The guiding mechanism 1 comprises a grid plate 11, a vibrating mechanism and a second extruding mechanism 13, specifically, a guiding groove 111 for placing the blood vessel support 100 is arranged on the grid plate 11, the guiding groove 111 inclines to a second set angle relative to the conveying mechanism, a guiding pipe 12 is connected to the bottom of the guiding groove 111, the diameter of the guiding pipe 12 is matched with the outer diameter of the blood vessel support 100, the direction of the blood vessel support 100 conveyed to the conveying mechanism is stable, and the guiding groove is orderly arranged, the vibrating mechanism is connected with the grid plate 11, the vibrating mechanism enables the blood vessel support 100 to enter the guiding pipe 12 from the guiding groove 111 through vibration, the vibrating mechanism can comprise a hollow cup or a motor and the like, which are the prior art and are not repeated.

Optionally, the transmission mechanism comprises a chain transmission assembly 21, and a clamping assembly 22 arranged on the chain transmission assembly 21, wherein the clamping assembly 22 is used for clamping the first end of the blood vessel stent 100 and can pull the blood vessel stent 100 to move under the driving of the chain transmission assembly 21. The introduction mechanism 1 can guide the blood vessel stent 100 to be treated to the holding member 22 and is held by the holding member 22.

In this embodiment, the reaction container 3 is a flat glass box, and can be supported and fixed by the support, and a chamber 31 penetrating through the glass box and having two open ends is disposed on the glass box, as shown in fig. 1, the chamber 31 has an a end and a B end disposed oppositely, the clamping mechanism 4 is disposed at the a end, the clamping mechanism 4 further has a second clamping state, when the clamping mechanism 4 is in the second clamping state, the clamping mechanism 4 clamps the second end of the blood vessel support 100 and provides a second clamping force to the blood vessel support 100, and the second clamping force is greater than the traction force. The chain transmission assembly 21 comprises a chain 211 and a chain wheel 212, the clamping assembly 22 is arranged on the chain 211, an elastic plate 6 is arranged on the chain 211, the elastic plate 6 is located at the downstream of the clamping assembly 22, the chain 211 can drive the elastic plate 6 and the clamping assembly 22 to enter the cavity 31 from the end A in sequence, when the elastic plate 6 is located at the end B, the end B is blocked by the elastic plate 6, and the clamping mechanism 4 is in a second clamping state and blocks the end A. It is understood that the cross-sectional shape and size of the elastic plate 6 are adapted to the cross-sectional shape and size of the cavity 31, so that the elastic plate 6 can close the opening 2222 at the B end of the cavity 31, and the material of the elastic plate 6 is preferably silicon rubber, but may also be rubber.

In this embodiment, when the elastic plate 6 moves to the end B, the clamping mechanism 4 is switched from the first clamping state to the second clamping state, at this time, the intravascular stent 100 is located in the chamber 31 except for the end clamped by the clamping mechanism 4, and the elastic plate 6 and the clamping mechanism 4 cooperate to close the end a and the end B of the chamber 31, so as to facilitate the subsequent injection of the reagent into the reaction vessel 3. Specifically, the top of the reaction vessel 3 is provided with an injection hole for injecting a reagent, the injection hole communicates with the chamber 31, and the reagent can be injected into the chamber 31 through the injection hole. In addition, since the blood vessel support 100 can be tensioned and suspended in the cavity 31 of the reaction vessel 3, only the cross-sectional dimension of the cavity 31 is slightly larger than the outer diameter of the blood vessel support 100, so that the flat reaction vessel 3 can be adopted in the embodiment, and thus the reagent consumption can be reduced. After the reagent is solidified, the clamping mechanism 4 can be switched from the second clamping state to the clamping force-free state, and at this time, the clamping mechanism 4 is separated from the blood vessel support 100 without any force therebetween, so that the chain 211 pulls the treated blood vessel support 100 out of the chamber 31 through the clamping assembly 22.

Specifically, referring to fig. 3 and 4, in the present embodiment, the transmission mechanism includes two chain transmission assemblies 21, the two chain transmission assemblies 21 are arranged side by side and spaced apart, each chain transmission assembly 21 includes two chain wheels 212 and a chain 211 tensioned on the two chain wheels 212, wherein one chain wheel 212 can be in transmission connection with a motor, and the motor can drive the chain 211 to rotate.

The chain links comprise groove joints and connecting joints 2111, and in two adjacent chain links, the groove joint of one chain link is pivoted with the connecting joint 2111 of the other chain link. The slot section comprises two connecting pieces 2112 which are arranged side by side and at intervals, the two connecting pieces 2112 are pivoted to two opposite sides of the connecting section 2111 through a rotating shaft 2113, so that a tooth slot is formed between the two connecting pieces 2112, and the chain wheel 212 can be meshed with the tooth slot.

After the blood vessel stent 100 is processed, the chain 211 drives the elastic plate 6 and the clamping assembly 22 to sequentially come out of the chamber 31, at this time, the opening 2222 of the elastic body 222 is opened, the elastic body 222 loosens the processed blood vessel stent 100, and at this time, the blood vessel stent 100 enters between two rollers of the first extrusion mechanism and is conveyed to the receiving plate 5 by the first extrusion mechanism.
