A stapler including a moveable strike plate and accessibility features is described. A slidable strike plate is moveable from a first staple forming position to a second staple forming position to form different staple shapes. The slidable strike plate is moved relative to the anvil of the stapler with a single hand to change positions. A rotatable strike plate is turned with a single hand to move between staple forming positions by rotating an outer dial of the rotatable strike plate relative to the anvil of the stapler. The stapler includes an indicator window that shows if the stapler is empty or running low on staples and a quick release staple loading magazine that is operable using a single hand.

A binding machine includes: a main handle configured to accommodate a staple; a staple driver supported by the main handle and configured to drive the staple; and a clincher arm rotatably attached to the main handle and including a clincher, the clincher being configured to clinch the staple driven by the staple driver. The staple driver includes: a driving portion that extends in a direction away from the main handle and is configured to drive the staple toward the clincher, and an attachment portion with which the driving portion is attached to the main handle, and the attachment portion extends in a longitudinal direction of the main handle from a side edge of the driving portion.

A surgical staple cartridge assembly that comprises an anvil, a staple cartridge jaw, a longitudinal knife channel, a first longitudinal row of staple pockets comprising a first distal end staple pocket, a second longitudinal row of staple pockets comprising a second distal end staple pocket, a third longitudinal row of staple pockets, staples removably positioned within the staple pockets, a staple driver, and a firing member is disclosed. The staple driver is configured to drive a first distal staple out of the first distal end staple pocket and a second distal staple out of the second distal end staple pocket and, in cooperation with the anvil, deform the first distal staple to a first fired height and the second distal staple to a second fired height. The firing member comprising a first portion configured to engage the anvil and a second portion configured to engage the staple cartridge jaw.

An end effector comprising a first jaw, a plurality of staple cavities, a first slot, a first longitudinal row of first staples, a second longitudinal row of second staples, a second jaw, an anvil comprising forming pockets, a staple driver, and a firing member is disclosed. The staple driver supports a first staple removably stored in said first longitudinal row and a second staple removably stored in said second longitudinal row. The staple driver and said anvil are configured to co-operate to deform said first staple to a first fired height and to deform said second staple to a second fired height. The firing member comprises a first portion configured to extend through said first slot and a second portion configured to engage said anvil. The anvil further comprises a second slot including a lateral portion extending behind a longitudinal row of said forming pockets.

A clinch fastener mechanism including a pivoting base configured to be pivotally connected to a pneumatic fastener tool. The clinch fastener mechanism further includes a clinch arm pivotally connected to the pivoting base at a proximal end of the clinch arm; and a clinch plate disposed on a distal end of the clinch arm, wherein tool operates within three pressure zones. The system may also include a two-valve system which works by moving pressure throughout three specific zones. The first pressure zone has pressure introduced to it by the user attaching the tool to a pressure delivery source, such as a compressor, or other source. The second pressure zone may be used to operate the clinch arm or a safety mechanism. Mechanical safeties may be configured to prevent accidental or double firing of the tool.

A staple cartridge for use with a stapling device that has an actuator that is selectively actuatable in an axial direction and an anvil portion that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body that movably supports first and second staple drivers. The staple drivers each support a staple thereon and serve to drive the staples into forming contact with the anvil upon actuation by the actuator. The various embodiments of the present invention enable the final formed heights of the staples to be varied without the need to use different sizes of staples.

A fastener driving tool includes a magazine unit, a handle, a striking plate, an energy restoring member and a wire bending spring disposed to a housing unit. The housing unit includes an inner housing assembly made from a plastic material, and an outer housing assembly made from a metal material and covering the inner housing assembly. The wire bending spring is biased for storing a striking energy for the striking plate, and includes an extending section and a backwinding section. The extending section has first and second ends. The backwinding section is connected with the second end, and extends and bends toward the first end to terminate at a terminal end portion. The ratio of a height to a width ranges from 1:1 to 1:1.6.

A magnetically detachable stapler device is provided that utilizes a bottom housing having a first magnetic coupling element. The first magnetic coupling element utilizes a first low friction material layer disposed thereupon. The stapler device utilizes a top housing having a coupling base structure, a magazine and a hammer. At least one of the top housing, the magazine and the hammer moves relative the coupling base structure. The coupling base structure utilizes a second magnetic coupling element which itself has a second low friction material layer disposed thereupon.
