Embodiment

Embodiment one：

Illustrate present embodiment with reference to Fig. 1,2,3,4,5,6, the utility model is related to a kind of scissors, in particular It is that a kind of tissue damage is cut, including scissors main body I 1, chute 2, connector 3 and scissors main body II 4, serve not only as and wipe out brokenly Tissue is damaged, and blood in tissue can be discharged, it is to avoid blood splash.

Scissors main body I 1 include cutting edge 1-1, groove 1-2, conical baffled 1-3, cut handle 1-4, leakage fluid dram 1-5, through hole 1-6 and Drainage pipe 1-7, cutting edge 1-1, groove 1-2 and conical baffled 1-3 are arranged at the one end for cutting handle 1-4, and cutting edge 1-1 is with cutting handle 1- 4 be an entirety, and conical baffled 1-3, which is welded on, to be cut on handle 1-4, and conical baffled 1-3 is located above groove 1-2, taper gear Plate 1-3 effects are a conical surface will to be connected between Drainage pipe 1-7 outer wall and cutting edge 1-1, prevent from causing tissue breach uneven The even situation in turn resulting in Lou blood occurs.Leakage fluid dram 1-5 is arranged on the other end for cutting handle 1-4, and through hole 1-6, which is arranged on, cuts handle 1-4 Centre position, and through hole 1-6 hole wall is welded on Drainage pipe 1-7 inwalls, and Drainage pipe 1-7, which is arranged on, cuts handle 1-4 Inside, is interconnected between Drainage pipe 1-7, groove 1-2 and leakage fluid dram 1-5.

Connector 3 is interference fitted including rotating shaft 3-1 and cap 3-2, cap 3-2 and rotating shaft 3-1.

Chute 2 runs through the through hole 1-6 in scissors main body II 4, scissors main body I 1 and the rotating shaft 3-1 in connector 3 gap Coordinate, chute 2 and rotating shaft 3-1 is interference fitted.In use, first being vised the blood vessel beside linked groups with haemostatic clamp, then it will cut Direction of the knife main body II 4 along chute 2 slides into position shown in Fig. 2, then by the cutting edge 1-1 piercing groups in scissors main body I 1 Knit, until conical baffled 1-3 is submerged in tissue, i.e., groove 1-2 submerges tissue, now the blood in tissue enters from groove 1-2 Drainage pipe 1-7, finally flows out from leakage fluid dram 1-5, it is to avoid the situation of blood injection occurs in tissue, finally by scissors main body II 4 push back to the position shown in Fig. 1, and tissue is sheared.Scissors main body I 1 can be manufactured by 3D printing.
