Abstract

The present invention discloses a linear driving device of a surgical robot and the surgical robot. A technical scheme is as follows: the linear driving device of the surgical robot comprises a rotational freedom degree module, a device driving module, a motion transmission module and a quick change module, the rotational freedom degree module is connected with device driving module, an output endof the device driving module is connected with the motion transmission module, and an output end of the motion transmission module is connected with the quick change module. A rotation motion of thedevice driving module is changed into a linear motion through the motion transmission module and transmitted to the quick change module, so that quick changes are realized. The linear driving device of the surgical robot can better realize the quick changes of different end actuators. The linear driving device of the surgical robot has universality, can realize a modularized use of a surgical robot system, and reduces use cost.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a linear drive device for a surgical robot and a surgical robot. Background technique [0002] With the development of minimally invasive surgery, the use and research of surgical robots have developed rapidly. At present, surgical robots can be divided into rod drive, built-in elastic element drive, and wire drive according to the driving mode. The size of the small surgical robot is more conducive to the development of minimally invasive surgery, so it has been widely used. [0003] At present, the driving device used in the world's most commercially successful surgical robot-Da Vinci surgical robot is the wire-driven driving method. The surgical robot produced by Da Vinci is used in the field of laparoscopic surgery. It uses a DC servo motor as the power device, and the output motion is converted into the translational motion of the driving wire through the turntable transm...
