A fibrin injection mechanism for use in combination with an anastomosing and stapling attachment for an electromechanical device driver comprises a cylindrical dispensing chamber adjacent the cylindrical blade of the attachment and containing a sac filled with fibrin, a plurality of channels extending within the blade communicating between the dispensing chamber and the cutting edge of the blade, such that when the turning drive shaft is activated, the staple driver of the attachment moves forward to push a plurality of staples through corresponding staple ports and against the anvil of the attachment to pass through and staple together the target tissue, while the blade driver of the attachment moves forward to cut the unwanted residual tissue (post stapling), while a plunger (delivery) driver moves forward through the dispensing chamber to compress the sac to its break point, releasing the fluid medication into the dispensing chamber, and eventually pushing the medication though the channels to deliver the fibrin to the cutting edge of the blade and thus to the site of the newly stapled target tissue to accelerate the healing process.
1. A fluid delivery device, comprising:a dispensing chamber containing a fluid; a channel communicating between a treatment site and said dispensing chamber; a delivery driver traveling within said dispensing chamber with a force equal to or greater than the force needed to push said fluid through s
1. A fluid delivery device, comprising:a dispensing chamber containing a fluid; a channel communicating between a treatment site and said dispensing chamber; a delivery driver traveling within said dispensing chamber with a force equal to or greater than the force needed to push said fluid through said channel; and a sac within said dispensing chamber and enclosing said fluid; and wherein said delivery driver is traveling with a force equal to or greater than the force needed to compress and break said sac within said dispensing chamber.
