Hereinafter, embodiments of the present invention will be described with reference to the drawings.

FIG. 1 is a schematic perspective view of an implant drill according to an embodiment of the present invention, and FIG. 2 is a cross-sectional view of the implant drill of FIG. 1 taken along line A-A'.

Hereinafter, an implant drill according to an embodiment of the present invention will be described with reference to FIGS. 1 and 2.

1 and 2, the implant drill is connected to a drill unit 300 having a cutting edge, a power unit 400 for supplying rotational force to the drill unit 300, and the power unit 400, and vertically A movable drill body 200, a support fixing part 100 connected to at least one end of the drill body 200, and a control unit 500 that controls the vertical movement of the drill body 200 and the power of the power unit 300 ). In addition, the support fixing part 100 is formed in an inverted U-shape in a vertical cross-sectional shape, and includes a cavity 90 formed as an empty space inside so as to penetrate without contacting when the drill part 300 moves up and down. Characterized in that.

Since the drill part 300 is provided with a cutting edge, it is possible to perforate the alveolar bone of a patient (a person to be treated). The cutting edge of the drill part 300 may be formed of a material such as metal or alloy. The drill unit 300 drills a hard alveolar bone by a rotational motion and can perform a rotational motion by a rotational power transmitted from the power unit 400, and includes the shape of a cutting edge of various methods well known in the art. I can.

The power unit 400 performs a function of providing rotational power to the drill unit 300, and a rotational force (ie, rotational rpm) is controlled by a control unit 500 to be described later, or on/off Can be controlled. In order to transmit the rotational power of the power unit 400 to the drill unit 300, the power unit 400 and the drill unit 300 may be connected to each other. However, the meaning of being connected means that the power unit 400 and the drill unit 300 may be connected in a state with a different configuration interposed therebetween, and the drill unit by the rotation power of the power unit 400 Anything is possible as long as 300 is capable of rotating.

The drill body 200 can be moved up and down while being connected to the power unit 400. Meanwhile, in the present invention, the meaning of "up and down" may mean a direction in which the drill part 300 goes toward the patient's gums or a direction away from the patient's gums based on the patient's (the subject)'s gums. The drill body 200 may be fixed and connected to the power unit 400 so that the power unit 400 moves only up and down during a procedure. Accordingly, when the operator majors in the alveolar bone using an implant drill, it is possible to prevent the alveolar bone from becoming wider than necessary.

In addition, since one end of the drill body 200 and the support fixing part 100 are connected, it is possible to prevent shaking in the left and right directions when using an implant drill to be described later. The drill body 200 and the support fixing part 100 allow the drill body 200 to move up and down, and the support fixing part 100 is provided with hydraulic pressure between the drill body 200 and the support fixing part 100 so as not to move. Up and down movement may be possible by the same method or only up and down movement may be possible by a sliding method, and the method is not particularly limited to any one.

The support fixing part 100 is formed in an inverted U shape in a vertical cross-sectional shape, and includes a cavity 90 formed as an empty space inside so as to penetrate without contacting when the drill part 300 moves up and down. As the vertical cross section of the support fixing part 100 is formed in an inverted U shape, a part of the support fixing part 100 is seated on the exposed gum of the patient, thereby preventing the implant drill from moving undesirably during the drilling process. In other words, in the implant drill according to the present invention, the vertical cross section of the support fixing part 100 is formed in an inverted U-shape, placing it on the gums of the patient's perforating part, and being connected to the support fixing part, it moves only in the vertical direction. The body 200, and the power unit 400 and the drill unit 300 connected to the drill body 200 move up and down together with the up and down movement of the drill body 200, thereby supporting support without moving with only one implant drill. While, by moving the drill unit 300 in the vertical direction, it is possible to drill at an accurate position.

On the other hand, the support fixing part 100 includes a cavity 90 formed as an empty space inside so that it can penetrate without contacting when the drill part 300 moves up and down, so that the drill part 300 is in the alveolar bone of the patient. You can prevent it from getting in the way of drilling

More specifically, the support fixing part 100 has a first support part 110 curved downward from one side of the cavity 90, and downward from the other side of the cavity 90. Including a curved second support portion 120, the first support portion 110 and the second support portion 120 may be characterized in that symmetrical to each other.

