Description
Technical field
This utility model relates to a kind of medical apparatus and instruments evaluation apparatus, the adnexa that uses in the checkout gear of the ultrasonic performance indications of especially a kind of medical supersonic equipment, specifically a kind of transducer that can make is made two medical ultrasonic detection system transducer anchor clamps that degree of freedom rotates in horizontal plane and the vertical.
Background technology
As everyone knows, medical ultrasound is the application of ultrasonics in medical treatment, and according to its operation principle and characteristic, main application is divided into two big classes:
One, medical diagnosis is ultrasonic, mainly is to be applied to medical domain with the low-yield form of high frequency with diagnostic ultrasound promptly, is purpose to detect and to extract human body information, generally can not produce irreversible biological the variation in tissue.Because the medical diagnosis ultrasonic device is to be purpose to detect and to extract human body information, therefore in order to improve the definition of image, more accurate, the situation of response organization more clearly, the acoustical power of the equipment of ultrasonic diagnosis now is increasing, that have even arrived tissue is produced the biological degree that changes, especially particularly great to the influence of fetus, excessive ultransonic effect may cause the deformity of fetus.The clear picture of diagnostic ultrasound has become the main body of a pair of contradiction with biological effect, should guarantee safety, reach the clear of image again,, proposed the problem of the secure threshold of diagnostic ultrasound in the industry for the use ultrasonic diagnostic equipment that ensures safety for clinical diagnosis provides foundation.Must estimate the sound parameter of medical diagnostic equipment for this reason, guarantee the safety in the clinical practice.
Two, medical therapy is ultrasonic, and treating ultrasonic mainly is to act on human body with the high-octane form of low frequency (relative diagnosis is ultrasonic), makes tissue that certain take place and helps the disease treatment or the variation of physical rehabilitation.According to the difference of used ultrasound intensity, treat and ultrasonicly can be divided into again that physical therapy is ultrasonic, thermotherapy is ultrasonic and high intensity focused ultrasound (HIFU).In order to ensure human body, ultrasonic device also must operate in the secure threshold scope equally.
The design that medical supersonic sound field test macro in the market has three families such as ON-DATA, Sonora, Shanghai Communications University to be shaped, wherein ON-DATA, Sonora company have realized the marketization.
Medical supersonic sound field test macro mainly is made up of positioning measurment system, tank, data acquisition processing system, by positioning measurment system hydrophone and tested transducer are set up a space coordinate system in tank, data collecting system reads the signal of telecommunication of hydrophone gained, convert it to sound pressure signal and handle the sound field information that transducer sends of depicting, finally obtain the safe and effective property that parameters,acoustics such as needed acoustical power, mechanical index, heat number are estimated medical ultrasound equipment by date processing.
The used supersonic frequency of medical supersonic equipment obtains λ=c/f according to formula c=f* λ, wherein c=1500m/s in the water, so λ generally at 0.5MHz～20MHz
Min=1500/20M=75 μ m.For the space measurement trueness error of sound field, must be less than 1/10th of wavelength X when system's maximum operating frequency, so the certainty of measurement error should be higher than 7.5 μ m.This just requires the positioning accuracy of positioning measurment system will reach 7.5 μ m, and this requirement is very high.
What the location survey framework in the test macro of above-mentioned three companies design used all is metal frames such as rustless steel, aluminium alloy.
If measuring system vertical equity direction (X to) is 1200mm, press laboratory control temperature range and be ± 0.5 ℃ promptly 1 ℃, the coefficient of expansion that metal is minimum is 10 * 0.000001/ ℃, calculates δ L=L * α * δ t=1200 * 10 * 0.000001 * 1mm=0.012mm=12 μ m according to formula.This measured value in theory, laboratory temperature is controlled under the extraordinary situation still can not satisfy measurement requirement.In the real work, the environment of measuring system work is comparatively moist, big and difficult realization of thermostatic control ± 0.5 ℃ cost, and metal is perishable getting rusty in wet environment for a long time, accuracy and positioning accuracy for measuring system have been brought bigger influence, make the actual location precision of test macro of this kind framework can not be higher than 20 μ m.Do not reach the required precision of 7.5 μ m of standard-required.Therefore must adopt the low material of deflection as the work guide rail, to guarantee that simultaneously transducer keeps best transmission of angle with hydrophone all the time, and level and the interior rotational freedom guiding mechanism of vertical all are not set in the existing checkout equipment, this has influenced the raising of certainty of measurement to a certain extent.
Summary of the invention
The purpose of this utility model be at fail all in the existing medical ultrasonic detection system that transducer is provided with in the horizontal plane and vertical in the rotational freedom guiding mechanism and cause the bigger problem of measurement error, design a kind of medical ultrasonic detection system transducer anchor clamps that can do rotational freedom adjustment in level and the vertical simultaneously.
The technical solution of the utility model is:
A kind of medical ultrasonic detection system transducer anchor clamps, it is characterized in that it comprises that horizontally rotating drive rod and luffing angle adjusts drive rod, the upper end that horizontally rotates drive rod is inserted in the fixed block rotationally, the support of fixed block and detection system is fixedly linked, on fixed block, be installed with to make and horizontally rotate drive rod and be positioned at holding screw in the fixed block, luffing angle is adjusted drive rod and is positioned at a side that horizontally rotates drive rod by last brace and following brace, last brace is fixed on and horizontally rotates on the drive rod, following brace is fixed on the chuck, the upper end of chuck can telescopically be inserted in the lower end that horizontally rotates drive rod and by holding screw up and down and locate, the lower end of chuck is equipped with worm gear, worm gear is meshed with the worm screw that luffing angle is adjusted drive rod 152 lower ends, one end of upper clip and lower clamping piece is fixed on the worm-wheel shaft of worm gear, and their other end links to each other by connecting bolt.
The beneficial effects of the utility model:
This utility model is that transducer has increased in two faces totally four rotational freedoms, will improve the accuracy of the signal transmission between transducer and the hydrophone greatly, helps improving certainty of measurement, and is simultaneously easy to adjust.
This utility model also has simple in structure, and is easy to adjust, and reliable operation helps increasing the advantage that complete machine is adjusted degree of freedom.
