Title:
RCM STRUCTURE FOR A SURGICAL ROBOT ARM
Document Type and Number:
WIPO Patent Application WO/2011/149260
Kind Code:
A2
Abstract:
The present invention relates to a remote center of motion (RCM) structure for a surgical robot arm. The RCM structure for a surgical robot arm is configured such that an end of the robot arm is equipped with a surgical instrument such that the surgical instrument is rotatable about a point of an RCM. The RCM structure for a surgical robot arm comprises: a base; a first link unit coupled to the base such that the first link unit is rotatable in both directions about the virtual line interconnecting the base and the RCM point; and a second link unit which is rotatably coupled to the first link, and the end of which is equipped with the surgical instrument. The first and second link units are rotatable by 360 degrees with respect to the base so as to significantly increase the range in which the surgical instrument rotates about the RCM point, thereby enabling the surgical robot arm to operate in a wider range while maintaining the RCM.
