After the pushing device 2 is inserted into the limiting device 3, when the ejection protruding block 331 is aligned to the limiting groove 23, the ejection protruding block 331 is ejected into the inserting groove 252 and the limiting groove 23 under the action of the ejection spring 332, and then the pushing device 2 is locked;
S5 unlocking
After the pushing force is stopped to be applied to the pushing device 2, the sliding tube 251 rebounds under the action of the return spring 241, and the ejection inclined block 26 ejects the ejection convex block 331 from the insertion groove 252 and the limit groove 23;
s6 needle pulling and rebinding
After the needle of the injector 1 is pulled out from the patient, the needle of the injector 1 is inserted into another point;
s7 multipoint injection
And repeating the steps S3, S4, S5 and S6, and sequentially performing multi-point distributed low-dose injection until the point injection of all the anesthetic areas is completed.
As shown in fig. 2 and 3, in some embodiments, in the unlocking step, when the pushing force applied by the pushing device 2 is withdrawn, the pushing device 2 and the limiting device 3 are automatically unlocked, so as to realize rapid continuous distributed low-dose quantitative injection of the point of the anesthetic region.
By withdrawing the thrust borne by the pushing device 2, the pushing device 2 and the limiting device 3 are unlocked, the next point can be injected, meanwhile, the pushing device 2 and the limiting device 3 are unlocked without redundant operation, the rapid continuous distributed low-dose quantitative injection of the anesthetic in the anesthetic region is conveniently realized, the uneven concentration of the anesthetic at the sequential injection point is avoided, the anesthetic effect is greatly reduced, the pain of a patient in the operation process is reduced, meanwhile, the concentration of a part of the region is too high, and side effects are easy to cause.
