Description

technical field [0001] The invention relates to the technical field of kidney puncture, in particular to a biopsy puncture device for nephrology. Background technique [0002] Puncture biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors, because the limb salvage treatment of malignant tumors has become the main trend, which requires stricter requirements on the way and method of biopsy, incorrect biopsy, often due to The tumor will pollute local important structures such as blood vessels and nerve bundles during the sampling process, making it impossible to completely remove the tumor and lead to the failure of limb salvage treatment. Therefore, before biopsy, one should have a full understanding of the nature, staging and treatment of the tumor, and conduct adequate surgical procedures. Plan ahead, and ensure that the needle track for sampling is located on the surgical incision, so that it can be completely removed during the ...
