Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to an ultrasonic diagnostic apparatus, and more particularly to a probe used in the ultrasonic diagnostic apparatus.

[0002]

[Prior art]

 The ultrasonic diagnostic apparatus radiates ultrasonic waves into the living body and diagnoses the state inside the body by the reflected waves. FIG. 2 shows a perspective view of a conventional ultrasonic diagnostic apparatus. This ultrasonic diagnostic apparatus is composed of a main body portion 10 and a probe portion 20. The main body unit 10 includes a display unit 11 for displaying a diagnostic image, an operation panel 12 for a doctor to perform various operations, and a machine unit 13 of the apparatus. The probe unit 20 is connected to the main body unit 10 by a cord 30, and a transducer group provided on one end surface of the probe unit 20 is applied to a region to be diagnosed, and ultrasonic waves are transmitted and received from the region to obtain an ultrasonic diagnostic image. . In recent years, as the technology has advanced, the performance and functions have become more and more advanced. With this, the contents to be operated increase and the number of operation keys on the operation panel increases. Is getting complicated.

[0003]

[Problems to be solved by the device]

 In most conventional ultrasonic diagnostic equipment, the probe unit is only provided with a vibrator group for transmitting and receiving ultrasonic waves to the subject, and the operation is performed from the operation panel of the main unit. Was there. In addition, some of the probes had a freeze key on the probe section to perform the freeze operation. However, operations other than the freeze operation were also performed on the operation panel.

When a doctor diagnoses a patient, a predetermined image may be displayed on the monitor in B mode, and the image on the monitor may be enlarged as necessary. In this case, in order to specify or move the position to enlarge, hold the probe with one hand and touch it at a predetermined position on the living body, and with the other hand, the general-purpose instruction changing device on the operation panel of the main unit, For example, I was moving a trackball. Therefore, the doctor has to perform separate operations with both hands at different positions, and the probe must be stationary during the diagnosis, which makes the operability very poor and makes it difficult for the doctor to make a diagnosis. I couldn't concentrate. Also, in order to operate separately with both hands, the ultrasonic diagnostic equipment main unit must be right next to the doctor during the diagnosis, and the place of installation is limited, so I think another diagnostic device next to the doctor. Could not be arranged.

The present invention has been made in view of the above problems, and an object of the present invention is to provide an ultrasonic diagnostic apparatus which has good operability and does not cause much trouble in the place of the apparatus main body during diagnosis. And

[0006]

[Means for Solving the Problems]

 The present invention adopts the following configuration in order to achieve such an object. That is, the ultrasonic diagnostic apparatus according to the present invention is an ultrasonic diagnostic apparatus including an ultrasonic diagnostic apparatus main body and a probe connected to the main body via a cord, and the ultrasonic diagnostic apparatus is provided with a diagnostic site. It is characterized in that the probe is provided with a general-purpose instruction changing means and an instruction confirming switch for performing an operation necessary for diagnosing by applying to the operator.

Hereinafter, how the ultrasonic diagnostic apparatus having this structure works will be described.

[0008]

[Action]

 In the ultrasonic diagnostic apparatus of the present invention, since the probe unit has a general-purpose instruction changing unit, the doctor simply applies the probe to the diagnosis region of the patient with one hand and moves his / her finger to easily enlarge / reduce the screen. Can be changed. Therefore, unlike the conventional case, the probe side and the operation panel are not operated with both hands, and the operability is significantly improved.

[0009]

【Example】

 Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a plan view showing the configuration of a probe of an ultrasonic diagnostic apparatus showing one embodiment of the present invention. Since the main body of the ultrasonic diagnostic apparatus of the present invention is the same as that of the conventional apparatus, the same reference numerals as those of the conventional apparatus are used and the description thereof is omitted. The probe portion 20 has a transducer portion 21 on one end surface, and a cord 30 for connecting to the main body 10 is attached to the opposite end surface. Further, on the front surface of the probe unit 20, there are provided a trackball 23 as a general-purpose instruction changing device and a key switch 24 which may be operated during diagnosis. In the key switch 24, the mode selection switch 24a, the enlargement / reduction switch 24b, the command image selection switch 24c, the freeze switch 24d and the same function as the key function freely selected by the doctor from the keys on the operation panel 12 can be registered and set. There are optional setting switches 24e and 24f. A signal generated by operating the trackball 23 or the key switch 24 is sent to the main body 10 by the code 30 and is sent to the control CPU via an I / O (not shown) in the main body. The main body 10 is provided with a conventional operation panel 12, and the doctor can perform the same operation by operating the operation panel 12 on the main body side if operability is not a problem.

Next, the operation of this ultrasonic diagnostic apparatus will be described. The doctor applies the transducer section 21 of the probe section 20 to the diagnostic region of the living body and tries to project a B-mode image first, for example. At this time, the B mode is selected by the screen selection key switch 24a. This operation produces a standard B-mode image. When it is desired to enlarge a part of the screen displayed next, the enlargement / reduction switch 24b is pressed. Then, an instruction frame for specifying the range appears on the screen. The pointing frame is moved by the trackball 23 to specify a desired position. By pressing the key switch 24b again, an enlarged image of the designated range can be obtained. When it is desired to move the M mode cursor display key during the B / M mode display, first select the B / M mode with the screen selection key switch 24a to display the B mode image and the M mode image. I'll do it. Then, the operation changeover switch 24c for selecting which of the B-mode image and the M-mode image the command is to be sent to is pressed so that the instruction works on the M-mode screen. In this state, when it is desired to enlarge / reduce a part of the M-mode image, the enlargement / reduction switch 24b is pressed and the range is designated by the trackball 23 to perform the enlargement / reduction display. When the freeze operation is performed after the desired screen is obtained, the freeze image is obtained by pressing the freeze key 24d.

Further, if the doctor sets a command for calculating the number of nights in the arbitrary setting switch 24e, pressing this key causes the number of nights in night to be calculated immediately. In addition, by setting arbitrary setting keys according to the contents that the doctor frequently diagnoses from various measurements such as distance measurement, area perimeter measurement, volume measurement, valve speed measurement, etc. It is possible to easily perform measurement by operating the trackball 23 and the key switch 24 on the probe side without performing the operation of 12.

In this embodiment, the so-called linear type probe is used, but the probe is not limited to this. Further, although the trackball is used as the general-purpose instruction changing device, another general-purpose instruction changing device may be used. Although the number of the key switches 24 is six in this embodiment, the number and shape of the key switches 24 are not limited to this.

[0013]

[Effect of device]

 According to the ultrasonic diagnostic apparatus of the present invention, the M mode cursor can be moved and the image can be enlarged or reduced with one hand while the probe is applied to the living body for diagnosis. The operability is extremely good.
