There are significant differences between plastic microvessels and human microvessels, making it difficult to meet training requirements. In the improved models, blood vessels in avian embryos are used as microvascular training models. Since the sampling length of blood vessels in avian embryos is not fixed, the existing fixed clamping mechanism for clamping plastic microvessels cannot be used to fix blood vessels in avian embryos of different lengths.

[0022] The following further describes the utility model in combination with the embodiments shown in the drawings: Embodiment

[0023] As Figures 1-3 shown, a fixing device for a blood vessel model includes a base 1 and a blood vessel clamp 2. The base 1 includes a cross bar 3 and a long-strip-shaped fixed rod 4. The cross bar 3 is vertically and fixedly arranged at one end of the fixed rod 4. A positioning groove 5 and a plurality of grooves 6 equally spaced along the length direction of the fixed rod 4 are arranged on the fixed rod 4. The distance between adjacent grooves 6 is 0.3 mm. The groove 6 is arranged between the positioning groove 5 and the cross bar 3.

[0024] There are two of the vascular clamps 2 on the fixed rod 4 that can adjust the spacing. The vascular clamp 2 is provided with a first clamping portion 7 for clamping on the fixed rod 4 and a second clamping portion 8 for clamping the blood vessel model. The first clamping portion 7 on one of the vascular clamps 2 is clamped and fixed in the groove 6 on the fixed rod 4, and the first clamping portion 7 on the other vascular clamp 2 is clamped and fixed in the positioning groove 5. The whole of the vascular clamp 2 is made of elastic steel wire. The elastic steel wire is bent and staggered to form the first clamping portion 7 of an annular structure. At both ends of the first clamping portion 7, there are transverse segments 9 located in the same plane. The end of the transverse segment 9 facing away from the first clamping portion 7 is bent upward to form a first pressing segment 10. The upper end of the first pressing segment 10 is bent to form a second pressing segment 11. The two second pressing segments 11 are staggered with each other. At the upper end of the second pressing segment 11, there is a clamping segment 12. The two clamping segments 12 are parallel to each other and cooperate with each other to form the second clamping portion 8.

[0025] All the transverse segments 9 are located in the same plane. The cross bar 3 is parallel to the transverse segments 9, and the lowest point of the cross bar 3, the lowest point of the fixed rod 4, and the lowest point of the transverse segments 9 are located in the same plane.

[0026] In the present utility model, the cross bar 3 and the fixed rod 4 are perpendicularly and fixedly connected, enabling the present utility model to be stably placed on a horizontal plane. The lowest point of the cross bar 3, the lowest point of the fixed rod 4, and the lowest point of the transverse segments 9 are located in the same plane, enabling the cross bar 3, the fixed rod 4, and the transverse segments 9 to be placed on the horizontal plane simultaneously, and capable of maintaining the stability of the vascular clamp 2 clamped on the fixed rod 4.

[0027] The present utility model is provided with two vascular clamps 2. One of the vascular clamps 2 is clamped and fixed at the position of the positioning groove 5, and the other vascular clamp 2 is clamped and fixed at the position of the groove 6. By adjusting the vascular clamp 2 to be clamped in different grooves 6, the spacing between the two vascular clamps 2 can be adjusted, so that the present utility model can clamp microvascular models of different lengths, such as avian embryo blood vessels of different lengths.

[0028] When adjusting the distance between the two vascular clamps 2, the position of the vascular clamp 2 clamped and fixed at the position of the positioning groove 5 does not change. The user squeezes the two first pressing segments 10 near the lower end position in the other vascular clamp 2 with two fingers, and the inner diameter of the first clamping portion 7 of the annular structure can be made larger, enabling the first clamping portion 7 to move outside the fixed rod 4 to other groove 6 positions. When the two fingers are released, the first clamping portion 7 can be clamped and fixed in the groove 6 under the elastic action of the vascular clamp 2 itself. At this time, the adjustment of the position of the vascular clamp 2 can be completed, which is very convenient. When it is necessary to clamp the microvascular model, the user presses the two second pressing segments 11 in the vascular clamp 2 downward with two fingers, and the two clamping segments 12 can be separated. The microvascular model is placed between the two clamping segments 12. When the two fingers are released, under the elastic action of the vascular clamp 2, the microvascular model can be clamped, which is very convenient.
