Description

Technical Field

[0001] The utility model belongs to the technical field of fixing guides, and in particular relates to a carbon fiber fixing guide for a posterior ankle hollow nail. Background Art

[0002] When treating diseases such as posterior ankle fracture, large posterior ankle gap, and posterior ankle joint edema, a hollow needle is needed to fix the fracture site. The common surgical steps are to insert a guide needle before inserting the hollow needle, then put the inner hollow of the hollow needle on the guide needle, drill into the bone through the thread at the front end of the hollow needle, and finally remove the guide needle and leave the hollow needle in the fracture end for fixation. However, in this process, the guide needle and the hollow needle need to be inserted into the bone one after another, causing secondary damage to the human joints and bones. In addition, the guide needle is inserted first, and the fracture end that has been fixed by the guide needle is removed after the hollow needle is inserted. This is prone to displacement, resulting in inaccurate positioning of the hollow needle and misalignment of the fixation. Utility Model Content

[0023] See also Figure 1 , Figure 2 As shown, the device fixes the left curved plate 1 and the right curved plate 2 on the outside of the posterior ankle, aligns the guide tube 3 with the position where the hollow needle needs to be inserted, and then fixes the guide tube 3 in the positioning groove 122 through a short bolt 101, so that the hollow needle can be inserted without the need for a guide needle, thereby avoiding displacement and bone damage when the guide needle is removed. The slider 11 and the slide groove 21 are made of hard carbon fiber material, and the connecting belt 13 and the fixing belt 23 are made of flexible carbon fiber material, so that when the ankle is fixed, a gap is formed between the front side and the skin, and the back side is tightly attached to the skin, so that some sterile cotton can be retained in the gap to absorb the blood or pus flowing out of the hollow needle, and at the same time, it is also convenient for the wiping medicine to flow away, so as to maintain the hollow flow at this position.

[0024] In this embodiment, a fixing groove 121 is penetrated through the middle position of the fixing plate 12, and the guide cylinder 3 is composed of a mounting sleeve 31 and a cylinder 32. An inner cylinder 321 is penetrated inside the cylinder 32. The diameter of the inner cylinder 321 is the same as the width of the fixing groove 121, and the inner cylinder 231 is aligned with the position of the fixing groove 121.

[0025] See Figure Figure 3 , Figure 4 As shown, the hollow needle is mainly guided by the guide cylinder 3. The hollow needle passes through the inner cylinder 321 and the fixing groove 121. After the mounting sleeve 31 is fixed, the entire guide cylinder 3 can be fixed, which also ensures that the hollow needle will not be displaced when introduced, ensuring the accurate position of the hollow needle. At the same time, the diameter of the inner cylinder 321 is the same as the width of the fixing groove 121, and the fixing groove 121 will not interfere with the hollow needle.

[0026] In this embodiment, positioning grooves 122 are symmetrically provided on the upper and lower sides of the fixing groove 121, and the depth of the positioning groove 122 is half the width of the fixing plate 12.
