[0022] specific implementation plan
[0023] The present invention is described in more detail below with examples, which optimize the processing and analysis of the materials in the present invention.
[0024] figure 1 The basic structure of a conventional medical biopsy puncture needle is shown, mainly including a needle core 1 and a needle tube 2, the needle core 1 is inserted into the needle tube 2 and can move up and down. In the puncture process of orthopedic surgery, the needle tube mainly plays the role of positioning, and cooperates with the needle core to penetrate the bone marrow.
[0025] Taking Cu10Nb alloy as an example, the specific processing process of the medical biopsy puncture needle of the present invention will be introduced in detail below.
[0026] (1) Using small particle raw materials with a purity ≥ 99.99% (with a particle size of about 10 mm) to obtain Cu10Nb with a mass of 20 kg and a diameter of 80 mm.
[0027] (2) Cut off the riser and polish ...
