2 results about "Complex joint" patented technology

The invention relates to a plate (10) for temporarily bridging fragments of a fracture having a proximal portion (11), a distal portion (12), and an intermediate portion (13) disposed between the proximal portion (11) and the distal portion (12). The proximal portion (11) has a proximal attachment zone (14) adapted to be applied and attached to a first tubular bone (1). The distal portion (12) has a distal attachment zone (15) adapted to be applied and attached to a second tubular bone (2). The intermediate portion (13) is adapted to bridge a joint (3) between the first tubular bone (1) and the second tubular bone (2) and thereby at least one further bone, in particular without attachment to the at least one further bone. The plate (10) has at least one curved region (16, 17) between the proximal attachment zone (14) and the distal attachment zone (15). Furthermore, the invention relates to a method for treating a complex joint fracture, in which in particular such a plate can be used.

The application discloses a kind of microfracture surgery and cavity bone combined injection apparatus.The microfracture instrument designed by the application can more accurately control the depth and angle of microfracture punching by using a level angle sensor and a depth sensor, and the operation result can be displayed in real time by using a liquid crystal display to provide intuitive and accurate operation feedback for doctors.In addition, by improving the unadjustable bending angle of the previous instrument, the drill bit part of the application can flexibly adjust the angle to adapt to various complex joint structures and anatomical features, making it possible to perform surgery in difficult-to-reach areas.The application simplifies the operation while providing a more favorable environment and conditions for cartilage repair, which is expected to improve the treatment effect, avoid the pain and discomfort caused by secondary puncture, and reduce the risk of infection and other surgical risks.
