Description

Handpiece with Burr Guide

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for cutting teeth used to delete teeth, and more particularly to a handpiece having a bur guide. It is for a handpiece that can more precisely and facilitate tooth removal without this reduction.

In general, in order to repair a lost tooth, it is common to remove a tooth used as a preparation tooth and attach a crown to the tooth preparation deleted by a metal material or a ceramic material and connect and fix it with an artificial tooth.

In the case of the tooth removal for the conventional crown, crown bridge, laminate, splint, etc., the quality of the deletion was inevitably caused by the skill of the operator. And the type and extent of deletion required by the prosthesis could not be accurately determined. In some cases, too many hemorrhoids may be removed, resulting in neurotherapy or hypersensitivity after the final prosthesis restoration.

In this regard, the inventors of the present invention through the Republic of Korea Patent Publication 2012-0053457 (name of the invention: tooth deletion guide device), the induction device support that is fixed to the teeth in the form of covering the part or all of the teeth, gums or alveolar bone, and teeth Tooth removal guide device including a tooth removal guide for guiding a cutting machine for deletion has been developed. That is, in the tooth deletion guide device for deleting a desired portion and a desired shape of a tooth or alveolar bone, the tooth deletion guide device includes a deletion guide hole portion accommodating the cutter along a movement path of the cutter, and along the removal guide hole portion. A tooth deletion guide unit formed in contact with the cutter and including a tooth deletion guide for inducing a movement path of the cutter; And an induction device support unit fixed to the tooth, the gum or the alveolar bone in such a manner as to cover a part or all of the tooth, the gum or the alveolar bone so that the tooth deletion guide device does not move when the tooth is deleted. I have developed a device.

As shown in FIG. 1, the handpiece 1 having the conventional cutting machine used in the tooth removal guide device deletes the teeth by the rotation of the burr 2 having the stopper 31 on the surface. That is, the burr 2 is composed of a connecting portion 21 connected to the handpiece head 11, a cutting portion 22 for cutting teeth and a stopper 31 formed on the surface, as shown in FIGS. The tooth is removed by the rotation of the cutting unit 22. Here, the stopper 31 guides the handpiece 1 to move along the movement path while moving while being in contact with the tooth removal guide surface of the tooth removal guide device.

In the case of deleting the tooth using the conventional handpiece 1, in order to guide the burr 2 mounted on the handpiece 1 to the portion to be deleted, the handpiece 1 is held by the hand and the burr 2 is removed. To be induced, due to the shaking of the hand holding the handpiece (1) was often the case of the removal of the tooth was not desired, the deletion site and the amount of deletion was also incorrect.

In the case where the stopper 31 as the guide portion is formed on the surface of the burr 2 itself, the stopper 31 moves along the tooth removal guide surface and friction with the guide surface causes the stopper 31 to face the burr 2. Frequent decreases in torque and removal force occur.

Handpiece having a burr guide member.

Here, the tooth deletion guide includes a movement path through which the handpiece moves, and the handpiece deletes teeth by rotation of the burr while moving along the movement path.

Further, it is more preferable that the burr guide member maintain a predetermined distance from the burr around the burr.

In addition, the induction member can be separated and coupled to the head of the handpiece.

In addition, the derivation member may surround the top or the top and the middle of the burr.

In addition, the derivation member preferably has a rotatable ball (ball) on the inner surface.

The present invention shown here is made in the handpiece 1 for deleting a tooth along the tooth deletion guide 131, including a burr 2 and a burr guide member (3).

First, the present invention relates to a handpiece 1 for deleting a tooth along the tooth deletion guide 131. The tooth deletion guide 131 may be a structure in which a movement path of a device for deleting a tooth is previously included or a surface thereof, and the present invention may be a device for deleting a tooth while moving along the movement path ( See FIG. 4). That is, the present invention may be a cutting machine for tooth deletion, and may be used with a tooth deletion guide device including a tooth deletion guide unit or a tooth deletion guide 131 for guiding such a cutter. For example, as shown in the Republic of Korea Patent Publication No. 2012-0053457, it may be used or included with the tooth deletion guide device including a tooth deletion guide surface 131 to guide the movement path of the cutting machine. However, the handpiece 1 according to the present invention is not limited thereto, but may be any kind of cutting machine for deleting a tooth along a path in which the handpiece 1 moves.

