A surgical stapler includes a first elongate member having a distal portion that supports an anvil surface, and a second elongate member having a distal portion configured to receive a staple cartridge. The stapler further includes a pin rotatably coupled with the first elongate member, and a clamp member movably coupled with the second elongate member. The clamp member is operable to releasably capture the pin to thereby clamp the first elongate member against the second elongate member. The pin is configured to rotate relative to the first elongate member in response to being captured by the clamp member.

Clamping assembly for linear surgical stapler

In various embodiments, a surgical stapling instrument can include a handle, a shaft extending from the handle, wherein the shaft defines an axis, and a disposable loading unit which is assembled to the shaft in a direction which is transverse to the shaft axis. Such a connection between the disposable loading unit and the shaft can prevent, or at least inhibit, the disposable loading unit from being unintentionally displaced proximally and/or distally relative to the shaft of the surgical instrument. The surgical stapling instrument and/or disposable loading unit can further include a threaded collar and/or detent assembly configured to hold the disposable loading unit in place. In various embodiments, a disposable loading unit can include a lockout feature which can prevent, or at least inhibit, an expended disposable loading unit from being reassembled to the elongated body of the surgical instrument.

End effector coupling arrangements for a surgical cutting and stapling instrument

A modular shaft assembly is disclosed. The modular shaft assembly includes one or more inputs configured to receive input motions from a surgical instrument system, such as a handle, for example. The shaft assembly further includes one or more on-board inputs configured to generate input motions. The input motions received and generated by the shaft assembly are transferrable to an end effector of the shaft assembly to perform various functions at the end effector. The end effector can include a staple cartridge and a firing member which is movable between a proximal position and a distal position to eject staples from the staple cartridge. The end effector can include a plurality of jaw members and the firing member can comprise camming members which are configured to position the jaw members relative to one another.

Modular stapling assembly

Anvil for surgical stapler

Surgical stapler

A surgical stapling assembly comprising an end effector, a shaft assembly extending proximally from the end effector, a housing, a rotary motion actuator supported by the housing, a first actuation system configured to cause the end effector to perform a first function, a second actuation system configured to cause the end effector to perform a second function different from the first function, and a selector arrangement transitionable between a first orientation and a second orientation is disclosed. The end effector comprises a staple cartridge and staples deployable from the staple cartridge into tissue. The rotary motion actuator is configured to operably interface with the first actuation system in the first orientation to cause the end effector to perform the first function. The rotary motion actuator is configured to operably interface with the second actuation system to cause the end effector to perform the second function.

Surgical stapling assembly comprising first and second actuation systems configured to perform different functions

A surgical stapling assembly comprising a firing member, an end effector, a closure member, and a shaft including an attachment interface is disclosed. The surgical stapling assembly is configured to be attached to a surgical instrument interface by way of the attachment interface. The end effector comprises a first jaw, a second jaw, and a staple cartridge comprising staples configured to be ejected by the firing member. The second jaw is movable relative to the first jaw between an open position, a fully-clamped position, and a collapsed position. The end effector further comprises an interconnection between the first jaw and the second jaw defining a rotational axis about which the second iaw is movable relative to the first iaw. The rotational axis is shiftable toward and away from the first iaw as the second iaw is moved between the open position, the fully-clamped position, and the collapsed position.

An apparatus includes a body, an anvil, a firing assembly, and a closure assembly. The firing assembly includes a staple driver, a deck member, and an annular array of staples. The closure assembly includes a trocar, a knob, and a limiting adjustment feature. The trocar is configured to actuate the anvil relative to the body to capture tissue between the anvil and the deck member. The knob is configured to rotate relative to the body to actuate the trocar relative to the body. The limiting adjustment feature is configured to selectively rotate the knob to actuate the trocar and the anvil proximally until tissue captured between the anvil and the deck member is compressed under a predetermined maximum clamping force. The limiting adjustment feature is configured to slip relative to the knob when tissue captured between then anvil and the deck member is compressed over the predetermined maximum clamping force.

Circular stapling instrument with torque limiting feature

A surgical tool for use with a surgical instrument including a handle assembly and an elongated body defining a longitudinal axis and a drive system is disclosed. The surgical tool comprises a carrier removably couplable to the elongated body, an anvil movably supported for selective movement relative to the carrier in response to drive motions from the drive system, a tissue thickness measuring member movably supported in the carrier and configured to move toward and away from an underside of the anvil in a direction that is transverse to the longitudinal axis, and a sensor arrangement supported between the tissue thickness measuring member and the carrier. The sensor arrangement is configured to interface with an indicator member to provide an indication of a thickness of tissue clamped between the anvil and the tissue thickness measuring member at a location that is proximal to the anvil when in use.
