Abstract
The invention discloses a plastic needle for a tooth root canal, comprising a needle base and a needle tube, wherein the root of the needle tube is connected with the needle base and is provided with a handle, and the needle base, the needle tube and the handle are molded by injecting plastic material. Because the plastic needle is molded by the plastic material, when the plastic needle is in use, the needle tube can be bent to enter along the wall of the tooth root canal without being blocked until contacting the needed position of the tooth root canal so as to wash, absorb liquid and fill filler, and the needle tube can be used after being bent by a center angle near the root of the tooth root canal. The plastic needle can be operated and used conveniently and can be destroyed easily after being used one time.
Description
Technical field
The invention belongs to dental tool, relate in particular to a kind of be used in dentistry to the root pipe wash, the plastics pin of imbibition, filling implant.
Background technology
The effective flushing needle of root of dentist's use in the past, what adopt is by bonding small dimension dentistry flushing needle after firm by plastics needle stand and metal butt-ended tube more, because root tube passage shape differs, narrow, all tangible one-tenth bending, like this, to root canal portion wash, imbibition and filling implant make troubles, metal needle can not be from line bend, can not totally remove the dental pulp influence of root pipe portion in the tooth process and controls the tooth effect thereby control; Because metal needle is difficult for destroying, if root canal has used unholiness flushing needle, easily causes nosocomial infection, damages to the patient.
Summary of the invention
Purpose of the present invention is exactly the problems referred to above that exist at existing flushing needle, provide a kind of can be deep into root pipe bottom can be with the bending of root tube passage crooked, disposable plastic needle for tooth root canal.
For achieving the above object, the present invention adopts following technical scheme: a kind of plastic needle for tooth root canal, comprise plastics needle stand and needle tubing, and the needle tubing root links to each other with needle stand, at the needle tubing root handle is arranged, and needle stand, needle tubing and handle are by the plastic material injection mo(u)lding.
Described plastic material is polypropylene, polyethylene or ABS resin.
The needle stand inner chamber is the standard Luer joint, and external screw thread is arranged on the needle stand.
Handle is symmetrical lamellar.
Handle is prismatic
Handle is a terrace with edge shape.
The syringe tip internal diameter is not more than 0.4mm, and external diameter is 0.3mm～0.6mm.
On the needle tubing outer wall dimension line is arranged.
The needle tubing root is bending.
Adopt the plastic needle for tooth root canal of technique scheme, because the material that adopts is plastics, in use needle tubing can with the root canal wall bending enter be not obstructed and arrive that desired location is washed, imbibition or filling implant, also the plastics pin can be used after bending to certain angle near the pipe root, have easy for operation, disposable use is with the easy characteristics of destroying in back.

The specific embodiment
Embodiment 1: plastic needle for tooth root canal as shown in Figure 1, comprise needle stand 2 and needle tubing 4, the needle tubing root links to each other with needle stand, at the needle tubing root handle 3 is arranged, handle is symmetrical lamellar, be printed on dimension line 5 on the needle tubing outer wall, as shown in Figure 2, needle stand inner chamber 6 is the standard Luer joint, external screw thread 1 is arranged on the needle stand, through single injection-molded, plastic material can be polypropylene, polyethylene or ABS resin, or other harmless macromolecular material by plastic material for needle stand 2, needle tubing 4 and handle 3.
The size of needle tubing from the root to the end dwindled gradually, and according to the size of people's root pipe caliber, proper syringe tip external diameter is between 0.3mm～0.6mm, and internal diameter is not more than 0.4mm.
The needle stand inner chamber adopts the standard Luer joint, is to be convenient and the supporting use of locking-type joint syringe, and needle stand is furnished with screw thread outward, is convenient to cooperate closely with syringe, and handle is convenient to screw when assembling plastics pin, prevents to skid, and causes assembling tightly not leak.At near the even printed dimensions labelling between the about 12mm needle tubing root with apart from syringe tip, be convenient to user and observe the position that needle tubing is inserted into the root pipe.
Also can make angle of needle tubing root bending, enter the oral cavity to make things convenient for needle tubing.
Because adopt plastic material, in use needle tubing can enter with the root canal wall bending and not be obstructed, and arrive that desired location is washed, imbibition or filling implant.
Embodiment 2: in the present embodiment, as shown in Figure 3, being shaped as of handle 3 is prismatic, and other is identical with embodiment 1.
Embodiment 3: in the present embodiment, as shown in Figure 4, handle 3 be shaped as terrace with edge shape, other is identical with embodiment 1.
