Accordingly, by matching the radiation direction of ultrasonic waves emitted from the ultrasonic probe with the discharge direction of the injection solution discharged through the micro channel, injecting the injection solution directly to the position in the image obtained from the ultrasonic probe.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an ultrasound imaging apparatus having a pneumatic scanning function,

The present invention relates to an ultrasound imaging apparatus having a pneumatic scanning function, and more particularly, to an ultrasound imaging apparatus having a pneumatic scanning function capable of precisely injecting an injection liquid at a position where an ultrasound image appears under the guidance of an ultrasound image.

The ultrasound imaging apparatus irradiates an ultrasound signal from a body surface of a target object toward a desired site in the body and obtains an image related to a tomography or blood flow of the soft tissue using the information of the reflected ultrasound signal (ultrasound echo signal) It is widely used in the medical field.

Such an ultrasound imaging apparatus is small, inexpensive, and displayable in real time as compared with other image diagnostic apparatuses such as an X-ray diagnostic apparatus, a CT scanner (Magnetic Resonance Image), a MRI (Magnetic Resonance Image) X-ray, etc., and is widely used for diagnosis of heart, abdomen, urinary and obstetrics.

2. Description of the Related Art Generally, an ultrasound imaging apparatus includes an ultrasound probe for emitting an ultrasound signal to a target object to receive an ultrasound image of the target object and receiving an ultrasound echo signal reflected from the target object.

Such an ultrasound imaging apparatus is sometimes used in combination with a procedure of injecting an injection liquid into a specific site while checking an ultrasound image. For example, the subcutaneous tissue is injected into an accurate position while observing an ultrasound image .

However, there is a problem that it is difficult to precisely grasp the position and direction of the needle during the process of approaching the desired position by inserting the medical needle. This shows that the ultrasound image shows only a section having a very narrow width at a specific depth on the screen, which makes it difficult for the practitioner to know the position of the medical needle to be injected at present.

In addition, since the medical needle itself is not easy to distinguish within the ultrasound image, it is practically difficult to grasp the precise position of the medical needle even if it is performed while viewing the ultrasound image.

Therefore, in the case of ultrasound, a lot of experience is accumulated, and skilled doctors have a problem that it is easy to perform a procedure using a freehand technique without a separate guide.

In order to solve the above problems, Korean Patent Laid-Open Publication No. 10-2014-0040827 discloses a needle guide for guiding insertion of a medical needle at various angles on a side surface of an ultrasonic probe. However, the technique disclosed in Korean Patent Laid-Open Publication heretofore has a problem that only the medical needle is guided at a certain angle, and the insertion angle needs to be dependent on the experience of the operator in order to approach the actual lesion.

Accordingly, it is an object of the present invention to provide an ultrasound imaging apparatus having a pneumatic scanning function capable of precisely injecting an injection liquid at a position where an ultrasound image appears under the guidance of an ultrasound image.

According to another aspect of the present invention, there is provided an ultrasonic imaging apparatus having a pneumatic scanning function, comprising: an ultrasonic probe for acquiring an ultrasonic image; A microchannel having one side communicated with the front end of the ultrasonic probe and the other side communicating with an outer diameter of the ultrasonic probe; And a pneumatic syringe connected to the other side of the microchannel and injecting an injection liquid into a front end of the ultrasonic probe through the microchannel.

Here, the microchannel may be formed in the ultrasonic probe so as to inject the injection liquid in a direction coinciding with the radiation direction of the ultrasonic waves radiated from the ultrasonic probe.

The pneumatic syringe is provided with a second fastening part which can be engaged with the first fastening part, and the first fastening part and the second fastening part are provided on the outside diameter of the ultrasonic probe, The pneumatic syringe may be detachable from the ultrasonic probe through detachment between the second fastening portion.

According to the present invention, by injecting the injection liquid into the position of the image obtained from the ultrasonic probe by matching the radiation direction of the ultrasonic wave emitted from the ultrasonic probe with the injection direction of the injection liquid discharged through the microchannel, .

1 is a perspective view of an ultrasound imaging apparatus according to the present invention,
2 is a side view of the ultrasound imaging apparatus according to the present invention.

Hereinafter, embodiments according to the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a perspective view of an ultrasound imaging apparatus according to the present invention, and FIG. 2 is a side view of an ultrasound imaging apparatus according to the present invention. 1 and 2, an ultrasound imaging apparatus having a pneumatic scanning function according to the present invention includes an ultrasound probe 100, a microchannel 110, and a pneumatic syringe 300.

The ultrasonic probe 100 acquires an ultrasound image. More specifically, the ultrasound probe 100 transmits an ultrasound signal to a target object to obtain an ultrasound image of the target object, receives the ultrasound echo signal reflected from the target object, and acquires an ultrasound image.

The micro channel 110 is formed inside the ultrasonic probe 100. One side of the microchannel 110 communicates with the front end of the ultrasonic probe 100 as shown in FIG. 2, and the other side communicates with a side-side outer diameter of the ultrasonic probe 100.

The pneumatic syringe 300 is connected to the other side of the microchannel 110 and the side of the ultrasonic probe 100. The pneumatic syringe 300 injects the injection liquid into the front end of the ultrasonic probe 100 through the microchannel 110.

At this time, the micro channel 110 is formed inside the ultrasonic probe 100 so as to inject the injection liquid in a direction coinciding with the radiation direction of the ultrasonic waves radiated from the ultrasonic probe 100.

According to the above-described configuration, a practitioner such as a doctor acquires an ultrasound image in a state in which the ultrasound probe 100 is in close contact with the skin surface of the patient, and observes the ultrasound image displayed on a screen I will find you.

When the ultrasonic image is displayed on the screen and the position of the tissue to be injected is indicated on the ultrasound image, the injected fluid is injected into the patient's body through the micro channel 110 by operating the pneumatic injector 300, Injection of the injection liquid becomes possible.

At this time, since the injecting depth of the injecting liquid can be adjusted by adjusting the pneumatic pressure of the pneumatic injector 300, the practitioner can inject the injecting liquid into the correct position while looking at the screen.

As shown in FIG. 2, a first coupling part 120 may be provided on the side surface of the ultrasonic probe 100 to communicate with the other side of the microchannel 110. The pneumatic syringe 300 may be provided with a second fastening part 320 which can be engaged with the first fastening part 120. Here, the second fastening part 320 may be provided at an end of the connection tube 310 extending from the second fastening part 320, as shown in FIG.

The pneumatic syringe 300 can be detached from the ultrasonic probe 100 through the attachment and detachment between the first coupling part 120 and the second coupling part 320 so that the ultrasonic probe 100 and the pneumatic syringe 300 can be separated from each other, Can be utilized more efficiently.

It is to be understood that both the foregoing general description and the following detailed description of the present invention are exemplary and explanatory and are intended to be exemplary and explanatory only and are not to be construed as limiting the scope of the inventive concept. And it is obvious that it is included in the technical idea of the present invention.