Here, the handpiece 1 according to the invention basically comprises a burr 2 rotatably mounted to the head 11 of the handpiece 1. As shown in FIG. 7, the burr 2 includes a connection part 21 connected to the handpiece head 11 and a cutting part 22 for cutting teeth, and the connection part 21 and the cutting part 22. It is sufficient to have, and the stopper 31 does not need to be formed on its surface as in the prior art. The burr 2 may delete the tooth by the rotation of the cutting unit 22, the handpiece 1 according to the present invention is moved along the movement path of the tooth deletion guide 131, the burr 2 ) Is to remove the tooth by the rotation. To this end, the handpiece 1 may include a motor, etc. coupled with the burr 2 to rotate the burr 2.

In addition, the present invention is a handpiece having a bur guide, and is particularly characterized by having a bur guide member 3. The burr guide member 3 surrounds a part of the burr 2 without contacting the burr 2 from the head 11 of the handpiece 1. That is, as shown in FIG. 8, the burr guide member 3 has the burr 2 in the center of one side of the head 11 of the handpiece 1, and the periphery of the burr member 3 does not come into contact with the burr 2. It has a surrounding shape. It is preferable that such a induction member 3 surrounds the upper end or the upper end and the middle of the burr 2, because the lower end of the burr 2 is exposed to the outside to remove the tooth. Then, the burr 2 is positioned inside the burr guide member 3, and the burr 2 is not in contact with the inner surface of the burr guide member 3 as much as possible without the head 11 of the handpiece 1. Is coupled to one side. Thus, since the burr guide member 3 according to the present invention maintains a predetermined distance from the burr 2 around the burr 2, the burr guide member 3 is rotated even if the burr 2 rotates. The tooth can be removed while rotating continuously without contacting it. Along with this, the derivation member 3 may be integrated into the head 11 of the handpiece 1, but it may be separated and combined for the convenience of exchange and repair.

In addition, the induction member 3 according to the present invention is characterized in that a stopper 31 corresponding to the tooth removal guide 131 is formed on its outer surface. The stopper 31 moves along the tooth removal guide 131 as shown in FIG. 8, thereby inducing the handpiece 1 according to the present invention to follow the intended path, thereby reducing the It may be a burr induction site for inducing the direction of movement. The stopper 31 preferably has a shape corresponding to the tooth induction guide 131, so that the derivation member 3 does not escape to another place when the tooth guide member 3 moves along the tooth deletion guide 131. It is possible to precisely follow the tooth removal guide 131. That is, the stopper 31 may be formed in the shape or sphere, hemispherical shape, circular shape, semicircular shape, cylindrical shape, funnel shape, etc. on the whole or part of the induction member 3, one or more can be formed (See FIGS. 9 and 10). Then, the handpiece 1 having the induction member 3 according to the present invention does not deviate along the tooth induction guide 131, even when moving through the curved portion or when moving up and down the tooth induction guide. Follow 131 accurately and easily.

The present invention has a burr guide member 3 that surrounds the burr 2 separately from the burr 2 that is mounted on the handpiece 1 and rotates, so that the rotational force of the burr 2 does not decrease. There is an effect that can maximize the rotational force and the elimination force of (2). That is, conventionally, since the stopper 31 formed on the burr 2 itself is in contact with the tooth removal guide surface 131, the rotational force and the removal force of the burr 2 are drastically reduced during the movement, but the present invention provides a burr ( 2) Since the guide surface (that is, the stopper 31) leading to the guide 2 and the engaging portion of the burr 2 or the burr 2 does not directly contact, the rotational force and the removal force of the burr 2 are not reduced. Can be deleted. In the present invention, since the rotating bur 2 rotates without touching the tooth induction guide 131, a friction force does not occur between the bur 2 and the tooth removal guide 131, and thus It can have the same rotational force and removal force as the tooth removal without the guide surface. In other words, the stopper 31 according to the present invention is formed on a separate derivation member 3 rather than the burr 2, so that the handpiece 1 according to the present invention is induced by the stopper 31. The surface 131 can be stably moved, and at the same time, the burr 2 can maintain a high rotational force and a removing force without being stuck or blocked by the stopper 31.

