training is extremely important for the growth of young surgeons. However, traditional surgical training methods There are many problems. In order to solve the limitations of tradition...
