SURGICAL INSTRUMENT FOR SPINE, AND SURGICAL ROBOT SYSTEM USING SAME

摘要

A surgical instrument for the spine comprises a handle, a tool holder and a tool holder guide. The tool is inserted into the patient's body and drills into the spine. The tool holder is coupled to the tool so as to hold the tool, and advances forwards while being rotated together with the tool by means of a first external force provided from the outside. The tool holder guide is disposed so as to cover at least part of the tool holder and is detachably coupled to the tool holder, and, while coupled to the tool holder, is advanced forwards upon receiving the first external force transmitted from the tool holder, and is detached rearwards from the tool holder such that the tool can be disengaged from a medically affected area by means of second external force provided to the tool holder from the outside. Consequently, risk to the patient during surgery can be prevented.
