Abstract
The present invention discloses a technique for continually delivering an orthopaedic paste into a bone, which will harden in the bone and act as a medical implant. The present invention uses a replacement mechanism in delivering the paste stored in a chamber through a tube in fluid communication with the chamber, which includes invading the paste in the chamber with a small volume of recovery member such as a rod to replace the same volume of paste into the tube, and retreating the invading rod while applying a pressure to the paste in the chamber, so that a space created by the retreating is replaced by the paste, and repeating the invasion and the retreating alternately to continually deliver the paste through the tube.
