ABSTRACT:
A laparoscopic instrument assembly with a rigid outer housing, housing multiple guide disks. The guide disks rotate inside the instrument assembly 360 degrees around a center post and guide the rotation, positioning, and implementation of multiple laparoscopic instruments. A plurality of laparoscopic instruments are rotated into position utilizing a selector knob attached to said center post. Once properly positioned, the selected laparoscopic instrument is axially translated into the forward position where it couples to an actuating handpiece. The actuating handpiece engages the selected laparoscopic instrument by pivoting from its disengaged position about a pivot point, thus allowing use of the selected laparoscopic instrument. The instrument can be thus be withdrawn and another instrument selected in the same manner.
