Description
Technical field
This utility model belongs to medical supersonic therapeutic equipments field, relates to high intensity focused ultrasound and medical Type B ultrasonic detecting technology.
Background technology
High-strength focus supersonic therapeutic system is a kind of effective tumor therapeuticing method.This method produces hyperpyrexia by high-intensity focusing ultrasonic transducer in human body makes tumor tissues generation coagulation necrosis reach the purpose of oncotherapy.The ultrasonic transducer that is used for this therapy system need be made of a transducer and a B ultrasonic transducer that is used for the image guiding that produces high intensity focused ultrasound.Described focused transducer is placed on the lower end of water pocket or other water storage device, by pure water with the ultrasonic tissue that needs treatment that is coupled to.The transducer that common designed being used to produces focus supersonic is made of monolithic or array energy transducer, and puts into the B ultrasonic transducer at the center drilling of this transducer, is combined to form high-strength focused transducer.
The high-strength focused transducer that adopts monolithic transducer mode to constitute has comparatively simple structure, but machining accuracy is difficult to assurance, and can't adjust the incident direction and the burnt territory of sound wave.The focused transducer that adopts the array energy transducer mode to realize is that the multi-disc transducer is evenly distributed in sphere, all transducers are formed a powerful transducer after by connection in series-parallel, and by single control power drives generation high intensity focused ultrasound, but this structure can not realize the control to angle of incidence and burnt territory.
The centre bore of the B ultrasonic transducer directly being put into focused transducer is adopted in the combination of focused transducer and B ultrasonic transducer usually, adopts silica gel and O-ring to carry out waterproof sealing.This structure can satisfy the image guiding function, but the pure water as couplant can't be detected and control, and need add auxiliary device and make up.
Summary of the invention
Technical problem to be solved in the utility model is: provide a kind of array ultrasonic transducer that utilizes to realize incident direction and burnt territory shape adjustments, and can make up the high-intensity focusing ultrasonic transducer of B ultrasonic transducer and water channel realization image guiding and water level control.
This utility model solves the problems of the technologies described above the technical scheme that is adopted:
A kind of high-intensity focusing ultrasonic transducer, it comprises: transducer sheet, hemisphere face carriage, B ultrasonic transducer, sealing ring, water channel and pressure transducer.This high-intensity focusing ultrasonic transducer is a base unit with the small pieces transducer, and the arrangement mode of transducer sheet is divided into 6 districts by 60 ° to be arranged symmetrically, is bonded in the inboard of hemisphere face carriage, forms focused transducer.The variation of focus supersonic incident direction is realized respectively by independently driving power control in 6 zones by the power of adjusting the each several part power supply respectively; Power by adjusting driving power respectively and phase place realize the adjustment of the burnt territory of focus supersonic shape.Have three holes on the cylinder, centre bore is inlayed the B ultrasonic transducer, and a side opening is inlayed hydraulic pressure sensor, and another side opening is an osculum, is used to connect drain pipe, and using fixedly, swivel nut is fixed on cylinder in the centre bore of hemisphere face carriage.
The B ultrasonic transducer is positioned on the central axis of focused transducer, can observe a sector region that comprises the burnt territory of focused transducer, realizes the image guiding function.
Be embedded in the hydraulic pressure sensor in side opening of cylinder, be used to detect the water level that is positioned at focused transducer top water.The drain pipe that is connected in another side opening is used for water is discharged, by adjusting the adjustment of water yield size realization water level.
The beneficial effects of the utility model: this ultrasonic transducer can be realized incident direction and burnt territory shape adjustments, can make up B ultrasonic transducer and water channel and realize image guiding and water level control.
