A handle assembly for use with a surgical tack applier includes an actuation assembly and an articulation lever assembly configured to articulate an articulation portion of the surgical tack applier. The actuation assembly includes a motor, an actuation rod, and an actuation switch configured to actuate the motor. The actuation rod has a first end operatively coupled to an output shaft of the motor for concomitant rotation therewith, and a second end operatively coupled to a loading unit of the surgical tack applier such that rotation of the actuation rod ejects a surgical tack from the loading unit. The articulation lever assembly includes an articulation rod operatively coupled with an articulation portion of the surgical tack applier such that axial displacement of the articulation rod causes articulation of the articulation portion, and an articulation lever operatively coupled with the articulation rod.

Powered surgical tack applier

A powered surgical tack applier is configured to deploy a surgical tack through tissue or a surgical mesh. The surgical tack applier is articulatable to facilitate placement of the surgical tack to a desired surgical location. The powered surgical tack applier includes a power module that includes a battery, a motor, and a gear box. The power module provides a high-speed/low-toque output and a low-speed/high-torque output.

A surgical instrument module for powering a plurality of discrete surgical end effectors includes a motor, a planetary gear box, a high-torque/low-speed output operably coupled to the motor, and a high-speed/low-torque output operably coupled to the motor. The high-torque/low-speed output is configured to be operably coupled to a driven member of a first type of surgical end effector, and the high-speed/low-torque output is configured to drive an operation of a second type of surgical end effector.

Hand-held surgical instruments

A hand-held surgical instrument includes a handle housing, a shaft portion extending distally from the handle housing, and an articulation shaft. The articulation shaft may be configured to axially move within the shaft portion to articulate an end effector via a manual activation or a motor activation.

A surgical device includes an end effector and a handle assembly operably coupled to the end effector. The end effector includes an anvil assembly and a cartridge assembly pivotally coupled to one another. The cartridge assembly includes a staple cartridge, a cartridge carrier, and a strain gauge. The cartridge carrier includes an elongated support channel configured to receive the staple cartridge, the elongated support channel defined by an inner first surface and a pair of inner second surfaces. The inner first surface includes a recess defined therein, and the strain gauge is disposed within the recess. The handle assembly includes a power-pack configured to receive sensor data from the strain gauge of the end effector and to control a function of the end effector in response to the sensor data.

Powered surgical devices including strain gauges incorporated into flex circuits

A surgical stapling apparatus is provided and includes a housing having an actuator; an elongated member extending from the housing; an end effector disposed on an end of the elongated member, the end effector having a first jaw and a second jaw, the first jaw having a staple cartridge and the second jaw having a plurality of staple forming recesses; the staple cartridge having at least a first segment and a second segment, the first segment and the second segment each having a tissue contacting surface and staple receiving slots defined in the tissue contacting surface, the first segment and the second segment being biased toward the second jaw and movable; a biasing members for each of the first segment and the second segment; and a pressure sensor for each of the first segment and the second segment.

Surgical stapling apparatus

A surgical grasper includes an articulation assembly configured to enable a tool assembly to pivot in a first plane and articulate in a second plane orthogonal to the first plane. The surgical grasper eliminates the center line pivot joint used in conventional articulation mechanism, which, in turn, enables use of thicker cable that provides greater clamping force of first and second jaws of the tool assembly.

Surgical device including two-cable hemispherical grasper

The present disclosure relates to a surgical device including an adapter assembly for selectively interconnecting an end effector and the device housing. The adapter assembly includes at least one drive converter assembly that converts and transmits a rotation of the rotatable drive shaft to an axial translation of at least one axially translatable drive member of the end effector. A first drive converter assembly includes a first drive element, a nut, an articulation sleeve, an articulation bearing, and an articulation link. Rotation of the rotatable drive shaft results in rotation of the first drive element. Rotation of the first drive element results in axial translation of the nut, the articulation sleeve, the articulation bearing, the articulation link, and the at least one axially translatable drive member of the end effector.

Handheld surgical handle assembly, surgical adapters for use between surgical handle assembly and surgical end effectors, and methods of use

A surgical apparatus is provided. The surgical apparatus includes a proximal body portion, a distal body portion selectively articulable relative to the proximal body portion at an articulation joint, and a first drive gear disposed within the distal body portion. The distal body portion has a diameter and a length. The length of the distal body portion is substantially the same as the diameter of the distal body portion.

Adapter assembly and loading units for surgical stapling devices

A surgical stapling device includes a staple reload and a shipping wedge. In embodiments, the shipping wedge is configured to disable the use of a staple reload if the staple reload does not have an actuation sled. In other embodiments, the actuation sled includes a readable identifier that facilitates confirmation of the presence of an actuation sled within a staple reload from a location externally of the staple reload.

Sled detection device

A surgical stapling system includes a surgical stapling apparatus and a staple cartridge surgical buttress assembly. The surgical stapling apparatus includes a handle assembly, an elongate tubular body extending distally from the handle assembly, and an end effector extending distally from the elongate tubular body. The end effector includes an anvil assembly and a staple cartridge assembly. The staple cartridge surgical buttress assembly includes a surgical buttress and a leash. The surgical buttress includes a body having an annular configuration and legs extending from the body. The body is positioned against a tissue facing surface of the staple cartridge assembly and the legs are positioned against a housing of the staple cartridge assembly. The leash is threaded through at least one of the legs and extends proximally from the surgical buttress towards the handle assembly.

Surgical buttress loading and attaching/detaching assemblies

An adapter assembly includes an articulation nut, an articulation link, and a drive belt operably coupled to a distal portion of the articulation link. The articulation link has a proximal end portion operably coupled to the articulation nut, such that rotation of the articulation nut results in translation of the articulation link. The drive belt has a distal end portion configured to be operably coupled to a proximal end portion of a surgical loading unit, such that movement of the drive belt articulates the surgical loading unit relative to the adapter assembly.

Surgical instrument including an adapter assembly and an articulating surgical loading unit

An adapter assembly includes a switch actuator, an actuation bar, and a latch. The switch actuator is movable between a proximal position, in which the switch actuator actuates a switch, and a distal position. The latch is movable between a first position, in which the latch permits proximal movement of the switch actuator, and a second position, in which the latch prevents proximal movement of the switch actuator. The latch is configured to move from the first position toward the second position in response to the actuation bar moving toward a proximal position.
