DEVICE FOR MEASUREING A ENVIRONMENT INTERACTION TORQUE, SURGICAL ROBOT AND SURGICAL ROBOT SYSTEM WITH THE SAME

摘要

According to an embodiment of the present invention, a contact torque measurement device includes: an instrument which performs operation of burning or cutting biological tissue through electrical operation with three degrees of freedom in rotational (ROLL, PITCH, YAW) motions based on the X, Y and Z axes with respect to a support point or an RCM point; a cannular which is inserted into a human body to guide the instrument into the human body; and a docking clamp which fixates and supports the cannular to a slider which performs a translation motion and has a strain gauge sensor to measure a torque due to a contact force generated in a contact point with the cannular when the instrument invades into a human body. The present invention can improve the accuracy of operation by accurately receiving an interaction generated while the surgical robot and human organ are in contact when a surgeon conducts minimal invasive surgery by measuring a torque generated by a contact force at the end of the instrument with the strain gauge sensor attached to the docking clamp when the docking clamp which is to fixate the cannular, through which the instrument is inserted, is inclined while performing a rotational motion (ROLL, PITCH) based on the X-axis or Y-axis with respect to the support point.
