[0034] As a technical optimization of this utility model, the radiofrequency ablation mechanism 1 can be set to act more precisely on the target tissue, reduce damage to the surrounding normal tissue, thereby shortening the operation time and improving the success rate of the operation.

[0035] refer to Figure 6 The purification box 22 has grooves 4 on both sides of its inner cavity, and the outer side of the slide plate 35 is slidably connected to the inside of the grooves 4.

[0036] As a technical optimization of this utility model, the sliding groove 4 enables the sliding plate 35 to slide more smoothly inside the purification box 22, reducing friction between the two, extending the service life of the sliding plate 35, and at the same time limiting the sliding plate 35.

[0041] The working principle and usage process of this utility model are as follows: First, the user starts the turbine 25. The output end of the turbine 25 draws the smoke generated during surgery into the lower pipe 26 through the top cover 27 and the smoke extraction pipe 28. The input end of the turbine 25 discharges the smoke inside the lower pipe 26 into the filter cotton plate seat 29 inside the purification box 22, so that the filter cotton plate seat 29 filters and purifies the smoke. Then, the filtered and purified gas is discharged through the exhaust groove 210. When it is necessary to replace the filter cotton plate seat 29, pull the filter cotton plate seat 29 upward. The filter cotton plate seat 29 drives the fixing block 31 and the first protrusion block 32 to move upward. The first protrusion block 32 squeezes the second protrusion block 33 outward. The second protrusion block 33, together with the return spring 36 and the moving plate 34, retracts outward until the filter cotton plate seat 29 is removed. Then, the return spring 36 springs back inward. Then, the new filter cotton plate seat 29 is pressed in, so as to achieve the effect of smoke extraction and purification.

[0042] In summary, this radiofrequency electrosurgical unit that can extract smoke eliminates the problem of smoke generated during traditional use. By employing a turbine 25, the smoke is drawn into the purification box 22 through the top cover 27 and the smoke extraction tube 28. This prevents the smoke from obstructing the surgeon's view, being inhaled by the patient, increasing the risk to the patient during surgery, or affecting the quality of the surgery.
