Abstract
A chemical dispensing system for dispensing a liquid chemical agent, such as an antibiotic, anesthetic, growth factor, hormone, anti=neoplastic agent, or the like, onto or into a site of a surgical procedure. The system includes at least one bladder having an internal cavity that connects to an open tube wherethrough the liquid chemical agent is passed, under pressure, into the bladder. The liquid chemical agent passes, as a low volume flow, through at least one hole formed through a bladder wall and onto the surgical procedure site. Embodiments of the invention include one or a pair of individual bladders formed from a thin flexible biocompatible material, each for positioning in close proximity to a prepared bone surface with a plurality of holes formed through the bladder surface that is in engagement with the prepared bone surface to bleed a low volume flow of a chemical agent onto the bone surface; a bladder for fitting into and to travel along a longitudinal passage of an intramedullary rod or nail to a location therealong that is adjacent to the surgical procedure site for delivering a volume of the liquid chemical agent onto that site; and a fixation device that includes at least one hollow pin for passing a volume of the liquid chemical agent therethrough directly into or onto a bone proximate to a fracture therein.
