The present invention discloses an ankle surgery image assisting device comprising a bottom plate, at least one first pillar, at least one first abutting member, at least one second pillar and a plurality of second abutting members. The first leg is connected to the bottom plate upright on a central longitudinal axis of the bottom plate. The first abutting member is erectly connected to the bottom plate on a central longitudinal axis of the bottom plate, and the first abutting member is disposed opposite to the first leg. The second pillar is erected to the bottom plate on the central longitudinal axis, and the second pillar is disposed opposite to the first pillar. The first abutting member is between the second pillar and the first pillar. The second abutting members are connected to the bottom plate on the two sides of the vertical axis of the center, and the second abutting members form a space for the abutting members, the first leg and the bottom plate. The bottom plate is adapted to abut the foot plate, the first abutting member is provided to abut the heel, and the second abutting members are provided to abut the two sides of the foot plate. Therefore, the ankle can be fixed and the relative position of the ankle structure can be examined in medical images.本創作係揭示一種足踝手術影像輔助裝置，包含一底板、至少一第一支柱、至少一第一靠抵件、至少一第二支柱及複數第二靠抵件。該第一支柱於該底板之一中心縱軸而直立連接該底板。該第一靠抵件於該底板之一中心縱軸而直立連接於該底板，該第一靠抵件與該第一支柱呈相對設置。該第二支柱於該中心縱軸而直立連接於該底板，該第二支柱與該第一支柱呈相對設置，該第一靠抵件於該第二支柱及該第一支柱之間。該等第二靠抵件於該中心縱軸之垂直二側而連接於該底板，該等第二靠抵件與該等一靠抵件、該第一支柱及該底板形成一放置空間。該底板供抵置足底板，該第一靠抵件供以抵置足跟處，該等第二靠抵件供以抵置足板二側。因此能固定足踝並利於醫療影像中檢視足踝構造之相對位置。
