Description

Technical Field

[0001] The utility model relates to the field of medical device equipment, and particularly relates to a shaping device for a contrast catheter. Background Art

[0002] The contrast catheter is a key instrument for percutaneous angiography, which is applicable to the interventional diagnosis and treatment of vascular diseases. Its main function is to provide a channel for the contrast agent to smoothly enter the blood vessel to produce a contrast effect, display the scope, location and degree of arterial stenotic lesions, and is an important means for clear diagnosis. It should have appropriate hardness, elasticity, flexibility and torsional controllability; it should have good X-ray transparency; good shape memory, smooth tube wall and high contrast performance.

[0003] At present, most of the shaping of the head end of the common contrast catheter is a two-dimensional structure, and the contrast effect is poor. In order to obtain a better contrast effect, a three-dimensional structure contrast catheter needs to be used. In the prior art, the three-dimensional structure shaping of the contrast catheter is mainly realized by steam shaping. However, for some relatively large tube bodies, it takes a long time to use steam shaping, and the consistency is poor.

[0004] The patent with the publication number of "CN206465451U" discloses "a contrast catheter forming machine", which includes a heating mechanism and a cooling mechanism connected to the heating mechanism through a connecting rod; the heating mechanism includes a heating base, a heating pot and a heating circuit. The heating base is hollow and has an opening at the top. A heating plate is provided at the bottom inside the heating base. The heating pot has a heating cavity and an opening at the top. The heating circuit includes a wire connected to the heating plate, a plug provided at the end of the wire, and a switch provided on the outer wall of the heating base for controlling the on-off of the heating circuit; the cooling mechanism includes a cooling base and a cooling pot. The cooling base is hollow and has an opening at the top. The cooling pot has a cooling cavity and an opening at the top. However, the heating pot and the cooling pot of this solution are separately arranged, and the contrast catheter needs to be moved during the forming process, resulting in inconvenient use.

[0005] Therefore, our company proposes a shaping device for a contrast catheter. Summary of the Invention

[0006] The purpose of the utility model is to provide a shaping device for a contrast catheter, which can realize the rapid shaping of the contrast catheter.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

A space for accommodating the contrast catheter is formed between the first shaping part and the second shaping part. At least one of the first shaping part and the second shaping part can reciprocally move along the fixed bottom plate.

[0009] Preferably, the first shaping part includes a first heating plate, a first shaping mold in contact with the contrast catheter is arranged on one side of the first heating plate, and a first heat insulation plate is arranged on the other side of the first heating plate;

[0011] Preferably, a second heat insulation plate is arranged at the lower part of the first shaping part, and the second heat insulation plate is arranged on the fixed bottom plate;

[0012] A fourth heat insulation plate is arranged at the lower part of the second shaping part, and the fourth heat insulation plate is arranged on the movable plate.

[0013] Preferably, a guide rail is arranged on the fixed bottom plate, a guide rail sliding plate is arranged on the guide rail, and the movable plate is arranged on the guide rail sliding plate.

[0014] Preferably, a cooling device is arranged on the fixed bottom plate, and the cooling device has cooling holes for blowing air to the first heating plate and the second heating plate.

[0015] Preferably, both the first shaping mold and the second shaping mold are arc-shaped, and grooves matching the outer edge of the contrast catheter are formed on the surfaces of the first shaping mold and the second shaping mold in contact with the contrast catheter.

[0016] Preferably, a telescopic rod is arranged on the fixed bottom plate, and one end of the telescopic rod is connected to the movable plate.

[0017] Preferably, the telescopic rod is a cylinder.

[0018] The beneficial effects of the present utility model are as follows:

[0019] 1. Through the arrangement of the arc-shaped first shaping part and the second shaping part, the three-dimensional shaping of the head end of the contrast catheter is realized, greatly improving the working efficiency and also improving the consistency of the product.

[0020] 2. By the form of pushing the movable plate by the cylinder, the contrast catheter can be placed and shaped during extrusion, and the shaped contrast catheter can be taken out when separated, reducing the operation pressure of the staff.

A space for accommodating a contrast catheter 7 is formed between the first shaping part 2 and the second shaping part 3. The first shaping part 2 is fixedly arranged, and the second shaping part 3 can reciprocate along the fixed bottom plate 1. When it approaches and contacts the first shaping part 2, it realizes the shaping of the contrast catheter, and when it moves away from the first shaping part 2, the shaped contrast catheter can be taken out.

[0029] As Figure 3 shown, the first shaping part 2 includes a first heating plate 22. A first shaping mold 21 that contacts the contrast catheter 7 is arranged on one side of the first heating plate 22, and a first heat insulation plate 23 is arranged on the other side of the first heating plate 22;

[0030] The second shaping part 3 includes a second heating plate 32. A second shaping mold 31 that contacts the contrast catheter 7 is arranged on one side of the second heating plate 32, and a third heat insulation plate 33 is arranged on the other side of the second heating plate 32. Both the first shaping mold 21 and the second shaping mold 31 are circular arcs, and grooves matching the outer edge of the contrast catheter 7 are opened on the surfaces that contact the contrast catheter 7 (not shown in the figure. The grooves on the first shaping mold 21 and the second shaping mold 31 are both half grooves. When the first shaping mold 21 and the second shaping mold 31 contact, the two half grooves are combined into one, and its inner diameter matches or is slightly larger than the outer edge of the contrast catheter 7), so that the contrast catheter 7 can be smoothly placed into the groove for shaping the contrast catheter 7.
