System and method for releasably holding a surgical instrument
First Claim
1. A surgical system comprising:
- a surgical instrument assembly including an instrument having an elongate member with a proximal end, a distal end, a longitudinal centerline therebetween and an end effector coupled to the distal end, and including an instrument holder supporting the instrument, the instrument holder comprising a least two of engageable drive coupling elements;
at least the distal end and end effector of the surgical instrument being sterilizable and configured to be insertable through a percutaneous incision in the body of the patient to a target site within to body; and
a manipulator assembly including a actuator drive for manipulating the instrument holder and the surgical instrument therewith, the actuator drive configured to removably couple to the engageable coupling elements of the instrument holder of the instrument assembly so as to transfer at least two motion actuations from the actuator drive to the instrument.

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.
