Kalt with catch Needle Holder is a multipurpose microsurgical instrument typically used during approximation and closure procedures. The handle of this needle holder varies from the double spring bow of the standard Castroviejo handle. The needle holder handle is flat, but forms a triangular design with a thumb release. The jaws are still delicate and cross serrated. SMS permanently bonds tungsten carbide inserts to the instrument, which maximizes control and precision. TC instruments are identified by gold handles. This product is straight with serrated tips and a length of 135 mm.
