Abstract

Apparatus and methods are provided to remove biopsy specimens from a bone and/or associated bone marrow using a powered drive and an intraosseous (IO) needle set. The powered driver may rotate the IO needle set at an optimum speed to obtain a biopsy sample of bone and/or bone marrow. Apparatus and methods may also be provided for aspiration of bone marrow and/or stem cell transplant procedures. The apparatus may include a powered driver, a coupler assembly, a containment bag or sterile sleeve and various IO needles and IO needle sets with associated hubs and/or hub assemblies. Each IO needle set may include a cannula or catheter and an associated trocar stylet with respective tips operable to penetrate a bone and/or bone marrow with minimum trauma to a patient. Each hub assembly may be used to releasably dispose a respective stylet within an associated generally hollow cannula. Some coupler assemblies and/or hub assemblies may also be used with manual drivers.

Claims20

Dependent claims

A coupler assembly operable to releasably engage one end of a drive shaft extending from a powered driver with an intraosseous (IO) device having a first end operable to penetrate a bone and associated bone marrow, the coupler assembly having a first end and a second end, the coupler assembly comprising:

an elongated core having a first end operable to be releasably engaged with a second end of the IO device;
the elongated core having a second end operable to be releasably engaged with the one end of the drive shaft extending from the powered driver;
a housing assembly having a first end and a second end with respective openings formed in the first end and the second end of the housing assembly;
the openings in the first end and the second end of the housing assembly each having dimensions and configurations selected to be compatible with exterior portions of the elongated core disposed within the housing assembly;
a biasing mechanism disposed between an interior shoulder of the housing assembly and an exterior shoulder of the elongated core, where the biasing mechanism is operable to bias a first portion of the housing assembly and a second portion of the housing assembly to a first position, where the first end of the housing assembly is closer to the first end of the elongated core when the first portion of the housing assembly is in the first position than in a second position, and where the second end of the housing assembly is closer to the second end of the elongated core when the second portion of the housing assembly is in the first position than in the second position;
a first receptacle disposed in the first end of the elongated core at a location corresponding with the first end of the coupler assembly;
and
a second receptacle disposed in the second end of the elongated core at a location corresponding with the second end of the coupler assembly,
where the first portion of the housing assembly is configured to slide along a longitudinal length of the core between the first position and the second position,
where the second portion of the housing assembly is configured to slide along a longitudinal length of the core between the first position and the second position,
where the second portion of the housing assembly is configured to slide over the elongated core relative to the first portion of the housing assembly, and
where the first end of the elongated core has an outer diameter that is greater than an outer diameter of the second end of the elongated core.
