Technical Field

The invention belongs to the technical field of suturing devices, and relates to a minimally invasive incision suturing device.

Background

In the medical field of today, the suture mode of the operation incision has a great development. The traditional incision stitching instrument usually adopts a stitching line or a stitching nail to stitch, the two stitching modes can be suitable for incisions with various shapes, but in the process of wound healing, the wounds can be stimulated by the stitching line or the stitching nail to cause allergic infection and the like to affect the healing effect, meanwhile, the stitching effect of the stitching line and the stitching nail on the wounds is limited, and in the process of healing, the wounds can be torn due to severe movement of patients.

In recent years, a novel stitching instrument has been developed, which comprises two patches adhered to the skin, and the two patches are connected by a binding belt or other adjusting devices, and when in use, the two patches are directly adhered to the skin on both sides of a wound, and then the two patches are tensioned by the adjusting devices such as the binding belt, and the patches drive the wound skin to approach each other, so as to close the wound, and in the way, the wound is not stimulated by foreign objects in the process of closing the wound, so that a patient is not injured additionally, and meanwhile, the skin on both sides of the wound is tensioned by the patches, so that the effect is more stable, and the wound is not easy to tear, but the stitching instrument has certain defects that the stitching instrument cannot be applied to the wound with a complicated shape, such as the stitching instrument disclosed in the invention patent applications with the application numbers of 201810744738.7 and 201910536736.3.

When the stitching instrument is used, the adjusting devices are distributed on the two patches at equal intervals, when the adjusting devices tension the two patches, the tension formed by the two patches is not uniform, the uneven tension can be applied to the skin near the wound through the patches and finally applied to the wound, the closing of the wound is affected, particularly, under the condition that the wound needs to be stitched together by matching with a suture line, the suture line can be firstly used for stitching the wound under the condition, then the stitching instrument is attached, the best stitching effect can be achieved if the tension formed by the adjusting devices can act between two stitching points, and the stitching instrument in the prior art cannot adjust the tension acting position of the adjusting devices on the patches.
