BACKGROUND
Modern surgical techniques oftentimes employ the use of specialized drills and bits to create holes in bone for the attachment of various devices such as pins or bolts for bone plates. In order to prevent thermal bone damage induced from drill friction, saline solution is dripped onto the surface of the bone. However, this only serves to cool a very shallow depth of the bone, resulting in damage still being done deeper in the osseus tissue. There is a need for improved cooling in bone drills for surgical procedures.
SUMMARY OF TECHNOLOGY
Researchers at OSU have conceived of a novel bone drill and bit for surgical approaches. This drill is a handheld device instead of a mounted device (current equipment standard) providing greater control to the surgeon. The novel bit is designed to provide irrigation at the bit, which will provide two distinct advantages. Primarily the pressurized saline irrigation will reduce thermal damage to bone, allowing for faster healing and a reduced chance of implant failure. Additionally, the saline being pumped from the bit will improve bone chip clearance, reducing friction and keeping the bore hole cleaner. This technology will increase not only the rate at which post-surgical healing can occur, but it will also reduce implant failure due to damaged bone.
