How Does Robotic Surgery Work? | Dr. Jagannath Dixit | Manipal Hospital Yelahanka
Watch on YouTubeVideo summary
Dr. Jagannath Dixit introduces the DaVinci Xi system as the latest fourth-generation robotic surgical technology available in India, highlighting its three primary components: the patient cart, the vision cart, and the surgeon console. The patient cart features four slender universal arms, including a camera arm and three working instruments, which are mounted using an innovative vertical boom that allows for nearly 180-degree rotation. This unique design prevents the arms from colliding with each other and provides a clearance of 45 degrees, ensuring smooth operation even in tight spaces. The camera itself offers binocular vision with a range of motion extending 30 degrees up and down, equipped with halogen bulbs and telescopes to provide high-quality illumination and imaging during procedures.
The vision cart serves as the central hub for monitoring and controlling the robotic arms, featuring a touch screen module that displays real-time data on all four instruments. It allows surgeons to adjust camera angles, mark or erase annotations, and view usage statistics, while also housing a high-end DaVinci E200 generator with various energy sockets for surgical tools. A key feature of this system is the fiber optic light source that delivers bright illumination directly into the surgical site. The console connects to these components via ergonomic interfaces, enabling precise control over instrument movements and energy settings, which are essential for complex minimally invasive surgeries.
At the surgeon console, the doctor sits in a comfortable, ergonomically designed position that mimics natural hand movements, allowing for intuitive control of the robotic arms through master-slave technology. The system translates the surgeon's hand motions with varying ratios—ranging from 1.5:1 to 3:1—to enhance precision, particularly in confined areas where fine adjustments are critical. Controls include pedals for shifting and braking, as well as hand controls that offer different modes such as quick, normal, and fine, alongside advanced features like digital zoom, haptic feedback, and Firefly technology for enhanced visualization using indocyanine green (ICG) imaging.
The robotic instruments replicate the full range of human wrist movements, including rotation, flexion, extension, and circumduction, with sharp scissors and bipolar tools that offer superior dexterity compared to traditional laparoscopic equipment. The surgeon wears an earpiece for direct communication and relies on a high-definition 3D display offering 10x magnification to navigate the surgical field with exceptional clarity. By integrating these advanced technologies, the DaVinci Xi system enables surgeons to perform intricate procedures with greater accuracy, safety, and efficiency, ultimately improving patient outcomes through minimally invasive techniques.

Hi dear friends, I'm Dr. Jagannath
Dixit. I'm a surgical oncologist, lead
consultant working at Manipal Hospital
in Lanka. So today, you know, we are
going to unique unique gadget called
DaVinci Xi
instrument. This is the latest available
technology in India and it is the fourth
generation, you know, technology. So the
unique component of robotic as such, you
know, has got a three important
components. One what we call is the
patient cart. On my right side is called
the vision cart. And also on the corner
there you can see the surgeon console.
So [music] these are the three
components of the robotic DaVinci
component. So coming to you know here,
you can see that you know these are all
universal arms
>> [music]
>> and you know there are four arms. One
camera comes and another two arms are
the working and the other one is the the
third arm. So these arms are very
slender.
And their unique is that of the Xi
component is that the boom comes
vertically and it makes a almost a 180°
angle rotation. That is a unique part of
that. You know, this docking [music] can
happen next to the patient or it can
come from the other side also. So coming
to you know this important component,
since the boom rotates almost like 180°,
you don't have to worry about the you
know the the clashing of this individual
arms and there is a clearance of
individual arms by 45°. Once you focus
the camera, [music] so this is the
unique component called as a camera
here. You can see that this is a unique
nature and it has got a you know
mentioned here 30°. So this camera you
can make a [music] 30 up and 30 down and
this is what we call switching on the
you know lamp here. Then taking [music]
the still photos is all possible through
this. So this is already written there
is a 30° and another one is a 0° and it
has got a binocular vision
>> [music]
>> and you can see that, you know, here is
the, you know, the component of the two
halogen bulbs comes and with
you know, the two telescopes. [music]
This is a unique feature of the
camera. So, coming to the cannula, these
cannulas are 8 [music] mm. So, it is
easy to put it into the slot. You have
to press it and it
release like that. So, this is [music]
how
So, this is how we mount the cannula. If
you look at the arms, individual arms,
you know, these are all the very fine
arms. You can see that this is a
scissor. This you can see the how the
rotation happens. So, this is how we put
it into the slot. You know, I will show
you this is how we put it into the slot.
