[0025] It should be noted that after the user inserts the positioning knife rod 4 into the positioning sleeve 1, by rotating the locking sleeve 3 several times, the movable plate 54 can be squeezed to move toward the rear side of the inner cavity of the positioning sleeve 1. Since the movable plate 54 is provided with an oblique arc groove 541, under the lateral constraint of the extension groove 51 on the limit plate 52, the positioning rod 55 will drive the limit plate 52 to engage into the stepped groove 41 of the positioning knife rod 4. At this time, the entire device can realize the locking installation of the positioning knife rod 4. At this time, the limit member 62 just engages into the rear side wall of the positioning knife rod 4. Afterwards, the user starts the driving motor 61 through the controller to drive the limit member 62 to rotate the positioning knife rod 4, which can make the knife head 7 turn, so as to facilitate the doctor to quickly swing the knife in a narrow area, thereby accelerating the effect of surgical treatment on the patient.

A maintenance cap 21 is detachably installed on the rear side wall of the positioning handle 2, and a storage power supply is fixedly installed on the inner side wall of the maintenance cap 21. A controller is also fixedly installed on the side wall of the support plate 6, and a sealing rubber ring 31 is provided at the connection between the locking sleeve 3 and the side wall of the positioning sleeve 1, and a sealing rubber ring is movably installed on the inner side wall of the bearing sleeve 11. A corrugated anti-slip sleeve 22 is fixedly installed on the outer wall of the positioning handle 2, and the inner cavity of the positioning handle 2 is hollow. A water inlet pipe 23 is fixedly installed on the side wall of the maintenance cap 21, and a water outlet hole 42 is provided on the side wall of the positioning knife rod 4 close to the cutter head 7.

[0027] It should be noted that before the doctor performs the scalpel surgery on the patient, the water inlet pipe 23 is connected to the external anesthesia instrument, and then the anesthetic can be input into the water inlet pipe 23 through the pump body. At this time, since the inner cavity of the positioning handle 2 is hollow, a sealing rubber ring 31 is provided at the connection between the locking sleeve 3 and the side wall of the positioning sleeve 1, and a sealing rubber ring is movably installed on the inner wall of the bearing sleeve 11 to ensure that the inner cavity of the positioning handle 2 is in a sealed state. With the continuous pressurization of the external pump body, the anesthetic can be discharged through the water outlet hole 42 on the positioning knife rod 4, and quickly contact the part requiring surgery, which is targeted to reduce the pain experience of subsequent patients during the operation. Furthermore, the steering mechanism 9 includes a connecting seat 91 fixedly mounted on the side wall of the positioning sleeve 1, and a steering motor 92 fixedly mounted on the side wall of the connecting seat 91 through a frame, a driving gear 93 is fixedly mounted on the output shaft end of the steering motor 92, a ring gear plate 94 is fixedly mounted on the side wall of the rotating disk 8, the driving gear 93 is meshedly connected with the ring gear plate 94, a rotating groove 12 is opened on the side wall of the positioning sleeve 1, the rotating disk 8 slides in the inner cavity of the rotating groove 12, an auxiliary cylinder 81 is fixedly mounted on the side wall of the rotating disk 8, and an air inlet 81 is opened on the upper part of the side wall of the auxiliary cylinder 81 1.

[0028] It should be noted that when the doctor performs a scalpel operation on the patient, the steering motor 92 is started to rotate the driving gear 93. Since the driving gear 93 is meshed and connected with the ring gear plate 94, and the ring gear plate 94 is fixedly connected with the rotating disk 8, under the restraining effect of the rotating groove 12 on the rotating disk 8, the driving gear 93 will drive the ring gear plate 94 to rotate the rotating disk 8 continuously, so that the position of the auxiliary cylinder 81 on the rotating disk 8 is constantly changed, and the guide fan 83 inside the auxiliary cylinder 81 is synchronously started, so that the outside air can enter the interior of the auxiliary cylinder 81 through the air inlet 811, and then from the hollow cylinder cover 84. Blowing out, since there are a large number of mint particles in the hollow tube cover 84, the wind blown out from the hollow tube cover 84 will have a cool feeling of mint. At this time, blowing on the patient's surgical site can reduce the patient's pain experience during the operation, thereby effectively improving the doctor's operation efficiency and success rate. Since the rotating disk 8 drives the auxiliary tube 81 to rotate continuously, cool wind with a larger area can be blown out, improving the practicality of the entire device. At the same time, with the continuous displacement of the auxiliary tube 81 and the cooperation of the connecting spring 86, the mint particles in the hollow tube cover 84 can be fully mixed to ensure that the cool wind blown out always has a good analgesic effect.

[0029] Working principle: After the user inserts the positioning knife rod 4 into the positioning sleeve 1, the user can squeeze the movable plate 54 to move to the rear side of the inner cavity of the positioning sleeve 1 by rotating the locking sleeve 3 for several circles. Since the movable plate 54 is provided with an oblique arc groove 541, under the lateral constraint of the extension groove 51 on the limit plate 52, the positioning rod 55 will drive the limit plate 52 to snap into the stepped groove 41 of the positioning knife rod 4. At this time, the entire device can realize the locking installation of the positioning knife rod 4. At this time, the limit member 62 just snaps into the rear side wall of the positioning knife rod 4. Afterwards, the user starts the driving motor 61 through the controller to drive the limit member 62 to rotate the positioning knife rod 4, which can make the knife head 7 turn, so as to facilitate the doctor to quickly swing the knife in a narrow area, thereby accelerating the effect of surgical treatment on the patient; Before the doctor performs a scalpel operation on the patient, the water inlet pipe 23 is connected to the external anesthesia instrument, and then the anesthetic can be input into the water inlet pipe 23 through the pump body. At this time, since the inner cavity of the positioning handle 2 is hollow, a sealing rubber ring 31 is provided at the connection between the locking sleeve 3 and the side wall of the positioning sleeve 1, and a sealing rubber ring is movably installed on the inner wall of the bearing sleeve 11 to ensure that the inner cavity of the positioning handle 2 is in a sealed state. With the continuous pressurization of the external pump body, the anesthetic can be discharged through the water outlet hole 42 on the positioning knife rod 4, and quickly contact the part that needs surgery, which is targeted to reduce the pain experience of subsequent patients during the operation; When the doctor performs a knife-swinging operation on the patient, the steering motor 92 is started to rotate the driving gear 93. Since the driving gear 93 is meshed and connected with the ring gear plate 94, and the ring gear plate 94 is fixedly connected with the rotating disk 8, under the restraining effect of the rotating groove 12 on the rotating disk 8, the driving gear 93 will drive the ring gear plate 94 to rotate the rotating disk 8 continuously, so that the position of the auxiliary cylinder 81 on the rotating disk 8 is constantly changed, and the guide fan 83 inside the auxiliary cylinder 81 is synchronously started, so that the outside air can enter the interior of the auxiliary cylinder 81 through the air inlet 811, and then blown out from the hollow cylinder cover 84. There are a large number of mint particles in the hollow tube cover 84. At this time, the wind blown out from the hollow tube cover 84 will have a cool feeling of mint. At this time, it will blow on the patient's surgical site, which can reduce the patient's pain experience during the operation, and thus effectively improve the doctor's operation efficiency and success rate. Since the rotating disk 8 drives the auxiliary tube 81 to rotate continuously, it can blow out cool wind with a larger area, improving the practicality of the entire device. At the same time, with the continuous displacement of the auxiliary tube 81 and the cooperation of the connecting spring 86, the mint particles in the hollow tube cover 84 can be fully mixed to ensure that the blown cool wind always has a good analgesic effect.
