New description: • [New technical field] The creation department is related to a self-tapping bone. For orthopedics, dental or cosmetic medicine, etc. = improved structure, especially a special type of screw joint using the bone needle. Designed to make it = human implantable fixation material. When it has the advantage of easy screwing and good positioning, it is screwed into the human skeleton with a hand tool. [Prior Art] Μ . In the field of dental orthodontics, problems such as missing needles are solved; for example, the shape of the bridge, the shape of the 2, the position, the arrangement, or the like. Please also refer to the first and second figures to complete, fill the teeth or correct the wrong bite. The bones are used to make the bones 2Q in the above surgical technique, through the elastic element 22 and the bone nail 1〇 connect Z let Both ends of the straightening wire 21 are respectively 21, and the purpose of the tooth is reached. The elastic member 22 pulls the continuous wire portion 12, and the platform u includes a rectangular kiln 0 including a platform η and a screw-spinning operation, and the rectangular cylindrical surface U1 is provided for the sleeving tool to engage the engaging portion 113. The poor perforation 112 or the hole (1), the platform lljL is convexly fixed. The thread (4) is attached to the upper thread of the screw = 13 series for the elastic element (10) to be connected for screwing and positioning for performing the locking. The thread has a tip end with a tapered end 121. The bracket 23 and the correcting wire 21 are attached to the tooth 2. When the bone nail 10 is used, the predetermined position is first placed on the elastic member 4, and the bone nail 10 is locked to the bone. On the positive steel wire 21, the elastic member 22 is provided by the end of the 颚 (4) fixed to the bone nail _ bridge correction copper wire 21 to provide the elastic member 22 and the only check, (4) the above _ can force = ^ The tip of the thread of the tooth of the tooth (4) is a male-shaped tapered shape. The locking force of the M428751 is insufficient. A nail with a small diameter is likely to cause breakage or collapse. Furthermore, the nail 10 is also insufficiently locked in the initial screwing, so that the locking angle may cause an offset skew. This situation may cause an increase in the sacral region of the humerus 2 time. [New content] The purpose of this case is to improve the problem of poor bone screwing ability and insufficient positioning ability, which may cause problems such as difficulty in screwing the nails, increase in the area of the destruction of the humerus, and so on. Improved positioning of the bone nails. To this end, the present invention includes a platform portion and a screwing portion for the spin-lock operation of the hand tool and the fixing of the elastic member. The main design is that the screwing portion is formed into a first screwing region and a second screwing region, and the first screwing region and the second screwing region are formed on the screw whose diameter is gradually increased from small to large. Thread, the end of the second screwing zone is a cutting end, and the cutting end has at least one edge. In this way, the bone nail can be screwed into the tibia, and the elastic element of the two ends of the straightening wire can be used to pull the shank to achieve the purpose of aligning the teeth. The bone nail has the advantages of easy screwing and good positioning. [Embodiment] The technical content, features and effects of the present invention will be clearly described in the following detailed description of the preferred embodiments of the reference drawings. In addition, the present invention is specifically described before it is described in detail, and the drawings are used to explain the basic structure of the present invention in a schematic manner. Therefore, only the elements related to the present case may be displayed in the drawings, and the structural shapes are displayed. , size, ratio, or the number of components 4 M428751, etc., is a selective design, which is described first. 3 and 4 are a perspective view and a plan view of a preferred embodiment of the present invention. The bone nail of the present invention is divided into two parts, wherein one end is defined as the flat end portion 30 of the operating end, and the other end is defined as the screwing portion 40 of the locking end, and the platform portion 3〇 is integrally extended with the screwing portion 40. Set up. The platform portion 30 includes a rectangular cylindrical surface 31 for arranging a hand tool for performing a twisting operation. The rectangular surface 31 is provided with a through hole 32. The top end of the platform portion 31 is convexly provided with a fastening post 33'. The fastening post 33 is for the elastic element to be coupled to the holder. The screwing portion 40 is further divided into a first screwing portion 41 and at least one second screwing portion 42. The first screwing portion 41 and the second screwing portion 42 both form a screw 44 on the screw 43, and the thread 44 The lower surface is about 30 degrees, and the upper surface is about 15 degrees. This one thread shape can increase the torsion and bearing capacity' and the thread can be implanted deeper every revolution, making it faster. Implanted bone. In addition, the projection of the second screwing region 42 is not centrally symmetric. Further, the middle two of the screw α is not the center line of the thread 44, and this design can make the underlying thread 4 4 After screwing into the shank line, the subsequent thread 44 can penetrate the bone in a lesser amount of progressively, making it easier and less disruptive to the bone. The second screwing portion 42 has a cutting edge 421 on the cutting end 421. The cutting portion 421 has a blade portion 422. The top end is a two-cut end point, and the angle of the edge portion 422 is between 110 degrees and 115 degrees, and the length of the * tip is 112 · 93 degrees. Since the top end of the blade portion 422 is a sharp point, The angle of the car is 112.93 degrees. When the knife part 422 is drilled in the initial stage, it can have good introduction cutting effect and self-tapping ability, and it can prevent the planting from being skewed and implanted. The reversal occurs at the same time, and can have a more (4) positioning effect ^ 5 M428751. It makes it easier and smoother at the beginning of the twist lock. In addition, the angle between the screw circle of the second screwing region 42 and the center line is the twist, and the diameter of the screw 43' of the second screwing portion 42 is gradually increased from small to large. The progressive design of the body can reduce the reaction force of the twist lock in the initial stage of the twist lock. At the same time, it can reduce the hard friction between the bone and reduce the risk of bone necrosis. Of course, the progressive design of the shaft also helps. The ease of screwing in. According to the structure of the nail embodiment of the present invention, the bone nail can be twisted into the shank (or other bone) by using the hand tool, and the elastic member can be connected by the two ends of the straightening wire. The elastic member is further coupled to the through hole 32 or the fastening post 33 of the platform portion 30 of the nail, and the elastic wire is used to pull the I wire to achieve the purpose of correcting the tooth. In particular, by the structural design of the screwing portion 4 of the present case, the upper and lower spiral surfaces of the thread 44 on the screw 43 are respectively designed to be 15 degrees and the degree of force can be increased by using the thread shape. The diameter of the screw 43 of the second screwing region 42 is gradually increased from small to large, except that the reaction force of the twist lock can be reduced at the initial stage of the twist lock, and the hard friction with the bone can be reduced, thereby reducing the bone. The probability of necrosis; in particular, the cutting portion 421 at the end of the second screwing region 42 has a knife portion 422 which can improve the self-tapping ability, and can reduce the breakage of the bone, and prevent the skew and implantation during the rotation. The subsequent reversal occurs, and at the same time, it has a better positioning effect, making it easier and smoother at the beginning of the twist lock.
