A surgical instrument comprises an elongate flexible forceps member having a diameter sufficiently small so that the forceps member is slidably insertable into a biopsy channel extending longitudinally through a flexible tubular endscope member, the forceps member being provided at a distal end with a pair of forceps jaws each formed on an inwardly facing surface with a longitudinally extending groove. A staple having a spring bias construction tending to force the staple into an opened configur...

An instrument for stapling body tissue including a staple, a retainer, and a plunger. The staple is preformed in a closed state and is made of a body-compatible material. The staple material has a stress plateau such that the staple may be flexed to an open state without permanent deformation. The retainer stores the staple in the open state and the plunger ejects the staple from the retainer such that the staple returns itself to the preformed closed state in the body tissue.

A stapling device includes a wire fed in the casing of the device and a staple-bending member is movably connected to a base in the casing and has two protrusions extending from a lower end thereof. An ejecting member movably connected to the base. A mechanism is driven by an activation member and lowers the staple-bending member and the ejecting member to deform a section of the metal wire to be a staple which is ejected through an aperture to staple a pile of document.

A stapling apparatus for a booklet maker is described which provides a compact and low cost booklet maker for desktop publishing.
