Ultrasonic emulsification abortion unit

Abstract

The invention discloses an ultrasonic emulsification abortion unit comprising a base, a main part, an ultrasonic emulsification handpiece, an image acquisition system, an optical recognition system, a foot brake system and a sound system. The upper end of the main part is provided with an operating tabletop. The operating tabletop is provided with a display and operating buttons. The main part is further internally provided with an ultrasonic electric generator, a computer, a vacuum flow control system, a perfusion and suction system and an energy measuring system. The perfusion and suction system comprises perfusion liquid, a perfusion electromagnetic valve, a suction pump, a relief valve, a sensor and a waste liquid bag. The ultrasonic emulsification handpiece comprises an emulsification needle and a transducer. The optical recognition system comprises a key frame processor, a preprocessor, a target detector, an image processing module and an image light-dark color difference analysis module. The ultrasonic emulsification abortion unit has the advantages that neither uterine dilation nor uterine curettage is required, pain that an accepter experiences is greatly lightened, the use of an auxiliary foot brake leads to minimization of surgical risk, operating is facilitated, safety and reliability are ensured and surgical success rate is increased.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a ultrasonic emulsification abortion device. Background technique [0002] Phacoemulsification technology has a history of nearly 40 years since its birth. It is usually used in cataract phacoemulsification surgery. Its technical principle is to convert electrical energy into mechanical energy through ultrasonic The nipple tip vibrates at low amplitude and high frequency, and transmits this vibration to the cataract that has been attracted by negative pressure to break it into a milky shape, and then apply negative pressure to attract it; Phacoemulsification can be applied to other body parts except ophthalmology; however, there are no reports on the application of phacoemulsification to artificial termination of pregnancy. [0003] Applying phacoemulsification technology to artificial termination of pregnancy has its irreplaceable advantages. First, the emulsification ...
