Abstract
The utility model discloses an oral cavity anaesthetic needle, which comprises a needle tube, a needle handle, a piston fixed to the front end of the needle handle and a needle body which is arranged at the front end of the needle tube and is communicated with the needle tube. The oral cavity anaesthetic needle is characterized in that a positioning device is arranged on the rear part of the needle handle; further, the needle body is a curved needle body which is bent to form a certain radian; the positioning device is a positioning cap which is in threaded connection with the needle handle; and a power-assisted plate is arranged on the rear part of the needle tube. According to the oral cavity anaesthetic needle, the positioning device is in threaded connection with the needle handle; and the injection dose can be mastered accurately by the positioning device during emergency, and anaesthetic injection can be conveniently performed in oral cavities by the curved needle body.
Description
Technical field
This utility model relates to medical instruments field, specifically, relates to a kind of oral anesthestia pin.
Background technology
Anesthesia is preoperative necessary preparation.At present, the anesthetic needle that generally adopts clinically is made up of needle tubing, needle handle, piston and needle body, and needle tubing is straight, when anaesthetizing to patient, for the tissue anesthesia of body surface than being easier to, for the anaesthetic effect in the oral cavity difficulty of ten minutes then.Have again be exactly the injection of existing anesthetic needle entirely with doctor's experience and the observation of eyes, when the situation that runs into burst, like patient's struggle etc., ID can not be held, and causes the waste of anaesthetic or anaesthetic effect not enough.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned defective, and providing a kind of can carry out the oral anesthestia pin that oral anesthestia when injection is simple to operate, can control ID to patient.
For addressing the above problem, the technical scheme that this utility model adopted is:
A kind of oral anesthestia pin, the needle body that comprises needle tubing, needle handle, is fixed on the piston of needle handle front end and is arranged on the needle tubing front end and is communicated with needle tubing is characterized in that: the rear portion of said needle handle is provided with positioner.
Further say:
Said needle body is the crooked needle body that bends to certain radian.
Said positioner is the positioning cap that is threaded on the needle handle.
The rear portion of said needle tubing is provided with the power-assisted plate.
Owing to adopted technique scheme; Compared with prior art; The positioner that on needle handle, is threaded in this utility model rely on positioner can prepare to hold ID when running into emergency case, and the needle bent body can be anaesthetized injection easily in the oral cavity.
Below in conjunction with the accompanying drawing and the specific embodiment this utility model is done further description.
Description of drawings
Accompanying drawing is the structural representation of the embodiment of this utility model.
Among the figure: the 1-needle handle; The 2-positioning cap; 3-power-assisted plate; The 4-needle tubing; The 5-piston; The 6-needle body.
The specific embodiment
Embodiment:
A kind of oral anesthestia pin, shown in accompanying drawing, the needle body that comprises needle tubing 4, needle handle 1, is fixed on the piston 5 of needle handle 1 front end and is arranged on needle tubing 4 front ends and is communicated with needle tubing 4.The rear portion of said needle handle 1 is provided with positioner.In the present embodiment, said needle body 6 is for bending to the crooked needle body of certain radian, and the needle bent body can be injected the position of being inconvenient to inject.Said positioner is the positioning cap 2 that is threaded on the needle handle 1, and the staff can pass through positioning of rotating medicated cap 2, limits the dosage of injection through the evolution of positioning cap 2, does not need the staff to rely on the observation of eyes to grasp the dosage of injection.The rear portion of said needle tubing 4 is provided with power-assisted plate 3, and the staff can be by the strength of power-assisted plate 3, when the anesthesia of carrying out than the position, huttriall, increases the dynamics that pierces through, and firmly evenly, has alleviated staff's work difficulty.
