Rapid closing surgical closure device
A surgical or wound closure device utilizes a slide fastener for rapidly closing a surgical incision or wound with precise apposition of the sides of the incision. The surgical closure devices are configured for linear incisions, shaped incisions, such as used for wedge biopsy or excisional biopsy, and long incisions, such as used for laparotomy or surgical removal of redundant skin. The surgical closure device may be adhered to the patient's skin prior to making an incision and is subsequently used for closing the incision.
1. A wound closure device, comprising:
a first adhesion parch configured for adhering to a patient's skin;
a second adhesion patch configured for adhering to the patient's skin, wherein the wound closure device has an open position with an approximately elliptical shaped opening formed between the first adhesion patch and the second adhesion patch and has a closed position wherein the first adhesion patch and the second adhesion patch are held in close proximity to each other;
a wire form coupled to the first and second adhesion patches to bias the first and second adhesion patches toward the open position;
a plurality of tension members having a first end and a second end, wherein adjacent tension members are arranged in a non-parallel configuration with one another;
a plurality of catches, wherein each catch is attached to one of the first and second adhesion patches, wherein the first end of each of the tension members is attached to the other of the first and second adhesion patches, and wherein the second end of each of the tension members passes through one of the catches to provide a ratcheting mechanism for selectively closing the patches together.
2. The wound closure device of claim 1 , wherein the first adhesion patch is joined to the second adhesion patch at end portions beyond the opening between the first adhesion patch and the second adhesion patch.
3. The wound closure device of claim 1 , wherein the first ends of the tension members are all attached to the first adhesive patch and the catches are all attached to the second adhesive patch.
4. The wound closure device of claim 1 , wherein the tension members radiate from a common attachment point positioned within the approximately elliptical shaped opening.
5. The wound closure device of claim 1 , wherein the tension members are arranged in a random configuration.
6. The wound closure device of claim 1 , wherein the tension members are made of an elastomeric material to provide a selected range of tension.
7. The wound closure device of claim 1 , wherein the ratcheting mechanism comprises a plurality of barbs formed along the sides of the tension member.
8. The wound closure device of claim 1 , wherein the ratcheting mechanism comprises a plurality of nubs formed along the sides of the tension member.
9. The wound closure device of claim 1 , wherein the tension member comprises a spring member having waves which comprise the ratcheting mechanism.
10. The wound closure device of claim 9 , wherein the tension member is formed from a metal or a polymer less flexible than the metal.
11. The wound closure device of claim 1 , wherein the first and second adhesion patches comprise a continuous patch surrounding a middle opening.
12. The wound closure device of claim 1 , wherein the wire form comprises a metal wire.
13. The wound closure device of claim 12 , wherein the metal wire comprises annealed aluminum, annealed copper, stainless steel, cobalt-chromium, or nickel titanium.
14. The wound closure device of claim 1 , wherein the wire form comprises a rigid plastic or a fiber reinforced composite material.
15. The wound closure device of claim 1 , wherein the wire form comprises a first leg and a second leg.
16. The wound closure device of claim 15 , wherein the first and second legs are coupled to one another at one or more of their ends.
17. The wound closure device of claim 15 wherein the first leg is disposed along the length of the first adhesion patch and the second leg is disposed along the length of the second adhesion patch.
