Description

Technical Field

[0001] The present invention belongs to the technical field of medical devices, and in particular relates to a spider vein medical device and medical equipment integrating radiofrequency ablation and sclerotherapy. Background Art

[0002] Spider veins refer to the capillaries in the skin. Red, blue and purple capillaries can be seen on the surface of the skin. These veins may carry either low-oxygen venous blood (blue) or oxygen-rich arterial blood (red). As you age, the number of blood vessels increases and they become more noticeable on the skin. The "spider-web"-like blood veins may appear on the cheeks, around the nose, on the brow, on the forehead and on the chin.

[0003] There are three main treatment methods at present: sclerotherapy, laser therapy and radiofrequency thermal ablation. Sclerotherapy is a more traditional treatment method, suitable for veins with a diameter greater than 0.3mm. Its treatment principle is to inject a sclerosant into the vein to be treated through an extremely fine puncture needle to stimulate the formation of a blood clot to block it, thereby completing the vascular occlusion. This procedure has high requirements for the doctor's operating experience, and some patients who are allergic to sclerosants cannot use it; laser therapy uses intense light pulses to destroy veins with heat. The heat causes scar formation and eventually closes the veins. It can cause pain in the treatment area, skin pigmentation (4.2%-50%) and blister formation. In severe cases, it can cause skin necrosis and ecchymosis. Compared with injection treatment, laser treatment is expensive. If the treatment is not thorough after surgery, there is a possibility of recurrence. The laser energy will also irritate the eyes of clinicians. Radiofrequency thermal ablation is an emerging technology in recent years. It is significantly better than sclerotherapy and laser treatment for superficial, small, red (less than 0.3mm in diameter) spider veins, especially spider veins on the face (on the nose, around the nose, and on the cheeks) and legs. The treatment principle is to puncture extremely fine electrodes into the inner wall of the blood vessel. The radiofrequency energy at the electrode acts on the tissue, causing the blood vessels to contract and fibrose, thereby achieving coagulation.

[0004] Currently, the diameters of spider veins in different areas of the same patient are different, and the appropriate treatment methods are not exactly the same. During the operation, different surgical procedures are often required for treatment. However, existing related medical devices can only perform a single treatment method and cannot adapt to spider veins of different sizes in the same area. The treatment is relatively limited, the surgical cost is high, and the treatment efficiency is low. Summary of the invention

[0020] The following is a further detailed description of a spider vein medical device and medical equipment integrating radiofrequency ablation and sclerotherapy proposed by the present invention in conjunction with the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description.

[0021] Embodiment 1 See also Figures 1 to 10 A spider vein medical device integrating radiofrequency ablation and sclerotherapy includes a gripping portion, a puncture needle body 1, an injection pipeline 4 and an electrode conduction component.

[0022] The holding portion is configured to have a radio frequency energy input terminal, and the radio frequency energy input terminal is used to output radio frequency energy.

[0024] The first electrical connection end of the electrode conduction assembly is fixedly connected to the electrical conduction section and is electrically conductive, and a avoidance space is provided inside the electrode conduction assembly to avoid the liquid path connecting section and at least part of the injection pipeline 4. The electrode conduction assembly is configured to be detachably mounted on the holding portion, and in the installed state, the second electrical connection end of the electrode conduction assembly is electrically conductive to the radio frequency energy input end, that is, electrical conduction between the radio frequency energy input end and the puncture needle body 1 is achieved through the first electrical connection end and the second electrical connection end, so that the radio frequency energy can be transmitted to the puncture working section.

