A bipolar ablation electrode

Abstract

The invention discloses a novel bipolar ablation electrode. The electrode comprises an electrode tip, an electrode stem, a handle assembly, a weep pipe assembly and a cable assembly. The novel bipolarablation electrode is characterized in that the handle part of the electrode stem is connected with a built-in jack in the front end of the handle assembly; a built-in jack in the tail end of the handle assembly is connected with a buckle plug-in type cable assembly; a hollow tube structure is arranged in the electrode stem; a sealing ring (6) and a weeping tube are arranged between the electrodestem and the handle assembly; the sealing ring is connected with a capillary tube (4) at one end of the weeping tube arranged in the handle assembly; and a parallel silicone tube (12) is led out fromthe other end of the capillary tube (4) to be connected with the weeping tube assembly to form a built-in weeping pipeline. The novel bipolar ablation electrode is innovative in structure, reasonablein design, safe to use, convenient to operate, capable of achieving modular batch production, capable of saving cost and environmentally friendly in production process. The novel bipolar ablation electrode is suitable for medical instrument production enterprises to provide safe, reliable, convenient and fast hemostasis for surgical operations in batches.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bipolar ablation electrode. Background technique [0002] As an efficient and reliable hemostasis method, bipolar coagulation is widely used in various surgical operations. The basic principle of the bipolar ablation electrode is to clamp the blood vessel or tissue with the tip of the tweezers by pinching the tweezers, so that the high-frequency current passes through the local blood vessels or tissues clamped by the tip of the tweezers, and utilizes the thermal effect of the high-frequency current to make The blood vessel wall shrinks due to dehydration, the blood coagulates in the blood vessel, and makes the blood vessel and the blood clot merge into one, so as to achieve the purpose of hemostasis. To prevent the electrode tip from sticking to the tissue, some bipolar ablation electrodes are equipped with drip pipes on the tweezers to cool down the electrode tip to p...

Problems solved by technology

If there is no need to install the drip line, the above steps ②, ④, and ⑨ can be omitted; the above structure and production process have the following defects: ① During the slotting process of the tweezers blank, due to the small size of the stem of the tweezers blank, it is easy to deform, It is difficult to control the precision requirements of the depth and width of the groove; ②The tweezers and the electrode heads of the tweezers need to be manually ground or polished, and there are many factors affected by manual operation, so it is difficult to ensure consistency, and the edge of the tweezers blank is not well handled It has a great influence on the electrostatic powder spraying and forming, and it is easy to cause the voltage breakdown of this part, which brings great risks to the surgeon. Riveting, followed by gap filling and polishing, the efficiency is extremely low, and defective products are prone to appear; ④ It is necessary to manually wrap and shield the parts that do not need to be sprayed, and there are many factors affected by manual operation, so it is difficult to ensure consistency; ⑤ Electrostatic powder During the spraying process, affected by manual operation, the thickness and uniformity of the insulating powder are very poor, which cannot guarantee the safety of the withstand voltage, and the powder dust is not conducive to environmental protection and personnel health; ⑥The connection of cables and tweezers It is necessary to wait for most of the above work to be completed, and some need to be glued and fixed, and cannot be mass-produced independently by sub-components
