Abstract
A bone drilling cover fixing device includes an upper fastening member and a lower fastening member. The upper fastening member includes a first base portion and a first coupling portion. The first coupling portion protrudes from an underside of the first base portion and can be inserted into a drilled hole. The lower fastening member includes a second base portion and a second coupling portion. The second base portion includes at least one first arm and at least one second arm. The first arm has a length equal to that of the second arm. The length of the first arm and the length of the second arm are greater than a radius of the drilled hole. When in use, the first and second arms are inserted in an oblique manner into the drilled hole to be positioned at two ends of an underside of the drilled hole.
Claims9
A bone drilling cover fixing device, comprising:
- an upper fastening member, including a first base portion and a first coupling portion, the first coupling portion being disposed on the first base portion and protruding from an underside of the first base portion, the first coupling portion having a diameter less than a diameter of a drilled hole;
- and
- a lower fastening member, including a second base portion and a second coupling portion, the second base portion including at least one first arm and at least one second arm, the first arm having a length equal to that of the second arm, the second coupling portion being disposed on the second base portion, each of the length of the first arm and the length of the second arm being greater than a radius of the drilled hole;
- wherein, when in use, the first arm and the second arm are inserted in an oblique manner into the drilled hole to be positioned at two ends of an underside of the drilled hole, the second coupling portion is coupled to the first coupling portion, and a movement caused by a clearance between the first coupling portion and the drilled hole is not sufficient to disengage any one of the first arm and the second arm from the two ends of the underside of the drilled hole;
- wherein the second base portion is in a platy shape and has a width less than the diameter of the drilled hole.
