Abstract
The utility model discloses a hydrophone adjusting device for the sound field measurement of high intensity focused ultrasound, and relates to a medical ultrasonic therapeutic instrument. The device has the following connection structure: a pressure sensor (11) is embedded in a tube at the lower end of a hollow catheter (8); a signal wire (6) penetrates through the hollow catheter (8) and is connected with the pressure sensor (11); the lower end of the hollow catheter (8) penetrates through a small hole at the center of a double-layer horizontal table; straight rods (2) are axisymmetrically fixed on two sides of a fixed supporting table (1) through tube clamps (7); the lower parts of the straight rods are in threaded connection with upper universal joints (3); the upper universal joints (3) are connected with lower universal joints (4) through cross shafts; the lower universal joints (4) are welded on a horizontal shim plate (9); and a table group (5) with two angular positions is connected with the fixed supporting table (1) through screws. By adjusting the table group (5) with two angular positions to drive the hollow catheter (8) to rotate, the sensing surface of the pressure sensor (11) keeps parallel to the horizontal plane, so that sound field measurement is more accurate.
Description
Technical field
This utility model relates to medical supersonic therapeutic equipments field, is specially adapted to the high intensity focused ultrasound acoustic field.
Background technology
In high strength supersonic acoustic field process, the lamellar voltage sensitive sensor is fixed on the probe holder, moves and monitor change of sound field by three-dimensional movement governor control probe in measurement plane.
The effect that is used for the probe holder of this device is to guarantee that lamellar voltage sensitive sensor normal direction is vertical with the measurement horizontal plane of tank as far as possible.And in the actual installation process, can not guarantee that lamellar voltage sensitive sensor normal direction is vertical fully with the measurement horizontal plane, and in a single day install and finish just can not adjust.This just certainly will cause the sound field of surveying inaccurate, thereby the problem that causes focusing accuracy in the actual therapeutic process to descend.
Summary of the invention
Technical problem to be solved in the utility model is: a kind of secured adjusted device of lamellar voltage sensitive sensor is provided, makes lamellar voltage sensitive sensor normal direction accurately to adjust, thereby make it vertical fully with the measurement horizontal plane.
The technical scheme that its technical problem that solves this utility model adopts is:
The hydrophone adjusting device that is used for the high intensity focused ultrasound acoustic field, it is formed by connecting with the bonding double-layer horizontal platform of forming of universal joint, horizontal backing plate and abatvoix that lower cardan connects to form by pressure transducer, hollow tubing conductor, stationary gantry, position, two angle platform group, straight-bar, upper cardan (3).
Pressure transducer is embedded in the pipe of hollow tubing conductor lower end, and holding wire passes hollow tubing conductor and is connected with pressure transducer;
The aperture of double-layer horizontal platform central authorities and straight-bar are passed with on axisymmetric two sides that are fixed on stationary gantry of pipe clamp in the lower end of hollow tubing conductor, make pressure transducer contact with the water surface.
The straight-bar bottom is provided with screw thread, is screwed in the screwed hole of upper cardan;
Upper cardan is connected by cross axle with lower cardan;
Lower cardan is welded on the horizontal backing plate;
Position, two angle platform group is connected with screw with stationary gantry;
Drive the hollow tubing conductor rotation by regulating two positions, angle platform group, make the sensitive surface of pressure transducer keep parallel with horizontal plane.
Horizontal backing plate is made by metal, and abatvoix is made by rock cotton board.
Position, two angle platform group by angle of regulation range ± 10 °, least count be 5 ' position, two angles platform form.
The function that said structure is finished is: when the circular section of its induction planes and hollow tubing conductor is not parallel in the time of in pressure transducer is being packed hollow tubing conductor into, just can make the induction planes of pressure transducer parallel fully by regulating position, two angles platform with floating platform, and floating platform is parallel to the water surface, and the induction planes of pressure transducer just can be parallel to the water surface fully like this.
The beneficial effects of the utility model are: can adjust the pressure transducer normal direction easily, accurately by the combination of position, high accuracy angle platform, make it vertical with horizontal plane, make that finally acoustic field is more accurate.
