Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a retractable and positionable interventional surgical angiography catheter fixation device. Background Technology

[0002] In interventional procedures, the use of angiography catheters is crucial. Angiography catheters in interventional procedures are medical devices mainly used to perform imaging examinations and treatments inside the body through blood vessels. An interventional angiography catheter is a thin, flexible tube, usually made of medical plastic or other soft materials, which can flexibly pass through the vascular system.

[0003] Interventional angiography catheters mainly consist of an angiography catheter, guidewire, and display screen. Through the cooperation of the catheter and guidewire, they are precisely inserted into the patient's vascular system to perform angiography or treatment. The guidewire is first guided through the blood vessel, serving a positioning and guiding function to ensure the catheter reaches its target location smoothly. Then, the angiography catheter enters the target blood vessel through the guidewire, and contrast agent is injected through the catheter. The contrast agent flows through the blood vessel, displaying information on the display screen, thereby helping doctors diagnose vascular lesions and perform interventional treatment procedures, such as vascular stent implantation and thrombus removal.

[0004] In existing technologies, the current catheter fixation methods for some interventional angiography catheter devices often rely on manual operation, which can easily lead to catheter displacement during the operation, thereby reducing the accuracy of angiography and the safety of the surgery. This can cause the catheter to loosen when a certain external force is applied, which also increases the risk and patient discomfort. Therefore, a telescopic positioning interventional angiography catheter fixation device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a retractable and positionable interventional surgical angiography catheter fixation device, which aims to improve the problem that some existing devices cannot fix their angiography catheters during use.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A retractable and positionable interventional angiography catheter fixation device includes an injection tube and a sliding ring. An angiography catheter one is fixedly connected inside the injection tube, and an angiography catheter two is slidably connected inside the injection tube. A connecting seat is fixedly connected to the bottom of the sliding ring. A rotation limiting block is rotatably connected inside the connecting seat. A rotating block is rotatably connected inside the rotation limiting block. A heating and temperature control component is fixedly connected inside the rotation limiting block and the adhesive fastening tape. An adhesive fastening tape is fixedly connected to the outside of the rotation limiting block, and an adhesive fastening tape is slidably connected to the outside of the rotating block.

[0009] The heating and temperature control assembly includes two heating blocks. The heating blocks are externally fixedly connected to the rotation limit block and the interior of the rotation block. A temperature-controlling sponge is fixedly connected to the interior of the heating blocks.

[0010] As a further description of the above technical solution:

[0011] The rotating block is rotatably connected inside the connecting seat, and the temperature-controlling sponge is rotatably connected to the heating block inside the connecting seat.

[0012] As a further description of the above technical solution:

[0013] The injection tube is fixedly connected to a connecting cylinder on the outside, and the sliding ring is slidably connected to the outside of the connecting cylinder on the inside.

[0014] As a further description of the above technical solution:

[0015] A rubber pad is fixedly connected inside the connecting cylinder, and a thin film is fixedly connected to the outside of the connecting cylinder.

[0016] As a further description of the above technical solution:

[0017] The sliding ring is externally fixedly connected to a display screen, and the angiography catheter has an internal telescopic component for providing sliding.

[0018] As a further description of the above technical solution:

[0019] The telescopic assembly includes an angiography catheter 2. The angiography catheter 1 has multiple limiting grooves inside. Limiting rubber balls are fixedly connected to the outer sides of the limiting grooves. The outer sides of the two limiting rubber balls are slidably connected inside the multiple limiting grooves.

[0021] The guidewire is slidably connected inside the injection tube, and the guidewire is slidably connected to the outside of the angiography catheter II. The outside of the angiography catheter II is slidably connected to the inside of the angiography catheter I.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the sliding ring slides and the adhesive fastening band is opened, allowing the rotating limit block and the rotating block to rotate. The internal heating block heats the temperature-controlled sponge, making it more comfortable during fixation.

Detailed Implementation

[0032] 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.

[0033] Reference Figure 1 , Figure 3 , Figure 4 This utility model provides an embodiment of a retractable and positionable interventional angiography catheter fixation device, comprising an injection tube 1 and a sliding ring 11. The injection tube 1 is the core channel of the entire device, and its main function is to contain and guide the delivery of contrast agents and other liquids. The injection tube 1 is usually made of medical-grade polymer materials, such as polyvinyl chloride or polyurethane. An angiography catheter 2 is fixedly connected inside the injection tube 1. The angiography catheter 2 serves as one of the main delivery channels for the contrast agent. The angiography catheter 2 is usually made of a soft but strong material to ensure that it can smoothly advance along the direction of the blood vessel when inserted into the blood vessel, while also withstanding a certain pressure without deformation. An angiography catheter 3 is slidably connected inside the injection tube 1. The angiography catheter 3 slides relative to the angiography catheter 2 inside the angiography catheter 2, realizing the retractable function of the catheter and providing a retractable position for interventional surgery. For greater operational flexibility, the position of the contrast agent injection point can be adjusted by extending and retracting the contrast catheter 2 3 within the contrast catheter 1 2. The bottom of the sliding ring 11 is fixedly connected to the connecting seat 5. The sliding ring 11 is a key adjustable component, and its bottom is firmly fixedly connected to the connecting seat 5. The sliding ring 11 is made of engineering plastic with a smooth surface to allow for smooth sliding on the outside of the connecting cylinder 17 and to be fixed at different positions on the patient's arm and leg. The connecting seat 5 is rotatably connected to the rotating limit block 6. The rotating limit block 6 and the connecting seat 5 form a rotatable connection, providing an angle adjustment function for the operation of the device. The rotating limit block 6 is semi-circular or disc-shaped and made of high-strength plastic. It has a precise rotating structure inside to ensure a tight fit with the rotating block 8. The rotating limit block 6 is rotatably connected to the rotating block 8.

