Abstract
A hand-held applicator delivers liquid or semi-liquid compositions, such as adhesives, to an internal tissue or organ in an even and controlled manner. The applicator includes a pump, a tubular extension that is thin enough to pass through an endoscopic pathway or trocar, a proximal end of the tubular extension being sealingly connected to the pump, and an applicator tip that attaches to the distal end of the tubular extension. The tip includes the liquid and the pump pumps the liquid to the internal tissue in an even and controlled manner without contact of the liquid by the pump. The pump is preferably a micropipetter that includes a hand-held portion having a hand-actuatable plunger that does not come in direct, physical contact with the liquid to be dispensed. The composition may be an adhesive such as an alpha-cyanoacrylate. The device may further include a wound closure device including at least two closure pins extending from the distal end of the tubular extension. The wound closure device retracts from the applicator device and orients and aligns a wound or incision target tissue site immediately prior to application of the medical composition. The device provides improved control, ergonomics, and convenience. The device is particularly useful in the field of surgery, especially in the field of laparoscopic or endoscopic surgery, where an even and controlled amount of a medically-acceptable adhesive is to be applied to a target site on an internal tissue or organ.