[0025] The puncture needle body 1 is configured to have a liquid injection configuration, a radio frequency configuration, a first composite configuration, and a second composite configuration. In the liquid injection configuration, the puncture working section punctures into the target object, and injects a hardener from the puncture end at the target position through the liquid injection pipeline 4. In the radio frequency configuration, the electrode conduction assembly is mounted on the grip, the puncture working section punctures into the target object, and applies radio frequency energy from the puncture working section at the target position through the radio frequency energy input end. In the first composite configuration, the electrode conduction assembly is mounted on the grip, the puncture working section punctures into the target object (the same blood vessel puncture point), and injects a hardener and applies radio frequency energy to the target object through the liquid injection pipeline 4 and the radio frequency energy input end. In the second composite configuration, the electrode conduction assembly is mounted on the grip, the puncture working section punctures into different target objects (different blood vessels in the same spider vein area), and injects a hardener or applies radio frequency energy at the target position of the corresponding target object through the liquid injection pipeline 4 or the radio frequency energy input end.

[0026] In this embodiment, a radio frequency energy input terminal is arranged in the gripping part, the puncture needle body 1 is fixed and electrically connected to the first electrical connection terminal of the electrode conduction component, and the second electrical connection terminal of the electrode conduction component is electrically connected to the radio frequency energy input terminal when the component is installed in the gripping part, thereby realizing radio frequency ablation treatment; and, a space for avoiding the liquid path conduction section at the tail end of the puncture needle body 1 is arranged on the electrode conduction component, so that the injection line 4 can be connected to the liquid path conduction section and realize liquid path conduction, and then the injection line 4 can be connected to the external liquid injection device to realize sclerotherapy. Therefore, the spider vein medical device of this embodiment can perform sclerotherapy and radio frequency ablation treatment at the same punctured blood vessel, or perform sclerotherapy or radio frequency ablation treatment in different blood vessels in the same area, thereby realizing the combination treatment of spider veins by matching different surgical procedures, and can select appropriate treatment methods according to different parts of the patient and spider veins of different diameters, thereby simplifying the operation process and improving the treatment efficiency.

[0027] Furthermore, the embodiment can form a new procedure for sclerotherapy combined with radiofrequency for spider veins, that is, first injecting a sclerosant into the spider veins through the injection line 4 and the liquid channel, and then performing radiofrequency ablation above the spider veins through the electrically conductive puncture needle body 1 to induce vascular spasm and contraction. This procedure can reduce pigmentation and congestion after sclerotherapy.

[0028] The specific structure of the spider vein medical device integrating radiofrequency ablation and sclerotherapy of this embodiment is further described below: In this embodiment, an intracavity electrical connector for electrically connecting to an external radio frequency generating device is provided in the gripping portion. Specifically, the inner cavity of the gripping portion is an installation cavity with an insertion opening, and the intracavity electrical connector is installed in the installation cavity.

[0029] In this embodiment, the electrode conduction assembly may specifically include an electrode holder and an electrode conductor. The electrode holder 3 is provided with an electrode cavity that penetrates through it (specifically, it can be set to penetrate through the far and near ends of the electrode holder 3), and the proximal end of the electrode holder 3 is the holder insertion section. The electrode conductor 2 is fixed to the electrode cavity (specifically, it can be fixedly connected by glue), and the proximal end of the electrode conductor 2 extending out of the holder insertion section is the proximal conduction section, and the length of the proximal conduction section matches the spacing between the intracavitary electrical connector and the insertion opening. Among them, the holder insertion section is configured to be detachably connected to the insertion opening and drive the proximal conduction section to fit the intracavitary electrical connector and be electrically conductive, that is, after the electrode holder 3 is installed on the gripping part, the intracavitary electrical connector is electrically connected to the electrode conductor 2. And because the electrical conduction section of the puncture needle body 1 is clamped in the electrode conductor 2, the radio frequency energy generated by the external radio frequency generating device can be transmitted to the puncture needle body 1 through the intracavitary electrical connector and the electrode conductor, and the radio frequency thermal ablation is performed by the puncture working section.