Furthermore, according to the present invention, when the derivation member 3 moves along the tooth deletion guide 131, no part of the bur 2 is in direct contact with the tooth deletion guide 131. Therefore, the rotational force and the removal force of the burr 2 hardly occur. That is, even if the friction induction member 3 according to the present invention touches the tooth removal guide surface 131 to some extent, friction is induced by holding the handpiece 1 by hand and applying a predetermined force. Since the (3) can be continuously moved along the tooth induction guide 131, the burrs (2) due to the friction between the contact area between the tooth removal guide 131 and the induction member (3) Rotational force and tooth removal are not significantly reduced.

9 is a side view and a cross-sectional view for explaining that the induction member 3 can be rotated in the handpiece 1 having the induction member 3 according to an embodiment of the present invention, and FIG. The side view and sectional drawing for demonstrating that the stopper 31 of the integral type | mold in which the induction | guide_body 3 is fixed to the handpiece head 11 part, and the stopper member 3 of the induction | guide_body 3 are various shapes.

First, the induction member 3 according to the present invention may be coupled to the handpiece 1 or its head 11 portion in various forms and methods. That is, the induction member 3 may be integrally formed and fixed from the portion of the handpiece head 11 (see FIG. 10), and may be rotatably mounted to the head 11 of the handpiece (see FIG. 10). 9).

Here, the present invention may further include a bearing included in the head 11 of the handpiece and coupled to the induction member 3 to manually rotate the induction member 3, and the burr. It is also possible to further include a motor for automatically rotating the induction member (3).

For example, when a part of the handpiece head 11 is formed into a bearing shape, a cylinder shape, another shape, or the like, and the coupling induction member 3 corresponding thereto is connected, the induction member 3 is the handpiece head. While rotating on (11), it is possible to move along the tooth removal guide 131. That is, since the derivation member 3 moving along the tooth deletion guide 131 can rotate on the handpiece head 11, the stopper 31 formed on the derivation member 3 is the tooth deletion. It may move while being in contact with the guide surface 131.

Then, it is possible to move the reed induction member 3 significantly more easily than when it is fixed to the handpiece head 11. That is, in the present invention, since the induction member 3 can rotate manually or automatically separately from the burr 2, the handpiece 1 can move more smoothly along the tooth removal guide 131. Therefore, tooth deletion can be made more accurate and easier.

At this time, the rotation of the induction member 3 may be rotated by the force of the handpiece 1 by the user's hand, or may be automatically rotated by a separate electric force such as a motor.

In addition, the rotation of the induction member 3 is preferably made separately from the rotation of the bur 2, the direction or intensity of rotation may also be the same or different from the rotation of the bur (2).

11 and 12 are side views and cross-sectional views for explaining that the stopper 31 of the derivation member 3 according to the present invention is rotatable, respectively, and the stopper 31 according to the present invention is also a derivation member 3. It is possible to rotate separately.

That is, the stopper 31 may also be rotated regardless of whether or not the versatile member 3 is rotatable. To this end, the induction member 3 may further include a bearing or a motor, which is coupled to the stopper 31 and rotates the stopper 31 manually or automatically while being included therein.

As shown in FIGS. 11 and 12, it is also possible for a part of the induction member 3 fixed to the handpiece head 11 to rotate. Then, it is possible to move the reed induction member 3 significantly more easily than when it is fixed to the handpiece head 11.

FIG. 13 is a cross-sectional view illustrating a structure in which a ball is provided inside the induction member 3 in the handpiece 1 having the induction member 3 according to an exemplary embodiment of the present invention. Another feature of the invention shown is that the induction member 3 has a ball 32 rotatable on its inner surface.

It is preferable that the inner surface of the induction member 3 does not come into contact with the burr 2 as much as possible. However, in case of contact, the rotatable ball 32 is provided inside the induction member 3 as described above. Even if a part of the burr 2 is touched, it is advantageous in that it can be subjected to less resistance than touching the burr inducing member 3.

To this end, it is more preferred that the ball 32 is basically separated from the burr 2, so that the burr 2 is in contact with the rotatable ball 32 in this manner, thereby preventing the burr 2 from shaking. In addition, it is possible to minimize the reduction of the rotational force and the removal force of the burr 2, as well as to enable stable tooth removal.

14 is a side view and a cross-sectional view for explaining a state in which the induction member 3 is coupled to the handpiece head 11 in the handpiece 1 having the induction member 3 according to an exemplary embodiment of the present invention. to be.

