Abstract
The utility model relates to an intra-ocular silicon oil drainage device, which comprises a suction head, a negative-pressure source, and a drainage tube which is connected with the negative-pressure source. The utility model has main points that the intra-ocular silicon oil drainage device is provided with a hollow handle; one end of the hollow handle is matched and connected with the drainage tube; the other end is matched and connected with the suction head, and a small hole which is communicated with the hollow of the handle is arranged on the front part of the hollow handle. The utility model has the advantages of reasonable design, convenient hand operation, easy control, and flexible adjustment of attracted negative pressure. The intra-ocular silicon oil drainage device is favorable for avoidance or instant relief of aspiration of tissues of intra-ocular tissures, and usage is safe.
Description
This utility model belongs to the medical apparatus technical scope, relates to a kind of ophthalmic silicone oil drainage device of surgery of retinal detachment.
The micro-vitrectomy treatment of ophthalmology complicated retinal detachment needs usually to the provisional filling silicone oil of ophthalmic.In the prior art, the taking-up of ophthalmic silicone oil generally all is to adopt the simple and easy drainage apparatus of being made up of suction nozzle, drainage tube and negative pressure source to carry out drain.Though this drainage apparatus is simple in structure, hand-held is convenient inadequately, as controls badly, is easy to mistake and is drawn onto eye inner tissue; Because negative pressure is constant, artificial instant adjusting of inconvenience when mistake is drawn onto eye inner tissue, can not be accomplished immediate decompression again, remove to attract, thereby often cause eye inner tissue, so that retina injury, poor stability.
The purpose of this utility model provides a kind of hand-held of being convenient to, and control easily attracts the negative pressure ophthalmic silicone oil drainage device of flexible immediately, thereby overcomes the above-mentioned defective of existing in prior technology.
The purpose of this utility model is to improve realization on the basis of existing technology, it comprises suction nozzle, negative pressure source and the drainage tube that is connected with negative pressure source, its main points are to also have a hollow handle, one end of this hollow handle has the joint matched with drainage tube, and link to each other with drainage tube, the other end has the joint matched with the suction nozzle seat of suction nozzle, and is connected with suction nozzle by it.
In the operation when being about to that mistake is inhaled or mistake when being drawn onto eye inner tissue, for accomplishing to avoid mistake to inhale or instant the releasing attracts, the front portion of said handle can also have one with the hollow aperture that is communicated with of hollow handle.
Accompanying drawing is a structural representation of the present utility model
Below in conjunction with accompanying drawing this utility model is elaborated:
With reference to the accompanying drawings, 2 is the drainage tubes that link to each other with negative pressure source 1 among the figure, and it has a hollow handle 3, one end of this hollow handle 3 has the joint matched with drainage tube 2, and link to each other with drainage tube 2, the other end has the joint matched with the suction nozzle seat of suction nozzle 5, and is connected with suction nozzle 5 by it.The front portion of said hollow handle 3 also have one with the hollow aperture that is connected 4 of hollow handle 3.
During use, after each part mentioned above connected, syringe needle 5 is inserted in the ophthalmic silicone oil by scleral incision.Determine behind the position that pushing down handle air inlet 4 with forefinger can start vacuum suction source 1 and attract silicone oil; When stopping, unclamping by need forefinger, open air inlet 4, and the interior negative pressure of syringe needle disappears at once and stops to attract, and can remove attraction when inhaling eye inner tissue rapidly especially by mistake, makes silicone oil take out rapid safety method and easily grasps flexibly.
This utility model is reasonable in design, is convenient to hand-held, control easily, but and attract the negative pressure flexible, help avoiding mistake to inhale eye inner tissue or remove immediately and attract, safe and reliable.
