Description

Technical Field

[0001] This utility model relates to the field of vascular stent technology, and in particular to a pressure-adjustable grip support system. Background Technology

[0002] Currently, vascular stents refer to the insertion of an internal stent into the diseased segment of the blood vessel after balloon dilation and shaping of the lumen. This aims to support the narrowed or occluded segment, reduce vascular elastic recoil and remodeling, and maintain unobstructed blood flow. Some stents also have the function of preventing restenosis. They are mainly divided into coronary stents, cerebral stents, renal artery stents, and aortic stents.

[0003] Current vascular stents require a gripping operation during production. This operation involves using specialized gripping equipment to compress a pre-cut stent with a larger diameter onto the surface of a stent delivery balloon. During this process, the stent delivery balloon is already folded, and its outer diameter differs significantly from the inner diameter of the stent to be gripped. Conventional gripping operations lack support during stent compression deformation, resulting in free deformation that can easily lead to distortion and twisting, affecting product quality and production efficiency. Pre-compressing the stent before final gripping onto the balloon surface significantly improves gripping quality by reducing the difference between the stent's inner diameter and the balloon's outer diameter. Therefore, designing an adjustable gripping support system is essential. Utility Model Content

[0004] To address the technical problem that vascular stents are prone to deformation due to lack of internal support when gripped, this invention provides a pressure-adjustable gripping support system.

[0005] This utility model is achieved by the following technical solution: a pressure-adjustable grip support system, including a bracket, a support component that can support the bracket being gripped, an activation component that can drive the support component to support the bracket on one side, a compression sleeve for gripping force is sleeved on the outside of the bracket, and the support component includes an air bladder disposed inside the bracket and a first air tube connected to one side of the air bladder.

[0006] With the above technical solution, when the bracket is gripped, the activation component will enable the support component to support the inside of the bracket. In this way, when the bracket is gripped, there will be internal support force to prevent the bracket from being deformed by gripping. This setting can both assist in gripping the bracket and prevent the bracket from being deformed by gripping.

[0007] As a further improvement to the above solution, the starting component includes a second air pipe disposed on one side of the first air pipe and an air pump fixedly connected to one end of the second air pipe.

[0008] With the above technical solution, when the air pump is turned on, the airbag will be inflated through the first air pipe and the second air pipe.

[0009] As a further improvement to the above solution, two rubber rings are fixedly sleeved on the circumferential surface of the airbag, and the bracket is located between the two rubber rings.

[0010] The rubber ring can prevent the bracket from shifting when gripped using the above technical solution.

[0011] As a further improvement to the above solution, a three-way valve is provided between the first air pipe and the second air pipe, and both the first air pipe and the second air pipe are fixedly connected to the three-way valve.

[0012] With the above technical solution, the first and second air pipes are connected by a three-way valve, allowing gas to flow between them.

[0013] As a further improvement to the above solution, a third air pipe is fixedly connected to one side of the three-way valve, and a smart pressure valve is fixedly connected to one end of the third air pipe.

[0014] Through the above technical solution, the intelligent pressure valve can continuously discharge gas within a limited pressure range.

[0015] As a further improvement to the above solution, the airbag is arranged in a cylindrical shape.

[0016] The above technical solution allows cylindrical airbags to be more easily placed inside the support structure.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] This invention, by setting up a support component and an activation component, allows the support component to support the inside of the bracket when the bracket is being gripped. This provides internal support when the bracket is gripped, preventing deformation of the bracket during gripping. This design both assists in gripping the bracket and prevents deformation of the bracket during gripping. Attached Figure Description

[0024] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] Please combine Figures 1-3 This embodiment of a pressure-adjustable gripping support system includes a bracket 1. The bracket 1 is provided with a support component that can support the bracket 1 during gripping. One side of the support component is provided with an activation component that can drive the support component to support the bracket 1. The bracket 1 is covered with a compression sleeve 4 for gripping force. The support component includes an air bladder 201 disposed inside the bracket 1 and a first air tube 202 connected to one side of the air bladder 201. When the bracket 1 is gripped, the activation component will cause the support component to support the inside of the bracket 1. In this way, when the bracket 1 is gripped, there will be a supporting force inside the bracket, preventing deformation of the bracket during gripping.

[0026] Combination Figure 1 The activation component includes a second air tube 301 disposed on one side of the first air tube 202 and an air pump 302 fixedly connected to one end of the second air tube 301. When the air pump 302 is turned on, it will inflate the airbag 201 through the first air tube 202 and the second air tube 301.

[0027] Combination Figure 1 Two rubber rings 5 ​​are fixedly fitted on the circumferential surface of the airbag 201, and the bracket 1 is located between the two rubber rings 5. The airbag 201 is cylindrical. A three-way valve 6 is provided between the first air tube 202 and the second air tube 301. Both the first air tube 202 and the second air tube 301 are fixedly connected to the three-way valve 6. The cylindrical airbag 201 can be more easily placed inside the bracket 1.

[0028] Combination Figure 1 A third air pipe 7 is fixedly connected to one side of the three-way valve 6, and a smart pressure valve 8 is fixedly connected to one end of the third air pipe 7. The smart pressure valve 8 also has an automatic pressure relief valve with adjustable pressure. The smart pressure valve 8 can continuously discharge gas within a limited pressure range.

[0029] The implementation principle of a pressure-adjustable grip support system in this application embodiment is as follows: the deflated airbag 201 is placed inside the bracket 1, and then the air pump 302 is turned on to inject the set gas into the airbag 201, so that the airbag 201 will inflate and give the bracket 1 a certain internal support force of about 1 atm-10 atm.

[0030] Next, the three-way valve 6 rotates to connect to the intelligent pressure valve 8 and disconnects from the air pump 302. The intelligent pressure valve 8 also has an automatic pressure relief valve with adjustable pressure. The intelligent pressure valve 8 is pre-set with the required pressure parameters so that when the pressure is too high, it will automatically discharge the gas inside the airbag 201, keeping the pressure at the set value.

[0031] After all settings are complete, the compression sleeve 4 will compress the bracket 1. Due to the support of the airbag 201, the bracket 1 will not deform due to excessive compression. The airbag 201 will also gradually release gas in conjunction with the intelligent pressure valve 8 due to pressure issues, which facilitates the compression of the bracket 1. Because of the presence of the airbag 201, there is good internal support, which avoids abnormal deformation of the bracket 1, so that the compression deformation of the bracket 1 is carried out under controlled internal support.

[0032] As the compression sleeve 4 continues to compress, the volume of the airbag 201 decreases and the pressure increases. When the pressure increases to the set pressure of the intelligent pressure valve 8, the intelligent pressure valve 8 automatically opens to release the pressure; this ensures that the set pressure is maintained inside the airbag 201.

[0033] This design not only helps to grip the bracket 1, but also prevents the bracket 1 from being deformed by gripping.

[0034] The above embodiments are merely preferred embodiments of this utility model and should not be construed as limiting the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
