New description: [New technical field] This creation is about medical instruments for treating spinal diseases, especially an implanted spinous spine that is implanted between two adjacent spinous processes. Open the device. [Prior Art] The skeleton of the human body is used to support the muscles and blood vessels of the building, and the bone path on the back of the human body is the spine. The spine is composed of multi-segment vertebrae. There are many important nerves in the vertebrae. If an aging phenomenon occurs or an accidental injury occurs, a spinal fracture occurs, and the spacing between the vertebrae is reduced and oppressed to the nerve, causing paralysis or pain. Referring to the fourth figure, there is a treatment for the above-mentioned symptoms in the prior art, which uses a cervical vertebra fixator whose main structure is formed by bending the rod to form two longitudinal and concave-convex undulating side bars (5〇). The side bar (5〇) is fitted with the contour of the vertebra (60) by its concave and convex portion and abuts against the vertebra (60) in the patient's body. 'With a metal wire (7〇) wound around the side bar (5〇) and tied On the vertebrae (60) to achieve the effect of positioning the vertebrae (6〇). However, because the cervical vertebra fixator binds the patient's multi-segmented vertebrae together, it is easy to cause the movement between the vertebrae to be difficult, which may cause excessive stiffness of the spine. If the spine is slightly active, it will cause pain and use for a period of time. After that, it is easy to cause loosening or even falling off between the cervical vertebra fixator and each vertebra. Therefore, the stability is poor, and it needs to be improved. [New content] In view of the above-mentioned shortcomings of the prior art, the purpose of the creation is to provide an adjusted spinal spinous process (4) device in the body of a human patient, including two adjacent spinous processes of the vertebrae. In the meantime, the effect of the spine position is indeed achieved. 】, the purpose of the creation, the adjustment of the spine spine expansion device designed by the creation of the 'i俜 and a change 柘 /, the system has eight 咢 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该 该And a lower plate, the upper plate is provided with a screw hole, and a fixing member is coupled in the screw hole, and the bottom end of the fixing member abuts against the lower plate. In the adjustable spine process, the upper plate extends with an upper tab, and the lower plate extends with a lower tab. The screw hole is formed on the upper tab and the bottom end of the fixing member is abutted.掣 该 on the lower tab. The adjustable spinal spinous process expander, wherein the upper and lower plate end portions are located on opposite outer side surfaces of the upper and lower plates, respectively, with two upper clips and two lower clips respectively. There is a perforation. The accommodating spinal spinous process expander, wherein an undercut is formed on an outer side surface of the upper and lower plates. The advantages and advantages of the adjustable spinal spinous process extender provided by the present invention include at least 1. Compared with the prior art, the multi-segment vertebrae are bundled and positioned together, and the present invention only has two adjacent spines at a time. A sudden positioning can avoid affecting the activity between the vertebrae and the excessive stiffness of the spine, or the micro-activity can easily cause pain in the spine to provide better comfort. 2_ can be used with different spine shape to adjust the spacing between the upper and lower plates. The fixing member is combined with the screw hole of the upper plate, and the bottom end of the fixing member is pressed against the lower plate to fix and adjust. The spacing between the upper and lower plates provides a stable support force for the two adjacent vertebrae, and then achieves the strength of the (4) structure. 4 M381378 0 [Embodiment] Please refer to the first figure, the adjustment type of this creation A spinous process of a spine, which has a curved plate (10) and a fixing member (20), wherein the curved plate (10) is bent by a plate (for example, a thin metal plate) to form a relative An upper plate (11) and a lower plate (12) 'the upper plate (11) side laterally extending with an upper tab (13), the upper tab (13) and the lower tab (14) are on the same side A screw hole (131) is disposed in the upper tab (13), and the fixing member (20) is disposed in the screw hole (131). The top end of the fixing member (20) is provided with an external thread (21). In the screw hole (131), and the bottom end of the fixing member (20) abuts against the lower tab (14)' at the end of the upper and lower plates (1, 1 2) and is located on the upper and lower plates ( 11J 2) The opposite outer side faces are respectively longitudinally projecting with two upper clips (111) and two lower clips (121). Each clip (111, 1 21) has a through hole (112, 122) respectively, and the upper and lower sides are respectively inserted. Barbs (113, 123) may be formed on the opposite outer sides of the plates (1, 12), and the teeth provided by the barbs (1, 123) are directed toward the ends of the upper and lower plates (11, 12). Please refer to the second figure. Each vertebra (40) has a spinous process (41) with respect to the back of the human body. The gap between the two adjacent spinous processes (41, 41A) is slightly wider than the front and narrow. Therefore, when the operation is implanted in two adjacent spinous processes (41, 41A), the upper and lower plates (11, 12) are relatively close, upper and lower, by using the bending plate (1〇). After the spacing between the plates (11, 12) becomes smaller, it can be smoothly placed between the spinous processes (41) of the two adjacent vertebrae (40), and the elastic force provided by the curved plate (1〇) can make the upper plate ( 11) abutting against a lower end of a spinous process (41) and a spinous process (41) is engaged between the two upper clips (^), and the lower plate (12) is abutting against the upper end of the other spinous process (41A) and The spinous process (41A) is located between the two lower clips (121) 5 M381378, and the metal wires (30) (such as titanium alloy wires) respectively correspond to the perforations (112, 122) and spinous processes of the lost pieces (111, 121). (41,41A)The two upper and lower clips (111,121) and the spinous process (41.41A) are bound together:: The other inverted hook (113,123) can engage the bone surface of the spinous process (41.41A) to prevent The bent plate (10) is loose. # Please refer to the third figure, the way the creation is positioned adjacent to the spinous processes (41, 41 A) can also correspond to the perforations of the upper and lower clips (111, 121) through the bolts (30A). ) Positioned with spinous processes (41, 41A). The creation can match the shape of the different spinous processes (41, 41 A) and the size of the space formed between them by the bottom end of the fixing member (20) pressing the lower plate (12) to change the upper and lower plates (11) The distance between 12 and 12 allows the upper and lower plates (11, 12) to be surely abutted against the spinous processes (41, 41 A), respectively, thereby obtaining stable support for the vertebrae (4〇).
