Embodiment 1

[0023] like figure 1 Shown is a schematic structural view of a combined device for adjusting the tension of extremities skin scars according to the present invention, including: an arc-shaped cross bar 1, two pulling mechanisms 2 that can slide on the arc-shaped cross bar 1, each of the pulling mechanisms 2 One or more pulling hooks 21 are arranged on the pulling mechanism 2 , and the pulling mechanism 2 can be separated or fixed at one or more positions on the arc-shaped cross bar 1 .

[0024] Specifically, when in use, fit the arc-shaped crossbar 1 to the limbs, hook the pulling hook 21 on the skin away from the wound, and slide the pulling mechanism 2 to pull the skin. After the pulling mechanism 2 reaches a suitable position, The pulling mechanism 2 is fixed on the arc-shaped cross bar 1, and the arc-shaped cross bar 1 is fixed on the limbs by plaster.

[0025] When the whole device is in use, it can be used without sutures or with sutures. When sutures are not used, sin...

Embodiment 2

[0028] like Figure 1 to Figure 3 As shown, a schematic structural view of a combination device for adjusting the tension of extremities skin scars according to an embodiment of the present invention, including: an arc-shaped cross bar 1, two pulling mechanisms 2 that can slide on the arc-shaped cross bar 1, the The pulling mechanism 2 can be separated or fixed at one or more positions on the arc-shaped cross bar 1;

[0029] Each of the pulling mechanisms 2 includes one or more pulling hooks 21, a hook fixing part 22, a position fixing part 23 connected with the hook fixing part 22, and a protection spring 24, and the pulling hooks 21 are fixed on On the crochet hook fixing member 22, the extension direction of the crochet hook fixing member 22 is perpendicular to the arc-shaped cross bar 1, and a plurality of the pulling hooks 21 are arranged along the extension direction of the crochet hook fixing member 22, and the arc-shaped The crossbar 1 is provided with a plurality of ...

Abstract

The invention discloses a four-limb skin scar tension adjusting combined device. The device comprises an arc-shaped cross bar (1), two pulling mechanisms (2) which can slide on the arc-shaped cross bar (1), each of the pulling mechanism (2) is provided with one or more pulling crochet hooks (21), and the pulling mechanisms (2) can be separated or fixed in one or more positions on the arc cross bar(1). The skin away from a wound is pulled through an assembly going deep to a subcutaneous layer and the pulling crochet hooks, so that the tension at the wound end is reduced and scar hyperplasia isreduced. As no sutures are required, the sutures are avoided to stimulate scar hyperplasia. The arc-shaped cross bar assembly fits more closely to cylindrical structures of the four limbs, and the pulling force is even. The arc-shaped cross bar is equipped with scales, which can adjust different tensions, so as to achieve the smallest suitable tension for scars. Protective springs on both sides can effectively protect the distal skin from damage caused by excessive pulling.

Description

technical field [0001] The invention relates to the related technical field of medical equipment, in particular to a combined device for adjusting the tension of extremity skin scars. Background technique [0002] The pathogenic mechanism of keloids is still unclear. In terms of etiology, trauma, infection or inflammation, increased skin tension, local immune factors, endocrine factors, and family genetic predisposition may all be related to the formation of keloids. Among them, high local skin tension is the clear cause of scar hyperplasia, so reducing the lateral tension of the skin is an effective method to reduce scar hyperplasia. [0003] Existing methods to reduce skin tension often adopt subcutaneous sutures and free skin flaps to reduce tension. However, the existing method of reducing skin tension is not effective. Reducing tension through wound sutures, in addition to the general effect, the sutures themselves will stimulate scar hyperplasia, and often the wound ...
