A line-shaped paw-type external fixation device for a patella, comprising a type A: two ends of a line-shaped main beam (1) are respectively provided with a pressure regulation fixing part (2), an arc auxiliary beam (4) is arranged below the line-shaped main beam (1), and two ends of the auxiliary beam (4) are respectively provided with two auxiliary fixing parts (5) and fixing needles (6); and a type B: one end is the same with the type A, a b-shaped fixing part (10) is arranged below a q-shaped fixing part (9) at the other end, the b-shaped fixing part (10) is provided with a fixing needle (6), an auxiliary fixing part (11) is arranged in the middle, and two sides of the auxiliary fixing part (11) are provided with a splayed needle seat (12) and an auxiliary fixing needle (13). The design of the external fixation device is suitable for matching with various patella fracture displacements; and generally a patella fracture does not need a surgical operation, and fixing needles can be directly punched into a patella for fixation. The external fixation device is convenient and firm to install, large in adjusting range and minimally invasive, and a patient can be prevented from suffering the pain of a secondary operation. |
