Extra chock wave lithotriptor Ultrasonic-B probe positioning regulating mechanism
Technical field
This utility model relates to medical apparatus and instruments, particularly a kind of extra chock wave lithotriptor Ultrasonic-B probe positioning regulating mechanism.
Background technology
Extra chock wave lithotriptor is a kind of a kind of medical apparatus and instruments for the treatment of the human body calculus of urinary system.It is to utilize electrion to produce shock wave by reflecting the cylinder convergence, and conduction arrives stone location and calculus generation impact is reached crushed stone, and then the purpose that excretes through liquid medium (comprising water and the intravital body fluid of people in the reflection cylinder).And how to come to determine the calculus position in the human body and calculus moved to the rubble point, be that can lithotrite successful, the effective key of treatment, therefore, the navigation system of lithotrite is just particularly important.At present, both at home and abroad the locate mode of lithotrite has X-ray location and B ultrasonic to locate dual mode, X-ray locate mode comparative maturity wherein, and basic structure is with common fluoroscopic machine, and digital stomach and intestine machines etc. are similar.B ultrasonic is located then relative complex, and because of the limitation of B ultrasonic location itself, position fixing process must contact with human body, and motility is not high, and therefore the B ultrasonic positioner of each manufacturer has nothing in common with each other and all has certain limitation at present.
Summary of the invention
The purpose of this utility model is to provide a kind of extra chock wave lithotriptor Ultrasonic-B probe positioning regulating mechanism, be provided with reflection cylinder and location focal adjustment device, make Ultrasonic-B probe can carry out the adjustment of all degree of freedom, make the doctor survey calculus easily, improve therapeutic effect around axle.
For reaching above-mentioned purpose, this utility model is made up of reflection cylinder, location focal adjustment device and Ultrasonic-B probe; The outside of reflection cylinder is with the cylinder flange, and cylinder flange and carrier base one end are affixed by screw, and the end in addition of carrier base is connected with screw by the jack rod sleeve of connecting axle with location focal adjustment device, and the end in addition of location focal adjustment device is equipped with Ultrasonic-B probe.
The jack rod sleeve of described location focal adjustment device one end is connected with carrier base by connecting axle, and jack rod sleeve can be regulated high and low angle around the connecting axle rotation of carrier base; Slide bar interts in jack rod sleeve, be carved with scale on the slide bar, slide bar can telescopic moving in jack rod sleeve, adjusts length, and lock with check lock lever, the end in addition of slide bar is equipped with adapter sleeve, and the end in addition of adapter sleeve is fitted with turning handle, and turning handle can be at the adapter sleeve internal rotation, corner adjustable, tighten up the location with dog screw, clamping plate are housed on the turning handle, clamping plate are clamped Ultrasonic-B probe.
Superior effect of the present utility model is:
1, simple in structure, controllability is strong-adopt fabricated structure, but coupling part flexible support level, upright position makes Ultrasonic-B probe can carry out the adjustment of all degree of freedom, directed toward focal point better around axle.
2, removable adjustable range indicates graduated slide bar displacement and reaches 120mm, can adapt to the calculus location of different parts.
3, the B ultrasonic support can horizontally rotate about 270 degree around the reflection cylinder, and makes Ultrasonic-B probe point to second focus, satisfies different patients ' demands.
