Slip-fit handle for hand-held instruments that access interior body regions

摘要

A cannula instrument is deployed in soft tissue to form a percutaneous access path to bone. A guide pin instrument is sized and configured for passage through a bore of the cannula instrument. A handle separate from the cannula instrument and the guide pin instrument includes an attachment component configured to selectively engage or disengage the handle attachment site of the cannula instrument to aid in advancement of the cannula instrument through soft tissue and form the percutaneous access path. A passageway in the handle accommodates passage of the guide pin instrument through the handle to accommodate sliding the handle over and relative to the guide pin instrument when selectively engaging or disengaging the attachment component and the handle attachment site. A therapeutic instrument is deployed through the percutaneous access path.
