Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ultrasonic Doppler diagnostic probe.

[0002]

2. Description of the Related Art FIG. 5 shows an ultrasonic continuous wave (CW) in the human body.
To capture the reflected waves of moving particles that flow in the heart and blood vessels, and perform Doppler analysis to measure the blood flow velocity.
Schematic representation of the diagnostic system to display. In the figure, 51
Is an ultrasonic Doppler diagnostic probe that transmits an ultrasonic continuous wave and receives the reflected wave.

As this probe, as shown in FIG. 6 (a), a probe 51a which is pressed vertically against the body surface of the patient at the time of use, and a handle portion held by a hand at the time of use as shown in FIG. 6 (b) are provided. 51b forming an angle of about 45 degrees with the body surface,
Alternatively, as shown in FIG. 6 (c), there is one in which the handle portion forms an angle of about 30 degrees with the body surface during use, such as 51c.
These are stylized and typified so as to be able to adapt to the doctor's preference for holding (grip), and at least 2-3 probes with different angle shapes are provided in one diagnostic system.
It is a conventional practice to have types.

[0004]

However, it is troublesome for the manufacturer to prepare a plurality of types of expensive probes as in the prior art, and it is also uneconomical for the user to replace or replace the probe. There is an inconvenience that it is troublesome in terms of storage.

[0005]

In order to solve the above problems, the present invention provides a probe tip equipped with a transmitting / receiving unit for irradiating an ultrasonic continuous wave and receiving a reflected wave from a moving particle such as a human body. And an elongated probe handle part in which an electric wire for electrically connecting the transmitter / receiver part of the probe tip part to an external diagnostic device is wired and housed so as to penetrate therethrough. A Doppler diagnostic probe, wherein a male and female fitting portion is formed between the probe tip and the probe handle,
Fasten the fastening member so that it crosses and penetrates it.
The structural feature is that the mounting angle of the probe tip portion with respect to the probe handle portion can be freely set.

[0006]

[Operation] By fastening the fastening member to the male and female fitting portion formed between the probe tip portion and the probe handle portion so as to traverse and penetrate it, the probe tip with respect to the probe handle portion is loosened when the fastening member is loosened. The attachment angle of the portion can be set arbitrarily, and the fastening angle of the fastening member can be fixed at the attachment angle.

Embodiments of the present invention will be described below with reference to the drawings. 1 to 3 are views showing an embodiment of an ultrasonic Doppler diagnostic probe according to the present invention, and FIG. 4 is a perspective view showing a modification of a connecting portion between a probe handle and a probe tip.

First, referring to FIG. 1 to FIG. 3, the probe 1 of this embodiment is basically for electrical connection with a CW receiver and a CW transmitter, which is grasped by a user (doctor). It has an elongated probe handle 3 through which an electric wire passes, and a circular end surface in which a semicircular transmitting surface 5a and a receiving surface 5b are symmetrically arranged. Electric power is provided on the inner side of the transmitting / receiving surfaces 5a, 5b. An acoustic transducer (not shown) is arranged, and a probe tip 5 having a so-called backing member (not shown) is further arranged on the back side of the acoustic transducer, and the probe tip 5 is connected.

This connecting portion 7 is a slotted portion 9 formed so as to leave both side portions 8 parallel to the end portion of the probe handle portion 3.
Formed on the corresponding end portion of the probe tip 5,
A projecting portion 11 having a width dimension that fits snugly into the slit portion 9 is fitted, and a bolt (fastening member) is inserted through the sandwiched portion (8, 11, 8).
13 has been concluded.

By screwing in or loosening the bolts 13, the gap size (slitting size) between the both side portions 8 of the probe handle 3 becomes smaller or larger, so that the protruding portion 11 of the probe tip 5 located between them becomes smaller. By the frictional force, it is relatively fixed or rotatably held. Therefore, the user (doctor) can arbitrarily set the attachment angle of the probe tip 5 with respect to the probe handle 3 by adjusting (fastening) the bolt 13, and at the same time fix the angle easily and quickly so as to be released. Therefore, the usability of the probe 1 is significantly improved.
Further, with this configuration, one probe 1 is sufficient, so there is no need to prepare a plurality of types of probes, which is extremely rational and economical.

By the way, in addition to the configuration of the above embodiment, FIG.
As shown in FIG.
Saw-blade-shaped concave and convex surfaces 15 complementary to each other are formed on both engaging surfaces between both side parts 8 of the probe and the protruding portion 11 of the probe tip 5 to improve the adjustment feeling at the time of adjusting the angle and both. Can be configured to increase the frictional fastening force. In addition, the fastening bolts 13 may be caught on the clothing of the user,
In order to prevent the skin from being damaged, the bolt head portion is dimensionally and shapely configured to be embedded in both side portions 8 of the probe handle portion 3 when the bolt head portion is fastened.

Further, the so-called driver groove for fastening the bolt, which is engraved on the head of the bolt 13, has a coin, for example, 10 without using a special jig or tool (driver or the like).
It is finished in a size that can be easily turned with a round coin.

[0013]

As described above, according to the present invention, it is not necessary to prepare a plurality of types of expensive probes as in the conventional case, and one probe is sufficient.
This is extremely convenient for both the manufacturer and the user.
