  • Patent number: 10537358
    Abstract: A sterile drape, a surgical system with the drape, and a draping method are provided. In one embodiment, a sterile drape includes a plurality of drape pockets, each of the drape pockets including an exterior surface to be adjacent a sterile field for performing a surgical procedure and an interior surface to be adjacent a non-sterile instrument manipulator coupled to a manipulator arm of a robotic surgical system. The drape further includes a plurality of flexible membranes at a distal face of each of the drape pockets for interfacing between outputs of an instrument manipulator and inputs of a respective surgical instrument, and a rotatable seal adapted to couple a proximal opening of each of the drape pockets to a rotatable element at a distal end of the manipulator arm.

  • Publication number: 20200000490
    Abstract: A drape includes a first drape portion configured to receive a manipulator arm of a surgical system and a pocket coupled to a distal portion of the first drape portion. The pocket is configured to receive a manipulator of the surgical system. The pocket includes a flexible membrane positionable between an output of the manipulator and an input of a surgical instrument mountable to the manipulator. In some embodiments, the flexible membrane is located at a distal end of the pocket. In some embodiments, the flexible membrane is configured to allow an actuating force to be transmitted from the output of the manipulator to the input of the surgical instrument. In some embodiments, the pocket provides a sterile barrier between the manipulator and the surgical instrument. In some embodiments, the drape further includes a rotatable seal configured to couple a proximal opening of the pocket to the first drape portion.

  • Publication number: 20190314096
    Abstract: A controller in a computer-assisted teleoperated surgical system automatically moves a part of the system, in response to a user tapping the part, to facilitate draping of that part. This speeds the draping process and diminishes the likelihood that the sterile surgical drape is damaged or contaminated during the draping of that part of the system.

  • Publication number: 20190298469
    Abstract: A sterile surgical drape includes at least one assembly for managing and retaining sterile surgical drape on a part of a computer-assisted surgical system. For example, an assembly for managing and retaining sterile surgical drape is used to configure the surgical drape on a portion of the computer-assisted surgical system so that the sterility of sterile portions of the surgical drape is not compromised, and so that the physical integrity of the surgical drape is not compromised. Any one of a hinged cinch assembly, a hinged cinch and attachment element assembly, and an alignment and attachment element assembly, or any combination of the hinged cinch assembly, the hinged cinch and attachment element assembly, and the alignment and attachment element assembly can be attached to a surgical drape.

  • Publication number: 20190223969
    Abstract: A surgical system includes an insertion assembly and a drape shroud assembly mounted on the insertion assembly. When a sleeve of a surgical drape draping the insertion assembly is fastened to the drape shroud assembly, the sleeve is divided into two pockets. Instead of managing one long tube, the management problem of the drape sleeve is reduced to managing a plurality of shorter tubes. Shorter tubes make it easier for excess sleeve material to accordion as the tube length shortens instead of possibly bowing out and contacting a part of the insertion assembly or some other part of the surgical system.
