Abstract

In a needle inserter with a needle protector for surgical suturing instruments, including a needle insertion structure having a handle part at one end and a needle mounting part at the other end, a slot is disposed in a needle mounting part for engaging therein a suturing needle. Means are provided for placing the needle inserter onto a jaw of a suturing instrument such that the needle can be locked with the jaws of the suturing instrument, which then, upon compression of the handle part, can be removed. The protector, which is installed on the needle inserter by a manufacturer, holds the needle in its proper position in the needle inserter and covers the needle tip to prevent displacement of the needle and injuries to persons installing the needle in the suturing instrument.

Claims

1. A needle inserter with a needle protector for surgical suturing instruments, comprising:

a needle insertion structure having a clothesline clip-like handle part at one end and a mounting part at the opposite end, said mounting part having longitudinal slots with an internal groove disposed therebetween, one of said slots, that is the walls defining said one slot, having a curved end and a predetermined width corresponding to the space between two jaws of a suturing instrument when disposed in a parallel closed position, and the other of said slots and said internal groove being wedge-shaped so that said needle inserter can be pushed fully onto a correspondingly shaped jaw of said suturing instrument, a suturing needle received, and engaged in, said one slot so as to be disposed at the curved end thereof in a predetermined position, a needle protector with a grasping end and a T-shaped front part with a web adapted to be received in said one slot and having an end with an extension projecting over the tip of a suturing needle disposed in said needle insertion structure when said needle protector is in place on said needle insertion structure, said web, said protector and said needle inserter consisting of an elastic plastic material, which permits the parts to be molded and which also permits resilient engagement of said needle in said first slot, but permits removal of said needle when said handle part of said needle inserter is compressed.

2. A needle inserter according to claim 1, wherein said needle insertion structure and said needle protector are interconnected by a string.

3. A needle inserter according to claim 2, wherein the engagement of said needle in said slot is sufficiently strong so that the needle will not fall out of said slot when said handles are compressed but that, with the handles compressed, a predetermined force is needed to remove the needle insertion structure from the needle when the needle is installed in a suturing instrument.

4. A needle inserter according to claim 3, wherein said needle protector web has, adjacent said projection, a section which is inclined toward said handle portion in adaptation to a bent end part of a suturing needle.

5. A needle inserter according to claim 4, wherein a compression spring is disposed between the two handles of said needle insert structure.
