APPARATUS HAVING AT LEAST ONE ACTUATABLE PLANAR SURFACE AND METHOD USING THE SAME FOR A SPINAL PROCEDURE

摘要

A medical device includes a link assembly and an actuating member coupled to the link assembly. The actuating member is configured to actuate the link assembly. A member having a substantially planar surface is coupled to the link assembly. The link assembly is configured to move the member having a substantially planar surface through a range of motion between a first location substantially adjacent the actuating member and a second location at a distance from the actuating member. The substantially planar surface is configured to contact at least a portion of a bone structure (e.g., a vertebra) or a soft tissue area of a patient. A cannula is configured to percutaneously access the patient and the actuating member is moveably disposable within the cannula. The cannula has a cross-sectional shape with at least one substantially planar surface on an inner wall.
