Abstract

The invention discloses a self-adaptive stereoscopic tension reducer for skin wound healing and a control and application method thereof. The stereoscopic tension reducer comprises a bottom patch and a rigid bridging piece which are detachably connected, and is integrated with a tension sensing module, a control unit and an adjusting driving module, wherein the rigid bridging piece is connected with an adjusting buckle on the bottom patch through a flexible adjusting drawstring. The control unit receives a target recovery level set by a user, synthesizes the reference and the target level to determine a dynamic tension safety threshold range, and controls the driving module to adjust the tension of the drawstring by comparing real-time tension data with the threshold range so as to realize closed-loop self-adaptive adjustment. In the preferred scheme, a wound visual monitoring module is also provided for evaluating the healing quality and optimizing a regulation strategy library. The invention solves the problem that the skin tension and dynamic healing process of different individuals cannot be individually adapted, and can improve the tension reducing accuracy, the wound healing quality and the experience of doctors and patients.

Description

Self-adaptive stereoscopic tension reducer for skin wound healing and control and application method thereof Technical Field The invention relates to the technical field of medical equipment, in particular to a tension reducing device for skin wound care after operation or trauma, and especially relates to a skin wound healing self-adaptive stereoscopic tension reducing device capable of performing self-adaptive tension adjustment according to personal skin characteristics and wound healing states and a control and application method thereof. Background The quality of wound healing and scarring of the skin are affected by multiple factors, with the mechanical tension at the wound edges being one of the key biomechanical factors. Too high tension may affect local blood circulation, resulting in poor healing or scarring. In order to reduce wound tension, techniques such as 'tension reducing suture' and the like are clinically applied, and related researches also put forward a qualitative classification concept based on tension magnitude so as to guide clinical decisions. The auxiliary tension reducing materials commonly used in clinic at present are planar or strip tension reducing materials, and in use, the auxiliary tension reducing materials have a plurality of limitations that firstly, the auxiliary tension reducing materials are directly attached to the surface of a wound or a suture port, are easy to press the wound to influence local blood transportation and exudation management, secondly, the auxiliary tension reducing materials need to be removed when changing dressings or removing stitches, the operation is inconvenient, and the wound is possibly pulled, thirdly, the planar attachment is difficult to adapt to the shape of the wound which is turned outwards and raised after the ultra tension reducing suture technology is adopted, and even adverse effects can be generated. Further, there are still some technical limitations in the prior art in converting the above-described strain relief concept into an instrumented, sustainable dynamic regulation scheme. At present, clinical evaluation of initial tension of wounds mainly depends on subjective experience judgment such as palpation and the like, and lacks an objective quantitative reference, so that subsequent instrument intervention lacks a consistent and repeatable personalized adjustment starting point. When the regulation parameters are set, the existing tension reducing devices generally fail to take the difference of the mechanical properties of the skin of an individual as the reference input of regulation based on preset general parameters, so that the pertinence of the intervention is to be enhanced. In the adjustment mode, many tension reducing devices rely on manual adjustment or simply provide a static fixed tension maintenance. In this mode, the device cannot sense and respond to dynamic fluctuation of the tension around the wound caused by physical activity, tissue swelling change and the like in real time, and it is also difficult to realize a closed-loop control process of continuous monitoring, automatic judgment and instantaneous fine adjustment, so that it is difficult to maintain the tension stably at a target interval. In addition, from the point of view of a regulation strategy library, the logic of the existing scheme is often single, the control target is usually to maintain a fixed tension value, or on-off regulation is performed based on a simple threshold value, but different expectations and targets of users on wound healing results are not fully considered and fused, so that the treatment scheme is difficult to flexibly adapt and optimize according to different clinical requirements or patient wishes on the basis of the same hardware. In summary, in the prior art, not only are common tension reducing materials limited in morphology and use mode, but also evaluation of wound tension depends on subjective experience, and the adjustment of the existing tension reducing device also lacks objective individuation reference, dynamic closed loop response capability and strategy suitability for different healing targets. Therefore, there is a need in the art for a stereoscopic tension reducer that can avoid direct compression of a wound, facilitate clinical operation, and that can acquire objective and quantitative benchmarks, integrate personalized goals, and achieve dynamic adaptive closed-loop adjustment to improve the accuracy, safety, and personalization level of wound tension control. Disclosure of Invention Aiming at the defects existing in the prior art, the invention aims to provide a self-adaptive stereoscopic tension reducer for skin wound healing and a control and application method thereof. In order to achieve the above purpose, the invention adopts the following technical scheme: in a first aspect, there is provided an adaptive stereoscopic tension reducer for skin wound healing, comprising: at least two bottom patches
