[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 attract intrauterine tissue

Embodiment Construction
[0030] The joint diagram illustrates how the phacoemulsification intrauterine tissue suction device works
[0031] Such as figure 1 As shown, the control system 11 sends instructions to the microcomputer processor 15 to turn on the cold light source 32 and the CCD imaging system 35 of the observation system 30, and the handle 20 is entered into the vagina through the observation system 30 that has been turned on, and the observation system 30 and The phacoemulsification needle 40 is delivered into the uterus. Since the internal environment of the uterus is difficult to see during pregnancy, the control system 11 sends instructions to the microprocessor 15 after entering the uterus to turn on the perfusion driver 122, and the perfusion driver 122 delivers the perfusion fluid 121 to the handle And output, so that you can clean the lens of the observation system and keep the lens clear to facilitate observation. At this time, bring the emulsification needle of the handle 20 close to...

The ultrasonic intrauterine tissue emulsifying and sucking apparatus for obstetric and gynecological operation includes a main unit, a handle and an observing system. It features that the ultrasonic emulsifying needle and the observing system are small enough to stretch the inside of the uterine and that the tissue inside the uterine is first ultrasonic emulsified and then extracted with the ultrasonic emulsifying needle. In addition a the observing system is provided with a temperature measuring system for the operator to regulate ultrasonic energy, perfused flow rate and extracting negative pressure conveniently to make the uterine inside always in constant temperature and liquid environment for safe and effective gynecological operation.
Description
Technical field [0001] The invention is an instrument used in the technical field of medical devices, especially a phacoemulsification device used for intrauterine tissue suction. Background technique [0002] Since its birth, phacoemulsification technology has a history of nearly forty years. It is usually used in phacoemulsification surgery for cataracts. Its technical principle is to convert electrical energy into mechanical energy through an ultrasonic generator and a transducer, and to drive extremely fine ultrafine ultrasonography. The nipple needle vibrates with low amplitude and high frequency, and transmits this vibration to the cataract that has been attracted by negative pressure to break it to a milky state, and then applies negative pressure to suction; in recent years, it has been reported that phacoemulsification technology has been applied to liposuction to lose weight. Phacoemulsification technology can be applied to other body parts except ophthalmology; however...
