ABSTRACT:
A laparo-suture needle and method for use thereof. A medical suturing instrument employs an outer, hollow shaft having a laterally-disposed, elongate handle at a proximal end and an elongate, inner shaft disposed within the outer shaft. The inner shaft has a cutting edge at the distal end and extends out of the outer shaft at the proximal end, terminating in a spring-loaded push button. A lateral notch is formed in the inner shaft proximal of the cutting edge. The spring forces the inner shaft rearwardly so as to pull the notch within the outer shaft. By gripping the handle and placing pressure on the push button, the inner shaft is moved forward so as to expose the notch. A suture may then be placed in the notch so that the instrument grips the suture between the outer shaft and the inner shaft when the push button is released. The instrument is used for suturing muscle at an incision by gripping the end of a suture, forcing the distal end of the instrument beneath the epidermis within an incision, into the fatty tissue and through the muscle adjacent one side of the incision to force the suture through the muscle.
