System and method for releasably holding a surgical instrument
First Claim
1. A surgical system comprising:
- a surgical instrument comprising an elongate shaft with proximal and distal ends, a longitudinal axis therebetween, an end effector on the distal end and a mounting interface;
an instrument holder comprising a support having a body with first and second ends and a coupling interface for engaging the mounting interface of the instrument to releasably couple the instrument to the holder;
a locking assembly for locking the instrument to the instrument holder; and
a manipulator assembly including a drive assembly for manipulating the instrument holder and the surgical instrument therewith;
wherein said instrument holder includes first and second links for coupling the drive assembly with the surgical instrument and for transferring at least two motion actuations from the drive assembly to the instrument, the motion actuations including rotation of the instrument about the longitudinal axis and actuation of the end effector.

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.

6. A method for performing a surgical procedure within a sterile field with a robotic surgical system comprising:
-
releasably coupling a sterile surgical instrument to an instrument holder; introducing at least a distal end of the surgical instrument through a percutaneous access port in the patient to a target site within a body cavity of the patient; transferring at least three motion actuations to the instrument from a manipulator assembly through the instrument holder; and withdrawing the surgical instrument from the target site. - View Dependent Claims (7, 8, 9, 10, 11)
