Abstract
Disclosed herein are intraosseous access devices having various operating mechanisms, as well as methods of the intraosseous access devices. For example, an intraosseous access device includes, in some embodiments, a constant-torque spring assembly, a drive shaft, an intraosseous needle, and an interlock mechanism. The constant-torque spring assembly is disposed in a housing, and the drive shaft extends from the housing. The drive shaft is coupled to the constant-torque spring assembly. The intraosseous needle is coupled to the drive shaft. The intraosseous needle is configured for drilling through bone and providing intraosseous access to a medullary cavity of a patient. The interlock mechanism is configured to prevent rotation of the intraosseous needle and the drilling therewith until the interlock mechanism is disengaged.
