  • Patent number: 11944337
    Abstract: A surgical instrument with improved end-effector gripping force. The instrument comprises a shaft, which may be inserted into a body of a patient. The articulated end-effector is mounted on the distal extremity of the instrument shaft and comprises a plurality of links interconnected by a plurality of joints, whose movements are remotely actuated by the surgeon's hands. This remote actuation is accomplished through mechanical transmission, mainly along flexible elements, which are able to deliver motion from a set of actuation elements, placed at a proximal extremity of the shaft, to the instrument's articulated end-effector. The articulated end-effector further comprises one or more cam-and-follower mechanisms that are able to amplify the force transmitted by the flexible elements so that the actuation force at the instrument jaws is maximized and the tension on the transmission elements minimized, thus increasing the fatigue resistance and life of the instrument.

One or more processors are configured to receive a position command describing a desired position for the end effector, translate the desired position to a command for a joint associated with the end effector, calculate a compensation term to compensate for a source of hysteresis for backlash and/or compliance, and send a motor command for the motor coupled with the actuator based on the compensation term and the command for the end effector.

  • Patent number: 11523860
    Abstract: An electrosurgical medical device that includes a jaw assembly. The jaw assembly includes a first jaw body and a cutting member; and a second jaw body. During a first use state, the medical device is configured to pass a therapy current supplied by a power source between the first jaw body and the second jaw body to electrosurgically effect an anatomical feature. During a second use state, an anatomical feature is electrosurgically effected by contacting the anatomical feature with a medial edge of the cutting member while a second therapy current from the power source is passed between the cutting member and the first jaw body and/or the second jaw body.

  • Patent number: 11426187
    Abstract: The forceps instrument includes a central pull-push member formed by transmission and actuating elements. The central push-pull member opens and closes the branches, and also acts as a tissue abutment that is variable based on the degree of closure of the branches. The variable tissue abutment may be configured as a slider element and is adjustable proportionally to the opening angle of the branches. When grasped, the vessels are brought proximally. The tissue abutment acts as a spacer between the hinge region and the grasped material. While the branches are being closed, the vessel is held stationary and compressed. During compression, expansion of the vessel occurs axially in distal and proximal directions. Due to the receding of the variable tissue abutment during the closing operation, room is created for the grasped material to escape. Tissue accumulations can thus be restricted and overstressing of the tissue can be counteracted.

  • Patent number: 11207129
    Abstract: An end effector assembly adapted to couple to an electrosurgical instrument, the end effector assembly including a plurality of spaced apart small seal plates on opposing jaw members where each seal plate forms a pair of seal plates with the corresponding seal plate on the opposing jaw member. Each pair of seal plates is individually activatable, and the pair of seal plates are activated in sequence. When the opposing jaw members are in an approximated position, the pairs of seal plates around the periphery of each jaw member define a gap therebetween that is larger than the gap between pairs of seal plates along the center of each jaw member.

  • Patent number: 11141180
    Abstract: A gripping mechanism includes: two gripping pieces pivoted relative to each other about a pivot axis; a base supporting the gripping pieces in a pivotable manner; a pulling pulley rotatably supported about a rotation axis parallel to the pivot axis; and a wire wound around the pulley, and causing, with a pulling force, the pulley to move the rotation axis. The pulley is disposed so that a resultant force of tensile forces of the wire becomes greater than the pulling force and generates a moment causing the gripping pieces to be pivoted relative to each other in closing direction. The base includes a first hole. At least one of the gripping pieces includes a second hole inclined in one direction with respect to the longitudinal axis of the first hole. The rotation axis is provided so as to be movable along the longitudinal axes of the individual holes.

  • Patent number: 10993764
    Abstract: A surgical instrument with insulating grips is described. The grips can include internal metal frames that are arranged to limit electrical conductivity within the grips and to other components that attach to a grip, such as a ratchet. The internal metal frames can be constructed of multiple internal portions, spatially separated from one another to interrupt electrical conductivity between the internal portions, but coated with an insulating overmold to provide mechanical coupling between the portions. An internal metal frame can also include a notch, cut-out, or other region partially surrounded by the structure of the internal metal frame, which can be coated with an insulating overmold to define a region of the grip that does not have an internal metal frame therein but which can include an attachment point for mechanically coupling other components while limiting electrical coupling between the metal frame and the other components.
