Abstract
An apparatus and a method configured for the efficient delivery of a viscous material, such as bone cement, to a surgical site are described. A housing removably receives a large gauge syringe which is filled with the viscous material. The apparatus is a syringe-type assembly that uses at least one vibrating motor together with a plunger rod assembly. The method employs the continuous application of vibrational forces to the central barrel portion of the apparatus during the time that the viscous material is being delivered and/or applied in vivo. The vibration to the central barrel portion increases the tendency of the viscous material to flow thereby making delivery of such materials easier and more efficient.
Claims17
An apparatus for the in vivo delivery of a viscous material, said apparatus comprising:
- an integrated housing having a central longitudinal portion defining a receiver with an outlet and a pair of oppositely disposed, longitudinally extending side portions;
- a syringe comprising a syringe barrel with a front portion which connects with a needle, said barrel received in said receiver and said needle projecting through said outlet, said syringe comprising a plunger assembly received within said barrel and having a plunger rod coaxially slidable within said barrel and a portion of which projects from said housing;
- a plurality of vibrating motors disposed within said housing at said side portions for supplying and focusing vibrational forces on the front portion of the barrel;
- at least one power source electrically connected to at least one of said plurality of vibrating motors;
- and
- at least one switch for activating said plurality of vibrating motors.
An apparatus for the in vivo delivery of a viscous material, said apparatus comprising:
- an integrated housing having a plurality of interior parallel longitudinally extending compartments including a central receiver with an outlet;
- a syringe received in said receiver and removably secured therewith, said syringe having a barrel with a front portion which connects with a needle and a plunger, said barrel entirely received in said central receiver with said needle extending beyond said outlet;
- a vibrating motor received in a compartment and operable at a speed for supplying and focusing vibrational forces at the front portion of the barrel;
- a power source electrically connected to said vibrating motor;
- and
- a switch for activating said vibrating motor.
