A hollow drive shaft assembly operable to penetrate a bone and remove bone marrow from the bone for transplantation purposes comprising:

• an outer hollow drive shaft having a first end operable to penetrate the bone and associated bone marrow;
• the outer hollow drive shaft having a second end operable to allow retrieval of bone marrow for transplantation purposes;
• a gear attached to the outer hollow drive shaft;
• the outer hollow drive shaft and attached gear operable to be disposed within a housing and rotated by a motor disposed within the housing;
• the outer hollow drive shaft having an inner channel extending from the first end of the outer hollow drive shaft through the second end of the outer hollow drive shaft;
• the inner channel operable to convey bone marrow from the first end of the outer hollow drive shaft through the second end of the outer hollow drive shaft for transplantation purposes after inserting the hollow drive shaft into the bone and associated bone marrow by the motor coupled with the outer hollow drive shaft;
• a leur lock connector disposed on the second end of the outer hollow drive shaft;
• and
• the leur lock connector operable to connect a suction apparatus to assist in obtaining bone marrow through the inner channel of the outer hollow drive shaft;
• and
• the outer hollow drive shaft having sampling ports operable to obtain portions of the associated bone marrow.

A hollow drive shaft and a trocar operable to penetrate a bone and bone marrow comprising:

• a first gear attached to the hollow drive shaft;
• the first gear operable to be engaged with a second gear attached to a motor to rotate the hollow drive shaft;
• the hollow drive shaft having a first end operable to penetrate the bone and associated bone marrow;
• the hollow drive shaft having a second end operable to retrieve specimens of bone and the bone marrow;
• an inner channel formed in the hollow drive shaft;
• the inner channel of the hollow drive shaft operable to convey specimens of bone and associated bone marrow therethrough;
• a plurality of sampling ports formed in the hollow drive shaft spaced from the first end;
• the sampling ports operable to provide access to the associated bone marrow;
• the trocar operable to be removably inserted the inner channel of the outer hollow drive shaft;
• a sampling port formed in the trocar spaced from a first end of the trocar;
• and
• the sampling port of the trocar operable to be aligned with respective sampling ports of the outer hollow drive shaft to convey portions of the bone marrow to an inner channel disposed within the trocar.
