Description

Technical Field

[0001] The utility model relates to the technical field of electric knife pens, in particular to a high-frequency electric knife pen capable of smoking. Background Art

[0002] The electric pen knife is an electrosurgical instrument that replaces mechanical scalpels for tissue cutting. It heats the tissue when it comes into contact with the body through the high-frequency and high-voltage current generated by the effective electrode tip, achieving the purpose of cutting and hemostasis by separating and coagulating the body tissue.

[0003] When doctors operate, smoke will be generated, which will block the doctor's vision. After searching, it was found that the Chinese utility model patent with the authorization publication number CN219579015U discloses a smoking electric knife pen. From its specification, it can be known that when the surgical position is changed, the electrode blade of the electric knife pen is retracted or replaced to adjust the length to adapt to the surgery. At this time, the position of the smoking pipe can be adjusted by the regulator. When the worm in the regulator rotates, the smoking pipe moves along the length direction of the installation chamber due to meshing, and reaches the appropriate position for smoke exhaust, ensuring the smoking efficiency without affecting the surgical operation.

[0004] However, the above-mentioned electrosurgical pen has the following problems: (1) The smoking device is installed on the electrosurgical pen together with the regulator and cannot be disassembled, which is inconvenient for maintenance and cannot be installed as an option; (2) Although the distance of the smoking tube is adjustable, its angle cannot be adjusted, that is, the angle of the smoking tube cannot be adjusted according to the surgical situation, resulting in a small smoking range.
