The invention content is as follows:

aiming at the defects, the invention provides ultrasonic prostate operation equipment.

The invention relates to ultrasonic prostate surgery equipment, which is characterized in that: the ultrasonic excision knife is characterized by comprising an ultrasonic excision knife, a transducer and an ultrasonic host, wherein the front part of the ultrasonic excision knife is columnar, the rear end of the ultrasonic excision knife is connected with the transducer, the transducer is communicated with the ultrasonic host through a cable, and the ultrasonic excision knife is guided into an affected part with prostatosis of a patient through a guide tube inserted into the urethra of the patient.

Further, the output frequency of the transducer is 55 +/-5 kHz.

Furthermore, the handle part convenient for an operator to hold is arranged on the ultrasonic scalpel, the handle part comprises a first handle part and a second handle part which are perpendicular to the ultrasonic scalpel, a first hole is formed in the first handle part, a second hole is formed in the second handle part, and the first hole and the second hole facilitate the penetration of fingers of the operator.

Further, the guide pipe is a metal pipe or a plastic pipe.

Furthermore, the guide tube and the ultrasonic scalpel have the same cross section and are in clearance fit, and the inner peripheral wall surface of the guide tube or the surface of the ultrasonic scalpel is provided with threads.

The working method of the ultrasonic prostate surgical equipment comprises the steps that the front part of the ultrasonic excision knife is columnar, the rear end of the ultrasonic excision knife is connected with the transducer, the transducer is communicated with the ultrasonic main machine through a cable, and the ultrasonic excision knife is guided into an affected part of a prostate disease of a patient through a guide tube inserted into the urethra of the patient; before work, the transducer and the ultrasonic main machine are connected through a cable, when the ultrasonic surgical instrument works, a guide tube is penetrated into the urethra of the prostate of a patient, and then an operator holds the ultrasonic excision knife to extend into the guide tube until the end of the ultrasonic excision knife touches the affected part.