[0030] In this embodiment, the electrode conductor 2 includes a clamping section, an intermediate transition section and a proximal conductive section connected in sequence, and the intermediate transition section is located in the electrode cavity. The clamping section is clamped in the electrical conductive section (that is, the puncture needle body 1 and the electrode conductor 2 are welded and connected at this location to achieve electrical conduction). An avoidance groove is provided on the intermediate transition section to form an avoidance space located in the electrode cavity (that is, the intermediate transition section only occupies a part of the space in the corresponding electrode cavity, and the unoccupied part is the avoidance space, which is formed by the cooperation of the intermediate transition section and the electrode seat 3). The liquid path connecting section of the puncture needle body extends from the clamping section and extends into the avoidance space and is connected to the output end of the injection pipeline 4.

[0031] Furthermore, the electrode holder 3 is provided with a through hole penetrating to the avoidance space, and the injection pipeline 4 penetrates into the avoidance space through the through hole. The liquid path connecting section of the injection pipeline 4 and the puncture needle body can be sealed and fixed by glue.

[0032] In the present embodiment, the electrode conductor 2 may be specifically an open electrode ring 10 (i.e., the electrode conductor 2 is tubular and is provided with an open groove extending in the axial direction), the inner ring diameter of the open electrode ring 10 is smaller than the outer ring diameter of the proximal conductive section (the material of the open electrode ring 10 is a metal sheet, and when the proximal conductive section is inserted into the open electrode ring 10, the open electrode ring 10 is stretched and deformed and tightly clamps the proximal conductive section, thereby achieving stable electrical conduction), and a transition slope for inserting the inner ring of the open electrode ring 10 is provided at the end of the proximal conductive section, and the minimum diameter formed by the transition slope is smaller than the inner ring diameter of the open electrode ring 10, so as to facilitate the insertion operation.

[0033] Furthermore, a mounting block may be extended from the open electrode ring 10 , and the mounting block may be fixed relative to the holding portion by bolts, thereby keeping the position of the open electrode ring 10 stable.

[0034] Furthermore, the open electrode ring 10 can also be electrically connected to a cable 8, which can be connected to the open electrode ring 10 or to a mounting block. A plug 9 is provided at the end of the cable 8, which can then be connected to an external RF generator through the plug 9 to achieve the input of RF energy.

[0035] In this embodiment, the open groove design of the open electrode ring 10 realizes that the open electrode ring 10 can be expanded and has an inward clamping force in the expanded state, so that the electrode conductor 2 and the open electrode ring 10 are interference fit to achieve electrical conduction, and the damping generated by the interference fit makes the electrode conductor 2 and the electrode seat 3, the puncture needle body 1, etc. The whole can be smoothly plugged in and out, and is not easy to fall off.

[0036] In this embodiment, the holding portion may specifically include an upper shell 6 and a lower shell 7. The upper shell 6 and the lower shell 7 may be assembled by interference fit in the form of structural positioning columns and positioning pins. The above-mentioned installation cavity is formed between the upper shell 6 and the lower shell 7.

[0037] In this embodiment, an external interface may be provided at the input end of the injection pipeline 4, and the external interface at the input end of the injection pipeline 4 may be provided as a Luer interface 5, so as to be connected to an external medical device. An interface mounting seat for detachably connecting the external interface may be provided on the outer wall surface of the upper shell 6, and the interface mounting seat may specifically form a card slot, and the Luer interface 5 may be inserted into the card slot for fixation.

[0038] In this embodiment, the insertion opening is a tubular mounting section arranged at the distal end of the gripping portion (specifically, it can be arranged on the lower shell 7), and the inner ring surface of the tubular mounting section is configured to be interference fit with the seat body insertion section, that is, the insertion guidance and relative position fixation between the electrode holder 3 and the lower shell 7 are achieved through the cooperation between the tubular mounting section and the seat body insertion section.

[0039] In this embodiment, since the connection between the electrode holder 3 and the holding portion is pluggable, in order to facilitate installation, the distal end of the electrode holder 3 is an installation operation section, and a friction protrusion is provided on the installation operation section, which can be specifically a plurality of protrusion rings arranged at intervals, for easy plugging and unplugging.

