Abstract
Abstract A suturing instrument (10) is disclosed having a handle (11) with finger rings (16, 17), a surgical needle (14) pivotably mounted to the handle, and grasping jaws (12, 13) for securing the pivotal position of the needle. The needle has a suture receiving recess (26) and a latch (27) pivotable between a closed position overlying the recess and an open positioning unobstructing the recess.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
144 words
A suturing instrument comprising an elongated handle having a grip end and a support end; a surgical needle having a tissue piercing tip and an elongated shaft extending from said piercing tip, a portion of said elongated shaft adjacent said tissue piercing tip being aligned along a longitudinal axis extending through said tissue piercing tip; pivot means including a pivot pin extending from said elongated shaft for pivotably mounting said surgical needle to said handle support end for pivotal movement of said shaft portion and piercing tip generally along a radial array of positions about said pivot means; holding means for releasably holding said needle in selected pivotal positions with respect to said handle; and locking means for locking and releasing said releasably holding means, whereby the surgical needle may be pivoted to different radial positions for tissue piercing movement of the surgical needle.
Claim 2
Dependent Claim
144 words
A suturing instrument comprising an elongated handle having a grip end and a support end; a surgical needle having a tissue piercing tip and an elongated shaft extending from said piercing tip, a portion of said elongated shaft adjacent said tissue piercing tip being aligned along a longitudinal axis extending through said tissue piercing tip; pivot means including a pivot pin extending from said elongated shaft for pivotably mounting said surgical needle to said handle support end for pivotal movement of said shaft portion and piercing tip generally along a radial array of positions about said pivot means; holding means for releasably holding said needle in selected pivotal positions with respect to said handle; and locking means for locking and releasing said releasably holding means, whereby the surgical needle may be pivoted to different radial positions for tissue piercing movement of the surgical needle.
Claim 3
Dependent Claim
33 words
The suturing instrument of claim 1 wherein said surgical needle has a thread receiving recess and a latch pivotal between a closed position overlying said recess and an open position distal said recess.
Claim 4
Dependent Claim
38 words
The suturing instrument of claim 1 wherein said locking means comprises spring means for biasing said pivot pin and camming means for forcing said pivot pin in a direction opposite to the biasing force of said spring means.
Claim 5
Dependent Claim
13 words
The suturing instrument of claim 3 wherein said holding means comprises a detent.
Claim 6
Dependent Claim
36 words
The suturing instrument of claim 4 wherein said detent comprises an annular array of teeth coupled to said needle sized and shaped to mate with another annular array of teeth coupled to said handle support end.
Claim 7
Dependent Claim
33 words
The suturing instrument of claim 5 wherein said surgical needle has a thread receiving recess and a latch pivotal between a closed position overlying said recess and an open position distal said recess.
Claim 8
Dependent Claim
29 words
The suturing instrument of claim 1 wherein said holding means comprises a pair of grasping jaws movable between a position grasping said needle and a position releasing said needle.
Claim 9
Dependent Claim
19 words
