ABSTRACT:
A laparoscopic instrument assembly includes a rigid sleeve and a plurality of laparoscopic instrument shafts inserted inside the sleeve. The sleeve has an outer diameter smaller than an inner diameter of a laparoscopic cannula, whereby a distal end portion of the instrument assembly may be inserted into a patient's abdomen through the laparoscopic cannula during a laparoscopic procedure. A plurality of surgical tips are operatively connected to respective ones of the shafts at distal ends thereof, while an actuator component is connected to the shafts at a proximal end of the sleeve for independently actuating the operative tips.
