Detailed description of the invention
Below in conjunction with Figure of description, the invention will be further described:
High frequency ultrasonography probe directly swept by machinery, comprise probing shell 1, the sound passing membrane 2 be connected with probing shell, transducer 3, transducer drive mechanism, power drive mechanism and drive motors is provided with in probing shell, drive motors drives power drive mechanism to drive transducer drive mechanism kinematic, and then drives transducer motion; Transducer 3 adopts first transducer that singly shakes, and its haul distance is not less than 30mm(ultrasonic examination length), frame frequency is 5-8 frame, and drive motors 8 adopts 25BC320 motor, and meet the use section 600Hz-960Hz that it involves characteristic, step angle is 3 °; Transducer drive mechanism is by the long helical pitch screw mandrel of bull screw mandrel 5() and feed screw nut 4 coordinate form, the helical pitch of bull screw mandrel 5 is 15mm, namely when bull screw mandrel 5 run two coil transducers run strokes be 30mm, bull screw mandrel inverted running 2 encloses, transducer 3 inverted running 30mm, complete a frame motion, feed screw nut 4 is equipped with transducer 3, bull screw mandrel drives transducer transverse movement to realize directly sweeping; For meeting the demand involving characteristic of motor, power drive mechanism adopts gear speed increasing mechanism, namely the driving gear 6 arranged by engagement and driven gear 7 are formed, driving gear 6 is arranged on the outfan of drive motors, driven gear 7 is arranged on one end of bull screw mandrel, and drive motors coordinates driving bull screw mandrel to rotate by driving gear and driven gear.
Carrier base 9 is also provided with in probing shell of the present invention, carrier base is fixedly installed and visits core support 10, bull screw mandrel and drive motors are all arranged on by bearing 11 to be visited in core support, and bull screw mandrel and drive motors are provided with bearing block 12(movable sealing) and adjust gap nut 13.
In order to ensure the service life of transducer signal lead-out wire 14, adopt helical coil signal lead-out wire, can extended line length, reduce the mode of line movement angle.
Example: design supersonic frequency be 15,000,000 high frequency directly sweep probe
1. be example with 15,000,000 high-frequency transducers, its running frequency is 5 frames;
2. bull screw mandrel (the long helical pitch screw mandrel) helical pitch of transducer is 15mm, namely when bull screw mandrel run two coil transducers run strokes be 30mm, bull screw mandrel inverted running 2 encloses, transducer inverted running 30mm, complete a frame motion, according to ultra sonic imaging needs, transducer must complete the speed of service of 5 frames/second, can calculate the bull screw mandrel speed of service is 2 × 2 × 5=20 revolutions per second (positive 10 turns, anti-10 turns);
3. the gear ratio of gear speed increasing mechanism driving gear and driven gear is set to 4:1, driving gear rotating speed is 20 ÷ 4=5 revolutions per second;
4. driving gear is directly installed on drive motors, and therefore the rotating speed of driving gear is the rotating speed of drive motors;
5. calculate motor (drive motors) output frequency (involving characteristic by motor to limit)
5×360°÷3°=600HZ
Motor adopts three-phase six-beat, and namely step angle is 3 °.
From above-mentioned example, different frequency transducer is selected namely to can be made into different frequency probe according to different clinical requirement; Change drive motors output frequency, different frame frequency image can be obtained, with the medical needs of satisfied difference.
Example: when drive motors output frequency is 720Hz, obtain 6 two field pictures; When drive motors output frequency is 840Hz, obtain 7 two field pictures; When drive motors output frequency is 960Hz, obtain 8 two field pictures.
Therefore drive motors employing 25BC320 motor is given prominence to and is met the use section 600Hz-960Hz that it involves characteristic.
