Embodiment Construction

[0024] The stretching skin device of the present invention includes a skin expander, as shown in one embodiment of the accompanying drawings. Other designs of skin expanders as known in the art may also be used in the present invention.

[0025] The skin expander comprises an elongated straight guide rod 10 . The guide rod 10 has a non-circular, for example rectangular, cross-section. A jaw plate 12 slidable in the length direction is provided on the guide rod 10 . The jaw 12 is longitudinally displaceable on the guide rod 10 , for which purpose the jaw includes a tubular slide 14 which moves on the guide rod 10 through an opening 16 . The inner cross section of the opening 16 matches the outer cross section of the guide rod 10 , so that the jaw 12 can be moved on the guide rod 10 in a non-rotatable manner. A toothed latch mechanism 18 is designed longitudinally of the guide rod 10 . A latch lever 20 is pivotally mounted to the slider 14 with a latch tooth 22 of the lever ...

Abstract

Instrument for stretching the skin for closing wounds, having a skin expander, having at least two jaws mechanically adjustable relative to each other in a tension direction on the skin expander, having barbs associated with the jaws the barbs being anchorable in the skin in the area of the edges of the wound, wherein a tensile force is exerted on the skin by means of the barbs by adjusting the jaws, said force stretching the skin and drawing the edges of the wound toward each other, wherein one or more barbs are each disposed on a carrier extending transverse to the tension direction, wherein the carriers are releasably mounted on the jaws, and wherein the carriers can be fixed in position relative to each other by attachable fixing elements.

Description

technical field [0001] The invention relates to a skin stretching device for closing wounds, as described in the preambles of the claims. Background technique [0002] In addition to skin grafts, known methods of closing large skin wounds include the use of skin extensions. Skin stretching requires the use of a special skin spreader or skin retractor, which has at least two jaws that can be held at opposite edges of the wound by cooperating barbs. The jaws can be adjusted mechanically relative to each other and overlapped to apply a pulling force to the skin to tighten the skin and make the edges of the skin relatively tight. Pulling force is applied for a specified time, and the skin is closed due to its own elasticity, and the skin regenerates and heals the wound. [0003] Skin stretching devices for skin stretching come in different sizes. The barbs are able to move relative to each other by a screw (eg EP0797406B1). There is also a known method in which the barb can ...
