Bone Drill Cover Device

Abstract

The invention relates to a bone-drilling hole covering device. The bone-drilling hole covering device comprises at least an upper pressing member and a lower pressing member, wherein the upper pressing member is provided with a first base part and a first joint part, the lower pressing member at least includes a second base part and a second joint part which is combined with the first joint part,and the second base part consists of at least a first arm and at least a second arm; and the total length which is formed by the first arm and the second arm is larger than the diameter of a drill hole, and the length of the first arm is controlled to be longer than the length of the second arm. Accordingly, short-and-long configuration can be formed by the first arm and the second arm, the firstarm and the second arm can be inserted obliquely, and then be positioned at the bottom end of the drill hole, and drill holes at any parts of a bone can be attained, covered and jointed, the operationis fast and easy; and the minimum hole diameter of the drill hole can be maintained so that damage to the bone structure can be minimized, and the first arm and the second arm can be used for crossing cranium and skull separately so as to achieve jacking and drawing when the bone-drilling hole covering device is used for fixing the cranium, so that the general use range and efficiency are improved effectively.

Description

technical field [0001] The invention relates to a bone drilling cover device capable of improving the scope of use, sharing and improving performance. Background technique [0002] China Taiwan Region Announcement I609670 "Cranium Fixation Device and Its Surgical Tools" Invention Patent Prior Case, which is an invention developed by the applicant for a utility model and approved by the bureau; the cranium fixation device includes at least one pressing part and one activity The buckle assembly can be configured with a certain distance from the outer surface of the skull when the entire movable buckle assembly is positioned on the outer sleeve, so as to facilitate the implantation and reset of the skull. [0003] Although the above-mentioned fixing device can achieve the convenience and progress in clinical operation of fixing the cranium; however, the lower pressing part is a circular structure, and its outer diameter is larger than the inner diameter of the drill hole, so it...

Problems solved by technology

The lower tightness of the above-mentioned invention can't be inserted by the single drill hole, and it can't be applied to the single drill hole of the bone to cover the knot. Tissues are easy to fill and affect normal bone hyperplasia. These drill holes are easily damaged when touched by external forces without the protection of the cap. This is a problem that the medical field wants to solve.
