Abstract
The utility model relates to an oral local anaesthetic instrument, which is used for the anaesthesia in an oral surgical operation, and is composed of a shell, a program-controlled circuit board, a transformer, an inner-rotating impulse driving motor, a transmission shaft, a dose distribution regulator, a speed regulation button and a pedal pneumatic switch which are assembled. The machine transmits and feeds narcotic, needles and handles, and anesthesia can be executed at any position needed. That the injection narcotic with slow flow rate makes patients feel painless breaks the backward oral anesthesia method. The anesthesia effect can be obtained scientifically and reasonably and the pressure and fear of patients can be reduced by the control of computer programming. The handle is fine and flexible, so the direction and position of the needle can be altered and adjusted randomly in the course of injection. The operation is simple and convenient.
Description
Technical field
When relating to operation on oral cavity, this utility model is used to a kind of instrument of anaesthetizing.
Background technology
Be expelled to the oral cavity after dentistry local anesthesia at present adopts needle tubing that anaesthetic is sucked and anaesthetize the position, because the thick Artificial Control injection of needle tubing is not good.
Summary of the invention
The purpose of this utility model is to avoid weak point of the prior art, can anaesthetize arbitrarily and oral cavity partial anaesthetic device product simple to operation by any desired area in the oral cavity and provide a kind of.
Can take following technical scheme to realize purpose.
The oral cavity partial anaesthetic device comprises: a few part assemblings of shell, program control wiring board, transformator, inner-rotary type pulse driving motor, power transmission shaft, dose distribution regulator, speed governing button and foot-operated pneumatic switch constitute.
The relative prior art of the technical program has following advantage and effect:
Present technique machine driving feeding anaesthetic, syringe needle, handle can be anaesthetized arbitrarily by any desired area in the oral cavity, and are slug flow speed injection anaesthetic, make patient have no pain; Break backward oral anesthestia method, make the painless sensation of patient; Because computer programming control, can be scientific and reasonable obtain anaesthetic effect, reduce patient's the pressure or the feared state of mind; When anesthetics is injected, carefully and flexibly can change arbitrarily, adjust syringe needle direction and position owing to handle, simple to operation.
