After penetration, the trocar is withdrawn while the sleeve serves as a working channel for endoscopes, instruments, or CO₂ insufflation.
A trocar obturator is the inner, usually sharply tapered mandrin of a trocar system used to penetrate the skin and tissue and thereby create minimally invasive access to the operative site. After access has been created, the trocar obturator is removed while the remaining trocar sleeve serves as a stable working channel for optics and instruments.
A trocar sleeve is the outer part of a trocar that remains in the tissue after the spine is removed, forming a stable, minimally invasive access channel to the surgical field.
