Description
Technical field
This utility model relates to a kind of quantitatively anesthetic needle.
Background technology
When performing the operation, need to beat anesthetic needle at operative segment, anesthetic needle of the prior art cannot complete narcotic quantitative conveying, when therefore needing again to input in operation process, need assistant again to extract anesthetis, then carry out inputting again extremely bothering, narcotic input quantity of the prior art relies on eye observation simultaneously, therefore can produce error unavoidably, inputted at least in operation process patient can produce pain, inputted and patient can be caused at most numb for a long time.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of quantitatively anesthetic needle, this device once can be loaded and repeatedly input, and the amount of each input can control according to use needs, avoids anesthetis to input excessive or very few, while satisfied operation needs, reduce the injury to patient.
For solving the problem, this utility model adopts following technical scheme:
A kind of quantitatively anesthetic needle, comprise the syringe loading anesthetis, and be engaged in the piston head of described syringe inside, and connect the columniform piston rod of described piston head, and be arranged on the force side of described piston rod away from that one end place of described piston head, and be arranged on the pricker of described syringe away from that one end place of described piston rod, on the shaft of described piston rod, movable sleeve is provided with positioning sleeve, the shaft of described piston rod is axially provided with locating slot, the outer surface of described positioning sleeve is provided with the locating hole coordinating described locating slot, lock screw is connected with at described locating hole female thread, described lock screw is against in described locating slot through after described locating hole, the outer surface of described syringe is provided with loose collar, the outer circumference surface of described loose collar is symmetrically arranged with two finger rings, screw is combined with between described loose collar and described syringe, described screw is symmetrically arranged with two.
As preferably technical scheme, the shaft of described piston rod is axially provided with scale.
As preferably technical scheme, described force side is a plane away from that one end of described piston rod, and gummed is fixed with briquetting on this plane, and described briquetting is block rubber, and described briquetting is hemispherical.
As preferably technical scheme, formed between the outer ring place of described piston head and the inner surface of described syringe and seal.
The beneficial effects of the utility model are: this device once can be loaded and repeatedly input, and the amount of each input can control according to use needs, avoid anesthetis to input excessive or very few, while satisfied operation needs, reduce the injury to patient, this device regulates very convenient simultaneously, user regulates the position of positioning sleeve according to required input, and shorten anesthesia duration, the structure of this device is comparatively simple, cost is comparatively cheap, is applicable to promoting the use of.
