Abstract
The utility model provides a bayonet spiral push type silicone oil injector, comprising a syringe, a piston and a piston push bar. The piston push bar is provided with external threads, a helical propelling sleeve provided with matching internal threads is assembled on the rear end opening of the syringe, the piston push bar is screwed in the syringe via the matching internal threads of the helical propelling sleeve, and the head of the syringe is provided with 2 to 4 bayonet type flanges to became a bayonet output interface. In the utility model, the silicon oil finished product is encapsulated in the syringe by the piston, and the piston push bar can propel in a rotating way in the syringe by being rotated to push the piston to move forward, so the silicon oil is outputted from the delivery outlet of the syringe. The bayonet type output interface of the syringe is docked with a matching intraocular perfusion tube provided with an inner ring groove bayonet to carry out the intraocular silicon oil perfusion operation, which can inject the ophthalmic silicon oil into the eyes safely and solve the problems that a roll booster is required when the silicon oil is injected and the oil leak and air leak of the connecting opening happen when injecting.
Description
Technical field
This utility model relates to a kind of syringe that row ophthalmic filled with silicone oil is adopted in ophthalmologic operation.
Background technology
Eye has stable physicochemical property with silicone oil, and refractive index is similar to vitreous body, simultaneously certain viscosity (1000-15000CS) and surface tension are arranged again, thereby the filling of silicone oil ophthalmic is the conventional means for the treatment of complicated retinal detachment clinically.In operation during row ophthalmic filled with silicone oil, because the viscosity of silicone oil is higher, when adopting conventional piston type syringe, resistance is bigger when promoting silicone oil, is not easy silicone oil filling is gone into ophthalmic.Because the oiliness characteristic of silicone oil, if when plugging into intrusion pipe, there is a little silicone oil to spill, will have influence on silicone oil syringe port and intrusion pipe interface between compactness, often cause silicone oil from the seam seepage, influence amount and speed that silicone oil enters ophthalmic, but sometimes in addition entrained air bubbles enter ophthalmic.Silicone oil injects for convenience, has dual mode to realize the silicone oil boosting at present clinically.A kind of is to adopt silicone oil power-assisted frame, and this is made of metal, and the syringe that silicone oil will be housed during use is placed in the frame, the piston of pushing syringe in rotary manner, thus make silicone oil inject ophthalmic.This method is cumbersome, need install during use, and volume is longer easily slippage, therefore inconvenient patient's operation.Another kind method is that silicone oil is poured out from commercially available silicone oil syringe, changes another Luer's syringe over to, in rotary manner silicone oil is injected ophthalmic.This method needs to change silicone oil over to another container, loses time and silicone oil, pollutes easily.
Summary of the invention
The purpose of this utility model is that a kind of energy of design is convenient and swift, safely with the silicone oil syringe of eye with silicone oil injection ophthalmic, and the problem of connecting port leakage of oil and gas leakage when needing booster and injecting when silicone oil is injected to solve.
For this reason, this reality has had new design a kind of bayonet socket screw-pushing type silicone oil syringe, its structure comprises injection tube, piston and piston pushing ram, it is characterized in that having external screw thread on the said piston pushing ram, the rear port of injection tube is equipped with a helical propelling sleeve with supporting female thread, the piston pushing ram is gone into injection tube by the supporting female thread spinning of helical propelling sleeve, and the head of said injection tube has 2～4 cassette beads, becomes the bayonet type output interface.In this utility model, said injection tube is encapsulated in the injection tube by piston for the silicone oil finished product is housed, by the rotary-piston pushing ram, this piston pushing ram can rotate propelling in injection tube, and then promotes piston-advance, makes the delivery outlet output of silicone oil from injection tube.The bayonet type output interface of injection tube and a kind of intraocular irrigation pipe with inner groove bayonet socket that is complementary are refuted connect, can carry out ophthalmic silicone oil perfusion operation.
Assembling mode between said helical propelling sleeve and the injection tube is to make helical propelling sleeve can be fastened on the rear port of injection tube.Can adopt the frame mode that is threaded that helical propelling sleeve is fixed on the rear port of injection tube, the frame mode that also can adopt bayonet socket to connect is fixed on helical propelling sleeve the rear port of injection tube.
This utility model is with a kind of simple and easily-assembled structure, realize directly exporting with the propulsion mode promotion silicone oil of spiral, when this bayonet socket of clinical practice screw-pushing type silicone oil syringe, it is more steady and easy that the mode by screw propulsion can make silicone oil enter ophthalmic, and speed is more easy to control.Because the effect of head bayonet socket is no longer as the easy slippage of existing product.When producer's packing silicone oil, in the syringe of silicone oil directly can being packed into and need not when undergoing surgery, to change once more container, thereby reduced the chance of secondary pollution.

The specific embodiment
Be described in further detail below in conjunction with the CONSTRUCTED SPECIFICATION of accompanying drawing this utility model embodiment:
Embodiment one
The structure of present embodiment as shown in Figure 1, by injection tube 1, piston 2, helical propelling sleeve 3 and piston pushing ram 4 constitute, the output interface place of injection tube 1 has two symmetric cassette beads 11 (as shown in Figure 2), the urceolus mask at the rear portion of injection tube 1 has external screw thread, the front end of helical propelling sleeve 3 has an adapter sleeve 31, this adapter sleeve has the female thread that matches with the external screw thread of injection tube 1 rear end, the rear end face (as shown in Figure 3) that helical propelling sleeve 3 can be spun be installed to injection tube 1 thus, the rear end of helical propelling sleeve 3 is the screw propulsion sleeve 32 of a necking down, this sleeve has female thread, has the external screw thread (as shown in Figure 4) that matches with the female thread of screw propulsion sleeve 32 on the piston pushing ram 4, there is handle 5 rear end of piston pushing ram 4, piston pushing ram 4 is gone into injection tube 1 by screw propulsion sleeve 32 spinnings of helical propelling sleeve 3, and pushing and withstanding is to the rear end face of piston 2.When using this screw-pushing type silicone oil syringe and carrying out the filling of silicone oil ophthalmic, annotated in the injection tube 1 silicone oil has been housed, the bayonet type output interface that makes injection tube is refuted with the intraocular irrigation pipe with inner groove bayonet socket and is connect, can make silicone oil inject ophthalmic by the piston of rotary-piston pushing ram 4 pushing syringes by the intraocular irrigation pipe.
