Abstract
Abstract A disposable suture cutter and needle holder for a suture needle having thread thereon has a supporting base for a foamed plastic needle holder. A cutting blade having foamed plastic disposed adjacent to it is also mounted on the supporting structure. In one embodiment the supporting structure is in the form of a bracelet having a reversely turned portion at one end. The cutting blade is embedded in the reversibly turned portion. In another embodiment, two truncated conical members are joined at one side of their edges and spaced at the opposite side. The cutting blade is disposed between the spaced edges. In still another embodiment, two conical members are spaced from each other by foamed plastic having diametrically opposite located slots therein. The cutting blade has cutting edges adjacent to each slot.
