Abstract

The invention discloses a skin wound closure device capable of promoting skin wound healing and characterized by being capable of randomly adjusting stitching force for a wound. The skin wound closure device includes a support structure respectively arranged at both sides of a skin wound, at least one locking device is arranged above the support structure, the locking device includes a locking bar and a locking buckle arranged on the support structure, the locking bar is movably connected within the locking buckle, and a locking member is arranged on the locking buckle and can lock or loosely fit the locking bar in the locking buckle. Arrangement of the locking member allows doctors to loosely fit the locking bar in the locking buckle by controlling the locking member, randomly move the support structure and the locking device towards the direction close to the skin wound or the direction away from the skin wound, and lock the locking bar in the locking buckle by the locking member after proper movement, thus achieving the purpose of randomly adjusting the stitching force for the skin wound. The skin wound closure device is suitable for widespread application to healing treatment of skin wounds.

Claims

1. A skin wound closure device, comprising:

a support structure respectively arranged at both sides of a skin wound,

at least one locking device being arranged above the support structure, the locking device comprising a locking bar and a locking buckle arranged on the support structure, and the locking bar being movably connected within the locking buckle

a locking member arranged on the locking buckle which can lock or loosely fit the locking bar in the locking buckle, and

a through hole arranged in the locking buckle and through which the locking bar passes and is sheathed,

wherein the locking member is a rolling element arranged between an upper surface of the locking bar and a top wall of the through hole.

3. The skin wound closure device of claim 1, further comprising a chute arranged at the top wall of the through hole, wherein the rolling element is arranged in the chute, and a diameter of the rolling element is greater than or equal to a height from an inside top wall of the chute to the upper surface of the locking bar, and smaller than a height from an outside top wall of the chute to the upper surface of the locking bar.

4. The skin wound closure device of claim 3, wherein a bar through a hole in communication with the chute is arranged on the top of the locking buckle.

5. The skin wound closure device of claim 4, wherein a projection for increasing friction force is arranged at the upper surface of the locking bar.

6. The skin wound closure device of claim 5, wherein the support structure respectively located at both sides of the skin wound comprises a support belt and a base belt arranged on an upper surface of the support belt, and the locking buckle is fixedly arranged on the base belt.

7. The skin wound closure device of claim 6, wherein the base belt is arranged at an inside edge of the upper surface of the support belt, and the support belt and an inside edge of the base belt are of an arcuate surface.

8. The skin wound closure device of claim 7, wherein a hypoallergenic adhesive is coated to a lower surface of the support belt.

9. The skin wound closure device of claim 1, wherein the support structure at each side is provided with the locking buckle, and two ends of the locking bar are movably connected with the locking buckle at both sides of the skin wound.

10. The skin wound closure device of claim 1, wherein the locking buckle is only arranged on the support structure at one side of the skin wound, one end of the locking bar is movably connected with the locking buckle, and the other end thereof is fixedly connected to the support structure at the other side.
