Abstract
An insert section of an ultrasonic probe device which is bendably coupled by means of a hinge with two rotation shafts rotatably disposed within an insert section that is coupled to a universal joint. The distal tube can be bent freely by operating a control knob at a control section, so that an ultrasonic transducer member at the tip of the distal tube may be brought closely into contact with the body wall.
Claims7
An ultrasonic diagnostic apparatus comprising:
- an insert section including at least a rigid base tube and a rigid distal tube bendably coupled with each other by at least one hinge means, first and second rotation shafts rotatably disposed in said rigid base and distal tubes respectively and coupled with each other by at least one universal joint, and ultrasonic transducer means including an ultrasonic scanning member disposed at the distal end of said rigid distal tube and attached to the distal end of said second rotation shaft;
- and
- a control section including a rotation driving source for supplying rotation driving force to said first and second rotation shafts and a bending drive means for driving said distal tube to bend.
An ultrasonic diagnostic apparatus comprising:
- an ultrasonic probe device constituted by an insert section including at least a rigid base tube and a rigid distal tube bendably coupled with each other by at least one hinge means, first and second rotation shafts rotatably disposed in said rigid base and distal tubes respectively and coupled with each other by at least one universal joint, and ultrasonic transducer means including a plurality of ultrasonic transducers disposed at the distal end of said rigid distal tube and attached to the distal end of said second rotation shaft;
- and a control section including a rotation driving source for supplying rotation driving force to said first and second rotation shafts to rotate said ultrasonic transducers, a bending drive means for driving said rigid distal tube to bend, and a rotation angle detector for detecting the rotation angle of said rotation driving source;
- and
- an observation device including a signal transmitter-receiver means connected to said ultrasonic probe device, whereby driving pulses are supplied to said ultrasonic transducer means and echo signals are received, and a display means for indicating a slice image corresponding to the echo signals from said signal transmitter-receiver means.
