  • Patent number: 10765470
    Abstract: Various forms are directed to systems and methods for dissection and coagulation of tissue. A surgical instrument includes an end effector configured to dissect and seal tissue at a distal end thereof, and a generator that is electrically coupled to the surgical instrument and that is configured to deliver energy to the end effector. The surgical instrument includes an end effector configured to interact with a tissue at a distal end thereof, a generator electrically coupled to the surgical instrument and configured to deliver radio frequency (RF) energy and ultrasonic energy to the end effector to allow the end effector to interact with the tissue. The energy delivered to the end effector switches between RF energy and ultrasonic energy based on a determination of various factors such as tissue impedance.

  • Publication number: 20190008543
    Abstract: A variety of methods for managing a re-usable ultrasonic medical device may include a medical device control module capable of receiving functional data from a user assembled or reassembled ultrasonic medical device, and notifying the user if a value of the functional data lies within an acceptance range. If the value of the functional data does not lie within the acceptance range, the control module may prompt a user to reassemble the device or to clean or replace one or more components thereof. The functional data may relate to a clamp force of a jaw assembly, an impedance or resonant frequency value of an ultrasonic blade, or a mechanical displacement value of one or more moving components of the device.

  • Publication number: 20180333182
    Abstract: An ultrasonic surgical instrument and method for identifying tissue state and energizing the surgical instrument includes an end effector having an ultrasonic blade and an RF electrode, a shaft assembly, a body, and a power controller. A first ultrasonic energy input is configured to be actuated from a first unactuated energy input state to a first actuated energy input state. A trigger input is configured to be actuated from an unactuated trigger input state to an actuated trigger input state. The power controller is operatively connected to the ultrasonic blade, the RF electrode, the first ultrasonic energy input, and the trigger input and configured to direct at least one of the ultrasonic blade or the RF electrode to be selectively driven according to a predetermined drive function based on the tissue impedance, the state of the first energy input, and the state of the trigger input.

  • Publication number: 20180235691
    Abstract: A surgical system includes a module for compiling a plurality of operational parameters of the surgical system during a plurality of treatment cycles performed by the surgical system. The module includes a processor and a memory unit, the processor configured to store in the memory unit values of the plurality of operational parameters associated with each of the plurality of treatment cycles, wherein the processor is configured to identify a subset of the stored values of the plurality of operational parameters temporally proximate to an intervening event.

  • Patent number: 10004528
    Abstract: An apparatus comprises a body, a shaft assembly, and an end effector. The shaft assembly extends distally from the body. The end effector is located at a distal end of the shaft assembly. The end effector comprises an ultrasonic blade, a clamp arm, and a sleeve. The ultrasonic blade is configured to vibrate at an ultrasonic frequency. The clamp arm is configured to move toward the ultrasonic blade. The sleeve extends along at least part of the length of an outer portion of the ultrasonic blade or the clamp arm. The sleeve is configured to prevent tissue from contacting a portion of the ultrasonic blade or clamp arm covered by the sleeve.

  • Publication number: 20180146976
    Abstract: Methods and apparatus for end effector control and calibration are described. The method may include detecting a signal in response to movement of a first tube relative to a second tube, the first tube driving movement of a clamp arm of the end effector. The method may further include determining a clamp arm position of the end effector relative to a ultrasonic blade of the end effector based on the signal. The method may also include adjusting a power output to the ultrasonic blade of the end effector based on the clamp arm position.

  • Publication number: 20180078268
    Abstract: Various ultrasonic instruments are disclosed. The ultrasonic instruments include structures configured to indicate the cutting length of the instruments, detect when grasped tissue has extended beyond the cutting length of the instrument, and prevent tissue from extending beyond the cutting length. Several techniques for each types of structures are disclosed.

  • Publication number: 20170105754
    Abstract: A surgical instrument includes a body, an ultrasonic blade, a clamp arm, and a resilient member. The body includes an electrical conductor and defines a longitudinal axis. The clamp arm is pivotably coupled with the body at a pivot assembly. The clamp arm is operable to compress tissue against the ultrasonic blade. The clamp arm includes an electrode operable to apply RF energy to tissue, wherein the clamp arm is configured to be loaded onto and removed from the body at the pivot assembly along a path that is transverse to the longitudinal axis defined by the body. The resilient member is located within the pivot assembly. The resilient member is configured to provide electrical continuity between the electrode of the clamp arm and the electrical conductor of the body.

  • Patent number: 9386984
    Abstract: A retainer for use with a fastener cartridge that is locked to the fastener cartridge until the fastener cartridge is inserted into a fastener cartridge channel of a surgical fastener. The retainer can include one or more deflectable tabs that engage the fastener cartridge. The one or more tabs can be displaced when the fastener cartridge is fully installed in the fastener cartridge channel such that the tabs disengage from the fastener cartridge, enabling a user to remove the retainer. In certain embodiments, tabs can extend from a body of the retainer and can engage exterior portions of a fastener cartridge. The tabs can be displaced outwardly by the fastener cartridge channel. In certain embodiments, tabs can extend from one or more movable portions that engage a slot in the fastener cartridge. The tabs can be displaced inwardly when the movable portions are deflected by the fastener cartridge channel.
