Suture cutter
First Claim
1. A suture cutter comprising:
- an elongated member and an elongated blade, said blade having a knife edge for shearing a suture and a back remote from said edge,said member having a depth and comprising an arm, an element, and a slot therebetween, said slot having a portion adapted to receive a suture but being too small to permit a knot in the suture to pass therethrough, andmeans connecting said member and said blade for relative movement therebetween in a direction substantially perpendicular to said elongated member and blade, said means enabling suture-shearing contact between said member and said blade such that said blade is relatively movable across said slot for cutting the suture so as to leave a stub on the side of the suture away from the tissue in which the suture is tied substantially equal in length to the depth of said member.

Abstract
A suture cutter comprising a member and a blade, said blade having a knife edge and a back remote from said edge, said blade being adapted to shearingly contact said member,
said member having a depth and comprising an arm, an element, and a slot therebetween, said slot having a portion adapted to receive a suture but being too small to permit a knot in said suture to pass therethrough, whereby shearing contact between said member and said blade cuts said suture leaving a stub on the side of said suture away from the tissue in which said suture is tied substantially equal in length to said depth.
Variations of the foregoing device are also disclosed, including forms in which the motion between the member and the blade is obtained by a scissor-like action as well as by a tweezer-like action; in addition, an embodiment wherein the handles or gripping area of the device is in a different plane from the working end. There is also disclosed a combination of the present invention with a surgical needle holder.
