The handle 1 is provided with a power part 24 for driving the gear 21 to rotate, the power part 24 can be set as the handle 1 or an adjusting cap, the power part 24 is coaxially fixed with the gear 21, the power part 24 is rotatably connected with the handle 1, one end of the power part is positioned outside the handle 1, when the handle 1 drives the gear 21 to rotate clockwise, the sliding rack 19 is driven to move towards the direction away from the convex lens 16, the moving rack 20 is driven to move towards the convex lens 16, and the moving direction of the luminous part 17 is opposite to the moving direction of the blowing part 4; the moving distance of the sliding rack 19 and the moving rack 20 is not more than the focal distance of the convex lens 16, in this embodiment, the moving distance of the sliding rack 19 and the moving rack 20 is further realized by limiting the size of the sliding sleeve, and the moving distance is maximally equal to the focal distance, so when the light-emitting member 17 moves to the focal position, the light-emitting member 17 realizes the focusing effect.
Because the operation position is unchangeable, if the electrotome pen is located when keeping away from the operation position this moment, stretch into the illuminating effect of process in order to guarantee to the electrotome pen this moment, control illuminating part 17 and move towards convex lens 16 direction this moment, the light that illuminating part 17 sent at this moment is dispersed through convex lens 16, enlarge irradiant scope, the staff of being convenient for stretches into the electrotome pen to the operation position, it follows slide bar 7 towards handle 1 internal motion to blow 4 this moment, contained angle grow between 4 and the slide bar 7 of blowing this moment, the refraction light of 4 and convex lens 16 of blowing this moment mutually supports, and then avoid blowing 4 slope to influence the light of refraction.
Similarly, when the surgical site needs to be focused and irradiated, smoke is generated when the surgical site starts to operate, so that the surgical site needs to be focused, the protection requirement on the convex lens 16 is highest, smoke needs to be isolated from the convex lens 16, and even the smoke needs to be purified or extracted when the smoke is excessive; at the moment, the light-emitting piece 17 is controlled to move towards the direction far away from the convex lens 16, the angle of the light refracted by the convex lens 16 is reduced, the focusing effect of the light is realized, when the light-emitting piece 17 moves to the focal position of the convex lens 16, the focusing irradiation effect of the operation position is realized, meanwhile, the distance to which the air-blowing piece 4 moves is also the largest, the included angle between the air-blowing piece 4 and the sliding rod 7 is the smallest, and the effect that the air-blowing piece 4 influences the refracted light is also realized; through the cooperation of blowing piece 4 and illuminating part 17, realize reducing the refraction light and the effect of the mutual noninterference probability of blowing piece 4.
The implementation principle of the ablation electrode with the illumination function in the embodiment of the application is as follows: when a main scalpel doctor extends the electric scalpel pen into a surgical position, the twisting power piece 24 rotates towards the anticlockwise direction, the sliding rack 19 moves towards the outlet 5, the moving rack 20 moves towards the convex lens 16, the luminous piece 17 is close to the convex lens 16, the irradiation range of the luminous piece 17 is large, the main scalpel doctor can operate conveniently, and the air blowing piece 4 moves towards the inside of the handle 1; when the electrotome pen moves to the operation position, the control light-emitting part 17 moves towards the direction far away from the convex lens 16, the light-emitting part 17 focuses on the operation position and covers and establishes, the irradiation precision is improved, and the success rate of the operation position cutting operation is improved.
Meanwhile, after the smoke is generated, whether the smoke is excessive is judged, if the smoke is not excessive but the sight line is blocked, the air blowing port 6 on the air blowing piece 4 is blown through the output pipe 10 by pressing the pressurizing ball 9, an air curtain is formed outside the convex lens 16 and used for isolating and evacuating the smoke; if the smog is too much, the smog is connected with the smoke extraction pipe 13 and the input pipe 11 through the three-way valve 15, the smog is purified through the filter piece 14 and is discharged from the output pipe 10 after being mixed with the outside air, the smog can be extracted at the moment, an air curtain is formed on the outer wall of the convex lens 16 as usual, and the smog is prevented from influencing the lighting effect of the light-emitting piece 17 in the operation process.
The above embodiments are preferred embodiments of the present application, and the protection scope of the present application is not limited by the above embodiments, so: all equivalent changes made according to the structure, shape and principle of the present application shall be covered by the protection scope of the present application.
