Abstract

A needle cartridge is adapted to be attached to a receiver on a surgical suturing device. The cartridge comprises an arced needle having a leading end, a trailing end, and a length of suture. A body has a track receiving the needle and defining a circular path. A needle driver is operable to rotate the needle along the circular path. A cover captures the needle in the track. A cage engages and retains the needle cover against the body. The cage may slide relative the body to disengage with a portion of the cover allowing the cover to deflect and release the needle from the track.

Claims

1. A needle cartridge adapted to be attached to a receiver on a surgical suturing device, the cartridge comprising:

an arced needle having a leading end, a trailing end, and a length of suture;

a body having a track receiving the needle and defining a circular path;

a needle driver operable to rotate the needle along the circular path;

a cover capturing the needle in the track, the cover having a pair of distally projecting arms; and

a cage that engages and retains the distally projecting arms of the needle cover against the body;

wherein the cage slides relative the body to disengage with the distally projecting arms of the needle cover allowing the arms to deflect and release the needle from the track.

2. A needle cartridge adapted to be attached to a receiver on a surgical suturing device, the cartridge comprising:

an arced needle having a leading end, a trailing end, and a length of suture;

a body having a pair of distally projecting arms and a track receiving the needle and defining a circular path;

a needle driver operable to rotate the needle along the circular path across the body arms;

a cover capturing the needle in the track, the cover having a pair of distally projecting arms aligned with the body arms;

a cage slideable relative the body between a distal position where the cage constrains the cover arms against the body arms to capture the needle in the track, and a proximal position where the cage disengages from the cover arms allowing the needle to eject from the track, wherein the cover arms deflect to eject the needle.

3. The needle cartridge of claim 2, wherein the body and cover arms define a generally U-shaped distal end, and the cage comprises a U-shaped distal end that aligns with the U-shaped distal end when the cage is in its distal position.
