Abstract
A surgical kit for inserting a biological material into a portion of the skeletal bone by a minimally invasive technique has several components which are manually operated using a universal tool. The kit includes a docking needle used as a guide for placing a cannula in a bone. The tool has a spring loaded hinged connection for temporarily attaching to the other components and which locks upon release of compression. An ultrasonic probe is inserted through the cannula for forming a cavity within the soft tissue of the bone. Treatment or support material is placed in the cannula and a plunger is inserted in the cannula. The universal tool is connected to the plunger and the material is expelled by telescopic movement of the plunger.
Claims14
A system for performing surgical procedures using ultrasound comprising a control unit having an output, said control unit having a central processing unit, a memory, a visual display and an input device, said probe adapted for insertion through a cannula into a surgical field, said probe having a leading end and a trailing end with a continuous outer wall, said output of said control unit connected to said trailing end of said probe, multiple lumen extending through said elongated probe from said leading end to said trailing end, an ultrasonic transducer connected to one of said multiple lumen, said output of said control unit adapted to modulate and direct said ultrasonic transducer.
An ultrasonic surgical kit for gaining access to the interior of a skeletal bone by a minimally invasive procedure comprising at least one cannula, an ultrasonic probe having a trailing end and a tip, said cannula having a leading end for penetrating through cancellous bone within a body and a trailing end, said ultrasonic probe of a size to telescope through said cannula from said trailing end through said leading end, said probe having an exposed vibrating tip adapted to form a cavity in soft tissue within the bone.
A method of using an ultrasound surgical system comprising the steps of providing an ultrasonic transducer connected to an ultrasonic probe, providing a cannula, inserting said cannula into a skeletal bone of a patient, inserting said ultrasonic probe through said cannula into said bone, activating said ultrasonic probe to form a cavity in said bone, withdrawing said ultrasonic probe, introducing a biological material through said cannula into said cavity, and withdrawing said cannula.
