The concatenated surgical operation instrument in order to do lowest invasion Characteristic surgical operation with skill Characteristic and the sensitivity which improve

摘要

(57) Abstract This invention is the concatenated surgical operation instrument tool which improves the operation of lowest invasive Characteristic surgical operation procedure (12). The instrument (12), high-level skill Characteristic, low friction, it possesses low inertia, and satisfactory power reflection. With the unique cable and the pulley Drive system, friction decreases and power reflection improves. Skill Characteristic of surgical operation improves with unique list feature, the canonical intraperitoneal mirror instrument (12) with in comparison. Number of the necessary actuators decreases by optimizing the system, sufficiently functional concatenated surgical operation instrument tool is produced because of this at the smallest size.
