Embodiment

[0018] like figure 1 As shown, an ultrasonic lithotripter includes a stone crushing horn 1 and an ultrasonic transducer 2 threaded with the stone crushing horn 1, and the outer circumference of the ultrasonic transducer 2 is threaded with an operating handle 3 . The gravel horn 1 is a round rod with a taper, its taper α is 5°, the length of the gravel horn 1 is 300mm, and the diameter of the working surface of the gravel horn 1 is 3mm. A working channel 7 is arranged in the gravel horn 1, one end of the working channel 7 is set on the working surface 8 of the gravel horn 1, and the other end is connected with two channels. One of the channels is the suction channel 9, and the other channel is the water inlet channel 10. The suction channel 9 and the water inlet channel 10 are located in the hollow sleeve of the ultrasonic transducer 2, and the two channels are parallel to each other and have the same diameter (such as figure 2 shown). A bucket-shaped connecting cavity 11 ...

Abstract

The invention relates to a medical minimally invasive surgical tool, in particular to an ultrasonic lithotripper. It includes an ultrasonic transducer, the outer casing of the ultrasonic transducer is connected with the casing of the operating handle, the ultrasonic transducer is connected with a gravel horn, and a working channel is arranged inside the gravel horn, so One end of the working channel is set on the working surface of the gravel horn, and the other end is connected with two channels, one of which is a water inlet channel, and the water inlet channel is connected to the water inlet; the other is a suction channel, The suction channel is connected with the suction interface. The present invention mainly provides an ultrasonic lithotripter used in minimally invasive surgery and used in conjunction with an endoscope, which can completely absorb and crush stones, and then suck them out of the body through a pipeline without causing stones to enter the kidney internally, causing damage to the human body; solving the technical problem of incomplete external gravel in the prior art, which is likely to cause damage to the human body.

Description

technical field [0001] The invention relates to a medical minimally invasive surgical tool, in particular to an ultrasonic lithotripper. Background technique [0002] Because stones appear in the ureter, kidney, gallbladder and bladder in the human body, they have a great impact on people's health, and they often need to go to the hospital to crush and dissolve the stones in the body, thereby eliminating the pain of the human body. Existing lithotripsy generally adopts the method of extracorporeal shock wave lithotripsy. Mainly refers to ultrasonic lithotripsy in vitro. Such as the Chinese patent: "portable extracorporeal ultrasonic lithotripter" (CN1085415), which is made up of an ultrasonic detector and a transducer. The high-frequency peripheral low-frequency transducer in the hole is connected between the pulse generator and the preamplifier. The above-mentioned structure uses a detector to first find out where the stone is, and then crush it to cause the stone to dis...
