[0031] Radiofrequency surgical electrodes will generate a large amount of smoke when used, which will have a certain impact on the doctor's vision and affect the progress of the operation. Therefore, it is urgent to propose a radiofrequency surgical electrode with smoke exhaust function.

[0032] Based on this, the utility model proposes a radiofrequency surgical electrode with a smoke extraction function. In order to prevent smoke from interfering with the surgical process, a smoke extraction channel is provided inside the sheath tube, and the smoke extraction channel is connected with the cavity. By connecting the cavity with an external air pump, a negative pressure can be formed in the smoke extraction channel, thereby timely extracting the smoke generated at the head position.

[0033] like Figure 1 - Figure 3 As shown, the radiofrequency surgical electrode with smoke suction function includes:

[0034] The handle 100 has a cavity formed inside;

[0035] The sheath tube 200 is disposed on one side of the handle 100 and communicated with the cavity;

[0036] The electrode tube 300 is disposed inside the sheath tube 200, and the electrode tube 300 includes a head 310 extending from the sheath tube 200 and a tail 320 extending into the cavity; and

[0037] The smoke extraction channel 400 is disposed inside the sheath tube 200 . The smoke extraction channel 400 is communicated with the cavity, and negative pressure is formed inside the smoke extraction channel 400 to extract smoke at the head 310 of the sheath tube 200 .

[0038] In the technical solution adopted in this embodiment, the radiofrequency surgical electrode with smoke suction function includes a handle 100, so that the doctor can easily hold the handle 100 for surgery, and a cavity is formed inside the handle 100; in order to protect the electrode tube 300 and prevent accidental injury to other tissues, a sheath tube 200 is also provided on one side of the handle 100; the electrode tube 300 is protected by being arranged inside the sheath tube 200, and the head 310 of the electrode tube 300 is extended from the outside of the sheath tube 200 to facilitate surgery, and the tail 320 of the electrode tube 300 is extended to the inside of the cavity to facilitate electrical connection with an external radiofrequency instrument. In addition, the head 310 of the electrode tube 300 will generate smoke during the operation. In order to prevent the smoke from interfering with the operation, a smoke extraction channel 400 is provided inside the sheath tube 200, and the smoke extraction channel 400 is connected with the cavity. By connecting the cavity with an external air pump, a negative pressure can be formed in the smoke extraction channel 400, so that the smoke generated at the head 310 position can be extracted in time. In this way, the doctor's field of vision can be ensured to be clear during the operation, which is conducive to improving the efficiency of the operation.

[0039] Specifically, the shape of the electrode tube 300 is not specifically limited, for example, it can be a curved knife, a ball-end knife or a triangular knife, as long as it can be electrically connected to an external radio frequency instrument and generate high-frequency energy at the head 310 of the electrode tube 300; similarly, the shape of the sheath tube 200 is not specifically limited, for example, it can be a straight tube type or a curved type, as long as the smoking channel 400 can be formed inside it and can cooperate with the electrode tube 300. It should be noted that the type of the smoking channel 400 is not specifically limited, for example, it can be a smoking tube 700 separately arranged inside the sheath tube 200, or it can be a smoking tube 700 formed inside the sheath tube 200, as long as it can form a smoke channel. The shape of the handle 100 is not specifically limited, for example, it can be a T-shaped or other shapes, as long as it has a cavity connected to the smoking channel 400 formed inside and is easy for the doctor to hold.

[0040] Alternatively, if Figure 2 and Figure 3As shown, in one embodiment of the utility model, a smoke extraction channel 400 is formed between the outer wall of the electrode tube 300 and the inner wall of the sheath tube 200, so that the smoke generated at the head 310 of the electrode tube 300 can be discharged through the smoke extraction channel 400. In this way, the doctor's field of vision can be kept clear during the operation, which facilitates more accurate positioning of the operation, thereby increasing the speed of the operation. Preferably, the smoke extraction channel 400 can extend from one end of the sheath tube 200 to the other end of the sheath tube 200.

