Abstract

The present invention discloses a spider vein medical device and medical equipment that integrates radiofrequency ablation and sclerotherapy. Radiofrequency ablation therapy is achieved by providing an RF energy input terminal within a gripping portion, securing the puncture needle body and electrically connecting it to the first electrical connection terminal of an electrode conduction assembly. Furthermore, the second electrical connection terminal of the electrode conduction assembly is electrically connected to the RF energy input terminal when the assembly is mounted on the gripping portion. Furthermore, a clearance space is provided on the electrode conduction assembly to avoid the liquid conduction section at the tail end of the puncture needle body, allowing an injection line to be connected to the liquid conduction section. The injection line can then be connected to an external liquid injection device to achieve sclerotherapy. This embodiment allows sclerotherapy and radiofrequency ablation to be performed separately within the same punctured blood vessel, or separately within different blood vessels in the same region, thereby achieving combined treatment of spider veins using different surgical procedures.

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 are tiny capillaries within the skin. These red, blue, and purple capillaries are visible on the surface of the skin. These veins may carry either oxygen-poor venous blood (appears blue) or oxygen-rich arterial blood (appears red). As we age, the number of these veins increases, making them more noticeable on the skin. These "spider-web" veins may appear on the cheeks, around the nose, on the brow, on the forehead, and on the chin.

[0003] Currently, there are three main treatment options: sclerotherapy, laser therapy, and radiofrequency thermal ablation. Sclerotherapy is a more traditional treatment method, suitable for veins larger than 0.3mm in diameter. It involves injecting a sclerosing agent into the treated vein using a very fine needle to stimulate the formation of a blood clot, thereby blocking the vein and achieving complete vascular occlusion. This procedure requires a high level of physician experience and cannot be used by some patients who are allergic to sclerosing agents. Laser therapy, on the other hand, uses intense light pulses to damage the vein with heat. This heat causes scarring and ultimately closes the vein. It can cause pain, skin pigmentation (4.2%-50%), and blistering in the treated area. 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 clinician's eyes. 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 that appear 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 fibrosis, thereby achieving coagulation.

[0004] Currently, spider veins in different areas of the same patient have different diameters and sizes, and the appropriate treatment methods are also not exactly the same. During surgery, 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

[0037] The following is a detailed description of the spider vein medical device and apparatus for integrated radiofrequency ablation and sclerotherapy proposed by the present invention, with reference to the accompanying drawings and specific embodiments. The advantages and features of the present invention will become more apparent from the following description.

[0038] Example 1

[0039] See 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.

[0040] The holding portion is configured to have a radio frequency energy input end, which is used to output radio frequency energy.

[0041] A liquid channel is provided through the puncture needle body 1, and the puncture needle body 1 is configured to include a puncture working section, an electrical conduction section and a liquid path connecting section connected in sequence. The liquid path connecting section is connected to the output end of the injection pipeline 4, and the input end of the injection pipeline 4 is configured to be connected to an external liquid injection device, that is, the external liquid injection device inputs a preset liquid (hardening agent, etc.) into the injection pipeline 4 and outputs it from the puncture working section through the liquid channel.

[0042] 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 in the electrode conduction assembly to avoid the liquid path connection 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.

[0043] The puncture needle body 1 is configured to have a liquid injection configuration, a radiofrequency configuration, a first combined configuration, and a second combined configuration. In the liquid injection configuration, the puncture working section punctures the target object and injects a hardener at the target location through the liquid injection line 4 from the puncture end. In the radiofrequency configuration, the electrode conductive assembly is mounted on the handle, and the puncture working section punctures the target object and applies radiofrequency energy at the target location through the radiofrequency energy input end. In the first combined configuration, the electrode conductive assembly is mounted on the handle, and the puncture working section punctures the target object (the same blood vessel puncture point), and injects a hardener and applies radiofrequency energy to the target object through the liquid injection line 4 and the radiofrequency energy input end, respectively. In the second combined configuration, the electrode conductive assembly is mounted on the handle, and the puncture working section punctures different target objects (different blood vessels in the same spider vein area), and injects a hardener or applies radiofrequency energy to the target location of the corresponding target object through the liquid injection line 4 or the radiofrequency energy input end, respectively.

