摘要：
A metering delivery apparatus for injecting bone graft cement includes a body portion, a material containment vessel, an actuator, and a control unit. The body portion includes a drive housing that supports an actuator drivetrain and receiver end that supports the material containment vessel. The actuator has a first end connected to the actuator drivetrain and a second end that supports a moveable portion of the vessel to dispense material in the vessel and a retracting movement that relieves pressure applied to the material. The control unit receives actuator parameter inputs and includes a sensor to detect a signal of at least one of a pressure level and a time period. The sensor provides the detected signal to the control unit such that the control unit operates the actuator between the dispensing and retracting movements based on the detected signal and the actuator parameter inputs.
