[0021] like Figure 1 As shown, a self-cleaning radio frequency blade head comprises a handle 1, a pipeline assembly 2 connected to the front end of the handle 1, and a blade head assembly 3 installed at the front end of the pipeline assembly 2, an outer tube 4 rotating around the front end of the blade head assembly 3 is installed at the front end of the blade head assembly 3, and a rotating cleaning member is installed inside the outer tube 4, and the cleaning member is driven to rotate by the rotation of the outer tube 4 to complete the cleaning of the front end of the blade head assembly 3;

[0022] The outer tube 4 is provided with an adjustment ring 41 on one side close to the handle to assist in promoting the outer tube to rotate.

[0023] In some embodiments of the present invention, Figure 2-5 As shown, the radio frequency blade head includes a handle 1, a pipeline assembly 2 connected to the front end of the handle 1, and a blade head assembly 3 installed at the front end of the pipeline assembly 2, an outer tube 4 rotating around the front end of the blade head assembly 3 is installed at the front end of the blade head assembly 3, a rotating cleaning member is installed inside the outer tube 4, a protective tube 5 is sleeved on the outside of the pipeline assembly 2 and the inner tube, a channel 6 is left between the protective tube 5 and the pipeline assembly 2 and the outer tube 4, and a connecting member driving the outer tube 4 to rotate at the front end of the blade head assembly 3 is installed in the channel 6;

[0024] Furthermore, a driving component connected to the connecting piece is installed inside the handle 1 to provide power support for the rotation of the connecting piece and the appearance. The driving component can be a micro rotor motor, a micro linear motor or other components that can provide rotational power support.

[0025] The cutter head assembly 3 includes an electrode seat 7 located at the front end of the pipeline assembly 2, a cleaning channel 8 is provided in the middle of the electrode seat 7, an electrode sheet 9 is installed on the front end surface of the electrode seat 7, and the electrode sheet 9 includes a plurality of outer ends 25 extending outwards, and a through hole is provided on the outer end 25;

[0026] The pipeline assembly 2 includes a heat shrink tube 10, a stainless steel tube 11, a waterway protection tube 12 and a waterway pipe 13 which are sequentially sleeved from the inside to the outside. The front end of the waterway pipe 13 is plugged into the bottom end of the cleaning channel 8. A gap is left between the waterway pipe 13 and the waterway protection tube 12. A plurality of electrode wires 14 extending along the direction of the waterway pipe 13 are arranged in the gap.

[0027] The inner and outer multi-layer pipes are arranged in sequence, which can provide effective protection for the internal electrode wire 14 and the water pipe 13, ensure the structural strength of the pipe assembly 2, and make it difficult to bend during actual application, thereby ensuring the effective implementation of the operation. The cleaning channel 8 inside the electrode holder 7 is connected to the water pipe 13, and the water pipe 13 is used to transport water to the electrode holder 7 and the front end blade component to flush and clean the diseased tissue.

[0028] The front end of the electrode wire 14 passes through the electrode holder 7 and extends into the through hole of the outer end 25 of the electrode sheet 9 . A ball head 15 is installed at the front end of the electrode wire 14 , and the ball head 15 is clamped on the front side of the electrode sheet 9 .

[0029] Furthermore, part of the electrode wire 14 extends along the direction of the water pipe 13 to the front end of the electrode holder 7, and multiple outer ends 25 cooperate with several electrode wires 14. A ball head 15 is arranged at the front end to be clamped on the outer end 25 of the electrode sheet 9, which can provide a certain limiting effect for the installation of the electrode holder 7 at the front end of the pipeline assembly 2 to prevent it from falling off at the front end of the pipeline assembly 2.

[0030] The outer tube 4 is sleeved on the outside of the front end of the electrode seat 7, and a bearing ring 16 sleeved on the outside of the electrode seat 7 is provided at the rear end of the outer tube 4. The outer tube 4 rotates outside the electrode seat 7 through the bearing ring 16, and a circle of gear ring 17 is installed on the outer wall of the outer tube 4.

[0031] The front end of the protective tube 5 is sleeved on the outside of the front end of the outer tube 4, and a sealing ring 18 is sleeved at the connection between the front end of the protective tube 5 and the front end of the outer tube 4. The sealing ring 18 seals the gap between the rotating outer surface and the front end of the protective tube 5 to prevent the patient's body fluids or water in the cleaning channel 8 from entering the protective tube 5 during the operation.

[0032] The connecting part includes a transmission shaft 19 extending in the channel 6. A gear 20 meshing with the gear ring 17 is installed at one end of the transmission shaft 19 close to the outer tube 4.

[0033] During actual use, the electrode wire 14 is partially energized, and the ball head 15 is located at the front end to increase the contact area with the patient's tissue. The radio frequency current generates heat energy to cut or coagulate the diseased tissue. In this process, the diseased tissue will adhere to the electrode sheet 9 and the ball head 15. The driving component in the handle 1 drives the transmission shaft 19 to rotate in the bearing 21, so that the gear 20 at the front end of the transmission shaft 19 engages with the gear ring 17 on the outer tube 4, driving the outer tube 4 to rotate, thereby rotating the cleaning part on the inner side of the outer tube 4 to clean the adhered diseased tissue, and the water flowing out of the cleaning channel 8 inside the electrode holder 7 will flush away the cleaned diseased tissue, completing the cleaning of the blade part.

[0034] The cleaning member includes a cleaning rod 23 fixed on the inner wall of the outer tube 4 , the end of the cleaning rod 23 extends to the middle of the electrode sheet 9 and fits the surface of the electrode sheet 9 , and a curved scraping portion 24 is provided in the middle of the cleaning rod 23 .

[0035] Furthermore, during the rotation and cleaning process of the cleaning piece, the curved part of the cleaning rod 23 scrapes the surface of the ball head 15, and the straight part scrapes the surface of the electrode sheet 9, which, together with the water flowing out of the cleaning channel 8, can effectively complete the removal of part of the diseased tissue of the cutter head assembly 3.
