Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0031] Please refer to Figures 1 - 5 , the present invention provides a technical solution: a mist-blowing device that can be adjusted with one hand, one end of the holding part 2 is connected to the mist-blowing pipe 1, the other end of the holding part 2 is connected to the connecting seat 4, an air supply pipe 6 and a water supply pipe 5 are arranged on the connecting seat 4, a central pipe 8 is arranged in the holding part 2, one end of the central pipe 8 is connected to the water supply pipe 5, and the other end thereof is connected to the mist-blowing pipe 1, one end of the water supply pipe 5 is connected to the water delivery pipe 9, the water delivery pipe 9 is connected to the connecting head 10, the connecting head 10 is arranged in the middle of the central pipe 8, and a quantitative control mechanism 3 for adjusting the water delivery amount is further arranged on one side of the connecting head 10;

[0032] The quantitative control mechanism 3 includes a valve plate 309 arranged perpendicular to the end of the water delivery pipe 9. The valve plate 309 is movably arranged in the valve seat 301. The valve seat 301 is arranged on the side of the central pipe 8. A ball screw 310 is also arranged in the valve seat 301. A nut seat 311 is arranged on the ball screw 310. The nut seat 311 is connected to the valve plate 309. An adjustment port 304 is arranged on the side of the holding part 2. An adjustment knob 303 is rotatably arranged in the adjustment port 304. When holding the holding part 2 with one hand, the adjustment knob 303 can be toggled by the thumb, which is convenient for the operator to perform single-handed operation. The adjustment knob 303 is connected to the ball screw 310 through a transmission structure; the transmission structure includes a support rod 305. The support rod 305 is arranged in the middle of the adjustment knob 303. The support rod 305 is rotatably arranged in the support frame 312. The support frame 312 is arranged on one side of the inner wall of the holding part 2. A worm 306 is also arranged on one side of the support rod 305. The worm 306 meshes with the worm gear 307. The worm gear 307 is rotatably arranged on one side of the connecting shaft 302. The connecting shaft 302 is rotatably arranged on one side inside the holding part 2. Through the transmission of the worm 306 and the worm gear 307, when toggling the adjustment knob 303, the connecting shaft 302 can be driven to rotate.

[0033] During use, the gas supply pipe 6 can be connected to the carbon dioxide input pipe, and the water supply pipe 5 can be connected to the saline input pipe. The operator holds the holding part 2, and then according to the intraoperative needs, uses the thumb to toggle the adjustment knob 303. The adjustment knob 303 drives the support rod 305 to rotate. The support rod 305 drives the worm 306 to rotate. The rotation of the worm 306 drives the worm gear 307 to rotate. The rotation of the worm gear 307 drives the connecting shaft 302 to rotate. The connecting shaft 302 drives the ball screw 310 to rotate. The rotation of the ball screw 310 drives the nut seat 311 to linearly move. The movement of the nut seat 311 drives the valve plate 309 to move. The movement of the valve plate 309 then opens the interface of the water delivery pipe 9. At this time, the saline is transported to the water delivery pipe 9. The water delivery pipe 9 transports the saline to the central pipe 8. The gas delivery pipe transports high-pressure carbon dioxide gas to the central pipe 8, and then blows it out as high-pressure humid gas through the atomizing pipe 1 and blows away the blood, and at the same time can ensure the tissue is moist. By toggling the adjustment knob 303 in real time, the moving position of the valve plate 309 can be controlled, and then the opening size of the interface of the water delivery pipe 9 can be controlled, and the saline output can be controlled, and the humidity of the tissue can be adjusted in real time according to the needs.

[0034] Further, a coupling is arranged at one end of the connecting shaft 302. One end of the coupling is connected to the ball screw 310. Through the connection of the coupling, the stability of the ball screw 310 during rotation can be improved.

[0035] Further, an inverted L-shaped bracket 308 is also arranged at one end of the nut seat 311. One end of the bracket 308 is connected to the valve plate 309, which can increase the moving stroke of the valve plate 309, and then can quickly control the opening and closing of the interface of the delivery pipe.

