Not a joke, really.

I've been quietly listening to the list for a while, and indeed this 
is the right place to ask this question.

I work as medical director for mountain and cave rescue teams, and we 
try to plan ahead for even unlikely occurrences -- such as a caver 
with a leg trapped under a rock.

Don't worry about anaesthesia, bleeding control, etc.  And don't 
worry about the skin and soft tissues -- cutting through them with a 
serrated pocket knife is fine.

The problem is cutting through the big bone in the middle, in cramped 
spaces.  In the operating room under controlled circumstances, we use 
a wire saw like those sold in camping stores (about 14" long with 
serrations along it, a split ring on either end).  Actually, one of 
the orthopedic surgeons in Charlotte, NC has switched to actual 
camping saws -- they're a lot cheaper and work just as well.

But one of these saws requires a fair bit of room around the leg, and 
might not work very well in some situations.  An alternative is a 
Gerber folding camp saw, which can be used with minimal motion even 
in a confined space. But it still requires some motion, and in some 
situations might be very slow and tiring to use.

I had seen a "WoodZig" at the local Hechinger's last year -- a tiny
battery-powered chainsaw (blade about 6" long) on a long stick, for
tree pruning.  But Hechinger was out of them.  And when I called up
the company in Portland, OR, they said they had discontinued them
and had nothing similar to offer.  Gak.  It had looked ideal -- just
hold it in place and it would cut right through. 

Any of the inventive minds on this list seen anything else that would 
be good?  The requirements are:

1. lasts long enough to cut through a leg
2. can adapt to using non-rechargable batteries (don't trust NiCads 
for rare, life-safety situations)
3. lightweight for hauling into wherever
4. can be easily used in very tight situations where one can just 
reach in with one hand.

Thanks for any suggestions.
