Embodiment 1
[0037] Embodiment 1. When performing vessel end-to-end anastomosis reconstruction, as shown in FIG. 9 , firstly, according to the general principle of vessel anastomosis, two sections of blood vessels (38) are trimmed to match the size of the anastomotic edge. According to the outer diameter of the anastomotic edge of the two vessels, select a pair of cylindrical vessel eversion adapters (1) of appropriate size. For example, if the outer diameter of the anastomotic edge is 2 mm, choose a cylindrical vessel with an outer diameter of 2.2 mm in the small group. Turn out the coupler (1). Open the two half-rings (6) of a pair of cylindrical blood vessel valgus abutment device (1) and put them into the stump of a blood vessel (38) to be anastomosed, straighten out the direction of the blood vessel (38), and close the two half rings Make to embrace the blood vessel (38) segment to be anastomosed. Hold a pair of handles (5) in one hand, clamp the edge of the broken end of the blood v...
Embodiment 2
[0038] Embodiment 2. When carrying out end-to-side anastomotic reconstruction of blood vessels, as shown in Figure 11, select a pair of ring-shaped vessel eversion abutment devices (1) of suitable size according to the external dimensions of the anastomotic edges of two sections of blood vessels, for example, If the outer diameter of the vascular anastomotic edge is 2 mm, a pair of circular vessel eversion abutment devices (1) with an outer diameter of 2.2 mm in the small group are selected. The operation process is the same as that of the cylindrical valgus valgus coupler (1). Note that the two pairs of 4 handles (5) held by the hand must first be fitted with each other as shown in the D-D section in Figure 11. Select the toothed U-shaped closing clip (3) to clip and close the edge of the everted vessel (39). The clamping edge distance requires the same standard as that of the cylindrical vessel eversion coupler (1). The error correction operation is the same as the error co...
Embodiment 3
[0039] Embodiment 3. When carrying out blood vessel repairing and forming, as shown in Figure 13, earlier measure blood vessel (38) wound internal diameter with measuring tool, patch (40) is trimmed into the elongate equiangular octagon patch slightly wider than blood vessel wound. slices (40). The major axis of the elongated equiangular octagon patch (40) is slightly longer than the inner diameter of the major axis of the blood vessel wound. According to the inner diameter of the blood vessel wound, select a pair of frame-shaped vessel eversion coupler (1) of suitable size. 1). Hold the stainless steel wing (10) in hand and slide left and right along the round rod (12), so that the distance between the two halves of the frame-shaped vascular valgus coupler (1) is slightly larger than the inner diameter of the long axis of the blood vessel wound, hold the stainless steel wing (10) in one hand, Use the other hand to clamp the edge of the broken end of the blood vessel with va...
