For example, internal support and fixation of bone fragments after comminuted fractures. When the bone block grows well, the stainless steel needle tube 3吋 needs to be taken out, and the temperature is inserted into the stainless steel needle tube 3 through the insertion hole 2 to a second temperature. External object (not shown in FIG. 1) to cool the memory gold strip 4 such that the memory gold strip 4 is shrunk into the stainless steel needle tube 3, and then the stainless steel needle tube 3 is taken out from the human bone. By taking out the stainless steel needle tube 3 in this way, the number of sickles can be reduced to reduce the suffering of the patient. The external object may be, but not limited to, a stainless steel needle that can be inserted into the stainless steel needle tube 3 through the insertion hole 2 and connected to the memory gold strip 4 to make the memory gold strip 4 The temperature is lowered to the second temperature.
[0034] 以上仅为本实用新型的优选实施例， 并非因此限制本实用新型的专利范围， 凡 是利用本实用新型说明书及附图内容所作的等效结构或等效功能变换， 或直接 或间接运用在其他相关的技术领域， 均同理包括在本实用新型的专利保护范围 内。 The above is only a preferred embodiment of the present invention, and thus does not limit the scope of the patent of the present invention, and the equivalent structure or equivalent function transformation made by the specification and the drawings of the present invention, or directly or indirectly In other related technical fields, the same is included in the scope of patent protection of the present invention.
工业实用性  Industrial applicability
[0035] 相较于现有技术， 本实用新型所述用于固定骨头的记忆合金骨架采用了上述技 术方案， 达到了如下技术效果： 本实用新型可以降温的方式使得记忆合金骨架 收缩， 使得取出所述记忆合金骨架吋减少了在人体上切幵的面积， 降低了手术 的风险， 同吋也减轻了病人的痛苦。  [0035] Compared with the prior art, the memory alloy skeleton for fixing bones of the present invention adopts the above technical solution, and achieves the following technical effects: The utility model can cool down the memory alloy skeleton by shrinking, so that the body alloy is taken out The memory alloy skeleton reduces the area of cutting on the human body, reduces the risk of surgery, and reduces the pain of the patient.
