A fibrin injection mechanism for use in combination with an anastomosing and stapling attachement for an electromechanical device driver comprises a cylindrical dispensing chamber (95) adjacent the cylindrical blade (75) of the attachement and containing a sac (100) filled with fibrin, a plurality of channels extending (90) within the blade (75) communicating between the dispensing chamber (95) and the cutting edge (75) of the blade, such that when the turning drive shaft is activated, the staple driver (65) of the attachment moves forward to push a plurality of staples (60) through corresponding staple ports (55) and against the anvil (20) of the attachment to pass through and staple together the target tissue, while the blade driver (75) of the attachment moves forward to cut the unwanted residual tissue (post stapling), while a plunger (delivery) driver (110) moves forward through the dispensing chamber (95) to compress the sac (100) to its break point, releasing the fluid medication into the dispensing chamber (95), and eventually pushing the medication through the channels (90) to deliver the fibrin to the cutting edge of the blade (75) and thus to the site of the newly stapled target tissue to accelerate the healing process.