Although not shown separately, the inverted U-shaped part of the support fixing part 100, that is, the lower part of the first support part 110 and the second support part 120 in contact with the patient's gums, is made of silicone to prevent damage to the patient's skin. It may be composed of a material or the like, or may be configured to replace it for hygiene.

Meanwhile, the control unit 500 controls the vertical movement of the drill body 200 and the power of the power unit 300. The control unit 500 controls the drill body 200 to move downwards only up to a predetermined distance, and when the drill body 200 completes the movement to a specific distance, it is controlled to rise upward again, or the power unit 300 Can be made to stop working. Alternatively, the drill body 200 moves downward only until it reaches a specific position, and when it reaches a specific position, the drill body 200 is moved upward or the operation of the power unit 300 is stopped. I can. Without limitation, it is possible to minimize damage to the alveolar bone of the user by appropriately adjusting the vertical movement of the drill body 200 and the rotation rate (rotation speed) of the power unit 300.

Meanwhile, referring to FIG. 2, the drill part 300 includes a first detection part 310 at an end, the support fixing part 100 includes a second detection part 150, and the control part 500 The drill body 200 and the power unit 400 may be controlled by sensing between the first detection unit 310 and the second detection unit 150.

The first detection unit 310 and the second detection unit 150 interlock with each other to detect each other's positions, thereby confirming where the end of the drill unit 300 is located. By controlling this by the control unit, You can precisely perforate the alveolar bone. As a preferred example, the first detection part 310 includes a first magnetic material formed of a magnetic material, and the second detection part 150 is provided on at least one of the first support part 110 and the second support part 120. And a second magnetic body formed of a magnetic material, and the control unit 500 may sense a position of the drill part by a magnetic force between the first magnetic body and the second magnetic body.

When the drill part starts to perforate the patient's gum 10, it is difficult to confirm from the outside to what position the drill part has progressed with the naked eye. The second detection unit 150 formed by magnetic force recognizes the distance between each other, so that it is possible to know how much the position has been reached, and the exact position can be recognized even without visually checking. Accordingly, the controller 500 can accurately control the vertical movement of the body portion 200 and the rotational force of the power portion 400 based on this.

On the other hand, it may be characterized in that it further comprises a position control unit 50 capable of adjusting the position of at least one of the first magnetic body and the second magnetic body in the vertical direction. The position of the second detection unit 150 formed on at least one of the first support unit 110 and the second support unit 120 by the position control unit 50 and formed of a second magnetic material made of a magnetic material. Since it can be adjusted vertically, the depth of the perforation can be easily adjusted according to the characteristics of the patient or the location to be perforated. In the case of the second detection unit 150, since the position of the second detection unit 150 can be adjusted in an external visually recognized space, a desired depth of perforation is set in advance, and the first detection unit 310 of the drill unit 300 drills to a desired position. In this case, the control unit 500 recognizes that the drill unit 300 has reached the desired position due to mutual magnetic force with the second detection unit 150, and the drilling can be finished. Therefore, even if not visually checked from the outside, the drill part can be drilled to the correct depth by the magnetic force between the first detection part 310 and the second detection part 150. In addition, according to the implant drill of the present invention, the exact position of the drill part can be determined only by a simple process of forming a magnetic material (for example, a magnet) on one of the end of the drill part and one of the first support part 110 and the second support part 120. Since the implant drill can be manufactured, the manufacturing cost and manufacturing method are very simple.

Each of the first detection part 310 and the second detection part 150 may be located inside the distal end of the drill part 300, and at least one of the first support part 110 and the second support part 120 It may be located inside one or more. Without limitation, the position of the first detection unit 310 may be adjusted as necessary.

Meanwhile, FIGS. 3 to 5 are cross-sectional views schematically showing a process of performing an implant drill on the gums of a patient (patient) using an implant drill according to an embodiment of the present invention.

