Abstract
An ophthalmic surgical bayonet-typed three-way pipe valve of an intraocular irrigation system has two input connectors, an output connector and a rotary plug to convert the input connectors, wherein, the rotary plug is connected with a selection turn button, and the connector ends of the input connectors after the connecting cavity are provided with inner ring groove bayonets, the external end surfaces of which are provided with 2 to 3 gaps to become the bayonet-typed input connectors; the front end of the output connector is provided with a section of connecting pipe section, while the back end of the connecting pipe section is provided with 2 to 3 card-typed convex edges to become the bayonet-typed output connector. The bayonet-typed connecting structure of the utility model can avoid the slipping of the connectors caused by the back leakage of the silicone oil of the connecting ports during the irrigation of the silicone oil of the current existing system, so as to enable the system to have better connecting tightness, and further to ensure the safe and smooth operations during the intraocular silicone oil irrigation.
Description
Technical field
This utility model relates to the bayonet type threeway pipe valve of the intraocular irrigation system that a kind of ophthalmologic operation uses.
Background technology
Modern closed type triple channel vitrectomy has greatly improved the success rate of operation and the disease therapeuticing effect of vitreoretinopathy.Intraocular irrigation has very important effect in this operation.Because the state of an illness is ever-changing in the operation, the patient need adjust to changed conditions according to situation in the art, selects gas/liquid exchange, gas/oil exchange, oil/liquid exchange or liquid/oil exchange neatly, therefore, in carrying out the intraocular irrigation system of this ophthalmologic operation, the application of threeway pipe valve seems extremely important.The said intraocular irrigation system that is used for ophthalmologic operation generally is made of intraocular irrigation needle tubing and threeway pipe valve, wherein the threeway pipe valve has an output interface, two input interfaces, its output interface is connected with the input port of intraocular irrigation needle tubing afterbody, and two input interface is connected with output interface with two kinds of potting compound tuckers (potting compound can be two kinds in gas, liquid, the oil) respectively.
The threeway pipe valve that uses is generally spiral interface structure at present.The threeway pipe valve is fixed with the thread helix of being abutted against on the mouth that is connected between perfusion needle tubing and the potting compound tucker.Usually, for gas and water sample liquid (balanced salt solution or heavy water) potting compound, because its viscosity is less, they can be smoothly by intrusion pipe and threeway pipe valve, therefore relative less to the pressure of threeway pipe valve access port and exit, when carrying out the exchange of gas/liquid or liquid/gas, generally can not cause the slippage of threeway pipe valve spiral interface.Yet, for the filled with silicone oil thing, because its viscosity is bigger, add the characteristics that its oiliness is easily sliding, when doing the filling of silicone oil ophthalmic, when silicone oil passes in and out the pressure imbalance of intrusion pipe, thereby be easy to accumulate in the intrusion pipe and bleed back and reduce the compactness that interface coincide in the screw thread that enters spiral interface, cause the slippage of access port or exit, as this situation occurring, will cause silicone oil to overflow during operation, the intraocular pressure rapid drawdown, wall of eyeball subsides, and bubble enters ophthalmic, even causes complication in the serious arts such as epichoroidal space is hemorrhage.
Summary of the invention
The purpose of this utility model is the bayonet type threeway pipe valve that the problem for the input that solves the threeway pipe valve of filling system when doing the perfusion of oiliness thing in the perfusion operation within the eye, the easy slippage of output reverse interface designs the intraocular irrigation system that a kind of ophthalmologic operation uses.
The structure of the bayonet type threeway pipe valve that is used for the intraocular irrigation system that this utility model is designed, have two input interfaces, an output interface, and the cock of a conversion input interface, this cock connects one and selects knob, it is characterized in that said input interface is provided with the inner groove bayonet socket in its interface end of refuting after connecing the chamber, have 2 to 3 breach in the outer face of this inner groove bayonet socket, become the bayonet type input interface; The front end of said output interface has one section to refute nozzle belt, is provided with 2 to 3 cassette beads refuting the nozzle belt rear end, becomes the bayonet type output interface.
Bayonet type output interface in this bayonet type threeway pipe valve, can be connected with the perfusion needle tubing that a kind of its input interface end has the inner groove bayonet socket, the structure of the inner groove bayonet socket of the input interface end of this perfusion needle tubing is the same with the inner groove bayonet arrangement of the interface end of the described input interface of this bayonet type threeway pipe valve, as long as the bayonet type outfan plug-in mounting of this bayonet type threeway pipe valve is gone into to pour into the input interface end of needle tubing, cassette bead on this bayonet type outfan is inserted in the inner groove bayonet socket of the input interface end that pours into needle tubing, rotate to an angle, the cassette bead on the bayonet type outfan of threeway pipe valve just is fastened in the inner groove bayonet socket of the input interface end that pours into needle tubing securely again; And two bayonet type input interfaces in this bayonet type threeway pipe valve, the filled with silicone oil device connection that can have bayonet coupling structure (as the bayonet type output interface structure in this bayonet type threeway pipe valve) with its output interface end also can have the bayonet coupling structure with its output interface end or generally the gas transmission or transfusion (the referring to water sample liquid) device of reverse interface structure are connected.When refuting when connecing bayonet type filled with silicone oil device or bayonet type gas transmission or infusion set, only need its cassette interface is inserted the cassette access port of threeway pipe valve, rotate to an angle then, the bead on the described cassette interface just is sticked in the inner groove bayonet socket of threeway pipe valve input interface securely;
When designed bayonet type threeway pipe valve of the present utility model is used in the filling system within the eye, because refuting to connect, its bayonet type avoided existing system when carrying out the silicone oil perfusion, because reverse interface silicone oil occurs and bleeds back the interface slippage that is caused, system is had better refute and connect compactness, thereby when guaranteeing to carry out the perfusion of ophthalmic silicone oil, the safety of operation and smooth.
