Detailed Description
The utility model will be further elucidated with reference to the figures 1-4 and the specific examples.
Examples:
As shown in fig. 1 and 2, the first plantar midfoot joint fusion fixing member according to the present utility model is composed of a fixing element 1 and a screw 2.
The external shape of the fixing piece 1 is a cylinder, a first threaded hole 11 and a second threaded hole 12 are formed in the fixing piece 1, the first threaded hole 11 and the second threaded hole 12 are distributed up and down, the first threaded hole 11 and the second threaded hole 12 transversely penetrate through the fixing piece 1, and an assembly hole 15 with double inclined planes is formed in the tail end of the fixing piece 1; the screw 2 is connected with the fixing piece 1 through a first threaded hole 11 and a second threaded hole 12. When a doctor performs operation treatment, the fixing piece 1 is implanted into the bone only through a minimally invasive small opening, after the screw 2 is positioned with the fixing piece 1, the screw 2 is connected with the fixing piece 1 through a threaded hole on the fixing piece 1, and a three-dimensional compound fixing component is formed after the screw 2 is connected with the fixing piece 1, so that better stability can be provided, and recovery of a patient is facilitated.
