Abstract

The invention discloses an angle-adjustable primacaine injector. The angle-adjustable primacaine injector comprises a shell, a blade, a pushing rod, a tail tube, a guide device and a finger ring. More than one recessed track groove is formed in the middle-rear end of the pushing rod. A key groove is formed in the lateral side of a center hole of the guide device. A flat key is inserted in the key groove. The exposed end of the flat key moves along the track grooves. A plurality of pin holes are evenly distributed in the surface, close to one side of the guide device, of the tail tube circumferentially. More than one pin is arranged on the surface, close to the tail tube, of the guide device and is in interference fit with the surface. The pins can be inserted into any pin holes. The angle-adjustable primacaine injector has the advantages that the flat key and the pushing rod constantly move oppositely along the same straight line, the angle among the blade, a hand grip plate and the finger ring can be determined and kept unchanged when the pins are inserted into one or a group of pin holes, the angle of the blade during pushing of an anesthesia liquid tube can be determined according to actual conditions of a patient and gestures of a doctor, and accordingly, anesthetic overflow is controlled.

Description

The green blue fiber crops agent syringe of angle adjustable

Technical field

The present invention relates to the green blue fiber crops of a kind of utensil of the injecting anesthetic medicament in operation on oral cavity, specifically angle adjustable Agent syringe.

Background technology

Local anesthesia is one of necessary means of present dental care, can mitigate pain for patient, in addition to STA, adopts The green blue fiber crops agent syringe of dentistry carries out the anesthesia maneuver that local injection is main flow；But, this syringe alveolus palate on carrying out Anaesthetic excessive phenomenon often occurs during side injection；Its reason is：1. the rubber for puncturing anesthesia liquid pipe of push rod head The blade of plug is flat, and in order to return the needs of hook, the front end of blade wider than tail end that is to say, that blade front end punctures rubber The cut that plug produces, blade rear end cannot be filled up completely with stifled tight, can produce gap；2., in order to be able to easily promote push rod, push away The cooperation of tension can not be designed to, push rod can produce rocking of certain amplitude when mobile between bar and tail pipe, so push rod and fiber crops Liquor-saturated liquid pipe cannot be constantly on same axis that is to say, that blade and rubber closure can not keep plumbness, in other words, knife Piece has tilted cut distending so that gap becomes big；3., when carrying out upper alveolus palate side injection, anesthesia liquid is subject to gravity and pressure Effect flow out from gap, just create the excessive phenomenon of anaesthetic.

The excessive phenomenon of anaesthetic, compares many sometimes, smaller sometimes；Except personal hand strength, injection speed and inclination angle Outside the factors such as degree, an also important factor：The angle of blade；Blade is in vertical state and is in horizontality pair with blade The distending effect of rubber closure is different；When that is injecting, the flow excessive with anaesthetic of the angle residing for blade is relevant.

Content of the invention

The present invention is directed to prior art deficiency, provides a kind of position being accustomed to patients teeth according to the maneuver of doctor Put, control the green blue fiber crops agent syringe of the angle adjustable of the outer spillway discharge of anaesthetic by adjusting blade angle.

In order to solve above-mentioned technical problem, the present invention is addressed by following technical proposals：The green blue fiber crops of angle adjustable Agent syringe includes housing, blade, push rod, tail pipe, guider and finger ring；The middle rear end of described push rod is provided with more than one The rail groove of indent, the centre bore side of described guider is provided with keyway, is inserted with flat key, outside described flat key in described keyway Dew end is along the activity of described rail groove；The surface perimeter of the described tail pipe near described guider side is sold to being evenly equipped with several Hole, the surface near the described guider of described afterbody side is provided with more than one latch and adopts interference fit, described slotting Pin can be inserted in any one of pin-and-hole.

Described guider includes holding plate and guide pipe composition, and described guide pipe holds plate weld with described, or described leads Plate one piece casting is held, described side channel runs through described guide pipe holds plate with described described in Xiang Guanyu.

The periphery wall of described guide pipe is evenly equipped with several and facilitates handss to pinch the vertical striped of rotation.

Surface near the described guider of described afterbody side is symmetrical arranged two described latches.

The present invention compared with prior art, has the advantages that：1st, flat key and push rod are all the time along same straight line phase To motion, so, when latch inserts in some or one group of pin-and-hole, blade with hold plate, the angle of finger ring just can uniquely determine And keep constant, the angle of blade when pushing anesthesia liquid pipe also just can be determined according to the practical situation of patient and doctor's gesture Degree, thus control the excessive flow of anaesthetic.

Brief description

Fig. 1 is the Standard figure of the embodiment of the present invention.

Fig. 2 is the local half-section diagram of the embodiment of the present invention.

Fig. 3 is the Structure explosion diagram of the embodiment of the present invention.

Specific embodiment

With specific embodiment, the present invention is described in further detail below in conjunction with the accompanying drawings：Referring to shown in Fig. 1 to Fig. 3, In figure mark is as follows：Housing 1, blade 2, push rod 3, rail groove 31, raised platforms 32, tail pipe 4, pin-and-hole 41, guider 5, keyway 51st, plate 52, guide pipe 53, vertical striped 54, finger ring 6, flat key 7, latch 8 are held.

The green blue fiber crops agent syringe of angle adjustable includes housing 1, blade 2, push rod 3, tail pipe 4, guider 5 and finger ring 6；Push away The middle rear end of bar is provided with the rail groove 31 of more than one indent, and the centre bore side of guider is provided with keyway 51, keyway Inside it is inserted with flat key 7, the exposed junction of flat key is along rail groove activity；The surface perimeter of the tail pipe near guider side is to being evenly equipped with Multiple pin-and-holes 41, the surface near the guider of afterbody side is provided with more than one latch 8 and adopts interference fit, and latch can Insert in any one pin-and-hole, can be selected for two symmetrically arranged latches；After finger ring and the angle-determining of guider, for one For individual doctor, when carrying out upper alveolus palate side injection, the angle of blade is fixing, and this is a kind of custom, repeatedly repays and tried Afterwards, doctor is certain to find a best angle contributing to control anesthesia liquid spillway discharge.

Guider includes holding plate 52 and guide pipe 53 forms, guide pipe with hold plate weld, or guide pipe with hold plate One piece casting, that is, will be able to fix each other, what thin plate panel beating was made holds the work that plate thickness not cannot meet flat key Need；Side channel runs through guide pipe and holds plate, and the periphery wall of guide pipe is evenly equipped with several and facilitates handss to pinch the vertical bar of rotation Stricture of vagina 54.
