Description

{INJECTION DEVICE WITH ULTRASONIC PROBE}

The present invention relates to an ultrasonic probe scanning apparatus using an RCM, and more particularly, to an insertion apparatus for an ultrasonic probe which can easily adjust an insertion depth and an insertion angle of a scanning unit inserted into a lesion site, And the target point to which the ultrasonic probe is to be held remains the same.

There are many patients who are suffering from intense muscle movements without preparation exercise and suffer from muscle shock or muscle damage.

In order to diagnose muscle damage or myoma of such patients, biopsy of intracorporeal tissue of a patient is performed by using musculoskeletal ultrasound in the orthopedic and pain medicine departments. In the past, by using an ultrasonic probe, The method of diagnosis is as follows.

A right-handed examiner moves the ultrasonic probe while the ultrasonic probe is gripped with a right hand, examines a lesion site, and after the ultrasonic probe placed in the right hand is transferred to the left hand, the injection unit is gripped with a right hand, The injection site is injected into the site or puncture is performed.

However, in the conventional method of diagnosing a lesion site, the inspection position of the ultrasonic probe is frequently changed as the ultrasonic probe held by the right hand is replaced with the left hand in order to insert the injection unit into the lesion site, There has been a problem in that the image generated based on the echo of the ultrasonic wave is changed so that the examinee must reaffirm the lesion site.

As a conventional technique for solving such a problem, an ultrasonic probe integrated type scanning device is disclosed in Japanese Patent Registration No. 10-1409836 (registered on Apr. 2014. 06. 13.), and Fig. 1 is a schematic diagram of an ultrasonic probe- Sectional view of the device.

The ultrasonic probe integrated type scanning apparatus includes a main body 10, a supporting unit 11, a scanning unit 12, an angle adjusting unit 13, a front and rear power providing unit 14, an operation unit 15, an ultrasonic probe 16, An angle detection unit 17 and a control unit 18. [

The main body 10 of the prior art is formed in a gun shape and has a receiving space 10a formed therein to provide an installation area of another configuration and to support the supporting unit 11, So that it can be moved in the forward and backward directions while being supported by one side of the support portion 11. [ A mode switch 10b and a drive switch 10c are provided on one side of the main body 10. The mode switch 10b can select one of an angle adjusting mode, a scan unit moving mode, and a piston driving mode And the drive switch 10c is for driving the corresponding mode when the mode is selected by the mode switch 10b and the drive switch 10c is turned on when the angle adjustment mode is selected by the mode switch 10b On, the turning force providing means 13a of the angle adjusting means 13 is driven. When the driving switch 10c is turned on with the scanning unit moving mode selected by the mode switch 10b, And the cylinder rod 15a of the cylinder block 15 is moved back and forth.

However, since the conventional technique has a weak supporting force, there is a problem that the insertion angle of the scanning unit can be instantaneously changed when inserting the scanning unit. Since the scanning unit can be adjusted only at the upper and lower angles, There is a problem that insertion of the scanning unit is difficult.

As a conventional technique for solving such a problem, an ultrasonic probe two-sided supporting type scanning device is disclosed in Japanese Patent No. 10-1508919 (registered on May 31, 2013), and Fig. 2 is a cross- 2 is a perspective view of a two-hand holding type scanning device.

The ultrasonic probe two-handed supporting type scanning device includes an ultrasonic probe 20, a probe support 21, a shaft 22, an adjusting body 23, a scanning angle adjusting means 24, a vertical height adjusting means 25, Adjustment means (26) and scanning unit fixing means (27).

The prior art allows the injection needle of the scanning unit 28 to be accurately inserted into the lesion site detected by the ultrasonic probe 20 while the ultrasonic probe 20 and the scanning unit 28 are coupled to each other, 20 and the scanning unit 28 are supported by both hands, it is possible to prevent the insertion angle of the injection needle from changing when the injection needle of the injection unit 28 is inserted, 28 to be inserted easily.

However, in the conventional technique, the needle insertion angle of the scanning unit 28 is adjusted by the adjustment of the scanning angle adjusting means 24. In order to adjust the needle insertion angle of the scanning unit 28, It is necessary to fix the scanning angle adjusting means 24 through the operation of the angle adjusting screw 26a in a state in which the scanning needle insertion angle of the scanning unit 28 is adjusted by the adjustment of the adjusting screw 24 .

In order to adjust the needle insertion depth of the scanning unit 28, the depth of the injection needle insertion depth of the injection unit 28 is adjusted by adjusting the vertical height adjustment means 25. In order to adjust the injection needle insertion depth of the injection unit 28, There is a problem that both hands must be used since the vertical height adjusting knob 25a must be rotated in a state in which the probe 20 or the probe support table 21 is grasped.

5, the ultrasonic probe 120 detects a lesion site through an image generated based on an echo of an ultrasonic wave. The ultrasonic probe 120 includes a knob 121, a body connected to the knob 121, And a divergent part 123 connected to the body 122. The body 122 is rotatably installed in the housing 110. The body 122 is rotatably installed in the housing 110. [ At this time, the divergent part 123 of the ultrasonic probe 120 may be rotatable on the body 122.

According to the present invention, the ultrasound probe 120 is connected to a monitor device (not shown) and transmits an image signal to the monitor device so that the ultrasound probe 120 can be visually recognized and internal lesions can be detected .

The operation using the ultrasonic probe 120 and the scan unit 200 may be classified into real-time or approach angle. The indirect operation and the real operation are classified into real- -time technique. There are in-plane apprehension and out-of-plane approach as approaches classified according to approach angle.
