Specifically, the connecting body 120 extends the cutting body 130 connected to the other end by a predetermined length with one end fixed to the handpiece coupling body 110 to maintain the bent posture at a set angle. does it

For example, the connection body 120 may be configured to include a plurality of connection bars 121 and 123 having a relatively reduced outer diameter compared to the handpiece coupling body 110 .

In other words, the connection body 120 may be provided in a form in which a plurality of connection bars 121 and 123 are bent at a predetermined angle (a1, see FIG. 2 ).

As a specific example, the connecting body 120 includes a first connecting bar 121 and a second connecting bar 123 .

The first connecting bar 121 is a bar-shaped member made of a rigid material having a circular cross section connected to the handpiece coupling body 110 by a first set length. For example, the first connecting bar 121 may use a metal material harmless to the human body or a similar high-strength composite material.

The second connecting bar 123 is a bar-shaped member made of a rigid material having a circular cross section that is connected to a second set length between the first connecting bar 121 and the cutting body 130 . For example, the second connecting bar 123 may use a metal material harmless to the human body or a similar high-strength composite material.

For example, the first connecting bar 121 and the second connecting bar 123 may have a bent shape at a set angle (a1, see FIG. 2 ).

Preferably, the angle (a1, see FIG. 2 ) between the first connection bar 121 and the second connection bar 123 may have an angle within the range of 110 degrees to 170 degrees.

If the angle (a1, see FIG. 2) between the first connecting bar 121 and the second connecting bar 123 is less than 110 degrees, the cutting body has an excessively bent shape with respect to the handpiece coupling body. , there may be disadvantageous disadvantages during the cutting operation to dig out the bones, and there is a disadvantage in that the possibility of external departure of the bones stored in the receiving groove portion 133 increases during the operation of scooping the cut bones.

On the contrary, if the angle (a1, see FIG. 2) between the first connecting bar 121 and the second connecting bar 123 exceeds 170 degrees, the handpiece coupling body 110 and the cutting body 1300 are As it has a structure that is connected so as to be almost straight, there is a disadvantage in controlling the posture of the handpiece during the cutting operation to dig up the bones, and furthermore, there is a disadvantage in performing the operation to scrape the bones.

Therefore, it is preferable that the angle (a1, see FIG. 2) between the first connection bar 121 and the second connection bar 123 has an angle within the range of 110 degrees to 170 degrees.

In the spoon-type ultrasonic surgery tip 100 according to an embodiment of the present invention, the connection body 120 includes a round connection part 125 together with the first and second connection bars 121 and 123 .

The round connection part 125 connects the first connection bar 121 and the second connection bar 123 to each other in an integrated structure with high structural strength while being bent at a set angle (a1, see FIG. 2 ).

As such, the round connection part 125 may have a structure integrally connected with the first connection bar 121 and the second connection bar 123 between them. Accordingly, while a predetermined bending angle a1 (refer to FIG. 2 ) is formed between the first connection bar 121 and the second connection bar 123 , a sharp corner or an angular portion may not be formed in the bent portion. Accordingly, it is possible to prevent the patient's body from being harmed during the operation by the remaining parts of the tip except for the cutting body 130, and to solve the structural problem in which a specific part is vulnerable or damaged by soft round processing. can

On the other hand, in the spoon-type ultrasonic surgery tip 100 according to an embodiment of the present invention, one end of the second connecting bar 123 is connected to the round connecting portion 125 , and the other end is connected to the rear end of the cutting body 130 . is connected

In this case, the outer diameter size of the second connecting bar 123 may be gradually reduced from one end to the other end.

For example, when the outer diameter of the first connecting bar 121 is D1, the outer diameter of one end of the second connecting bar 123 is D2, and the outer diameter of the other end of the second connecting bar 123 is D3, D2 may be equal to or smaller than D1, and D3 may be smaller than D2 (refer to FIG. 2). And, the outer diameter of the second connecting bar 123 may be gradually reduced from D2 to D3 as it goes from one end to the other.

Accordingly, various cutting operations such as a cutting operation to dig up a bone using the cutting body 130 connected to the other end of the second connection bar 123, a cutting operation to lift the bone, and a cutting operation to scrape the bone are performed. Therefore, the operation of the cutting body 130 can be checked and monitored more accurately, and the operator's field of view toward the bone to be operated is suppressed as much as possible from being blocked by the second connecting bar 123 during the operation to increase the surgical precision. There are advantages.

