A surgical instrument can comprise a handle, a motor, and a shaft extending from the handle. The handle and/or the shaft can define a longitudinal axis. The surgical instrument can further comprise a fastener cartridge comprising a plurality of fasteners removably stored therein, an anvil configured to deform the fasteners, a closure drive configured to move the anvil toward and away from the fastener cartridge which is rotatable about the longitudinal axis, and a firing drive configured to deploy the fasteners from the fastener cartridge which is rotatable about the longitudinal axis. The surgical instrument can further comprise a transmission comprising a first operating configuration which connects the motor to the closure drive and a second operating configuration which connects the motor to the firing drive.

Disclosed herein are apparatuses, systems, kits, and methods for treating skin, such as skin tightening or for treating diseases, disorders, and conditions that would benefit from tissue area or volume reduction, skin restoration, skin tightening, skin lifting, and/or skin repositioning and/or for generally improving skin function or appearance (e.g., the removal of unwanted skin features or irregularities such as sebaceous glands, sweat glands, hair follicles, necrosis, and fibrosis). Such apparatuses, systems, kits, and methods comprise an apparatus having a handheld main body and a detachably attachable tip comprising one or more needles.

The invention comprises a system, method, and apparatus for securing two ends of a ruptured or partially ruptured tendon in the hand or wrist during a repair, recession, or revision procedure. During this tenorrhaphy, anchoring material is inserted into the proximal ruptured surface of the tendon by an apparatus comprising multiple needles of at least two different types. Connecting material spans the site of tenorrhaphy of a ruptured tendon, or a multiplicity of ruptured tendons. In some embodiments, interlocking patterns of loop and helical suture are inserted by straight and helical needles, respectively.

Systems and methods discussed herein relate to surgical systems including tissue resecting devices where the handset has a disposable portion detachably coupled to a reusable portion. The reusable portion may be a housing where a motor and electronics are stored that may be used to drive a shaft inserted into the disposable portion. The shaft may be coupled to a fluid pathway through the disposable portion that is fluidly isolated from the reusable section. After use, the disposable section is detached from the reusable section and disposed, and the reusable section may be cleaned and sterilized, or may be cleaned only.

A surgical assembly comprising a distal connector portion, a stapling assembly, and a sensor is disclosed. The stapling assembly comprises an end effector and a proximal connector portion configured to releasably connect to the distal connector portion. The end effector comprises an anvil and an elongate channel adapted to receive a staple cartridge. At least one of the anvil and the elongate channel is movable to a clamped configuration. The proximal connector portion comprises first bayonet-mount lugs and second bayonet-mount lugs. The sensor is configured to detect connections by the proximal connector portion. The surgical assembly further comprises an end-of-life indicator for the stapling assembly based on connections by the proximal connector portion.

A utility tool device including a handle with a tool recess and a lever arm recess; a rotatable lever arm with a magnet that is configured to fit in the lever arm recess; and a rotatable lever hinge attached to the lever arm and configured to attach to a tool; wherein the tool recess is configured to have a tool fit in the tool recess; and wherein the magnet is configured to lock a tool in place when the lever arm is in the lever arm recess.

A surgical instrument is configured to consist of two separable parts. The first part includes a disposable end effector unit, including an electrosurgical end effector and mechanical drive componentry. The second part includes a reusable electronics unit, containing the RF electronic circuitry of the instrument. A user-releasable complementary interface is provided on each part, allowing the parts to be connected in use. Providing a division of components in this manner improves the sterility of the device, providing easier cleaning of the reusable part of the instrument.

An ultrasonic device may include an electromechanical ultrasonic system defined by a predetermined resonant frequency and include an ultrasonic transducer coupled to an ultrasonic blade. A method of delivering energy to the device may include applying energy to the blade at a first power level via the transducer coupled to the blade, measuring a complex impedance of the transducer, receiving a complex impedance feedback data point, comparing the complex impedance feedback data point to a reference complex impedance characteristic pattern, and determining that the blade is contacting a vessel based on the comparison. The method may also include disabling the power applied to the transducer and switching to a lower power level. The method may further include generating a warning that the blade is contacting a vessel, such as a light or a sound. An ultrasonic surgical instrument may effect the method.

A hand-held surgical instrument includes a handle housing, an elongated shaft portion configured to extend distally relative to the handle housing, and a surgical end effector configured to be coupled to a distal end portion of the shaft portion. An articulation screw is operably coupled to the surgical end effector, and an articulation nut is disposed about and operably coupled to the articulation screw. The articulation screw is configured to translate in response to a rotation of the articulation nut, whereby the articulation screw articulates the surgical end effector between a parallel orientation relative to the shaft portion and a non-parallel orientation relative to the shaft portion.

Embodiments of the present disclosure provide a method and apparatus for sensing. An exemplary apparatus includes a surgical device, a control unit comprising a user interface, a power unit, a motor, a warning element, a processor, and a memory including computer program instructions, the user interface operable to select between an on or off setting for the apparatus, the power unit operable to connect with a power source. The apparatus further includes a sensor located on at least one of the surgical device and the control unit, the sensor operable to sense a presence of gases, and a conduit comprising a vacuum tube fluidly coupled to the surgical device and the control unit, and a communication line operable to transmit electronic signals between the surgical device, the control unit and the sensor.
