Description

Technical Field

[0001] This utility model belongs to the field of vascular stent technology, specifically a vascular stent for medical intervention. Background Technology

[0002] Vascular stents are inserted into the diseased segment of a blood vessel after balloon dilation and shaping. This supports the narrowed or occluded segment, reduces elastic recoil and remodeling, and maintains unobstructed blood flow. Some stents also have the function of preventing restenosis. Because vascular stents are quite sophisticated and expensive, their safe storage is extremely important. Damage to stents during transportation or storage can have serious consequences. The economic losses are one aspect, but if the patient's treatment is delayed, the consequences are incalculable.

[0003] Meanwhile, the patent specification with publication number CN 208552126 U discloses a vascular stent, including: a balloon and a stent mesh surrounding the balloon; a central lumen penetrating the balloon; and a groove penetrating the vascular stent, the groove having a slot opposite to the stent mesh, and a guide wire passing through the groove to form a peripheral lumen of the vascular stent.

[0004] However, during the implementation of the relevant technology, the following problems were found with the above-mentioned vascular stent: the stent is small and of low quality, resulting in insufficient overall strength and making it difficult to preserve. If care is not taken during daily storage and transportation, the stent may be damaged. Damage to the vascular stent will cause some economic losses, but more importantly, the damaged stent will cause incalculable harm to the patient's treatment, delaying the patient's treatment, and the consequences are difficult to estimate.

[0005] Therefore, a vascular stent for medical intervention is proposed to address the above problems. Utility Model Content

[0006] To address the problems mentioned in the background art, this utility model provides a vascular stent for medical intervention, which has the advantage of protecting the vascular stent. This device places the stent inside and forms a protective structure for the stent through multiple structures, reducing the damage it suffers during daily storage and transportation, thereby ensuring the use value of the stent. This not only reduces economic losses but also provides protection for the patient's health, avoiding situations where the stent's use causes damage and delays the patient's condition.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a vascular stent for medical intervention, comprising a vascular stent body, an inner support cylinder slidably disposed inside the vascular stent body, a protective cylinder slidably disposed outside the vascular stent body, end caps fitted at both ends of the protective cylinder, a clamping shell interference-connected to the outside of the protective cylinder, an upper cover slidably disposed on the bottom surface of the clamping shell, and a locking point fixedly disposed on the bottom surface of the clamping shell.

[0008] Preferably, the vascular stent body is made of a covered stent or a biomaterial stent, and a thin drug film is disposed on the surface of the vascular stent body.

[0009] Preferably, a self-locking switch is interference-connected to the outside of the locking point, and a bottom shell is fixedly connected to the outside of the self-locking switch.

[0010] Preferably, a balance plate is fixedly provided on the bottom surface of the clamping shell, and a spring is fixedly provided on the bottom surface of the balance plate.

[0011] Preferably, a top cone is fixedly provided on the top surface of the bottom shell, and a disinfectant cotton is provided through the outer side of the top cone, and the disinfectant cotton is in contact with the surface of the top cover.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 4 As shown, this utility model provides a vascular stent for medical intervention, including a vascular stent body 15. An inner support cylinder 16 is slidably disposed inside the vascular stent body 15, and a protective cylinder 14 is slidably disposed outside the vascular stent body 15. End caps 13 are fitted at both ends of the protective cylinder 14. A clamping shell 8 is interference-connected to the outside of the protective cylinder 14. A top cover 7 is slidably disposed on the bottom surface of the clamping shell 8, and locking points 12 are fixedly disposed on the bottom surface of the clamping shell 8. The inner support cylinder 16 provides support inside the vascular stent body 15, thereby preventing deformation. At the same time, the protective cylinder 14 on the outside of the vascular stent body 15 protects the vascular stent body 15 from external damage. Finally, the protective cylinder 14 is placed inside the clamping shell 8, and then the top cover 7 is closed to apply another layer of protection. At the same time, a sterilizing agent is disposed inside the clamping shell 8 to prevent bacterial growth. Multiple protections ensure safety.

