PROBLEM TO BE SOLVED: To provide an obturator for atraumatic hip joint access.SOLUTION: An obturator 10 provides access to a joint through an articular capsule surrounding the joint. A distal end of the obturator has a first distal location with a first width dimension and a second distal location with a second width dimension, wherein the second distal location is proximal to the first distal location, and the second width dimension is greater than the first width dimension. A retractable blade can extend from the obturator to be exposed between the first distal location and the second distal location. |
