Description
Technical field
This utility model relates to a kind of department of stomatology therapeutic appliance, particularly discloses a kind of posterior teeth root canal medical needle.
Background technology
The conventional posterior teeth root canal medical needle of the department of stomatology comprises barbed broach and smooth pin, the taper needle body that its structure is whole smooth at present.Restriction due to oral cavity mouth opening, between the jaw of backteeth, working place is little, the about 20mm of posterior teeth root canal length left and right, existing posterior teeth root canal medical needle length far surpasses free space length, cause the inconvenience of clinical manipulation, must be using after posterior teeth root canal medical needle bending, due to posterior teeth root canal carefully and how crooked, posterior teeth root canal medical needle difficult insertion root pipe after bending and more frangibility gulp down apparatus because the easy slippage of needle body whole smooth causes patient by mistake.
Summary of the invention
The purpose of this utility model is to overcome the defect existing in prior art, and a kind of simple in structure, posterior teeth root canal medical needle of preventing from gulping down by mistake, using safely, facilitate clinical manipulation is provided.
This utility model is achieved in that a kind of posterior teeth root canal medical needle, comprise tapered needle body, it is characterized in that: described needle body is from bottom to top connected to form successively by active section, connector, handle, described handle is provided with fixed hole, and the surface of described connector is shiny surface.
The outer surface of described handle is provided with mesh antiskid stricture of vagina or striated anti-slip veins.
The surface of described active section is the smooth or surperficial agnail that is provided with.
The height of described active section is 10-12mm, and the height of described connector is 10-15mm, and the height of described handle is 8-12mm.
Described fixed hole is oval.
The beneficial effects of the utility model are: simple in structure, production and processing convenience.By handle being set and fixed hole being set on handle, fixed hole, for threading, prevents that the patient who is caused by slippage from gulping down of the present utility model by mistake, thereby has guaranteed use safety.
Accompanying drawing explanation
Fig. 1 is this utility model structural representation.
Wherein: 1, active section; 2, connector; 3, hands handle; 4, fixed hole; 5, agnail; 6, mesh antiskid stricture of vagina.
The specific embodiment
According to Fig. 1, this utility model comprises tapered needle body, described needle body is from bottom to top connected to form successively by active section 1, connector 2, handle 3, described handle 3 is provided with fixed hole 4, described fixed hole 4 is oval, described fixed hole 4 prevents that for threading this utility model from gulping down because of slippage by mistake, and the surface of described connector 2 is shiny surface.The outer surface of described handle 3 is provided with mesh antiskid stricture of vagina 6, further prevents slippage, handled easily.The surface of described active section 1 is smooth or active section 1 surface is provided with agnail 5.The height of described active section 1 is 10-12mm, and the height of described connector 2 is 10-15mm, and the height of described handle 3 is 8-12mm.Can guarantee that so effective active length of the present utility model (it is posterior teeth root canal length that active section adds connector >=20mm) can longly not affect again the operation of backteeth district, and mesh antiskid stricture of vagina 6 structures of handle 3 can prevent apparatus slippage, fixed hole 4 threading prevent that apparatus from being gulped down by mistake.
