Abstract
A surgical drape for providing a localized instrument sterility barrier includes: a tube having a proximal end and a distal end, the tube defining an interior bore sized to receive an elongated shaft of a surgical instrument; and a port coupler at the distal end of the tube, the port coupler configured to couple the distal end of the tube to a surgical port through which the elongated shaft extends. The tube is collapsible to accommodate relative movement between the instrument and the surgical port during a surgical procedure.
Claims16
A surgical system comprising:
- a manipulator comprising an instrument support member;
- an instrument carriage movably mounted the instrument support member, the instrument carriage movable along at least a portion of the instrument support member, wherein the instrument carriage is configured to receive a surgical instrument comprising a shaft;
- an entry guide mounted to the instrument support member and positioned relative to the instrument carriage to receive the shaft;
- and
- a surgical drape comprising a tube defining an interior bore sized to receive the shaft of the surgical instrument, the surgical drape mountable relative to the surgical instrument such that the surgical drape extends from the instrument carriage, along at least part of the shaft of the surgical instrument, to the entry guide,
- wherein the surgical drape comprises a base coupler at a first end portion of the tube, the base coupler configured to couple with the instrument carriage to form a proximal seal;
- wherein the surgical drape comprises a port coupler at a second end portion of the tube, the port coupler configured to couple with the entry guide, the port coupler comprising a self- sealing element that resiliently seals the second end portion of the tube while uncoupled from the entry guide, the entry guide configured to open the self-sealing element and form a distal seal between the self-sealing element and the entry guide.

A surgical system comprising:
- an instrument assembly comprising:
- a surgical instrument comprising a shaft;
- and
- an instrument carriage configured to receive the surgical instrument;
- an entry guide mounted positioned relative to the instrument carriage to receive the shaft;
- and
- a surgical drape comprising a tube defining an interior bore sized to receive the shaft of the surgical instrument, the surgical drape configured to couple to the instrument assembly such that the surgical drape extends along an entire exposed length of the shaft of the surgical instrument to the entry guide,
