A surgical stapler, preferably in a single use disposable form, comprises a combination of a staple feeding mechanism and a staple forming mechanism secured in a frame and an actuating trigger functionally connected to both the staple feeding mechanism and the staple forming mechanism, wherein the staple feeding mechanism includes a rail to guide contained staples serially to a staple forming position and a shuttle in association with the rail as a movable staple retaining cover, the shuttle being functionally connected to the trigger for movement in the same direction and the same time as the staples. This structure provides a reliable surgical stapler in which staples are not likely to jam the staple feeding mechanism.

A method and a mechanism in and for a fastener dispensing operation, by which a plurality of fasteners individually comprising a filament having a head and an anchor bar at one and the other ends thereof and altogether integrally formed to a fastener assembly can be fed to a fastener-severing position in a fastener dispensing device one at a time of the fastener dispensing operation by the dispensing device even in case of an irregularity or a change in the inter-fastener pitch in the fastener assembly.

A stapler includes a press handle, a loading arm for filling a staple stick having a side window thereon, an anvil base and a magazine prefilled with several sticks of staples engaged with the side window of the arm and having an angled spring plate normally braking a staple stick, whereby upon the retraction of a pusher in the arm, the angled spring plate in the magazine will be straightened to release a standby staple stick tensioned by a leaf spring in the magazine to be filled into the loading arm for convenient refilling of staples without uncovering the loading arm.

Device and method for inserting an information carrier in a substrate. The information carriers are stored in a storage and with the aid of transfer means are removed one by one from said storage with the aid of vacuum. The transfer means then place the information carrier concerned in the insertion element, which then executes the insertion stroke.

The present invention provides a device for advancing fasteners in a magazine to a fastening tool. A plate assembly includes a base plate rigidly connected to a feed track and a pivot plate pivotally connected in a parallel orientation to the base plate. A motor is mounted to the pivot plate in such a manner that the motor shaft projects through apertures near the center of each plate. A clutch assembly is mounted to the motor shaft and engages fasteners on the feed track. As the motor shaft rotates, the clutch assembly provides a friction force for advancing fasteners along the rack as each fastener is ejected. Between fastener ejections, the clutch assembly rotates and slips about the motor shaft.
