A surgical fastener applier having a housing containing a compartment therein, an elongated member extending distally from the housing and first and second jaws. A firing mechanism is positioned within the housing movable to a second position to effect firing of fasteners. A power pack is removably loadable into the compartment, the power pack having one or both of a) a first motor and a first engagement member removably engageable with the firing mechanism when the power pack is loaded into the compartment to effect movement of the firing mechanism; and b) a second motor and a second engagement member removably engageable with an articulating mechanism in the housing of the surgical fastener applier to effect movement of an articulation mechanism to effect articulation. One or both of a firing position and an articulation position are tracked during the surgical procedure. Sensors are provided to detect select parameters and instrument functions.

An end effector assembly of a tissue-resecting device includes an outer shaft defining a window, a drive wire extending through the outer shaft, and a distal cutting tip disposed within the outer shaft. The drive wire includes a cylindrical body and a distal end portion defining a semi-cylindrical configuration including a semi-cylindrical bottom surface and a planar top surface having a semi-cylindrical cut-out defined therein. The distal cutting tip at least partially overlaps the window and has a semi-cylindrical lumen defined by a semi-cylindrical bottom surface and an open top. The distal end portion of the drive wire is at least partially received and within the semi-cylindrical lumen with the semi-cylindrical surfaces substantially mating. The drive wire is configured to drive rotation or oscillation of the distal cutting tip relative to the outer shaft.

The present disclosure relates to trocar-cannula insertion tools for ophthalmic procedures. In certain embodiments, a cap for a trocar-cannula insertion tool includes a body having a proximal end and a distal end opposite the proximal end. A marking element extends in a distal direction from the distal end of the body and includes at least one marking tip for forming one or more indentations on a patient's eye during an ophthalmic procedure. A manipulation element extends from the body in a direction different from the marking element and includes at least one manipulation tip for gripping a tissue of the patient's eye during the ophthalmic procedure. In certain embodiments, the cap further includes at least one window for exposing a photoluminescent cannula of the trocar-cannula insertion tool to light, enabling the cannula to absorb photons prior to insertion thereof.

An optical obturator apparatus includes an obturator sleeve defining a longitudinal axis and having a longitudinal bore for receiving surgical instrumentation and a transparent window mounted to the obturator sleeve and being dimensioned and configured to pass through tissue. The transparent window is mounted for movement between a first position in general alignment with the longitudinal axis of the obturator sleeve and a second position radially displaced from the longitudinal axis to thereby expose the longitudinal bore of the obturator sleeve to permit passage of the surgical instrumentation. The transparent window may include a cutting blade, or alternatively two cutting blades, adapted to penetrate tissue.

A computer-assisted teleoperated system includes a pre-load assembly in an instrument manipulator that is under the control of a controller. The controller can automatically cause the preload assembly to engage and disengage a preload. A surgical apparatus includes an instrument manipulator assembly and a sterile adapter assembly. The sterile adapter assembly is mounted in the distal face of the instrument manipulator assembly. When the preload assembly configures the instrument manipulator assembly to apply a preload force on the sterile adapter assembly, the sterile adapter assembly is removable from the distal face of the instrument manipulator. The sterile adapter assembly includes a mechanical sterile adapter assembly removal lockout and a mechanical instrument removal lockout.

A surgical cutting and stapling end effector. Various embodiments comprise a channel that is configured to operably support a removable staple cartridge. A rotary end effector drive shaft is supported within the channel and is configured to move a firing assembly longitudinally within the end effector to cause the sled to eject surgical staples from the staple cartridge. The firing assembly is prevented from moving distally through the channel unless a surgical staple cartridge that has a sled in a starting position has been seated within the channel.

A surgical apparatus comprises a body, an ultrasonic transducer, a shaft, an acoustic waveguide, an articulation section, an end effector, and an articulation drive assembly. The ultrasonic transducer is operable to convert electrical power into ultrasonic vibrations. The shaft couples the end effector and the body together. The acoustic waveguide is coupled with the transducer. The articulation section includes a collar that is located distal to a nodal portion of the waveguide and is operable to deflect the end effector away from the longitudinal axis. The end effector comprises an ultrasonic blade in acoustic communication with the ultrasonic transducer. The articulation drive assembly is operable to drive articulation of the articulation section. The articulation drive assembly comprises at least one translating articulation driver coupled with the collar. The ultrasonic blade is operable to deliver ultrasonic vibrations to tissue even when the articulation section is in an articulated state.

A handle for a surgical tool including a shaft having a proximal end and a distal end with a gripping handle affixed to the proximal end of the shaft. A bushing is attached to the distal end of the shaft, the bushing including a plurality of flexible members circumferentially spaced apart. The handle further includes a sleeve circumscribing the shaft and the bushing. The sleeve is moveable between a first position substantially covering an entirety of the bushing and a second position spaced from a most distal end of the bushing.

An apparatus is provided for stapling tissue. The apparatus includes an anvil and a trocar selectively coupled with the anvil. The anvil may have an inner opening and a plurality of staple pockets aligned around a surface of the anvil. The anvil may be inserted trans-orally through an esophagus prior to being coupled with the trocar. The trocar may include a shaft and a locking assembly. The locking assembly may secure the anvil in position relative to the trocar when the locking assembly is in the expanded position. The apparatus may also include an alignment assembly to align the staple pockets of the anvil relative to the apparatus. The apparatus may also include an introduction assembly to guide the anvil through the esophagus.

A surgical instrument comprising a shaft, an end effector, a housing, a drive assembly, and a manually-driven actuator is disclosed. The end effector comprises a first jaw and a second jaw rotatable relative to the first jaw between an open position and a clamped position. The housing comprises a rotary input movable by a motor. The drive assembly is operably engaged with the rotary input. The drive assembly is movable by the motor in a motorized mode of operation to transition the second jaw toward the clamped position. The drive assembly is movable in a non-motorized mode of operation by the manually-driven actuator to permit a transition of the second jaw toward the open position to release tissue between the first jaw and the second jaw.
