Abstract
The invention relates to an oral endodontic silicon rubber syringe. The oral endodontic silicon rubber syringe comprises a piston (1), a tube (2) and a syringe needle (3), wherein the piston (1) is connected with the tube (2) in a sliding way; the head of the piston (1) is provided with a flat pusher (4); the front end of the tube (2) is provided with external threads; the tail end of the tube (2) is horizontally open and can also be a diagonal cut; the tail part of the syringe needle (3) is provided with internal threads; the external threads of the tube (2) are connected with the internal threads of the syringe needle (3); the syringe needle (3) takes the shape of a bent inverted cone; the bending angle is 48 degrees. The oral endodontic silicon rubber syringe is convenient to operate, the time used by manufacturing a mold is short, the mold which is taken out is also complete and closed, the quality of the silicon rubber mold of an inner section of a post-core root is improved, the tube can be recycled, the resource can be saved, and the cost is reduced.
Description
Technical field
The invention belongs to syringe, be specifically related to silicone rubber syringe in the root pipe for a kind of oral cavity.
Background technology
At present, the method that in known silicone rubber stake core root commonly used clinically, segment model is produced is: inlay wax direct method in mouthful; Self curing plastic is got the wax pattern casting; Red impression compound preparation method; Agar is in conjunction with the alginate impression material preparation method; And silicone rubber preparation method.Clinically, its weak point of these methods: 1, during inlay wax direct method production costs, very easily fracture again, distortion; 2, it is long that the self curing plastic legal system is got the fusible pattern operating time, and be difficult for accurately, and because the self curing plastic polymerization is fast, wayward, bubble, also easily appear in the apparatus of touching with one's hand, and it has very niff when operation, easy tissue of burn, and patient is reluctant to accept; 3, it is obviously coarse that red impression compound is produced a root canal wall of core delivery, and tube wall has kick or " tubercle " to produce more.Though it is simple to operate that 4, agar is got stake, the height that its degree of accuracy is still produced not as silicone rubber.When existing silicone rubber is got the interior segment model of a core root, be after getting a road ready, the thin section of the silicone rubber of tune being mixed with the spiral plugger imports in the root pipe, and after it solidifies, this part will be taken out in the lump with the silicone rubber pallet.But the weak point of this method is, after the thin section of silicone rubber imports in the root pipe, because the pressure imported is little, so that narrow root tip silicone rubber can not be fully full, take out interior its root tip of segment model of stake core root imperfect, and the difficult discharge of the air of bottom, have bubble remaining, its model and root pipe leakiness, affect adaptation.During segment model, because one step completed amount is many, bad if operator's speed is grasped in the stake core root of producing many of polydonitas pipe or many pipes of backteeth leaf-comb, will cause the model accuracy that takes out poor, adaptation is bad.
Summary of the invention
Technical problem to be solved by this invention is to overcome above-mentioned deficiency, and silicone rubber syringe in the root pipe for a kind of oral cavity is provided, when this syringe is produced model the time used short, the model of taking-up is also complete, closely sealed,
Improve the quality of stake core root inner segment silicone rubber model.
Technical scheme of the present invention: silicone rubber syringe in the root pipe for a kind of oral cavity, it comprises piston, empty cylinder and syringe needle, piston is slidably connected with empty cylinder, the head of piston is provided with plane and cuts somebody's hair, and the front end of empty cylinder is provided with external screw thread, and the tail end of empty cylinder is the horizontal opening formula, the afterbody of syringe needle is provided with female thread, the external screw thread of empty cylinder is connected with the female thread of syringe needle, described syringe needle be shaped as crooked inverted cone, the angle of bending is 48 °.
It can also be the diagonal cut joint formula that described empty cylinder has tail end, and its inclined-plane is 50 ° with the angle of empty cylinder centrage.
The material that described piston is cut somebody's hair with plane is identical.
The present invention compared with prior art has following beneficial effect: while 1, producing model the time used short, the model of taking-up is also complete, closely sealed, improves the quality of stake core root inner segment silicone rubber model; 2, sky tin is designed to the diagonal cut joint formula, is convenient to, by the silicone rubber empty cylinder of packing into as much as possible, also can be designed to the horizontal opening formula, needs the outfit tune to mix cup and uses together, convenient and swift; 3, empty cylinder and syringe needle are threaded, and can change injection head, safety and sanitation, are beneficial to again the clean to excess silicon rubber in empty cylinder, reach the recycling of empty cylinder, economize on resources, and Cost reduction; 4, the switch of syringe needle is crooked inverted cone, contributes to syringe needle to insert in the root pipe, easy to operate, more can guarantee that root pipe inner segment silicone rubber is full, contributes to syringe needle to insert in the root pipe, easy to operate, more can guarantee that root pipe inner segment silicone rubber is full.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
