Description

Technical Field

[0001] This utility model relates to the field of plasma electrode cutting tip technology, specifically a plasma electrode cutting tip. Background Technology

[0002] The working principle of a plasma cutting tip is to generate a high-temperature electric arc using a high-voltage current. The heat generated by the arc can instantly evaporate or melt the target tissue, thereby achieving precise cutting and coagulation. Specifically, the plasma cutting tip uses an ultra-low frequency stable electric field of 100kHz to excite an electrolyte (such as NaCl) into a low-temperature plasma with a thickness of approximately 100μm in front of the electrode. Under the action of the electric field, charged particles accelerate and gain sufficient kinetic energy to break molecular bonds, causing tissue decomposition, thereby achieving the vaporization and cutting of the tissue.

[0003] Currently, most cutting heads on the market are made by fixing the electrode plates with glue or thin metal wires. When energized, the electrode plates or wires will generate high temperatures, and under long-term working conditions, there is a risk that the electrode plates and wires will fall off. Utility Model Content

[0004] The purpose of this invention is to provide a plasma electrode tip to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plasma electrode tip, comprising an electrode sheet, a ceramic head, a stainless steel tube, an insulating tube, a ceramic suction tube, a suction tube, and an electrode conductive wire. The electrode sheet is integrally formed, and the contact surface between the electrode sheet and the tissue is convex. A groove is formed inside the ceramic head, and the electrode sheet is fixed inside the groove of the ceramic head with the assistance of adhesive and is adapted to the groove. The front end of the electrode conductive wire is fixed to the electrode sheet by welding.

[0006] Preferably, the ceramic suction tube passes through the ceramic head and is fixed to the ceramic head with the aid of glue, which supports and guides the ceramic suction tube. The electrode conductive wire passes through the ceramic head and is movably connected to the ceramic head, which limits and supports the electrode conductive wire.

[0007] Preferably, the suction tube passes through the ceramic head and is movably connected to the ceramic head. The suction tube is sleeved on the outside of the ceramic suction tube and is fixed to the ceramic suction tube with the aid of glue, thereby fixing the ceramic suction tube and the suction tube in place.

[0008] Preferably, the stainless steel tube is tightly fitted onto the outside of the ceramic head and fixed to the ceramic head with adhesive to fix and support the ceramic head.

[0009] Preferably, an insulating tube is integrally formed on the rear side of the stainless steel tube. The insulating tube is sleeved on the outside of the ceramic attraction tube, the attraction tube, and the electrode conductive wire, providing protection and support for the insulating tube, the ceramic attraction tube, the attraction tube, and the electrode conductive wire.

[0010] Preferably, a handle is fixedly connected to the rear end of the insulating tube, and a rubber pad is glued to the surface of the handle for easy gripping.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. The electrode sheet of this application is integrally molded with a raised design on the end face that contacts the tissue. This raised design facilitates plasma formation when energized. Compared to assembled electrode sheets, the integrally molded electrode sheet eliminates the risk of the electrode conductive wire or electrode sheet falling off during prolonged operation. Using a ceramic head as a carrier, the electrode sheet is inserted into the ceramic head and secured in the groove of the ceramic head with adhesive. The ceramic suction tube is inserted into the ceramic head and secured with adhesive. The electrode conductive wire is welded to the electrode sheet, ensuring a secure fixation and good conductivity.

[0013] 2.

It is used for the vaporization and cutting of tissue in local minimally invasive surgery. In the working state, electrical energy is introduced into the electrode plate through the electrode conductive wire to generate a plasma electric field, which excites the electrolyte into plasma. During the operation, the suction tube is connected to an external negative pressure device to draw out the turbid electrolyte and ensure a clear working field. Attached Figure Description

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.

