Apparatus and method of extracorporeally applying and locking laparoscopic suture and loop ligatures
First Claim
1. A ligator device for extracorporeally manipulating both suture strands of a slip knot and pushing hitch knots, comprising:
- a shaft having a proximal end and a distal end, the shaft further comprising;
an aperture at its distal end;
a first side aperture located between the distal end and the proximal end;
an internal channel connecting the distal end aperture and the first side aperture; and
the distal end aperture, first side aperture and internal channel sized such that at least one suture strand can be slidably inserted into the distal end aperture and exit the first side aperture.

Abstract
A suture applier instrument for tying suture and loop ligatures in laparoscopic excisional procedures such as LAVH, tubal ligation, salpingectomy, cophorectomy and appendectomy; in the repair of the fallopian tubes, uterus and ovaries; and in retropubic colposuspension using locking slip knots; and an efficient extracorporeal method to effectively lock them. The slip knot is held at the tip of the suture applier instrument and is kept in position on the target tissues while its two suture strands are operated extracorporeally, tying the loop ligature with one of the strands and locking or tightening the knot itself with the other. Additional hitch knots may be introduced and tied after the slip knot has been applied, using the same instrument. New knots, spool for pretied knot sutures and knot tying techniques for use with the suture applier are presented.

32. A spool device for mounting a knot on a ligator device, further comprising:
a hollow cylindrical flexible spool, the spool further comprising; means on said spool to retain the strands of a suture; wherein the flexible spool is compressible such that the outer diameter of the spool can be reduced. - View Dependent Claims (33, 34)
