Abstract

The invention is composed of a set consisting of a handheld nail trephine that utilizes a sharp pointed conical burr that enables the operator to penetrate and make small circumscribed holes on a human finger or toenail to decompress the buildup of fluids resulting from previous blunt trauma as well as a hand restraint assembly to secure the hand to be operated on for the duration of the surgical procedure. The attachment to the trephine which enables it to create small circumscribed holes on the surface of the human nail is an acutely sharp pointed conical burr that allows for the quick removal of nail tissue and yet controlled penetration of the nail itself. The hand restraint assembly is a rigid flat hard board on which a silhouette of the human hand is imprinted as well as pegs have been mounted through perpendicular to its flat surface so as to guide the placement of and aid in the immobilization of the hand of the patient. The strategic placement of straps on the hand restraint board across the outstretched fingers and wrist effectively secures the patient's hand onto the board's flat surface and thereby minimizes the risk of inadvertent movement thereof. A mirror image of the silhouette as well as the placement of the pegs and straps is provided for on the reverse side of the hand restraint board in such a way as to allow the opposite hand of the patient to be so restrained as needed. The entire device set is designed to allow for simple and portable operation and inexpensive manufacture. A method of use is also described herein.
