Abstract

The invention discloses an eight-degree-of-freedom minimally invasive surgical robot. The robot includes a fuselage base, a drive mechanism arranged on the base, and a surgical instrument case connected to the drive mechanism; the drive mechanism includes a Z-axis rotary drive device, X-axis rotary drive device and RCM telecentric mechanism, the RCM telecentric device includes a Y-direction rotary drive mechanism and an X-direction rotary drive mechanism; the surgical instrument box includes an end effector, a transmission box and a base, and the base is fixed by bolts On the RCM telecentric mechanism, the transmission box transmits the movement to the end effector through the crank linkage mechanism, and the end effector performs corresponding adjustment movements according to the actual situation of the operation through the parallel mechanism, so as to achieve reasonable operation during the operation area, the present invention has outstanding advantages in terms of accuracy and flexibility, reduces operation time and improves operation accuracy and quality.

Description

technical field [0001] The invention relates to a robot, in particular to an eight-degree-of-freedom minimally invasive surgical robot. Background technique [0002] As a part of modern medical surgery, minimally invasive abdominal surgery has been widely used clinically to treat various celiac diseases in humans. However, traditional abdominal surgery requires the combination of the doctor's eyes and hands, and the operation is performed with the help of the doctor's experience. Tremors lead to excessively large wound areas and slow recovery of patients after surgery. At the same time, standing for a long time during surgery, the doctor's fatigue operation will cause deviations in the accuracy of surgical instruments. [0003] With the development of science and robotics, robots have shown great potential and application prospects in the medical field. Surgical robots have shown outstanding advantages in terms of stability, safety and feasibility, which can increase the fle...
