Abstract

The invention provides a tumor biopsy apparatus, and relates to the technical field of medical apparatus and instruments. By the aid of the tumor biopsy apparatus, the problem of deficiency of tumor biopsy apparatuses suitable for extracting tumor samples during endoscopic surgery can be solved. The tumor biopsy apparatus comprises a biopsy gun and a puncture needle. The biopsy gun comprises a shell with a cavity, a sleeve is mounted in the cavity, an end of the sleeve extends out of the cavity, a first handle is mounted on the sleeve, the sleeve is provided with a puncture needle accommodating cavity along the length direction, the first handle can drive the sleeve to slide along the cavity, and a fixing assembly for fixing the puncture needle is mounted on the shell; a sample injection groove is formed in an end of the puncture needle, and the puncture needle is connected with the shell by the fixing assembly. The tumor biopsy apparatus has the advantage that tumor can be sampled by the aid of the tumor biopsy apparatus during endoscopic surgery.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a tumor biopsy device. Background technique [0002] The incidence of tumors is getting higher and higher, which makes the treatment of tumors more urgent. Tumor biopsy is the most accurate way to confirm the nature of tumors. [0003] Tumor biopsy mainly includes needle biopsy and open biopsy. Needle biopsy is usually unable to obtain clear pathological results due to the small amount of tumor tissue. Only a small amount of tumor tissue is required for tumor diagnosis, and laparotomy causes relatively large trauma. [0004] Laparoscopic surgery can reduce trauma and speed up recovery, which is very practical for cases where only the nature of the tumor needs to be clarified. However, there is currently no tumor biopsy device suitable for use in laparoscopic surgery. At the same time, the texture of the tumor is brittle compared with normal tissue, and has rich blood ...
