I am sorry to learn of this situation.
With regards ***** ***** employer, you are going to need to pursue your claim through the worker's compensation system (this may include needing to retain a worker's compensation lawyer - which I would highly recommend if you have already received a denial).
The worker's compensation system substitutes for the tort claim system to compensate employees that are injured on the job. In exchange for the strict liability that employees have under the worker's compensation system (if it happens on the job, the employer is liable), the employee is limited to the damages offered under the worker's compensation plan (so you must cooperate with limited work releases, etc.). (I am of course simplifying things, worker's comp is a subspecialty and most attorneys that work in this field do nothing else).
Exceptions to the above would include instances where an employer acts intentionally (but based on what you have posted, it appears that the employer acted negligently - placing it within the worker's comp system).
With the above understanding, that does not mean that you must automatically accept whatever the initial recommendation by the worker's comp evaluator is. This is why you retain a worker's comp attorney to represent you.
Unfortunately, based on where you are in the process (again, based on your post), you are far too advanced in the process to be able to competently proceed without counsel, you really need an attorney to help you salvage this before you inadvertently harm your case beyond recovery. (You likely still can, but do not triffle with the matter, hire an attorney promptly).
You can find local attorneys using the State and local Bar Association directories, or private directories such as www.AVVO.com; www.FindLaw.com; or www.Martindale.com (I personally find www.AVVO.com to be the most user friendly).
You can still sue the patient for his battery on you (once he struck you it changed from an assault to a battery). Whether or not you are going to be able to recover anything from the defendant is another matter (I don't know how financially solvent he is, but you can certainly sue. Both assault and battery are intentional torts and you can recover punitive damages (understand that the circumstances of the battery may affect how much you can recover, as will the fact that you were acting in a healthcare setting which may lead to an argument of "assumption of the risk" which can limit recovery (although they should not eliminate it)). But again, you can sue - just without knowing how solvent the defendant is, I have no way of knowing if this is viable for you or not.
