摘要:
A surgical instrument includes an end effector extending along a jaw centerline. A staple cartridge is received in the end effector. The staple cartridge includes deck, staples, a wedge sled, and a driver assembly. The staples are positioned in respective openings formed through the deck. The wedge sled is slidable through the staple cartridge. The driver assembly has a first driver and a second driver. The first driver receives a first staple of the plurality of staples. The second driver receives a second staple of the plurality of staples. The driver assembly is configured to be engaged by the wedge sled sliding toward the distal sled position and thereby be forced toward a first jaw of the end effector, thereby forcing the first and second staples toward an anvil of the first jaw for formation in tissue. The driver assembly is positioned along the centerline.
摘要:
A surgical stapling instrument comprising an elongate shaft assembly that that defines a shaft axis and includes a surgical end effector that is operably coupled thereto by an articulation joint. The surgical instrument further includes a rotary articulation member that is supported for rotation travel about a rotary axis that is transverse to the shaft axis. A first distal articulation driver assembly and a second distal articulation driver assembly operably interface with the surgical end effector and the rotary articulation member such that rotation of the rotary articulation member causes the first and second distal articulation drivers to articulate the surgical end effector relative to the shaft axis.

A surgical stapler. The surgical stapler includes a drive system, a handle assembly, an electric motor, a battery and a control system. The drive system includes a movable drive member. The handle assembly includes a frame configured to support the movable drive member. The electric motor is mechanically coupled to the drive system. The battery is electrically couplable to the electric motor. The control system is electrically connected to the electric motor and includes a sensor positioned on the frame. The control system is configured to control the electric motor based on a force applied to the frame by the movable drive member.
摘要:
A surgical stapling instrument including staples and an implantable layer is disclosed. The implantable layer comprises fibers which have undergone a kinking process. The kinked fibers, once interwoven together, create a resilient body that can dynamically adapt to the thickness of the tissue captured within the staples.

A surgical instrument includes a shaft assembly, a handle assembly, and a latch system configured to operatively couple the shaft and handle assemblies. The latch system includes shaft and a handle lock members respectively connected to the shaft and handle assemblies for inhibiting operative uncoupling of the shaft and handle assemblies. The latch member has a cam surface and a latch member. The latch member is configured to selectively move from a locked position to a released position such that movement of the latch member causes the shaft and handle lock members to disengage and uncouple the shaft and handle assemblies. The latch member is further configured to selectively move from the released position to a removal position such that further movement of the latch member causes the cam surface of the latch member to engage the cam base and urge the shaft assembly in a removal direction.

Surgical end effectors and fastener cartridges having firing lockout arrangements for preventing or limit a firing stroke when a cartridge has not been operably installed in the end effector or a spent cartridge has not been replaced.
摘要:
An apparatus includes a locking portion, a flexible pulling portion, a flexible body, and a plurality of barb features extending laterally from the body. The locking portion is configured to receive the pulling potion. The pulling portion is configured to engage and translate relative to the locking portion after the locking portion has received the pulling portion. The flexible body extends from the locking portion to the pulling portion. The flexible body is configured to form a loop when the pulling portion engages the locking portion. The loop is configured to decrease in size in response to pulling of the pulling portion relative to the locking portion. The barb features are configured to engage a tubular region of tissue and thereby form pleats in the tubular region of tissue.
