Description

Acupuncture Needle Type Radio Frequency Electro Acupuncture

technical field

The utility model relates to the technical field of radio frequency medical treatment, in particular to an acupuncture needle type radio frequency electric acupuncture.

Background technique

Radiofrequency ablation (RFA) is a minimally invasive interventional treatment method. In 1990, Rossi and Mcgahan first reported that RFA was applied to the ablation of animal liver tissue, and then used this technology to treat human liver tumors. At present, RFA technology has been widely used in the treatment of diseases in various organs of the body. In addition to inactivating tumors, it can also reduce tumor burden to relieve pain and reduce hormone secretion. Hypersplenism (hypersplenism), benign thyroid nodules, supraventricular tachycardia, atrial fibrillation, etc. RFA is a hyperthermia method. Its basic principle is to use thermal energy to damage the diseased tissue, and the electrodes emit radio frequency waves to make the ions and polar macromolecules in the surrounding tissue oscillate and collide with friction to generate heat, and the diseased tissue is heated to the effective therapeutic temperature range. Maintaining it for a certain period of time can cause coagulation and necrosis of the tissue, so as to achieve the purpose of locally inactivating the tissue. At the same time, the thermal effect of radio frequency can coagulate the blood vessels in the surrounding tissue, forming a reaction zone, so that it cannot supply blood to the tumor and prevent tumor metastasis.

The thermal effect produced by radiofrequency ablation varies with different tissues. Irreversible cell necrosis can occur due to protein coagulation at temperatures >60°C. When the temperature is >100°C, the tissue is carbonized and evaporated, which reduces the electrical and heat conduction. When the temperature of the target organ was 60-100°C and the time was 5-10 minutes, the necrosis diameter of single-needle electrode tumor ablation was 15mm. The generally used monopolar electrode is used for lesions with a diameter of <3 cm. The radiofrequency ablation time is 5-10 minutes, and the core temperature is 100°C or until the temperature cannot be transmitted to the target tissue. Increasing the power output cannot increase the ablation range.

In order to increase the ablation range, the utility model umbrella-shaped electrode increases the area of the electrode tip and the inner cooling electrode (air circulation and water circulation electrode). Umbrella-shaped electrode accommodates multiple umbrella ribs, and there are temperature detectors and microtubes for cooling air or saline in the inner cooling electrode to reduce the temperature of the needle tip, avoid carbonization of the tissue around the needle tip, improve tissue conductivity, and make the tumor necrosis area more stable Large, necrotic area can reach 50mm. However, thicker electrode needles are usually required, which increases the risk of trauma, complications, and bleeding.

The needle body diameter of traditional ablation needles/radiofrequency needles generally ranges from 1.0-1.9mm to ensure a certain strength and facilitate penetration into deep lesion parts. The insulating material of the needle body insulation section is mostly sleeves and heat shrinkable tubes. The size is above 0.025mm, and the needle body diameter of acupuncture needle type radio frequency electroacupuncture is 0.1mm-0.5mm. The insulating layer is a coating material, the wall thickness is 0.010mm-0.050mm, and the withstand voltage value is above 2000V and within 3500V.

Utilizing the characteristics of the fine size of acupuncture needles, the thinness of the insulating coating reduces the diameter of the entire needle. It has many advantages such as less injury, less pain, lower risk of complications and bleeding, and repeatable operation. It is especially suitable for patients with fine lesions and correspondingly higher risk of bleeding.

For the control of the ablation range, the ablation range of the traditional ablation needle/RF needle is controlled within 2.5cm-4.5cm. Acupuncture needle-type radiofrequency electroacupuncture single-needle ablation range control precision range 2mm-6mm. Using the characteristics of acupuncture needles combined with its size and needle body toughness, an acupuncture needle-type RF electroacupuncture with high precision in the target range was designed.

Contents of the invention

The purpose of the utility model is to provide an acupuncture needle-type radio-frequency electric needle, the handle of the needle body can be connected with medical high-frequency equipment such as an electric stimulator, an electrocoagulation instrument, a radio frequency instrument, and a microwave instrument.

The material of the anti-puncture insulating coating 4 is stainless steel stone coating, Teflon or parylene, and the English name of parylene is Parylene. Processing conditions of parylene: room temperature about 30 degrees

The thickness of the anti-puncture insulating coating 4 is 0.010mm-0.050mm, and its withstand voltage range is above 2000V and within 3500V.

The needle body 1 is made of medical 304 stainless steel with a diameter of 0.1mm-0.5mm.

The needle body 1 is also provided with a scale marking segment 3, and the scale marking segment 3 is located between the outer surface of the needle body 1 and the breakdown-resistant insulating coating 4, or the scale marking segment 3 is located on the outer surface of the breakdown-resistant insulating coating 4, or The scale marking segment 3 is located within the anti-puncture insulating coating 4 .

The scale marking segment 3 is arranged on the needle body 1 by spraying, printing, laser marking or corrosion marking. The scale mark is used to calculate the depth and accurately locate the needle tip RF output end to reach the lesion site.

The acupuncture needle-type radio-frequency electric acupuncture also includes a single-needle fixed positioning seat 8 or a multi-needle fixed seat 9 that can be set outside the needle body 1. The single-needle fixed positioning seat 8 is sleeve-shaped, and the multi-needle fixed positioning seat 9 Contains multiple pipes that can be inserted into the needle body 1 , or the multi-needle fixed positioning seat 9 is composed of multiple single-needle fixed positioning seats 8 . Because the acupuncture needle type RF electroacupuncture is slender and tough enough, but not strong enough, it is easy to bend and deflect when directly inserted. Add a fixed positioning seat before entering the skin, avoid the deviation of the needle insertion direction by rotating, and ensure that it moves in the direction fixed by the fixed positioning seat. Combined with the scale mark on the needle body, calculate the depth and accurately operate the needle tip RF output end to reach the lesion. The multi-needle fixed positioning seat has the same function as the single-needle fixed positioning seat. At the same time, because the acupuncture needle type radio frequency electroacupuncture is slender, the ablation range is small, and the diameter is about 5-6mm. For larger lesions, the multi-needle fixed positioning seat can be used for multi-needle phase Neighbors, fusion and ablation. The multiple single-needle pipelines in the multi-needle fixed positioning seat are distributed in pentagonal, hexagonal and quincunx shapes.
