Abstract
A skin biopsy system covers all aspects of the biopsy procedure from initial incision to final closure. The system includes a flexible closure consisting of 4 elongated rigid members interconnected by flexible hinges. The opening within the closure is initially diamond-shaped, approximating an ellipse, which is then deformed or pinched to a narrow linear opening when the wound is closed. Included with the system is a knife which interacts with the closure to yield a guided incision of constant depth. The path of the knife is guided by interference between the blade and the inside faces of the closure while the depth is limited by interference of the handle proximal the blade and the top faces of the closure.