So, this
sensors,
they instrument and then, you know, all
arm movements can happen. This is how
the range of movements happens in
different directions. So,
coming to the boom as such, [music] here
you can see that the, you know, boom is
controlled here.
So, this is a power button. So, these
are all the, you know, different
movements you can do. One the boom
position,
you know, then the height of the boom
>> [music]
>> and this is how we drive the car. So,
this is the picture and you can see that
these are all the different settings
which [music] are available. So, coming
to the um
the vision card. Vision card, the unique
nature is that it has got a touch screen
module and where it it will display all
the instruments in each individual arms,
you know, like this, one, two, three and
four. And here you can see that, Uh, you
know, the what
30° up and down and the type of the
camera and even you can mark it here and
also you can erase it. And it will also
shows the number of usage which are
happened in the here in the display. So,
this is what we call vision card and
other additional component of the vision
card you can see that this is energy
source. [music] This is a very unique
high-end available in the world as such
DaVinci E200 generator. It has got two
monopolar socket and two bipolar
sockets. This is the where the neutral
the card comes [music] out. So, this is
where the camera, you know, attachment
comes. This has got a beautiful light
source [music] coming all the way into
the through the fiber optic cable. So,
these settings are available. So, this
is what we call as the
you know, the vision card. So, coming to
here is the corner you can see that this
is the surgeon console. This is the
place where the surgeon sits comfortably
and these are all the ergonomics are at
at rest here only. You know, I can make
the individual adjustment of the you
know, the height and all that. This is
the you know, the connections.
This is a clutch pedal. This is a camera
zoom in, zoom out. This is my bipolar.
You know, right hand and this is my
bipolar on the left hand or unipolar
here and bipolar here. This is the
vessel sealer or the stapling. If it is
coming to right side, it will be the
right or the left. I have [music] to you
press this. And this is a shift pedal
where you can align. And this is where
my fingers [music]
you can see here. It goes like this.
And this is how you know, the movements
happens at the [music] this level. So,
the most important is that my head has
to be placed then you know, this this
movements becomes easier. So, and here
you can see here. So, this hand control
has got [music] three range, one quick,
normal, and fine. So these are all the
thing it moves 1.5:1, [music]
2:1, and 3:1 like that. So whenever you
are doing in a very closed area,
probably fine will be good. And so these
are all the display, the type of haptic
zoom is there, digital zoom is there,
and work distance, then the right eye,
left eye, then this is a tile pro,
and the Firefly technology. ICG mode is
the Firefly. This is a hand control we
have seen. And this is the energy source
which we have seen that you know you can
adjust yourself. And this is a type of
instrument. Now the arm one has got a
monopolar curved scissor. Arm three is
my right hand Maryland bipolar and the
arm two will be the scope. Now I can
[music] put you in ICG mode here and
this is 30 up, 30 down. You can see this
is a energy cord I can do the [music]
settings. So this is the name of the
surgeon you can use be displayed here.
>> [music]
>> And the surgeon and you know
alphabetical order it will be there. If
somebody wants to add account we can use
there here. First name, last name,
[music] and all that. So they can add
that. So these are all the features this
is available. This is a hand [music]
control where you have to insert and
move that. So these two fingers will go
into the sockets here. This is the mid
[music] index finger goes on the clutch
here. So once you put the head like this
and move, it will be translated here. I
can make it this direction. I can go up,
go down, and also circumduction all
around. These are all possible. This is
the scissor you can look at the
sharpness of the scissor. And you know
this is a unique nature. [music] You can
see the bend how much I can do here. And
range of movements and all that. I can
make it this direction or I can [music]
make it this direction. So both the
instruments work together, you know.
They are quite aligned. [music]
So this sharp instrument preferably
right hand, and the left hand will be
the usual deal, our bipolar [music]
source. So, this is the range of
movement which I have got. This is a
very, very beautiful,
ergonomically very good, and almost all
the
human hand, how it rotates, [music] the
instruments makes in the similar
fashion.
>> So, here you can see the inner vision,
and this is [music] my ear piece where,
you know, whenever and the these speaker
phones are here, and whenever I give a
command, it goes directly there. And
this is my, you know, the the once I
place the head, the instrument start
moving. You can show the inner view
here.
So,
that is this is a, you know, 3D 10x
magnification, and you will have a
beautiful immersive view
>> [music]
>> with a 3D background.
So, this is about the surgeon console.
Thank you.
Thanks a lot.
