DEVICES AND METHODS FOR CLOSURE OF WOUNDS

摘要

The invention encompasses devices and methods used to provide wound closure based on rings positioned within the tissue layers of the wound opening (with the rings regionally separate the wound depth tissue layers into 2 compartments), followed by suture transport through the rings and full-thickness tissue layers of both compartments. Upon suture transport via synchronous or asynchronous manner and device removal, wound closure is achieved by tying the 2 ends of the suture without incorporating tissue above the level of the rings such as skin. When the device is applied to abdominal or chest wall wound opening, all tissue layers except the skin are incorporated in the suture closure of the wound. The closure process can be performed in a simple, reliable, and expeditious manner.

主权项

1. A device for closing a skin layer, a subcutaneous layer and a fascia layer of a trocar opening in the abdominal wall, the device comprising:
an elongate member having a proximal end with a proximal end diameter and a distal end with a distal end decreasing diameter such that the distal end diameter is largest at the intersection with the proximal end, wherein the maximal distal end diameter is greater than the proximal end diameter; a first rod member attached substantially perpendicularly to a first wing member to form a first elbow, the first elbow pivotally attached to a first side of the elongate member at the proximal end, the first wing having a lumen; a second rod member attached substantially perpendicularly to a second wing member to form a second elbow, the second elbow pivotally attached to a second side of the elongate member at the proximal end, the second wing having a lumen; and wherein the device is configured such that when the first and second rod members are in a position substantially perpendicular to the elongate member, the first and second wing members are substantially parallel to the elongate member at the proximal end, and when the first and second rod members are rotated towards the elongate member into a position substantially parallel to the elongate member, the first and second wing members are automatically rotated into a position substantially perpendicular to the elongate member inside the trocar opening such that the first and second wing members are positioned within the subcutaneous tissue layer between the skin and fascia layers of the trocar opening.
