The second supporting unit is movably sleeved on the first supporting unit, wherein the second supporting unit comprises a second supporting seat and a second supporting column. The second support seat is provided with a second abutting surface and a second surface opposite to the second abutting surface. The second support column is disposed on the second surface. The fixing part is configured to penetrate through and fix the first supporting column and the second supporting column. The vertebral plate stabilizer of the invention can adjust different lengths according to requirements, thereby increasing the stability of the vertebral plate stabilizer installed on the spine.
Description
Technical Field
The invention relates to a vertebral plate stabilizer, in particular to a stabilizer which can be adjusted and abutted against a vertebral plate.
Background
Referring to fig. 1 and 2, fig. 1 and 2 are views illustrating a state of use of a conventional spinal process stabilizer. The spinal process stabilizer 80 is primarily intended to be positioned between two adjacent vertebrae 90 to reduce compression on the spinal nerves. Further, the spinal stabilization device 80 may be used to support two adjacent vertebrae 90 to increase the distance between the two adjacent vertebrae 90 and thereby reduce the compression of the vertebrae 90 on the nerves.
As shown in fig. 1 and 2, the spinal stabilization device 80 includes a body 81. The opposite ends of the body 81 have abutting portions 81 a. Therefore, when the spinal crest stabilizer 80 is disposed between two adjacent vertebrae 90, the two abutting portions 81a of the body 81 abut on the crests 91 of the two adjacent vertebrae 90, respectively.
Referring to fig. 3, a schematic diagram of a conventional spinal process stabilizer in use relative to a vertebra is shown. However, when the abutting portion 81a of the spinal crest stabilizer 80 abuts against the crest 91, the supporting force provided by the abutting portion 81a is mainly concentrated on the crest 91. Since the spine 91 is a thinner portion of the vertebra 90, the spine 91 is likely to break when the spine 91 is subjected to a long-term force (the break 910a is shown in fig. 3).
On the other hand, since the conventional spinal stabilization device 80 must be installed on the spine 91, the conventional spinal stabilization device 80 cannot be used on the last segment of the lumbar vertebrae and the first segment of the sacrum because the sacrum of the human body does not have a spine.

Detailed Description
Referring to fig. 4 and 5, fig. 4 and 5 are a schematic perspective view and an exploded perspective view of a spinal lamina stabilizer according to an embodiment of the invention. The spinal lamina stabilizer 100 of this embodiment mainly comprises a first supporting unit 10, a collar 20, a second supporting unit 30 and at least one fixing member 40.
Referring to fig. 4 and 5, the first supporting unit 10 includes a first supporting base 11 and a first supporting column 13. The first support seat 11 has a first surface 11a and a first abutting surface 12, and the first support column 13 is disposed on the first surface 11 a. In this embodiment, the first abutting surface 12 is mainly abutted against the vertebral plate 51 of the vertebra 50 (as shown in fig. 11). In one example, the first abutment surface 12 has three radially arranged first concave arcs 14, each corresponding to a triangular area of the vertebra plate 51 abutting against the vertebra 50 and the spinous process 52 (see fig. 11). In some examples, the arc design of the first abutment surface 12 may be designed according to the curvature of the vertebral plate 51 of different patients. Wherein the curvature of the patient's lamina 51 can be obtained using computed tomography.
Referring to fig. 5 and 6, fig. 6 is a schematic cross-sectional view of a spinal lamina stabilizer according to an embodiment of the invention. In the present embodiment, the first supporting pillar 13 is a solid structure. Wherein, the outer surface of the first supporting column 13 comprises a convex arc surface 13a and a concave arc surface 13b which are opposite. Further, the first support column 13 has a plurality of first fixing holes 15. These first fixing holes 15 penetrate from the convex arc surface 13a to the concave arc surface 13b of the first support column 13, and form openings 16 in the convex arc surface 13a and openings 17 in the concave arc surface 13 b. In one example, the first fixing holes 15 may be spaced apart.
Referring to fig. 4 and 5 again, the second supporting unit 30 includes a second supporting seat 31 and a second supporting pillar 33. The second support seat 31 has a second surface 31a and a second abutting surface 32 opposite to each other, and the second support pillar 33 is disposed on the second surface 31 a. In this embodiment, the second abutting surface 32 is mainly abutted against the vertebral plate 51 of the vertebra 50 (as shown in fig. 11). In one example, the second abutment surface 32 has three radially arranged second concave arcs 34, each corresponding to a triangular area of the vertebra plate 51 abutting against the vertebra 50 in connection with the spinous process 52. Similarly, the curvature of the second abutting surface 32 can be designed according to the curvature of the vertebral plate 51 of different patients. Also, the curvature of the second abutment surface 32 may not be the same as the curvature of the first abutment surface 32.
