[0028] Figure 1 An embodiment of a plasma radiofrequency ablation electrode system of the present application is shown.
[0029] Figure 1The plasma radiofrequency ablation electrode system shown includes: an electrode 101, the electrode includes:
[0030] The front end of the electrode includes a front working surface and a rear portion, and the front portion is composed of two inclined surfaces with a predetermined angle, wherein the first inclined surface is the RF working portion of the electrode, the second inclined surface is the plasma working portion of the electrode, and the area of the first inclined surface is smaller than the area of the second inclined surface;
[0031] a transmission line, one end of which is connected to a connector connecting the electrode and the electrosurgical device, and the other end of which is connected to the rear of the front end of the electrode, the transmission line providing corresponding working energy to the front end of the electrode, wherein the transmission line controls the working mode of the front end of the electrode by switching the action position of the working energy transmitted to the front end of the electrode; and
[0032] The electrosurgical device 102 controls the front end of the electrode to execute a radio frequency working mode or a plasma working mode by controlling the working mode of the transmission line, and provides corresponding energy to the front end of the electrode through the transmission line.
[0033] This specific implementation method can reduce the consumption cost of consumables (electrodes) during the operation by using the same device and the same electrode to simultaneously perform ablation and coagulation treatments, and can also simplify the surgical operation process, making clinical surgery more ideal.
[0034] Specifically, in actual application scenarios, the electrode is connected to an electrosurgical device through an interface that can display the electrode working mode and provide different frequency energies to the electrode, and the electrosurgical device may include an interactive interface or a switching switch to switch the electrode working mode. During surgery, when the electrode needs to be used for ablation, the electrosurgical device outputs energy that satisfies the plasma mode and transmits it to the second inclined surface at the front end of the electrode, and the second inclined surface is fitted with the part to be treated to complete the ablation treatment. When the electrode needs to be used for coagulation treatment, the electrosurgical device outputs energy that satisfies the radio frequency mode and transmits it to the first inclined surface at the front end of the electrode, and the first inclined surface is fitted with the part to be treated to complete the coagulation treatment, wherein the first inclined surface The inclination angle of the inclined surface can be 0°, 45° and 30°, the inclination angle of the second inclined surface can be 60°, 45° and 30°, and when the inclination angle of the first inclined surface is 0°, the inclination angle of the second inclined surface can be 60°, when the inclination angle of the first inclined surface is 45°, the inclination angle of the second inclined surface can be 30°, when the inclination angle of the first inclined surface is 45°, the inclination angle of the second inclined surface can also be 45°, and when the inclination angle of the first inclined surface is 30°, the inclination angle of the second inclined surface can be 45°. By setting the inclination angle of the first inclined surface and the inclination angle of the second inclined surface, and matching the angles between the two to obtain electrodes with different inclination angles, the electrodes can be suitable for surgical operations in different parts and of different types.
[0035] exist Figure 1 The plasma radio frequency ablation electrode system shown includes an electrode 101, an electrode front end, which includes a front working surface and a rear portion, and its front portion is composed of two inclined surfaces with a predetermined angle, wherein the first inclined surface is the radio frequency working part of the electrode, and the second inclined surface is the plasma working part of the electrode, and the area of the first inclined surface is smaller than the area of the second inclined surface.
[0036] In a specific embodiment of the present application, the transmission line includes: a hollow cylindrical transmission line, a common transmission line and a radio frequency transmission line, and the common transmission line and the radio frequency transmission line are insulated and placed in the inner hollow of the hollow cylindrical transmission line.
[0037] Furthermore, the working mode of the electrode front end is determined by determining the common working mode of the hollow cylindrical transmission line, the common transmission line and the radio frequency transmission line, wherein, when the common transmission line and the radio frequency transmission line in the transmission line work together, the electrode front end is in the radio frequency working mode; and, when the common transmission line and the hollow cylindrical transmission line in the transmission line work together, the electrode front end is in the plasma working mode.
[0038] Specifically, two mutually isolated transmission wires located in the hollow cylindrical transmission line work simultaneously, so that the electrode is in the radio frequency working mode and can transmit radio frequency energy to the first inclined surface; the plasma current is transmitted jointly by the common transmission line in the two transmission wires located inside the hollow cylindrical transmission line and the hollow cylindrical transmission line, so that the second inclined surface of the electrode can output plasma current. Because the operating frequency of the plasma radio frequency ablation electrode of the present application in the radio frequency mode is 1MHZ to 5MHZ, and its output power is 100W, and its operating frequency in the plasma mode is 100KHZ to 350KHZ, and its output power is 350W, therefore, by using the surface of the hollow cylindrical transmission line as the transmission line, the transmission area of the transmission line can be increased, the output of high-power current can be guaranteed, and the working effect of the electrode can be further guaranteed.