It refers to a cutting edge portion protruding from both sides 1312 of the upper edge region excluding the portion. The second blade-shaped portion 143 has the advantage of enabling lateral cutting processing of scooping or scraping the bone sideways using the side portions 1312 instead of the front portion 1311 of the spoon-shaped body portion 131. .

In addition to this, the first blade-shaped portion 141 may further include a first extension protrusion 142 . The first extension protrusion 142 may have a shape inclined upward at a predetermined angle a2 from the distal end of the protruding portion of the first blade-shaped portion 141 , that is, the protruding tip portion.

The first extension protrusion 142 improves the cutting force when scraping the bone using the first blade shape 141 located at the front end, that is, the front part of the spoon-shaped body portion 131, and spreads the scraped bone. It can increase the working efficiency during the cutting operation, and facilitate the operation of collecting the scraped bone toward the receiving groove portion 133 . Preferably, the first blade-shaped portion 141 and the first extension protrusion 142 preferably have relatively greater rigidity and strength than the spoon-shaped body portion 131, thereby causing wear and damage to the blade required for cutting. can prevent

In addition, the second blade-shaped portion 143 may further include a second extension protrusion 144 . The second extension protrusion 144 may have a shape inclined upward at a predetermined angle from the end of the protruding portion of the second blade-shaped portion 143 , that is, the protruding tip portion. Here, the inclined angle of the second extension protrusion 144 may be formed to correspond to the inclined angle of the first extension protrusion 142 .

The second extension protrusion 144 improves the cutting force when scraping bones using the second blade-shaped portions 143 located on both sides of the spoon-shaped body portion 131, and during cutting operation to scoop out the scraped bone. It is possible to increase the working efficiency and improve the working effect of collecting the scraped bones toward the receiving groove 133 .

Referring to FIG. 7 , the ultrasonic surgical device 1000 including a spoon-type ultrasonic surgical tip according to an embodiment of the present invention includes the aforementioned spoon-type ultrasonic surgical tip 100 and bone dust. It includes a suction unit 200 for sucking the.

The suction unit 200 may be disposed adjacent to the cutting body 130 , more specifically, to face the receiving groove in which the bone dust together with the bone is accommodated. The suction unit 200 sucks the bone dust accommodated in the receiving groove and blocks the mixing of the dust inside the body.

For example, the dust suction unit 200 may include at least one vacuum pump 210 , a suction unit main body 220 , a connection line 230 , and a switch valve 240 .

The suction unit main body 220 is disposed to face the receiving groove, and sucks the bone dust collected inside the receiving groove by using the negative pressure of the vacuum pump 210 . The connection line 230 connects between the vacuum pump 210 and the suction unit main body 220 . The switch valve 240 is provided on the connection line 230 and can open and close the suction of this dust.

For example, the suction unit main body 220 includes a plurality of suction holes 221 formed to face the receiving groove and spaced apart from each other at a set interval. The plurality of suction holes 221 may divide the entire area of the receiving groove into a plurality of suction areas, and may individually suck the dust in the divided areas. In addition, the plurality of suction holes 221 may be formed in the suction unit main body 220 to correspond to the particle size of the bone dust, thereby increasing the suction power of the bone dust and improving the removal performance of the bone dust.

As described above, according to the configuration and action of the present invention, it is possible to cut the cutting site from the bottom to the top or to scrape it, so there is an advantage in bone cutting.

In addition, a sharp and sharp blade shape is disposed at the front end and upper edge of the cutting body to improve cutting force during bone cutting.

In addition, a convex slip portion is disposed at the rear end and lower end of the cutting body, and a smooth slip surface is formed through the outer surface of the slip portion. there is this

In addition, at least one receiving groove is formed in the inner center of the cutting body, there is an advantage that the cut bone, that is, the bone (bone) can be scooped from the bottom up like a spoon.

In addition, even bone dust generated during bone cutting can be stored in the receiving groove and then removed, thereby preventing the bone dust generated during bone cutting from being mixed into the body.

In addition, by adding a bone dust suction unit for sucking and removing bone dust at a position facing the receiving groove, there is an advantage in that bone dust generated during bone cutting is prevented from being mixed into the body and the safety of the patient can be promoted.

As described above, the present invention has been described with reference to the illustrated drawings, but the present invention is not limited by the embodiments and drawings disclosed in the present specification. It is obvious that variations can be made.
