[0016] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0017] refer to Figure 1-Figure 5 The utility model provides a balloon catheter installation auxiliary stretching tool, including a base plate 1, a slideway 11 is provided on the base plate 1, a fixed block 2 is fixedly provided at one end of the slideway 11, a sliding block 3 is slidably connected on the slideway 11, a first chuck 6 is provided on the side of the fixed block 2 close to the sliding block 3, a first chuck cap 7 is provided on the first chuck 6, a second chuck 8 is provided on the side of the sliding block 3 close to the fixed block 2, a second chuck cap 9 is provided on the second chuck 8, and a limiting structure is provided on the sliding block 3.

[0018] When in use, use the first clamp 6 on the fixed block 2 to clamp the catheter 8 and the balloon 10, and use the second clamp 14 on the sliding block 3 to clamp the balloon 10, so that the sliding block 3 slides to the right, thereby stretching the balloon 10. The position of the sliding block 3 is fixed by the limiting structure, and the developing ring 9 on the balloon 10 is moved to the specified position. After completion, the catheter 8 is removed and the next step is carried out.

[0019] Preferably, the ends of the first chuck 6 and the second chuck 8 that are close to each other are both set as a cross-cut structure, and the first chuck cap 7 and the second chuck cap 9 are provided with gradually shrinking grooves inside, the first chuck cap 7 is sleeved on the first chuck 6, and the second chuck cap 9 is sleeved on the second chuck 8, and the ends of the first chuck cap 7 and the second chuck cap 9 that are close to each other are provided with a hole.

[0020] When the first chuck 6 is ready to clamp the catheter 8 and the balloon 10, pull the first chuck cap 7 out a certain distance to loosen the cross cut, pass one end of the catheter and the balloon through the hole on the first chuck cap 7, and insert into the cross cut of the first chuck 6, then push the first chuck cap 7 to make the cross cut clamp the catheter and the balloon, and then install the second chuck 8. During installation, adjust the tightness between the second chuck cap 9 and the second chuck 8 so that the second chuck 8 can clamp the balloon without clamping the catheter 8, and then stretching can be performed.

[0021] In order to facilitate the connection between the first clamp 6 and the second clamp 8, as a preferred technical solution, a connecting plate 12 with an L-shaped cross-section is provided at the upper end of the side where the fixed block 2 and the sliding block 3 are close to each other, and the first clamp 6 and the second clamp 8 are both arranged on the corresponding connecting plate 12.

[0022] As a specific implementation method of the limiting structure, the limiting structure includes a limiting pin 4, a limiting connecting plate 13 is horizontally arranged on the sliding block 3, the limiting pin 4 is movably connected to the limiting connecting plate 13, and a long hole 14 is arranged on the bottom plate 1, and the long hole 14 is arranged on the movement trajectory of the limiting pin 4.

[0023] During stretching, the limit pin 4 slides with the sliding block 3 and slides to a suitable position according to the product size. The limit pin 4 is used to fix the position of the sliding block 3 at the fixed position of the long hole 14, and then the developing ring 9 is moved.

[0024] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of the present invention.