Referring to fig. 5 and 6, in the present embodiment, the second supporting column 33 is a tube and can be sleeved on the first supporting column 13. In one embodiment, the cross-sectional shape of the second support column 33 corresponds to the cross-sectional shape of the first support column 13. The outer surface of the second support column 33 includes opposite convex arc surfaces 33a and concave arc surfaces 33 b. In addition, the second supporting column 33 has a plurality of second fixing holes 35 and 36. The second fixing hole 35 is formed through the second supporting pillar 33 from the convex arc surface 33a, and the second fixing hole 36 is formed through the second supporting pillar 33 from the concave arc surface 33 b. In one example, the second fixing holes 35 and 36 are through holes.
Referring to fig. 5 and fig. 6 again, the collar 20 is mainly used to fit over the first supporting column 13 and the second supporting column 33 to strengthen and fix the first supporting unit 10 and the second supporting unit 30. In this embodiment, the cross-sectional shape of the collar 20 corresponds to the shape of the second support column 33. The outer surface of the collar 20 comprises opposite convex 20a and concave 20b arcs. In addition, the collar 20 has a plurality of first screw holes 21 and a plurality of second screw holes 22. The first screw hole 21 is formed in the collar 20 through the convex arc surface 20a, and the second screw hole 22 is formed in the collar 20 through the concave arc surface 33 b.
Referring to fig. 5 and 7, fig. 7 is a schematic longitudinal sectional view of a spinal lamina stabilizer according to an embodiment of the invention. In one embodiment, as shown in FIG. 5, collar 20 has a small opening 23, a large opening 24, and a stop wing 25. The stop wing 25 is arranged inside one end edge of the collar 20 and surrounds the small opening 23. In the present embodiment, the first supporting column 13 is inserted into the collar 20 from the small opening 23, and the second supporting column 33 is inserted into the collar 20 from the large opening 24 and is sleeved on the first supporting column 13. In addition, the bottom surface of the second supporting column 33 is abutted against the stop wing 25 of the collar 20, so that the distance between the second supporting unit 30 and the first supporting unit 10 can be adjusted by moving the position of the collar 20. In the present embodiment, the first support column 13, the second support column 33 and the collar 20 have the same cross-sectional shape and are non-circular. Therefore, the first support column 13, the second support column 33 and the collar 20 can only move radially, but can not rotate relatively.
Referring to fig. 5 and 6 again, the fixing member 40 is disposed to penetrate through and fix the collar 20, the second supporting unit 30 and the first supporting unit 10. In the present embodiment, the fixing member 40 includes a screw portion 41. Therefore, the fixing member 40 can sequentially penetrate through the collar 20, the second supporting unit 30 and the first supporting unit 10, and is screwed on the collar 20 through the screw portion 41. Specifically, the fixing element 40 passes through the first screw hole 21 of the collar 20, the second fixing hole 35 of the second support column 33, the opening 16 of the first support column 13, the opening 17 of the first support column 13, the second fixing hole 35 of the second support column 33, and the second screw hole 22 of the collar 20 in sequence, and then the screw thread portion 41 of the fixing element 40 is screwed into the second screw hole 22 of the collar 20. In one embodiment, the fixing member 40 further includes a head portion 42, and the head portion 42 and the threaded portion 41 are respectively located at two opposite ends of the fixing member 40. Therefore, when the threaded portion 41 of the fixing member 40 is screwed into the second screw hole 22, the head portion 42 of the fixing member 40 is located in the first screw hole 21. In one embodiment, a nut 43 having external threads may be threaded into the first threaded bore 21 against the head 42 of the fastener 40 to enhance the positioning of the fastener 40.
As will be apparent, the number and the way of inserting the fasteners 40 can be set according to the requirement. In the example of fig. 3, the number of the fixing members 40 is 2, and they are arranged in a cross. In addition, in some examples, the collar 20 may be made of metal, and the first and second support units 10 and 30 are made of a light and elastic material (e.g., plastic). Therefore, the fixing member 40 can penetrate through the first supporting unit 10 and the second supporting unit 30 and be locked on the collar 20.
