Description

Technical Field

[0001] The present invention relates to the field of medical cosmetology technology, and in particular to a skin tension reducer and a tension reducing method based on full-cycle regulation. Background Art

[0002] Skin performs important physiological functions in the human body, including protecting the body from external damage, regulating body temperature, and sensing touch. However, after trauma or surgery, the recovery process of the skin and its underlying tissues may be affected by excessive and uneven tension, leading to slow wound healing and even problems such as wound dehiscence, infection, and scarring. Therefore, controlling and managing tension in the wound area is crucial for promoting wound healing and minimizing scar formation. Traditional tension management methods, such as layered suturing and flap transplantation, can alleviate local tension to a certain extent, but these methods rely on the health of the tissue in the wound area and may result in side effects such as wound expansion or prolonged postoperative recovery. Furthermore, traditional suturing techniques cannot precisely regulate tension in the wound area and may be ineffective in some specific locations, such as joints or areas of loose skin. Therefore, how to achieve precise tension control through scientific means to prevent excessive local skin tension from becoming a barrier to healing has become an urgent issue in the medical community.

[0003] As a specially designed medical device, the skin tension reducer aims to precisely adjust the tension in the wound area through the principles of mechanical mechanics. Its basic principle is to apply directional tension through the device to gradually reduce the skin tension on both sides of the wound, thereby improving the wound healing environment and avoiding the negative impact of excessive tension on the skin and tissue.

[0004] In the prior art, Chinese Patent Publication No. CN113712619A discloses a skin tension reducer that achieves adjustment and secure fixation primarily through the coordinated design of first and second adjustment plates and a strapping band. However, this solution suffers from issues such as low tension adjustment accuracy and limited adaptability. Chinese Patent Publication No. CN103892877A discloses a skin tension reducer that includes patches on either side of a skin wound and a fixed frame strip, with a clamping device on the fixed frame strip to adjust the connecting strip. However, this skin tension reducer faces issues such as adaptability to complex wound locations and long-term wear comfort. In particular, its applicability for curved or large wounds and the need for reverse adjustment tools are limited. Publication No. CN217772420U discloses an adjustable skin tension reducer that primarily includes an adjustment plate, a rotating handle, a connecting rod, a rotating shaft, a baffle, and a steel wire to adjust tension on both sides of the wound. However, the durability of the steel wire and spring may decrease with prolonged use, and its adaptability to complex or irregular wounds is limited.

[0005] In summary, existing skin tension reducers have problems such as poor adaptability, low adjustment accuracy, poor comfort, and complex operation. In addition, many tension reducers are difficult to adapt to wounds of different shapes or types, and the tension adjustment accuracy is insufficient, which affects the healing effect. Summary of the Invention

[0006] The purpose of the present invention is to propose a skin tension reducer and tension reduction method based on full-cycle adjustment to solve the problems of difficulty in adjusting the tension reducer in the later stage, inaccurate tension control, easy falling off and high allergy rate in the prior art.

[0007] In order to achieve the above object, the technical solution adopted by the present invention is as follows:

[0014] As a further improvement of the present invention, a plurality of mutually parallel strip-shaped ventilation grooves are distributed on the left auxiliary film and the right auxiliary film.

[0026] (2) The left and right auxiliary films are made of medical-grade skin-friendly silicone material, which is soft, breathable, and biocompatible, reducing the risk of skin irritation and allergies; the special microstructure at the bottom increases friction to prevent falling off, and also has a sweat-absorbing function, creating a good healing environment for the wound; the surface strip-shaped ventilation grooves can ensure air circulation, accelerate sweat evaporation, and improve patient comfort without affecting the structural strength and fitting effect of the film;

[0027] (3) Multiple tension adjustment devices are symmetrically and evenly distributed to ensure balanced and stable tension; conical spiral tensioners are provided at both ends of each tension adjustment device, which can simultaneously perform symmetrical pulling to ensure uniform tension on both sides of the wound; and the tension of different tension adjustment devices can be set to different tensions according to the width of the wound, so that the overall width of the wound tends to be the same;

[0028] (4) The two traction belts are made of high-strength and low-elastic modulus medical fiber materials, which can not only bear sufficient tension but also adapt to the slight deformation during skin repair to avoid additional pulling damage; the fixed guide block has a smooth surface and a circular guide hole design to ensure the linear movement of the traction belt, accurately transmit tension and reduce friction; the conical spiral tensioner is easy to operate, which can not only clamp the traction belt to prevent loosening, but also realize the locking and disassembly functions;

DETAILED DESCRIPTION

[0039] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the described embodiments of the present invention, all other embodiments derived by persons of ordinary skill in the art are within the scope of protection of the present invention.

[0040] like Figure 1 The figure shows a full-cycle adjustable skin tension reducer, comprising a left auxiliary film 1, a right auxiliary film 2, three tension adjustment devices 3, and a tension detection device. The left and right auxiliary films 1 and 2 are identical in size and specifications, spaced a certain distance apart, with their top ends aligned. The three tension adjustment devices 3 are spaced parallel to each other.

