Description

The present invention relates to an ultrasonic diagnostic apparatus, a puncture ultrasonic probe, and a puncture adapter that are used when a puncture needle is inserted using a puncture adapter attached to an ultrasonic probe.

When inserting a puncture needle into a patient, a puncture is often performed using an ultrasonic diagnostic apparatus while observing the patient's biological tomographic image and the inserted needle image. In this puncture technique, a puncture adapter is generally used as an ultrasonic probe, and a puncture needle is inserted using a puncture marker image displayed on a monitor as a guide. As one of the methods, there is a method in which the puncture adapter is fixed at a predetermined position of the body of the ultrasonic probe. In this method, a puncture needle guide attached to a slider that slides inside the puncture adapter 51 is fixed with a screw or the like, and an angle indicated on the scale of this adapter is read and set as a puncture marker display angle of the ultrasonic diagnostic apparatus. To do. With this setting, a puncture marker image is displayed on the ultrasonic tomographic image displayed on the monitor. In the structure of reading and setting in this way, it is necessary to reset the puncture marker display angle of the ultrasonic diagnostic apparatus each time the puncture angle is changed, which is very complicated.

On the other hand, the angle of the puncture needle guide described above may be detected by a sensor provided in the puncture adapter, and the detection result may be transmitted to the processing unit of the ultrasonic diagnostic apparatus (see, for example, Patent Document 1).
). The sensor for detecting the angle of the puncture needle guide is a portion near the portion where the puncture needle guide of the puncture adapter body moves or a portion where the extension terminal connected to the puncture needle guide moves (for example,
6 and 7 of Patent Document 1) and detects the angle of the puncture needle guide directly or indirectly. The detected electrical signal is transmitted to the ultrasonic diagnostic apparatus, and is automatically changed and displayed on the ultrasonic tomographic image displayed on the monitor in accordance with the angle detected by the puncture marker image.

When the holder 21 is fitted and mounted, as shown in FIG. 3C, all elements of the optical sensor section 13 in which the light emitting elements 13a and the light receiving elements 13b provided in the probe body 11 are alternately arranged in an arc shape slide. Light that is exposed from the opening 22 and emitted from the light emitting element 13a does not enter any of the light receiving elements 13b, and no signal is output from these light receiving elements 13b. The position of the needle guide 24 is the maximum insertion angle of the puncture needle (when the vertical insertion angle is 0 degree).

Next, the needle guide 24 is moved together with the slider 23 along the slide opening 22 to the probe body 1.

The angle is measured and the result is input to the CPU unit 36. The CPU unit 36 instructs the image recording device 38 to output puncture guide image data corresponding to the detected puncture needle insertion angle to the display unit 37.

In addition, the angle detection sensor is disposed on the body of the ultrasonic probe, and the puncture adapter has no electrical mechanism. Therefore, disinfection and sterilization can be performed without fear of circuit breakage or electric leakage due to heat or moisture. In addition, since the puncture adapter itself can be configured at a lower cost than the puncture adapter provided with the sensor, the puncture adapter can be used as a disposable. Furthermore, since the lead wire for the sensor signal is also wired inside the probe body, it is not necessary to provide connection means such as a connector outside the probe. Furthermore, the transmission cable to the main body is connected by a probe cable integrated with the transducer cable, and an ultrasonic probe equipped with a puncture guide with excellent operability can be provided.

In this case, a plurality of coils as sensors are arranged in an arc shape on the sensor unit, and current generated by passing a magnetized magnetic body provided on the slider can be detected and used as angle information.

Further, a current due to a change in capacitance may be detected. Also at this time, the angle information can be detected by arranging a plurality of coils as a sensor in an arc shape on the sensor portion and passing a conductor provided on the slider.

Furthermore, the position of the slider may be detected by transmitting and receiving ultrasonic waves instead of light. This can be realized, for example, by configuring the light receiving element and the light emitting element in the first embodiment with an ultrasonic transducer.
