Abrégé anglais




This group of inventions provides means and methods for preventing the
damaging portions of surgical tools, such as laparoscopic devices, from
adversely contacting tissues and organs that are not in the desired field of
surgery. As such, the present disclosure pertains to any form of a warning or
positioning device or methods, including those that are facilitated via
software
that are adapted and arranged for use in tracking portions of surgical
instruments
during laparoscopic surgery or other medical procedures. Such systems include
those that are adapted and arranged to provide a warning to the surgeon or
other
medical personnel regarding the positional status of an instrument, and those
that are adapted and arranged for disabling or attenuating the portions of
those
instruments that might be dangerous to a patient when a dangerous portion of
the instrument is near or outside the desired, or denominated, field of
surgery.
Data relating to the position and orientation of the instrument and of the
position
of a safe zone within which the instrument can be kept safely is optionally
(preferably) stored throughout a medical procedure for later playback for
training
purposes or for ensuring that a patient was not injured during a medical
procedure.
