Abstract
Abstract An improved surgical instrument is described. The instrument comprises a housing. The housing has a handle for activating a force, and a link for translating the force. The instrument also comprises a probe. The probe has jaws or an anvil for holding a single wound closure element, a movable crimp bar for crimping the single closure element in the jaw or anvil, the proximal end of the crimp bar being connected to the distal end of the link, a spring for advancing a plurality of wound closure elements, and an injector for loading a single wound closure element, from the plurality, into the jaws or onto the anvil. The improvement comprises the link indirectly connected to the spring and the injector to integrally effect the crimp bar, spring and injector. The surgical instrument can be a ligating instrument.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
120 words
A surgical instrument comprising A. a housing having I. a sole means for activating a force, and II. a link for translating said force; and B. a probe having I. means for holding a single wound closure element, II. a movable crimp bar for crimping said single closure element in said holding means, the proximal end of said crimp bar connected to the distal end of said link, III. means for advancing a plurality of wound closure elements, and IV. means for loading a single wound closure element, from said plurality, into said holding means, the improvement comprising said link indirectly connected to said advancing and loading means to integrally effect said crimp bar and said advancing and loading means.
Claim 2
Dependent Claim
120 words
A surgical instrument comprising A. a housing having I. a sole means for activating a force, and II. a link for translating said force; and B. a probe having I. means for holding a single wound closure element, II. a movable crimp bar for crimping said single closure element in said holding means, the proximal end of said crimp bar connected to the distal end of said link, III. means for advancing a plurality of wound closure elements, and IV. means for loading a single wound closure element, from said plurality, into said holding means, the improvement comprising said link indirectly connected to said advancing and loading means to integrally effect said crimp bar and said advancing and loading means.
Claim 3
Dependent Claim
13 words
An instrument of claim 1 wherein said crimp bar has a biasing member.
Claim 4
Dependent Claim
20 words
An instrument of claim 2 wherein said biasing member is a spring adjacent the proximal end of said crimp bar.
Claim 5
Dependent Claim
116 words
A surgical ligating instrument comprising A. a housing having I. a sole means for activating a force, and II. a link for translating said force; and B. a probe having I. a movable crimp bar for crimping a single ligating clip, the proximal end of said crimp bar connected to the distal end of said link, II. means for advancing a plurality of ligating clips, the distal end of said advancing means having a pair of jaws, and III. means for loading a single clip from said plurality into said jaws, the improvement comprising said link indirectly connected to said advancing and loading means to integrally effect said crimp bar and said advancing and loading means.
Claim 6
Dependent Claim
116 words
A surgical ligating instrument comprising A. a housing having I. a sole means for activating a force, and II. a link for translating said force; and B. a probe having I. a movable crimp bar for crimping a single ligating clip, the proximal end of said crimp bar connected to the distal end of said link, II. means for advancing a plurality of ligating clips, the distal end of said advancing means having a pair of jaws, and III. means for loading a single clip from said plurality into said jaws, the improvement comprising said link indirectly connected to said advancing and loading means to integrally effect said crimp bar and said advancing and loading means.
Claim 7
Dependent Claim
13 words
An instrument of claim 4 wherein said crimp bar has a biasing member.
Claim 8
Dependent Claim
20 words
An instrument of claim 5 wherein said biasing member is a spring adjacent the proximal end of said crimp bar.
