Multipurpose bone fiber tube incision knife and incision device

In one aspect, the invention provides a multipurpose bone fiber tube incision knife which comprises a knife body. The cutter body comprises a first end and a second end in the extending direction of the cutter. An edge blade facing the outside of the cutter body is formed on the end portion of the first end, and a protruding portion is formed. And a bending part is formed by bending at a set bending angle at a position, which is a set distance away from the side blade, of the first end. Under the combined action of the side blades and the protruding parts, local stress is easier, the excision process is more accurate and rapid, the wound area is small, and rehabilitation is easier. Meanwhile, the invention further provides a multipurpose bone fiber tube cutter. 本发明一个方面，提供了一种多用途骨纤维管切开刀，其包括：一个刀体。刀体沿刀延伸方向包括一个第一端和一个第二端。在第一端的端部形成一个朝向刀体外部的边刃且形成一个凸出部。在第一端距离边刃一个设定距离的位置上以一个设定弯折角度弯折形成一个弯折部。在边刃且和凸出部的共同作用下，更易对局部受力，切除过程更为准确、迅速，创口面积小，更易康复。同时，本发明还提供了一种多用途骨纤维管切开器。
