PROBLEM TO BE SOLVED: To provide a medical weight anchor capable of serving as a marker which can identify a position visually and easily with a single operation and can pull organs and lesions efficiently and indirectly to a desired direction through the medical weight anchor by attaching to the organs and lesions of interest directly or to an additional biological membrane and bringing equipment that produces gravity or magnetic force closer.SOLUTION: A medical weight anchor includes a weight 2 and a hooking annular rope 3. Wedging of the weight and the hooking annular rope is wedged in a form that does not project to the outer shape of the weight, and the wedge formation is wedged by a seal band which does not allow biological fluid to enter. The weight is formed with a paramagnetic or ferromagnetic material, and the hooking annular rope 2 is formed with a flexible material.COPYRIGHT: (C)2015,JPO&INPIT【課題】目的とする臓器・病変部などを直接あるいは付属する生体膜に取り付け、重力、あるいは、磁力を生じる機器を接近させることによって、効率的に医療用ウエイトアンカーを介して間接的に臓器や病変部を目的の方向に牽引し、単一操作で目視にて容易に位置の同定するマーカーの役割を果たすことができる、医療用ウエイトアンカーを提供する。【解決手段】重錘2と、掛着環状ロープ3とを有し、重錘と掛着環状ロープの楔着は重錘の外形に突出しない形態で楔着形成し、楔着形成は、体液等の侵入しない密封帯で楔着され、重錘は常磁性、若しくは強磁性素材で形成し、楔着環状ロープ2は、可撓性素材で形成した構成とする。【選択図】図1
