Description

M247174 V. Description of creation (1) [New type belongs to this creation, especially the rotation inside the planting plant which has more than connecting pieces. [Previous technique is that the spine, stand, bend, and must be kept in the most multiple discs, and gradually degenerate, shape, resulting in improper spine movement posture and compression of the surrounding disc support and atrophy or deformation therapy It is based on the connection of the positioning bones to obtain the appropriate postures such as the squat and other postures of the new type of rear vertebrae. The state of the body is composed of the old vertebrae and the vertebrae will be compressed. When the injury, the nerves to avoid , Tendon open, intervertebral; and the current technical field of spinal internal fixation for spinal internal fixation using the spine, so that the spine should be used as a positioning support] is to provide a Jinzu ® m — pieces with = Position of the edge; I »& = = ° 卩, and the joint hole of the connector is located in the slot, which can effectively prevent cattle; The control can make the human body move freely, and in adjacent ridges, that is, the adjacent intervertebral discs will gradually be driven to the surrounding nerves. It is easy to cause the spine to avoid spinal vertebrae. The disc is reset to the intervertebral disc fixator which is normally located in the spine. The fixator, such as the announcement device, is a new patent case of the human sitting and restraining system. Therefore, the body is adjacent to the spine. Gradually narrowing, atrophy, or injury due to accidental bone injury or disc atrophy, changing the injured spine, so that the spine can be restored to the intervertebral disc position, and the injured spine must have a disc that shrinks or becomes damaged Damage; shape, the bones are treated by vertebrae that are not used, and the spine No. 517574 is published in the Republic of China

M247174 V. Creative Instructions (2) Patent Gazette of January 11, 2012, Application No. 90208804, please refer to Figures 11 and 12 for the conventional spine A three-dimensional exploded view of the internal fixator and a side sectional view of the connecting element, which include: a plurality of implanted elements A, the straight-in element A is a cylinder, one end of which has an implant thread A 1 of an appropriate length, With respect to the other end of the implant thread A 1, there is an external locking thread A 2 of an appropriate length, and a convex ring A 3 is provided between the two threads. The convex ring A 3 is spherical on one side of the external locking thread A 2. Curved surface A 4; a plurality of connecting elements B, the connecting element B is an elongated plate, which has two planes parallel to each other, one end of the two planes has a first through hole B1 perpendicular to the plane direction, socket In the locking thread A 2 outside the above-mentioned implant element A, the first through holes B 1 located at two end edges of the plane each have a spherical annular concave edge B 2, and the other end of the first through hole B 1 has a The second through hole B 3 parallel to the above plane corresponds to one of the positions of the second through hole B 3 Surface has a convex portion, which protrudes from the surface portion having a through-hole to the second through B 3 B 4 of fixing holes;

A first-section rod C is passed through the second through hole B 3 provided in the connecting element B; a plurality of fixing screws D are provided in the fixed screw hole B 4 of the connecting element B; a plurality of pad elements E are arranged Above the connecting element B, there is a through hole E 1 of appropriate size in the center, which is socketed with the locking thread A 2 outside the implanting element A, and one end surface of the connecting element B is a spherical curved surface E 2. The other end surface of the spherical surface E 2 is a set of connecting planes E 3;

M247174 V. Creation instructions (3) A plurality of external locking elements F. The external locking element F is a cylinder with a screw hole F 1 in the center, which is screwed onto the locking thread A 2 outside the implant element A, and the pad The connecting element E-end is a set of connecting plane F 2. There are still many defects in the conventional spinal internal fixation device in use, for example: 1. The implant element A is on the external locking thread A 2-the side is a spherical curved surface A 4, and the spherical curved surface A 4 is connected with The spherical annular concave edge B 2 of the first through hole B 1 of the component B is matched, and the arc-shaped contact is not fixed, and it is easy for the implanted component A to rotate axially. 2. The implanted component is matched with a spherical curved surface A 4 and a spherical annular concave edge B 2. There is no contact or fixed holding between the implanted component A and the connecting component B. After the implanted component A is implanted into the spine With the movement or displacement of the spine, it is easy to cause loosening and shaking between the implant element A and the connecting element B. 3. The pad element E is placed in the spherical annular concave edge B 2 of the connecting element B without any fixing, so that the pad component E is easily displaced or rotated in the spherical annular concave edge B 2, and further Affecting the implantation element A also generates displacement wobble. The above-mentioned conventional spinal internal fixator has many defects in the structural design, and causes troubles and inconveniences during use, which is the key to improvement for those who are engaged in this industry: the root cause. [New content] Based on the considerations of the above points, the creator made an in-depth analysis and discussion on the characteristics of orthopedic fixtures, and after various evaluations and

M247174 V. Creation instructions (4) Considering and thoroughly modifying, the original orthopedic use of this creation and the implantation screw with a multi-lateral connection in the screw produces the creation ', and resists the elasticity of deformation [implementation In order to achieve its effect, the function is as follows, please refer to the figure, the solid component of the three-dimensional creation, and the connection.
