Trocar Seal Design [PDF]

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. |