As described above, the induction member 3 according to the present invention may be integrated into the head 11 of the handpiece 1, but it is also possible to be separated and combined. That is, the induction member 3 may be manufactured while being attached to the handpiece head 11 from the beginning, and a portion where the induction member 3 is attached to a kind similar to the existing handpiece 1 is attached or detached. It can be made into a form that can be attached and used only when necessary. The method or form of coupling of the induction member 3 is not particularly limited, and includes all of those known in the art.

For example, in the case of the detachable type, the part including the induction member 3 may be formed in various forms such as a ligation type, a clip type, an insert type, a forced fit type, and can be attached and detached only when necessary for the handpiece head 11. have. For example, in FIG. 14, the coupling part 33 of the portion including the induction member 3 is coupled to the handpiece connecting groove 111.

In the case of the detachable type, there is an advantage in that replacement or repair is easy, but in this case, it is important to prevent the induction member 3 from being detached from the handpiece 1. To this end, the present invention can also be used as a fixing portion for fixing the induction member 3, not the shaft portion of the handpiece 1, but the handpiece head (11).

15 and 16 respectively show that the extension part 34 of the induction member 3 is coupled by the coupling means 341 in the handpiece 1 having the induction member 3 according to the preferred embodiment of the present invention. The perspective view and sectional drawing for demonstrating the state joined to the handpiece head 11 are shown.

As shown here, another feature of the present invention has a shape in which the extension portion 34 provided with the induction member 3 surrounds a part of the handpiece head 11. That is, the extension part 34 has an internal shape corresponding to the outer shape of the handpiece head 11, and includes the whole or a part of the handpiece head 11 therein, so that the inductive member 3 is formed. Can be firmly fixed to the handpiece head 11.

In addition, a part of the handpiece head 11 may be fixed by a coupling means 341 such as a separate cover or support having a female thread or a male thread.

17 and 18 are side views and use state diagrams for explaining that the stopper 31 is the induction member 3 in the handpiece 1 having the induction member 3 according to the preferred embodiment of the present invention, respectively. Another feature of the present invention is that the stopper 31 itself is the induction member 3, or a portion of the handpiece head 11 is the stopper 31 and / or the induction member 3. .

When the tooth is deleted using the handpiece 1 provided with the stopper 31 and / or the induction member 3 as in the present invention, the handpiece 1 may have various paths such as vertical, horizontal, or curved. In some cases, when the path is an angular shape or a plate shape, it may be difficult to accurately and easily rotate and move the stopper 31 having a convex shape in the angular portion or the like. For example, if the diameter of the handpiece head 11 is generally larger than the diameter of the induction member 3 and / or the stopper 31 attached thereto, it is necessary to delete the peripheral surface of the tooth having a smaller diameter ( That is, when the gap between the tooth deletion guide surface 131 is close), the stopper 31 may be engaged, and thus rotational movement may be difficult.

In this case, as shown in Figs. 17 and 18, the stopper 31 itself according to the present invention consists of the induction member 3, or a part of the handpiece head 11 is a stopper 31 and / or When the burr guide member 3 is formed, the size of the stopper 31 and / or the burr guide member 3 can be made relatively small, whereby a finer path can be moved.

19 is a view illustrating the formation of a hole for discharging water or foreign substances on the surface of the induction member 1 in the handpiece 1 having the induction member 3 according to an exemplary embodiment of the present invention. Side view and cross section for.

According to the present invention, when the burr 2 mounted on the handpiece 1 rotates and the tooth is deleted, water may be injected from the end of the handpiece head 11, and water is injected from the induction member 1. It is also possible. To this end, the induction member 3 may further include a water injection port, in this case can more effectively cool the heat generated from the bur (2).

In addition, the induction member 3 may have a hole (hole) through which water or foreign matter is discharged. As such, when a plurality of holes are formed in the whole or part of the induction member 3, the water sprayed from the handpiece head 11 and the induction member 3 may be more easily infiltrated into the tooth when the tooth is deleted. They can also easily drain the debris from the removal of teeth.

On the other hand, while the present invention has been shown and described with respect to certain preferred embodiments, the invention is variously modified and modified without departing from the technical features or fields of the invention provided by the claims below It will be apparent to those skilled in the art that such changes can be made.
