ABSTRACT
A surgical device for endoscopic surgical procedures capable of preventing injuries to internal organs during insertion. The surgical device can include one or more of the following: a multiple system of sharp blade edges, a mechanical tissue protection device that includes a series of thin plastic guards sliding along the sides of the planar knives and having an angle between their edges smaller than that of the cutting knife edges, one or more fixed conical deflectors to expand the cut tissue passage leaving the guards to contact tissue contact only at their tips, an insufflation passage configured to transport fluid into the body cavity during penetration, a locking system for the guards that prevents accidental reuse of the cutting features, and/or an ergonomic design which facilitates handling.

ADDITIONAL INFORMATION
This broadly patented Trocar allows ease and speed of sharp penetration through the abdominal wall yet provides safe, blunt entry into embedded potential spaces such as the peritoneal cavity.  The ERBLAN Trocar has the potential to virtually eliminate unintended damage to the viscera or the great vessels.  It also has the the ability to bypass the current practice of creating a pneumo-peritoneum before closed Trocar placement.  Thus it can eliminate the independent risks of Veress needle insertion and the time required for needle placement and creation of a pneumo-peritoneum through a small bore needle device.
 
Although laparoscopic surgery is generally safe, unintentional injury rates still occur at a rate of roughly six per thousand cases.  Approximately five percent of injured patients will die.  The currently available "shielded" and bladeless" Trocars have not succeeded in lowering the incidence of injury.  The ERBLAN Trocar has the potential to significantly reduce the morbidity and mortality associated with laparoscopic and other endoscopic procedures.  The cost of manufacturing the ERBLAN Trocar is expected to be significantly lower than current devices due to the reduced parts count and simplicity of design.  With this significantly safer Trocar that combines the functions of insufflation with ease of penetration in a simple to manufacture instrument, ERBLAN is poised to capture a large percentage of the Trocar market.
