Abstract: The authors propose a novel concept for less invasive hemostatic forceps. The proposed hemostatic forceps employ superelastic shape memory alloys that enable one to maintain the clamping pressure within a safe range. In this paper, the basic design of these hemostatic forceps is described. The validity of the concept is demonstrated by experimental results using a prototype.

Keywords: Shape memory alloy, superelasticity, atraumatic hemostatic forceps, less invasiveness
