Description
Technical Field
The invention relates to the technical field of medical equipment, in particular to a combined device for regulating the tension of skin scars of limbs.
Background
The pathogenic mechanism of keloid scars is not clear. In etiology, trauma, infection or inflammation, increased skin tone, local immune factors, endocrine factors, family genetic predisposition, etc. may be related to the formation of keloid scars. The local skin tension is the clear reason for scar hyperplasia, so that the reduction of the transverse tension of the skin is an effective method for reducing the scar hyperplasia.
The existing methods for reducing skin tension often adopt subcutaneous suture tension reduction and free skin flap tension reduction. However, the existing method for reducing the skin tension has poor effect, the tension is reduced through the wound suture, and besides the effect, the suture per se can stimulate scar hyperplasia, and the scar is often formed at the wound suture. Especially in the four limbs, the scar hyperplasia is obvious due to the large skin tension.
Disclosure of Invention
In view of the above, there is a need to provide a combined device for regulating skin scar tension of limbs, which solves the technical problem of the prior art that skin tension cannot be reduced well.
The invention provides a tension adjusting combination device for skin scars of limbs, which comprises: the drawing mechanism can be separated or fixed at one or more positions on the arc-shaped cross rod.
Furthermore, the traction mechanism further comprises a crochet hook fixing piece and a position fixing piece connected with the crochet hook fixing piece, the traction crochet hook is fixed on the crochet hook fixing piece, and the position fixing piece can be separated from or fixed on one or more positions on the arc-shaped cross rod.
Furthermore, a plurality of position holes are formed in the arc-shaped cross rod, and a protruding block matched with the position holes is arranged on the position fixing piece.
Still further, the pulling mechanism further comprises a protection spring, and the crochet hook fixing piece is connected with the position fixing piece through the protection spring.
Furthermore, the two drawing mechanisms are arranged oppositely, the position fixing piece of one drawing mechanism is close to one end of the arc-shaped cross rod, and the position fixing piece of the other drawing mechanism is close to the other end of the arc-shaped cross rod.
Still further, the protection spring applies a pre-tightening force to the crochet hook fixing piece towards the position fixing piece.
Furthermore, the extension direction of the crochet hook fixing piece is perpendicular to the arc-shaped cross rod, and a plurality of the traction crochet hooks are arranged along the extension direction of the crochet hook fixing piece.
Furthermore, scales are arranged on the arc-shaped cross rod.
Further, two ends of the arc-shaped cross rod are respectively provided with a protection piece.
Further, the thickness of the protection member is greater than the thickness of the arc-shaped crossbar.
The invention uses the assembly part which reaches the subcutaneous layer deeply and uses the traction hook to pull the skin far away from the wound, thereby reducing the tension of the wound end and reducing the scar hyperplasia. As no suture is needed, the suture can avoid stimulating the scar hyperplasia. The arc cross bar assembly is more attached to cylindrical structures of four limbs, and the traction force is uniform. The arc-shaped cross rod is provided with scales, so that different tension sizes can be adjusted, and the suitable tension with the minimum scar is achieved. The protective springs on the two sides can effectively protect the injury of the far-end skin caused by excessive traction.

Specifically, during the use, with arc horizontal pole 1 and four limbs laminating, catch on the skin of keeping away from the wound with tractive crochet hook 21, slip tractive mechanism 2 carries out the tractive to skin, and after tractive mechanism 2 arrived suitable position, fix tractive mechanism 2 on arc horizontal pole 1, fix arc horizontal pole 1 on four limbs through the gypsum.
When the whole device is used, the suture can be omitted, and the device can also be used in cooperation with the suture. When the suture is not used, the suture can be prevented from stimulating scar hyperplasia because the suture pulls the skin.
According to the invention, the skin far away from the wound is pulled by the pulling hook through the assembly part reaching the subcutaneous layer, so that the tension at the wound end is reduced, and the scar hyperplasia is reduced. The suture is not needed, so that the suture is prevented from stimulating scar hyperplasia. The arc cross bar assembly is more attached to cylindrical structures of four limbs, and the traction force is uniform.
Example two
As shown in fig. 1 to fig. 3, a schematic structural diagram of a combined apparatus for regulating tension of skin scars on limbs according to an embodiment of the present invention includes: the device comprises an arc-shaped cross rod 1 and two traction mechanisms 2 which can slide on the arc-shaped cross rod 1, wherein the traction mechanisms 2 can be separated or fixed at one or more positions on the arc-shaped cross rod 1;
each of the pulling mechanisms 2 comprises one or more pulling crochet hooks 21, a crochet hook fixing member 22, a position fixing member 23 connected with the crochet hook fixing member 22, and a protection spring 24, wherein the pulling crochet hooks 21 are fixed on the crochet hook fixing member 22, the extending direction of the crochet hook fixing member 22 is perpendicular to the arc-shaped cross bar 1, the pulling crochet hooks 21 are arranged along the extending direction of the crochet hook fixing member 22, the arc-shaped cross bar 1 is provided with a plurality of position holes 11, the position fixing member 23 is provided with a convex block 231 matched with the position holes 11, the position fixing member 23 can be separated or fixed on one or more positions on the arc-shaped cross bar 1, and the crochet hook fixing member 22 is connected with the position fixing member 23 through the protection spring 24;
