[0054] In actual use, the first part and the second part are connected and form a first angle. The second part is penetrated by a capture tube, and the first part forms a first angle with the axial direction of the capture tube. By moving the capture tube along the extension direction of the blood vessel, foreign matter in the blood vessel can enter the area surrounded by the first part. By moving the second part relative to the capture tube along the axial direction of the capture tube, the area of ​​the surrounding area of ​​the first part can be adjusted, thereby achieving the capture of foreign matter in the blood vessel and further achieving the removal of foreign matter in the blood vessel.

[0055] Therefore, how to prepare the capture trap of the capture device becomes a technical problem that needs to be solved urgently.

[0056] In order to solve the above technical problems, the embodiment of the present disclosure provides a preparation tool for a capture trap, wherein the main body has a first end face and a first side face, the first end face is provided with a first receiving groove, the shape of the first receiving groove is adapted to the target shape of the first part of the capture trap, and the first part of the capture trap is placed in the first receiving groove, so that the shape of the first part can be adjusted to be consistent with the shape of the first receiving groove; the first end face is provided with a second receiving groove, the shape of the second receiving groove is adapted to the target shape of the second part of the capture trap, and the second part of the capture trap is placed in the second receiving groove, so that the shape of the second part can be adjusted to be consistent with the shape of the second receiving groove; a first angle is formed between the first end face and the first side face, the first angle is adapted to the target angle between the first part and the second part of the capture trap, the opening of the first receiving groove is blocked by the first fixing part, and the opening of the second receiving groove is blocked by the second fixing part, so that the angle between the first part placed in the first receiving groove and the second part placed in the second receiving groove can be adjusted to the target angle; by using the above preparation tool, the shape of the capture trap can be adjusted to the target shape, so that the capture trap can be prepared.

[0057] In order to make the above-mentioned objects, features and beneficial effects of the present disclosure more obvious and easy to understand, the specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0058] Combined with reference Figures 1 to 3 ,in, Figure 1 is an exploded schematic diagram of a first capture snare preparation tool in an embodiment of the present disclosure; Figure 2 is an exploded schematic diagram of a second capture snare preparation tooling according to an embodiment of the present disclosure; Figure 3 It is an exploded schematic diagram of the third capture snare preparation tool in the embodiment of the present disclosure.

[0059] Continue to combine references Figures 1 to 3 The capture snare preparation tool may include: a main body 100 , a first fixing part 210 and a second fixing part 220 .

[0060] Specifically, through the cooperation between the main body 100 and the first fixing part 210 and the second fixing part 220, the shape of the capture snare can be adjusted to a target shape, thereby realizing the preparation of the capture snare.

[0061] The main body 100 has a first end face A1 and a first side face A2, wherein a first receiving groove B1 is opened on the first end face A1, and the shape of the first receiving groove B1 is adapted to the target shape of the first part of the capture trap, and a second receiving groove B2 is opened on the first side face A2, and the shape of the second receiving groove B2 is adapted to the target shape of the second part of the capture trap, and the second receiving groove B2 is connected to the first receiving groove B1.

[0062] Specifically, by placing the first part of the capture trap in the first receiving groove B1, the shape of the first part can be adjusted to be consistent with the shape of the first receiving groove B1; by placing the second part of the capture trap in the second receiving groove B2, the shape of the second part can be adjusted to be consistent with the shape of the second receiving groove B2.

[0063] Among them, the first fixing portion 210 is fixed on the first end surface A1, and is used to block the opening of the first accommodating groove B1, and the opening is opposite to the bottom surface of the first accommodating groove B1. The second fixing portion 220 is fixed on the first end surface A1, and is used to block the opening of the second accommodating groove B2, and the opening is opposite to the bottom surface of the second accommodating groove B2. A first angle is formed between the first end surface A1 and the first side surface A2, and the first angle is adapted to the target angle between the first part and the second part of the capture trap.

