[0002] With the development of medical technology and the improvement of medical level, the application of high-frequency electrosurgical unit in clinical practice has undergone many changes. High-frequency electrosurgical unit is an electrosurgical instrument that replaces mechanical scalpel for tissue cutting. It heats the tissue when it contacts the body through the high-frequency and high-voltage current generated by the effective electrode tip, thereby achieving the purpose of cutting and hemostasis.

[0003] However, when the existing high-frequency electric knife is used, it will heat the tissue and thus produce obvious smoke accompanied by a serious burnt smell, which will not only affect the doctor's surgical vision, but also make the medical staff in the operating room feel uncomfortable. In the prior art, when the doctor uses the high-frequency electric knife, an operating room nurse or assistant is required to hold a smoking pipe near the blade to absorb the smoke, which is not only very troublesome to operate, but also can only absorb on one side of the blade, and can only absorb a small amount of smoke. Moreover, since two people are operating, it is difficult to synchronize the movements, and the smoke cannot be absorbed in time, so the smoke absorption effect is not good. Utility Model Content

[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a high-efficiency surgical radio frequency knife smoke extraction device, which effectively solves the problems mentioned in the above background technology.

[0006] The smoking component includes a cylinder, a thin-walled cavity, filter cotton, a trumpet mouth, anti-skid patterns, a smoking tube, a fixing part, an external thread, an internal thread, a fixing block, a tube hole, an elastic card and a notch. The cylinder is screwed onto the radio frequency knife. A thin-walled cavity is provided in the thin wall of the cylinder. Anti-skid patterns are provided on the outer surface of the cylinder. A smoking tube connected to the thin-walled cavity is connected to one end of the cylinder. The smoking tube is provided with a fixing part that is clamped onto the radio frequency knife. The fixing part includes a fixing block, a tube hole, an elastic card and a notch. A tube hole is provided in the middle of the fixing block. An elastic card is provided on one side of the fixing block. A notch is provided on the elastic card.

[0007] Preferably, the interior of the thin-wall cavity is filled with filter cotton.

[0008] Preferably, the notch is smaller than half of the circumference of the elastic card.

[0009] Preferably, a bell mouth is provided at one end of the cylinder.

[0010] Preferably, the radio frequency knife is provided with an external thread, and the cylinder is provided with an internal thread near the end.

[0011] Preferably, the smoking tube is inserted into the tube hole.

[0012] Beneficial effect: When the utility model is used, the cylinder is screwed onto the radio frequency knife. After the screwing is completed, the elastic card on the fixed block on the smoking tube is clamped onto the radio frequency knife. When clamped, the notch on the elastic card is clamped onto the radio frequency knife, so the smoking tube can be fixed. One end of the smoking tube is connected to the external negative pressure fan, so that the installation of the smoking assembly can be completed. When in use, the smoking tube draws air from the thin-walled cavity of the cylinder, and the smoke generated when the radio frequency knife is used can be extracted through the trumpet mouth. The operation is simple and convenient. When not in use, the elastic card is removed from the radio frequency knife, and the cylinder can be removed by rotating it, which is convenient for the installation, use, and disassembly and storage of the smoking assembly. The utility model has a novel structure and an ingenious conception. It is convenient for extracting the smoke generated when the radio frequency knife is used, and is convenient for the installation, use, and disassembly and storage of the smoking assembly, which is convenient for use.
