Abstract: A surgical stapler having a pivotable trigger in a housing and a cartridge of surgical staples, has a moving anvil which receives one staple at a time in its open configuration. A forming blade moves to engage and capture the staple between the forming blade and the anvil and drive the staple away from the cartridge allowing the user to see and place the points of the staple at a desired location on the tissue. Further movement of the forming blade pressing upon the top of the staple forces the staple legs to pierce and close joining adjacent edges of tissue. First and second stripper elements acting separately or in combination engage and urge the closed staple to separate from the anvil.

An indexer then rotates the cylindrical support to align another rail with the follower to feed the staples on the other rail into the stapler. A pneumatic control coordinates the stapler and the reloading apparatus.

Abstract: The method of assembling lead-mounted electric components such as DIP 18 in automated fashion to a printed circuit board 14 is accomplished by building up a crimping tool (FIG. 7) comprising a base 28 with crimping anvils 12, 20, 22, 24, by selectively positioning and orienting the anvils on the base while the base is energized to provide a moderately low strength field, and the base is then energized to provide an adequately high strength magnetic field to retain the anvils properly during the subsequent steps of mounting the components to the board and crimping the leads to produce a particular type of board. After the requisite number of boards of a particular type are built, the anvils are removed to storage and the base is rebuilt to provide a different array of anvils for a different board.

The clincher ears 204 are pivotally mounted on the housing 202 and rotatable by the actuator 223 so as to engage and bend the staple legs. The or each clincher ear 204 is mounted, suitably by having a slotted pivot hole 212, so that it also moves normally to the support surface during and/or following the end part of the rotational movement of the ear.

Abstract: The invention relates to an apparatus for pressing-in belt connectors, the ressing-in lever of which is driven by two elbow lever systems. In such a pressing-in apparatus a control lever (5) is positioned between the two elbow lever systems. The control lever is driven by the driving elbow lever pair during the first phase of the pressing-in operation. The control lever locks the driven elbow lever pair in the attained end position during the second phase of the pressing-in operation. Therefore, this invention provides a pressing-in apparatus, which works without a curve or cam control for the non-symmetrical closing movement, yet still permits very high pressure attachment forces while being light in weight.

Abstract: A surgical stapling assembly including a resiliently mounted anvil member and a staple holding assembly containing a plurality of surgical staples and mounted relative to the anvil member for movement into substantially parallel spaced relation thereto to clamp tissue inserted between the anvil member and staple holding assembly for stapling. If the surgical stapling assembly is overloaded with tissue and clamped, the clamping force results in a displacement of the anvil member relative to the staple holding assembly in the general direction of the clamping force. The amount of displacement of the anvil member permitted by the resilient means is large enough to prevent excessive pressure on the tissue, but not so large that the anvil member is no longer sufficiently close to the staple holding assembly to perform its function of crimping the ends of the staples driven from the staple holding assembly.
