一种多轴调节精准定位接骨板
By incorporating sustained-release material sheets and drug reservoirs into the bone plate, combined with adjustable hinges and air bladder structures, the problem of maintaining a high concentration of drug release at the fracture site in traditional bone-setting techniques has been solved. This enables phased and continuous drug treatment, achieving sustained and efficient drug release at the fracture site, enhancing treatment efficacy and reducing systemic side effects.

AI Technical Summary
Traditional bone plates lack effective drug delivery methods, making it difficult to maintain high drug concentrations at the fracture site, resulting in limited therapeutic effects and potential systemic side effects.
A multi-axis adjustable precision positioning bone plate is designed. By setting a sustained-release material sheet and a drug reservoir in the groove of the bone plate, combined with the adjustment hinge and linkage airbag structure, the phased and continuous release of drugs can be achieved, ensuring efficient drug penetration at the fracture site.
This method achieves continuous and efficient drug release at the fracture site, enhances treatment efficacy, reduces systemic side effects, and ensures the controllability and stability of the drug release process.

Abstract
Claims
1. A polyaxial adjustment precision positioning bone plate comprising a first bone plate (1), characterized in that: A second bone plate (2) is installed on the left end of the first bone plate (1). An adjusting hinge (3) is provided between the first bone plate (1) and the second bone plate (2). The second bone plate (2) has multiple grooves (8) at the end away from the locking member (5). A slow-release material sheet (10) is provided at the inner end of the groove (8). Multiple side guide grooves (14) are provided on the inner sidewall of the groove (8). The multiple side guide grooves (14) are arranged in a ring shape. The inner end of the groove (8) is provided with a drug reservoir (12) located between the sustained-release material sheet (10) and the outer ejector sheet (17). A water-soluble cover (13) is fixedly connected to one end of the drug reservoir (12) near the sustained-release material sheet (10). A spring (16) is fixedly connected to the lower inner wall of the side guide groove (14). The spring (16) and the side guide groove (14) are slidably connected. The guide bar (15) and the spring (16) are connected to each other.
2. The polyaxial adjustment precision positioning bone plate of claim 1, wherein: The first bone plate (1) and the second bone plate (2) have multiple locking holes (4) on their surfaces, and the inner end of the locking hole (4) is threaded with a stud (6).
3. The polyaxial adjustment precision positioning bone plate of claim 2, wherein: The stud (6) has multiple external threads (7) on its outer end, and a locking member (5) is fixedly connected to the end of the stud (6) away from the locking hole (4).
4. The polyaxial adjustment precision bone plate of Claim 1, wherein: One end of each of the multiple guide crossbars (15) is fixedly connected to an outer ejector plate (17), and a linkage airbag (18) is engaged between the outer ejector plate (17) and the groove (8).
5. The polyaxial adjustment precision bone plate of Claim 1, wherein: The outer side wall of the sustained-release material sheet (10) is provided with outward convex grooves (11), and the inner side wall of the groove (8) is provided with matching grooves (19).
6. The polyaxial adjustment precision positioning bone plate of claim 5, wherein: The slow-release material sheet (10) and the groove (8) are locked together by the matching groove (19) and the outward groove (11).
7. The polyaxial adjustment precision positioning bone plate of Claim 1, wherein: The inner end of the drug reservoir (12) is filled with several repair gels, and the first bone plate (1) and the second bone plate (2) are locked to the bone base by studs (6).
