US Patent:

46467408, Mar 3, 1987

Filed:

Feb 23, 1981

Appl. No.:

6/237465

Inventors:

Rudolph Peters - Oakland CA
Ronald L. Peters - Oakland CA
William Taylor - Oakland CA

Assignee:

Edward Weck & Co., Inc. - Research Triangle Park NC

International Classification:

A61B 1712

US Classification:

128325

Abstract:

A device for applying a plurality of hemoclips to blood vessels and the like includes a longitudinally disposed frame having a pistol grip and an opposed trigger lever extending from the proximal end thereof. A narrow, internal passageway extends the length of the frame, from a loading opening at the proximal end to a fixed lower jaw at the distal end of the frame. A plurality of U-shaped hemoclips is disposed in the passageway with the points thereof extending toward the distal jaw portion. An upper jaw extends from a clevis member which straddles the frame and is pivotally joined to an upper medial portion thereof. The trigger lever is pivotable to cause the clevis member to pivot upwardly and the upper jaw to close upon the lower jaw to crush a hemoclip disposed therebetween. A piston resiliently biased in the internal passageway urges the hemoclips toward the jaw portion, and a feed release lever is disposed at the proximal end of the passageway to discharge a hemoclip from the passageway to the jaw portion with each full actuation of the upper jaw.

International Classification:

A61B 1712

US Classification:

128325

Abstract:

A tool for storing dispensing, and applying hemostatic clips includes a shell-like housing, and a pair of ring-handle actuating levers extending therefrom. An elongated dispensing and applying portion extends longitudinally from the housing, and includes a jaw strut extending fixedly from the housing with a pair of laterally opposed jaw members pivotally supported on a distal portion thereof. A channel-like jaw housing extends from the housing in longitudinally translatable fashion, and is received about the jaw strut and jaw members. A magazine member secured to the jaw strut stores a plurality of hemostatic clips in serial, end to end fashion, and is disposed to deliver the distal-most clip between the open jaw members. A feeder slide adjacent to the jaw strut is resiliently biased to urge the clip toward the distal end of the jaw members. Within the housing a shuttle block is disposed for longitudinal translation by squeezing of the levers.

International Classification:

US Classification:

Abstract:

A method and apparatus for storing and automatically dispensing and applying surgical staples in serial fashion includes a pistol-like tool having means for storing a large plurality of staples in parallel, stacked column fashion aligned along the longitudinal (barrel) axis of the tool. A form tool and an anvil tool extend longitudinally parallel to the axis, and are advanced in synchronism by actuation of a trigger lever. The form tool includes a pair of arms which impinge upon and rotate the legs of the staple about the web portion thereof to dispose the staple in a points-first dispensing orientation. The form tool advances the staple to the distal dispensing end of the tool, where it drives the staple into a portion of the anvil and crimps the staple thereabout. Release of the trigger causes an elevator member to separate the next distal staple inthe column from its column alignment into postion to be engaged by the anvil tool and form tool at the start of the subsequent dispensing cycle. A trigger actuation mechanism prevents release of the trigger lever until the dispensed staple is completely crimped in the tissue.