[0044] This embodiment provides a radiofrequency energy input terminal within the grip portion, wherein the puncture needle body 1 is fixed and electrically connected to the first electrical connection terminal of the electrode conduction assembly, and the second electrical connection terminal of the electrode conduction assembly is electrically connected to the radiofrequency energy input terminal when the assembly is mounted on the grip portion, thereby enabling radiofrequency ablation treatment. Furthermore, a clearance space is provided on the electrode conduction assembly to avoid the liquid conduction section at the tail end of the puncture needle body 1, allowing the injection line 4 to be connected to the liquid conduction section and achieve liquid conduction, thereby enabling the injection line 4 to be connected to an external liquid injection device to achieve sclerotherapy. Thus, the spider vein medical device of this embodiment can perform sclerotherapy and radiofrequency ablation treatment separately at the same punctured blood vessel, or perform sclerotherapy or radiofrequency ablation treatment separately in different blood vessels in the same area, thereby achieving combined treatment of spider veins with different surgical procedures. The appropriate treatment method can be selected based on the different locations and diameters of the patient's spider veins, simplifying the operation process and improving treatment efficiency.

[0045] 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 vein through the injection line 4 and the liquid channel, and then performing radiofrequency ablation above the spider vein through the electrically conductive puncture needle body 1 to induce vascular spasm and contraction. This procedure can reduce pigmentation and congestion after sclerotherapy.

[0046] The specific structure of the spider vein medical device integrating radiofrequency ablation and sclerotherapy of this embodiment is further described below:

[0047] In this embodiment, an intracavity electrical connector is provided in the grip portion for electrically conducting with an external RF generator. Specifically, the inner cavity of the grip portion is an installation cavity with an insertion opening, and the intracavity electrical connector is installed in the installation cavity.

[0048] In this embodiment, the electrode conductive assembly specifically includes an electrode holder and an electrode conductive body. The electrode holder 3 is provided with an electrode cavity extending therethrough (specifically, it can be configured to extend through both distal and proximal ends of the electrode holder 3), with the proximal end of the electrode holder 3 forming the holder insertion section. The electrode conductive body 2 is secured to the electrode cavity (specifically, this connection can be achieved using glue), and the proximal end of the electrode conductive body 2 extending beyond the holder insertion section forms the proximal conductive segment. The length of the proximal conductive segment matches the distance between the intracavitary electrical connector and the insertion opening. The holder insertion section is configured to be removably connected to the insertion opening and drive the proximal conductive segment to adhere to the intracavitary electrical connector, establishing electrical connection. Specifically, after the electrode holder 3 is attached to the grip, the intracavitary electrical connector and the electrode conductive body 2 are electrically connected. Furthermore, because the conductive segment of the puncture needle body 1 is clamped to the electrode conductive body 2, radiofrequency energy generated by an external radiofrequency generator can be transmitted to the puncture needle body 1 through the intracavitary electrical connector and the electrode conductive body, allowing the puncture working section to perform radiofrequency thermal ablation.

[0049] In this embodiment, the electrode conductor 2 includes a clamping section, an intermediate transition section, and a proximal conductive section, which are connected in sequence. The intermediate transition section is located within the electrode cavity. The clamping section is clamped to the conductive section (i.e., the puncture needle body 1 and the electrode conductor 2 are welded and connected at this location to achieve electrical conduction). A clearance groove is provided in the intermediate transition section to form a clearance space within the electrode cavity (i.e., the intermediate transition section only occupies a portion of the space within its corresponding electrode cavity, and the unoccupied portion is the clearance space, which is formed by the cooperation between the intermediate transition section and the electrode holder 3). The liquid path connecting section of the puncture needle body extends from the clamping section and extends into the clearance space, connecting to the output end of the injection pipeline 4.

[0050] Furthermore, the electrode holder 3 is provided with a through hole extending to the avoidance space, and the injection pipeline 4 penetrates into the avoidance space through the through hole. The liquid connection section between the injection pipeline 4 and the puncture needle body can be sealed and fixed by glue.

[0051] In this embodiment, the above-mentioned electrode conductor 2 can be specifically an open electrode ring 10 (that is, the electrode conductor 2 is tubular and has 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 open electrode ring 10 is made of metal sheet. 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). The end of the proximal conductive section is provided with a transition bevel for inserting the inner ring of the open electrode ring 10. The minimum diameter formed by the transition bevel is smaller than the inner ring diameter of the open electrode ring 10, so as to facilitate the insertion operation.

[0052] 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 means of bolts, thereby keeping the position of the open electrode ring 10 stable.

[0053] 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 the mounting block. The end of the cable 8 is provided with a plug 9, which can be connected to an external RF generator through the plug 9 to realize the input of RF energy.

[0054] In this embodiment, the open groove design of the open electrode ring 10 enables the open electrode ring 10 to be expandable and have an inward clamping force in the expanded state, so that the electrode conductor 2 and the open electrode ring 10 have an interference fit to achieve electrical conduction. In addition, the damping generated by the interference fit enables the electrode conductor 2, the electrode seat 3, the puncture needle body 1, etc. to be smoothly plugged and unplugged as a whole, and not easily fall off.

[0055] In this embodiment, the gripping 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 mounting cavity is formed between the upper shell 6 and the lower shell 7.

