DEVICE FOR FORMING A HARDENED CEMENT IN A BONE CAVITY

摘要

A device for injecting a cement paste into a bone cavity and forming a hardened cement in-situ under pressure includes a syringe having an injection end; a pocket having an inlet and a body for containing the paste entering the inlet; and a mounting mechanism at the injection end for connecting the inlet of the pocket to the injection end so that the body of the pocket can contain the paste through the syringe. The device further includes a leaking mechanism provided on the body of the pocket or provided at the injection end of the syringe for allowing liquid contained in the paste inside the pocket to be expelled from the pocket under pressure, and an opening mechanism which can be operated at a location away from the injection end to open the body of the pocket.
