Abstract
Penetrator assemblies that include an outer penetrator and a removable inner trocar. In some of the penetrator assemblies, the removable inner trocar has a handle including a surface with a series of discs formed along a longitudinal axis, and the outer penetrator has a flange operable to engage an insertion site proximate the bone marrow. Some of the penetrator assemblies include a connector having a recess extending toward the cutting tip and through which a longitudinal axis of the outer penetrator extends, the recess configured to receive a portion of a shaft to enable rotation of the penetrator assembly by a powered apparatus or power drill.
Claims15
A penetrator assembly operable to provide access to a bone marrow comprising:
- an outer penetrator and a removable inner trocar including a cutting tip operable to penetrate the bone marrow;
- a first connector operable to releasably attach the penetrator assembly to a powered apparatus;
- the removable inner trocar having a handle;
- the handle including a surface with a series of discs formed along a longitudinal axis of the removable inner trocar that allows a user to grasp and manipulate the removable inner trocar;
- the outer penetrator having a second connector operable to releasably engage the removable inner trocar with the outer penetrator;
- and
- the outer penetrator having a flange operable to engage an insertion site proximate the bone marrow.
A penetrator assembly operable to provide access to bone marrow of a bone comprising:
- an outer penetrator and a removable inner trocar including a cutting tip operable to penetrate the bone and the associated bone marrow;
- and
- a first connector operable to releasably attach the penetrator assembly to a powered apparatus, a proximal end of the first connector having a recess extending toward the cutting tip and through which a longitudinal axis of the outer penetrator extends, the recess configured to receive a portion of a shaft to enable rotation of the penetrator assembly by the powered apparatus;
- the first connector further comprising a magnetic disc configured to magnetically resist removal of the shaft from the recess.
