Usage of K-wire aiming device, connection mode, and auxiliary reduction and fixation device during operation. A A metal handle can be used to adjust a clamp with a 6 mm diameter side convex column clamp that comes in three sizes: 21-44 mm, 27-51 mm, and 46-70 mm; B A self-made universal fixed concave parts that have an inner diameter of 6 mm and the clamp with a side convex column may be added to it. The top butterfly buckle can be used to tighten a carbon fibre rod or a K-wire; C Different length carbon fibre rods in the 5 mm or 6 mm range; D Self-made universal fixed convex with a convex column diameter of 6 mm that can connect to another self-made aiming component or another universal fixed concave. The bottom butterfly buckle can tighten a carbon fibre rod or a K-wire; E Self-made aiming equipment with a concave diameter of 6 mm, a self-made universal fixed convex, an aiming sleeve inner diameter of 2. 5 mm, and a side butterfly buckle that can tighten and fix the K-wire. F With the universal fastening concave connection shown in the schematic picture of the device connection, the clamp can be rotated and fixed 360 degrees; G, H A schematic showing how to operate the K-wire aiming device