[0041] like Figure 2 As shown, the left auxiliary film 1 and the right auxiliary film 2 are made of medical-grade, skin-friendly silicone. Micro-protrusions 1-1 are arranged in a display pattern on the back of each film. Made of medical silicone, these micro-protrusions 1-1 not only increase friction with the skin to prevent the tension reducer from accidentally falling off during daily activities, but also provide a certain sweat-absorbing function, keeping the skin around the wound dry and clean, creating a favorable environment for wound healing.

[0042] like Figure 3 and Figure 4 As shown, the tension adjustment device 3 includes a fixed guide block 3-1, a traction belt 3-2 and a tapered spiral tensioner 3-3. The fixed guide block 3-1 is provided with two parallel guide holes 3-1-1 for the traction belt 3-2 to pass through and guide the traction belt 3-2. The fixed guide block 3-1 is also provided with a tapered inner hole (not shown in the figure), which is provided with an internal thread, and the tapered spiral tensioner 3-3 is threadedly connected to the tapered inner hole. Specifically, as shown in FIG. Figure 5 As shown, the tapered screw tightener 3-3 includes a rotation 3-3-1 and a tapered external thread 3-3-2.

[0043] One end of the traction belt 3-2 is fixed to the conical spiral tightener 3-3, and the other end is fixed to the fixed guide block 3-1 on the right auxiliary film 2. Another traction belt 3-2 on the tension adjustment device 3 is installed in the opposite direction, and the two traction belts 3-2 are arranged in parallel.

[0044] like Figure 6 As shown, the tension detection device includes a tension collection board 4, a handheld display 5, and a strain gauge 6. The tension collection board 4 is mounted inside one of the two fixed guide blocks 3-1 of each tension adjustment device 3. The strain gauge 6 is attached to the traction belt 3-2 and connected to the tension collection board 4 via a wire. The tension collection board 4 has a built-in wireless transmitter module for wireless communication with the handheld display 5. The operating principle of the tension detection device is to detect the tension of the traction belt 3-2 via the strain gauge 6, transmit the tension signal to the tension collection board 4, and then send it to the handheld display 5 for display.

[0045] The present invention also proposes a skin tension reduction method, which specifically comprises the following steps:

[0046] Step S1: selecting a skin tension reducer of appropriate size according to the length and width of the patient's skin wound;

[0047] Step S2: Tear off the protective films on the back of the left and right auxiliary films, and stick them on the corresponding positions on both sides of the patient's wound respectively;

[0048] Step S3: Pass the traction belt through the corresponding fixed guide block 3-1 and the tapered spiral tightener and fix them. Attach the two fixed guide blocks 3-1 to the corresponding positions on the front of the left auxiliary film and the right auxiliary film respectively, keeping them at the same height. Select the number of tension adjustment devices and the distance between two adjacent tension adjustment devices according to the length of the wound.

[0049] Step S4: Tighten the conical screw tightener on each tension adjustment device 3 at the same time to increase the tension of the traction belt, and dynamically read the tension of the traction belt through the strain gauge and tension acquisition board in combination with the matching portable handheld display;

[0050] Step S5: When the tension of the traction belt reaches a predetermined value, stop tightening the conical spiral loosener and fix the traction belt; when the wound is of regular shape, keep the tension of each traction belt consistent; when the wound is of irregular shape, dynamically read the tension of the traction belt through the strain gauge and the tension acquisition board in combination with the matching portable handheld display according to the patient's wound width from large to small, and accurately adjust the tension of the two traction belts of the tension adjustment device one by one, so as to move from the position with the larger wound width to the position with the smaller wound width, and reduce the tension one by one to meet the tension requirements of different positions of the same wound;

[0051] Step S6: Repeat steps S5 and S6 according to the degree of wound healing to achieve dynamic and precise adjustment of the traction belt tension;

[0052] Step S7: When the wound is healed, loosen the conical spiral tensioner to remove tension from the traction belt;

[0053] Step S8: Gently tear off the left auxiliary film and the right auxiliary film respectively to complete the tension reduction operation.

[0054] The advantage of the present invention is that the tension adjustment device 3 can be adjusted in both directions, and the length of the traction belt 3-2 can be easily fine-tuned through the conical spiral tightener 3-3, thereby shrinking the wound and controlling the wound shape. By setting the tension detection device 3, the tension of each traction belt 3-2 can be obtained in real time. If there is a change in the tension value, it can be adjusted in a targeted manner. The present invention can be adjusted for regular and irregular wounds, and can be observed through the handheld display 5, and the traction belt 3-2 that produces the tension change can be adjusted. The present invention can be adjusted throughout the entire cycle of wound tension reduction, so that the wound shape can be dynamically managed to perfectly achieve the purpose of tension reduction.

[0055] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes that can be made within the scope of knowledge possessed by technicians in the relevant technical field without departing from the spirit of the present invention are all within the scope of protection of the claims of the present invention.
