Darth Vader is very well known for his force-choke. It's probably the most specific use of the force that I can remember seeing, in that otherwise you usually see force users pushing or pulling entire people or objects, rather than just part of them.
Why don't the Jedi, or even the Sith, also go for physical force techniques on other parts of the body to incapacitate targets either more quickly, or without killing them?
For instance, a Sith with no qualms about it could squeeze a Jedi's heart and he's dead without having to resort to light-saber fighting. Or force strike their nose up towards the brain. Or probably a lot of other easier and deadlier attacks that simply pull an important vein, causing very quick bleed-out.
A Jedi could do the equivalent of a hard strike to the spine, separating the spine and causing paralysis, but not death. He could disarm his opponents and restrain them.
Why don't force users engage in more varied force attacks, both against other force users and against individuals not fluent in the force?
