INSTRUMENT FOR DEBRIDING FISTULA AND APPLYING THERAPEUTIC CELLS

摘要

A treatment instrument comprises an end effector (1010) and a plunger (1020). The end effector comprises a plurality of cutting features and an interior cavity. At least a portion of the plunger is slidably positioned within the interior cavity of the end effector. The plunger comprises a distal head (1022) attached to the distal end of a central shaft. The plunger (1220) is configured to rotate within the end effector, and comprises a cutting member (1228) that is operable to mince tissue specimens captured by the cutting features of the end effector. An alternative treatment system comprises an end effector (1310), a plunger (1320), and a plug (1350). The central shaft (1324) of the plunger and the plug are slidably located within an inner tube of the end effector, with the plug being positioned distal to the central shaft.
