Such blockage should be completely reversible and cause no tissue damage. Compared with general anesthesia, local anesthesia has unique advantages in some aspects. First, local anesthesia has no effect on consciousness; second, local anesthesia can also play a certain role in postoperative analgesia; in addition, local anesthesia has the advantages of simple operation, safety, fewer complications, little effect on physiological function, blocking of various adverse nerve reactions, reduction of stress reaction caused by surgical trauma and rapid recovery. Common local anesthesia includes four types of surface anesthesia, local infiltration anesthesia, regional block and nerve conduction block.

[0003] Among them, surface anesthesia generally adopts a spray anesthesia method, that is, anesthetic is sprayed in the form of aerosol to the surface of the part to be anesthetized through a spray device.

However, the manual extrusion method cannot continuously spray the liquid, which may cause too fast or uneven use of the liquid, which is easy to induce hypotension. The high-pressure pump spraying method has the problem of low atomization efficiency, which may spray the liquid that has not been atomized, resulting in too much or too little local anesthetic, affecting the anesthesia effect.

[0028] Embodiment 2

[0029] Further, on the basis of embodiment 1, the crank slider mechanism comprises a cross-shaped sliding frame 7, vertical sliding grooves 8 and horizontal sliding grooves 9 are arranged on the sliding frame 7 and cross in the middle, and a mounting plate 10 is arranged on one side of the sliding frame 7, a drive shaft 11 perpendicular to the mounting plate 10 is rotatably arranged on the mounting plate 10, the drive shaft 11 is driven by a drive motor 12 fixed on the mounting plate 10, a first crank 13 is hinged to the other end of the drive shaft 11, a second crank 14 is hinged to the other end of the first crank 13, the first crank 13 and the second crank 14 are hinged in the middle, first and second sliding blocks 15 and 17 are hinged to the two ends of the second crank 14 respectively, the first sliding block 15 can freely slide along the horizontal sliding groove 9, a first push rod 16 is further connected to the first sliding block 15, the first push rod 16 passes through the sliding frame 7 and the outer cylinder 1 in sequence and is connected to one end of the sealing block 4, the second sliding block 17 can freely slide along the vertical sliding groove 8, a second push rod 18 is further connected to the second sliding block 17, the second push rod 18 passes through the sliding frame 7 and the atomization cylinder 5 in sequence and is connected to the piston sheet 6.

[0030] Embodiment 3

[0031] Further, on the basis of embodiment 2, as Figure 4As shown, the plugging block 4 comprises a first section 21 located in the first groove, a second section 22 with the same outer diameter as the anesthetic tube 2, and a third section 23 located in the first groove, the sum of the lengths of the first section 21 and the second section 22 is the same as the length of the transverse sliding groove 9, the third section 23 is provided with a circular mounting groove, the circular mounting groove is provided with a first fogging disc 24, the bottom of the first fogging disc 24 is provided with a groove, the groove is provided with a fogging motor 25, the output shaft of the fogging motor 25 is vertically downward and is provided with a second fogging disc 26, a plurality of fogging holes are arranged on the first fogging disc 24 and the second fogging disc 26 in a staggered manner.
