Abstract

The present invention relates to an apparatus for accurate guided placement of implants comprising a drill and guide bushing. More specifically, while the inner circumference of the guide bushing has a circular form, the outer circumference is formed in an oval shape. Thus, the apparatus prevents the guide bushing from rotating together with the drill during drilling. Also, the guide bushing can be easily mounted even if the implant site is placed at a narrow gap between teeth. A drill for drilling alveolar bone comprises a guide portion at the lower part of a drill shank so that the drill can be induced by tightly closing the circular inner circumference of the guide bushing. The guide portion is integrally formed with the drill or is coupled to a screw formed at the outer circumference of the drill shank in a pipe shape. The drilling depth is limited by inter-connection of a stopper with the sloped surface of a flat head formed at the upper surface of the guide portion. The stopper comprises a chamfer of the edge of the upper through-hole formed at the guide bushing.

As a stopper is formed, expensive equipment such as a numerical control (NC) machine can be used to form a stopper at an accurate position, which causes a high processing cost. In addition, by forming a chamfer along the edge of the protruding portion of the stopper, it is preferable to increase the convergence with the inclined portion of the lower edge of the guide part provided in the drill. Thus, the chamfer is formed on the inner circumferential surface thereof through the through hole of the guide bushing. Doing that is a bit cumbersome and reduces productivity.

Increasing the type of induction bushing means that the types of drills having induction parts corresponding to the inner circumferential surface diameter of the induction bushing should also be increased. Furthermore, the types and numbers of drills to be prepared are exponentially varied. Should increase. Accordingly, it is necessary to minimize the type of drill that can cope with various kinds of induction bushings.

There is an inefficient aspect that the life of the drill is determined by the wear state of the guide rather than In most cases, the drill blade is coated with an expensive coating material, while the induction bushing of the drill that comes into contact with the induction bushing and the large surface while rotating at high speed has no protection. However, it is not preferable to apply an expensive coating material to the induction part in that it increases the cost of the product. Therefore, it would be more desirable to solve this problem in connection with the minimization of the type of drill, the first of which needs improvement.

In order to precisely induce the drill having the induction part, it is preferable that the induction part is closely contacted with the inner circumferential surface of the induction bushing. The narrower the gap between and the guide bushing, the greater the moment that the guide bushing also rotates due to the rapid rotation of the drill. This moment acting on the induction bushing is a factor that hinders the rigidity of the induction bushing fixed to the stent. Therefore, in order to precisely implant the implant, it is necessary that the supporting integrity of the induction bushing is not impaired even by the moment caused by the rotating drill.

By varying the type of hollow cylindrical guide part, which is easy to process, it is possible to minimize the type of drill with a relatively high cost. Also, if the cutting part of the drill is in good condition, the life of the drill can be extended by simply replacing the guide part. As a result, such a new type of drill for drilling holes is considerably more effective than before.

In addition, a cylindrical guide portion 120 is provided on the lower outer circumferential surface of the shank portion 100, and the upper surface of the guide portion 120 is formed in the shape of a dish head 122 having an inclined surface 124. The outer diameter of the induction part 120 has a size corresponding to the diameter of the through hole 212 of the induction bushing 200 to be described later, in close contact with the outer circumferential surface of the induction part 120 and the inner surface of the through hole 212. As a result, the drilling direction of the drill 100 is induced. In addition, the drilling depth of the drill 100 is limited by the contact between the inclined surface 124 of the dish head 122 and the stopper 214 of the guide bushing 200.

Therefore, the inner diameter of the induction part 120 'is kept constant, so that various types of induction parts 120' different from only the outer diameter are prepared in advance, thereby actively responding to the induction bushing 200 having various diameters. .

When drilling, it is desirable that the guide portion 120 'is not easily loosened. In this case, in most cases, the cutting rotation direction of the drill 100 'is a right screw direction, and thus the threads formed in the male thread part 128' and the female thread part 126 'are formed as left threads.

Therefore, even when the guide parts 120 and 120 'of the drill are rotated at high speed while being guided along the through hole 212, the guide bushing 200 fixed to the stent has a cross section perpendicular to the drilling direction of the drills 100 and 100'. Since the shape is elliptical, it is possible to suppress the induction bushing 200 to rotate together with the rotation of the drills 100 and 100 '. Incidentally, such an elliptic cylinder shape has an advantage that the induction bushing 200 having a small size can be easily grasped by hand to facilitate its handling.
