New description: [New technical field] Shape, age, society, structure change [Prior technology] Bone fixation system - lion-like steel nails • Used to penetrate bones (such as vertebrae), fixed bone The location of the network. The first garment lc # _ is derived from the prior art, and its structure includes a head portion η, a receiving portion 12, and a screw 13. The head u has external threads which are engageable with the internal threads of the receiving portion 12 to be screwed to each other. As can be seen from the figure, there is a space 14 in the receiving section = which allows for the insertion of a stick (not shown). By the rotation of the head 11 and the accommodating portion 12, the direction of the arrow 15 can be pressed to fix the bone fixing device and the rod to each other. At the same time, the position of the bone can be fixed because the screw 13 penetrates into the bone. The screw 13 can be fixed (mono_axiai) or, as shown in Figure lc, can be controlled to rotate (referred to as poly-axial). The screw 13 of the multi-shaft bone fixation device has a spherical axis 131 embedded in the bottom of the accommodating portion 12 to rotate the screw 13 with respect to the accommodating portion 12. A disadvantage of the prior art described above is that the accommodating portion 12 is subjected to the outwardly expanding force due to the pressing of the lock from the direction of the arrow 15. Under a long period of time, the accommodating portion 12 may expand and deform outward, causing the rod to loosen. In view of this, the prior art proposes another bone fixation device, as shown in Figures 2A-2B. In the bone fixing device, in addition to the head portion 21, the accommodating portion 22, and the screw 23, an outer nut 27 is additionally provided. The outer nut 27 has internal threads, and the M327224 portion 22 has external threads that cooperate to lock each other. Use Japanese, two. After locking the rod, the outer nut 27 is screwed to the accommodating portion J, and the housing portion 22 is expanded and deformed outward. In order to enter, Lian Ji Nen, the singer, and the singer A&te need to take the _ action, increase the operation time and risk, so it is surgery; In addition, the outer nut 27 increases the west of the bone and affects it in the human body. ^The size of the device, it is necessary to improve the shortcomings of the above two prior art. [New content] = In the above description, the purpose of this creation is to propose better. Gu Yuu, bribes the above-mentioned structural deformation problems, and does not do the difficulty of doing things. According to the above purpose, this hand is proposed. The two kinds of bones are used to pierce the bone path... The inner secret space is for storage-external rods; the outer ring sleeve is inserted into the outer periphery of the storage part to prevent The accommodating portion is deformed and deformed, and a head portion is lockable to the accommodating portion, and the outer ring sleeve can be fixed by locking. The bone lateral setting device of the present invention can be formulated or multi-axial. In the preferred embodiment, the outer circumference of the receiving portion is recessed corresponding to the outer ring sleeve, so that the outer diameter of the outer ring sleeve is not increased after the receiving portion is fitted. The other side implements a crane towel, and the outer county τ side has a gap corresponding to the shape of the outer rod. The specific embodiments are described in detail to make it easier to understand the purpose, skill, meaning, and effect of the creation. M327224 [Embodiment] The object is fixed by a 'lock-by-lock action' to fix both the rod and the outer ring sleeve for preventing deformation. The above concepts, there are many # First please refer to __ _, pure description. In the embodiment, the bone bones are 0 &, the brothers apply, the head and the outer head 31, the accommodating portion 32, and the screw

The Qing 31 has an extension, 3 inches, which can cooperate with the top of the outer ring sleeve 37, when the head 31 and the storage unit are mutually When locked, the extended outer edge 311 also abuts against the top 0 of the outer ring sleeve 37. Further, according to a preferred embodiment of the present invention, the outer portion of the receiving portion % should be designed to have a partially concave shape. The recess corresponds to the thickness ' of the outer ring sleeve 37' such that after the set of tilting wires are combined, the outer diameter is not increased by the outer sleeve. Further, in order to accommodate the accommodating rod (not shown), below the outer ring sleeve 37 (left side of the drawing), a corresponding notch can be provided as shown. Referring again to Figures 4A-4C, which is a second embodiment of the present invention, in the present embodiment, the bone fixation device includes a head portion 41, a receiving portion 42, a screw 43, and an outer ring sleeve 47. The bone fixation device of this embodiment may be of a fixed type or a multi-axis type, and the figure is illustrated by a multi-axis type, so that the screw 43 has a spherical shaft M327224 core 431. The difference between this embodiment and the previous embodiment is that the head 41 does not abut against the top of the outer ring sleeve 47. As shown in the figure, the inner portion of the outer ring sleeve 47 (the bottom portion of the outer ring sleeve 47, but may be at other positions) has an inner edge 471 extending inwardly; when the M1 and the receiving portion 42 are locked with each other, the head portion 41 At the same time, the inner edge 47 of the outer ring sleeve 47 is not in a complete circumferential shape, and the space opening of the receiving portion 42 is included in order to facilitate the inclusion of the space opening. In the above two embodiments, in order to facilitate the rotation of the heads 31 and 4, the top surface of the head portion may be provided with a groove corresponding to the rotating tool, such as a hexagonal groove, or a cross screw hole, etc., not shown . The above description has been made with respect to the preferred embodiment, but the above description is only for the purpose of understanding the singularity of the syllabus, and is not intended to define the mushy side range. Those who are familiar with the technology can immediately think about various equivalent changes when they are within the concept. For example, the complexity, length, etc. of the parts of the bone flipper are not limited to the illustration; in addition to the j parts shown, the scales may also be added (for example, the control 绮 radial rotation Lu 6, parts); .
