Abstract

A laparoscopic surgical instrument includes a shaft and a head having a distal end to which a variety of surgical instruments are attached. The laparoscopic surgical instrument also includes a flexible joint installed between the shaft and the head; a longitudinal-driving unit including a longitudinal-driving wire connected with both longitudinal ends of the head and a longitudinal-driving roller turning the longitudinal-driving wire and a transverse-driving unit including a transverse-driving wire connected with both transverse ends of the head and a transverse-driving roller turning the transverse-driving wire. The longitudinal-driving unit turns the flexible joint in the longitudinal direction, the transverse-driving unit turns the flexible joint in the transverse direction, and the shaft has a small diameter.

Description

【Technical field】 [0001] The present invention relates to laparoscopic surgical instruments for laparoscopic surgery, and more particularly to laparoscopic surgical instruments having a small diameter shaft, wherein a flexible joint is mounted between the shaft and the head of the laparoscopic surgical instrument, thereby freely Rotate the head. 【Background technique】 [0002] Laparoscopic surgery is a surgical procedure in which a small incision of about one centimeter is made around the belly button through which an endoscope (laparoscope) and several surgical instruments are inserted to perform the procedure. In contrast to open surgery, laparoscopic surgery typically involves less pain, less scarring, and reduced recovery time after surgery because laparoscopic surgery requires only one or more small incisions in the abdomen. Due to these advantages, the application of laparoscopic surgery as a general diagnostic and therapeutic tool for various diseases has increased. ...
