A detachable motor-powered surgical instrument. The instrument may include a housing that includes at least one engagement member for removably attaching the housing to an actuator arrangement. A motor is supported within the housing for supplying actuation motions to various portions of a surgical end effector coupled to the housing. The housing may include a contact arrangement that is configured to permit power to be supplied to the motor only when the housing is operably attached to the actuator arrangement.

A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.

A tool assembly for a surgical stapling instrument includes anvil and cartridge assemblies movable between open and closed positions. The cartridge assembly includes a cartridge body defining a tissue contact surface and rows of staples. The cartridge body defines a first firing channel associated with a first row of staples and a second firing channel associated with a second row of staples. A firing cam is positioned within the first firing channel and translates therethrough during a first axial translation to fire the first row of staples. The first firing cam is biased to move into the second firing channel upon retraction after the first axial translation such that the first firing cam translates through the second firing channel upon a second axial translation to fire the second row of staples.

A motorized surgical instrument is disclosed. The surgical instrument includes a control circuit configured to control the movement of an end effector. If the end effector moves outside a predetermined desired position, the control circuit may activate the energized condition of the motor to move the end effector back to the desired position. When the end effector is in the desired position, the control circuit may engage the de-energized condition of the motor and engage an electromagnetic lock.

A medical securing device for securing an implant device, such as a cardiac implant device with a securing member into a tissue, such an annulus of a heart valve comprises a first elongated stem having proximal and distal ends. The distal end of the first stem has a receiving member for receiving the securing member. During a mutual movement of the distal end of the first stem and the receiving member, the distal end of the first stem is configured to introduce with the receiving member the securing member to the implant device to secure the implant device to the tissue with the securing member.

A surgical stapling system kit is disclosed which comprises a first module comprising, one, a first display system configured to display a first set of data regarding the operation of the first module and, two, a first attachment portion. The kit further comprises, one, a second module comprising a second display system configured to display a second set of data regarding the operation of the second module and, two, a second attachment portion attachable to the first module. The kit further comprises a third module comprising, one, a third display system configured to display a third set of data regarding the operation of the third module and, two, a third attachment portion attachable to the third module to the first module.

A method of surgical stapling that uses a surgical instrument operable to compress, staple, and cut tissue. The instrument includes a body, a shaft, and an end effector with a pair of jaws. A placement tip extends distally from one of the jaws of the end effector. The method includes positioning the end effector at a desired site for surgical stapling. The method also includes controlling one or more of the jaws of the end effector to place the end effector in an open position. The method also includes positioning the end effector such that tissue is located between the jaws. The method also includes clamping the tissue between the jaws by moving at least one of the jaws toward the other jaw. The method also includes advancing a firing beam of the apparatus from a proximal position to a distal position.

A surgical stapling attachment is disclosed. The surgical stapling attachment comprises an attachment portion, a shaft assembly, an articulation joint, and an end effector assembly. The end effector assembly comprises a drive system comprising a closure drive and a firing drive configured to be selectively driven by a single input. The closure drive is configured to clamp tissue between an anvil and a staple cartridge assembly. The firing drive is configured to cut the tissue by deploying a knife and staple the tissue by ejecting a plurality of staples removably stored within the staple cartridge assembly.