[0036] Furthermore, a guiding slider is also arranged on the other side of the lead screw seat 311. The guiding slider is slidably arranged in a guiding chute, and the guiding chute is arranged on one surface of the cross frame. The cross frame is arranged on one side inside the valve seat 301. When the lead screw seat 311 moves, it drives the guiding slider to move in the guiding chute, improving the stability of the lead screw seat 311 during movement.

[0037] Furthermore, a quick connector 7 is arranged at one end of the air supply pipe 6, which can quickly connect the air supply pipe 6 with the carbon dioxide input pipe.

[0038] Please refer to Figures 6 - 8 , and a quick adjustment mechanism is also arranged on one side of the holding part 2. The quick adjustment mechanism includes a ratchet wheel 314. One end of the support rod 305 is provided with the ratchet wheel 314. A clamping component for automatically positioning the ratchet wheel 314 is arranged on one side of the ratchet wheel 314. A torsion spring 313 is also sleeved on the other side of the support rod 305. One end of the torsion spring 313 is connected to the support rod 305, and the other end of the torsion spring 313 is connected to the support frame 312. Through the elastic force of the torsion spring 313, the support rod 305 can be driven to quickly rotate. At the same time, through the clamping component, the rotation position of the ratchet wheel 314 can be locked, and then the moving position of the valve plate 309 can be locked to control the output volume of the brine.

[0039] The clamping component includes a clamping block 315 corresponding to the teeth of the ratchet wheel 314. The clamping block 315 is arranged at one end of the adjusting rod 318. The adjusting rod 318 is movably arranged in the guiding port 316. The guiding port 316 is arranged on one side of the holding part 2. The guiding port 316 and the adjusting port 304 are arranged horizontally, which can guide the movement of the clamping block 315. A return spring 317 is also sleeved on the adjusting rod 318. One end of the return spring 317 is connected to the adjusting rod 318, and the other end of the return spring 317 is connected to the guiding port 316, which can drive the adjusting rod 318 to move back to its original position, and then fix the clamping block 315 in the corresponding teeth of the ratchet wheel 314.

[0040] When the adjusting knob 303 rotates, the support rod 305 drives the torsion spring 313 to rotate, and at the same time drives the ratchet wheel 314 to rotate. When the ratchet wheel 314 rotates, it drives the clamping block 315 to move. The movement of the clamping block 315 drives the adjusting rod 318 to move in the adjusting port 304. The movement of the adjusting rod 318 compresses the return spring 317. When the opening size at the interface of the water delivery pipe 9 is adjusted, the return spring 317 drives the adjusting rod 318 to move back to its original position, and the clamping block 315 is snapped into the corresponding teeth of the ratchet wheel 314. The clamping block 315 fixes the ratchet wheel 314, and the ratchet wheel 314 fixes the support rod 305. At this time, the adjusting knob 303 is in a fixed state, and then the valve plate 309 can be positioned, ensuring the quantitative delivery of the brine.

[0041] The other end of the adjusting rod 318 is provided with an adjusting buckle 319. The distance between the adjusting buckle 319 and the holding part 2 is 1-2 cm, which is convenient for the operator's thumb to be inserted into the gap and trigger the adjusting buckle 319. When the saline is not needed, the thumb is inserted into the gap between the adjusting buckle 319 and the holding part 2, and then the adjusting buckle 319 is pushed upward. The adjusting buckle 319 drives the guide rod to move, the guide rod drives the clamping block 315 to move, so that the clamping block 315 is separated from the ratchet wheel 314. The torsion spring 313 drives the support rod 305 to rotate back to its original position, the support rod 305 drives the worm 306 to rotate back to its original position, the worm gear 307 drives the connecting shaft 302 to rotate back to its original position, and then the ball screw 310 rotates back to its original position. The ball screw 310 rotates back to its original position and drives the nut seat 311 to move back to its original position. The nut seat 311 drives the valve plate 309 to move back to its original position through the bracket 308. Furthermore, the valve plate 309 seals the interface of the water delivery pipe 9, realizing one-key quick sealing of the water delivery pipe 9, ensuring the dryness of the operating table and at the same time ensuring the environmental sterility.
