Abstract

A flexible multi-joint operation micro instrument for robot-assisted minimally invasive surgery aims at solving the problem that an existing robot operation micro instrument in minimally invasive surgery can not be positioned, moved and the like in the body of a patient by means of the operation micro instrument. A transmission mechanism is installed on a drive box, six connection holes correspond to a first installation hole, a second installation hole, a third installation hole, a fourth installation hole, a fifth installation hole and a sixth installation hole respectively, and the interior of each connection hole is provided with a transmission element. A first bending transmission mechanism, a second bending transmission mechanism, a third bending transmission mechanism, a fourth bending transmission mechanism, an operating forceps opening and closing transmission mechanism and an operating forceps rotation transmission mechanism are connected with the corresponding transmission elements respectively. The lower end of each transmission element is connected with a micro drive motor. The rear end of a catheter is connected with a catheter fixing element. The front end of the catheter is connected with a flexible bending arm mechanism. The front end of the flexible bending arm mechanism is connected with an operating forceps mechanism. The flexible multi-joint operation micro instrument is used for an abdominal operation.

Description

technical field [0001] The invention relates to a surgical instrument for minimally invasive surgery, in particular to a flexible multi-joint surgical microinstrument for robot-assisted minimally invasive surgery. Background technique [0002] Minimally invasive surgery has the advantages of less bleeding, quick recovery, and low risk of wound infection, and has been recognized in clinical applications. The introduction of minimally invasive surgical robot systems makes surgical operations more precise and stable on this basis. The end effector for minimally invasive surgery is a key instrument in minimally invasive surgery. The invention patent with the Chinese patent number 201310414968.4 and the publication date of December 11, 2013 discloses a micro-instrument for minimally invasive surgical robotic surgery. Due to the design of the patent The flexible wrist mechanism 4 enables this patent to complete the swing and pitch movements of the wrist; however, the guide rod 3 o...
