Problems solved by technology

However, in the vast majority of minimally invasive surgical operations currently performed in patients, the space left for doctors to operate is very small, and the above-mentioned large-angle rotation movement is easy to accidentally touch or even scratch other important organs, causing accidents. Bleeding, even threatening the patient's life

Abstract

The invention provides a surgical instrument tail end structure of a minimally invasive surgery robot. A first joint rotating base back end is fixedly connected with a connecting cylinder front end of a surgical instrument, a first joint rotating base front end is hinged to a second joint rotating base back end, and accordingly a bending freedom degree is achieved. A second joint rotating base front end and a third joint rotating base back end are hinged, and a rotating freedom degree is achieved. A third joint rotating shaft back end is arranged at a third joint rotating base front end through a bearing to achieve a torsion freedom degree. The back end of a jaw fixing part is fixedly connected with the front end of a third joint rotating shaft, a jaw moving piece is hinged to the jaw fixing part, and accordingly a jaw opening freedom degree is achieved. The four freedom degrees are controlled by a steel wire rope connected into a cylinder, the four freedom degrees simulate moving functions of all doctor arm joints of shoulder joints, elbow joints and wrist joints, and accordingly the safety of minimally invasive surgery is effectively improved.

Description

technical field [0001] The invention relates to the technical field of surgical instruments, in particular to an end structure of a minimally invasive surgical robot. Background technique [0002] Minimally invasive surgery has become more and more popular among patients because of its advantages such as less trauma, less pain, shorter hospital stay, and faster recovery of body functions, bringing good news to patients. However, some characteristics of minimally invasive surgical instruments themselves, such as limited dexterity, limited field of view, and mirror movement effects of slender surgical instruments, make higher requirements for doctors when performing minimally invasive surgery. In recent years, in order to solve the obstacles caused by traditional minimally invasive surgical instruments to doctors, master-slave teleoperation robot technology has been introduced into minimally invasive surgery, such as Da Vinci surgical robot (Intuitive Surgical, Inc.), this Th...
