The invention provides a flow regulator for an ophthalmic phacoemulsification instrument. One end of an inflow pipeline which is connected with a hard liquid collecting box is communicated with the second port of a medical three-way valve, and the other end of the inflow pipeline is communicated with the inlet of the hard liquid collecting box; one end of a pipeline of which the inner diameter is the same as that of a phacoemulsification instrument suction pipeline is communicated with the third port of the medical three-way valve, and the other end of the pipeline is communicated with the first port of a three-way connecting joint; one end of an outflow pipeline which is connected with the hard liquid collecting box is communicated with the outlet of the hard liquid collecting box; the other end of the outflow pipeline which is connected with the hard liquid collecting box is communicated with the second port of the three-way connecting joint; and a flow regulating element is connected in series to the outflow pipeline which is connected with the hard liquid collecting box. The flow regulator is used for providing a low-flow safe working mode for the phacoemulsification instrument during performance of ophthalmic complicated cataract operation, and has the advantages of rapid switching, no greater change of a phacoemulsification instrument main body by being externally connected to a negative-pressure pipeline, great improvement on the performance of the phacoemulsification instrument, and the like.
Description
technical field [0001] The invention relates to a flow regulator for an ophthalmic phacoemulsification apparatus, belonging to the technical field of flow regulators. 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. Intraoperative flow control of the suction circuit plays an important role in the safety of the operation. At present, the phacoemulsification apparatus can be roughly divided into two commonly used working modes, 1. The working mode of the peristaltic pump, that is, the working mode in which the flow rate is fixed and the negative pressure can be adjusted. 2. Venturi pump working mode, that is, the working mode in which the flow rate and negative pressure rise and fall synchronously but the maximum flow rate is fixed. Both of these two existing working modes have unadjust...
