The built-in B ultrasonic positioner of the wave source of extra chock wave lithotriptor
Technical field
This utility model relates to a kind of extra chock wave lithotriptor, refers specifically to a kind of built-in B ultrasonic positioner of wave source of extra chock wave lithotriptor.
Background technology
Extra chock wave lithotriptor is to utilize electrohydraulic effect (in the pulsed discharge of water mesohigh) or the galvanomagnetic-effect high pressure pulse discharge of coil (in the water by) effect to produce shock wave, after focusing on, produce the stress area of high concentration at the focus place, when calculus is positioned at this Jiao district, because calculus and water and human body soft tissue shock wave resistance difference are very big, will on calculus, produce the compressive stress and the tensile stress of certain intensity, and water and human body's soft tissue is approximate, shock wave is lossless substantially to be passed through, behind hundreds of discharge impacts about time to 2,000 times, calculus is crushed to excretes external fineness, and reach the purpose of treatment.So the rubble location of lithotrite calculus is an important link, the location has X line location and two kinds of methods of localization by ultrasonic usually, and this utility model relates to ultrasound locating method.
The localization by ultrasonic of present most of lithotrites is mounted in outside the surge generator, what become a fixed angle with generator can make the flexible machinery of probe, when the probe of the device of this structure is sought calculus on patient body, because the center probe extended line need pass through focus all the time, therefore the ultrasonic incident angle of probe generally can only be about 45 °, if make wave source change angle, usually also can only accomplish about 70 °, like this, will seek calculus to the doctor and increase difficulty, because in most cases, ultrasound wave vertically enters from skin, be the optimal path of surveying, this is the general knowledge of sonographer, so this defective of external B ultrasonic positioner is unavoidable.
The utility model content
The purpose of this utility model is to provide a kind of built-in B ultrasonic positioner of wave source of extra chock wave lithotriptor, and it can make ultrasound wave vertically enter from skin, reaches the optimal path of surveying calculus.
In order to achieve the above object, this utility model is realized by following technical scheme.
The built-in B ultrasonic positioner of a kind of wave source of extra chock wave lithotriptor comprises reflector, electromagnetic impact wave source and Ultrasonic-B probe, and the electromagnetic impact wave source is located in the reflector, it is characterized in that: described Ultrasonic-B probe is vertically installed in the electromagnetic impact wave source.
This utility model beneficial effect is, Ultrasonic-B probe is vertical in the electromagnetic impact wave source, has changed traditional localization by ultrasonic and has been mounted in outside the surge generator, and it can make ultrasound wave vertically enter from skin, reaches the optimal path of surveying calculus.
