  • Patent number: 10292776
    Abstract: A method using a sheathed surgical apparatus includes equalizing a pressure differential between a surgical insufflation gas pressure and an initial pressure lower than the insufflation gas pressure. The insufflation gas pressure is external to a portion of a surgical apparatus upon which a sheath is disposed, and the initial pressure is within the surgical apparatus. The equalizing of the pressure differential occurs via permeation of insufflation gas through the sheath.

  • Publication number: 20170056118
    Abstract: An articulatable member includes a distal end, a proximal end, an actuation member, and a constraint member. The actuation member extends from the proximal end to the distal end. The actuation member transmits force to bend the articulatable member from a neutral position. The constraint member extends from the proximal end to the distal end. The constraint member may have opposite ends that are fixed to the distal end and the proximal end. In one embodiment, the constraint member follows a helical path along at least a portion of the articulatable member from the proximal end to the distal end. In another embodiment, the actuation member follows a helical path along at least a portion of the articulatable member.

  • Publication number: 20160175060
    Abstract: A surgical instrument (203) includes a reusable instrument portion (204) and a disposable tip assembly (205). The disposable tip assembly (205) includes an end effector assembly (206) that in turn includes an end effector. The disposable tip assembly (205) also includes a locking tip cover (410) that locks the disposable tip assembly (205) to a lock interface element (448B) of a tip interface (245) of the reusable instrument portion (204). To facilitate mounting the disposable tip assembly (205) on the tip interface (245) of the reusable instrument portion (204), the disposable tip assembly (205) includes a first quick connect/disconnect element (409) and the tip interface (245) includes a second quick connect/disconnect element (447). The second quick connect/disconnect element (447) is coupled to a tendon (452). The tendon (452) is also coupled to an actuator assembly that provides forces that push and pull (push/pull) the tendon.

  • Patent number: 6464645
    Abstract: A controller for an ultrasonic transducer assembly includes a housing having a longitudinal axis that extends generally parallel to the proximal end of a conduit, such as a catheter. A steering actuator is mounted to the housing for rotation about the longitudinal axis, and a steering hub is mounted for rotation in the housing and coupled to the steering actuator such that rotation of the steering ring with respect to the housing causes rotation of the steering hub. A steering line is secured adjacent the steering hub and extends to the distal end of the conduit such that rotation of the steering hub alters the effective length of the steering line to steer the distal end. The steering line is wrapped at least partially around a stator to avoid threading the steering line through multiple holes and slots prior to termination to the steering hub.
