RETRACTABLE CANNULA AND METHOD FOR MINIMALLY INVASIVE MEDICAL PROCEDURE

摘要

Apparatuses and methods for performing minimally invasive medical procedures are disclosed herein. In one example, an apparatus includes an outer elongate body including a lumen extending from a proximal portion to a distal portion of the outer elongate body. An inner elongate body is slidably received within the lumen of the outer elongate body. A distal portion of the inner elongate body is configured to be inserted into a tissue. The outer elongate body and the inner elongate body collectively define a channel to removably receive a tool when the outer elongate body and the inner elongate body are slidably extended from each other. At least one of the tool and the inner elongate body are configured to puncture the tissue.
