Embodiments of the present invention provide an improved surgical instrument having an end effector mounted on the end of an elongate shaft extending from a handle. The end-effector is capable of several different operations, including grasping, cutting, and sealing and/or coagulating tissue, and one of the operations is controlled by a trigger mechanism contained within the handle. In some embodiments, the end effector includes a pair of curved jaw members and a blade assembly having a cutting blade at its distal end. The trigger mechanism is arranged to drive the blade assembly longitudinally within the elongate shaft such that the cutting blade protrudes between the jaw members. In order to help the trigger mechanism push the blade assembly around the curved jaws, the distal end of the blade has a graduated flexibility such that it can more easily bend to the shape of the jaw members. The distal end of the blade may also be provided with a low friction coating so that it can more easily slide between the jaw members.

A surgical instrument, system and method for adjusting a compression force applied by a surgical instrument are disclosed. The method includes determining tissue impedance of tissue in contact with an end effector of the surgical instrument, determining a tissue type based on the tissue impedance, selecting a first energy modality to deliver to the surgical instrument, generating a first signal waveform based on the first energy modality, selecting a second energy modality to deliver to the surgical instrument, generating a second signal waveform based on the second energy modality, outputting the first and second signal waveform to deliver energy to the end effector, and adjusting a compression force applied by the end effector by changing a size of a gap between the tissue and the clamp arm based on a proportion of the first signal waveform to the second signal waveform.

A medical instrument having an aspiration needle, handle device and an actuation force limiter. The actuation force limiter provides an active or passive force release mechanism that keeps the force from overpowering operation of the needle.

A cervical cup includes a body having a flange and a vacuum port so that application of a vacuum to the port will secure the cervical cup to a cervix disposed inside of the body of the cup. Example of the disclosed methodology to treat preterm birth includes inserting of a cervix into a cervical cup and applying a vacuum to a vacuum port of the cervical cup so as to secure the cervical cup to the cervix.

Methods for resetting a fuse in a surgical instrument are disclosed.

A surgical device comprising a housing, a shaft extending from the housing, an end effector extending from the shaft, a feeder drive, a rotatable clip magazine, and a rotary input is disclosed. The shaft defines a shaft axis and comprises a feeding chamber. The feeder drive is configured to move between a proximal position and a distal position relative the shaft. The rotatable clip magazine is configured to rotate about the shaft axis. The rotary input is selectively engageable with the feeder drive and the rotatable clip magazine. The rotary input is configured to be engaged with the feeder drive and the rotatable clip magazine to consecutively feed a clip from and deliver a clip to the feeding chamber.

A surgical device for clipping tissue is disclosed. The surgical device comprises a housing, a shaft extending from the housing, an end effector extending from the shaft, a motor, a rotary input configured to rotate in response to the motor, and a clip magazine comprising a plurality of clips. The shaft defines a shaft axis. The clip magazine is operably connected to the rotary input. The clip magazine is movable in a first direction through a clip feed stroke in response to the rotation of the rotary input. The clip magazine is movable in a second direction in response to the rotation of the rotary input. The second direction is transverse to the first direction.

A detachable motor pack, for use with multiple electrical surgical instruments, includes a housing; a plurality of motors retained within the housing; a controller configured to control one or more operations of the plurality of motors; a first interface portion, wherein the first interface portion is configured to releasably attach to a hand-held surgical instrument and to a robotic surgical instrument; and a second interface portion, wherein the second interface portion is configured to releasably attach to a first surgical tool of the hand-held surgical instrument and to a second surgical tool of the robotic surgical instrument.

A surgical device for clipping tissue is disclosed. The surgical device comprises a housing, a shaft defining a shaft axis, and an end effector. The end effector comprises a first jaw, a second jaw, and a receiver. The first jaw and the second jaw are movable relative to each other between an open position and a closed position. The receiver is at least partially defined between said first jaw and said second jaw. The surgical device further comprises a rotatable clip magazine configured to rotate about the shaft axis, a first advancing system, and a second advancing system. The clip magazine is configured to store at least two clips. The second advancing system is configured to operate sequentially with the first advancing system. The first advancing system and the second advancing system are configured to sequentially advance the clips into the receiver of the end effector.

A method and device for controlling the compression of tissue include clamping tissue between a first clamping member and a second clamping member by driving at least one of the clamping members with an electric motor toward a predetermined tissue gap between the clamping members and, during the clamping, monitoring a parameter of the electric motor indicative of a clamping force exerted to the tissue by the clamping members. The method and device include, during the clamping, controlling the electric motor, based on the monitored parameter, to limit the clamping force to a predetermined maximum limit.
