BONE CEMENT MIXING AND DELIVERY DEVICE WITH RELEASABLE MIXING BLADE |
摘要 |
A bone cement mixing and delivery assembly is disclosed for mixing a powdered copolymer and a liquid monomer to form a bone cement and deliver the bone cement. The assembly includes a cartridge having a distal end and a proximal end and defining a mixing chamber between the distal end and the proximal end. A transfer mechanism having a cap and a stem supporting a piston and a plunger is connected to the distal end. The transfer mechanism includes a first advancement mechanism for advancing the piston and plunger in unison and a second advancement mechanism for moving the plunger independent of the piston. The assembly further includes a removable handle and a mixing blade releasably coupled to the handle to mix the components of the bone cement. A quick-release connector and a release device are used to lock and unlock the mixing blade from the removable handle.
