Suture knot pusher

DETAILED DESCRIPTION Key Words and Definition Intertwine--when two free ends of the suture material are looped over one another once or twice.
Throw--one or more intertwine.
Knot--two or more throws laid in succession on top of each other and finally tightened and secured.
Conventional Knots used in Surgery Surgeon's knot--two intertwines delivered first to the surgical site with a `holding` effect thus preventing the loops from disentanglement.
Slipknot--a knot which allows the loop to tighten when one strand is drawn.
Square knot--two throws run down in succession to the surgical site, one sitting on top of the first and tightened.
This knot is the most desirable in securing tissues because once tightened it remains fixed and unyielding to applied pressure, like the internal pressure of blood vessel or opposing tissues.
Intracorporeal--inside body cavity Extracorporeal--outside body cavity The Video Assisted Minimally Invasive Laparoscopic Surgery is a new surgical technology which has completely changed the operative approach to some problems encountered inside the body cavity where one half inch incisions on the abdominal or chest walls are used instead of the traditional or open technique of five to six inches incisions to enter the cavity.
In the new laparoscopic surgical procedures, it requires the use of long slender instruments to reach the surgical sites by manipulating and guiding said instruments extracorporeally.
Because of the limited access to the surgical site when performing laparoscopic surgery, devices like the present invention are developed to help facilitate knot-tying thus an object of the present invention is to provide a means by which these throw-knots are delivered or run down smoothly through the trocar-instrument port and finally tightened and secured at the surgical site.
In addition to the above throw-knot delivery system, a method is developed in which several throws usually three or four, spaced 1 inch apart and fashioned extracorporeally on the two strands of the suture or ligature previously anchored at the surgical site
