A surgical instrument includes an end effector assembly including first and second grasping components each defining a tissue-contacting portion. One or both of the first or second grasping components is movable relative to the other between an open position and a closed position. In the closed position, the first and second tissue-contacting portions cooperate to define a grasping area therebetween. One or both of the first or second grasping components is configured to apply energy from the tissue-contacting portion thereof to tissue disposed within the grasping area to treat tissue. The tissue-contacting portion of the first grasping component defines a first opening therethrough. The first opening is disposed within the grasping area and in communication with a first lumen defined at least partially through the first grasping component. The first lumen is adapted to connect to a source of vacuum to enable aspiration through the first opening.

A method of compressing tissue during a surgical procedure is disclosed. The method comprises obtaining a surgical instrument comprising an end effector, wherein the end effector comprises a first jaw and a second jaw, establishing a communication pathway between the surgical instrument and a surgical hub, and inserting the surgical instrument into a surgical site. The method further comprises compressing tissue between the first jaw and the second jaw, determining a location of the compressed tissue with respect to at least one of the first jaw and the second jaw, communicating the determined location of the compressed tissue to the surgical hub, and displaying the determined location of the compressed tissue on a visual feedback device.

An ergonomic attachment system for connecting an irrigation tube or an aspiration tube to a surgical handpiece that reduces surgeon wrist fatigue due to tubing twist. The tube is connected to the handpiece through a swivel joint which allows the tube to rotate circumferentially with respect to the handpiece and self-adjust to a neutral position to relieve the twist.

Systems, instruments, and methods for minimally invasive procedures including one or more of fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision are described. Embodiments include instrumentation comprising a scalpet assembly coupled to a carrier, and the scalpet assembly includes a scalpet array. The scalpet array includes one or more scalpets configured for fractional resection, fractional lipectomy, fractional skin grafting, and/or fractional scar revision. The system includes a vacuum component coupled to the scalpet assembly and configured to evacuate tissue from the a site. The carrier is configured to control application of a rotational force and/or a vacuum force to the scalpet assembly.

Systems, instruments, and methods are described in which an apparatus comprises a housing including a scalpet device. The scalpet device includes a scalpet array that includes scalpets arranged in a pattern. The scalpets are deployable from the housing to generate incised skin pixels at a target site. The housing is positioned and the scalpet array is deployed into tissue at the target site. Incised skin pixels are generated when the target site is a donor site, and skin defects are generated when the target site is a recipient site. The incised skin pixels are harvested.

Various systems and methods for determining the composition of tissue via an ultrasonic surgical instrument are disclosed. A control circuit can be configured to monitor the change in resonant frequency of an ultrasonic electromechanical system of the ultrasonic surgical instrument as the ultrasonic blade oscillates against a tissue and determine the composition of the tissue accordingly. In some aspects, the control circuit can be configured to modify the operation of the ultrasonic electromechanical system or other operational parameters of the ultrasonic surgical instrument according to the detected tissue composition.

A method for characterizing a state of an end effector of an ultrasonic device is disclosed. The ultrasonic device including an electromechanical ultrasonic system defined by a predetermined resonant frequency. The electromechanical ultrasonic system further including an ultrasonic transducer coupled to an ultrasonic blade. The method including applying, by an energy source, a power level to the ultrasonic transducer, measuring, by a control circuit coupled to a memory, an impedance value of the ultrasonic transducer, comparing, by the control circuit, the impedance value to a reference impedance value stored in the memory; classifying, by the control circuit, the impedance value based on the comparison; characterizing, by the control circuit, the state of the electromechanical ultrasonic system based on the classification of the impedance value; and adjusting, by the control circuit, the power level applied to the ultrasonic transducer based on the characterization of the state of the end effector.

Probes for delivering ultrasonic energy and related methods. The probe includes a shank having a shaft coupling a proximal end to a distal end. The shank is configured to propagate ultrasonic energy from the proximal end to a tip of the distal end in a propagation direction parallel to a longitudinal axis disposed along a centerline of the shank. The tip may be positioned to substantially coincide with a displacement antinode position when the ultrasonic energy corresponds to odd integer multiples of a quarter wavelength of a resonance frequency. Multiple grooves within the shaft are configured to create multiple cavitation volumes in a medium proximate to the shank responsive to the ultrasonic energy. The multiple grooves include a second groove intervening between a first groove and the proximal end. The first groove is positioned at a distance of an integer multiple of a half-wavelength of the resonance frequency.

Surgical systems can include evacuation systems for evacuating smoke, fluid, and/or particulates from a surgical site. A surgical evacuation system can be intelligent and may include one or more sensors for detecting one or more properties of the surgical system, evacuation system, surgical procedure, surgical site, and/or patient tissue, for example.

A surgical system is disclosed including an end effector, a control circuit, a closure member, and a firing member. The end effector includes a first jaw, a second jaw, and an electrode. The first jaw is rotatable relative to the second jaw between an open position and a close position to capture tissue therebetween. The electrode is configured to conduct a sub-therapeutic RF current to the tissue. The control circuit is operably coupled to the electrode. The control circuit is configured to measure impedance of the tissue over time based on the sub-therapeutic RF current. The closure member is configured to move the first jaw towards the second jaw at a closure rate based on the impedance of the tissue. The firing member is configured to move within the end effectors towards a fired position at a firing rate based on the impedance of the tissue.
