摘要:
Circular stapling instruments for cutting and applying one or more surgical staples to tissue are disclosed. The instruments include various forms of feedback systems designed to provide at least one mode of feedback to the surgeon when the anvil has been attached to the device and/or when the anvil has been attached to the device and oriented in a firing position. Various types of feedback indicators are disclosed such as illumination devices, sound generating devices and vibration generation devices. In various embodiments, the feedback indicator comprises at least one illumination device mounted on the anvil which indicates that the anvil has been properly attached to the instrument and which can also serve to illuminate the surgical site.

Circular stapling instruments for cutting and applying one or more surgical staples to tissue are disclosed. The instruments include various forms of anvil locking systems designed to selectively prevent the anvil from moving axially relative to the stapling head of the stapling instrument. One embodiment employs an elongated gear rack that is selectively engagable with locking gears to prevent axial motion of the elongated gear rack and an adjustment shaft used to axially position the anvil. Other embodiments employ a gear assembly that cooperates with the elongated gear rack. A locking member is movably supported by a handle assembly that houses the gear assembly and elongated gear rack. The locking member is configured for selective meshing engagement with the gear assembly to ultimately prevent axial movement of the gear rack and adjustment shaft.

A surgical stapler comprising a first handle portion comprising a staple cartridge channel configured to receive a staple cartridge and a second handle portion comprising an anvil. The stapler further comprises a rotatable latch and a latch projection, wherein the latch is rotatably coupled to one of the first handle portion and the second handle portion and wherein the latch projection extends from the other of the first handle portion and the second handle portion. The latch is configured to engage the latch projection to move the first handle portion and the second handle portion toward one another. In various embodiments, the latch projection comprises a rotatable bearing wherein the latch is configured to contact the rotatable bearing when the latch engages the latch projection.

Tissue thickness compensators for use with circular surgical staplers. Various tissue thickness compensators are disclosed for deployment between a stapler head of a surgical circular stapler and an anvil attached thereto to accommodate variances in tissue thickness during stapling. Some tissue thickness compensator arrangements include means and configurations for deploying healing agents for enhancing the healing process.

A surgical instrument including an elongate member having opposite ends, and a clevis attached to one end of the opposite ends. The clevis has a pair of spaced arms. The instrument includes a pin extending between the spaced arms of the clevis, and a pair of end effectors. Each of the end effectors has a pivot hole adapted for receiving the pin extending between the spaced arms of the clevis for pivotal movement relative to the clevis and a control arm for pivoting the respective end effector about the pin. The control arm includes an actuation hole and a tang adjacent the actuation hole. The instrument includes an actuator wire extending longitudinally to a laterally extending end received within the actuation hole. A portion of the longitudinally extending wire adjacent the laterally extending end and actuation hole is engaged by the tang to maintain the wire in the actuation hole.

A surgical instrument for applying a fastener to tissue. The fastener includes a male component including a base having a hole, a needle receivable in the hole, and a female component including a base and a recess for receiving the needle. The instrument includes a shaft, a first jaw pivotally mounted on the shaft including a receiver for holding the base one component, and a second jaw statically mounted on the shaft including a receiver for releasably holding the base the other component. The first jaw is moveable between an open position and a closed position. The first and/or second jaw includes a channel for slideably receiving a needle. The instrument includes a mechanism for moving the first jaw between the open and closed positions and an ejector for driving the needle through the hole in the male component, through tissue and into the recess of the female component.