[0041] Alternatively, if Figure 3 As shown, in one embodiment of the utility model, considering that the position of some lesion tissues is relatively special, the doctor needs to rotate the electrode tube 300 continuously during the operation, which prolongs the operation time and increases the pain of the patient. Therefore, the radio frequency surgical electrode with smoke suction function also includes a rotating sleeve 500. By rotating the rotating sleeve 500 and connecting it with the handle 100, and sleeved on the outer periphery of the sheath tube 200, the sheath tube 200 and the electrode tube 300 can be rotated by rotating the rotating sleeve 500, so as to adjust the position of the head 310 of the electrode tube 300. It should be noted that the shape of the rotating sleeve 500 is not specifically limited, for example, it can be a rotating ring, or a rotating tube. In other embodiments, in order to improve the connection strength between the rotating sleeve 500 and the handle 100, a first extension portion 510 is further provided on the rotating sleeve 500. By fixing the first extension portion 510 with the tail 320 of the electrode tube 300 and extending it into the cavity, the smoke in the smoke extraction channel 400 can be smoothly guided into the cavity, and then guided to the outside.

[0042] Alternatively, if Figure 1 and Figure 3 As shown, in another embodiment of the utility model, in order to facilitate the control of the rotating sleeve 500, the radio frequency surgical electrode with smoke suction function also includes a fixed shell 600, by arranging the fixed shell 600 on the side of the rotating sleeve 500 away from the handle 100, and the fixed shell 600 is fixedly connected to the sheath tube 200. Specifically, for the specific connection method between the fixed shell 600 and the rotating sleeve 500, for example, welding or riveting, etc., can also be made in one piece; by setting the fixed shell 600, the fixing strength of the rotating sleeve 500 to the sheath tube 200 can be improved.

[0043] Alternatively, if Figure 3 As shown, in one embodiment of the utility model, in order to improve the connection strength between the rotating sleeve 500 and the fixed shell 600, a second extension portion 520 is further provided on the rotating sleeve 500. By fixedly connecting the second extension portion 520 to the sheath tube 200 and extending it to the interior of the fixed shell 600, the sheath tube 200 and the electrode tube 300 can be smoothly driven to rotate together by rotating the rotating sleeve 500.

[0044] Alternatively, if Figure 1 and Figure 3 As shown, in one embodiment of the utility model, in order to facilitate the extraction of smoke in the smoking channel 400, the radiofrequency surgical electrode with smoke extraction function also includes a smoking tube 700. Preferably, the smoking tube 700 is arranged on the handle 100, and one end of the smoking tube 700 extends into the cavity to communicate with the smoking channel 400, and the other end extends to the outside of the handle 100 and is connected to the external negative pressure device. In this way, the smoke in the smoking channel 400 can be extracted in time.

[0045] Alternatively, if Figure 2 As shown, in one embodiment of the present invention, in order to broaden the surgical range, the head 310 of the electrode tube 300 can be set to an arc-shaped structure or a bent structure, so that the radiofrequency surgical electrode with smoke suction function can be applied to lesion tissues in various locations.

[0046] Alternatively, if Figure 1 and Figure 3 As shown, in one embodiment of the utility model, in order to provide the electrode tube 300 with the electrical energy required for the surgical process so that the head 310 of the electrode tube 300 can generate high-frequency energy, the radio frequency surgical electrode with smoke suction function also includes a cable 800, the cable 800 is arranged in the cavity, and one end of the cable 800 is connected to the electrode tube 300, and the other end extends to the outside of the handle 100 and is connected to an external radio frequency instrument. It should be pointed out that in order to timely extract the high-frequency energy generated at the electrode tube 300, the electrode tube 300 includes at least two first electrodes and a second electrode with opposite electrodes. It can be understood that at least two electrical conductors are provided in the cable 800, respectively connecting the first electrode and the second electrode of the electrode tube 300.

[0047] Optionally, in an embodiment of the utility model, since the cavity in the handle 100 is connected to the smoke extraction channel 400, part of the blood and residual tissue will be sucked out during the smoke extraction process. In order to prevent the extracted substances from corroding the cable 800, the radiofrequency surgical electrode with smoke extraction function also includes a protective cover, and the protective cover is fixedly mounted on the outer periphery of the cable 800 to protect the cable 800 from corrosion. It should be pointed out that the material of the protective cover is not specifically limited, for example, it can be rubber, or it can be a material with anti-corrosion properties such as phenolic resin or polytetrafluoroethylene.

[0048] The above description is only an optional embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
