Benefits of technology

[0006] According to one aspect of the present invention, there is provided an ultrasonic apparatus diagnostic, an ultrasonic probe, a puncture guide and a method for detecting the angle of a puncture needle that does not require an operator to perform a bothersome operation for display of a puncture guide image.

Problems solved by technology

This is complicated for the operator.
On the other hand, in the case that another cable is connected to the apparatus body, the increasing number of cables adversely impact operability, and providing a new connecter for puncture is needed.
However, in the above mentioned case, use of the sensor makes the structure complicated, makes disinfection or sterilization of the guide difficult, and makes the guide too expensive to be disposable.

first exemplary embodiment

(First Exemplary Embodiment)

[0018] An ultrasonic probe 10 shown in FIG. 1 (b) includes a probe body 11 holding an ultrasonic transmit and receiving unit 12 having arrayed ultrasonic transducers, and an alternating photo sensor 13 including luminous elements 13a and light sensitive elements 13b. Lead wires of the luminous elements 13a and the light sensitive elements 13b are wired in a probe body 11. The wires are connected to a body of the ultrasonic diagnostic apparatus through a probe cable 11c with read wires of ultrasonic transducers.

[0019] As a slide opening part 22 of puncture adaptor 20 shown in FIG. 1 (a) is positioned opposite the photo sensor 13 of the probe body 11, a holder 21 of the puncture adaptor 20 holds the probe body 11, as shown in FIG. 1(c). A slider 23, having a reflective face facing the probe body 11, is fitted into a slide opening part 22 of the puncture adaptor 20, and a needle guide 24 is fastened at one end of the slider 23 by screws (not shown) to the s...

second exemplary embodiment

(Second Exemplary Embodiment)

[0030] In a second embodiment, as shown by FIG. 3, it is characteristic that a pattern having different degrees of reflection, for example a black and white stripe pattern, is provided on a probe body side of the slider 26. The pattern is detected by one pair of a luminance element 15a and a sensitive element 15b provided on the probe body 11. In the explanation of this exemplary embodiment, explanations of similarities with the first exemplary embodiment will be skipped, and differences will be mainly explained.

[0031] In this second exemplary embodiment, the needle guide 24 of the puncture adaptor 20 held by the probe body 11a of the ultrasonic probe 10a is moved to a desirable position. By this movement, when the stripe pattern on the slider 26 passes by the luminance element 15a and the sensitive element 15b, the sensitive element 15b receives reflected light from the luminance element intermittently. A read wire for light receiving signals is provid...

third exemplary embodiment

(Third Exemplary Embodiment)

[0037] In a third exemplary embodiment as shown by FIG. 4, a magnetized magnetic element 27a is provided on the probe body side of the slider 27 and a magnetic sensor unit formed by magneto metric sensors 16a-16f is provided at the probe body 11b in a circular direction. In the explanation of this exemplary embodiment, explanation of similarities with the first exemplary embodiment will be skipped, and differences will be mainly explained.

[0038] In this exemplary embodiment, the needle guide 24 of the puncture adaptor 20 held by the probe body 11b of the ultrasonic probe 10b is moved to a desirable position. By this movement, when the magnetic element 27a on the slider 27 passes past the magneto metric sensors 16a-16f, the magnetic metric sensors 16a-16f detect the passing of the magnetic element 27a in turn. A read wire for detecting signals is provided in the probe body 11a and the probe cable, and the signal is delivered to the sensor IF unit 34. When...

Abstract

An ultrasound diagnostic apparatus including an ultrasonic probe transmitting and receiving ultrasound toward and from a subject, a puncture adaptor configured to be fixed to the ultrasonic probe and to hold a puncture needle, wherein the puncture adaptor has moving part movable in relation to the ultrasonic probe with the puncture needle, and a sensor provided at the ultrasonic probe, and configured to detect the position of the moving part. As the puncture needle is moved relative to the probe, the movable part is correspondingly moved relative to the probe, and movement of the movable part, and therefore also of the puncture needle, is detected by the sensor.

Description

CROSS REFERENCE TO RELATED APPLICATIONS [0001] This application is based upon and claims the benefit of priority from the prior Japanese Patent Application No. 2005-233308, filed on Aug. 11 2005, the entire contents of which are incorporated herein by reference. BACKGROUND OF THE INVENTION [0002] An ultrasonic diagnostic apparatus is often used for puncture. In this case, an operator watches a monitor display of an ultrasound image of a live body and a puncture needle, and insertion of the puncture needle. In the puncture operation, a puncture adapter is often used, and a puncture guide marker is displayed on the monitor to serve as a direction guide to assist an operator during needle insertion. In one puncture method, a puncture adaptor is fixed at a predetermined position of an ultrasonic probe body. In this method, an operator must read an angle value by watching a scale on the adaptor, and set the angle value for displaying the angle of the puncture marker of the ultrasonic dia...
