Before describing the present invention, the ultrasound system medical treatment jaw joint cutting tip transmits ultrasound vibration energy in a state of being connected to medical equipment using an ultrasound system.

Here, the medical equipment using the ultrasonic wave method is a device including a main body (not shown) for generating vibration energy in an ultrasonic manner and a handpiece 10 connected to the main body through a cable so as to be mountable .

Thus, ultrasonic vibration of about 24 to 32 KHz is transmitted to the jaw joint cutting tip for ultrasonic medical treatment according to the present invention.

In this case, the vibration in the range of 24 to 32 KHz applied to the jaw joint cutting tip is a frequency range in which the cutting force is exerted only on the cervical tissue such as the jaw joint, and the range of vibration that can be absorbed by soft tissue such as skin, blood vessels, Is not added.

1 to 5, the jaw joint cutting tip for ultrasonic medical treatment according to the present invention includes a joint part 100, a straight bar 200, a first bending bar 300, (400), and a cutting portion (500).

First, the coupling portion 100 may be coupled to and separated from the ultrasonic medical handpiece 10.

Here, the coupling portion 100 may have a cylindrical body having a predetermined length, and a fastening structure (not shown) is provided at a rear end of the coupling portion 100 for coupling to the handpiece 10.

The coupling unit 100 couples the fastening structure of the rear end to the front end fastening structure of the handpiece 10, and then the ultrasonic vibration is transmitted from the handpiece 10.

The ultrasonic vibrations transmitted to the coupling unit 100 are transmitted to the cutting unit 500 through the linear bar 200, the first and the second bending bars 300 and 400 to be described later.

The straight bar 200 refers to a portion that is firstly extended so that a cutting portion 500 to be described later can be positioned at a predetermined length from the coupling portion 100.

Here, the straight bar 100 may have a circular beam shape extending linearly from the front end of the coupling part 100.

The straight bar 200 may be connected to the longitudinal center axis line of the coupling part 100 by the same central axis line and the straight line bar 200 may have a smaller diameter than the coupling part 100 .

That is, the rectilinear bar 200 maintains a distance between the portion of the operator holding the handpiece 100 and a cutting portion 500 to be described later.

The straight bar 200 may be made of a metal such as stainless steel which is resistant to corrosion and has an appropriate strength and an elastic force.

The first banding bar 300 may have a circular beam shape bent and extended at an angle larger than a right angle from the front end of the straight bar 200 toward the left or right direction.

Here, the first bending bar 300 is connected to have the same center axis line as the longitudinal center axis line of the straight bar 200.

1, the first bending bar 300 is bent in the right direction. However, the bending direction of the first bending bar 300 can be selectively used according to the direction of the left and right jaw joints.

The longitudinal bending axis line of the first bending bar 300 is diagonal to the longitudinal center axis line of the straight bar 200.

At this time, it is preferable that the longitudinal center axis line of the first banding bar 300 has an inclination angle within a range of 130 to 150 degrees (degrees) with the longitudinal center axis line of the straight line bar 200.

Since the first bending bar 300 has an inclination angle within the range of 130 to 150 degrees, interference with the adjacent jaw joints is reduced when the cutter 500 is inserted into the operation or treatment area .

That is, the first banding bar 300 provides an angle of avoidance when the cutting part 500 is inserted into a surgical or surgical site.

In addition, the first bending bar 300 can be manufactured using metal such as stainless steel which is resistant to corrosion and has appropriate strength and elasticity.

The straight bar 200 and the first bending bar 300 are curved in a curved shape. The straight bar 200 and the first bending bar 300 are bent at the first bending part 210 By a curve.

That is, since the first bending bar 300 has a bent shape in the left or right direction, when the practitioner grasps the first bending bar 300 having a predetermined angle with the hand holding the joining part 100, It can be easily inserted into the treatment area of the joint.

Since the first bending part 210 has a curved line, it is possible to prevent the skin of the operation subject from being damaged by the bending part.

