The invention provides a negative-pressure suction pipeline system for an ophthalmic phacoemulsification instrument, belonging to the technical field of negative-pressure suction pipeline systems. The negative-pressure suction pipeline system comprises a suction pipeline, a hard liquid collecting box, a current limiter and a pipeline, wherein the hard liquid collecting box is provided with a filter screen; the pipeline is connected with a negative-pressure source; the tail end of the suction pipeline is connected with the liquid inlet of the hard liquid collecting box with the filter screen; the liquid outlet of the hard liquid collecting box with the filter screen is communicated with the pipeline which is connected with the negative-pressure source; and the current limiter is connected to the pipeline which is connected with the negative-pressure source. The negative-pressure suction pipeline system is mainly used for replacing a negative-pressure pump system of the phacoemulsification instrument to provide stable, reliable and quick responding negative-pressure suction for ophthalmic surgery. The negative-pressure suction pipeline system has the same functions as a negative-pressure pump in the conventional phacoemulsification instrument, can be used for providing stable, reliable and quick responding negative-pressure suction for surgery, has the advantages of simple structure, low cost, easiness in maintaining and the like in comparison to the conventional negative-pressure pump system for the phacoemulsification instrument, and can be used for completely replacing the conventional negative-pressure pump for the phacoemulsification instrument.
Description
technical field [0001] The invention relates to a negative pressure suction pipeline system for an ophthalmic phacoemulsification apparatus, belonging to the technical field of negative pressure suction pipelines. Background technique [0002] Cataract phacoemulsification is the main surgical method for the treatment of cataract at present, and the cataract phacoemulsification instrument is the key surgical equipment for cataract phacoemulsification. The negative pressure pump is an important part of the phacoemulsification apparatus, accounting for about 50% of the cost of the phacoemulsification apparatus. The negative pressure pump is mainly responsible for providing stable, continuous and quick-response negative pressure suction for the operation during the operation. Therefore, the quality and price of the negative pressure pump directly determine the quality and price of the phacoemulsification instrument. Furthermore, it indirectly affects the quality and cost of ea...
