Problems solved by technology
[0004] Aiming at the deficiencies of the prior art, the present invention provides a phacoemulsification apparatus with replaceable treatment needles. The needles cannot be replaced in time, and there are no corresponding protection measures for the corresponding needles, and precise lifting cannot be performed during operation. When the device is adjusted accordingly, its position cannot be fixed accordingly, and when it is adjusted, it cannot produce corresponding support, which is easy to cause corresponding shaking problems

The invention belongs to the related technical field of cataract ultrasonic emulsification instruments, and particularly relates to a cataract ultrasonic emulsification instrument with a replaceable treatment needle, which comprises an emulsification instrument main supporting frame and a second fixing block, a base is arranged below the emulsification instrument main supporting frame, and a threaded mechanism is arranged in the emulsification instrument main supporting frame. A supporting mechanism is arranged on the outer wall of the emulsification instrument main supporting frame, the second fixing block is mounted above the outer wall of the emulsification instrument main supporting frame, a sliding block is arranged on the inner wall of the second fixing block, a second threaded rod is arranged above the outer wall of the second fixing block, and a second threaded groove is formed in the outer surface of the second threaded rod. According to the cataract ultrasonic emulsification instrument with a replaceable treatment needle, by arranging the threaded mechanism, the height of the emulsification instrument main supporting frame can be well and correspondingly adjusted, the height can be well adjusted and fixed through the adjustment, and the distance of a corresponding treated object can be conveniently adjusted.
Description
technical field [0001] The invention relates to the related technical field of cataract phacoemulsification apparatus, in particular to a cataract phacoemulsification apparatus with replaceable treatment needles. Background technique [0002] Cataract phacoemulsification is a technology that uses strong ultrasonic waves to crush the insoluble solids in the liquid into particles and fully mix them with the surrounding liquid to form an emulsion. The physical mechanism of crushing insoluble solids is generally considered to be ultrasonic cavitation effect. Phacoemulsification is currently in use in my country. Widely developed and popularized, it has become the mainstream method of cataract surgical treatment. In recent years, phacoemulsification has developed rapidly in terms of surgical techniques, surgical instruments and performance of phacoemulsification equipment, especially in terms of performance of phacoemulsification equipment. It is mainly the improvement of the energ...
