A remotely-activated injection device for use in vertebroplasty is provided to inject a flourescent probe material into a patient. The injection device includes a pump defining an injection chamber having an exit opening; an actuator; and a cable having a first end coupled to the actuator, and a second end remotely engaging the pump. The actuator remotely controls the pump by responsive movement of the cable to thereby cause injection of a flourescent probe material from the injection chamber of the pump through the exit opening to the patient.
1. A handheld pumping system comprising: an actuator;a hydraulic piston driver;a housing operatively connecting the actuator to the hydraulic piston driver;a pump defining an injection chamber having an exit opening connectable to a bone needle, the injection chamber containing bone cement and inclu
1. A handheld pumping system comprising: an actuator;a hydraulic piston driver;a housing operatively connecting the actuator to the hydraulic piston driver;a pump defining an injection chamber having an exit opening connectable to a bone needle, the injection chamber containing bone cement and including a piston operatively connected to the hydraulic piston driver so that actuation of the actuator results in the receiving of pressurized fluid by the hydraulic piston driver to selectively actuate the hydraulic piston driver to drive the piston to force said bone cement from the injection chamber through the exit opening;a cement pressure relief device on the handheld pumping system for minimizing contact between pressurized cement and other tissue. 2. The system of claim 1, further comprising a handheld base supporting the actuator for the hydraulic driver. 3. The system of claim 2, further comprising a lever portion pivotally coupled to the handheld base for selectively actuating the hydraulic driver. 4. The system of claim 3, wherein the housing is semi-rigid and connects to the handheld base and the hydraulic driver is actuated through the semi-rigid housing. 5. A handheld pumping system comprising: a hydraulic fluid for pressurization;a chamber containing the hydraulic fluid;an actuator for applying pressure to the hydraulic fluid;a housing connecting the actuator to the chamber containing the hydraulic fluid;a container of bone cement connected to said housing and receiving pressurized fluid to selectively force said bone cement from said container;a pump defining an injection chamber having an exit opening connectable to a bone needle, the injection chamber containing bone cement and including a piston operatively connected to a hydraulic piston driver so that actuation of the actuator results in the receiving of pressurized fluid by the hydraulic piston driver to selectively actuate the hydraulic piston driver to drive the piston to force said bone cement from the injection chamber through the exit opening;a cement pressure relief device on the handheld pumping system for minimizing contact between pressurized cement and other tissue. 6. The system of claim 5, further comprising a handheld base supporting the actuator for the hydraulic driver. 7. The system of claim 6, further comprising a lever portion pivotally coupled to the handheld base for selectively actuating the hydraulic driver. 8. The system of claim 7, wherein the housing is semi-rigid and connects to the handheld base and the hydraulic driver is actuated through the semi-rigid housing.
