Abstract
A guide tube is used for guiding an instrument through a hole within tissue of a patient. The guide tube includes a cannula member defining a passage extending therethrough along an axis. The passage is operable to receive the instrument and guide the instrument through the hole within the tissue of the patient. The guide tube also includes an expansion member that is moveably coupled to the cannula member to selectively move radially between a retracted position and an expanded position relative to the axis of the cannula member. The expansion member is at least partially insertable into the hole when the expansion member is in the retracted position. The expansion member is operable to engage with a surface of the hole when the expansion member is in the expanded position.
