I am wondering if it is time, as a precautionary investment to
reduce the risk of injury, to get something better.

The Rolls Royce solution might be something like the 10 ft
version of this:

A tripod ladder is a bad idea, as they are a lot less stable than
a corresponding quadrupod one. We bought an industrial-grade one
from Mackays at 150 quid (versus 50 quid for the 'domestic') and
have not regretted it.

Can you explain why tree surgeons almost always have a tripod ladder?

They have a very wide area of footing and 3 legs is inherently stable on
unplanar ground.