[0056] In this embodiment, the input end of the injection line 4 may be provided with an external interface, which may be a Luer port 5 for connection to an external medical device. The outer wall of the upper housing 6 may be provided with an interface mounting seat for detachably connecting to the external interface. The interface mounting seat may specifically form a slot into which the Luer port 5 can be inserted for securement.

[0057] In this embodiment, the insertion opening is a tubular mounting section arranged at the far 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.

[0058] In this embodiment, since the connection between the electrode holder 3 and the holding part is pluggable, in order to facilitate installation, the distal end of the electrode holder 3 is an installation operation section, and the installation operation section is provided with a friction protrusion, which can be specifically a number of protrusion rings arranged at intervals for easy plugging and unplugging.

[0059] The working principle of the spider vein medical device integrating radiofrequency ablation and sclerotherapy of this embodiment is described below:

[0060] The electrode assembly comprises a puncture needle body 1, an electrode conductor 2, an electrode holder 3, an injection line 4, and a Luer connector 5. The puncture needle body 1 is inserted into the grip, and the electrode conductor 2 is securely locked by an open electrode ring 10 within the grip. Electrical conduction is then achieved by welding a cable 8, a plug 9, and the open electrode ring 10. A hardener is injected from a syringe through the Luer connector 5 into the injection line 4. Under the pressure of the syringe, the hardener flows from the injection line 4 into the puncture needle body 1. After the puncture needle body 1 injects the hardener into the spider vein, a radio frequency generator transmits radio frequency energy to the cable 8 through the plug 9. Since the cable 8 is electrically connected to the open electrode ring 10, the electrode conductor 2, and the puncture needle body 1, radio frequency energy is transmitted to the puncture needle body 1. 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, causing the blood vessels to constrict, thereby curing the spider veins.

[0061] This embodiment can realize a new procedure of combining sclerotherapy with radiofrequency. A sclerosant can be injected into the corresponding area of ​​the spider vein 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 vein through the electrically conductive puncture needle body 1 to promote vascular spasm, produce contraction, and complete vascular closure. This procedure can reduce pigmentation and congestion after sclerotherapy.

[0062] Furthermore, this embodiment integrates radiofrequency thermal ablation and sclerotherapy, allowing for the selection of appropriate treatment methods based on the patient's spider veins, regardless of their location and diameter. This eliminates the need for instrument replacement, reduces surgical costs, simplifies the procedure, and improves treatment efficiency. When using radiofrequency thermal ablation, the electrode holder 3 is inserted into its corresponding grip, completing the electrical connection to achieve thermal ablation of the spider veins. When sclerotherapy is required, the electrode holder 3 can be removed from the handle and the Luer connector 5 connected to a syringe to inject the sclerosant, enabling the use of either radiofrequency therapy or sclerotherapy alone.

[0063] Example 2

[0064] This embodiment provides a medical device comprising a sclerosant injector, a radiofrequency generator, and the spider vein medical device for integrated radiofrequency ablation and sclerotherapy described in the first embodiment above. The spider vein medical device comprises a needle body and a handheld portion, wherein an intracavity electrical connector is disposed within a mounting cavity having an insertion opening in the handle, and an electrode holder 3 is disposed that matches the insertion opening. An electrode conductor 2 and a puncture needle body 1 are disposed within the electrode holder 3. The puncture needle body 1 is held by the electrode conductor 2, and a proximal conductive section of the electrode conductor 2 is configured to abut and electrically connect with the intracavity electrical connector when the electrode holder 3 is mounted to the handle. This allows radiofrequency energy generated by the radiofrequency generator to be transmitted to the puncture needle body 1 via the intracavity electrical connector and the electrode conductor 2, thereby achieving radiofrequency ablation treatment. Furthermore, a liquid channel is disposed within the puncture needle body 1 and is connected to an injection line 4 extending into the electrode cavity. Thus, an external interface on the injection line 4 can be connected to the sclerosant injector to achieve sclerotherapy. This creates a new procedure for sclerotherapy combined with radiofrequency ablation for spider veins. Through the injection line 4 and the liquid channel, a sclerosant is injected into the corresponding area of ​​the spider vein, gradually fibrosing the vessel wall. Radiofrequency ablation is then performed in the corresponding treatment area of ​​the spider vein using the electrically conductive puncture needle body 1, inducing vasospasm, contraction, and complete vascular closure. This procedure can reduce post-sclerotherapy pigmentation and congestion. Furthermore, this embodiment allows for the selection of appropriate treatment methods based on the patient's spider veins, regardless of their location and diameter. This eliminates the need for instrument replacement, reduces surgical costs, simplifies the procedure, and improves treatment efficiency.
