Description

Intubation device for ultrasonic probe

The present invention relates to a technique for inserting a needle into a living body using an ultrasonic probe.

With the advancement of science and technology, interest in medical devices that can utilize oriental medicine treatment technology is also increasing. Among them, in acupuncture procedures, most side effects, such as bleeding, hematoma, inflammation, pneumothorax, and nerve damage, are based on the damage to the anatomical organs present at the treatment site. There is a need for devices.

In the related art, a method of observing an area where acupuncture is invaded using an ultrasonic probe and performing acupuncture using observed image data has been used. However, the above method has a limitation in that there is a difference in the ability of each medical practitioner and cannot guarantee the accuracy due to the difference in the ability to calculate the depth and direction in which the needle is invaded by a person reading the observed image data. .

Therefore, an ultrasonic guide for acupuncture needles has been developed to help the acupuncture operation safely at a dangerous site by accurately sensing the insertion depth and direction of the needle by finding the magnetized needle through a magnetic sensor mounted in the ultrasonic probe.

However, a structure is needed to fix and mount the needle to use the ultrasonic probe in one hand and to locate and insert the correct position in the other hand. There was a method in which a syringe needle was inserted into the skin through an ultrasound guide during biopsy in both conventional methods, but most of them are fixed to the side of the ultrasonic probe.

In addition, since acupuncture is removed and the acupuncture is performed to insert the needle deeply after using the intubation to locate the acupuncture during acupuncture treatment, there is a limitation in utilizing the guide system used in both methods for acupuncture. That is, there is a need for an intubation structure specialized for acupuncture that can easily remove the intubation and easily change the position of the acupuncture.

The present invention provides an intubation device for an ultrasound probe that allows an operator to easily insert a needle from a circumference around an ultrasound probe into a target site based on an image of tissue in vivo.

In addition, the present invention is specialized in acupuncture, and provides a tube-mounting device for an ultrasonic probe that can be detached.

The present invention is an apparatus for mounting a needle tube for an ultrasonic probe, wherein a holder for fixing the needle tube so that one needle faces the biological direction is formed, and the other end has a ring-shaped needle tube fixing part; And it is mounted on the ultrasonic probe in a form surrounding the ultrasonic transmission/reception portion of the ultrasonic probe, and includes a cradle formed with a guide groove capable of moving around the ultrasonic transmission/reception portion in a state where the hook of the intubation fixing part is hung on the upper surface.

According to the present invention, the operator can easily insert the needle into the target site by allowing the position of the needle tube to move freely around the ultrasound probe based on the image of the tissue in vivo.

In addition, according to the present invention, the acupuncture tube is detachable so that the operator is provided with convenience specialized in acupuncture.

Embodiments of the present invention are provided to more fully describe the present invention to those skilled in the art. Therefore, the shape and size of elements in the drawings may be exaggerated for a more clear description.

In the specification, acupuncture refers to an oriental medicine treatment method using acupuncture to relieve adhesion of soft tissues such as muscles, fascia, and ligaments of a living body, or to perform partial incisions and to relieve chronic pain caused by damage to soft tissues. .

1 is a perspective view showing an example in which the intubation device according to an embodiment of the present invention is mounted on an ultrasonic probe, and FIG. 2 is an intubation device for explaining an aspect of an upper sidewall of a guide groove according to the present invention 3 is a perspective view of an intubation mounting device for explaining another aspect of an upper side wall of a guide groove according to the present invention.

1 to 3, the intubation device for an ultrasonic probe according to an embodiment of the present invention includes a holder 100 and a needle tube fixing part 200.

The cradle 100 is mounted on the ultrasonic probe 10 in a form surrounding the ultrasonic transmitting/receiving portion 11 of the ultrasonic probe 10.

The ultrasonic probe 10 may transmit a pulse wave object having a high frequency exceeding a human audible frequency range. In addition, the ultrasound probe 10 may receive the reflected wave from the object, amplify and convert the reflected wave using the difference in acoustic resistance in the object, and generate ultrasound image data associated with the object. Accordingly, the ultrasound probe 10 may provide the user with location information of bones, organs, nerves, and blood vessels inside the object. Accordingly, the user can perform acupuncture on the object by avoiding the dangerous area, thereby minimizing side effects caused by acupuncture.

Here, the ultrasound probe 10 may be configured as a 2D ultrasound probe capable of acquiring a 2D image or a 3D ultrasound probe capable of acquiring a 3D image.

For example, the 3D ultrasonic probe may be configured to move a one-dimensional array type ultrasonic transducer in which ultrasonic elements are arranged on a single axis in a direction perpendicular to the arrangement axis of the ultrasonic elements. Here, since the one-dimensional array type ultrasonic transducer acquires a two-dimensional cross-section image, a three-dimensional image can be obtained by moving the one-dimensional array type ultrasonic transducer in a direction perpendicular to the array axis of the ultrasonic elements. As another example, the 3D ultrasound probe may be configured to acquire a 3D image by a two-dimensional array type ultrasonic transducer arranged on a plurality of axes in which ultrasonic elements intersect each other.

The cradle 100 may have an outer portion of a circular, elliptical, or polygonal shape, and a mounting hole 101 is formed in the central portion. The mounting hole 101 is formed to fit and support the circumferential portion of the ultrasonic probe 10 while passing the ultrasonic transmission/reception portion 11 of the ultrasonic probe 10.

The cradle 100 may be attached to the circumferential portion of the ultrasonic probe 10 by an adhesive or the like, but may be detachably mounted on the ultrasonic probe 10.

