Abstract
A multi-symmetrical high-intensity focused ultrasound transducer belongs to the technical field for medical ultrasound device, and comprises a transducer piece (101) positioned on a stand, an O-shaped seal ring (102), a semi-sphere stand (103), and a B-ultrasonic transducer (105). The transducer piece (101) positioned on the stand is divided equally into 4N parts arranged symmetrically in internal surface of semi-sphere stand (103) within 360-degree (N is a natural number), which forms an array of high intensity focused ultrasound transducer pieces. The array of high intensity focused ultrasound transducer pieces and the B-Ultrasonic transducer together form the high intensity focused ultrasound transducer. With the integrated structure, the semi-sphere stand (103) fixes easier and seals better. The ultrasound transducer can accurately adjust incidence direction and focal shape, avoid the asynchronous symmetry of focal shape relating to X axis and Y axis, and thus realize image guiding and waterline controlling by assembling B-ultrasonic transducer and water way.

High-strength focus supersonic therapeutic system is a kind of tumor therapeuticing method effectively.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 high-intensity focusing ultrasonic transducer that is used for this therapy system need be made of transducer sheet that produces high intensity focused ultrasound and the B ultrasonic transducer that is used for the image guiding.Described high-intensity focusing ultrasonic transducer is placed on the lower end of water pocket or other water storage devices, by pure water with the ultrasonic tissue that needs treatment that is coupled to.The transducer that common designed being used to produces high intensity focused ultrasound is made of the transducer chip arrays, and put into the B ultrasonic transducer at this transducer chip arrays center drilling that can produce high intensity focused ultrasound, both common combinations are formed for the high-intensity focusing ultrasonic transducer of this therapy system.
The high-intensity focusing ultrasonic transducer that adopts transducer chip arrays mode to realize is that multi-disc transducer sheet is arranged in sphere, all transducer sheets are formed a powerful high-intensity focusing ultrasonic transducer chip arrays 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 high intensity focused ultrasound angle of incidence and burnt territory.The high-intensity focusing ultrasonic transducer that adopts transducer chip arrays piecemeal arrangement mode to realize is the multi-disc transducer is arranged in sphere and to be divided into several zones, each zone produces high intensity focused ultrasound by single control power drives, and all zones form a powerful high-intensity focusing ultrasonic transducer array.But since the zone between about X-axis and Y-axis simultaneously the symmetry, though can adjust, can't accurately control incident direction and burnt territory, symmetry when can't make burnt territory about X-axis and Y-axis to the incident direction and the burnt territory of sound wave.
The centre bore of the B ultrasonic transducer directly being put into the high-intensity focusing ultrasonic transducer chip arrays is adopted in the combination of high-intensity focusing ultrasonic transducer chip arrays and B ultrasonic transducer usually, adopts silica gel and O-ring to carry out waterproof sealing with the fastening back of screw.Utilize the structure of O-ring and silica gel sealing can satisfy the image guiding function again behind this centre bore that the B ultrasonic transducer is fastened to the high-intensity focusing ultrasonic transducer chip arrays with screw, but because complex structure own, assemble products from parts are more, and sealing property is not good.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of accurate adjustment that utilizes symmetrical expression ultrasonic transducer chip arrays to realize incident direction and burnt territory shape is provided, and can makes up the high-intensity focusing ultrasonic transducer of B ultrasonic transducer and osculum realization image guiding and water level control.
This utility model solves the problems of the technologies described above the technical scheme that is adopted:
The sectional polynary high-intensity focusing ultrasonic transducer of a kind of symmetry, it comprises: be fixed on transducer sheet, hemisphere face carriage, B ultrasonic transducer, O RunddichtringO on the support, osculum, the O RunddichtringO is used for the sealing between high-intensity focusing ultrasonic transducer and the water pocket, the transducer sheet that is fixed on the support is divided into 4N subregion in 360 °, arrange and be fixed on the inner surface of hemisphere face carriage symmetrically, N is a natural number, 1～100 transducer sheet that is fixed on the support is placed in each zone, and transducer sheet diameter is 1～50MM; All subregions form the high-intensity focusing ultrasonic transducer chip arrays jointly, and each subregion is respectively by the control of power supply independently, the adjustment that power by adjusting driving power respectively and phase place realize burnt territory shape of focus supersonic and incident direction; The B ultrasonic transducer directly is embedded in hemisphere face carriage center; The transducer chip arrays sealing and fixing that the use bonding agent can produce high intensity focused ultrasound is on the hemisphere face carriage, and the transducer chip arrays and the B ultrasonic transducer combinations that can produce high intensity focused ultrasound form high-intensity focusing ultrasonic transducer jointly.
The hemisphere face carriage adopts integral structure, and an oblong aperture is opened at the center of hemisphere face carriage, in inlay the B ultrasonic transducer, it is osculum that oblong aperture one side or opposite side have a circular hole, in screw thread is arranged, be used to connect drain pipe.
The outer shroud of the inner surface of hemisphere face carriage is opened an annular waterproof sealing groove, and the outer shroud of central boss upper surface is opened an annular waterproof sealing groove.
The B ultrasonic transducer is positioned on the central axis of hemisphere face carriage, can observe a sector region that comprises the burnt territory of high-intensity focusing ultrasonic transducer chip arrays, realizes the image guiding function.
The beneficial effects of the utility model: this high-intensity focusing ultrasonic transducer can be realized the accurate adjustment of incident direction and burnt territory shape.B ultrasonic transducer and water channel be can make up and image guiding and water level control realized.Integrated hemisphere face carriage is the transducer sheet and the B ultrasonic transducer of mounting strap support directly, be more convenient for sealing and installation.On integrated hemisphere face, adopt the waterproof sealing groove to make waterproof effect outstanding.
