As shown in Figures 2, 3 and 4, the preferred embodiment of the vascular tissue hemostatic band for surgery of the present invention is suitable for urgently sheathing blood vessel tissue (not shown), thereby compressing the blood vessel to achieve hemostasis. purpose.

The vascular tissue hemostatic band 2 for surgery is in the form of a flat long strip and is made of a biodegradable medical material that is flexibly deformable, such as polydioxanone (polydioxanone), including one having a front The buckle head portion 3 of the side surface 31 and the rear side surface 32, and the sleeve portion 4 and the second extending from the buckle head portion 3 in the same manner are respectively protruded from the sleeve portion 4 in a zigzag manner. The side tooth portions 5 on the left and right sides and the rear tooth portion 6 projecting from the rear side surface 32 of the sheath band portion 4 are formed in a zigzag manner.

The buckle head portion 3 is in the form of a flat sheet, and is provided with a snap hole 30 extending through the front side surface 31 and the rear side surface 32 thereof, and the buckle hole 30 extends left and right into a strip shape, and the upper and lower sides thereof The side and left and right side apertures are gradually tapered from the front to the rear.

The strap portion 4 is formed in a flat long strip shape from the bottom side of the snap head portion 3 downward.

As shown in FIGS. 2, 3, and 5, the side tooth portions 5 extend vertically upward and downward along the sleeve portion 4, and each side tooth portion 5 has a plurality of upper and lower teeth arranged in sequence. The side side engaging teeth 51 of the side of the band portion 4, and the side side engaging teeth 51 respectively have a guiding bevel 511 extending obliquely from top to bottom and outward, and a downward blocking edge 512.

The rear side tooth portion 6 also extends upwardly and downwardly along the sleeve band portion 4, and includes a plurality of left and right teeth extending from the left and right sides of the sleeve band portion 4 behind the rear side surface 32. The rear side latch 61 also has a guiding bevel 611 extending obliquely from top to bottom and outwardly, and a downwardly facing stop edge 612.
