An electric carpet stapler comprises a trigger and switch assembly that has an actuation caused by a change of state of a sensor, which causes the sensor to send a signal to a control circuit to begin a process to supply power to a winding. The trigger and switch assembly includes a trigger that moves in a trigger actuation direction to move a sensor actuator in a sensor actuation direction, causing a change of state in the sensor, which causes the control circuit to begin the process to supply power to the winding. The trigger and switch assembly may also include a toggle. At the actuation of the trigger and switch assembly, the toggle creates a mechanical instability, and a toggle signal to the user, which may be produced mechanically.

A tool includes a mechanical energy storage such as a helical spring, and an ejecting device to be linearly moved between a clamping position and an ejecting position. The ejecting device has a driver element and a shooting device, and an electric motor and a spindle drive driven by the electric motor converts a rotational movement of the electric motor into a linear movement of the ejecting device. A control device controls the rotation of the electric motor, and the ejecting device can move toward the clamping position by rotation of the spindle drive in a first direction of rotation. A locking device can lock the shooting device in the clamping position, and the shooting device can be released and moved toward the ejecting position by actuating the locking device. The driver element can be moved toward the ejecting position by rotating the spindle drive in a second direction.

Disclosed is a surgical stapling apparatus and method of use that includes a cartridge assembly which is capable of being reloaded during a surgical procedure without being removed from the surgical site. This allows a surgeon to continue a surgical operation without withdrawing or removing the surgical stapler for reloading and thus reduces the length of the surgery while allowing the physician to concentrate solely on the surgical procedure rather than dividing attention between the surgical procedure and reloading of the surgical stapler. The surgical stapling apparatus includes an elongate member having a plurality of fasteners arranged in a plurality of longitudinally extending rows which is longitudinally translatable through the cartridge to position the plurality of fasteners relative to a plurality of retention slots extending through an upper surface of the cartridge.

A wire stapler for tacking an elongate element at an elevated location is disclosed herein. The element may be one of a cable, a rope light, decorations, and the like. The wire stapler comprises a handle. An elongate hammer is coupled to the handle and extends therefrom. An elongate sleeve is configured to receive the elongate hammer therewithin. A sleeve end is configured for coupling at an operative end of the sleeve, wherein the sleeve end includes a staple receiving pocket configured thereon for receiving a staple therein, wherein the hammer is configured for reciprocation within the sleeve and collision with the staple for tacking the element accommodated between the staple at the elevated location.

A staple apparatus can comprise a staple head movable in a first staple direction from a head retracted position to a head extended position. The staple apparatus can further comprise an indexing apparatus comprising an index biasing member and an indexing member. The indexing member can be positioned at least partially within an indexing area and biased with the index biasing member toward a member extended position relative to the indexing area. The indexing member can define a rung travel path and can further comprise an indexing tab comprising a ramp surface positioned to taper the rung travel path in the first indexing direction. The indexing tab can further comprise a shoulder positioned past at least a portion of the ramp surface in the first indexing direction. In further embodiments, a staple chain positioning apparatus can comprise a push member movable in an extension direction.

A surgical stapler, or fastening instrument, may generally comprise a layer, such as a tissue thickness compensator, for example, releasably attached to a fastener cartridge and/or anvil by a flowable attachment portion. The flowable attachment portion may be indefinitely flowable. The flowable attachment portion may be flowable from the time that layer is installed to the fastener cartridge to the time in which the layer is implanted to patient tissue. The flowable attachment portion may comprise a pressure sensitive adhesive. The flowable attachment portion may comprise an adhesive laminate comprising a base layer comprising the tissue thickness compensator and an adhesive layer on at least a portion of a surface of the base layer comprising the pressure sensitive adhesive. Articles of manufacture comprising flowable attachment portion and methods of making and using the flowable attachment portion are also described.

A stapler is provided, including: a main body, including a front end portion, the front end portion including a staple outlet and a plate member, the plate member including a concave adjacent to the staple outlet; a holder, switchably disposed on the main body, including a plurality of notches with different sizes and a plurality of first positioning portions; and a positioning member, disposed on the main body, releasably positioned with one of the plurality of first positioning portions so that one of the plurality of notches corresponds to the concave in a front to rear direction, for receiving a portion of a cable.

An electric carpet stapler comprises a trigger and switch assembly that has an actuation caused by a change of state of a sensor, which causes the sensor to send a signal to a control circuit to begin a process to supply power to a winding. The trigger and switch assembly includes a trigger that moves in a trigger actuation direction to move a sensor actuator in a sensor actuation direction, causing a change of state in the sensor, which causes the control circuit to begin the process to supply power to the winding. The trigger and switch assembly may also include a toggle. At the actuation of the trigger and switch assembly, the toggle creates a mechanical instability, and a toggle signal to the user, which may be produced mechanically.

A target illuminating stapling device for safely fastening an item to a substrate includes a staple gun and a bulb. The staple gun comprises a staple driver, a handle, and a staple cartridge. The staple driver is positioned in a front portion of the staple gun. The handle is hingedly engaged to the front portion and extends over a back portion of the staple gun. The handle is operationally engaged to the staple driver. Levering of the handle actuates the staple driver to fasten a staple into a substrate. An item that is positioned between the staple and the substrate is fastened to the substrate. The staple cartridge selectively feeds the staple to the staple driver. The bulb is engaged to the staple gun proximate to the staple driver. The bulb selectively illuminates a target area of the substrate into which the staple is to be fastened.

A fastener cartridge can comprise a support portion, a tissue thickness compensator positioned relative to the support portion, and a plurality of fasteners positioned within the support portion and/or the tissue thickness compensator which can be utilized to fasten tissue. In use, the fastener cartridge can be positioned in a first jaw of a surgical fastening device, wherein a second jaw, or anvil, can be positioned opposite the first jaw. To deploy the fasteners, a staple-deploying member is advanced through the fastener cartridge to move the fasteners toward the anvil. As the fasteners are deployed, the fasteners can capture at least a portion of the tissue thickness compensator therein along with at least a portion of the tissue being fastened.
