Abstract
The utility model relates to a root canal internal silicone rubber syringe for oral cavity, which comprises a piston (1), an empty cylinder (2) and a syringe needle (3), wherein the piston (1) and the empty cylinder (2) are in slip connection; a plane push head (4) is arranged at the head part of the piston (1); an external thread is arranged at the front end of the empty cylinder (2); the tail end of the empty cylinder (2) is in a horizontal open type or an inclined open type; an internal thread is arranged at the tail part of the syringe needle (3); the external thread of the empty cylinder (2) is connected with the internal thread of the syringe needle (3); the shape of the syringe needle (3) is a bent inverted cone, and the bending angle is 48 degrees. The syringe provided by the utility model is convenient to operate, and the model production time is short; the obtained model is complete and tight, and the quality of the post core root internal-section silicone rubber model is improved; by recycling the empty cylinder, the resources can be saved, and the cost is reduced.
Description
Technical field
This utility model belongs to syringe, is specifically related to silicone rubber syringe in root pipe for a kind of oral cavity.
Background technology
At present, the method that in known conventional silicone rubber stake core root clinically, segment model is produced is: inlay wax direct method in mouthful; Self curing plastic is got wax pattern casting; Red impression compound preparation method; Agar is in conjunction with 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 self curing plastic legal system is got the fusible pattern operating time, and be difficult for accurately, and because self curing plastic polymerization is fast, wayward, bubble, also easily appears 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 portion of silicone rubber of tune being mixed with spiral plugger imports in root pipe, and after it solidifies, this part will be taken out in the lump with silicone rubber pallet.But the weak point of this method is, after the thin portion of silicone rubber imports in root pipe, because the pressure importing is little, so that narrow root tip silicone rubber can not be completely 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 in the utility model is to overcome above-mentioned deficiency, and silicone rubber syringe in 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.
The technical solution of the utility model: silicone rubber syringe in 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 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 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.
This utility model 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 a quality for stake core root inner segment silicone rubber model; 2, empty cylinder is designed to diagonal cut joint formula, is convenient to pack in empty cylinder silicone rubber is as much as possible, also can be designed to horizontal opening formula, needs to be equipped with to adjust mix cup and use 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 reduce cost; 4, the switch of syringe needle is crooked inverted cone, contributes to syringe needle to insert in root pipe, easy to operate, more can guarantee that root pipe inner segment silicone rubber is full, contributes to syringe needle to insert in root pipe, easy to operate, more can guarantee that root pipe inner segment silicone rubber is full.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
