A laparoscopic ligation clip applicator for automatically applying a plurality of ligation clips includes a handle assembly having an actuator, an elongated shaft connected to the handle assembly, and an actuating mechanism disposed within the shaft. The actuating mechanism includes a clamp for engaging a first piece of the ligation clip and a slidable driver for driving a second piece of the ligation clip relative to the first piece. The actuating mechanism also includes a hold for preventing rearward movement of the ligation clips, and an advancer for sequentially feeding the ligation clips. A slidable cam, operably connected to the handle assembly, actuates the clamp, the driver and the advancer.

A malleable, bioabsorbable polymeric staple includes a back span with two legs depending perpendicularly therefrom that are deformed toward each other initially and then upwardly toward the back span such that end points on each leg extends to the side and past the back span. The staple has a noncircular cross-sectional shape. A surgical staple-deforming anvil for deforming the staples has a staple-receiving face formed with a pair of elongated, non-collinear pocket-like depressions each having an entry end lying on a longitudinal axis parallel to the back span of the staple, and an exit end. The respective exit ends of the pocket depressions are located on opposite sides of the longitudinal axis. Accordingly, the legs of a staple driven toward the anvil and received in the pocket depressions are initially bent toward each other and then steered upwardly toward opposite sides of the back span.

A two-part surgical ligation clip includes a track having two substantially symmetrical arms and a clip for slidably receiving the track. The symmetrical arms are connected together at a proximal end to form an apex and have spaced-apart tips at a distal end with first complementary surface. The track also includes a connector connected to the apex and having a second complementary surface. The clip has an extended slot for slidably engaging the track and distal end tips for receiving the connector. A distal end of the clip has a first contour surface for engaging the first complementary surface on the track and locking it in a closed position and a second contour surface for engaging the second complementary surface on the track and locking it in an open position.

A malleable, bioabsorbable polymeric staple includes a back span with two legs depending perpendicularly therefrom that are deformed along an arcuate path toward each other initially and then upwardly toward the back span such that end points on each leg extend through a gap formed between an underside of the back span and a bend in an opposite leg. A surgical staple-deforming anvil for deforming the staples has a staple-receiving face formed with a pair of guiding path depressions each having an entry end lying on a longitudinal axis parallel to the back span of the staple, and an exit end. The guiding paths are arcuately shaped and form a groove curving and crossing each other approximately at the longitudinal axis. Accordingly, the legs of a staple driven toward the anvil and received in the guiding paths are initially bent toward each other and then steered upwardly and along the horizontally curved path toward the gap formed between the back span and the bend in the opposite leg.

First and second metal blades made from uniform thickness stock are fashioned into scissors which may be disposable suture scissors. Each of the blades is stamped from sheet metal, they are pivoted together, and handles extend in the opposite direction from cutting edges on the blades. Resilient means is provided by the handles being resilient and stop means are provided to limit the closed position of the cutting edges to prevent overriding, namely overclosing, of the cutting edges. The stop means includes first and second stop surfaces integral with the first and second blades, respectively. The stop surfaces are close to the pivot relative to the length of the handles, the blades have only frictional opposition to movement until the stop surfaces engage, and then the subsequent stressing of the resilient means establishes a cushioned stop of movement of the handles without any further movement of the cutting edges past the fully closed condition. The foregoing abstract is merely a resume of one general application, is not a complete discussion of all principles of operation or applications, and is not to be construed as a limitation on the scope of the claimed subject matter.

A clamp for securing in a fluid proof manner a wafer type butterfly valve to the coupling flange of a pipe. Wafer type butterfly valves are inserted between the flanges of two aligned pipes and are retained in position by bolts connecting the two flanges and engaging around the apertureless wafer flange of the valve body. The clamp of the invention is designed to secure such a wafer type butterfly valve to a pipe flange of the end of a pipe line to form a dead end pipe line. The clamp is made of two separate clamp members which are mirror images of each other. Each clamp comprises a flat arcuate flange section adapted to overlap a flange portion of the valve body. Said flange section has bolt receiving holes adapted to the aligned with half the number of bolt receiving apertures of the pipe coupling flange. Each clamp member further includes a collar section rigid with the flange section and perpendicular thereto. The collar section has portions adapted to come in close relation with the outer edge of the wafer flange of the valve body and is provided with a series of equally spaced indents for clearing the bolt receiving holes of the flange section. The collar sections serve to easily center the clamp with respect to the valve body and pipe flange and to further maintain said valve body against rotation. Preferably the bolt receiving holes in the flange section of each clamp member are threaded to eliminate the use of nuts.
