Abstract

A suturing device consists of a needle and a turning mechanism that drives the needle. A handle of the device drives the turning mechanism. The device receives suturing material needed for suturing tissue; and a surgeon may operate it by squeezing the handle. This action may move the needle from zero to 360 degrees.

Claims

1. A suturing apparatus comprising a generally elongate body with a rotatable needle portion having a curved end disposed at a distal end of the body and a handle portion at a proximal end, the handle portion including first and second parts, the first part being moveable with respect to the second part to rotate the needle portion, the handle portion supporting suturing material and the elongate body defining a bore that receives the suturing material and directs it through the body from the proximal end to the distal end and out of the curved end of the needle portion.

2. The apparatus of claim 1, wherein the body includes a tube portion with one end rotatably mounted to the handle portion, the tube portion supporting the needle portion which extends from inside the tube portion and outwardly of it.

3. The apparatus of claim 2, wherein the tube portion lies rotatably mounted to the first part of the handle portion, a pinion secured to the tube portion cooperates with a rack disposed on the second part of the handle portion to translate the relative movement of the first and second parts into rotation of the tube portion.

4. The apparatus of claim 3, wherein the handle portion includes a spool rotatably mounted to the first part of the handle portion for supporting the suture material.

5. The apparatus of claim 1, wherein the curved end of the needle portion has a semi-circular configuration and a sharpened tip cut at an acute angle outwardly and rearwardly from the inner side of the semi-circular part of the middle portion.

6. A suturing apparatus comprising:

a handle with first and second portions secured together for relative movement to one another;

a tube rotatably mounted to the handle and extending outwardly of the handle;

a needle secured to the tube and including a curved end portion;

the handle supporting suture material;

the tube and needle defining bores through which the suture material extends.

7. The apparatus of claim 6, wherein the tube portion lies rotatably mounted to the first part of the handle portion, a pinion secured to the tube portion cooperates with a rack disposed on the second part of the handle portion to translate the relative movement of the first and second parts into rotation of the tube portion.

8. The apparatus of claim 6, wherein the curved end of the needle portion has a semi-circular configuration and a sharpened tip cut at an acute angle outwardly and rearwardly from the inner side of the semi-circular part of the middle portion.

9. The apparatus of claim 7, wherein the handle portion includes a spool rotatably mounted to the first part of the handle portion for supporting the suture material.
