00:00:00
much for introduction i'm i'm pleased to introduce you interrupted this uh abbreviation for come um
00:00:07
complex topic in which is the training system for complex pondering a minimally invasive cancer three
00:00:12
so on let me give for short introduction to initial problem of course
00:00:17
uh factors are i'm fixing operating with k. bus um by
00:00:22
minimally invasive bundling soul to do that's interventions carefree in safe on
00:00:27
this a tiny little bone structures without having any restructure
00:00:31
a long time to activity given practical training is necessary for young surgeons
00:00:35
so that's why we are developing up to this a complete tracking system where assertions can improve
00:00:42
that really scares during the clinic routine and that's your skin character but alone feedback
00:00:48
so on the next slide you can see uh uh the basic prototype um of
00:00:53
tapping the system and you try to transfer the operating room set up
00:00:58
with some um hardware devices uh at first but using interrupted by has been force feedback
00:01:04
so um we cannot first a transfer yeah the c. d. position
00:01:09
from our object uh due to hold up to
00:01:12
our system and otherwise it's possible to transpire
00:01:16
a pretty calculated forces from the computer to the topic device so for use it's
00:01:20
possible to feel and touch with topics which only the solicitation like bones
00:01:28
uh as an addition we're using all status copy feeding which are with
00:01:33
um i'm hijacking bar mounted on top of them on it or
00:01:36
still it's possible for the user to see three to you without using classes
00:01:41
so um cyprus and then often set aside the material we left in which
00:01:45
the centre left i don't write image sent to the right of user
00:01:50
for the visualisation we're using surface models for the to let the cable and skin
00:01:57
and for the volume uh for the uh for the boulder using one
00:02:01
of the real topographic and segmented volume wells drilled into the bone
00:02:07
you can see a of four images of the drilling
00:02:10
process to k. y. emerge into a bone um
00:02:14
remove several boxes of the bone and afterwards you can check the position of u. k. wire
00:02:20
when you when you would change due to to transparent service model of buttons like an x. ray
00:02:28
we also um used to using a happy fat hand
00:02:32
phantom for up by many unhappy thick so
00:02:35
the rights and you have to drill and only left yeah and you can you can um
00:02:40
top several um points of the hand to find the
00:02:45
right boring or internal where are my restructures
00:02:49
soul for this we want to to print a real three d. hand and attach it to a
00:02:54
to a marker and this markers then be i checked by real time tracking come around
00:02:58
so if you move around happy phantom the visualisation before the movement
00:03:05
um signal we also have a graphical user interface where the user can change um
00:03:11
the tools several came wires and do an extra phone extra bit returns representation
00:03:19
and it's next slides um for better understanding of the chain system appeared at the movie or
00:03:25
see on the left the drilling was a lace visualisation on a pretty much
00:03:29
or and then right i can see me in front of the prototype
00:03:34
start with i guess uh now we can see me i'm moving around perhaps expansion
00:03:41
it's checked by the which object come around and i can adjust the
00:03:45
position and now i pick up the drill a um scum close
00:03:49
to the bone when i'm in contact with the bone i can't feel
00:03:53
forces recalculate forces that uh have been um centred happy device
00:04:00
i can attach to drilling and and now can start a process
00:04:05
i will emerge through the court to card as in the spongy was uh i can
00:04:08
feel it and i could feel um when i um hit the second quarter colours
00:04:15
and when i'm done i can relate to readjust a two track position
00:04:19
and can also removed to do hold and the cave i will remain into the bowl
00:04:27
and after that so i can change my view or i can i
00:04:30
can zoom in first with the over the graphical user interface
00:04:34
and afterwards i can change viewpoints on our can see transparent so for
00:04:39
small thing can check the yeah um cable position in the bone
00:04:48
and it's to conclude my short or i want to introduce you my
00:04:53
whole team of experts origin soften hopper developed by in spite x.
00:04:57
and we are funded from the u. b. f. for them uh the federal ministry of education research