The second banding bar 400 may have a circular beam shape bent and extended at an angle larger than a right angle from the front end of the first banding bar 300 forward.

Here, the second bending bar 400 is connected to the first bending bar 300 so as to have the same central axis line as the longitudinal center axis line of the first bending bar 300.

The longitudinal center axis line of the second banding bar 400 is oblique to the longitudinal center axis line of the first banding bar 300.

At this time, it is preferable that the longitudinal central axis line of the second banding bar 300 has a vertical center axis line of the first banding bar 300 and an inclination angle within a range of 110 to 130 ° (degrees).

Since the second banding bar 300 has an inclination angle within the range of 110 to 130 degrees, the front end tooth 520 and the side end tooth 530 of the cutting portion 500, which will be described later, Lt; / RTI >

Thus, the jaw joint can be easily cut without a large adjustment of the handling angle in the state where the practitioner grasps the handpiece 10.

In addition, the second banding 400 can be manufactured using a metal such as stainless steel which is strong against corrosion and has appropriate strength and elasticity.

The straight bar 200 and the first and second bending bars 300 and 400 are formed such that the diameter of the linear bar 200 gradually decreases from the front end of the coupling part 100 to the rear end of the cutter 500 .

That is, since the joining portion 100 of the straight bar 200, the first and second bending bars 300 and 400 has a tapered shape, the diameter of the portion substantially inserted into the jaw joint treated region Can be formed small.

It is also preferable that the straight bar 200 is longer than the first banding bar 300 and the first banding bar 300 is longer than the second banding bar 400.

That is, the straight bar 200 provides a length in which the cutting portion 500, which will be described later, can reach the inside of the jaw joint.

The first banding bar 300 provides a length that the cutting part 500 to be described later can reach to the inside of the jaw joint and at the same time the interference from the contour of the jaw joint when the cutting part 500 enters the jaw joint (Avoiding) a bending angle.

In addition, the second banding bar 400 provides a bending angle at which the outer surface of the jaw joint can be in contact with the cutting part 500, which will be described later, and the first and second banding bars 300, The operation angle of the operation unit 400 is varied.

At this time, when cutting angles of the first and second banding bars 300 and 400 are varied, the cutting direction of the cutting portion 500 can be changed.

As described above, since the length of the straight bar 200 is longest and the length of the bent first banding bar 300 is long, interference between the coupling portion 100 and the surrounding skin can be reduced, The portion 500 can be deeply inserted into the treatment site.

Since the second bending bar 400 has a bent shape in the left or right direction, the second bending bar 400 having a certain angle may be inserted into the jaw 100 while the operator grips the joint part 100 by hand. So that it can be inserted and positioned easily along the external shape of the joint.

The cutting portion 500 is coupled to the front end of the second banding bar 400, and a plurality of cutting teeth are formed at the front end and both end portions of the cutting portion 500, respectively.

5 to 7, a body 510, a front end saw tooth 520, and a side end tooth 530 are formed on the cutting portion 500.

The body 510 is flatly coupled to an extended end of the second banding bar 400 and the body 510 is formed such that the width W1 in the forward and backward direction is wider than the width W2 in the transverse direction .

That is, the body 510 has a thin upper and lower thickness so that it can be easily inserted into the jaw joint of the subject, and the width W2 of the body 510 in the transverse direction is smaller than the width W2 of the second banding bar 400 And may have a width greater than the shear diameter.

As described above, since the body 510 has a rectangular shape with a narrow width, it is possible to minimize the interference between the both sides of the body 510 and the operation part when the operator holds the handpiece 10.

The rear end of the body 510 is formed with a tapered portion 550 so that the rear end of the body 510 can be gradually narrowed with the front end of the second banding bar 400.

The tapered portion 550 extends gradually toward the rear of the body 510 and the rear end of the tapered portion 550 is integrally coupled to the front end of the second banding bar 400.

The tapered portion 550 prevents the rear end of the body 510 connected to the second banding bar 400 from protruding outward.

