In order to solve the problems, the tension adjusting method of the limb skin scar adjusting combined system comprises the following steps:
step 100, two sections of long adhesive tapes 31 with appropriate lengths are cut according to the length of the wound, and the two sections of long adhesive tapes 31 are adhered to the positions close to the two sides of the long and narrow wound.
Step 200, a plurality of independently installed adhesive tape independent fasteners 32 on two sections of long adhesive tapes 31 are respectively fastened on the side surfaces of the two fastener fixing clamping seats 21, and a pair of the two corresponding adhesive tape independent fasteners 32 is formed and provided with a fastener traction mechanism 33.
When the fastener pulling mechanism 33 is installed, the inner telescopic block 331 of the fastener needs to be inserted into the front end socket of the spiral fine adjustment assembly 321, and the bolt installed at the rear end of the spiral fine adjustment assembly 321 is screwed into the inner threaded hole at the front end of the inner telescopic block 331 of the fastener, so that the inner telescopic block 331 of the fastener is fixed inside the spiral fine adjustment assembly 321.
At this time, the strip-shaped buckle rope 332 integrally formed on the inner telescopic block 331 of the fastener passes through the one-way block ring 322 of the clamping block, and the strip-shaped buckle rope 332 is pulled at the other end of the one-way block ring 322 of the clamping block until the adjacent conical integrated clamping block 333 on the strip-shaped buckle rope 332 passes through the one-way block ring 322 of the clamping block, and at this time, the fastener pulling mechanism 33 is preliminarily fixed on the two fastener fixing clamping seats 21.

Step 400, when the two groups of tape independent fasteners 32 are connected with the two long adhesive tapes 31 to tighten the skins on the two sides of the wound to a proper degree, the two suspended plastic bandage bands 11 for four limbs are bent and anastomosed along the four limbs.
Step 500, in the process of bending the four-limb plastic bandage 11, the approximate area covered after being completely bent is determined, and at this time, the two subarea fastener adhesive tapes 23 are attached to the area of the four-limb plastic bandage after being completely anastomosed with the four-limb parts.
Step 600, pulling the plurality of movable sliding buckles 221 of the binding band outwards along the plastic binding bands 11 of the four limbs in sequence, pressing down the corresponding positions on the partition fastener adhesive tapes 23 after the movable sliding buckles 221 of the binding band move outwards for a proper distance, and uncovering the independent adhesive tape sealing paper 233 covering the skin adhesive tape 232 on the partition fastener adhesive tape 23 right below the movable sliding buckles 221 of the binding band, so that the part of the partition fastener adhesive tape 23, from which the independent adhesive tape sealing paper 233 is uncovered, is adhered to the skin.
Step 700, after all the movable sliding buckles 221 of the binding band are fastened and fixed by the partition fastener adhesive tape 23, the main body parts of the two plastic binding bands 11 of the four limbs are completely anastomotic at the outer sides of the four limbs, and the tail ends of the two plastic binding bands 11 of the four limbs are fixed by using the movable fasteners 13, so that the plurality of movable sliding buckles 221 of the binding band naturally draw the skin of the corresponding area adhered by the partition fastener adhesive tape 23 in a layered manner under the action of the tension spring assembly 223.
After the plurality of movable sliding buckles 221 for binding band are pulled outwards along the plastic binding band 11 to a proper distance, the fixedly connected snap buckles 224 arranged on the lower surface of the fixing clamping seat 21 of the fastener are buckled with the snap buckles 231 on the upper surface of the adhesive tape 23 of the lower subarea fastener, when the two plastic binding bands 11 are bent to be inosculated and surround the four limbs, the movable fasteners 13 are used for connecting the tail ends of the two plastic binding bands 11, at this time, the plurality of movable sliding buckles 221 for binding band are driven to slide towards the direction of the fixing clamping seat 21 of the fastener under the action of the tension spring assemblies 223, and the skin adhesive tape 232 of the independent adhesive tape sealing paper 233 is uncovered on the lower surface of the adhesive tape 23 of the subarea fastener buckled below along the sliding connection of the movable sliding buckles 221 for binding band 221 for independent adhesive tape to pull the skin, and the tension force provided by the tension spring assemblies 223 is gradually decreased towards the outside, so that the intensity of the subarea fastener adhesive tape 23 for pulling the multi-layer skin on both sides of the wound is gradually decreased, effectively improving the comfort level of the traction skin.
In addition, the bolt for controlling the movement of the spring adjusting slider 222 at the front end of the movable binding belt slider 221 is screwed, so that the spring adjusting slider 222 moves a little along the movable binding belt slider 221, thereby the tension of the tension spring assembly 223 mounted on the movable binding belt slider 221 can be adjusted a little after the movable binding belt slider 221 is fastened and fixed, and the bolt for controlling the spring adjusting slider 222 and the connection point of the front end tension spring assembly 223 on the movable binding belt slider 221 are staggered up and down, so that the tension of the rear end tension spring assembly 223 can be adjusted without affecting the front end tension spring assembly 223.
The above embodiments are only exemplary embodiments of the present application, and are not intended to limit the present application, and the protection scope of the present application is defined by the claims. Various modifications and equivalents may be made by those skilled in the art within the spirit and scope of the present application and such modifications and equivalents should also be considered to be within the scope of the present application.
