    Abstract: Embodiments of the disclosed technology relate to a bipolar electrosurgical device for a laparoscopic environment, as well as methods for the use of such a device. Embodiments of the device may include a set of opposing jaws comprising at least one bipolar electrode pair disposed thereon, the set of jaws configured to deliver radiofrequency energy to a target tissue. Embodiments of the set of jaws, when closed, may have a diameter no greater than about 5 mm. The device may further include a shaft with a diameter that may be no greater than about 5 mm. Each of the jaws has a tissue-facing surface of each jaw that may include a complementary self-aligning configuration with respect to the longitudinal axis of the other jaw. Embodiments of the device may further include a pinless rotation assembly formed from rotatably cooperative features of the first jaw and the second jaw that connect the jaws together and enable the jaw set to pivot between an open position and a closed position.

  • Patent number: 11000330
    Abstract: A bipolar electrosurgical instrument includes first and second shafts each having a jaw member extending from its distal end. Each jaw member is adapted to connect to a source of electrosurgical energy such that the jaw members are capable of selectively conducting energy through tissue held therebetween. A knife channel is configured to reciprocate a cutting mechanism therealong. An actuator selectively advances the cutting mechanism. A switch is disposed on the first shaft and is configured to be depressed between a first position and at least one subsequent position upon biasing engagement with a mechanical interface disposed on the second shaft. The first position of the switch relays information to the user corresponding to a desired pressure on tissue and the at least one subsequent position is configured to activate the source of electrosurgical energy to supply electrosurgical energy to the jaw members.

  • Patent number: 8945175
    Abstract: A latch mechanism for a surgical instrument includes a lever moveable from an initial position to an actuated position for moving an end effector assembly from a first to a second state. A pin extends from the lever. A cantilever spring is operably engaged to the housing of the instrument. A pin track member is operably engaged to the cantilever spring at a free end thereof. The pin track member is configured to permit translation of the pin therealong between a first position corresponding to the initial position of the lever and a second position corresponding to the actuated position of the lever. The pin is configured to translate from the first to the second position along a first path and from the second position back to the first position along a second path and is configured to be releasably retained in the second position.

  • Patent number: 8936614
    Abstract: A surgical instrument includes a housing supporting first and second actuators thereon, and an elongated shaft extending distally from the housing. First and second drive members extend through the elongated shaft to operatively couple respective actuators to respective jaw members such that independent manipulation of one of the actuators may induce pivotal movement of an individual jaw member. A locking member is operatively associated with the first and second drive members, and is selectively movable between locked and unlocked positions. When the locking member is in the locked position, the first and second drive members are coupled to one another and move concurrently to drive the jaw members in a bilateral manner. When the locking member is in the unlocked position, the drive members are decoupled from one another and move independently to permit operation of the instrument in a unilateral manner.

  • Patent number: 8870912
    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: 8845667
    Abstract: A surgical tool such as a grasper or a pair of surgical scissors includes a hinge portion that spans between a handle proximal portion and a distal working portion to communicate mechanical actions of the handle proximal portion to the distal working portion. A programmable rotary module is coupled to the hinge portion and includes a sensor, an actuator, and a controller. The sensor, actuator, and controller may be enclosed in a common housing. The sensor measures rotation of the distal working portion and the actuator generates haptic effects to the proximal handle portion. A controller is electrically connected to the sensor and to the actuator. The controller receives the rotation measurements from the sensor and, based upon the rotation measurements, outputs a control signal to the actuator relating to the generation of haptic effects. The haptic effects may include force sensations such as detents and barriers.
