Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically a porous Niti alloy lamina. Background Art

[0002] The spine is the central axis of the human body, bearing the body's weight and the pressure from various activities. When the spine is injured due to fractures, dislocations, degenerative diseases, or other reasons, its stability is compromised. NiTi alloy lamina can serve as a support structure, placed at the site of the damaged lamina to help maintain the spine's normal physiological curvature and stability, preventing further deformation and damage. NiTi alloy, or nickel-titanium shape memory alloy, possesses shape memory effect and superelasticity. At a certain temperature, it can return to a pre-set shape, which is highly advantageous for lamina implantation and fixation. Simultaneously, its superelasticity allows the material to undergo significant deformation under stress without permanent plastic deformation, better adapting to the body's physiological activities.

[0003] Most existing lamina are long and narrow, fixed to both sides of the spine after surgery and then secured with screws. However, because patients have different heights and body types, the main damaged areas need to be reinforced and fixed, which requires the lamina to have a certain degree of adjustability.

[0004] Therefore, this utility model provides a porous NTI alloy veneer plate to solve the above problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this invention provides a porous NTI alloy veneer plate, which solves the aforementioned problems.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a porous Niti alloy lamina, comprising a lamina body, a limiting groove formed inside the lamina body, a slider slidably connected inside the lamina body, the two sides of the slider being slidably connected to the inside of the limiting groove, a secondary positioning hole formed inside the slider, V-shaped end recesses formed at both ends of the lamina body, V-shaped side recesses formed on both sides of the lamina body, and a through groove formed inside the lamina body.

[0007] Furthermore, the outer wall of the vertebral lamina body is provided with an arc groove.

[0008] By adopting the above technical solution, it conforms to ergonomics and allows it to bend through the arc groove.

[0009] Furthermore, a main positioning hole is provided inside the vertebral lamina body.

[0010] The above technical solution is used to fix both ends of the vertebral lamina body with screws.

[0011] Furthermore, a first auxiliary positioning hole is provided inside the vertebral lamina body.

[0012] By adopting the above technical solution, a suitable position is selected for screwing in the main positioning hole to assist in the positioning of the vertebral lamina body.

[0013] Furthermore, second auxiliary positioning holes are provided at both ends of the vertebral lamina body.

[0014] The above technical solution is used to initially fix the main body of the vertebral lamina, which facilitates the subsequent fixing operation of the main positioning hole.

[0015] Furthermore, each edge of the vertebral lamina body should be polished smooth to present a certain curvature.

[0016] The above technical solution is used to protect human tissue and prevent sharp edges from scratching some muscle tissues in the human body.

[0017] Beneficial effects

[0018] This invention provides a porous NTI alloy vena cava. Compared with the prior art, it has the following advantages:

[0019] 1. This porous NTI alloy lamina first uses a second auxiliary positioning hole with screws to initially fix the lamina body. Then, it can be further fixed with screws through the main positioning hole. The sliding slider can be adjusted along the limiting groove. When the slider moves to the appropriate position, the key areas can be reinforced through the secondary positioning hole and screws. The through groove is used to pass various objects to facilitate operation during surgery. The first auxiliary positioning hole can be used to assist in reinforcement. For some transition areas of the lamina body, where the main positioning hole with a larger diameter is not used for fixation, the secondary positioning hole with corresponding screws can be used for reinforcement.

[0020] 2. The porous structure of the Niti alloy lamina, with its arc grooves, end V-shaped recesses, and side V-shaped recesses, makes it more ergonomic. When patients move, the lamina will inevitably deform as the bones and joints move. However, the arc grooves, end V-shaped recesses, and side V-shaped recesses make the lamina more stable and easier to move when bending, resulting in a more gradual change.

The terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication between two elements. For those skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0028] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0029] Reference Figures 1 to 4This application provides a porous NTI alloy lamina, including a lamina body 1. A limiting groove 5 is formed inside the lamina body 1. A slider 6 is slidably connected inside the lamina body 1, with both sides of the slider 6 slidably connected to the limiting groove 5. Secondary positioning holes 7 are formed inside the slider 6. End V-shaped recesses 9 are formed at both ends of the lamina body 1, and side V-shaped recesses 10 are formed on both sides of the lamina body 1. A through groove 11 is formed inside the lamina body 1. A main positioning hole 2 is formed inside the lamina body 1. A first auxiliary positioning hole 3 is formed inside the lamina body 1. Second auxiliary positioning holes 8 are formed at both ends of the lamina body 1.

[0030] In specific implementation: First, the vertebral lamina body 1 is initially fixed by screws through the second auxiliary positioning hole 8. Then, it is further fixed by screws through the main positioning hole 2. The sliding slider 6 can be adjusted along the limiting groove 5. When the slider 6 moves to the appropriate position, the key parts can be reinforced through the secondary positioning hole 7 and screws. The through groove 11 is used to pass various objects to facilitate operation during surgery. The first auxiliary positioning hole 3 can assist in reinforcement. For some transition areas of the vertebral lamina body 1, the main positioning hole 2 with a larger diameter is not used for fixation. Instead, the secondary positioning hole 7 can be used with corresponding screws for reinforcement. The end V-shaped recess 9 and the side V-shaped recesses 10 on both sides of the vertebral lamina body 1 are ergonomically designed so that they can bend synchronously with changes in the bone.

[0031] Reference Figures 1 to 4 In one aspect of this embodiment, the outer wall of the vertebral lamina body 1 is provided with an arc groove 4, and each edge of the vertebral lamina body 1 should be polished smooth to present a certain arc.

[0032] In practice: the arc groove 4 facilitates the bending of the vertebral lamina body 1 with the changes of the bones, and the edges of the vertebral lamina body 1 are polished smooth to present a certain arc to protect human tissue and prevent the edges from scratching some muscle tissues in the human body.

[0033] All electrical devices in this plan are powered by an external power source.

[0034] Working principle: First, the lamina body 1 is initially fixed by screws through the second auxiliary positioning hole 8. Then, it is further fixed by screws through the main positioning hole 2. The sliding slider 6 can be adjusted along the limiting groove 5. When the slider 6 moves to the appropriate position, the key parts can be reinforced through the secondary positioning hole 7 and screws. The through groove 11 is used to pass various objects to facilitate operation during surgery. The first auxiliary positioning hole 3 can be used to assist in reinforcement. For some transition areas of the lamina body 1, the main positioning hole 2 with a larger diameter is not used for fixation. Instead, the secondary positioning hole 7 can be used with the corresponding screws for reinforcement. The arc groove 4, the end V-shaped depression 9, and the side V-shaped depression 10 make it more ergonomic. When the patient moves, the lamina body 1 will inevitably deform with the movement of the bone joints. However, the arc groove 4, the end V-shaped depression 9, and the side V-shaped depression 10 make the lamina body 1 more ergonomic when bending, and the phased changes are more stable.