In addition, the front end of the body 510 may have a shape of a fan, a semicircle, or an ellipse along the side.

The shear teeth 520 are formed along the front end of the body 510 and exert a cutting force by the ultrasonic vibration transmitted from the body 510.

Here, the front teeth 520 have a function of cutting the jaw joint by the ultrasonic vibration transmitted to the body 510 through the second banding bar 400.

A plurality of the front teeth 520 may be arranged adjacent to each other along the lateral direction. The front teeth 520 may be arranged in the same size and shape so as to be adjacent to the front end of the body 510 along the lateral direction .

In addition, the front teeth 520 may have the same size and shape as each other, and the front teeth 520 may have an equilateral triangle shape.

At this time, the ends of the front teeth 520 and the side teeth 530, which are arranged at the front end of the body 100, may have any one of a fan shape, a semicircle shape, and an ellipse shape.

The side tooth 530 is formed along the side edge of the body 510 and exerts cutting force by ultrasonic vibration transmitted to the body 510 through the second banding bar 400.

The side-toothed tooth 530 has a function of cutting the jaw joint together with the above-described front teeth 520 by ultrasonic vibration.

The side teeth 530 may be arranged to be adjacent to each other along the lateral direction. The side teeth 530 may protrude from both sides of the body 510 at two sides.

The side teeth 530 may have the same size and shape as those of the side teeth 530, and the side teeth 530 may have an equilateral triangle shape.

Particularly, the end tips of the side teeth 530 and the front ends of the front teeth 520 may have a shape of a fan, a semicircle, or an ellipse.

That is, since the front teeth 520 and the side teeth 530 form a continuous curve, the treatment surface of the jugular vein can be continuously cut according to the direction of the operator's manipulation, Lt; / RTI >

The front end teeth 520 and the side end teeth 530 may have a shape gradually decreasing from the upper and lower surfaces toward the front end direction.

To this end, the upper and lower surfaces of the front teeth 520 and the side teeth 530 are formed with inclined cutting surfaces 540 so as to decrease in thickness toward the front end.

6 and FIG. 7, the cutting surface 540 may be formed to correspond to the upper and lower surfaces of the front end tooth 520 and the side end tooth 530, respectively.

Of course, the cutting surface 540 may be formed at an angle different from that of the upper surface of the front end tooth 520 and the side end tooth 530, if necessary.

That is, since the cutting surface 540 has a blade shape, the front teeth 520 and the side teeth 530 can cut the jaw joint more sharply.

It is preferable that the body 510, the front teeth 520 and the side teeth 530 described above are integrally formed and formed into a single body.

The main body 510, the front teeth 520, and the side teeth 530 can be used for most of the known molding processes (e.g., injection molding of metal powders, etc.).

The body 510, the front teeth 520, and the side teeth 530 may be made of a variety of metal materials having good durability, wear resistance, and comfortability.

For this purpose, the material of the body 510, the front teeth 520 and the teeth 530 may be made of stainless steel or titanium-based alloy, which has good strength and is resistant to moisture.

As described above, since the cutting portion 500 is integrally formed of stainless steel or titanium material resistant to moisture, it has a long life and can provide a high cutting force in the jaw joint surgery.

As a result, according to the present invention, the first bending bar 300 is bent at an angle similar to the left-right direction of the jaw joint, and the second bending bar 400 is bent to form the front end tooth 520 of the cutter 500, And the side teeth 530 toward the surgical or surgical site.

Thereby, it is possible to reduce the interference with the jaw joint during the procedure, and the operator does not have to adjust the handling angle greatly, so that convenience of operation or surgery can be ensured.

The body 510 of the cutting part 500 is formed in a thin plate shape by a shape in which the diameter gradually decreases from the straight line 100 to the cutting part 500, The cutting portion 500 can be easily inserted.

By arranging the front teeth 520 and the side teeth 530 of the cutter 500 in a shape such as a sector shape, a semicircle, an ellipse, etc., the side of the jaw joint can be continuously cut along the handling direction of the practitioner, Performance can be improved.