[0022] Example 1: As Figures 1-4 As shown, this utility model provides a technical solution for a plasma electrode tip, including an electrode plate 1, a ceramic head 2, a stainless steel tube 3, an insulating tube 4, a ceramic suction tube 5, a suction tube 6, and an electrode conductive wire 7. The electrode plate 1 is integrally formed, and the cross-section of the electrode plate 1 in contact with the tissue is convex. A groove is formed inside the ceramic head 2. The electrode plate 1 is fixed inside the groove of the ceramic head 2 with the assistance of adhesive and is adapted to the groove. The front end of the electrode conductive wire 7 is fixed to the electrode plate 1 by welding. The ceramic suction tube 5 passes through the ceramic head 2 and is fixed to the ceramic head 2 with the assistance of adhesive, providing support and guidance for the ceramic suction tube 5. The electrode conductive wire 7 passes through the ceramic head 2 and is movably connected to the ceramic head 2, limiting the position of the electrode conductive wire 7. The support and suction tube 6 pass through the ceramic head 2 and are movably connected to the ceramic head 2. The suction tube 6 is sleeved on the outside of the ceramic suction tube 5 and is fixed to the ceramic suction tube 5 with the assistance of glue. The ceramic suction tube 5 and the suction tube 6 are fixedly installed. The stainless steel tube 3 is tightly sleeved on the outside of the ceramic head 2 and is fixed to the ceramic head 2 with the assistance of glue. This fixes and supports the ceramic head 2. An insulating tube 4 is integrally formed on the rear side of the stainless steel tube 3. The insulating tube 4 is sleeved on the outside of the ceramic suction tube 5, the suction tube 6 and the electrode conductive wire 7. It protects and supports the insulating tube 4, the ceramic suction tube 5, the suction tube 6 and the electrode conductive wire 7. A handle 8 is fixedly connected to the rear end of the insulating tube 4. A rubber pad is glued to the surface of the handle 8 for easy gripping.

[0023] In practical application, the plasma cutting head works by generating a high-temperature electric arc using a high-voltage current. The heat generated by the arc can instantly evaporate or melt the target tissue, thus achieving precise cutting and coagulation. Specifically, the plasma cutting head utilizes an ultra-low frequency stable electric field of 100kHz to excite the electrolyte into a low-temperature plasma with a thickness of approximately 100μm in front of the electrode. Under the influence of the electric field, charged particles accelerate, gaining sufficient kinetic energy to break molecular bonds, causing tissue decomposition, thereby achieving the vaporization and cutting of the tissue.

[0024] The electrode pad 1 in this design is integrally molded with a raised design on the end face that contacts the tissue. This raised design facilitates plasma formation when energized. Compared to assembled electrode pads, the integrally molded electrode pad 1 eliminates the risk of the electrode conductive wire 7 or the electrode pad 1 detaching during prolonged operation. Using the ceramic head 2 as a carrier, the electrode pad 1 is inserted into the ceramic head 2 and secured in a groove within the ceramic head 2 with adhesive. The ceramic suction tube 5 is inserted into the ceramic head 2 and secured with adhesive. The electrode conductive wire 7 is welded to the electrode pad 1, ensuring a secure fixation and good conductivity. The suction tube 6 is secured to the ceramic suction tube 5 with adhesive. The stainless steel tube 3 is assembled to the ceramic head 2 and secured with adhesive. This design is used for the vaporization and cutting of tissue in minimally invasive local surgery. In operation, electrical energy is introduced into the electrode pad 1 through the electrode conductive wire 7, generating a plasma electric field that excites the electrolyte into plasma. During surgery, the suction tube 6 is connected to an external negative pressure device to draw out turbid electrolyte, ensuring a clear working field.

[0025] Example 2: Figures 5-6 As shown, the stainless steel tube 3 and the ceramic suction tube 5 are designed in a curved shape, and the front end of the electrode conductive wire 7 is adapted to the ceramic suction tube 5 to accommodate different cutting conditions and to allow for different arm grip postures. This makes the plasma electrode tip more stable and reliable during use. The raised electrode plate 1 design not only enhances the plasma formation effect but also improves the accuracy of cutting and coagulation, ensuring the safety and efficiency of surgical operations. The plasma electrode tip of this application adopts an integrated molding technology, avoiding the risk of detachment that may exist in assembly, thereby extending the service life of the tip and reducing the failure rate during surgery. At the same time, the fixation methods such as glue-assisted fixation and welding ensure a firm connection and good conductivity between various components. This application also considers the actual needs during surgery, setting up curved components to adapt to different cutting conditions and providing a comfortable grip posture, further improving the convenience and comfort of surgical operations.