[0064] Specifically, the first part placed in the first accommodating groove B1 is limited by the main body 100 and the first fixing part 210, and the second part placed in the second accommodating groove B2 is limited by the main body 100 and the second fixing part 220, so that the angle between the first part in the first accommodating groove B1 and the second part placed in the second accommodating groove B2 is adapted to the first angle between the first end face A1 and the first side face A2.

[0065] In some embodiments, the first angle may range from 60 degrees to 120 degrees. For example, the first angle may be 90 degrees.

[0066] In some embodiments, the first accommodation groove B1 may be an annular groove. For example, the first accommodation groove B1 may be a circular groove. For example, the first accommodation groove B1 may be an elliptical groove.

[0067] In some embodiments, the bottom surface of the first receiving groove B1 and the bottom surface of the second receiving groove B2 may be in an arc transition at the connecting position.

[0068] Specifically, this allows the first part and the second part to transition in an arc at the connection position, thereby avoiding creases at the connection position between the first part and the second part, thereby reducing the probability of the capture snare breaking at the connection position due to the creases at the connection position.

[0069] It should be pointed out that the capture trap is a structure formed by a metal wire. When preparing the capture trap, one end of the metal wire is located in the second receiving groove B2, and the other end is wound around the first receiving groove B1 and then returned to the second receiving groove B2, wherein the part of the metal wire located in the first receiving groove B1 is the first part of the capture trap, and the part located in the second receiving groove B2 is the second part.

[0070] In some embodiments, the width of the first receiving groove B1 is smaller than the width of the second receiving groove B2.

[0071] Specifically, the first part of the capture trap in the first receiving groove B1 is a single metal wire, and the second part of the capture trap in the second receiving groove B2 is two metal wires. Compared with the groove width of the first receiving groove B1 being consistent with the groove width of the second receiving groove B2, setting the groove width of the first receiving groove B1 to be smaller than the groove width of the second receiving groove B2 can reduce the gap between the first part placed in the first receiving groove B1 and the first receiving groove B1, thereby enhancing the limiting effect of the first receiving groove B1 and the first fixing portion 210 on the first part, and further reducing the deviation between the shape of the first part and the target shape.

[0072] In some embodiments, the first receiving groove B1 has a protruding portion B11, the protruding portion B11 of the first receiving groove B1 is V-shaped, and the tip of the V-shape protrudes in a direction away from the first axis, wherein the first axis is the central axis of the area surrounded by the first receiving groove B1.

[0073] Specifically, the first part of the capture snare is adapted to the shape of the first receiving groove B1, so that the formed first part also has a protruding part corresponding to the protruding part B11 of the first receiving groove B1, wherein the protruding part of the first part is used for the snare to cooperate with the foreign object barb to increase the chance of capturing foreign objects.

[0074] In some embodiments, the V-shape of the protruding portion of the first receiving groove B1 is closer to a U-shape at the tip, and the side wall of the V-shape of the protruding portion of the first receiving groove B1 at the tip may be an arc transition.

[0075] Specifically, the protruding portion of the first part conflicts with the side wall of the first accommodating groove B1, and the side wall of the V-shaped protruding portion B11 of the first accommodating groove B1 is an arc transition at the tip, so that the protruding portion of the first part can make an arc transition at the tip, thereby avoiding the protruding portion of the first part from generating creases at the tip, thereby reducing the probability of the capture trap breaking at the tip due to the creases at the tip.

[0076] In some embodiments, the side wall of the protruding portion B11 of the first receiving groove B1 and the side wall of other portions of the first receiving groove B1 may transition in an arc shape at the connection position.

[0077] Specifically, the protruding portion of the first part interferes with the side wall of the first accommodating groove B1, and the side wall of the protruding portion B11 of the first accommodating groove B1 and the side wall of other parts of the first accommodating groove B1 can make an arc transition at the connecting position. In this way, the protruding portion of the first part can make an arc transition at the connecting position, thereby avoiding the generation of creases on the protruding portion of the first part at the connecting position, thereby reducing the probability of the capture trap breaking at the connecting position due to the creases at the connecting position.
