A surgical stapling device that comprises an end effector. According to various embodiments, the end effector comprises a circular anvil having a staple forming surface and a plurality of staples facing the staple forming surface of the anvil. The end effector also comprises a staple driver assembly comprising a plurality of staple drivers. Each staple driver supports one of the plurality of staples and is configured such that, when the staple driver assembly is actuated, each staple driver drives the staple into the staple forming surface of the anvil. A first quantity of the plurality of staple drivers has a first height and a second quantity of the plurality of staple drivers has a second height, wherein the first height is less than the second height.

A surgical stapling device (10) comprising an end effector (12). According to various embodiments, the end effector comprises an anvil (18) having a staple forming surface and a plurality of staples facing the staple forming surface (200) of the anvil. The end effector also comprises a plurality of staple drivers (330) moveable supported within the staple cartridge (302). Each staple driver is in contact with one of the plurality of staples (222) such that when the staple drivers are actuated, the plurality of staples are formed against the staple forming surface of the anvil. A first quantity of the staple drivers have a first height and a second quantity of the staple drivers have a second height, wherein the first height is less than the second height such that the staples driven by the first quantity of staple drivers have a longer formed length than the staples driven by the second quantity of staple drivers.
摘要:
The invention concerns a multi-purpose manually-operated appliance (20) comprising at least two structural parts (3, 4) which can be locked in a closed position to form a compact, substantially closed body in which the two structural parts (3, 4) face each other with preferably congruent contours. In the closed position, the body forms the handle for actuating implements, such a knif, a staple-remover or a cutter, which are embedded in the structural parts and accommodated in a manner such that they can slide out. The two structural parts (3, 4) are preferably interconnected in hinged manner and, when the locking system has been released, can be moved relative to one another in order to actuate a stapler (2), hole-punch (6) or scissors, for example. The structural parts can accommodate further implements, such as a magnifying glass, a pointer or a laser pointer, for example.

Ein Heftgerät (1) zum Eintreiben und Schließen von Heftklammern enthält einen Amboß (4) und einen Gerätekör per (2) mit einem Gehäuse (6), die schwenkbar aneinander gelagert sind. An dem Gehäuse (6)) befindet sich ein Magazin (6) mit Heftklammern, die zu einem am vorderen Ende des Magazins (6) befindlichen Führungskanal (30) gedrückt werden, oberhalb welcher ein Treiberblatt (9) hin- und herverschiebbar gelagert ist. In dem Gehäuse (60) befindet sich ein Elektromotor (18), der über ein Getriebe (17) einen Kurbeltrieb (14, 15) antreibt, mit dem das Treiberblatt (9) in Hin- und Herbewegung versetzt werden kann. Über einen am Gehäuse (60) schwenkbar gelagerten Druckhebel (43) wird einerseits der Amboß (4) gegen das Gehäuse (60) in die Arbeitsstellung geschwenkt und in dieser verriegelt und andererseits der Elektromotor (18) eingeschaltet und in seine Einschaltstellung verriegelt. Erst durch eine vom Elektromo tor (18) angetriebene Nockenscheibe (20) wird nach gedem vollständigen Heftvorgang die Verriegelung des Amboßes (4) sowie der Einschaltstellung des Elektromotors (18) wieder aufgehoben.
摘要:
Stapler (10) having an anvil (70) mounted on a support arm (58) to be movable from a clinching (FIG. 5) to a non-clinching (FIG. 6) position. Stops (66, 68, 72, 94) are provided to retain the anvil (70) in either selected position. To move from one position (FIG. 5) to the other (FIG. 6) a pivot (54) arrangement is provided for the anvil support arm (58) to pivot the same to the frame (30, 32) of the stapler (10). To engage and disengage the stops (66, 68, 72, 94) the anvil support arm (58) is moved axially (FIG. 10) of the pivot (54).
摘要:
A staple cartridge (300) for use with a stapling device (10) that has an actuator (12) that is selectively actuatable in an axial direction and an anvil portion (18) that is selectively movable between open and closed positions is disclosed. Various embodiments of the present invention include a cartridge body (300) that movably supports first and second staple drivers (330,370). The staple drivers (330,370) each support a staple (222) thereon and serve to drive the staples (222) into forming contact with the anvil (18) upon actuation by the actuator (12). The various embodiments of the present invention enable the final formed heights of the staples (222) to be varied without the need to use different sizes of staples (222).

Stapler with metal staples to apply staples with their longitudinal axis inclined by some angular degrees relative to the plane of the stapler, particularly useful to staple, despite its relatively small stapling depth, the sheets of a newspaper in their spine folding as well as, centrally, both open foolscap sheets arranged one on top of the other and sheets folded as an exercise book and to correctly but easily staple sheets arranged one on top of the other in their top left corner.
摘要:
A surgical fastener applying apparatus (1000) includes an anvil section (1014) and a cartridge section (100), where the cartridge section and the anvil section are movable from an unclamped position to a clamped position to clamp tissue therebetween. The cartridge section has a plurality of retention slots (126). A plurality of first surgical fasteners (130) and a plurality of second surgical fasteners (130a) are disposed within a corresponding retention slot. The plurality of first surgical fasteners has a first backspan with a first configuration and the plurality of second surgical fasteners has a second backspan with a second configuration. The first configuration is different from the second configuration. In addition, when the first configuration applies a first compressive force to tissue upon formation of the plurality of first surgical fasteners and the second configuration applies a second compressive force to tissue upon formation of the plurality of second surgical fasteners, the second compressive force is different from the first compressive force.
