Description

Implant handpiece {IMPLANT HANDPIECE}

The present invention relates to an implant handpiece, and more particularly, to an implant handpiece that accurately defines the position and depth of a hole in a drilling process for forming a hole in the alveolar bone for implant surgery.

The implant is called an artificial tooth or a third tooth. Implant surgery is performed by inserting an artificial component made of an artificial root (fixture), an abutment (abutment) and a crown (crown) restoration.

In the implant surgery, a hole is formed in the alveolar bone using a handpiece for implant to fix the fixture of the implant inside the oral cavity. At this time, since the alveolar bone has nerve or blood vessels formed, it is most important to form a hole having a depth at an accurate position. To this end, in the conventional implant surgery, a guide plate for guiding a position where a hole is to be formed in the oral cavity is coupled into the oral cavity, and then drilling is performed at a position guided by the guide plate.

However, the conventional implant guide surgical method has a problem that it is difficult to use the drill in a narrow space such as a posterior portion by only entering a drill coupled to a handpiece into a guide template. Further, since the conventional guide plate guides only the approximate position, the drilling process for forming the hole must be totally dependent on the experience and the operation ability of the practitioner. In some cases, the position and direction of the hole may be shifted, There is a disadvantage that the depth is not constant.

The handle 110 may include a battery unit for supplying power to the implant handpiece 100, a driving unit for providing a driving force to the drill coupled to the implant handpiece 100, And a control unit for controlling the overall operation of the implant handpiece 100 according to the manipulation of the switch unit disposed on the outer surface of the implant handpiece 100.

One end of the handle 110 may be provided with connection means for fastening the connection unit 120 to the connection unit 120.

The connecting portion 120 may be a member detachably attached to the handle 110. For example, the connecting portion 120 may be screwed to the handle 110, but the connecting method of the connecting portion 120 and the handle 110 is not limited thereto and may be any of various joining methods Of course, it can be replaced by one.

In this case, when the connection part 120 is fastened to the handle 110, the connection part 120 may be extended to be bent in the vertical direction and the horizontal direction along the length direction of the handle 110. For example, when the connection part 120 is completely fastened to the grip part 110, the direction of the connection part 120 is extended in a three-dimensionally folded state in the leftward direction and the downward direction along the length direction of the grip part 110 Can be designed. When the connection part 120 is completely fastened to the handle 110, the direction of the connection part 120 is designed to extend in a three-dimensionally folded state in the leftward direction and the downward direction along the longitudinal direction of the handle 110 .

That is, the connecting portion 120 may extend leftward and downward, or right and downward along the longitudinal direction of the handle 110, and may be coupled to the handle 110 at a predetermined angle. Further, the connecting portion 120 may be provided in a plurality of units using the structural feature that the connecting portion 120 can be detachably attached to the handle 110. At this time, each of the connection portions 120 can be fastened to the grip portion 110 at different angles. The type of the connection part 120 and the specific shape in which the connection part 120 and the grip part 110 are fastened will be described later with reference to FIG. 2 to FIG.

As described above, one end of the connection part 120 is provided with a means capable of being fastened to the handle part 110, and the head part 130 may be extended to the other end of the connection part 120.

The head portion 130 may be coupled with a drill 140 for forming a hole in the alveolar bone during the implant surgery. In particular, when drilling for implant surgery, the head portion 130 may be inserted along the inner wall of a guide template (see 200 in FIG. 4) described later. To this end, the head part 130 may be composed of a head part 131 and a locking protrusion 132.

The head portion 131 extends from the other end of the connection portion 120 and may be formed in a cylindrical or cylindrical shape. The drill 140 is coupled to the head 131. The drill 140 is coupled to the head 131. The drill 140 is coupled to the head 131, The center axis of the drill 140 can be designed to be the same as the center axis of the drill 140.

In addition, the head 131 may extend and extend from the connection part 120 at a predetermined angle with the connection part 120. That is, in the implant handpiece 100 according to the present invention, the knob 110 and the joint 120 may be first bent so that the joint 120 and the head 130 are secondarily bent . At this time, the angle of flexion of the head (the head portion 131) and the connection portion 120 can be set at various angles according to the implant surgery environment.

The latching jaw 132 extends to the upper portion of the head 131 and may share the same central axis as the head 131. [ The stopping jaw 132 may protrude in the lateral direction of the head 131 from the top of the head 131. That is, the diameter of the latching jaw 132 may be larger than the diameter of the head 131. Accordingly, even if the head portion 131 of the head portion 130 enters into the guide hole formed in the guide template during the drilling process for forming the hole in the implant surgery, the engaging protrusion 132 is caught in the upper portion of the guide hole So that a hole having a predetermined depth can be generated. Specific details related thereto will be described later with reference to FIG. 5 to FIG.

FIGS. 2 and 3 are views showing a specific example of the connection portion 120 having different extension angles from the grip portion 110. FIG.

As described above, the implant handpiece 100 according to the present invention may be provided with a plurality of connection portions 120 to be engaged with the handle 110 at various angles. In the implant surgery, The connecting part 120 having an angle suitable for reaching the grip part 110 can be selected and the grip part 110 can be fastened.

For example, as shown in FIG. 2, the first connection part 121 extending from the handle 110 by a predetermined angle may be fastened. 2 (a), 2 (b) and 2 (c) are respectively a plan view, a side view and a front view of the implant handpiece 100 to which the first connection portion 121 is fastened.

As shown in the figure, when the first connection part 121 is completely fastened to the grip part 110, the first connection part 121 is oriented in the left and right directions along the longitudinal direction of the grip part 110, It can be designed to extend in a bent state. In other words, the first connection part 121 can be bent in the leftward direction by a first angle with respect to the longitudinal direction of the knob part 110, and can be extended in a downward direction by a second angle.

