Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency cutting electrodes, in particular to a high-frequency cutting electrode which is convenient to assemble and disassemble. Background Art

[0002] The high-frequency resection electrode is a tool that plays an important role in specific fields. It is mainly used in medical or industrial scenarios. It uses high-frequency current to achieve the function of resection or processing specific substances. Its design is usually precise and professional, and can complete the resection task efficiently and accurately. For example, in medical surgery, the high-frequency resection electrode can accurately remove diseased tissue and reduce damage to surrounding healthy tissue. The performance and effect of this electrode depend on factors such as its material, shape and current frequency. High-quality high-frequency resection electrodes can improve the safety and success rate of operations.

[0003] Existing technologies include the utility model with publication number CN202682047U, which discloses a disposable high-frequency surgical electrode with a double-layer anti-high-frequency, high-pressure and waterproof structure. The patent adopts a face shell, a bottom shell, an electrode blade, a fixed surface and a control component. The structure design of the utility model is ingenious and reasonable. The control component is fixed on the fixed panel by ultrasonic welding to form an ultrasonic welding component 1, which achieves the first high-frequency, high-pressure and waterproof barrier. The fixed panel is fixed in the sealed accommodating cavity of the face shell by ultrasonic welding to form an ultrasonic welding component 2, which achieves the second high-frequency, high-pressure and waterproof barrier, thereby forming a double-layer anti-high-pressure and high-frequency effect. In addition, a waterproof ring is provided to achieve The waterproof function enables the utility model to effectively prevent medical personnel from being easily burned by high-frequency and high-voltage leakage during surgery when used in conjunction with high-frequency surgical equipment, and has high safety; it is beneficial for medical personnel to quickly and smoothly remove the part to be removed, greatly shortening the operation time and alleviating the patient's pain. Through wide promotion and application, it solves the problem that the existing high-frequency electric knife can meet the functions of cutting tissue and electric coagulation hemostasis, but its ability to resist high frequency and high voltage is weak. During the operation, the water generated by cutting or coagulation can easily adhere to and flow into the conductive area, causing high-voltage leakage, generating high-voltage arc burns to doctors and patients, and in severe cases, causing major medical accidents.

[0004] In the process of working with the help of high-frequency resection electrodes, most of the existing ones on the market are assembled through interference fit between the electrode blade and the operating handle. Since the surface of the electrode blade is relatively smooth and medical staff wear gloves during the operation, when the electrode blade needs to be disassembled and replaced during the operation, the interference fit between the electrode blade and the operating handle is too firm, and the electrode blade is smooth and difficult to hold, making it difficult for medical staff to disassemble the electrode blade when wearing gloves, which in turn increases the difficulty of disassembling the resection motor.

A push block 515 is slidably connected to the inner wall of the assembly box 511. Both sides of the push block 515 are fixedly connected to an extrusion plate 516.

[0025] The disassembly and assembly component 5 also includes a clamping unit 52, which includes a lower clamping plate 521, which is fixedly connected to the side surface of the connector 2, and the lower clamping plate 521 is in contact with the surface of the arc electrode 4. Both sides of the lower clamping plate 521 are fixedly connected with protrusions 522, and the surface of the protrusion 522 is rotatably connected to the connecting frame 523. The side surface of the connecting frame 523 is fixedly connected with a connecting arm 524, and the connecting arm 524 is arc-shaped on the side close to the connector 2. The surface of the connecting arm 524 is fixedly connected with an upper clamping plate 525, and the upper clamping plate 525 is in contact with the surface of the arc electrode 4. The side surface of the connecting plate 512 is fixedly connected with a linkage frame 526, and the side surface of the linkage frame 526 is fixedly connected with a fastening sleeve 527. The fastening sleeve 527 is socketed with the surface of the lower clamping plate 521, and the fastening sleeve 527 is socketed with the surface of the upper clamping plate 525.

[0026] Specifically, there are two positioning pins 513, and the two positioning pins 513 are symmetrically arranged with respect to the connecting plate 512. The side of the positioning pin 513 close to the push block 515 is chamfered. Through the positioning pin 513, the position of the connecting plate 512 in a limited state can be constrained under the action of the compression spring 514.

[0027] Specifically, there are two compression springs 514 , and the two compression springs 514 are symmetrically arranged front to back with respect to the positioning pin 513 .

[0028] In this embodiment, the position of the positioning pin 513 can be constrained by the compression spring 514 to ensure that the positioning pin 513 can achieve its own limiting effect.

[0029] Specifically, a receiving groove is opened on the inner wall of the assembly box 511, and the extrusion plate 516 is slidably connected to the inner wall of the receiving groove.

[0033] Working principle: When the resection motor is used, the negative electrode patch is pasted on the patient's body surface and connected to the host, and then the cable 1 is installed on the host to control the host to work. The host cooperates with the cable 1 to supply power to the connector 2. When the staff presses the operation button 3, the connector 2 supplies power to the arc electrode 4, and the arc electrode 4 is energized and works. The staff can resect the lesion through the arc electrode 4; when the arc electrode 4 needs to be replaced, the push block 515 is pushed, and the push block 515 cooperates with the squeezing plate 516 to squeeze the positioning pin 513. The positioning pin 513 squeezes the compression spring 514 under the action of the squeezing plate 516. The compression spring 514 is squeezed and deformed, and the positioning pin 513 disengages from the card hole and loses its shape. The restriction of the connecting plate 512 continues to be pushed by the pushing block 515. When the pushing block 515 reaches the side end of the connecting plate 512, the pushing block 515 pushes the connecting plate 512. The connecting plate 512 cooperates with the linkage frame 526 to pull the fastening sleeve 527. The fastening sleeve 527 is separated from the upper splint 525 and the lower splint 521. The upper splint 525 loses the restriction of the fastening sleeve 527 and loses the clamping effect on the arc electrode 4. The arc electrode 4 can be removed immediately. By setting the disassembly and assembly component 5, the disassembly operation of the cutting head of the resection electrode is more convenient, thereby reducing the problem that the connection between the cutting head and the handle is too firm during the operation, which is not conducive to the disassembly operation of medical staff, and further improves the disassembly and assembly efficiency of the resection electrode.
