Dear All,


I am a doctor student in the Institute for Robotics and Process control,
TU Braunschweig, Germany. I work in a Robot Assisted Endoscopic Sinus
Surgery reserch .

Today most operations in nasal sinuses are accomplished
minimal-invasively through the natural opening of the nose with the help
of an endoscope. The surgeon, holding the endoscope in one hand, does
not see the place of operation directly but a camera picture of it on a
screen. In the other hand she/he usually holds an instrument, e.g. a
special knife used to cut away tissue.Normally, this causes some
bleeding. So a sucker (another instrument) is needed to remove the blood
and the cut tissue from the nose.The surgeon often switches between
these instruments during an operation.This increases the duration of the
operation and makes the process cumbersome and unergonomic for the
surgeon.I we are investigating methods that allow a robotic manipulator
to guide an endoscope during an endonasal operation completely autonomously.

I am devoping a FEM model and simulation of the nasal cavity. To obtain
a biomechanical model of the nasal cavity , it is necessary to derive
the material properties of bone, mucose and cartilage of these structures.

We are looking for this reference. We are a institut of robotic and
unfortunately we have not this journal in our library:WONG BJF, CHAO
KKH, KIM HK, CHU EA, DAO X, GAON M, UN CH, NELSON JS. The porcine and
lagomorphseptal cartilages: Models for tissue engineering and
morphologic cartilage research. Amer. J. Rhinology, vol.15, no.2,pp
109-116, mar-apr. 2000

We will be very thankful if some one could provide us with a pdf article copy.