[0040] The working principle of the spider vein medical device integrating radiofrequency ablation and sclerotherapy of this embodiment is described below: The electrode needle assembly is composed of a puncture needle body 1, an electrode conductor 2, an electrode seat 3, an injection pipeline 4, and a Luer interface 5. The puncture needle body 1 is inserted into the gripping part, and the electrode conductor 2 is firmly locked by the open electrode ring 10 inside the gripping part, and then the electrical conduction is achieved by welding the cable 8, the plug 9, and the open electrode ring 10. The hardener is injected from the syringe into the injection pipeline 4 through the Luer interface 5. Under the action of the syringe pressure, the hardener flows from the injection pipeline 4 into the puncture needle body 1. After the puncture needle body 1 injects the hardener into the spider vein, the radio frequency generator transmits radio frequency energy to the cable 8 through the plug 9. Since the cable 8 is electrically connected with the open electrode ring 10, the electrode conductor 2, and the puncture needle body 1, that is, the radio frequency energy is transmitted to the puncture needle body 1, and the puncture working section of the puncture needle body 1 is inserted into the vein. The radio frequency energy at the electrode acts on the tissue to shrink the blood vessel, thereby curing the spider vein.

[0041] This embodiment can realize a new procedure of sclerotherapy combined with radiofrequency. A sclerosant can be injected into the corresponding area of ​​the spider veins through the injection pipeline 4 and the liquid channel to gradually fibrosize the blood vessel wall there, and radiofrequency ablation can be performed in the corresponding treatment area of ​​the spider veins through the electrically conductive puncture needle body 1 to induce vascular spasm, produce contraction, and complete blood vessel closure. This procedure can reduce pigmentation and congestion after sclerotherapy.

[0042] In addition, this embodiment integrates radiofrequency thermal ablation and sclerotherapy into one, and can select appropriate treatment methods according to different parts of the patient and spider veins of different diameters. There is no need to replace instruments, which reduces surgical costs, simplifies the operation process, and improves treatment efficiency. When using radiofrequency thermal ablation, insert the electrode holder 3 into its matching gripping part to complete the electrical connection, and thermal ablation of spider veins can be achieved. When sclerotherapy is needed, the electrode holder 3 can be removed from the handle, and the Luer interface 5 can be connected to the syringe to achieve the injection of the sclerosant to match the scenario of using radiofrequency treatment or sclerotherapy alone.

[0043] Embodiment 2 This embodiment provides a medical device, including a hardener injector, a radio frequency generator, and the spider vein medical device integrating radio frequency ablation and hardening therapy in the above-mentioned embodiment 1. The spider vein medical device is provided by separating the needle body part and the handheld part, providing an intracavity electrical connector in the mounting cavity with an insertion opening in the gripping part, and providing an electrode holder 3 matching the insertion opening, and providing an electrode conductor 2 and a puncture needle body 1 in the electrode holder 3, the puncture needle body 1 is clamped by the electrode conductor 2, and the proximal conductive section of the electrode conductor 2 is configured to be attached to and electrically connected with the intracavity electrical connector when the electrode holder 3 is installed in the gripping part, so that the radio frequency energy generated by the radio frequency generator can be transmitted to the puncture needle body 1 via the intracavity electrical connector and the electrode conductor 2 to achieve radio frequency ablation treatment, and the puncture needle body 1 is provided with a liquid channel, which is connected to the injection line 4 extending into the electrode cavity, and the external interface on the injection line 4 can be connected to the hardener injector to achieve hardening therapy. A new procedure for sclerotherapy combined with radiofrequency for spider veins is formed, that is, a sclerosant is injected into the corresponding area of ​​the spider veins through the injection pipeline 4 and the liquid channel to gradually fibrosis the blood vessel wall there, and radiofrequency ablation is performed in the corresponding treatment area of ​​the spider veins through the electrically conductive puncture needle body 1, so as to induce vascular spasm, contraction, and complete vascular closure. This procedure can reduce pigmentation and congestion after sclerotherapy.
