Ferrule holder with suture relief lobes
A surgical suturing instrument has a chamber for receiving and aligning a ferrule with a reciprocating needle. The chamber includes a plurality of protuberant concave and convex surfaces for positioning and aligning the ferrule within the chamber and the plurality of suture receiving chambers disposed between the aligning ridges for receiving a suture and preventing the suture from jamming the ferrule in the chamber.
1. A surgical suturing implement, comprising:
a) an elongated body;
b) a distal tip coupled to the elongated body, the tip defining:
1) a tissue gap across an upper portion; and
2) a ferrule receiving compartment having:
i) a ferrule receiving opening having three spaced apart surfaces for contacting an outside surface of a ferrule and aligning the ferrule within the opening;
ii) a suture receiving slot disposed between first and second adjacent ones of the three spaced apart surfaces;
iii) a first suture receiving chamber disposed between first and third adjacent ones of the three spaced apart surfaces; and
iv) a second suture receiving chamber disposed between second and third adjacent ones of the three spaced apart surfaces; and
c) a needle moveable within the elongated body and across the tissue gap in the distal tip to alignment within the ferrule receiving opening, but not within the first or second suture receiving chambers.
2. The surgical suturing instrument of claim 1 , wherein the three spaced apart surfaces comprise concave and convex surfaces.
3. The surgical suturing instrument of claim 2 , in which two of the spaced apart surfaces are concave surfaces and the third spaced apart surface is a convex surface.
4. The surgical suturing instrument of claim 1 , further comprising a moveable latch and wherein the distal tip further defines a compartment for the moveable latch such that the movable latch is movable through the first and second suture receiving chambers and into the ferrule receiving opening.