As another example, as shown in FIG. 3, the second connection portion 122 having an extension angle different from that of the first connection portion 121 may be fastened to the handle 110. 3 (a), 3 (b) and 3 (c) are respectively a plan view, a side view, and a front view of the implant handpiece 100 to which the second connection portion 122 is fastened.

As shown in the figure, when the second connection part 122 is completely fastened to the grip part 110, the direction of the second connection part 122 is three-dimensionally arranged rightward and downward along the longitudinal direction of the grip part 110, It can be designed to extend in a bent state. In other words, the second connection portion 122 can be bent in the rightward direction by a first angle with respect to the longitudinal direction of the knob portion 110, and at the same time by being bent by a second angle in the downward direction.

That is, in the implant handpiece 100 according to the present invention, the first connection portion 121 is fastened to the handle 110 during the implant surgery on the maxillary right and left mandibular left and right posterior teeth, In the implant surgery, since the first connection part 121 is separated and the second connection part 122 is used in combination, access to the treatment part can be facilitated.

The first connection part 121 and the second connection part 122 are merely one embodiment cited for convenience of explanation, and the number of the connection parts 120 is not limited to two. That is, the implant handpiece 100 according to the present invention may have three or more connecting portions 120 having different extending angles, and each connecting portion 120 may be designed to have a unique extending angle. Accordingly, the practitioner can selectively fasten any one of the connection portions 120 suitable for surgery according to the position and angle of the hole.

In the meantime, the implant handpiece 100 according to the present invention is characterized in that the head part 130 is directly inserted to a guide plate for guiding the hole forming position to a predetermined depth. In this connection, a detailed description will be made with reference to FIG. 4 to FIG.

4 is a view showing an example of a guide template.

The guide template 200 may cover the prosthesis and at least one actual tooth. The guide template 200 may be disposed at the implantation position of the implant and may cover at least one tooth exposed at and around the implantation site.

The guide hole 210 may be formed so as to extend from the upper portion of the guide template 200 at the placement position of the implant. That is, the guide hole 210 may be a member for guiding the position of the hole to be formed for the implantation of the implant. At this time, the shape of the cross section of the guide hole 210 may be formed to correspond to the shape of the cross section of the head portion 131. As described above, when the head portion 131 is formed in a cylindrical shape, the guide hole 210 may also be formed in a cylindrical shape.

In particular, the guide hole 210 may be formed with an opening 220 where a part of the outer circumferential surface is cut. As described above, the implant handpiece 100 according to the present invention is intended to insert the head portion 130 into the guide hole 210 when drilling. At this time, when the guide hole 210 is completely cylindrical, the head part 130 can not be inserted into the guide hole 210 due to the connection part 120 extending to the side surface of the head part 130. In order to prevent such a phenomenon, the guide hole 210 may have an opening 220 having a predetermined distance from the top to the bottom. The width of the guide hole 210 may be greater than the width of the connection part 120.

5 is a sectional view of the head 130 coupled to the guide hole 210 during implant surgery.

As shown in the figure, during the implant operation using the implant handpiece 100 according to the present invention, the head part 130 can be inserted into the guide hole 210 in the drilling process for forming the hole. In this process, when the head 131 moves downward, a clearance is required for the connection part 120 to pass therethrough and the connection part 120 is formed along the opening part 220 formed on the side surface of the guide hole 210, The head 131 is not disturbed when it is moved downward.

In this case, the inner diameter of the guide hole 210 is designed to have a diameter similar to that of the head portion 131 of the head portion 130, thereby preventing the head portion 131 from being shaken during the drilling process. When the head 131 is inserted up to a certain depth in the guide hole 210, the head 131 is formed by the engaging jaw 132 formed on the top of the head 131, It can be prevented from being moved downward.

In other words, the implant handpiece 100 according to the present invention not only can form a hole at an accurate position due to the above-described structural characteristics, but also can always drill a hole having a predetermined depth. At this time, the depth of the hole formed may be determined by subtracting the height of the guide hole 210 from the height of the head portion 130 plus the length of the drill 140. [ At this time, when a plurality of connection portions 120 having head portions 130 having different heights are provided, holes can be formed by a required depth by adjusting the height value of the head portion 130.

Referring to FIG. 6, there is shown an example in which a hole is formed in the left mandible using the implant handpiece 100 according to the present invention.

As described above, the implant handpiece 100 according to the present invention is provided with the detachable connection portion 120, and the connection portion 120 suitable for the operation position and the position of the opening formed in the guide hole 210 is selectively It is possible to combine them.

For example, when a hole is to be formed in the left mandible, as shown in FIG. 2, the first connection portion 121 described in FIG. 2 may be coupled to the handle 110. In this case, the implant handpiece 100 can approach the guide hole 210 in a state in which the implant handpiece 100 is bent in the leftward direction and the downward direction along the longitudinal direction of the handle 110. At this time, it is preferable that the guide hole 210 is formed with an opening toward the direction in which the first connection part 121 approaches.

The head portion 130 can be inserted into a position guided by the guide hole 210 of the guide template 200 so as to form a hole at a position for placing the implant. That is, in the implant handpiece 100 according to the present invention, the head portion 130 can be directly inserted into the guide hole 210. For this purpose, the shape and diameter of the guide hole 210 correspond to the head portion 130 As shown in FIG.

The drill 140 coupled with the head 130 can enter the ditch and begin to form a hole as the head 130 moves down while contacting the inner wall of the guide hole 210. At this time, when the head part 130 moves downward by a certain depth, it is prevented from being further lowered by the engagement protrusion 132 formed on the upper part of the head part 130, .

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined in the appended claims. It will be possible.
