Cutting Patents (Class 600/564)
  • Patent number: 11589851
    Abstract: A biopsy forceps device includes a tension member and an end effector including first and second jaws movable between an open configuration, in which the jaws are separated from one another to receive target tissue therebetween, and a closed configuration, in which cutting edges of the jaws are moved toward one another to cut a portion of the target tissue. The jaws define a tissue receiving space therebetween to house the cut tissue. The jaws are pivotable relative to one another, each of the jaws including a serrated cutting edge extending therealong, the end effector further including a tension member attachment including a proximal end coupled to the tension member. The attachment is movably coupled to the jaws so that distal movement of the attachment moves the jaws to the open configuration while proximal movement thereof moves the jaws to the closed configuration.

  • Patent number: 11207500
    Abstract: A needle steering system and apparatus provides active, semi-autonomous control of needle insertion paths while still enabling a clinician ultimate control over needle insertion. A method and system controls the needle path as the needle is inserted by precisely controlling the rotation of the needle as it continuously rotates during insertion. This enables underactuated 2 degree-of-freedom (DOF) control of the direction and the curvature of the needle from a single rotary actuator. Control of the rotary motion is therefore decoupled from the needle insertion. The rotary motion controls steering effort and direction, while the insertion controls needle depth or insertion speed. In one implementation, the proposed method does not require constant velocity insertion, interleaved insertion and rotation, or known insertion position or speed. The insertion may be provided by a robot or other automated method, may be a manual insertion, or may be a teleoperated insertion.

  • Patent number: 11147689
    Abstract: An acetabular cup remover with a blade for removing tissue adjacent an acetabular cup. The blade is oscillated against an arcuate section of tissue. Once a section of tissue is cut, an indexing assembly rotates the blade. The blade is again oscillated to cut a new arcuate section of tissue.

  • Patent number: 11129686
    Abstract: A robotic surgical instrument comprising a shaft, a first end effector element, an articulation connecting the first end effector element to a distal end of the shaft, the first end effector element being movable relative to the articulation, and a drive mechanism at a proximal end of the shaft. The drive mechanism comprises a first actuator connected to the first end effector element by a first pair of driving elements. The first pair of driving elements are configured such that a tension force applied by the first actuator to a first one of the first pair of driving elements causes the first end effector element to move relative to the articulation in a first motion direction, and the tension force applied to a second one of the first pair of driving elements causes the first end effector element to move relative to the articulation in a second motion direction.

  • Patent number: 11083482
    Abstract: A method of performing a procedure on a meniscus, via an ultrasonic surgical tool. The ultrasonic tool includes a probe capable of transmitting ultrasonic vibration from a proximal end toward a front end. The probe includes a bent portion that is inclined with respect to a longitudinal axis of the probe, and a procedure portion that is disposed at the front end of the probe and has a plurality of cutting surfaces. The method includes: inserting the probe in a body; moving the probe through a space in between the femur and the tibia to position the procedure portion adjacent to the horizontal rupture in the meniscus; positioning a cutting surface of the procedure portion on a posterior portion of the meniscus; and resecting the horizontal rupture along an inclination of the meniscus to form an inclined resection plane.

  • Patent number: 11083510
    Abstract: The surgical wire twisting tool includes a hollow housing, a plunger, a rotating member, a jaw actuating rod and a hollow cylindrical guide. A portion of the plunger is received within a second end of the hollow housing, and the rotating member is received within the hollow housing, such that a portion of the rotating member projects through a first end of the hollow housing. A pair of jaws are mounted on one end of the jaw actuating rod. The hollow cylindrical guide is received within the hollow housing, such that the other end of the jaw actuating rod projects through a second end of the rotating member and into the hollow cylindrical guide. The plunger slides through a second end of the hollow cylindrical guide to drive movement of the jaw actuating rod. The pair of jaws may be rotated with respect to the hollow housing, and also locked.
