Abstract

A medical agent dispensing system and surgical instruments that employ the medical agent dispensing system are provided. The dispensing system may be structured for use with a surgical severing / stapling instrument structured for severing and stapling tissue. The dispensing system may include at least one storage reservoir structured for storing at least a component of a medical agent and a pump in communication with the storage reservoir; a delivery tube in communication with the pump which is structured to receive a quantity of the medical agent from the storage reservoir during operation of the pump; and, at least one agent tube in communication with the delivery tube which is structured for communication with a least one agent port formed in a staple cartridge or an anvil of the surgical instrument for dispensing the medical agent therethrough.

Description

technical field [0001] The present invention relates generally to surgical instruments. More particularly, the present invention relates to the delivery and application of medical agents in connection with the use of surgical instruments to promote closure and healing of cut and stapled tissue. Background technique [0002] Conventional surgical staplers that can be used to simultaneously make an incision in tissue and apply suture to opposite sides of the incision are known in the art. Such instruments typically include a pair of cooperating jaw members that are capable of passing through a cannula channel when used in endoscopic or laparoscopic applications. One of the jaw members typically houses a staple cartridge having at least two laterally spaced rows of staples. The other jaw member defines an anvil having staple-forming slots correspondingly aligned with the rows of staples in the staple cartridge. Such a stapling instrument may also include a plurality of recip...
