[0030] During the operation, the doctor can perform pressure relief operation on the femoral head by operating the pressure relief collection assembly 21, and at the same time, the assembly also has the function of collecting dead bone or necrotic tissue. The design of the pressure relief collection assembly 21 enables the pressure relief and collection processes to be performed simultaneously, greatly improving the operation efficiency.
[0031] Working principle: the decompression and collection assembly 21 can decompress the femoral head by rotating or advancing, and collect the dead bone or necrotic tissue generated during the decompression process, thereby avoiding the residual of the dead bone or necrotic tissue in the surgical area.
[0032] The design of the scraping assembly 31 is to further scrape the necrotic tissue or residue on the surface of the femoral head, and the scraping assembly 31 can be fixed by the positioning assembly 32, so that the doctor can accurately and stably control the scraping assembly 31, thereby achieving accurate scraping of the surface of the femoral head.
