Abstract
The invention discloses a silicon rubber syringe, which is composed of a piston, a hollow barrel, a hollow barrel head with a screw, and a detachable bent needle head with a screw buckle. The silicon rubber syringe is characterized in that a planar push head is arranged on the head of the piston; an external thread is arranged on the hollow barrel head; the needle head is inverted-cone-shaped; and the screw buckle is arranged on the tail of the needle head and closely screwed together with the thread on the hollow barrel head. The silicon rubber syringe disclosed by the invention is convenient to operate and short in the time used during model production; and the model taken out is complete and closely sealed, thus improving the quality of the silicon rubber model in the inner section of a post core root; and via recycling for the hollow barrel, resources can be saved and cost can be reduced.
Description
Technical field
The invention belongs to syringe, be specifically related to a kind of silicone rubber syringe.
Background technology
At present, the method that segment model is produced in the known silicone rubber stake nuclear root of commonly using clinically 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, because the 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 nuclear 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 stake nuclear root, be after getting a road ready, the thin section of silicone rubber of accent being mixed with the spiral plugger imports in the root pipe, and after it solidified, 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 that imports is little, so that narrow root tip silicone rubber can not be fully full, then its root tip of segment model is imperfect in the taking-up stake nuclear root, and the difficult discharge of the air of bottom, has bubble remaining, its model and root pipe leakiness affect adaptation.When in the stake nuclear root of producing many of polydonitas pipe or many pipes of backteeth leaf-comb during segment model, bad if operator's speed is grasped because one step completed amount is many, 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 a kind of silicone rubber syringe is provided, when this syringe is produced model the used time short, the model of taking-up is complete, driving fit also, improves the quality of stake nuclear root inner segment silicone rubber model.
Technical scheme of the present invention: a kind of silicone rubber syringe by piston 1, empty cylinder 2, with the empty cylinder head of buckle, and consists of with dismountable bending syringe needle 3 of buckle.It is characterized in that: piston crown is provided with the plane and cuts somebody's hair 4, and an empty cylinder head is provided with external screw thread, and 3 one-tenths inverted cone shapes of syringe needle, syringe needle 3 afterbodys are provided with buckle and closely are screwed in the screw thread of an empty head.
The present invention compared with prior art has following beneficial effect: when 1, producing model the used time short, the model of taking-up is complete, driving fit also, improves the quality of stake nuclear root inner segment silicone rubber model; 2, 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 the empty cylinder, reach the recycling of empty cylinder, economize on resources Cost reduction.
