Description
Technical field
This utility model relates to a kind of modified form anesthetic needle.
Background technology
Previous necessary step of performing the operation is carried out in anesthesia, by the local anesthesia to patient body, the pain that patient is suffered in operation process can be avoided, for large-area wound operation on mouth, need the both sides multi-point injection anesthetis at surgical wound, existing way completes narcotic injection by anesthetic needle, but anesthetic needle of the prior art can only rely on the operating experience of doctor to carry out the control of anesthetis input quantity, when needs multi-point injection, if single-point injection too much, then the anaesthesia dosage of other some positions is probably inadequate, cause the pain of patient in operation process.
Summary of the invention
The technical problems to be solved in the utility model is to provide a kind of modified form anesthetic needle, this device can complete narcotic quantitative conveying by the cooperation of quantitative slot and quantitative bar, meet surgery anesthesia needs, corresponding syringe can be changed flexibly according to the number of times of required quantitative input simultaneously, simple to operation.
For solving the problem, this utility model adopts following technical scheme:
A kind of modified form anesthetic needle, comprise syringe cover, syringe, piston head, piston rod and pricker, described syringe is movably arranged in described syringe cover, the inner surface of described syringe is axially provided with plural quantitative slot, described piston head is engaged in described syringe, the outer ring of described piston head is provided with the quantitative bar coordinating described quantitative slot, described piston head coordinates described piston rod, described piston rod extends to described syringe outside away from that one end of described piston head, the left end of described syringe has installation end, the left end of described syringe cover is provided with the through hole coordinating described installation end, described pricker is arranged on described installation end, described piston rod is provided with press-side away from that one end of described piston head, the close right end position place of described syringe cover outside is symmetrically arranged with two finger rings.
Preferably, described finger ring and described syringe overlap for integral type structure, and the outer surface of described syringe cover is axially provided with scale, and described syringe overlaps for transparent PVC plastics are made.
Preferably, described piston head and described quantitative bar are integral type structure, and the inner surface of described piston head and described syringe is fitted, and formed and seal between described piston head and described syringe.
Preferably, described quantitative slot is arc-shaped slot.
Preferably, described press-side is provided with spherical pressing pad away from that one end of described piston rod, and described pressing pad is that rubber is made.
The beneficial effects of the utility model are: this device can complete narcotic quantitative conveying by the cooperation of quantitative slot and quantitative bar, meet surgery anesthesia needs, corresponding syringe can be changed flexibly according to the number of times of required quantitative input simultaneously, simple to operation, the structure of this device is simple, with low cost, be applicable to promoting the use of.
Accompanying drawing explanation
In order to be illustrated more clearly in this utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
