An
arthroscope is basically a cylinder with a lens at each end
The light is shone down the arthroscope in the same direction as the
surgeon is viewing in order to illuminate the interior of the
joint
|
 |
| The
buttons on the camera can adjust the amount of light.
We can also
"snap" photos and with some capture videos. |
 |
| The
interior of the joint is seen on a television monitor |
 |
| In
the shoulder the 'scope is often passed down small
"tubes" called portals. This way the 'scope can be
moved from one portal to another in order to visualize the
shoulder from many angles. |
 |
| In
a shoulder arthroscopic procedure we typically use 3 portals.
One for the arthroscope and two for instruments. |
 |
| The
TV is connected to the camera via a machine which processes
the image. The video "stack" also includes a light
source, a photo printer and a video cassette recorder.
Our new 'stack' on the
right have LCD screens, is computer controlled and can save
still pictures and video which can then be burnt onto a CD. |
