Abstract

A suture passer comprises a longitudinally extending hollow cannula having a central passage slidingly receivable of a surgical suture; a manually graspable handle connected to the hollow cannula for manipulation thereof, the handle having an upper surface; first guide means, connected to the upper surface of the handle, proximate a distal end of the handle for releasably, guidingly, holding the surgical suture; second guide means, connected to the upper surface of the handle, proximate to the first guide means, for releasably, guidingly, holding the surgical suture. The suture passer can be provided in a kit, for use in the suturing of internal tissue, along with a cannula bender, various hollow surgical needles and surgical suture material. The suture passer finds particular use in the suturing of internal tissues which are at least partially accessible through a body cavity, e.g. arthroscopic surgery.

Claims

1. A suture passer comprising:

a longitudinally extending hollow cannula having a central passage slidingly receivable of a surgical suture;

a manually graspable handle adapted to engage said hollow cannula for manipulation thereof, said handle having a distal end, a proximal end, and an intermediate portion;

first suture guide means formed by a first body portion of said handle proximate to the distal end of said handle and having a channel therethrough for guidingly holding the surgical suture;

second suture guide means formed by a second body portion of said handle proximal to said first suture guide means and having a channel therethrough for guidingly holding the surgical suture; and

said intermediate portion having an exposed surface for supporting the surgical suture, the exposed surface being disposed between the first and second body portions and configured to expose the surgical suture.

2. A suture passer according to claim 1 further comprising means for disengaging said cannula from said handle.

3. A suture passer according to claim 1 wherein said hollow cannula includes a proximal portion, and further wherein said proximal portion of said cannula is receivable within a first bore formed in the first body portion of said handle, the bore terminating at a proximal opening adjacent to said exposed surface of said handle intermediate portion between said first and second body portions.

4. A suture passer according to claim 1 wherein said cannula is sharply pointed at a distal end thereof.

5. A suture passer according to claim 4 wherein said cannula is rounded off at a heel of the distal end so as to minimize the possibility of damaging suture during a tissue piercing operation.