In this case, according to an aspect, the clasp 120 and the hinge 130 for tightening the ultrasonic probe 10 and the cradle 100 are formed so that the ultrasonic probe 10 is mounted on the cradle 100. Thus, the ultrasonic probe 10 can be more stably maintained in a state fitted in the mounting hole 101. At this time, the clasp 120 and the hinge 130 are formed on both sides of the diagonal of the cradle 100. Thus, the movement of the needle tube fixing unit 200 is not prevented. According to another aspect, the holder 100 may be attached to the surface 140 in contact with the ultrasonic probe 10, a sponge or a rubber material to be fixed to the ultrasonic probe 10. Meanwhile, of course, various fixing means may be used in addition to the above-described fixing means.

In addition, the height of the cradle 100 may need to be adjusted depending on the type of saliva used or the treatment site. To this end, according to an aspect, the cradle 100 may be moved up and down based on the bottom surface of the transmitting/receiving portion of the ultrasonic probe 10 by a knob that adjusts the clasp 120. Accordingly, according to the type of the needle and the treatment site, the height from the bottom surface of the transmission/reception site of the ultrasonic probe 10 of the cradle 100 can be adjusted.

On the other hand, the present invention is a part of the ultrasonic guide system for acupuncture needles that assists the dangerous procedure by acquiring depth and direction information of a magnetized needle with ultrasound and a magnetic sensor when acupuncture points in a human body part are secured by fixing the insertion direction. It may be an invention for a needle tube mounting device for an ultrasonic probe, which is a structure for allowing needles to sleep. Accordingly, according to an embodiment, the cradle 100 and the needle tube fixing part 200 may be made of a non-magnetic material that does not interfere with the probe magnetic sensor (not shown) for positioning the magnetized needle. However, this is only an example, and the tube-mounting device for ultrasonic probes of the present invention is not limited to an ultrasonic guide system for needles.

On the other hand, in the state in which the ring 220 of the intubation fixing part 200 hangs on the surface (hereinafter referred to as the'upper surface') opposite to the bottom surface direction of the transmitting/receiving portion of the ultrasonic probe 10 in the cradle 100 A guide groove 110 is formed to allow the government 200 to move around the ultrasonic transmission/reception site 11. Accordingly, the operator makes the hook 220 of the needle tube fixing part 200 to which the needle tube 20 is fixed by the holder 210 is caught in the guide groove 110, and then the needle tube fixing part is guided along the guide groove 110. By allowing the 200 to be moved, the acupuncture tube 20 can be positioned at a target site for acupuncture in vivo.

Here, according to one aspect, as shown in FIG. 2, the outer sidewall upper surface 130 of the guide groove 100 is formed in a flat (Flat) shape, the ring 220 of the needle tube fixing part 200 is guided It can be made to slide along the groove (110). In this case, there is an advantage that it is easy to manufacture as well as easy to change the position.

According to another aspect, as shown in FIG. 3, the upper and lower side walls of the guide groove 110 may be formed with a sawtooth-shaped irregularity 131 in units of a predetermined length. However, the shape of the unevenness 131 may be a polygon or a circle including a square, a triangle, in addition to a sawtooth shape. Thus, the ring 220 of the needle tube fixing portion 200 is moved in units of the unevenness 131, so that the adjusted final position can be performed without the needle shaking.

Meanwhile, as described above, the holder 210 for fixing the needle tube 20 so that the needle faces the living body direction is formed at one end of the needle tube fixing part 200, and the ring 220 is formed at the other end. Here, the acupuncture tube 20 may provide a user with a path through which the needle penetrates to invade the object for acupuncture.

Referring to FIG. 4, a plurality of intubation fixing parts 200-1, 200-2, and 200-3 may be mounted on the cradle 100. In addition, the holder shapes of the needle tube fixing parts 200-1, 200-2, and 200-3 may be different from each other.

According to one aspect, the intubation fixing part 200-1 is formed such that the holder 210a extends from one end of the ring to enclose the surface of the intubation. For example, as illustrated in FIG. 4, it may be a holder 210 having a circular shape. In this case, the fixation of the intubation can be strengthened. According to another aspect, the needle tube fixing part 200-2 may allow the holder 210b to extend vertically from both ends of one end of the ring. In this case, fixation of the needle tube may be easier compared to the circular holder. According to another aspect, the intubation fixing part 200-3 may be formed so that the holder 210c extends vertically from both ends of one end of the ring, so that the fillet 211 is processed at the end of the extension part to prevent opening. .

On the other hand, the holder 210 of the needle tube fixing part 200 is formed so that the distance between points contacting the needle tube is smaller than the distance between points of the corresponding needle tube. That is, the inner diameter or the inner width of the holder 210 is slightly smaller than the outer diameter of the needle tube 20 so that the needle tube 20 can be detachably attached to the holder 210. Thus, in acupuncture, acupuncture tubes that are necessary only at the start of acupuncture can be removed when the needle is inserted.

Meanwhile, the angle of inserting the needle into the body needs to be adjusted according to the position of the target site in the body. That is, if the depth of the target site is different from the surface of the living body, it is necessary to vary the angle of inserting the needle into the living body accordingly.

In FIG. 5, an angle adjustment example of the intubation fixing part 200-1 having the circular shape holder 210a shown in FIG. 4 is illustrated, in which case the intubation fixing part 200-1 is manually bent in a form of bending The angle of (20) can be adjusted. To this end, the connection portion between the holder 210a and the hook 220 of the needle tube fixing part 200-1 should be made of an elastic material. For example, it is made of an elastic material for a predetermined length at the connection end of the holder 210a and the ring 220, or a connection part (not shown) made of an elastic material between the holder 210a and the ring 220 may be implemented in a form additionally configured. It might be.
