Hinami's father is pure filler. He died before the manga even began (at least 2 months before it started, since Mado already had her father as a Quinque in his first appearance, though the actual reveal isn't shown till later, and it takes around 2 months for even a simple quinque to be processed). Since the anime didn't talk about RC or RC suppressants, they instead had Jason use a pair of pliers made out of quinque steel, which in the filler Hinami's father knew how to make a bootleg version of.

In the actual canon material, they were just normal autopsy/surgery tools, and RC suppressants were injected into Kaneki's eye through the mucous membrane which is the only part of a ghouls body that cannot harden up.
