A surgical fastener application device includes an anvil half, a cartridge receiving half, a firing assembly including a push plate, and a locking assembly. The cartridge receiving half defines an elongated channel member. The elongated channel member is configured to receive a single-use loading unit (SULU). The locking assembly is supported in the elongated channel member and includes a locking element that selectively engages with the push plate to prevent movement of the push plate relative to the locking element when the SULU is not supported in the elongated channel member.

A surgical stapler, the end effector includes a fastener-cartridge assembly and an anvil; the closing mechanism drives the end effector to be closed; the surgical fastener pushing assembly pushes the surgical fastener out of the fastener-cartridge assembly; in a closing stage, the first driver mechanism is in detachable connection with the closing mechanism to drive the closing mechanism to close the end effector; in a surgical fastener pushing stage after the closing stage, the first driver mechanism is separated from the closing mechanism and drives the surgical fastener pushing assembly to push the surgical fastener out of the fastener-cartridge assembly to suture the target tissue; the articulation mechanism and the rear articulation driver assembly drive the end effector to pivot; the detachable portion is in detachable connection with the main body portion to enable the front articulation driver assembly to be in detachable connection with the rear articulation driver assembly.

Surgical instruments and / or fastener apparatuses comprising an end effector with a pair of jaws pivoted at a proximal end thereof and movable between an open and closed position. At least one of the jaws may comprise a channel for receiving a cartridge containing a plurality of surgical fasteners. Also, an electrically powered actuator may be for deploying the surgical fasteners and may comprise a power source and a motor. An activation mechanism may be attached to the handle to move the pair of jaws from the open to the closed position and to activate the actuator. A lockout mechanism may be configured to permit current to flow from the power source to the motor when the pair of jaws is in the closed position and to prevent current from flowing to the power source to the motor when the pair of jaws is in the open position.

A surgical fastener applier having a housing containing a compartment therein, an elongated member extending distally from the housing and first and second jaws. A firing mechanism is positioned within the housing movable to a second position to effect firing of fasteners. A power pack is removably loadable into the compartment, the power pack having one or both of a) a first motor and a first engagement member removably engageable with the firing mechanism when the power pack is loaded into the compartment to effect movement of the firing mechanism; and b) a second motor and a second engagement member removably engageable with an articulating mechanism in the housing of the surgical fastener applier to effect movement of an articulation mechanism to effect articulation. One or both of a firing position and an articulation position are tracked during the surgical procedure. Sensors are provided to detect select parameters and instrument functions.

A surgical fastener includes a cannulated collapsible fastening body having a trailing end and a leading end and defining a passage extending from the trailing end to the leading end, and a pin having a non-threaded shaft at least partially disposed within the passage and an enlarged tip. A method of using the surgical fastener includes engaging an end of a driver with a recess in a head of the surgical fastener, including inserting an extension at the end of the driver into the passage, and inserting the fastener into a bore in a bone during which the extension of the driver abuts a trailing end of the shaft of the pin to prevent the pin from moving in a direction from the leading end to the trailing end relative to the fastening body.
