Abstract
The utility model relates to a bayonet type intraocular perfusion tube of an intraocular perfusion system for ophthalmic operations, which comprising a perfusion syringe needle, a perfusion cauda and a middle connecting flexible pipe, wherein, an input interface of the perfusion cauda is designed into a bayonet type structure; the bayonet type structure is characterized in that the input interface is provided with an input barge cavity section of which the back end is provided with an inner ring groove bayonet, and the outer end surface of the inner ring groove bayonet is provided with two to three notches. The bayonet type intraocular perfusion tube of the utility model has the advantages that the bayonet type input interface structure of the perfusion cauda which is suitable for being combined with bayonet type tee tube valves or bayonet type silicon oil thrusters with bayonet type output interface structures can solve the problem that the interface of the perfusion tube is easy to slip when the silicone oil intraocular perfusion is carried out.
Description
Technical field
This utility model relates to the bayonet type intraocular irrigation pipe 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 at random should according to situation in the art, select gas/liquid exchange, gas/oil exchange, oil/liquid exchange or liquid/oil exchange neatly, therefore remaining unobstructed and stable intraocular irrigation is key and the assurance that this operation can be safely, carried out smoothly to keep stable intraocular pressure and eyeball shell shape.
The intraocular irrigation system that uses is made up of a three-member type intrusion pipe and a threeway pipe valve usually at present.The three-member type intrusion pipe is connected flexible pipe with the centre and is formed by perfusion syringe needle, perfusion tail, and wherein, the perfusion tail has the input interface structure that is connected with the output interface of threeway pipe valve.Existing perfusion tail is the structure that is connected and fixed that adopts a kind of screw-type with being connected of output interface of threeway pipe valve, this syndeton is when carrying out the exchange of gas/liquid (said liquid is water sample liquid-balanced salt solution or heavy water) or liquid/gas, when also promptly carrying out the perfusion of gas or liquid, because the viscosity of gas and water sample liquid is little, the general slippage that can not cause threeway pipe valve and perfusion tail connecting port, but when doing the filling of silicone oil ophthalmic, because the silicone oil viscosity is big, when silicone oil passes in and out the pressure imbalance of intrusion pipe, be easy to accumulate in the intrusion pipe and bleed back to enter the threeway pipe valve and pour into refuting of tail connecting port and connect the compactness of coincideing from the low at first interface of face in the screw thread, cause the slippage of access port or exit, during operation as this situation occurring, to cause silicone oil to overflow, 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.
In addition, because intrusion pipe is to be connected three of flexible pipes with the centre and to be formed by connecting by perfusion syringe needle, perfusion tail, connected mode between these three is normally fixed by the method that will connect the roll line binding with silk thread, it is fixing often not firm, when carrying out silicone oil perfusion operation, also cause the binding roll line to get loose easily, cause taking place above-mentioned operation dangerous problem.
Summary of the invention
The purpose of this utility model is to propose a kind of bayonet type intraocular irrigation pipe, the problem of the easy slippage of each interface of intrusion pipe when carrying out the silicone oil intraocular irrigation with solution.
Realize the technical scheme of this utility model purpose, be to make perfusion syringe needle, perfusion tail and the middle input interface that is connected the perfusion tail in flexible pipe three parts of forming the intraocular irrigation pipe be designed to the bayonet type structure, the characteristics of this bayonet type structure are: input interface has an input and refutes and connect the chamber section, be provided with an inner groove bayonet socket refuting the rear end that connects the chamber section, have 2 to 3 breach in the outer face of this inner groove bayonet socket.
The bayonet type intraocular irrigation pipe of this utility model design, the bayonet type input interface structure of its perfusion tail, mainly be applicable to its output interface on have the cassette bead, this bead can form mutual bayonet type threeway pipe valve or the bayonet type silicone oil propeller that engages the cassette output interface structure of coupling with the inner groove bayonet socket on the described perfusion tail input interface and be used in combination, only need described bayonet type threeway pipe valve or the angle of rake cassette output interface of bayonet type silicone oil are inserted the perfusion tail input interface of this bayonet type intraocular irrigation pipe during use, rotate to an angle then, bead on the described cassette interface just is sticked in the inner groove bayonet socket of perfusion tail input interface securely, forms not eely combination.
The design of further improvement of the utility model is middle flexible pipe and perfusion syringe needle and the syndeton of pouring into the urogenesis integral type of connecting that makes this bayonet type intraocular irrigation pipe.Pouring head in the bayonet type intraocular irrigation pipe of the present utility model and perfusion tail can be made by metal or rigid plastics, the middle flexible pipe that connects can adopt the metal hose of flexible plastic pipe or interior cover flexible plastic pipe to make, adopt the modern industry processing technique to be easy to described three component processing of this bayonet type intraocular irrigation pipe are integral the formula structure, the drawback that three connecting ports need have been bundled fixed trouble and caused therefrom with silk thread temporarily when this has just been avoided use.
This bayonet type intraocular irrigation pipe has following technique effect:
1, the perfusion tail adopts the bayonet type input interface, can refute and connects by forming cassette with the threeway pipe valve of cassette output interface or bayonet type silicone oil propeller, can guarantee bonded compactness, is not easy slippage, thereby guarantees the safety of operation and smoothly.
2, adopt the integral type design, eliminated the danger of the easy slippages of three parts reverse interfaces, use safer and convenient and swift.
3, designed perfusion tail bayonet coupling structure is applicable to that multiple refuting connects object, both has been suitable for bayonet type threeway pipe valve and bayonet type silicone oil propeller, also is suitable for refuting connecing common tube for transfusion, can satisfy different modus operandis and patient's custom.
