摘要：
A tissue treatment device comprises a housing having a chamber that receives a treatment fluid mixture of tissue morsels and a scaffold material. A debriding shaft including a plurality of cutters is coupled with the housing. The debriding shaft extends proximally within the chamber and extends distally from the end of the housing. The debriding shaft is inserted within a treatment site such as a fistula tract and is rotated and reciprocated such that the debriding shaft removes tissue cells along the site. The site is flushed with saline or other irrigating fluid followed by application of the treatment fluid mixture. The chamber of the housing comprises agitators positioned adjacent the debriding shaft. The treatment fluid mixture passes through the chamber of the housing along and between the outer surface of the debriding shaft and the agitators for thorough mixing before exiting the device at the treatment site.
