I used to write a script in Macro/Keybind Mod that allows to jump using mouse wheel up. It works, but the mouse wheel can still be used to change the hotbar slot. In «controls» I didn't find option to disable it. How I can do it?

Here are some more mouse-trap applications, like CSMMT which Shaun's answer mentioned, that trap your mouse cursor in one screen of a multi-monitor setup:
- MouseTrap
- MouseJail
- MurGeeMon (supports Lock Mouse Cursor On a Monitor)
- Script for AutoHotkey
I can't vouch for any of these, but you can try them out. You can also search for more with keywords "multi monitor trap mouse" or similar.
I'm not aware of a way to remap the scroll wheel within Minecraft, so I think your best bet is to look for third-party tools that will remap your mouse keys for you. After a quick Google search, I found X-Mouse Button Control for Windows, and USB Overdrive for Mac.
Looking at screenshots of both programs, they both allow you to remap mouse buttons as mouse wheel up {MWUP} and mouse wheel down {MWDN}, which is perfect for item-switching in Minecraft.

I’m not sure if this is an actual option, but here:
In settings, there is a hotbar up/down selection with “MW UP” and “MW DOWN”. Remove these or set them to another key, like “period” or “left bracket”.
