[0016] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0017] Combination Figure 1-3 The vertebral support 100 can be expanded, including a core rod 101, a support shell 102 fitted on the outer surface of the core rod 101, a top shell 103 and a tail ring 104 are formed at both ends of the support shell 102, two support plates 105 are symmetrically formed on both sides of the support shell 102, a plurality of support bars 106 are arranged in the annular direction between the two support plates 105, and a support plate 105 and a support bar 106 are formed between the support plate 105 and the support bar 106, and between two adjacent support bars 106. A deformation gap 107 extends axially, the top of the core rod 101 is abutted against the top shell 103, and a plurality of annular retaining rings 108 are evenly arranged axially formed at the tail of the core rod 101. The inner wall of the tail ring 104 protrudes to form an annular convex strip 109 supported by the annular retaining ring 108, and gaps 110 are formed between the two sides of the support plate 105 and the top shell 103 and the tail ring 104 respectively, and the two sides of the support strip 106 are respectively connected to the top shell 103 and the tail ring 104.
[0018] When in use, the tail ring 104 is pushed forward and the two support plates 105 are spread outward.
[0019] In this embodiment, the mechanism is driven into a vertebral body with a certain space reserved, and then the tail ring is squeezed. The tail ring is pushed forward due to the squeezing effect, and the tail ring cannot retreat due to the action of the annular convex strip and the annular retaining ring. The support strips are deformed upward and downward respectively to connect the upper and lower support plates. The two support plates are supported in the vertebral body, one above and one below, to treat osteoporotic compression fractures.
[0020] Furthermore, the core rod 101 is hollow inside, and a strip-shaped hole 111 is formed in the core rod 101 near the top shell 103 .
[0021] In this embodiment, it is used to inject bone cement.
[0022] Furthermore, both ends of the deformation gap 107 are expanded respectively.
[0023] In this embodiment, the deformation of both sides of the support bar is facilitated.
[0024] Furthermore, a separation gap 112 is formed in the middle of the supporting shell 102 , and the separation gap 112 is connected to the two deformation gaps 107 .
[0025] In this embodiment, the support bars are deformed and supported upward and downward from the separation gaps respectively.
[0026] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.
[0027] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
