Referring to fig. 4 to 13, the operation of using the bone drilling device of the present invention to drill a bone is illustrated, first, the bone drilling device a of the present invention is connected and positioned with the surgical tool B to form an integrated assembly, and the present invention is characterized in that the second base 51 of the lower fastening member 50 is a sheet with a suitable width, and the first arm 511 and the second arm 512 are configured in a long and short manner, so that the first arm 511 and the second arm 512 can be smoothly and quickly placed and positioned in the drill 73 and cross over the two sides of the bottom end of the drill 73 by obliquely taking the integrated assembly, so that the nut 33 can synchronously drive the upper fastening member 30 to move downwards and clamp and position the first arm 511 and the second arm 512 when the nut 33 is screwed with the second fastening portion 52 (stud) of the lower fastening member 50 by the surgical tool B, meanwhile, the upper packing member 30 can cover the drill hole 73, and the operation is very convenient and fast.

As shown in FIG. 14, the bone drilling and capping device A of the present invention is first connected to the surgical tool B to form an integral assembly, so that when the bone drilling and capping device A and the surgical tool B are simultaneously implanted into the position of the bore 73 of the skull 70, the second base 51 of the fastening member 50 of the present invention has the first arm 511 and the second arm 512 arranged in a long and short manner, which can respectively cross over the top of the skull 72 and the bottom of the skull 70, and then the surgical tool B drives the upper fastening member 30 to move downwards, so that the nut 33 is screwed with the second coupling portion 52 (stud) to move downwards, which can drive the first arm 511 and the second arm 512 which fasten the upper fastening member 30 and the lower fastening member to generate a clamping force, thereby effectively and stably clamping the skull 72 on the skull 70, and the operation is very convenient and fast.

When the invention is used for fixing the skull and has the function of adding a drainage tube, as shown in fig. 3 and 4, the internal thread hole 53 of the second combining part 52 (stud) continuously penetrates to the second base part 51 to form a through hole 531 for inserting the drainage tube (not shown) for drainage; or as shown in fig. 15, only a petal 312 is cut into the second base part 51 of the upper fastening member 30 at the position staggered from the lower fastening member 50 to form a gap 313, so that the drainage tube 80 can be inserted; or as shown in FIG. 16, the plurality of slots 311 of the upper packing member 30 can be formed into a key hole shape having an opening 314 smaller than the diameter of the drainage tube 80 and a limiting hole 315 larger than the diameter of the drainage tube 80 for the drainage tube 80 to be clamped and limited; therefore, the second base portion 511 of the lower fastening member 50 of the present invention is formed into a sheet with a suitable width, so that the present invention can be applied to any structure shown in fig. 15 and 16, and is not subject to any structural change at all, thereby having a wider application range.

After the bone drilling and covering device A is suitable for covering the drill hole 73 of the bone at any position or fixing the skull 72, the surgical tool B can be quickly taken out of the bone drilling and covering device A only by moving the outer sleeve 60 of the surgical tool B upwards and reversely rotating the surgical tool B in the same way as the background technology; on the contrary, if the bone drilling and capping device A or the skull 72 is to be removed, the device 10 can be removed from the skull (bone) 70 by only the reverse operation, and the present invention is very quick and convenient in both implantation and removal operations.

Compared with other prior art, the bone drilling and covering device A provided by the invention has the following advantages:

1. the lower fastening member 50 of the present invention is configured by the first arm 511 and the second arm 512, and the width of the lower fastening member is smaller than the diameter of the bore 73, so that the first arm 511 and the second arm 512 can be easily inserted into the bottom end of the bore 73 by inserting the lower fastening member 50 obliquely toward the bore 73, the bore 73 of any bone can be covered, the operation is very quick and simple, the bore 73 can be maintained at the minimum diameter, and the damage to the bone structure can be minimized.

2. When the skull drill is used for fixing the skull, the first arm 511 and the second arm 512 can form long and short configurations and respectively cross the top-pulling skull 72 and the skull 70 to be tightly clamped, so that the bone drilling or any bone drilling for fixing the skull can be effectively applicable, and the universal application range and the efficiency are effectively improved.

3. When the drainage tube 80 is required to be additionally arranged for fixing the skull, the second base part 51 is a sheet body with proper width and long and short configuration, so that any additional structure is not required to be changed, only the upper forcing piece 30 is required to be changed, and the effect of effectively saving the manufacturing cost by omitting the change of the lower forcing piece 52 is achieved.

4. The invention not only has the excellent effect progress, but also maintains various effects of the background technology, and the functional benefit is improved and advanced compared with the invention.

In addition to the above-mentioned combination method, as shown in fig. 17, the collar and the nut of the first combination portion 32A are only simply engaged, and the second combination portion 52A is another combination embodiment of the stud; or as shown in fig. 18, the first combining portion 32B and the second combining portion 52B respectively form a combining manner of an inner screw hole and a stud; or as shown in fig. 19 and 20, in the first embodiment of the combination with a binding band, the first combination portion 32C forms a buckle hole with an elastic buckle portion 325 inside, and the second combination portion 52C forms a long strip-shaped sheet-shaped band with a proper length, and at least one side of the band is provided with a ratchet-shaped buckling portion 522 for buckling the buckle portion 325; or as shown in fig. 21, in the second embodiment of the combination with the binding band, the first combination portion 32D forms a fastening hole with a big top and a small bottom, and the second combination portion 52D is a slender rod-shaped band, and a plurality of convex cone-shaped engaging portions 522 capable of fastening the conical fastening hole are protruded on the slender rod at intervals; after the belt member is inserted into the fastening hole, a surgical tool C is used to drive the upper tightening member 30 to move toward the tightening member 50 for tightening and fixing the hole.

The device of the invention can really achieve the aim that the drill hole of any part of the skeleton can be suitable for covering knots, and can also be relatively suitable for fixing the skull, thereby achieving the purposes of being suitable for both drilling holes and fixing the skull, having simple and rapid operation, being tightly clamped and firm, and effectively achieving the practicability of improving the general use range and efficiency.

The foregoing description is intended to be illustrative rather than limiting, and it will be appreciated by those skilled in the art that many modifications, variations or equivalents may be made without departing from the spirit and scope of the invention as defined in the appended claims.
