The invention discloses a robot arm of operation, comprising surgical knife feeding mechanism, wrist, parallelogram mechanism, forearm 1 revolving gear and arm revolving gear. The surgical knife feeding mechanism (15) comprises feed screw (43), motor reducer (44), motor 2 (45), slide rod (46), two circular lead rails (47) and connecting bracket (48). The wrist comprises ball (17), three drive rods(18) and wrist driver (19). The parallelogram mechanism comprises rotating shaft sleeve (38), drive arm (14), parallelogram connecting rod 1 (22), parallelogram connecting rod 2 (24), connecting rodsupport (11) and parallelogram rotating cradle head (12). The forearm revolving gear comprises forearm (10) and forearm 1 cradle head (8). The arm revolving gear comprises arm (9) and arm cradle head(4). The forearm 1 and arm are circular hollow pipe fitting. The structures of the parallelogram mechanism cradle head, forearm 1 cradle head and arm cradle head are the same.

Description

technical field [0001] The invention relates to a surgical robot arm, which belongs to the field of medical equipment. It is suitable for medical equipment for minimally invasive surgery. Background technique [0002] With the application and development of robot technology, especially the development of computing technology, the role of medical surgical robots in clinical practice has been paid more and more attention. The application of minimally invasive surgery technology is a great revolution in the field of surgery in the 20th century. Its application makes most of the surgery say goodbye to the open operation mode. Compared with traditional open surgery, minimally invasive surgery only makes a small incision on the patient's body for surgical operation, which has the advantages of less surgical trauma, less pain for patients, faster postoperative recovery, lower surgical costs, and less postoperative pain. Complications and other advantages. Therefore, it has been ...