With reference to Figures 3 to 5 will be described in more detail for the operation method of the implant drill of the present invention.

As shown in FIG. 3, the drill part 300 may start rotating while the body part moves in the direction of the patient's gum 10 on the lower side by the control part 500, and as shown in FIG. 4, the distal part of the drill part 300 When the first detection unit 310 including the first magnetic material formed of magnetic material reaches the position H where the second detection unit 150 including the second magnetic material formed of magnetic material is formed, the positions of each other are sensed. The controller 500 may recognize this and stop drilling. Next, as shown in FIG. 5, by stopping the rotation of the drill part 300 and moving the drill body to the upper end, the drill part 300 moves in a direction away from the patient's gums to complete the perforation 20.

Meanwhile, FIG. 6 is a cross-sectional view of an implant drill according to another embodiment of the present invention.

Referring to FIG. 6, the implant drill may further include suction units 131 and 141 formed in the vicinity of the cavity of the support fixing unit 100 and suck a material in the vicinity of the cavity. That is, the suction parts 131 and 141 may be formed at positions adjacent to the cavity of the first support part 110 and the second support part 120 of the support fixing part. The suction units 131 and 141 are configured to perform perforation by sucking in foreign matters, residues that may occur during the perforation process, and crushed alveolar bone when the drill unit 300 performs perforation in the vicinity of the cavity. You can make the location more clean and make the perforation more precise. In the implant drill of the present invention, the support fixing part is supported by the user's gums to prevent unnecessary vibration of the drill part in the process of performing the perforation, while forming suction parts 131 and 141 in the vicinity of the support fixing part in contact with the gums. It can prevent as much as possible from being affected by etc. Meanwhile, although not shown separately, the suction units 131 and 141 may be connected to other components to form a connection unit for discharging foreign substances sucked from the suction units 131 and 141 to the outside.

On the other hand, Figure 7 is a cross-sectional view of an implant drill according to another embodiment of the present invention.

Referring to FIG. 7, the implant drill includes a second position adjusting part that adjusts the position of the second magnetic body 150 up and down, and the second position adjusting part is exposed to the outside so that it can be controlled from the outside of the support fixing part. It may be characterized in that it includes an external terminal (170). The external terminal 170 allows the user to adjust the position of the second magnetic body 150 from the outside, and finally, the depth at which the drill part 300 should be drilled. In addition, the support fixing part may further include a guide line 160 that allows the external terminal 170 to move up and down while being exposed to the outside.

In addition, the support fixing portion includes a transparent window 180 formed of a transparent material, and the transparent window 180 is formed on the first support portion 110 or the second support portion 120, and the transparent window 180 ), the second support part 120 or the first support part 110 located on the other side may be visually recognized. That is, not only the second detection unit 150 located inside the transparent window 180 is visually recognized, but also the part located on the other side is visually recognized and when the implant drill is used, the patient's gums are removed by the transparent window 180. Can be seen. Therefore, while looking at the patient's gums, the position of the second magnetic body 150 can be adjusted using the external terminal 170, and the second magnetic body 150 can be positioned at a desired position by the operator using the implant drill. The second magnetic body 150 adjusts the depth of drilling of the drill part 300 by magnetic force with the first magnetic body 310 of the drill part 300. It can be determined while checking with the naked eye, making it more accurate and easier to set up the fabrication diagram.

On the other hand, at the periphery of the guide line 160, it may be characterized in that the external terminal 170 further includes a measuring scale (not shown) capable of measuring a moving distance in a specific numerical unit. Accordingly, by moving the external terminal 170 by a specific value, the position of the second magnetic body 150 can be more precisely adjusted, and as a result, the movement of the drill unit 300 can be controlled to precisely control the drilling process. have. In addition, in order to make this more precise, it may be characterized in that it further comprises a stopper (not shown) that enables the external terminal 170 to move and stop in the specific numerical unit in accordance with the weighing scale (not shown). .
