I am trying to record operations on a GoPro. The lens is fine and I have wired power and HDMI out to a small monitor. My problem is that the Boom on which the overhead GoPro is mounted is not always looking where I am. If the boom comes from the opposite side then it is often 90 degrees out, etc. I know that i can change orientation in FCP but it is not lossless.
I am looking for something i can attach to my carbon fibre boom and which will allow the GoPro to rotate through a 360 degree circle so that wherever the boom comes from I can orientate the GoPro how I want it.
As a stretch if it also had a lighweight X/Y motor to allow staff to move the GoPro that would be fantastic.

Nothing helpful to offer, but *OOOOHing* at exciting surgery recording! That sounds fascinating and really useful for all sorts of things.

You could probably do something with a DJI Osmo. It's essentially the type of gimbal they use in drones, but handheld, so could be boom-mounted.

There are apps which allow you to track action from a moving camera.

Thanks ESL, I had thought about that. I may still buy one just because I want one! That provides stability but that is not my problem as the system is extremely stable with the boom.
I think what I am wanting is a 90degree connector from the boom to a rotating head with another 90 degree connector for the GoPro
Baratka, yes my aim is to produce a library of patient and surgeon teaching videos before I retire covering the majority of Hand Surgery.

Some sort of tripod head? eg a ball head would let you rotate in most directions.
Or a bendable arm? eg GoPro gooseneck. https://shop.gopro.com/EMEA/mounts/gooseneck/ACMFN-001.html
Or a Manfrotto friction arm. https://www.manfrotto.co.uk/photo-variable-friction-arm-with-bracket

Fuaran you are a genius. That gooseneck is the low tech, cheap way to do exactly what I want. Thank you

The Manfrotto Magic Arm is the choice in TV-land. Get the wheel-lock one rather than the cam-locked one, as it's easier to lock - you have to move the cam over it's high point, and this often makes the arm move suddenly, knocking it out of the position you've just set up. The wheel-lock is much smoother. They're good for a couple of kilos at least, and we put all kinds of lights or camera mounts on them.
They'll probably need a fitting to hold the GoPro, as it doesn't come with a tripod screw. We've used the little perspex waterproof housings before now, and put a K-clamp onto the arm, and then we just hold the whole thing in the jaws of the clamp.
For something lighter, Noga (http://www.holditbynoga.com/) also make similar arms which we use for Lilliput monitors. They often come pre-fitted with tripod (1/4"x20) or mic stand (3/8x16) screws, and will easily take a GoPro.

I was mainly answering this part of your question.
As a stretch if it also had a lighweight X/Y motor to allow staff to move the GoPro that would be fantastic.
The DJI Osmo and a tablet running the app I suggested would fulfil your requirement.
