Description of the Invention: [Technical Field] The present invention relates to a device for implanting a spinal pedicle to a spinal pedicle. [Previous technique] The state-fixed spinal rod device, in particular, the position, the plurality of nail groups themselves are movable, the dynamic fixation, the non-fusion state, the traditional spinal injury, if the pedicle screw and the connecting rod are fixed, It is a joint of - titanium alloy or stainless steel, combined with a plurality of implanted spine = spine nails in the joint, and forcibly connecting the fixed vertebrae that need to be fixed in a hard-to-hard manner. However, such a hard and hard way to forcibly fix, in addition to failing to provide appropriate stress relief, can not cause micro-motion of the damaged vertebrae (4), to accelerate the proliferation of bone to help stabilize the damaged part, so that patients can stay in bed for a long time or With the support of the back frame, it is impossible to properly restore the original function of the spine as quickly as possible. If you only use the I-line type connecting rod to connect the bones (4), there are two main problems. The H-th line-type connecting rod is too rigid, so the traditional Chinese metal or stainless steel straight-shaped connecting rod is no different. If the cable type link is too soft, it does not provide proper support and the cable is easily deformed. Moreover, if a support tube is jacketed on the cable, there is a loss of flexibility, flexibility or curvature of the cable, which is no different from the use of a conventional link. Therefore, how to effectively solve the above-mentioned hard fixing, stress elimination, the connecting rod over the 200920307 hard, cable connecting rod is too soft and so on to effectively solve the above-mentioned problem of the vertebral rod device. The problem is changed from the design of the pedicle screw to the design, and there is a dynamic fixed ridge in this case.

The relative position defined in the present invention, 4I is as above, below, side, etc., and the hand is attached to the body of the dynamic fixed spinal rod assembly, and 5 refers to the user direction as the upper side, and vice versa. It is a side surface with respect to the periphery of the upper and lower ends. [Embodiment] In order to further explain the present invention, the embodiment is as follows: "Specific Example In conjunction with the drawings, the dynamic fixed spinal rod device 1A includes a nail set 20 and a connecting rod 30. The spine group 2 further includes a nail member 21 and a screw member 22, 8 200920307. The receiving member 2 1 is provided with a u-shaped groove 2 1 2, and the screw member 22 can be accommodated. And the connecting rod 30' can be first placed in the u-shaped groove 212, and then the male-inflicted screw 22 is screwed tightly and fixedly attached to the nail member 21. The two sides of the u-shaped groove of the 2-11 2 1 3 in the surrounding wall and 2, 2 and 2 in the bottom of the groove are all recessed with a 'crossing' and a flexible elastic body 4 (without elastic form). After being inserted into the squat groove 2 j 2 , the elastic member and the nail member 21 can be disposed between the elastic member and the fastening member 30 when the two sides and the bottom surface are in contact with each other. 40' and the screw 22 is screwed into the 'the elastic body 40 can make the connecting rod' and can be used as a dynamic fixed joint in the ridge 2 in the dynamic fixed spinal rod 1Q, wherein the elastic body can be an arc-shaped elastic piece 41 in a step, and the curved elastic piece is in surface contact with each other to form an elliptical elastic body, and the two are like the connecting rod 30, and are subjected to compression deformation. When the elastic force (four) material 21 and the material rod 3Q are connected to each other, or the elastic body step can be a ring-shaped elastic crystal, and the elastic end 2 contacts the nail receiving end 211 and the joint respectively. The rod 3〇: the joint balance. The Mi force maintains the nail η and the knot rod 30 and the elastic body may further be) or other different forms; the sponge, the elastic material), the plastic elastomer 43 and the plastic elastomer 43 (The cylindrical shape, the ball TPU, the cymbal, or other different plastics are in contact with the nail receiving end 211 200920307 and the connecting rod 3 〇, and when the compression is deformed, the elastic force is also provided to maintain the nail member 2 1 and the connecting rod 3 〇 The plastic elastomer is a hollow plastic elastomer 44 which, when compressed, has a hollow space 44 1 for deformation to provide elasticity. In Fig. 3, the other dynamic fixed spinal rod device comprises a spinal nail Group 60' contains one of the movable sleeves 6 1 and - screw 62, and a washer 63 and a screw 64, the u-shaped groove 611 of the receiving seat 61, the screw 62 and the washer 63 are placed, and the screw 64 is screwed into the joint; And a coupling rod 30 which is also identical to the previous embodiment, can be inserted into the u-shaped groove ... and is fastened by the screw 64 to fix the washer μ and the receiving seat 61. In Fig. 4a, the screw 62 It is a hemispherical head shaped 621 screw that does not directly contact and compress the hemispherical head end 621 of the screw, thus providing moderate mobility. When the screw member 64 is tightly fixed to the receiving seat, the connecting rod 30 and the washer 63, the ring 63, the receiving seat μ and the hemispherical end 62 of the screw 62 still have a space as a movable connection. . And an arc-shaped accommodating space 612 (to fit the outer circumference of the washer 63) is recessed on both sides of the wall of the U-shaped groove 611 of the receiving seat, and the washer 03 (both ends 631) can be accommodated The arcuate space 612 is again 乂, τ, and when the screw 64 presses the connecting rod 30 and the washer 63, the 誃 washer 63 (both ends 631) is engaged in the arcuate space 612, and The combination with the socket 61 is indirectly forced. In Figure 4b, in the two compartments 70 of the washer 63, the receiving seat 61 and the screw hemispherical head 10 200920307 shaped end 6 2 1 , the step can be loaded - the stable connection between the components No body 71, so that the elastomer 71 can be a soft elastomer of hollow or non-hollow plastic, a stable joint of soil or non-J 1 into the β-space 70, and a soft elastomer of η material , σ and the plastic, etc., can be placed into a step - sponge block, plastic, ΡΕ placed in the two 70 to provide flexibility, to maintain the gasket 63, to undertake the temple ± 亥 亥 螺 64 64 64, elastomer. "1. Connecting rod 3. In the case of the stable connection between the screw Q and the screw Q, the two types of dynamic fixed spinal rods 10 can be used in a single form, and the sacral vertebral body 8 〇, 81 Move two or two, or mix into groups for use on - ridge 1 < 勖 sad fixed link. When the dynamic fixation of the spinal rod device is performed, the spinal group 20 is entangled. The vertebral body of the vertebral body 80 22 is tightly fixed, and the έβ is hunted by the squeezing body. There are a plurality of rivets in the receiving end 211 of the nail member 21, and there is an elastic body 40, and the connection The rod 3 is inside/and rushed, so that the nail group 20 is robbed, and has an elastic level so that the connecting rod 30 is connected in series 'each:: 3 〇 has micro-motion, and the indirect nature is not completely fixed and locked. : 80 pushers, with micro-motion and the phenomenon of the other dynamic fixed vertebral body fusion. When the vertebral body W is placed on the vertebral body W, the hemispherical head is placed at 5 〇, and is fixed in the ridge push ring. One space reserved for the space 〇, the nail set receiving seat, the vertebral needle set 60 and the connecting rod 3 〇^成—buffer° so 'but though the snail enters the fixed ridge:: the screw is “locked and fixed”, but there is still a certain degree of 81, and the vertebral body 'movability with other segments 'It will not be completely fixed, 200920307 will cause vertebral body fusion phenomenon.
