Patent ID: 11350936

Abstract:
A spring suture for primary closure of surgical incisions includes a center spring hingedly connected at each end with surgical tape. In one embodiment, the tape is connected to the center spring through a tape clamp and pin hinge. In another embodiment, the tape is connected to the center spring through welding flanges attached to membrane hinges. In operation, when the spring suture is in place on a wound or incision line, the distal ends of the surgical tape relative to the center spring, in conjunction with the center spring, are adapted to produce closure forces along the incision line that are remote from the incision, enabling such forces to act through the thickness of the skin through shear force transfer and provide closure force at the dermal level of the skin that is initially applied at the epidermal level, thus overcoming the problem of skin inversion at incision line common to skin tapes of the prior art.
