System and method for releasably holding a surgical instrument
First Claim
1. A manipulator assembly comprising:
- a base,an instrument holder removably mounted on the base,a surgical instrument releasably coupled to the instrument holder, anda drive assembly for manipulating the surgical instrument through the instrument holder, and for manipulating the instrument holder relative to the base in at least one degree of freedom;
wherein the surgical instrument comprises;
an elongate shaft with one or more mounting pins laterally extending from the shaft;
the instrument holder comprising a support having a central bore, an axially extending slot for receiving the elongate shaft and the one or more mounting pins of the surgical instrument, and one or more locking slots cut into the support transversely to and in communication with the axial slot so that the one or more mounting pins can be rotated within corresponding of the one or more locking slots when received therein.

Abstract
The invention is directed to a system and method for releasably holding a surgical instrument (14), such as an endoscopic instrument configured for delivery through a small percutaneous penetration in a patient. The instrument comprises an elongate shaft (100) with a pair of mounting pins (116) laterally extending from the shaft between its proximal and distal ends. An instrument holder comprises a support having a central bore (202) and an axially extending slot (204) for receiving the instrument shaft and the mounting pins. A pair of locking slots (206) are cut into the support transversely to and in communication with the axial slot so that the mounting pins can be rotated within the locking slots. The instrument support further includes a latch assembly for automatically locking the mounting pins within the locking slots to releasably couple the instrument to the instrument holder. With this twist-lock motion, the surgeon can rapidly engage and disengage various instruments from the holder during a surgical procedure, such as open surgery, laparoscopy or thoracoscopy.
