AVITUS ORTHOPAEDICS, INC. BH8 Avitus Bone Harvester

A manual surgical instrument that cuts cancellous bone by manual actuation of the8mm cutting tip. The cap contains a barbed nozzle that connects to standard sized suction tubing (tube with an IDof 6–10 mm) to connect to a vacuum source, wherein the vacuum source has a static maximum pressurebetween 150 mmHg and 300 mmHg. The proposed device can be connected to a waste canister that leads tostandard operating room wall suction or to an external pump. With the device connected to a vacuumsource, when actuated in bone the cutting tip carves, scrapes and cuts cancellous bone and collects the bonegraft inside the handle. The suction pulls the bone and bone marrow from the cutting tip and into the bonereservoir inside the handle. The cap contains a filter that prevents material from escaping the handle into thesuction system by utilizing a physical sieve to keep bone particulate in the handle. After harvesting, the bonegraft can be retrieved from the handle.
