| 摘要 |
Apparatus and methods for delivering a clotted biological component (such as blood, autologous conditioned plasma (ACP), platelet-rich plasma (PRP), bone marrow aspirate (BMA), demineralized bone matrix, anticoagulants and/or clotting agents, or combination of these materials) into a tissue void (for example, a bone void such as a bone tunnel, socket, opening or cavity), and then cutting the clotted biological component with a cutting or shearing mechanism at the tissue surface. The apparatus is provided with a tube and a cutting or shearing mechanism (provided on or within the distal end of the tube) that is actuated to cut or break off the clot at the desired insertion length. The tube may then be placed over the next tissue void so that the obturator drives the next clot into the next tissue void until all tissue voids are filled. Upon insertion at the defect site, the biological component advances the healing of the damaged tissue and tissue growth.
