Minimally traumatic trocar apparatus and kit for subcutaneous medication delivery

A minimally traumatic trocar system for delivering one or more medication pellets to a subcutaneous insertion site, the minimally traumatic trocar system comprising:

• a blunt cannula with a tubular cannula body, wherein a surface of an anterior end of the tubular cannula body includes a smooth edge, wherein the blunt cannula is formed with a medication slot disposed along the tubular cannula body;
• a cannula handle fixedly coupled to the tubular cannula body;
• an obturator that includes an anterior rounded tip and an obturator body, wherein the obturator body includes at least one opening located along the obturator body, in which the opening forms a passage from an exterior of the obturator body to an interior of the obturator body;
• an obturator handle fixedly coupled to the obturator body;
• a first coupling element proximate to the cannula handle that includes a notch, and a second coupling element proximate to the obturator handle that includes a tab;
• wherein the notch interfaces with the tab such that the anterior rounded tip of the obturator extends past the anterior end of the blunt cannula;
• wherein the blunt cannula and the obturator operate as a single unit during insertion into the subcutaneous insertion site;
• wherein the obturator includes a posterior end having a receptor that interfaces with tubing to receive a hydrodissecting fluid and deliver the hydrodissecting fluid through the interior of the obturator body and out of the opening;
• the obturator is removed from the tubular cannula body;
• and
• the anterior rounded tip of the obturator pushes the one or more medication pellets through the tubular cannula body to the subcutaneous insertion site.