The method of using the spinal lamina stabilizer 100 of this embodiment is described below. Fig. 7 to 10 are schematic longitudinal sectional views of a spinal lamina stabilizer according to an embodiment of the present invention, fig. 8 is a schematic longitudinal sectional view of the spinal lamina stabilizer, and fig. 9 and 10 are views illustrating different angles of the spinal lamina stabilizer according to an embodiment of the present invention. First, the first supporting unit 10, the second supporting unit 30 and the collar 20, which are sleeved with each other, can be placed between the vertebral plates 51 of two adjacent vertebrae 50. Next, the collar 20 is moved to move the second support unit 30 relative to the first support unit 10 to adjust the distance between the first abutting surface 12 and the second abutting surface 32, so as to properly support the vertebral plate 51 of two adjacent vertebrae 50. After the distance between the first abutting surface 12 and the second abutting surface 32 is adjusted, the fixing member 40 is inserted into and screwed into the collar 20, the second supporting unit 30 and the first supporting unit 10 to fix the collar 20, the second supporting unit 30 and the first supporting unit 10.
As shown in fig. 8-10, the installed spinal lamina stabilizer 100 is secured between two adjacent vertebrae 50. Moreover, the first abutting surface 12 of the first supporting unit 10 and the second abutting surface 32 of the second supporting unit 30 abut against the vertebral plate 51 of two adjacent vertebrae 50, so that the vertebral plate 51 can be stably supported by the first supporting unit 10 and the second supporting unit 30. Therefore, the problem of spine rupture due to concentration of force on the spine of the vertebra 50 can be avoided.
It should be clear that, since the vertebral lamina stabilizer 100 of the present embodiment has the design of the first abutting surface 12 and the second abutting surface 32, the vertebral lamina stabilizer 100 can be installed between the vertebral lamina of the lumbar vertebra 60 and the sacrum 70 according to the requirement. In detail, the vertebral plate stabilizer 100 according to the embodiment of the present invention can be installed on the last segment of the lumbar vertebrae and the first segment of the sacrum.
Referring to fig. 12, an exploded perspective view of a spinal lamina stabilizer according to another embodiment of the invention is shown. The spinal lamina stabilizer 200 of this embodiment is substantially identical in construction to the spinal lamina stabilizer 100 described above, except that the spinal lamina stabilizer 200 does not have the collar 20 design shown in figure 4. The spinal lamina stabilizer 200 of this embodiment mainly comprises a first support unit 210, a second support unit 230, and a fixing member 250. Therefore, after the relative distance between the first supporting unit 210 and the second supporting unit 230 is adjusted, the fixing member 250 can be used to limit the first supporting unit 210 and the second supporting unit 230.
As shown in fig. 12, the structures of the first supporting unit 210, the second supporting unit 230 and the fixing member 250 are respectively the same as the first supporting unit 10, the second supporting unit 30 and the fixing member 40 of the foregoing embodiment, and therefore, the description thereof is omitted. In some embodiments, the first supporting unit 210 includes a first supporting base 211 and a first supporting column 213, wherein the first supporting column 213 may have a plurality of first fixing holes 216. Similarly, the second supporting unit 230 includes a second supporting base 231 and a second supporting column 233, wherein the second supporting column 233 may have a plurality of second fixing holes 235. In one example, each of the first fixing holes 216 may be a through hole, and each of the second fixing holes 235 may be a screw hole. Therefore, the fixing member 250 can be inserted and fixed in the first supporting column 213 and the second supporting column 233.
In some examples, the first supporting column 211 and the second supporting column 233 may be made of a metal material to increase the stability of the fixing member 250 locked therein. The first support seat 211 and the second support seat 231 can be made of plastic or other light materials, so that the comfort of the spinal plate stabilizer 200 in mounting on the spine can be increased.
In the above embodiments of the present invention, the vertebral plate stabilizer of the present invention can adjust the spacing between the adjacent vertebrae and stably support the adjacent vertebrae by adjusting the relative positions of the first supporting unit and the second supporting unit. In addition, the first abutting surface and the second abutting surface of the vertebral plate stabilizer of the invention have the structural design of concave cambered surfaces, and can abut against the triangular area connected with the vertebral plate and the spinous process of the vertebra, so that the supporting area can be increased, and the fracture of the spinous process caused by stress can be avoided.
In addition, the cross section of the cannula, the first supporting unit and the second supporting unit is designed to be convex at one side and concave at one side, and the concave side faces the inner side of the spine. Therefore, when the vertebral plate stabilizer is installed on the vertebra, the nerve on the inner side of the vertebra can not be pressed.
Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
