How would you keep the lens clear? How would you inflate the colon with water or air so you could see something? How would you point the camera?
@moliere
Thank you for your reply. I think all the problems you point out are quite easy to solve.
1. The camera does not need to stick out, it can be 1/2cm inside te colon snake. Assuming the colon is fully cleaned out nothimng should obstruct the lens.
2. Very easy to solve, no need of a second channel. In the very same channel is enough to insert a small tiny cahtheter. Such catheter does not need to run through the whole colon snake length, but just to be inserted in it. The other end of the catheter stick out of the rear end of the snake and it is attcahed to a small rubber pump (the very same that are used for hold blood pressure devices). The rear end of the colon snake need to be sealed. This is how you inflate air into the colon. Prcatically the camera cable and the small catheter are bot inserted into the colon snake and they run in parallel, but only the camera for the whole snake length. The rear end of the snake is sealed, the front end is not.
3. You cannot point the camera, you are right. However the colon tube has a certain diameter and plus you can inflate air in the colon, so I assume that you should have enough space between the camera lens and the colon walls to be able to see enough. The colon tube can progress into the colon without need of pointing and controlling its front end. Just a lot of lube, pushing and pulling should be enough to insert it all.
4. The camera comes with LED lights :-) so, no need of any additional light source.
Please, let m eknow what you think and whether you know if anybody has ever tried this!
I can tell you that I tried, but not with a colon snake. I tried with much tiny tube. The insertion worked, though it was not really easy, but I couldn't see much because the camera was constantly touching the colon wall. I assume the colon snake, given its larger diameter, should progress easily and push the colon walls far enough to allow a decent view.