[0023] Specifically, the material of the vascular stent body 15 is a covered stent or a biomaterial stent. A thin drug film is provided on the surface of the vascular stent body 15. Since metal stents will be rejected by the human body, the contact area will cause certain trauma. Therefore, these materials that are less harmful to the human body or even absorbable are selected. The drug film can reduce the damage of the stent to the human body.

[0024] Furthermore, a self-locking switch 11 is interference-connected to the outside of the locking point 12. The bottom shell 1 is fixedly connected to the outside of the self-locking switch 11. When the top cover 7 is pressed, the self-locking switch 11 will release the locking point 12. While locking the locking point 12, the self-locking switch 11 also fixes the clamping shell 8, thereby maintaining the stability of the clamping shell 8.

[0025] Furthermore, a balance plate 9 is fixedly installed on the bottom surface of the clamping shell 8, and a spring 10 is fixedly installed on the bottom surface of the balance plate 9. The balance plate 9 is used to balance the clamping shell 8, and the spring 10 is used to pop out the clamping shell 8 so that it is convenient for medical staff to take it.

[0026] It is worth noting that a top cone 6 is fixedly installed on the top surface of the bottom shell 1, and a disinfectant cotton 5 is installed through the outer side of the top cone 6. The disinfectant cotton 5 is attached to the surface of the top cover 7. The function of the disinfectant cotton 5 is to cover the top cover 7 and avoid direct sunlight.

[0027] It is worth noting that a protective cover 2 is fitted onto the top surface of the bottom shell 1, and a storage ring 4 is fixedly installed inside the protective cover 2. By placing the protective cover 2 on top of the bottom shell 1, the last layer of protection is completed, and the bracket can be stored.

[0028] It is worth mentioning that the protective cover 2 has an outer ring 3 fixedly installed inside, and an open film is fixedly installed at one end of the outer ring 3. The holding ring 4 is fixedly installed inside the outer ring 3. When the protective cover 2 is placed on top of the bottom shell 1, the top cone 6 will break through the film, and the medicine inside the holding ring 4 will emit an odor to repel ants, mosquitoes and other insects, thereby protecting the bracket.

[0029] The self-locking switch 12 is existing technology and will not be described in detail. Additionally, this utility model also includes a power supply, controller, and switches, which are not the main technical points of this patent and will not be described in detail. The "front, back, left, and right" views of this device are... Figure 1 The direction shown in the diagram is the reference.

[0030] Working principle and process:

[0031] When using the vascular stent body 15, first, open the protective cover 2 on the top of the bottom shell 1. Inside the protective cover 2, there is an outer ring 3, and the surface of the outer ring 3 is covered with an open film. When the protective cover 2 is placed on top of the bottom shell 1, the top cone 6 will puncture the film, and the medication in the holding ring 4 will release its scent, thereby repelling ants, mosquitoes, and other insects and preventing them from approaching. After removing the protective cover 2, lift the sterilization cotton 5, and the top cover 7 will be exposed. Press the top cover 7, and the self-locking switch 11 will release the locking point 12. At this time, the top cover 7 and the clamping shell 8 can be removed. The balance plate 9 on the bottom surface of the clamping shell 8 is used to balance the clamp. The function of the fixed shell 8 and spring 10 is to pop out the fixed shell 8 to facilitate the medical staff to take it out. Then, open the top cover 7, take out the protective tube 14, remove the left and right end caps 13, pull out the inner support tube 16, and finally take out the vascular stent body 15 from the outside of the inner support tube 16. This device places the stent inside and protects the stent through multiple structures, reducing the damage it suffers during daily storage and transportation, thereby ensuring the use value of the stent. This not only reduces economic losses, but also provides protection for the patient's health and avoids the situation where the patient's condition is delayed due to damage caused by the use of the stent.
