Abstract
The invention concerns an ultrasonic treatment feeler belonging to the biomedical treatment technology field. The feeler is made up of an ultrasonic transducer piece(2) plastered to the insulation layer(1), wirings(3), sound absorption materials(4), joints built in the inner wall of the feeler(5), a sound conducting liquid medium installed in the liquid filled hole(7), liquid filled holes(7) and gas exhaust holes(8) installed in the outer wall of the feeler, a soft acoustic permeable membrane installed in the top of the feeler(9). The invention has simple structure and convenient operation, being capable of improving the coupling efficiency between the feeler and the patients in a large extent, increasing the uniformity of the sound intensity of the target region and balancing the sound pressure of all sites.
Description
Technical field:
The present invention relates to a kind of ultrasonic therapeutic probe, belong to ultrasound biological therapeutic treatment technical field with compliant interface.
Background technology:
Sonicator mainly is made up of ultrasonic transmitter and probe, and the former is made up of the higher-order of oscillation and power circuit, and utilization " reciprocal piezoelectric effect " principle acts on transducer in the probe with high-frequency electric field, makes the vibration of its generation corresponding frequencies.Thereby convert electrical energy into mechanical energy with the sound field performance.Existing ultrasonic therapeutic instrument probe plane (or curved surface) commonly used normal probe.Comprise ultrasound transducer element and other accessory of transmitting and receiving ultrasonic energy.Element of transducer is generally circle, semicircle or rectangle.In all or part of probe of packing into of emission ultrasound unit circuit.The probe interface is the material of hard or immutable its geometry.
Ultrasonic signal transmission speed in different medium is different, and its attenuation degree is also different, is generally the assurance therapeutic effect, and probe is smeared ultrasonic coupling mediating recipe with the contact surface of therapentic part makes its tight contact.For making the emission sound field even, also between piezoelectric chip and probe interface, be full of the sound-guiding liquid body medium and solve emission sound field skewness, the too high problem of centre acoustic pressure in addition.But still do not solve owing to the therapentic part difference, patient's individual variation causes being controlled position sound field skewness, and the unbalanced problem of each position acoustic pressure causes to cause scald or twinge in therapeutic process.
By literature search, do not find the relevant open report identical with technical solution of the present invention.
Summary of the invention:
The objective of the invention is to overcome the deficiency of prior art, and a kind of ultrasonic therapeutic probe with compliant interface is provided.
Structure of the present invention is: this probe by stick on ultrasonic transducer sheet (2), wiring (3), sound-absorbing material (4) on the sealing coat (1), place joint (5) on the inner probe wall, place topping up hole (7) sound-guiding liquid body medium (6), place topping up hole (7) and steam vent (8) on the probe outer wall, place the flexible sound passing membrane (9) of probe tip to form.The ultrasonic signal of telecommunication arrives ultrasonic transducer sheet (2) from joint (5) by wiring (3) and is converted to acoustic field signal, passes the coupling of sealing coat and launches equably with the flexible sound passing membrane (9) that contacts with the patient from sound-guiding liquid body medium (6).The effect of sound-absorbing material (4) is the vibration damping that increases wafer, and the ultrasound wave that send at the back side of absorption piezoelectric chip improves the ultransonic efficient of emission.
Flexible sound passing membrane (9) be with making with the flexible material that liquid changes how much interface shapes, and flexible material is for having certain intensity, not cracky and aged material.As rubber membrane, plastic foil, polymer material film, biological manufactured goods film etc.The thickness of flexible sound passing membrane (9) is 1/4 wavelength of tranmitting frequency.Sealing coat (1) thickness of pasting the transducer sheet also is 1/4 wavelength of tranmitting frequency.For the de aerated water that guarantees filling is emptied completely, topping up hole (7) are a little less than steam vent (8).
Advantage such as that the present invention has is simple in structure, easy and simple to handle, effect is obvious.Can improve probe and patient's coupling efficiency greatly.Improve and controlled uniformity and balanced each position acoustic pressure that the position sound intensity distributes.
Description of drawings:
Accompanying drawing 1 is structural representation of the present invention.
The specific embodiment:
This ultrasonic therapeutic probe with compliant interface is assembled by the part of being narrated in the foregoing invention content.Mode of operation is: open topping up hole (7) and steam vent (8), be full of and vent gas the capping of covering tight topping up hole (7) and steam vent (8) from topping up hole (7) filling de aerated water (the little fire of 500 ml tap waters boiled 15 minutes, cooled, and did not stir); Opening power is provided with the treatment time and the sound intensity subsequently, and the need therapentic part is kept moist or coats couplant, need closely contact and can treat with flexible sound passing membrane (9) by therapentic part.Can adjust the sound intensity in the therapeutic process.
Claims (1)
1, a kind of ultrasonic therapeutic probe with compliant interface, it is characterized in that this probe by stick on ultrasonic transducer sheet (2), wiring (3), sound-absorbing material (4) on the sealing coat (1), place joint (5) on the inner probe wall, place topping up hole (7) sound-guiding liquid body medium (6), place topping up hole (7) and steam vent (8) on the probe outer wall, place the flexible sound passing membrane (9) of probe tip to form.
