Three-dimensional mechanical ultrasonic probe
View Patent ↗A three-dimensional mechanical ultrasound probe includes a base; a transducer for emitting an ultrasonic signal; a driven wheel with a hole, the driven wheel being connected to the transducer, the transducer being swung by the driven wheel; a motor fixed on the base; and a transmission system connected to the motor and a first rope, the transmission system being driven by the motor, the first rope being driven by the transmission system, wherein the first rope is connected to the transmission system and a rope adjusting dowel; and wherein the adjusting dowel is pivotably inserted into the hole of the driven wheel.
1. A three-dimensional mechanical ultrasonic probe, comprising:
a base;
a transducer for emitting an ultrasonic signal;
a driven wheel connected to the transducer, an orientation of the transducer being controlled by the driven wheel;
a motor fixed on the base;
a transmission system connected to the motor and a first rope, the transmission system being driven by the motor, the first rope driving the driven wheel and being driven by the transmission system; and
a rope adjusting dowel for adjusting an effective length of the first rope.
2. A three-dimensional mechanical ultrasonic probe according to claim 1 , wherein the driven wheel includes two concentric holes, the rope adjusting dowel positioned in the two concentric holes, and wherein the rope adjusting dowel can rotate in the two concentric holes.
3. . A three-dimensional mechanical ultrasonic probe according to claim 1 , wherein the rope adjusting dowel includes a through-hole, the first rope connected to the rope adjusting dowel through the through-hole.
4. A three-dimensional mechanical ultrasonic probe according to claim 1 , further comprising a nut, the nut coupled to the rope adjusting dowel, wherein a direction of tightening a screw joint by rotating the rope adjusting dowel relative to the nut is the same as a rotating tendency direction of the rope adjusting dowel under an action of a pull of the rope.
5. A three-dimensional ultrasonic probe according to claim 1 , wherein the transmission system includes a driving timing pulley, a driven timing pulley and a driving shaft, the driving timing pulley connecting with an output of the motor and driving the driven timing pulley by a timing belt, wherein the driven timing pulley drives the driving shaft connected to the first rope.
6. A three-dimensional ultrasonic probe according to claim 1 , further comprising a second rope, one end of the second rope connected with the transmission system, wherein the driven wheel includes a spring connected with another end of the second rope.
7. A three-dimensional ultrasonic probe according to claim 1 , wherein the rope adjusting dowel adjusts the effective length of the first rope by adjusting a length of a portion of the first rope wound onto the rope adjusting dowel.
8. A three-dimensional ultrasonic probe according to claim 7 , wherein one end of the first rope is connected to the rope adjusting dowel.
9. A three-dimensional ultrasonic probe according to claim 8 , wherein the rope adjusting dowel is rotated to cause a portion of the end of the first rope connected to the rope adjusting dowel to be wound onto or unwound from the rope adjusting dowel to adjust the effective length of the first rope.
