The problem of or table control handle

The most likely to fail in an electric or table is the control handle, because of 2 tips: 1. The line connecting control handle; 2. The mechanical keys on the handle are easily damaged. For problem 1, basically all the connection line will have this problem. From C-arm foot to monitor leads, none can survive. Many medical operation table manufacturers have put some effort into the design of the net, and their life can be slightly longer, but the range of disconnection extends to the junction of the net and the line, so I don't think it has solved the problem fundamentally. My suggestion is that it can be designed as split design, wireless cable, by wireless communication, let the handle get out of the operating bed.

For problem 2, there are restrictions on the use of mechanical keys. When the upper limit is exceeded, the mechanical structure has changed, which has led to the implementation of the keys and the control failure. This type of problem can be referenced to the electromagnetic oven's touch, capacitive or proximity switch type, but to do a good job locking, careful touch.
