New description: [New technical field] This is a kind of improved bone fixation structure for fixing the position of multiple vertebrae and providing a skeleton fixation structure.幻幻筏力 [Prior Art] When the human spine fractures or dissociates (four), the reduction of the spine can be reduced, and the spinal cord is compressed; while the conventional spine reduction system is on the right side of the bones of the human spine joint or When fishing in the vertebrae 2 is not in the straight line, the method of passing the f is nothing more than bending the spinal rod, and using the clip member to clamp and fix the j-connected #, but this means will derive many Missing, for example: the basin == position of the central film can not be clamped, and the film can only adjust the angle of the moon nail in one direction, but can not be adjusted arbitrarily at various angles, and the other is a little farther away from the connecting rod. The fixing of the connecting part of the connecting rod does not even have the problem of being unusable; in addition, the conventional spine multiplex can only adjust the fixed angle of the nail in one direction or two directions, and cannot reach the ΐ:: angle Adjustable purpose' However, through the experience of treatment, it is shown that if the field vertebra complex (4) is unable to determine the position of the spine f-segment, the effect of the treatment will be seriously impaired; in addition, the structure of the conventional spinal reduction system is complicated, and the failure rate High, there is a need for improvement. [New content] This creation provides a bone fixation mechanism that facilitates adjustment of a fixed orientation, which allows the spinal rod and the nail to be accurately positioned and firmly joined to effectively fix the bone to be treated. Heart M409817 In order to achieve the above (4), the improved bone fixation structure of the present invention is a bone nail, a screw cap and a fixed seat, and one or a plurality of connecting rods together, and the 'hunting is divided by the materials. On the vertebrae, and make the screw-on cap to connect the bone nail to the end of the fixed seat, and the other end of the day = the other end of the solid seat, so that between the bone needle and the connecting rod Accurately and firmly integrated in the 'from here' to ensure the correct position between the respective vertebrae, and provide a moderate support; where:, the squat-end has a horizontal sleeve hole, and in the horizontal sleeve ^ & radial 1 ^ screw 'the fixed contact end - the end has a vertical upwardly downward tapered hole, and the lower end of the tapered hole is provided with a concave spherical mask j 'in the spherical cover The tapered hole is slotted to increase the joint stability of the concave spherical surface, and the upper end 6 has a spherical lip that protrudes upward. The bone nail has a slightly screw-like configuration, and the nail head has a spherical surface that is convex upward, and the surface can be sleeved and assembled in the fixed seat (four) mask. Therefore, the setting can be made at any angle. a first knob is disposed on the outer circumference of the spherical surface and a screw is protruded from the surface of the ball, and a second knob portion is driven by the first and second knob portions to drive the bone screw into the bone Or adjusting the setting angle of the nail; further, the bone nail is provided with an external thread on the body, and the lower end portion of the body is tapered and provided with a slit, and the tapered lower end portion and the threaded slit are designed to The bone nail body is easy to be screwed into the bone. The screw cap has a hexagonal knob portion, and a hole through the hole is arranged at the center portion to be screwed on the stud above the bone nail. The bottom surface of the cap is provided with a concave spherical surface. The concave spherical sleeve is combined with the spherical lip of the fixing seat, so that the setting can be tightly fitted at any angle M409817 degree. The connecting rod can be arranged in a linear or curved configuration according to the requirements of the installation site, and is provided with a plurality of rotations (four) on the rod body for applying force to adjust the setting angle or position of the connecting rod; preferably, The connecting rod is made of a composite material having elasticity, strength and corrosion resistance or a metal material, wherein the composite material is selected from polyether ether ketone (PEEK) or carbon. Plain fiber, etc., and the metal material is selected from titanium alloy, combined gold, non-recorded steel, etc., but the scope of implementation is not limited to the above materials, and various types are suitable for planting in the human body and have good machinery. Both strength and chemical resistant alloy materials or biocompatible polymer compatible materials are suitable. This will be explained below with respect to other objects, advantages and salient features of the present invention, which are familiar to those skilled in the art after reading the description in the text. [Embodiment] As shown in the first and second figures, the component assembly aspect of the present embodiment is provided; the bone nail 1 is provided with an outer 12 on the body, and the lower end of the body is tapered and provided with a slit 13 The f nail body can be easily implanted in the body of the nail, and the end string S of the JU seat 2 is locked in the nail head portion of the nail nail by the screw cap 3, The connecting rod 4 is pivotally connected to the other horizontal end sleeve hole 21 of the fixing base 2, and is locked and fixed by a radial pressing screw 22 disposed on the horizontal sleeve hole. Please refer to the cross-sectional view of the component combination of the present embodiment shown in the third figure; the ball head portion 14 of the bone nail 1 has an upwardly convex spherical surface 14 and the outer peripheral edge of the spherical surface is provided with a knob portion 15 The ball has a 5 M409817 stud 16 and a knob portion 17 extending upwardly; and the fixing base 2 disposed at the nail head portion of the nail has a vertically disposed tapered hole 23, and the lower end of the tapered hole is provided with a concave surface. The spherical mask 檐 24 is further provided with a slit 25 (such as the fourth figure) for improving the joint stability on the inner circumference of the tapered hole of the spherical mask ' portion, and an upwardly protruding spherical lip is provided at the upper end of the tapered hole. The screw cap 3 that is locked to the nail head portion of the nail has a hexagonal knob portion 31 and a through hole 32 is provided at a central portion. In particular, the bottom surface of the sleeve cap is provided with a concave surface. The spherical surface 33; according to the embodiment, the tapered hole 23 of the solid seat is sleeved on the nail head portion of the bone nail, so that the concave spherical mask 24 at the lower end of the tapered hole and the upper convex spherical surface 14 of the bone nail The socket set _ is combined, and the fixing seat 2 and the bone nail 1 can be at any set angle by the socket combination of the concave and convex spherical surfaces. The screw hole 32 of the screw cap is screwed onto the stud 16 of the bone nail, and the concave spherical surface 33 of the bottom surface of the screw cap is sleeved and assembled to the fixing seat. The upper convex ball, <=edge 26, also by the concave and convex spherical sleeve combination, the solid seat 2 and the screw cap 3 can be tightly fitted at any set angle, as described above. The illustrated combined structure, before the screw cap 3 is not tightened, the screw cap 3, the fixing base 2 and the bone nail are sleeved and combined by a concave and a convex spherical surface, so The components can be placed at various angles of ', and 5 (as shown in the fifth figure), that is, the direction and position of the bone nail into the vertebrae can be adjusted as appropriate, but when the screw cap 3 After tightening, the screw cap 3, the fixing base 2 and the bone nail can be tightly locked together, so that the entire bone fixing structure and the spinal joint can be accurately clamped and firmly combined. Together to achieve effective therapeutic goals. It can be understood that the related components of the above-mentioned bone fixation structure are placed in the human body, so that the selected materials are required to have chemical resistance and biocompatibility in addition to the required mechanical properties.
