Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a pressurization device for aspiration and ablation electrodes. Background Technology
[0002] The ablation electrode uses high-frequency electrical energy to generate heat, heating the diseased tissue to a high temperature, thus causing tissue necrosis. Simultaneously, a suction rod draws the necrotic tissue to the vicinity of the electrode for easy removal by surgical personnel. Existing ablation electrodes have a flushing function; medical staff press a button to output the flushing solution through an internal tube from the end. To further enhance the flushing effect, existing devices use an external booster pump to increase the flushing pressure; when increased pressure is needed, the booster pump is turned on. However, this technical solution requires connecting the ablation electrode to the booster pump, which is externally mounted on a wall or other location. Operators must walk over to turn on the booster pump, resulting in poor operational convenience and a high cost. Utility Model Content

[0024] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.
[0025] like Figures 1 to 6As shown, a pressurization device for aspiration and ablation electrodes in this embodiment includes a valve body 1, a button 2, a slider 3, and a spring 4. The valve body 1 is disposed in the handle 10. The valve body 1 includes a fluid inlet 11, a fluid outlet 12, and a valve chamber 13 that are interconnected. A first valve core 5 and a second valve core 6 are respectively provided in the fluid inlet 11 and the fluid outlet 12. The first and second valve cores are used to control the opening and closing of the fluid inlet 11 and the fluid outlet 12. The fluid inlet 11 and the fluid outlet 12 are respectively connected to a conduit. The cleaning fluid is input into the fluid inlet 11 through the conduit, and output through the fluid outlet 12 after passing through the valve chamber 13. The sliding member 3 is slidably disposed within the valve cavity 13. The sliding member 3 is connected to the button 2, which is located outside the handle 10. Pressing the button 2 causes the sliding member 3 to move within the valve cavity 13, pressurizing the fluid within the valve cavity 13. The first valve core 5 closes the fluid inlet 11, and the second valve core 6 opens. Thus, pressing the button 1 provides pressure, allowing the fluid within the valve body 1 to be rapidly discharged through the fluid outlet 12, enabling the ablation electrode to be flushed with a stronger impact cleaning fluid. The spring 4 is disposed within the valve body 1, with one end pressing against the sliding member 3. When the button is pressed, the spring 4 compresses and stores force; when the button is released, the spring drives the sliding member 3 to reset. In the above technical solution, in the initial state without pressing the button, the pressure of the cleaning fluid causes the first valve core 5 to open, and the cleaning fluid fills the valve cavity 13 through the fluid inlet 11, while the second valve core 6 closes. When pressurized flushing is required, the user presses button 2, and the slider 3 pushes the cleaning fluid in the valve chamber 13. At this time, the first valve core is pressured to close the fluid inlet 11, and the second valve core is pressured to open, allowing the cleaning fluid to be flushed out through the fluid outlet 12. This technical solution allows the user to manually control pressurized flushing when using the ablation electrode, making operation convenient; furthermore, it eliminates the need for an external pressurization pump, resulting in lower costs.
[0026] In this embodiment, the sliding member 3 has an annular cavity 31, the outer wall of which abuts against the inner wall of the valve cavity 13. One end of the spring 4 is disposed in the annular cavity 31, and the other end abuts against the inner wall of the valve cavity 13, thereby allowing the spring 4 to be stably disposed in the valve cavity 13 and the sliding member 3 to move smoothly. The sliding member 3 has a plug-in portion 32, which passes through the connection portion 21 between the valve body 3 and the button 2, facilitating the connection between the sliding member 3 and the button 2. The fluid inlet 11 and the fluid outlet 12 are disposed opposite to each other on the periphery of the valve body 3, with the directions of the fluid inlet 11 and the fluid outlet 12 perpendicular to the moving direction of the sliding member 3. The fluid flow direction is along the Y-axis, and the moving direction of the sliding member is along the X-axis. Through the above technical solution, when the fluid in the valve cavity 13 is pressurized, it can apply pressure to the two valve cores disposed opposite to each other, causing them to open the fluid outlet and close the fluid inlet, respectively.
[0027] In this embodiment, the valve body 1 includes a first tube 14 and a second tube 15. One end of the first tube 14 is inserted into the second tube 15, and the other end accommodates a connecting part 21. The fluid inlet 11 and the fluid outlet 12 are disposed on the second tube 15. The fluid inlet 11 is provided with a first sleeve 7, and the fluid outlet 12 is provided with a second sleeve 8 for easy connection to a conduit. The fluid inlet 11 is provided with a first baffle 111, and the first sleeve 7 is provided with an outlet 71. The first valve core 5 is movably disposed between the first baffle 111 and the outlet 71, thereby limiting the first valve core 5 and preventing it from being pushed into the valve cavity 13. The fluid outlet 12 is provided with a through hole 121, and the second valve core 6 opens or closes the through hole 121. The second sleeve 8 has a second baffle 81, which is located above the second valve core 6, thereby preventing the second valve core 6 from detaching from the fluid outlet 12. The fluid outlet 12 is located above the fluid inlet 11, so that when pressurization is applied, the second valve core 6 moves upward to open the fluid outlet 12, and the first valve core 5 moves downward to close the fluid inlet 11.
[0028] The pressurization device for flushing and ablation electrodes in this embodiment allows users to manually control the pressurization during flushing, making it convenient to operate; in addition, it eliminates the need for an external pressurization pump, resulting in lower costs.
[0029] The above description illustrates a pressurization device for aspiration and ablation electrodes according to this invention. However, this invention is not limited to the specific embodiments described above. Various modifications and alterations can be made without departing from the scope of the claims. This invention includes all modifications and alterations within the scope of the claims.
[0030] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features.
