If your input is always that regular, then a simple cut command will do the job
cut -d/ -f6
eg
% echo /sys/bus/pci/devices/0000:07:00.0/device:0x017a | cut -d/ -f6
0000:07:00.0
% echo /sys/bus/pci/devices/0000:08:00.0/device:0x0abc | cut -d/ -f6

If the Input has not a fix number of /, you may also use grep with context:
$ ... | grep -Po 'devices/K.*?(?=/device)'
