Percutaneous bone graft delivery system

摘要

A bone graft delivery system includes a bone graft injector and an access portal. The access portal may include a handle (200) having a first arm pivotably connected to, and biased away from, a second arm. A ratchet including a pawl may extend from the second arm. A delivery tube (500) may be configured to mate with the first arm and be configured to store a bone graft material therein. A plunger (400) including a shaft and a plunger tip at the distal end thereof may be configured to move through the delivery tube. At least a portion of the shaft may include teeth, the pawl of the ratchet being configured to iteratively contact the teeth. A user may hold the access portal with a first hand and the bone graft injector with a second hand, iteratively squeezing the handle to iteratively eject amounts of bone graft material into a patient.
