Abstract

The invention discloses a flow regulator for an ophthalmological ultrasound emulsification instrument. The flow regulator comprises a connecting box body, wherein a filter screen is welded in the central portions of the upper end and lower end of the inner portion of the connecting box body, an outlet is formed in the center of the upper end of the connecting box body, the upper end of the outletis welded with a connecting duct, a liquid outlet pipe is arranged above the connecting duct, the outer side of the lower end of the liquid outlet pipe and the outer side of the upper end of the connecting duct are both provided with a set of connecting rings, a liquid can be introduced into the connecting box body through a liquid inlet duct, the filter screen in the connecting box body can filter the liquid, the rotation of an adjusting pipe can drive a rotational adjusting plate to rotate, and the rotation of the rotational adjusting plate can stagger through holes in the rotational adjusting plate with through holes in a fixed adjusting plate so as to adjust the size of the through holes. The flow regulator for the ophthalmological ultrasound emulsification instrument has the advantages that the structure is simple, not only can the liquid be filtered, but also the flow adjustment is more convenient, thereby providing convenience for a doctor.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a flow regulator for an ophthalmic phacoemulsification apparatus. Background technique [0002] Phacoemulsification is the main surgical method for cataract treatment at present. The phacoemulsification instrument is the key surgical equipment for phacoemulsification. The flow control of the suction line during the operation plays an important role in the safety of the operation. The working mode of the existing phacoemulsification apparatus has the disadvantage that the flow parameters cannot be adjusted, which has a great impact on the safety of the operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the existing defects and provide a flow regulator for ophthalmic phacoemulsification apparatus, which is simple in structure and easy to operate, not only can filter the liquid, but also makes it more co...
