A surgical instrument that includes a handle assembly that removably supports a source of pneumatic power. A pneumatically powered drive system is operably supported by the surgical instrument and is configured to be fluidically coupled to the source of pneumatic power. The handle assembly may be provided with a lockout system that is configured to block connection of the source of pneumatic power to the portion of the handle assembly and the pneumatically powered drive system after the source of pneumatic power is disconnected from the portion of the handle assembly and the pneumatically powered drive system a predetermined number of times. In alternative embodiments the handle assembly may be provided with attachment components that either break off or are otherwise disabled to prevent the reattachment of the source of pneumatic power to the handle assembly after the source has been detached therefrom.

Various forms of surgical instruments are disclosed. In various embodiments, the instrument includes a cartridge supporting assembly for operably supporting a staple cartridge therein. The cartridge supporting assembly may be responsive to firing and retraction motions applied thereto from a firing assembly. An anvil may be operably coupled to an anvil closure assembly. The anvil closure assembly may be constructed to selectively move the anvil in a proximal direction toward the cartridge supporting assembly to enable a portion of tissue to be clamped between a cartridge supported by the cartridge supporting assembly and the anvil under a predetermined amount of compression. The device may further include a closure actuator that operably interacts with the anvil closure assembly such that as the closure actuator is moved in a first direction, the anvil closure assembly causes the anvil to move in the proximal direction to increase the compression of the tissue between the staple cartridge and the anvil. A variable load generating member may cooperate with the anvil closure assembly and the closure actuator to apply a resistive load to the closure actuator in relation to an amount of compression applied to the tissue between the anvil and the staple cartridge.

A surgical stapling and severing instrument particularly suited to endoscopic procedures incorporates a handle that produces separate closing and firing motions to actuate an end effector. In particular, the handle produces multiple firing strokes in order to reduce the required amount of force required to fire (i. e. , staple and sever) the end effector. A linked transmission reduces the required handle longitudinal length, yet achieves a rigid, strong configuration when straightened for firing. A spring-biased side pawl firing mechanism is enabled by activation of an Electroactive Polymer (EAP) block actuator that overcomes a disengagement spring bias and moves a linked rack into proximity with a side pawl firing mechanism. Thereby, various sensed or commanded inputs may be incorporated to prevent inadvertent firing.

A surgical severing and stapling instrument clamps tissue in a staple applying assembly comprising a lower jaw of an elongate channel holding a staple cartridge and a pivotally opposed upper jaw (anvil). A firing handle drives a rack in a handle connected to a firing rod and bar that pass through an elongate shaft and into the staple applying assembly to sever and staple tissue. Upon release of the firing handle, a retraction spring assists in withdrawing the rack and other firing components. To advantageously assist in firing, a spring biased plunger is cocked prior to firing to impart assistance upon depression of the firing trigger. Alternatively, a torsion coil spring ratchet mechanism is preload to act through a gear into the rack to assist. As a further alternative, a retraction spring is preload and disengaged until the rack is fully fired.

A surgical instrument for use in connection with a pneumatically powered tool having a firing mechanism operably supported therein that is movable between an unactuated position and an actuated position. In various embodiments, a drive system is supported by at least one of a handle assembly and an elongate shaft assembly and is configured to selectively apply a firing motion to the firing mechanism of the pneumatically powered tool to cause the firing mechanism to move from the unactuated position to the actuated position in response to a flow of gas from a source of gas fluidically coupled to the drive system. A travel monitoring member is operably supported by the handle assembly and is linked to the drive system to provide an indication of progress of the firing mechanism of the pneumatically powered tool as the firing mechanism moves from the unactuated position to the actuated position.

A self contained motor-powered disposable loading unit for use with a surgical cutting and stapling apparatus. The disposable loading unit may contain a battery that is retained in a disconnected position when the disposable loading unit is not in use and is moved to a connected position when the disposable loading unit is coupled to the surgical cutting and stapling apparatus to permit the motor to be selectively powered thereby. Indicators may be supported on the disposable loading unit to indicate when the axial drive assembly thereof is in a starting position and an ending position. Another indicator may be provided to indicate when the anvil assembly is in a closed position.

A surgical instrument that includes a distal member configured to receive a pneumatically operated tool assembly therein. The instrument may also include an elongate shaft assembly that has a distal end portion that is coupled to the distal member and a proximal end portion. A drive member may be supported by the distal end portion of the elongate shaft assembly and may be configured to apply at least two actuation motions to the pneumatically operated tool assembly upon receipt of at least one pneumatic drive signal from a source of pneumatic power. The drive member may comprise a dual-acting cylinder, a single-acting cylinder, a bellows assembly, etc. The distal end portion of the elongate shaft member may articulate relative to the proximal end portion thereof and/or the distal end portion of the elongate shaft assembly may be detachable from the proximal end portion.