[0039] The transmission line includes a hollow cylindrical transmission line, a common transmission line and a radio frequency transmission line. The common transmission line and the radio frequency transmission line are insulated and placed in the hollow part of the hollow cylindrical transmission line, and one end of the transmission line is connected to the rear end connector of the electrode, and the other end of the transmission line is connected to the rear of the front end of the electrode, wherein when the common transmission line and the radio frequency transmission line in the transmission line work together, the front end of the electrode is in the radio frequency working mode, and when the common transmission line and the hollow cylindrical transmission line in the transmission line work together, the front end of the electrode is in the plasma working mode. When actual work is required, the two mutually isolated wires located inside the hollow cylindrical transmission line work at the same time, so that the electrode in the plasma radio frequency ablation electrode system of the present application is in the radio frequency working state; when the common wire located in the wire inside the hollow cylindrical transmission line works, and the hollow cylindrical transmission line also works at the same time, the common electrode and the plasma electrode work together to put the electrode in the plasma working state.
[0040] In a specific embodiment of the present application, the front end of the electrode is a cylindrical structure with a cross section of a predetermined diameter, and is tightly connected to the hollow cylindrical transmission line in the transmission line.
[0041] Specifically, Figure 2 FIG. 1 is a schematic diagram of an electrode of a plasma radiofrequency ablation system of the present application. Figure 2As shown, the front end of the electrode is a cylindrical structure with a predetermined diameter in cross section, and it is the signal sending end. It is composed of a cylindrical surface of a metal structure and a top surface with two inclined surfaces at a predetermined angle, wherein the first inclined surface is the RF working part of the electrode, the second inclined surface is the plasma working part of the electrode, and the area of the first inclined surface is smaller than the area of the second inclined surface. The reason why the working area of the second inclined surface is set to be larger than the area of the first inclined surface is that the energy required for the plasma working mode is greater than the energy required for the RF working mode. By setting the working surface as an inclined plane, the electrode of the present application can be more suitable for surgical treatment of uneven positions such as the knee, that is, it is easier to fit the electrode to the working part and ensure the fitting area, thereby ensuring the efficiency of the surgical treatment and the safety of the surgery. The front end of the electrode is sealed with the hollow cylindrical transmission line in the transmission line to ensure that in the plasma mode, the energy that can be transmitted by the transmission line and the front end of the electrode meets the working requirements. Preferably, the material of the metal structure is 304 stainless steel, and the diameter of the cross section of the electrode is 3.8mm to 4mm.
[0042] In a specific embodiment of the present application, the plasma radiofrequency ablation electrode also includes: a medium transmission and waste suction channel, which transmits the transmission medium required for the plasma working mode to the working part at the front end of the electrode when the electrode is working, or absorbs waste within the field of view.
[0043] Specifically, a medium transmission and waste absorption channel is provided on the electrode. The channel is used to transmit the medium required for the plasma current to the working part at the front end of the electrode when the electrode is working, or to absorb waste within the field of view, so as to ensure the clarity of the field of view during the operation. However, this structure is not a necessary structure. For example, when the electrode of the present application works in an endoscope with a channel, the channel can be omitted, and the channel of the endoscope with the channel can be directly used to transmit the medium required for the plasma current to work, or to absorb the accumulated fluid and tissue residues in the field of view during the operation. At the same time, when the plasma current is used for work, the medium material can be omitted and the accumulated fluid generated autonomously in the human body can be directly used as the medium, wherein the medium can be physiological saline.
[0044] In a specific embodiment of the present application, in a plasma radio frequency ablation system, the radio frequency working part is used to output radio frequency signals to achieve coagulation requirements during surgical operations, and the surface of the conductive cylindrical structure in the plasma working part and the front end of the electrode is used to output plasma current to achieve low-temperature ablation requirements during surgical operations.
[0045] Specifically, during the application process, the radio frequency working part is used to output radio frequency signals to achieve the coagulation requirements in the surgical operation, and the plasma working part and the conductive cylindrical surface in the front end of the electrode are used to output plasma current to achieve the low-temperature ablation requirements in the surgical operation, wherein the working temperature generated by the radio frequency working mode of the electrode of the present application is 40°C to 80°C, which can better stop bleeding at the bleeding point, and does not cause thermal damage to other parts such as nerve endings, thereby reducing nerve damage and reducing the patient's pain; the working temperature of the plasma working mode of the electrode of the present application is 40°C to 60°C, which can achieve ablation at a lower temperature, thereby reducing thermal damage. During the operation, the operator performs radio frequency working processing through the first inclined surface located on the side, which can make this part better contact with the tissue structure of the bleeding part, thereby achieving hemostasis more quickly, and does not require a medium and ionization to cause no damage to other parts. Plasma ablation is performed through the second inclined surface on the side and the conductive cylindrical surface in the front end of the electrode, which can better contact the part to be treated, and by increasing the effective contact area, it can ensure that high-power plasma current is supported while ensuring that the electrode has a larger effective area, so that large-area ablation operations such as bone plate ablation can be better performed. Preferably, the contact area of the plasma mode of the electrode of the present application can be selected and set according to user needs, that is, using the conductive cylindrical surface in the front end of the electrode to output plasma current is not a capability that the present application must have.
