Devices, apparatus, and methods of using a modified scalpel tool that is removable from a polyurethane mated sheath for use in carpal tunnel surgeries and the like. The modified scalpel tool has an elongated stem with a flat blade at the distal end and an elongated handle at the proximal end. The sheath has a cavity for allowing the elongated blade to be inserted therein, two slots to receive two metal studs and a handle at its proximal end. The flat blade tool-polyurethane when combined (mated) produces a stable configuration that allows motion in only one rotational plane and with an arc of 90-95 degrees. |
