Abstract

A quick loader and associated method for a surgical suturing instrument of the type having at least one ferrule receiving chamber and a suture receiving passage, includes a loader body having a recess formed therein for receiving an end of a surgical suturing instrument, a seat adjacent the recess for releasably holding at least one ferrule-tipped end of a suture in the seat, the seat being aligned and adjacent to a ferrule receiving chamber in the suturing instrument when the instrument is positioned in the recess, for permitting the transfer of the ferrules from the seat on the loader into the ferrule receiving chamber.

Claims

1. A quick loader for a surgical suturing instrument of the type having at least one ferrule receiving chamber and a suture receiving passage, comprising:

a loader body having a recess for receiving an end of a suturing instrument;

a seat adjacent the recess for releasably holding at least one end of a suture having a ferrule attached thereto, the seat being aligned with and adjacent to the ferrule receiving chamber in the suturing instrument when the end of the instrument is positioned in the recess for permitting the transfer of the ferrule from the seat on the loader and into the ferrule-receiving chamber.

2. The quick loader of claim 1 comprising a flexible tube received in the loader body and holding a length of suture.

3. The quick loader of claim 2 comprising a channel in the loader body the channel being aligned with the suture receiving passage in the surgical suturing instrument when the instrument is in the recess to permit the entry of an end of the tube tough the channel and into the suture receiving passage.

4. The quick loader of claim 1 comprising a slidable clip on the loader body for retaining a surgical suturing instrument in the recess.

5. A method of loading a suture in a surgical suturing instrument of the type having at least one ferrule receiving chamber and a suture receiving passage, comprising the steps of:

positioning an end of the surgical suturing instrument in a chamber of a quick loader body carrying at least one end of a suture having a ferrule attached thereto in a seat aligned with and adjacent to the ferrule receiving chamber;

inserting a flexible tube carrying a loop of the suture into and through the suture receiving passage;

withdrawing the flexible tube, leaving the loop of the suture in place in the suture receiving passage; and

transferring the end of the suture having a ferrule attached into the ferrule-receiving chamber.

6. The method of claim 5 in which the transferring step comprises pulling on the suture loop for drawing the ferrule from the seat and into the aligned ferrule receiving chamber to seat the ferrule in the ferrule receiving chamber.

7. The method of claim 5 comprising securing the quick loader body to the end of the surgical suturing instrument.

8. The method of claim 7 in which the securing step comprises sliding a clip on the quick loader body to a securing position.

9. The method of claim 5 comprising the additional step of removing the end of the surgical suturing instrument from the chamber of the quick loader body.

10. A method of loading a suture into a suturing instrument comprising the steps of:

loading a center loop of the suture into a flexible tube;

inserting the flexible tube into one end of a suture receiving passage in the suturing instrument and out a second end; and

pulling the tube off of the center loop of the suture through the second end.
