Abstract

The invention relates to the field of orthopedic medical devices, and provides an adjustable costal cartilage cutter and an ear and nose surgical instrument. The adjustable costal cartilage cutter comprises a fixing frame and a knife holder, the knife holder is located above the fixing frame and connected with the fixing frame, and the knife holder is provided with a blade. The holder is providedwith a clamping assembly for fixing the cartilage and a tray for placing the clamping assembly, and the tray is provided with a sliding slot perpendicular to the direction of the blade. The clamp assembly is provided with a slider that cooperates with the chute, the knife holder being movable in a direction toward or away from the mount and cutting the cartilage within the clamp assembly. Throughchanging the position of the cartilage to be cut relative to the blade by moving the cartilage to be cut, a blade can cut cartilage of any desired thickness, which is more operative. The ear and nosesurgical instrument includes the above-described adjustable costal cartilage cutter, which can cut cartilage quickly and cut quickly. One blade is capable of cutting cartilage of any desired thickness, which is easier to operate.
