Further, the grip is disposed upper than the centroid and, therefore, the operability is excellent.

Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention (Field of Industrial Application) The present invention relates to a probe used in an ultrasonic diagnostic apparatus.

(Prior Art) A conventional probe 1 for an ultrasonic diagnostic apparatus will be explained with reference to FIG. Reference numeral 2 denotes a plurality of transducers or ultrasonic transducers arranged in an array, and each transducer 2 is connected to a signal line 3a for transmitting a transmission/reception signal, and this signal line 3a is connected via a connector 3b. It is pulled out by a cable 3 and connected to a signal processing section of the main body of the device (not shown). The ultrasonic transducer 2 and signal line 3a are molded with a filling member 5a made of insulating resin, and a grip portion 4 is formed by constricting the vicinity of the connector 3b so that it can be easily gripped by the operator's fingers. . Further, the bottom surface of the ultrasonic transducer 2 becomes the living body contact surface 2a.

(Problem to be Solved by the Invention) During ultrasonic diagnosis, the operator supports the grip portion 4 of the probe 1 with his or her fingers and shifts the position of the ultrasound transducer 2 while applying the living body contacting surface 2a to the living body. It is designed to be operated.

The grip portion 4 is formed in a fixed manner, and in the example shown in FIG. 8, is formed in a direction perpendicular to the living body contact surface 2a. There was a problem in that the part 4 became difficult to hold and the operability deteriorated.

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a probe for an ultrasonic diagnostic apparatus with excellent operability.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, the present invention provides a probe in which an ultrasonic transducer and a signal line are molded with a filling member, which is removable from the filling member. The probe is characterized by having a grip attached to the probe, and the grip is detachably attached to the filling member on the opposite side of the ultrasound transducer across the center of gravity of the probe.

(Function) The function of the probe with the above configuration will be explained. Good operability can be achieved by attaching a grip having an appropriate shape to the filling member as required.

Furthermore, by attaching the grip to the side opposite to the ultrasonic transducer with respect to the center of gravity of the probe, the center of gravity is closer to the ultrasonic transducer than the grip, resulting in better operability.

(Embodiment) A probe 10 according to an embodiment of the present invention will be specifically described below with reference to the drawings. In the following description, the same components as those in FIG. 8 are denoted by the same reference numerals, and detailed description thereof will be omitted.

1 to 3 are views relating to the first embodiment probe 10, in which FIG. 1 is a side view, FIG. 2 is a lateral sectional view, and FIG. 3 is a sectional view taken along the line AA shown in FIG. 2. It is.

This probe 10 includes an array of ultrasonic transducers 2, a signal line 3a connected to this, and a connector 3b that connects the signal line 3a.
The probe 1 is similar to the probe 1 shown in FIG. 8 in that it includes a cable 3 that leads to an external device via a cable 3, and a filling member 5a that covers the vibrator 2 and the signal line 3a.

This probe 10 has a different configuration from the conventional probe 1.
has a grip 14 that is detachably attached to the grip portion 4 above the center of gravity G1o of the probe 10.

This grip 14 has a concave portion 14a on its circumferential surface that matches the shape of the finger for easy gripping, and has a two-part structure consisting of members 14b and 14c as shown in FIG.
B by connecting pins 14d provided on each part of 4b and 14c.
It is designed to be removable in both directions.

According to the probe 10 configured in this way, the operator can easily select and attach a grip that is easy to grip depending on the part of the living body to be imaged or the posture of the living body, and furthermore, since the grip is placed above the center of gravity, An ultrasonic diagnostic probe with excellent operability can be provided.

4 to 7 are views relating to the second embodiment probe 20, in which FIG. 4 is a side view, FIG. 5 is a sectional view of main parts, and FIGS. 6 and 7 are shown in FIG. 4. FIG. 7 is a side view showing another example of the grip 24.

This probe 20 has a biological contact surface 22a of the ultrasound transducer 22 in a direction substantially perpendicular to the direction in which the cable 23 is led out. Further, this probe 20 includes an array-shaped ultrasonic transducer 22 configured similarly to the probe 10 of the first embodiment, a signal line (not shown) connected to this, and a signal line that is externally connected via a connector 23b. A cable 23 leading to the device, a filling member 2 covering the vibrator 22 and the signal line
5a, and a grip 24 that is removably attached to the surface of the filling member 25a above the center of gravity G20 of the probe 20 and opposite to the surface on which the ultrasonic transducer 22 is arranged. .

This grip 24 has a biological contact surface 2 as shown in FIG.
A rail 24a is provided at the lower part of the grip 24 on a rail receiver 25b which has a shape inclined with respect to the grip 2a and is disposed on the opposite side of the living body contacting surface 22a of the filling member 25a as shown in FIG. By inserting it in the horizontal direction C, it can be easily attached to the filling member 25a.
