Document Type and Number:
Japanese Patent JP6651641
Kind Code:
B2
Abstract:
A surgical head fixation apparatus according to the present invention includes: a head holder for holding the head of a patient; an articulated link unit which supports the head holder and which is composed of a plurality of link sections; and a support base unit which has a support shaft supporting the articulated link unit and which is to be detachably mounted to an operating table on which the patient is to be placed. The articulated link unit includes at least one link-shaped clamping operation unit which constitutes a link section(s) and which has an operating lever. The link-shaped clamping operation unit has, as pivot axes, at least a first axis and a second axis which are parallel to the support shaft, and a third axis extending in the axial direction of the link-shaped clamping operation unit. The state of the link-shaped clamping operation unit can be switched, through the operation of the operating lever, between three modes: a clamped state in which a pivoting movement on the first axis and a pivoting movement on the second axis are simultaneously locked, an unclamped state in which a pivoting movement on the third axis becomes possible, and a ready-to-clamp state which is an intermediate state between the unclamped state and the clamped state and in which the pivoting movement on the third axis is locked, while the pivoting movement on the first axis and the pivoting movement on the second axis are unlocked.
