Estimating the term…
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.

A mixer for mixing particles and liquid to form an orthopaedic paste comprising a storage chamber having a cap detachably connected to one end of the chamber;
A perforated balloon for entrapping an orthopaedic paste in a bone cavity until the paste is hardened in a bone cavity, wherein the perforated balloon is adapted to be mounted on an end of a tube of an orthopaedic paste delivering tool through which the paste is injected into the balloon, wherein the perforated balloon comprises a first type of perforations, and the first type of perforations comprise a patterned perforation array which cause the rupture of the balloon when the balloon is dilated and is subjected to an exterior force.
A non-inflated tool for expanding a bone cavity in which an orthopaedic paste is to be implanted comprising a flexible linear filler and a rod with one end thereof connected to one end of the flexible linear filler, so that the flexible linear filler can be pushed by the rod through a tube into a hole of a bone to expand a bone cavity in the bone
A surgical tube comprising a means at a front end thereof for preventing blood/body fluid from entering the surgical tube, and said means is able to be open or broken by a force exerted thereon.
