K-Wires, Steinmann Pins, and Trocars

MCS product quality and grinding expertise means better surgical outcomes. Our ultra-sharp hollow point process minimizes insertion force and harder cutting edges equate to lower heat and minimal cell necrosis. Finally, our super smooth finishes ensure easy removal post-surgery.
