Description

Technical Field

[0001] This utility model relates to the field of artificial vertebral body technology, specifically an adjustable intelligent artificial vertebral body. Background Technology

[0002] Vertebral tumors, tuberculosis, fractures, and other factors can often lead to severe vertebral damage, causing spinal fractures, instability, and symptoms of neurological and spinal cord damage, even resulting in paraplegia. These patients often require surgery to remove the affected vertebra, allowing for adequate decompression of the spinal cord, thereby relieving pain and improving neurohormonal function. However, surgery causes local bone defects and disrupts spinal continuity, severely affecting spinal support function and stability. Therefore, restoring spinal continuity and rebuilding spinal stability is crucial. Among various methods of spinal reconstruction, artificial vertebrae are frequently used. These artificial vertebrae are integrated with the upper and lower vertebrae in the body to reconstruct defects after spinal resection.

[0003] For example, application number CN202121474056.2 discloses an artificial vertebral body. A specific embodiment of this artificial vertebral body includes: an upper end, a middle part, and a lower end; both the upper surface of the upper end and the lower surface of the lower end have multiple protrusions; the middle part of the vertebral body is a porous structure formed by multiple rods and having multiple through holes. This embodiment can improve the early integration strength between the artificial vertebral body and the upper and lower vertebral bodies in the human body, promote bone ingrowth, and solve the problems of artificial vertebral body subsidence and stress shielding.

[0004] However, the above-mentioned devices still have some problems in use: because the length of the artificial vertebra is fixed, it cannot adapt to various usage needs. Each different patient needs a specific size of artificial vertebra, and there are many types of stock. When connecting the artificial vertebra to the bone, it is usually fixed by screws after the connecting part on the vertebra fits into the bone. However, since it is usually fixedly connected to the vertebra, it is inconvenient to connect in different situations, and the adaptability is low. In order to solve the above problems, the inventor proposed an adjustable intelligent artificial vertebra. Utility Model Content

[0005] To address the issues of fixed-length artificial vertebrae, which cannot adapt to diverse usage needs, the requirement for specific specifications of artificial vertebrae for each patient, the large variety of stock available, and the common practice of connecting artificial vertebrae to the skeleton by fitting the connecting part of the vertebrae to the skeleton and then fixing it with screws, the present invention aims to provide an adjustable intelligent artificial vertebra.

[0006] To solve the above technical problems, the present invention adopts the following technical solution: an adjustable intelligent artificial vertebra, including a first support member, a second support member, and a connecting member. The first support member, the second support member, and the connecting member are all provided with replacement components. A connecting cylinder is fixedly provided on one side of the first support member. The first support member and the second support member are both provided with protrusions on the side away from the connecting cylinder. Screws are threaded into the connecting member. Adjustment components are connected to the connecting cylinder and the second support member.

[0007] The adjusting assembly includes a limiting groove, which is formed on the inner surface of the connecting cylinder. A limiting block is slidably disposed in the limiting groove, and a round rod is fixedly disposed between the limiting blocks. The end of the round rod away from the first support member is fixedly connected to the second support member. A first annular conical block is fixedly sleeved on the outer surface of the round rod. Several first annular conical blocks are provided, and an array of the first annular conical blocks is distributed on the outer surface of the round rod. A hollow circular plate is fixedly disposed on the side of the connecting cylinder near the second support member. A square groove is formed on the inner surface of the hollow circular plate. A spring is fixedly disposed on the inner surface of the square groove. Several square grooves are formed, and an annular array of the square grooves is distributed on the inner surface of the hollow circular plate. A connecting plate is fixedly disposed on the other end of the spring. A second semi-conical block is fixedly disposed on the other end of the connecting plate. The first annular conical block and the second semi-conical block are in movable contact. A sliding groove is formed on the inner surface of the square groove. A slider is slidably disposed in the sliding groove. The slider is fixedly connected to the connecting plate. Three springs are distributed in an array between the square groove and the connecting plate.

[0008] Preferably, the replacement component includes a connecting block, which is fixedly connected to one side of the connecting member. The connecting block has a circular hole, and the sides of the first support member and the second support member are both provided with connecting grooves. The connecting block is movably inserted into the connecting grooves. The upper surfaces of the first support member and the second support member are threaded with bolts, and the ends of the bolts movably pass through the circular hole.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0010] 1. This utility model allows you to first determine the required length of the cone. After determining the length, subtract the distance between the first and second support members from the determined cone length to obtain the required extension value. Then, draw the value on the outer surface of the connecting cylinder. After that, you can pull the second support member to move the round rod, so that the first annular cone block fitted on its outer surface can contact the second semi-circular cone block. Through the cooperation of the spring and the connecting plate, the second semi-circular cone block moves into the hollow round plate. When it is in contact with the outer surface of another first annular cone block, it cannot move backward due to the influence of the previous first annular cone block. This process continues until the end of the round rod is aligned with the scale. Then, you no longer need to pull the second support member, thereby extending the length of the equipment and facilitating adjustment.

