Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a screw hole punching device,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a piercing mechanism for piercing a screw hole in a shielding film for use in medical use.

Generally, absorbable or nonabsorbable tea membranes are used in osteoinduction regeneration of orthopedics, neurosurgery, and dentistry.

In the case of a dentist, for example, the alveolar bone induction regeneration procedure, in which the bone is implanted and regenerated in the damaged alveolar bone region due to tooth damage during the dental implant, is performed.

Such an alveolar bone induction regeneration procedure is a process in which a nonabsorbing shielding film such as an absorbent shielding film or a titanium mesh plate is placed on a lost alveolar bone and fixed with a screw or the like.

At this time, the operator forms a screw hole into which the screw is inserted on the shielding film for guiding and regenerating the bone, and then the shielding film for guiding and regenerating the bone is screwed onto the alveolar bone.

At this time, since the shielding film for bone induction and regeneration should be fixed on the alveolar bone, the shielding film should have a curved shape so that the curved shape of the shielding film should not be deformed in the process of forming the screw hole. However, The operator is holding the shielding film for guiding and regenerating the bone with one hand and holding the handpiece rotating at a high speed with the other hand while pushing the shielding film for guiding and regenerating the bone with the handpiece, There is a problem that it is difficult to fix the shape on the alveolar bone.

In addition, in order to cool the heat generated during drilling using the handpiece at high speed rotation, water comes out from the handpiece.

Further, when the handpiece rotating at a high speed drills the shielding film to form a screw hole in the shielding film, there is a problem that the microparticles separated from the shielding membrane are spilled around and cause injury to the practitioner and the surrounding people.

In addition, since the shielding film is formed in one direction by the de-ring through the handpiece to form a screw hole, the screw hole rim protrudes in one direction of the shielding film for guiding and regenerating the rib, and the protruding portion must be polished by a grinder or the like .

In addition, the shielding film is very soft even when forming the screw hole of the other absorbent and nonabsorbing shielding film. Therefore, when the hole is formed with a general scalpel or surgical scissors, it tears very badly and the hole size becomes very irregular. In the alveolar bone induction regeneration for the implant, .

It is an object of the present invention to provide a screw hole piercing mechanism for a shielding film for guiding and regenerating a bone, which is capable of easily forming a screw hole in a shielding film without deforming the shape of a shielding film .

In order to achieve the above object, the screw hole piercing mechanism of the shielding film for guiding and regenerating bone according to the present invention is a piercing mechanism for forming a screw hole in a shielding film for guiding and regenerating bone, And the first handle and the second handle are formed at the rear ends of the first handle and the second handle, respectively. The front end of the first handle and the handle of the first handle and the second handle are spaced apart from each other, A first rotating bar and a second rotating bar on which two operating parts are formed; A die body detachably coupled to an upper portion of the first actuating portion and formed in a dome shape facing upward and having a hollow body with a via space portion formed therein and a punch hole formed at a center of the die body to be connected to the space portion; And a punch body which is detachably coupled to a lower portion of the second operation portion and is formed as a dome-shaped downward portion; a punch body protruding downward from a center of the punch body, the punch body being formed at a position corresponding to the punch hole, And a punch part configured to be inserted into the hole, wherein a gap between the first actuating part and the second actuating part is changed according to an operation of the first knob part and the second knob part by the user And the screw hole is formed in the shielding film located between the die portion and the punch portion by inserting the punch projection into the punch hole.

Wherein the die portion and the punch portion are formed in a plurality of sizes with respect to the punch hole and the punch projection so that the die portion having the specific dimension among the plurality of die portions and the punch portion and the punch portion And the size of the screw hole formed in the shielding film can be adjusted by attaching the screw hole to the second actuating part.

Wherein the first handle and the second handle are provided so as to connect the first handle and the second handle, and when the external force is removed in a state where the first handle and the second handle are close to each other by the external force of the user, And an elastic member that provides an elastic force to return the member to the home position.

The elastic member may be formed of a torsion spring.

And a stopper provided on any one of the first handle and the second handle to limit the minimum interval of the first actuating part and the second actuating part closest to each other to a predetermined length have.

First coupling means for detachably coupling the die portion to the first actuating portion; And

And second coupling means detachably coupling the punch portion to the second operation portion.
