Abstract
Abstract An improved surgical ligating instrument has been invented. The improvement comprises crimping means having canted jaws and advancing means having a clip actuator, said actuator having a first and a second pawl in alternate relationship. A surgical ligating instrument has also been invented. The instrument comprises a. a housing having force activating and translating means; b. loading means having an injector, the terminal end adjacent a single clip; c. advancing means having a pair of aligned members, the initial end of said members contained in said housing and the terminal end containing jaws; a clip actuator rotatably mounted adjacent the initial end of said jaws; a spring, a pusher at the terminal end of said spring, and a plurality of clips, the rearmost clip adjacent said pusher and the frontmost clip contained by said actuator; and d. crimping means having a crimp bar. Another improved surgical ligating instrument has also been invented. The other improvement comprises a housing in substantial parallel alignment with a clip loading, advancing and crimping means.

Claim 6
Dependent Claim
202 words
A surgical ligating instrument comprising a. a housing having a first and a second force activating and force translating means to effect a first and a second force, respectively; b. loading means having an injector, the initial end of said injector adjacent said first translating means and the terminal end adjacent a single clip; c. advancing means having a pair of aligned members, each member containing an external and an internal slot, the initial end of said members contained in said housing and the terminal end containing jaws; a clip actuator rotatably mounted adjacent the initial end of said jaws, said actuator having a first and a second pawl in alternate relationship; a spring, the initial end contained in said housing, a pusher at the terminal end of said spring, and a plurality of clips, the rearmost clip adjacent said pusher and the frontmost clip contained by said actuator, said spring, pusher and clips contained by the internal slots of said members, and said injector adjoining the external slots; and d. crimping means having a crimp bar, the initial end adjacent said second translating means and the terminal end adjacent said jaws, said crimp bar holding said injector on said external slots.
Claim 7
Dependent Claim
202 words
A surgical ligating instrument comprising a. a housing having a first and a second force activating and force translating means to effect a first and a second force, respectively; b. loading means having an injector, the initial end of said injector adjacent said first translating means and the terminal end adjacent a single clip; c. advancing means having a pair of aligned members, each member containing an external and an internal slot, the initial end of said members contained in said housing and the terminal end containing jaws; a clip actuator rotatably mounted adjacent the initial end of said jaws, said actuator having a first and a second pawl in alternate relationship; a spring, the initial end contained in said housing, a pusher at the terminal end of said spring, and a plurality of clips, the rearmost clip adjacent said pusher and the frontmost clip contained by said actuator, said spring, pusher and clips contained by the internal slots of said members, and said injector adjoining the external slots; and d. crimping means having a crimp bar, the initial end adjacent said second translating means and the terminal end adjacent said jaws, said crimp bar holding said injector on said external slots.
Claim 8
Dependent Claim
13 words
An instrument of Claim 4 wherein said first activating means is a trigger.
Claim 9
Dependent Claim
31 words
An instrument of Claim 5 Wherein said first translating means is a sector gear on the terminal end of said trigger and a rack on the initial end of said injector.
Claim 10
Dependent Claim
34 words
An instrument of Claim 6 wherein said first translating means has at least one reduction gear such that said sector gear meshes with said reduction gear, and said reduction gear meshes with said rack.
Claim 11
Dependent Claim
72 words
An instrument of Claim 6 wherein said injector has holding means, said holding means comprising a pin on the initial end of said injector and a rotatable pawl contained in said housing, the distance between said pin and rotatable pawl about equal to the travel of a single clip adjacent the terminal end of said injector to said jaws whereby said injector is held adjacent to said single clip in said jaws.
Claim 12
Dependent Claim
