Abstract
A head clamp for neurosurgery is described that includes a member for at least partially encircling the head of a subject. The first end and second end of the head clamp include first and second skull attachment portions for attaching the member to the head of a subject. A position setter, such as an indexing mechanism, is also provided that allows the member to be moved or indexed between at least two repeatable relative positions.
Claims16
A head clamp for neurosurgery, comprising:
- a member configured to at least partially encircle the head of a subject;
- at least first and second skull attachment portions configured to attach the member to the head of the subject;
- and
- an indexing mechanism that allows the member to be indexed between at least two repeatable relative positions when the head clamp is attached to the head of the subject, the at least two repeatable relative positions having a known position relative to each other,
- wherein the indexing mechanism is configured to provide tactile feedback to a user to differentiate the at least two repeatable relative positions from other positions of the member when the head clamp is attached to the head of the subject.
