ABSTRACT:
A disposable suture cutter formed as a resilient member from a single piece of molded material having two opposed free ends to be held between the fingers and thumb. One free end is shaped for insertion in cutting position under a suture without any lateral motion. A suture-retaining groove is positioned on the insertable free end for holding the suture transverse the free end. A cutting blade is attached to the other free end of the resilient member for movement transversely and downwardly relative to the axis of the suture held in the suture-retaining groove. A guide groove is provided on the insertable free end so as to prevent lateral motion of the cutting blade as it is moved across the suture. When operated, the suture cutter slices the suture held in the groove without additional motion of the free insertable end.
