ABSTRACT:
A flexible insertion device is provided for inserting an endoscope or endoscopic operating instrument through the body wall, typically the chest or abdominal wall. The insertion device comprises a collapsible rigid plastic or metal trocar inserter and a surrounding thin, plastic sheath with an adhesive collar. The insertion device enables the maintaining of air-tight sealing and permits the insertion of rigid, curved instruments without becoming dislodged from the body wall musculature. This eliminates the necessity of multiple puncture and insertion procedures which otherwise would cause additional tissue injuries.
