Definitions
- the present disclosure relates to surgical instruments and methods for enhancing properties of tissue repaired or joined by surgical staples and, more particularly to surgical instruments and methods designed to apply and confine a non-mechanical biocompatible wound closure material to enhance the properties of repaired or adjoined tissue at a target surgical site.
- suturing was the accepted technique for rejoining severed tissues and closing wounds.
- Suturing was historically achieved with a surgical needle and a suturing thread, and more recently, with a variety of polymeric or metallic staples, as will be discussed below.
- the intended function of sutures is to hold the edges of a wound or tissue against one another during the healing process so as to reduce discomfort, pain, scarring and the time required for healing.
- Staples have recently been used to replace suturing when joining or anastomosing various body structures, such as, for example, the bowel or bronchus.
- the surgical stapling devices employed to apply these staples are generally designed to simultaneously cut and seal an extended segment of tissue in a patient, thus vastly reducing the time and risks of such procedures.
- Linear or annular surgical stapling devices are employed by surgeons to sequentially or simultaneously apply one or more linear rows of surgical fasteners, e.g., staples or two-part fasteners, to body tissue for the purpose of joining segments of body tissue together and/or for the creation of anastomosis.
- Linear surgical stapling devices generally include a pair of jaws or finger-like structures between which body tissue to be joined is placed.
- firing bars move longitudinally and contact staple drive members in one of the jaws, and surgical staples are pushed through the body tissue and into/against an anvil in the opposite jaw thereby crimping the staples closed.
- a knife blade may be provided to cut between the rows/lines of staples.
- Examples of such linear surgical stapling devices are Models "GIATM” and “Endo GIATM” instruments available from United States Surgical, a Division of Tyco Health-Care Group, LP, Norwalk, CT and disclosed in, inter alia, U.S. Patent No. 5,465,896 to Allen et al., the entire contents of which is incorporated herein by reference.

- an external means 200 such as a syringe
- a method of the present disclosure may be implemented after an anastomosis procedure where a body organ, such as an intestine, bronchus or bowel, is surgically stapled using an end-to-end anastomosis stapler or other suitable device.
- a body organ such as an intestine, bronchus or bowel
- an end-to-end anastomosis stapler or other suitable device After such a procedure, the end effector 24 of the apparatus 10 is positioned near the staple line of the tissue, with the end effector 24 in an open position.
- the user then closes the end effector 24 around the body organ 36 by actuating the end effector operating means 14 of the apparatus 10. After the end effector 24 is closed, the user applies the sealant 34 to the desired tissue by actuating the sealant- applying structure 16.
- the end effector 24 is maintained in a closed position until the sealant 34 has sufficiently cured. After sufficient curing has taken place, the user may open the end effector 24 by actuating operating means 14 and removing the apparatus 10 from the patient's body.
- an applicator clamp 110 may be provided for surrounding a body organ 136 or tissue and for applying sealant 34 thereto.
- a user places the applicator clamp 110 around the body organ 136 and closes the applicator clamp 110.
- the user then may use a sealant applicator device 144 and/or an external means 200 to apply the sealant 34 to the tissue.
- the sealant applicator device 144 disposed on the applicator clamp 110 can include a switch, button, slide or the like to release biological sealant from within the applicator clamp 110, through openings within the applicator clamp 110, and onto the tissue.
- External means 200 such as a syringe, can be used to inject the applicator clamp 110 with a biological sealant solution that would be applied to the tissue through openings within the applicator clamp 110.
- Side walls may be disposed on the jaw members 128, 130 to confine the sealant 34 to the desired location.
- the end effector 24 may be configured to apply sealant 34 to a surgical site that has been linearly stapled.
- extraluminal sealant applicators and method of the present disclosure may be utilized in a number of other applications and is not limited solely to bowel, intestine or bronchus anastomosis.
- a sensor to detect when the sealant has sufficiently cured, and thus when the surgeon should remove the apparatus.
- pins disposed on the edges of the side walls penetrate the outer skin of the body organ, but do not penetrate beyond the outer skin.
- an adhesive can be applied to the anastomosis site, in lieu of, or in addition to the sealant.
- each of the extraluminal sealant applicators described herein may be used following surgery performed with an annular surgical anastomosing device, which is capable of approximating, adhering and cutting tissue.
