Description
Technical field
The utility model relates to a kind of dental medical apparatus, especially a kind of oral cavity partial anesthetic injecting device.
Background technique
Oral cavity partial anaesthetizes (oral local anesthesia) abbreviation local anaesthesia, refers to and is temporarily hindered with local anesthetic
The Sensory conduction of nerve endings and fiber in off line body certain area, so that the area Shi Gai pain disappears；Exact meaning should be
Part is painless, i.e., in addition to analgesis, other feelings such as press, temperature sensation there are still；Patient still keeps awake consciousness.At present
It often needs to anaesthetize gum in the process of dental care, usually uses syringe direct injection anesthetic, but injecting
In the process since gum is more tough and tensile, syringe needle is difficult to be pierced into, and drug is difficult to inject into gum, infuses in anesthetic
It needs to provide compared with high thrust syringe when penetrating, so that being difficult to control syringe needle in injection is pierced into depth, and due to conventional note
The syringe needle of emitter is more elongated, flexible when stress is larger to fracture, and is easy patient harm；And it often needs over the course for the treatment of internal
Gum is injected, and due to the structure of conventional syringe, when injection is commonly present dead angle, cause the injection angles of interior gum limit compared with
Greatly, it is difficult to carry out injection operation.Therefore, when oral cavity partial is anaesthetized, that there are injection operations is cumbersome, syringe needle thorn for existing syringe
Enter that depth is difficult to control, injection needle frangibility, injection speed be difficult to the problem of controlling, and be difficult to internal gum and infused
It penetrates.
Utility model content
The purpose of the utility model is to provide a kind of oral cavity partial anesthetic injecting devices.The utility model is in oral cavity office
Convenient for injection observation when portion anaesthetizes, injection operation is convenient, and syringe needle is pierced into depth and keeps away convenient for control convenient for controlling injection speed
Injection needle fractures when exempting from injection, and simplifies interior gum injection operation.
The technical solution of the utility model includes: a kind of oral cavity partial anesthetic injecting device, including fixed facing, the injection of outer gum
Auxiliary device, interior gum injection auxiliary block and injection needle, fixed facing lateral wall are equipped with sliding and slot, on the inside of fixed facing
Wall is equipped with injection location hole, outer gum injection aid and sliding fluting connection, interior gum injection auxiliary block and fixed facing
Inner sidewall connection；The outer gum injection aid includes connecting wedge, is equipped with sheath hose above connecting wedge；In described
Gum injects auxiliary block and is equipped with needle insertion hole, needle insertion hole and the injection location hole pair being located on fixed facing inner sidewall
Together；The injection needle is located in connecting wedge by sheath hose, and injection needle also injects auxiliary block by being located at interior gum
On needle insertion hole connect setting.
In a kind of oral cavity partial anesthetic injecting device above-mentioned, the fixed facing is made of soft silica gel material, fixed tooth
Set top is equipped with observation slot.
In a kind of oral cavity partial anesthetic injecting device above-mentioned, the injection needle includes connection hose, connects hose one
End is equipped with injection connector, and the connection hose other end is equipped with bent injection needle.
Compared with prior art, facing is fixed made of setting soft silica gel material, positioning can be provided for injection operation,
It by the way that outer gum injection aid is arranged, can be moved on sliding fluting by connecting wedge, adjusting injection position, when use
Injection needle is arranged in connecting wedge by sheath hose, gum can be punctured and injected, injection operation is convenient, and needle
Head is pierced into depth convenient for control；By setting connection hose, injection connector and bent injection needle, when injection, only need to be by common note
Emitter is connect with injection connector, convenient for controlling injection speed, because the excessive injection needle of thrust is rolled over when avoiding injecting
It is disconnected；Auxiliary block is injected by gum in being arranged, interior gum is pierced into convenient for injection needle and is injected, while by being located at fixed tooth
Injection location hole on set inner sidewall finds injection position accurately, simplifies interior gum injection operation.In conclusion the utility model is in mouth
Convenient for injection observation when chamber local anaesthesia, injection operation is convenient, and syringe needle is pierced into depth convenient for control, convenient for controlling injection speed
Degree avoids injection needle when injection from fractureing, and simplifies interior gum injection operation.
