Abstract
Abstract The disclosure is of a suturing clamp in which the jaws are moved toward each other to a pre-set position wherein the flesh is firmly, but not too tightly clamped. A bifurcated needle is moveably carried on one of the jaws and a length of suture is extended from a bobbin on the clamp to a grip at the end of the jaw. After the pre-set clamping position is reached, further operation drives the needle across the space between the jaws to carry a length of suture with it.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
197 words
A surgical suture applicator comprising: a first lever including a first jaw arm thereon; a second jaw arm; a pivotal connection between said first lever and said second jaw arm; an actuator lever; means releasably connecting said actuator lever to said second jaw arm to transmit pivotal movement thereto; a needle slidably carried in said second jaw arm from a retracted position within said second jaw arm to a suturing position extended therefrom toward said first jaw arm; a needle-receiving passageway in the end of said first jaw arm; a supply of suture on said second jaw arm; means on the end of said second jaw arm outward of said needle for gripping a length of suture from said supply across the path of said needle; means operable to disengage said releasable connecting means when said jaw arms have pivoted to a relatively closed position; and means then operable to restrain further relative movement between said jaw arms; means responsive to further pivotal movement of said actuator lever toward said first lever for moving said needle into said suturing position; and means on the end of said needle for grasping said length of suture during said movement.
Claim 2
Dependent Claim
197 words
A surgical suture applicator comprising: a first lever including a first jaw arm thereon; a second jaw arm; a pivotal connection between said first lever and said second jaw arm; an actuator lever; means releasably connecting said actuator lever to said second jaw arm to transmit pivotal movement thereto; a needle slidably carried in said second jaw arm from a retracted position within said second jaw arm to a suturing position extended therefrom toward said first jaw arm; a needle-receiving passageway in the end of said first jaw arm; a supply of suture on said second jaw arm; means on the end of said second jaw arm outward of said needle for gripping a length of suture from said supply across the path of said needle; means operable to disengage said releasable connecting means when said jaw arms have pivoted to a relatively closed position; and means then operable to restrain further relative movement between said jaw arms; means responsive to further pivotal movement of said actuator lever toward said first lever for moving said needle into said suturing position; and means on the end of said needle for grasping said length of suture during said movement.
Claim 3
Dependent Claim
16 words
The surgical suture application defined by claim 1 wherein: the end of said needle is bifurcated.
Claim 4
Dependent Claim
23 words
The surgical suture applicator defined by claim 1 including: a reel carrying said supply of suture rotatably carried on said second jaw arm.
Claim 5
Dependent Claim

The surgical suture applicator defined by claim 3 including: a magazine containing said reel and said suture gripping means releasably carried on said second jaw arm.
Claim 6
Dependent Claim
72 words
The surgical suture applicator defined by claim 1 including: a clamp slidably carried on said first jaw arm; spring means normally biasing said clamp across said passageway; a camming surface on said clamp engageable by said needle moving into said suturing position to retract said clamp against said spring means; and a gripping surface on said clamp to prevent withdrawal of a length of suture carried into said passageway by said needle.
Claim 7
Dependent Claim
49 words
The surgical suture applicator defined by claim 1 wherein said releasable connecting means comprises: a latch member carried on said second jaw arm engaging a surface on said actuator lever to form the connection therewith to transmit said pivotal movement through a predetermined angle toward said first jaw arm.
Claim 8
Dependent Claim
33 words
The surgical suture applicator defined by claim 1 wherein said needle moving means comprises: a pusher rod pivotally connected between said actuator lever and said needle and slidable along said second jaw arm.
Claim 9
Dependent Claim
34 words
The surgical suture applicator defined by claim 7 wherein: said needle is of arcuate configuration, and including: a complementary, arcuate slideway in the end of said second jaw arm Opening toward said needle-receiving passageway.
Claim 10
Dependent Claim
22 words
The surgical suture applicator defined by claim 1 wherein: said suture grasping means comprises a bifurcation at the end of said needle.
