This creation is a scalpel, which includes an extension rod, a pick lever and a blade. The pick lever is bent to extend on the extension rod. The end of the pick lever that is away from the extension rod is arc-shaped； the blade is located between the extension rod and the pick lever. Lever and pick lever. By protruding the arc-shaped end of the pick lever between the nerve and the ligament, the ligament can be separated from the nerve without hurting the nerve, and then the ligament can be slid to the edge of the blade for cutting. With the above structure, the author can enable the surgeon to perform the steps of pulling out the nerve and cutting the ligament together with one hand and without interruption, which can simplify the procedure of the operation and greatly reduce the operation time and the risk during the operation.本創作係手術刀，其包含一延伸桿、一挑撥桿及一刀片。挑撥桿彎折延伸於延伸桿，挑撥桿遠離延伸桿的一端的端部呈圓弧狀；刀片設於延伸桿與挑撥桿之間，刀片具有一刃部，刃部的兩端分別連接於延伸桿及挑撥桿。藉由以挑撥桿的圓弧狀端部突入神經與韌帶之間，即可不傷及神經地將韌帶與神經分離，隨後即可順勢將韌帶滑動至刀片的刃部藉以切割。本創作藉由上述結構可使執刀醫師能夠以單手且不間斷地一併進行撥離神經以及切割韌帶的步驟，可以更簡化手術的步驟，進而大幅降低手術的時間以及手術期間的風險。
