When an object is cut to form a bleeding port, the user can adjust the position of the surgical scissors 100 so that the first pressing sheet 15 corresponds to one end of the bleeding port, and the second pressing sheet 16 corresponds to the other end of the bleeding port. The first pressing sheet 15 and the second pressing sheet 16 press the two ends of the bleeding port together to stop bleeding of the bleeding port. For the connection of the second pressing sheet 16 and the first blade head 13, the second side 13b of the first blade head 13 is provided with a second clamping groove 13f, and the second blade head 14 is provided with a second fixing structure in the second clamping groove 13f. Part of the second pressing sheet 16 is inserted into the second clamping groove 13f, and the second fixing structure is fixed with the part of the second pressing sheet 16 inserted into the second clamping groove 13f to fix the second pressing sheet 16 in the second clamping groove 13f, thereby achieving installation of the second pressing sheet 16.

[0040] Optionally, for the second pressing sheet 16, please refer to Figure 1 In combination Figure 2 , the second pressing sheet 16 comprises a second flat portion and a second bent portion. The second flat portion is connected to the first handle 11, and the second bent portion is connected to the second flat portion. When the user presses the bleeding port through the second pressing sheet 16, the second bent portion abuts against the bleeding port. Optionally, the second pressing sheet 16 is L-shaped or arc-shaped.

[0041] In some embodiments, the second pressing sheet 16 is provided with a second medicine groove, and the surgical scissors 100 further comprises a second medicine hemostatic piece, which is arranged in the second medicine groove and at least partially protrudes from the second medicine groove. The part of the second medicine hemostatic piece protruding from the second medicine groove is used to abut against the bleeding port to hemostasis the bleeding port. Optionally, along the depth direction of the second medicine groove, the cross-sectional area of the second medicine groove gradually decreases. When the second medicine hemostatic piece is inserted into the second medicine groove, the second medicine groove has a squeezing effect on the second medicine hemostatic piece, so as to stably install the second medicine hemostatic piece on the second pressing sheet 16.

[0042] In some embodiments, please refer to Figure 1 In combination Figure 3 , the surgical scissors 100 further comprises a third pressing sheet 17 and a fourth pressing sheet 18. The second blade head 14 has oppositely arranged third and fourth sides 14a and 14b, the third pressing sheet 17 is arranged on the third side 14a, and the fourth pressing sheet 18 is arranged on the fourth side 14b. The first pressing sheet 15 and the third pressing sheet 17 are located on the same side, and the second pressing sheet 16 and the fourth pressing sheet 18 are located on the other side. When the first blade head 13 and the second blade head 14 are in the folded state, the first pressing sheet 15 and the third pressing sheet 17 can clamp the bleeding port to hemostasis the bleeding port, and the second pressing sheet 16 and the fourth pressing sheet 18 can also clamp the bleeding port to hemostasis the bleeding port.

[0043] In the embodiments of the present application, a surgical scissors 100 is provided, which comprises a first handle 11, a second handle 12, a first blade head 13, a second blade head 14 and a first pressing sheet 15. The first handle 11 and the second handle 12 are crossed and rotationally connected. The first blade head 13 is connected to one end of the first handle 11, and has oppositely arranged first and second sides 13a and 13b. The second blade head 14 is connected to one end of the second handle 12. The first pressing sheet 15 is arranged on the first side 13a. When the other end of the first handle 11 and the other end of the second handle 12 are driven, the first blade head 13 and the second blade head 14 can be switched between a folded state and an open state. The first pressing sheet 15 is used to press the bleeding port when the first blade head 13 and the second blade head 14 fold to cut an object to form a bleeding port, so as to hemostasis the bleeding port. Compared with the prior art, the user can press the bleeding port through the first pressing sheet 15, which further solves the technical problem of the inconvenience of replacing the hemostasis tool after cutting by the user.