[0034] A heating assembly is internally fixedly connected to the rotating limit block 6 and the adhesive fastening band 7. The heating and temperature control assembly includes two heating blocks 9, which are externally fixedly connected to the interior of the rotating limit block 6 and the rotating block 8. A temperature-controlling sponge 10 is internally fixedly connected to the heating block 9. The externally fixedly connected to the rotating limit block 6 is the adhesive fastening band 7, which is used to fix the equipment in a proper position and prevent unnecessary rotation during operation. The adhesive fastening band 7 is made of fabric with many small hooks. The surface of the rotating limit block 6 has a fabric composed of a group of tiny ring structures, which slides on the surface of the rotating limit block 6 for fixation. The externally slidably connected to the rotating block 8 is the adhesive fastening band 7, and the rotating block 8 is rotatably connected to... Inside the connector 5, the temperature-controlled sponge 10 and the heating block 9 are rotatably connected. When current passes through the heating wire, the heating block 9 generates heat, thereby heating the surrounding environment. The temperature-controlled sponge 10 is a special sponge material with good heat preservation properties, which effectively transfers heat to avoid low temperature from stimulating or damaging blood vessels and causing discomfort to the patient. The connector 5 plays an important role in connecting and supporting multiple components. The connector 5 is made of sturdy metal or high-performance plastic to ensure that the rotation limit block 6 can be stably rotated and connected therein. The outside of the injection tube 1 is fixedly connected to the connecting cylinder 17, and the inside of the sliding ring 11 is slidably connected to the outside of the connecting cylinder 17.

[0035] Reference Figure 2 , Figure 5 A rubber pad 12 is fixedly connected inside the connecting cylinder 17. The rubber pad 12 serves as a buffer and seal. When the sliding ring 11 slides on the connecting cylinder 17, the rubber pad 12 reduces friction and wear, and also prevents liquid from leaking from the gap between the connecting cylinder 17 and the sliding ring 11. A film 13 is fixedly connected to the outside of the connecting cylinder 17. The film 13 is a transparent plastic film with a certain degree of elasticity. Its function is to prevent external contaminants from entering the inside of the device, while not affecting the sliding operation of the sliding ring 11. A display screen 16 is fixedly connected to the outside of the sliding ring 11. The display screen 16 is a high-resolution liquid crystal display screen that can display various parameter information of the device, such as the temperature of the heating and temperature control components, the extension and retraction length of the catheter, etc., providing doctors with intuitive operation feedback. The angiography catheter 12 has an extension component inside for providing sliding. The extension component includes the angiography catheter 2 3. The angiography catheter 12 has multiple limiting grooves 14 inside.

[0036] Limiting rubber balls 15 are fixedly connected to the outer sides of the limiting groove 14. The size of the limiting groove 14 matches the limiting rubber balls 15, ensuring that the limiting rubber balls 15 can slide stably within them. The limiting rubber balls 15 are made of highly elastic rubber material and have elastic expansion and contraction. The limiting rubber balls 15 will move between different limiting grooves 14. When they move to a certain position, they will be stuck in the limiting groove 14, thereby limiting the further sliding of the angiography catheter 2 3 and playing a precise limiting role. The two limiting rubber balls 15 are externally slidably connected to the inside of multiple limiting grooves 14. The guide wire 4 is slidably connected inside the injection tube 1. The guide wire 4 is a key component for guiding the angiography catheter 2 3 into the blood vessel during interventional surgery. It is usually made of metal materials such as stainless steel or nickel-titanium alloy and has good flexibility and strength. The guide wire 4 is externally slidably connected to the outside of the angiography catheter 2 3. The outside of the angiography catheter 2 3 is externally slidably connected to the inside of the angiography catheter 1 2.

[0037] Working principle: First, the sliding ring 11 slides on the connecting cylinder 17, while the rotating limiting block 6 and the rotating block 8 are rotatably connected inside the connecting seat 5, ensuring that the doctor can flexibly adjust the position of the catheter according to the needs of the operation. The heating block 9 heats the catheter, and the temperature-controlling sponge 10 controls the temperature to avoid low temperature from stimulating or damaging the blood vessels. The adhesive fastening band 7 is used to fix the device on the surface of the rotating limiting block 6, thereby allowing the device to be fixed in different parts of the patient. When performing interventional surgery, the doctor first connects the injection tube 1 to the contrast agent and delivers the contrast agent to the contrast catheter 2 through the injection tube 1.

[0038] Secondly, the contrast catheter 2 achieves its telescopic function through its internal contrast catheter 3, which is limited by the limiting groove 14 and the limiting rubber ball 15. This allows the doctor to adjust the injection position of the contrast agent as needed, ensuring stable sliding and positioning of the catheter at different positions. At the same time, the membrane 13 prevents external contaminants from entering the device when the injection tube 1 is inserted. At this time, the guidewire 4 is guided into the blood vessel, ensuring that the contrast catheter 3 can be smoothly inserted and move along the direction of the blood vessel. During the operation, the doctor monitors various parameters of the device in real time through the display screen 16, such as temperature and the extension and retraction length of the catheter, to ensure the smooth progress of the operation, improve the operational flexibility and safety of interventional surgery, and ensure that the contrast agent can be accurately and effectively delivered to the target site.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
