Abstract

The invention relates to a surgical robot end mechanism. The surgical robot end mechanism comprises an execution assembly, an autorotation device, a push broach device and an opening and closing device, the execution assembly comprises a fixed finger and a movable finger, the first end of the movable finger is matched with the fixed end of the fixed finger in a hinged mode, and the second end of the movable finger is configured to be a free end; The autorotation device comprises a sleeve and an autorotation driving module, and the autorotation driving module drives the fixed finger to rotate through the sleeve; The push broach device comprises a push broach driving rod and a push broach linear driving module, the push broach linear driving module drives a push broach to do linear reciprocating motion through the push broach driving rod, the push broach linear driving module is arranged in the rotation driving module, and the opening and closing device comprises an opening and closing push rod and an opening and closing linear driving module. The opening and closing linear driving module drives the movable finger to deflect through the opening and closing push rod, and the opening and closing linear driving module is arranged in the push broach linear driving module, so the technical problems that in the prior art, a surgical robot tail end mechanism is large in part number, large in weight, large in size and poor in stability are solved.

Description

technical field [0001] The invention relates to the field of minimally invasive surgical instruments, in particular to a terminal mechanism of a surgical robot. Background technique [0002] Minimally invasive surgery has been more and more widely used in clinical surgery because of its characteristics of less trauma, less bleeding, and faster recovery. It is of great significance in terms of invasive surgery. There are following problems in current surgical instruments: [0003] 1. The transmission device and the driving device of the device are set at the same end or the transmission device is set close to the execution end, which makes the device have many parts, heavy weight, large volume, and easy coupling. In addition, the accumulation of tolerances of many parts makes the device The accuracy is poor and the stability is poor. [0004] 2. The doctor manually provides force to control the execution end to rotate, open and close, and push the knife. In this way, the d...
