Abstract

PURPOSE:To freely and easily operate a probe by removing a cable, by constituting the probe of a high frequency pulse generating circuit for driving a piezoelectric vibrator, a transmitting circuit part, a receiving circuit part, an imaging circuit of a received signal and an imaging monitor. CONSTITUTION:A piezoelectric vibrator 2 is closely brought into contact with the surface of the body to be probed and an ultrasonic pulse is generated from a high frequency pulse generating circuit 1. This ultrasonic pulse propagates through the body to be probed to reach the heterogeneous part in the body to be probed and partially reflected therefrom to become an echo which is, in turn, returned to the piezoelectric vibrator 2 to be received. This signal is processed by a transmitting circuit part 3 to be transmitted from a transmitting antenna 4. The radio wave signal transmitted from the transmitting circuit part 3 is received by a receiving circuit part 6 to be formed into an image on a monitor 7. As the monitor, or example, a cathode ray tube is used. by this constitution, it is unnecessary to connect a probe part, an imaging circuit and an image monitor by a cable and the operation is extremely facilitated.

Description

DETAILED DESCRIPTION OF THE INVENTION Field of Industrial Application The present invention relates to an ultrasonic probe device used for medical diagnosis and the like.

BACKGROUND OF THE INVENTION Conventionally, in this type of ultrasonic probe device, a probe part made of a piezoelectric vibrator is connected by a cable to a video circuit and a video monitor for processing and visualizing signals from the probe. was.

2 A-7' Problems to be Solved by the Invention In such a conventional configuration, the probe part, the video circuit, and the video monitor are connected by a cable, so when the probe part is moved, the cable is The cables were a major hindrance when moving the probe in complex ways.

The present invention is intended to solve these problems, and aims to provide an ultrasonic probe device in which the cable is removed and the probe portion can be easily operated.

Means for Solving the Problem In order to solve this problem, the present invention eliminates the cable that connects the probe section, the video circuit, and the video monitor, and instead transmits the signal from the probe wirelessly to the video circuit section. This method uses a method of transmitting information to

Function The method described above does not require a cable to connect the probe to the video circuit and the video monitor, so the probe can be moved freely, making it possible to provide an ultrasonic probe device that is easy to operate. can.

to 3-2 Example Hereinafter, one embodiment of the present invention will be described in detail using the drawings.

FIG. 1 is a block diagram of a transmitting section of an ultrasonic probe device according to an embodiment of the present invention. In FIG. 1, 1 is a high-frequency pulse generation circuit, 2 is a piezoelectric vibrator driven by the high-frequency pulse generation circuit 1, 3 is a transmitting circuit section for processing and transmitting the signal detected by the piezoelectric vibrator 2, and 4 is a A transmitting antenna that transmits signals. Then, the piezoelectric vibrator 2 is brought into close contact with the surface of the object to be probed, and the high-frequency pulse generation circuit 1 generates ultrasonic pulses. This ultrasonic pulse propagates inside the probed object, and when it reaches a foreign part inside the probed object, a part of it is reflected and becomes an echo, which returns to the piezoelectric vibrator 2 and is received. be done. This signal is processed by the transmitting circuit section 3 and transmitted from the transmitting antenna 4. FIG. 2 is a block diagram of the receiving section of the ultrasonic probe device according to the present invention. In FIG. 2, 5 is a receiving antenna, 6 is a receiving circuit, and 7 is a monitor. Then, a radio cathode ray tube transmitted from the transmitter is used.

Effects of the Invention As described above, according to the present invention, there is no need to connect the probe section made of a piezoelectric vibrator to a video circuit and a video monitor with a cable, and the probe section can be moved freely. The effect is that the operation becomes extremely easy.
