Description
Technical Field
The application relates to a surgical medical instrument and trauma rehabilitation equipment, in particular to a flexible skin traction system.
Background
In the rehabilitation treatment of severe trauma, the skin is cut off due to laceration or necrosis, and after the subcutaneous trauma is treated, the skin edge at the lacerated part needs to be slowly and continuously pulled to gradually proliferate, so as to achieve the purposes of re-covering the wound surface and recovering the skin function. The skin grows relatively slowly and the stretching process therefore lasts from weeks to months. During the stretching process, the stretching force needs to be in the size and direction according to the treatment requirement and the specific condition of the patient, otherwise, uneven skin growth (under-stretching condition) or failure of stretching (over-stretching condition) can be caused.
In the prior art, such as CN104826219A, the principle is to pierce the puncture needle 34 into the skin at the edge of a wound, and then slowly draw the puncture needle to the distance by using a three-group screw mechanism to pull the skin. The traction device pulls the skin through a mechanism structure, the pulling force is difficult to adjust, and the body feeling of a patient is poor.
A pulling system capable of adjusting the pulling force is also available in foreign countries, such as US10076386B2, which uses a torsion spring to tighten the pulling wires of all anchor points, determines the pulling force through a constant force spring, and displays the specific pulling force reading through the scale on the housing. Also, for example, CN110432994A, this solution employs a tension spring, which is pulled by a puncture needle or a steel wire that penetrates the skin, and also visually displays the pulling force by a scale.
However, the pulling force of the traction apparatus is generated by a steel wire device, the contour of the human body is not a plane but has a radian everywhere, and the steel wire with the pulling force presses and cuts skin and meat tissues to cause the fracture of the tissues, which has certain defects.

Detailed Description
The present invention will be further described with reference to the following examples.
As shown in fig. 1, a flexible skin stretching system according to the present application is applied to a wound 1 on the surface of a limb, characterized in that: comprises at least 3 anchors 3 fixed on the skin surface layer 2, and any two adjacent anchors 3 are connected in such a way that: one end of a traction line 4 is wound and fixed on a winding post 8 of a first anchor device 3, the other end of the traction line 4 is fixedly connected with an elastic part 6, the elastic part 6 is sleeved in a sleeve 5, the sleeve 5 is arranged in the skin surface layer 2 at the edge of the wound 1 in a penetrating way, the other end of the elastic part 6 is fixedly connected with one end of another traction line 4, and the other end of the traction line 4 is wound and fixed on the winding post 8 of a second anchor device 3;
the position on the anchor 3 where the pulling line 4 passes is provided with scales 7, the pulling line 4 is provided with marks so that the elastic parts 6 are at the positions of the scales 0 when the elastic parts are at the original length, and the pulling force on each elastic part 6 is changed by adjusting the winding condition of each section of the pulling line 4 on the winding post 8, so that the pulling force on each side of the wound 1 is adjusted.
The main point of this scheme lies in that the anchor is fixed on the skin top layer, and in the technical data quoted in the background art, the force regulator is often unset, and this brings the hidden danger for the stability of device, also makes the patient face the risk that the device dislocates, and the fixed mode of anchor is easily found and various, can adopt the mode in citation file 3 for example, make the anchor stable and can bear certain pulling force on the skin top layer can.
The main point of the scheme is that,
further, the elastic member is a spring 9, and the sleeve 5 is made of a flexible material.
In this case, the spring does not need to be in a flat state, but is adapted to various shapes to the skin of the wound of the human body by the sleeve, but these do not affect the generation of the required pulling force, and do not cut the tissue of the human body because the pulling wire must be broken straight, as in the second pulling device described in the background art.
The main point of the scheme is that each section of elastic body can generate different pulling forces. In both the first and second types of retractors, the force adjusting device is often concentrated in one, so that all the drawing surfaces have the same drawing force. However, the skin fibers of the human body are directional, the prosthetic growth is also in accordance with the original direction, the pulling force required by each side of the wound is not always the same, and the pulling mode should be specifically formulated according to the position of the wound and the condition of injury.
After the skin grows for a period of time, the pulling force becomes loose, the pulling force needs to be adjusted, and the pulling force can be tightened again only by winding the pulling wire on the original winding post or other winding posts for the required number of turns.
That is to say that the first and second electrodes,
further, the number of the winding posts is at least 4.
In this solution, since the anchors are fixed, the elastic members therebetween have different pulling forces depending on the winding, and are read and displayed by the scale.
Further, the number of the anchors is 4.
Further, the anchor holding positions are selected from the wound contour corner positions.
Further, the number of anchors takes the value of the number of corners of the wound profile.
I.e. a substantially quadrangular wound, four anchors are used, and so on.
Furthermore, the sleeve is made of silica gel.
Furthermore, the sleeve is formed by weaving medical steel wires.
While one embodiment of the present invention has been described in detail, the description is only a preferred embodiment of the present invention and should not be taken as limiting the scope of the invention. All equivalent changes and modifications made within the scope of the present invention shall fall within the scope of the present invention.
