Abstract
A device is provided for severing the tails of a knot formed in sutures of a wide variety of cross-sectional dimensions which includes a housing, an electrical heating element forming at least a portion of a notch, guide means operably associated with the heating element and the housing, the guide means functioning to bring the tails of the knot into contact with the heating element and meams for electrically supplying power to the heating element.
Claims6
A device for severing the tails of a knot formed in sutures of a wide variety of cross sectional dimensions, comprising:
- (a) a housing;
- (b) a pair of spaced, opposed guides extending from said housing, said guides forming a slot having sufficient width to accommodate the largest cross sectional dimension of said sutures;
- (c) an electrical heating element positioned across said slot at an oblique angle forming a notch such that one side wall of said notch is formed from one of said guides and the other side wall of said notch is formed from said heating element;
- and
- (d) means for interruptibly supplying electrical power to said heating element.
A device for severing the tails of a knot tied in a surgical suture, which comprises a housing;
- a source of electrical power in said housing;
- a pair of electrically conductive members mounted on said housing operably associated with said source of electrical power and spaced from one another forming a slot wherein the side wall of at least one of said electrically conductive members forming said slot is shaped in a descending stepwise manner to accommodate surgical sutures of varying cross sectional dimensions;
- a resistance heater means connected to both of said conductive members and mounted on said conductive members at a mounting angle forming a notch such that a wide range of suture diameters will pass through said slot and means operably associated with said source of electrical power and said electrically conductive members to supply electrical power to said heater means.
