Abstract:
A biopsy apparatus (1), comprising: a housing (40), a suction assembly (30), and a needle sleeve adjustment structure (10). The suction assembly (30) comprises a needle sleeve (310); the needle sleeve (310) passes through the distal end of the housing (40), and the distal end of the needle sleeve (310) protrudes from the distal end of the housing (40); the need sleeve (310) passes through the needle sleeve adjustment structure (10), and can move relative to the needle sleeve adjustment structure (10); the needle sleeve adjustment structure (10) is provided on the housing (40), and at least part of the needle sleeve adjustment structure (10) can move along the needle sleeve (310), so as to adjust the distance between the distal end of the needle sleeve (310) and the distal end of the needle sleeve adjustment structure (10). By means of the needle sleeve adjustment structure (10) of the biopsy apparatus (1), the distance between the distal end of the needle sleeve adjustment structure (10) and the distal end of the needle sleeve (310) can be adjusted according to the body structure of different patients, so that the distal end of the needle sleeve (310) can reach target issue. The differences in body structure of different patients can be taken into account, and high flexibility is achieved.
