PROBLEM TO BE SOLVED: To provide a biopsy device which prevents the tissue of an object to be examined from being damaged due to erroneous operation or malfunction.SOLUTION: The biopsy device includes: a support base (36) for supporting the object (28)to be examined a compression plate (38) for compressing and holding the object (28) to be examined against the support base (36) a biopsy needle moving mechanism for moving a biopsy needle (52) to pierce the biopsy part of the object (28) to be examined through an opening (44) formed on the compression plate (38) in a plane along the compression plate (38) and in directions perpendicular to the compression plate (38) a determining section (84) for determining whether or not the biopsy needle (52) has pierced the object (28) to be examined and a movement limiting section (82) for limiting movement of the biopsy needle (52) within a plane perpendicular to the piercing direction of the biopsy needle (52) when the determining section (84) determines that the biopsy needle (52) has pierced the object (28) to be examined.COPYRIGHT: (C)2010,JPO&INPIT【課題】誤操作や誤動作によって検査対象物の組織を損傷することのないバイオプシー装置を提供する。【解決手段】検査対象物(28)を支持する支持台(36)と、前記支持台(36)に対して前記検査対象物(28)を圧迫して保持する圧迫板(38)と、前記圧迫板(38)に形成された開口部(44)を介して前記検査対象物(28)の生検部位に刺入される生検針(52)を、前記圧迫板(38)に沿った面内及び前記圧迫板(38)の面に直交する方向に移動させる生検針移動機構と、前記検査対象物(28)に対して前記生検針(52)が刺入されているか否かを判定する判定部(84)と、前記判定部(84)により前記検査対象物(28)に前記生検針(52)が刺入されていると判定された場合、前記生検針(52)の刺入方向と直交する面内での前記生検針(52)の移動を制限する移動制限部(82)とを備える。【選択図】図3
