Thanks for all the help, everyone. So far I have 2 ideas, run with them
if you'd like for your situation, or comment as well.
Periscope Idea, DIY
-Except only 1 turn, creates problem of magnification and orientation
(mirror reverses image)
-Solution, create tube with several (odd in number) convex lenses, and a
mirror at 45 degrees at the top over the specimen.
-Will magnify and allow work in a neutral posture (working at elbow
height with hands and eyes looking forward to the mirror.
-project image pf specimen on a screen at eye level.
Both are simple add-ons that allow the inking, sectioning, etc. to be
performed on a horizontal surface but also reduce the risk of neck and
Currently looking into building the "periscope." BTW does anyone know
if this thing has a name besides calling it a modified microscope.

Possibly an angled mirror over the specimen? Bottom edge of the mirror
in contact with the benchtop, behind the specimen; mirror leaning toward
the tech at a suitable angle? This would give the tech a perpendicular
view of the specimen with a normal angle of view for the tech.

> The Problem:
> When techs at UNC perform grossing, they often lean (while standing or
> seated) with their head into the fume hood/bio safety cabinet to get a
> top down view of the biopsies and excisions (performing inking,
> describing markers, and slicing samples). This posture poses a
> significant risk of injury on the back and neck thus the need for a
> workstation adjustment. The risk of inhalation is low, but present,
> so that is a minor concern as well.
> Initial Thoughts:
> 1. Rotate the sample to face the histologist, like reading a book.
> 2. Affix the sample to a cutting board (or the surface currently in
> use) by means of a reverse action tweezers mounted to the board.
> 3. At this angle the histotech can see the sample with minimal neck
> bending (while keeping the head out of the hood) as well as reduce the
> need to hold the sample while performing inking, etc.
> 1. Has anyone tried this?
> 2. Does anyone else have a solution that would work in this
> 3. What is your opinion on this solution?
> Any ideas or comments are greatly welcome.
> Thank you!