[0011] 2. This utility model can replace different connectors according to the actual situation. The connecting block set on the side of the connector can be inserted into the connecting groove, and then the bolt can be made to pass through the round hole to improve its practicality.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Example 1: As Figure 1-4As shown, this utility model provides an adjustable intelligent artificial vertebra, including a first support member 1, a second support member 12, and a connecting member 2. The first support member 1, the second support member 12, and the connecting member 2 are all provided with replacement components 3. A connecting cylinder 4 is fixedly provided on one side of the first support member 1. A screw 21 is threaded into the connecting member 2. An adjustment component 5 is connected to both the connecting cylinder 4 and the second support member 12.

[0020] The adjusting component 5 includes a limiting groove 51, which is formed on the inner surface of the connecting cylinder 4. A limiting block 52 is slidably disposed within the limiting groove 51. A round rod 53 is fixedly disposed between the limiting blocks 52. The end of the round rod 53 away from the first support member 1 is fixedly connected to the second support member 12. A first annular conical block 54 is fixedly sleeved on the outer surface of the round rod 53. A hollow circular plate 55 is fixedly disposed on the side of the connecting cylinder 4 near the second support member 12. A square groove 56 is formed on the inner surface of the hollow circular plate 55. A spring 57 is fixedly disposed on the inner surface of the square groove 56. Several square grooves 56 are formed and arranged in a circular array on the inner surface of the hollow circular plate 55. A connecting plate 58 is fixedly disposed on the other end of the spring 57. A second semi-conical block 581 is fixedly disposed on the other end of the connecting plate 58. The first annular conical block 54 and the second semi-conical block 581 are flexibly connected. To achieve the desired length of the cone, first determine the required length of the cone. Then, subtract the distance between the first support 1 and the second support 12 from the determined cone length to obtain the required extension value. Draw this value on the outer surface of the connecting cylinder 4. Then, by pulling the second support 12, the round rod 53 can be moved, allowing the first annular cone block 54 fitted on its outer surface to contact the second semi-circular cone block 581. Through the cooperation of the spring 57 and the connecting plate 58, the second semi-circular cone block 581 moves into the hollow round plate 55. When it comes into contact with the outer surface of another first annular cone block 54, it cannot move backward due to the influence of the previous first annular cone block 54. This process continues until the end of the round rod 53 aligns with the scale. Then, the second support 12 is no longer pulled, thus extending the length of the equipment for easy adjustment.

[0021] Both the first support member 1 and the second support member 12 have protrusions 11 on the side away from the connecting cylinder 4.

[0022] By adopting the above technical solutions, the stability of the connection with the bone can be improved.

[0023] A sliding groove 59 is provided on the inner surface of the square groove 56, and a slider 591 is slidably provided in the sliding groove 59. The slider 591 is fixedly connected to the connecting plate 58.

[0024] By adopting the above technical solution, the connecting plate 58 is limited to prevent it from detaching.

[0025] There are three springs 57, and the springs 57 are arranged in an array between the square groove 56 and the connecting plate 58.

[0026] By adopting the above technical solution, the stability of the second semi-conical block 581 is improved.

[0027] A plurality of first annular conical blocks 54 are provided, and the first annular conical blocks 54 are arrayed on the outer surface of the round rod 53.

[0028] By adopting the above technical solution, it is convenient to perform limit setting after adjustment.

[0029] Example 2: Figure 1 As shown, the replacement component 3 includes a connecting block 31, which is fixedly connected to one side of the connector 2. The connecting block 31 has a round hole 32. The sides of the first support member 1 and the second support member 12 are both provided with connecting grooves 33. The connecting block 31 is movably inserted into the connecting grooves 33. The upper surfaces of the first support member 1 and the second support member 12 are threaded with bolts 35. The ends of the bolts 35 movably pass through the round hole 32. Different connectors 2 can be replaced according to the actual situation. The connecting block 31 on the side of the connector 2 can be inserted into the connecting groove 33, and then the bolts 35 can pass through the round hole 32 to improve its practicality.

[0030] Working principle: In use, the required length of the cone can be determined first. After determining the length of the cone, the distance between the first support member 1 and the second support member 12 is subtracted from the determined length of the cone to obtain the required extension value. This value is then drawn on the outer surface of the connecting cylinder 4. Then, by pulling the second support member 12, the round rod 53 can be moved, causing the first annular cone block 54 fitted on its outer surface to contact the second semi-conical block 581. Through the cooperation of the spring 57 and the connecting plate 58, the second semi-conical block 581... 1. Move towards the interior of the hollow circular plate 55. When it comes into contact with the outer surface of another first annular conical block 54, it cannot move backward due to the influence of the previous first annular conical block 54. This process continues until the end of the circular rod 53 aligns with the scale. Then, the second support member 12 is no longer pulled, thereby extending the length of the equipment and facilitating adjustment. Different connectors 2 can be replaced according to actual conditions. The connecting block 31 on the side of the connector 2 can be inserted into the connecting groove 33, and then the bolt 35 can be passed through the circular hole 32 to improve its practicality.
