  • Patent number: 10639055
    Abstract: Methods for treating tissue, and surgical assemblies and related methods are disclosed in which a single input is used to sequentially articulate two members. A medical device includes an input link movable through an input link range of motion, a jaw coupled with the input link, and a tissue manipulation member coupled to the input link and positioned to manipulate a tissue gripped by the jaw. The input link range of motion includes a first portion and a second portion. The input link within the first portion of the input link range of motion drives the jaw through a jaw range of motion. The input link within the second portion of the input link range of motion drives the tissue manipulation member through a tissue manipulation member range of motion.

  • Patent number: 10342625
    Abstract: A telesurgical manipulator comprises an insertion axis mechanism including a base link and a carriage link movable relative to the base link. The carriage link receives a surgical instrument for movement relative to the base link. The base and carriage links are configured for telescoping motion with an extended configuration in which a portion of the carriage link extends beyond the base link. The manipulator also includes an instrument interface included in the carriage link coupled to the surgical instrument via a sterile adaptor that secures a sterile drape to the instrument interface. The sterile drape permits communication between the surgical instrument and the carriage link while maintaining a sterile barrier. The manipulator comprises a communication device on the insertion axis mechanism that wireles sly communicates with the surgical instrument with the sterile drape disposed therebetween and that wirelessly provides power to the surgical instrument with the sterile drape disposed therebetween.

  • Patent number: 9730719
    Abstract: Methods for treating tissue, and surgical assemblies and related methods are disclosed in which a single input is used to sequentially articulate two members. A surgical assembly includes an end effector, a base supporting the end effector, an input link movable relative to the base through a range of motion between a first configuration and a second configuration, and an actuation mechanism. The end effector includes a first articulated member and a second articulated member. The actuation mechanism drivingly couples the input link to the first articulated member within a first portion of the range of motion and drivingly coupling the input link with the second articulated member within a second portion of the range of motion so that a movement of the input link from the first configuration to the second configuration articulates the first articulated member and then articulates the second articulated member.

  • Patent number: 9532849
    Abstract: A robotic surgical system for performing a procedure within a sterile field comprises a manipulator arm and a surgical accessory clamp for coupling a surgical accessory to a distal end portion of the manipulator arm. The accessory clamp includes a base for coupling with the distal end portion of the manipulator arm, two clamp jaws with each of the clamp jaws directly and rotatably coupled to the base by respective pivot pins, and a lever operable to move the two clamp jaws between an open position and closed position. The system also includes a sterile drape covering the accessory clamp and the manipulator arm to shield the accessory clamp and the manipulator arm from the sterile field.
