TECHNICAL FIELD
[0001] The present application relates to the technical field of medical devices, in particular to a soft tissue expander for improving skin regeneration efficiency. BACKGROUND
[0002] The soft tissue expander, also known as skin soft tissue expander (hereinafter referred to as expander), is commonly used for plastic and reconstructive surgical treatment, and is widely used in clinical treatment. The expander is designed by using the physiological function of skin soft tissue expansion under certain tension to increase the area. The increased skin soft tissue obtained by tissue expansion is used to repair the tissue trauma or tissue defect to be treated, or to reconstruct the corresponding tissue organ. The increased skin soft tissue by expansion has similar color, texture, or hair to the adjacent skin tissue, and does not produce new defects and deformities, thereby obtaining good plastic and cosmetic and repair and reconstruction effect.
[0003] The structure of the ordinary expander is composed of an expansion capsule, a catheter and a water injection pot. The patient needs to gradually increase the mechanical tension of the skin by twice water injection per week, so as to complete the skin regeneration. Such a cycle usually takes three months to one year, and the expansion process is long, and the patient's implanted expander becomes heavier after water injection, which brings inconvenience to life.
[0004] Therefore, it is necessary to design a soft tissue expander for improving skin regeneration efficiency.

[0026] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the drawings used in the description of the embodiments or the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained from these drawings without creative effort.
[0027] Figure 1 This is a schematic diagram of a soft tissue expander for improving skin regeneration efficiency, as described in Example 1. Detailed Implementation
[0028] To make the technical means, creative features, objectives and effects of this patent easy to understand, the invention will be further explained below with reference to specific illustrations.
[0029] This invention, based on existing research, proposes a novel skin soft tissue expansion mode that improves the efficiency of current expansion methods. Based on practical experience, the inventors have developed a soft tissue expander that enhances skin regeneration efficiency through vibration, and uses different vibration modes to alleviate mild pain or discomfort caused by nerve compression during expansion.
[0030] The improvement of this invention lies in the addition of a vibration massage device to the existing soft tissue expander. This vibration massage device is located within the cavity of the expander sac and is encapsulated in silicone. Furthermore, this vibration massage device can be purchased or customized. Manufacturers of massage devices or medical device development companies can customize similar products. The selected vibration modes include sinusoidal vibration, random vibration, fixed-frequency vibration, and composite vibration. For example, a miniature vibration massage device, which is an implantable miniature vibration motor, can be purchased online. Currently, a suitable motor on the market is a miniature vibration motor with an outer plastic shell, weighing 1g. The outer plastic shell is 13.4mm long, 5.6mm wide, and 5mm high; the inner motor has a diameter of 4mm; the suitable voltage is 3V-3.7V, and the current is 100mA. Products of this specification can be used, but are not limited to. Its remote control method is a mature existing technology.
[0031] The present invention will now be described in further detail.
[0032] See Figure 1The soft tissue expander 1 for improving skin regeneration efficiency comprises an expansion bag 11, a water injection pot 12, a catheter 13 and a massage vibration device 14. The expansion bag 11 and the water injection pot 12 are communicated through the catheter 13. Since the expansion bag 11, the water injection pot 12 and the catheter 13 need to be embedded in the lower layer of the skin, the medical-grade medical silica gel material is used to prevent infection. The massage vibration device 14 in the embodiment is arranged in the inside of the expansion bag 11, and the outside of the massage vibration device 14 is wrapped with a silica gel layer (not shown in the figure), so that the mechanical force can be transmitted and contact with physiological saline and other fillers in the inside of the expansion bag 11 is avoided, and thus the safety is high. The massage vibration device 14 uses a miniature massage vibration device which is powered by a built-in battery or wireless charging. The miniature massage vibration device can be purchased in the market. The miniature massage vibration device used is an implantable miniature vibration motor. The motor that can be referred to in the market is a miniature vibration motor wrapped with a plastic shell, and the total mass is 1 g. The plastic shell has a length of 13.4 mm, a width of 5.6 mm and a height of 5 mm. The inner motor has a diameter of 4 mm. The suitable voltage is 3V-3.7V, and the current is 100mA. In specific use, the vibration mode, intensity, frequency and time of the massage vibration device are adjusted according to the expansion site, tolerance and expected time of the patient, so that the best expansion effect is obtained.
[0033] The miniature massage vibration device in the embodiment can transmit the massage mode, frequency, intensity and time of the day to the mobile phone app or computer terminal in real time, and the patient and the medical staff can synchronously and dynamically monitor the change of the pressure in the expansion bag before and after treatment. Thus, the vibration scheme can be adjusted, and the efficiency of skin regeneration is improved.
[0034] The pressure sensor (not shown in the figure) is further arranged in the embodiment. The pressure sensor uses a film sensor (i.e. a flexible pressure sensor, commercially available) attached to the surface of the massage vibration device. The effect of skin regeneration is indirectly judged by sensing the pressure change after vibration massage.
[0035] The pressure wireless transmission system composed of the mobile phone terminal is taken as an example in the embodiment. The APP is an application program which can be operated based on the mobile phone terminal and remotely controlled through the mobile phone. Therefore, the mobile phone terminal can receive the massage vibration treatment data of the skin and the change of the pressure in the expansion bag before and after treatment, and the change of the data of the pressure sensor, so that the effect state of the expansion treatment of the skin surface can be judged, and the tension of the skin can be monitored in real time. According to the program setting of the APP, the patient is reminded to perform massage treatment every day.
[0036] The wireless communication mode in the present application can adopt the existing relatively mature signal transmission methods, such as WIFI, Bluetooth, 3G / 4G / 5G, 6LoWPAN, LoRa, ZigBee or other wireless signal transmission modes.
[0037] In order to save the space of the water injection bottle 12, the power supply module of the wireless data transmitter can be a rechargeable thin film power source or a lithium battery. The power supply mode can be solar energy, or the mechanical energy collected from human body heat or human body movement is used to power the electronic monitoring system, or the battery powering the system is recharged. Therefore, according to the process at the time of manufacture, the wireless data transmitter and the power supply module can not be arranged in the water injection bottle, that is, they are directly integrated on the micro massage vibrator 14.
[0038] The shape of the expansion balloon 11 is generally circular or elliptical, which can be arranged by those skilled in the art as needed, which belongs to the content of the prior art. Those skilled in the art can decide whether to set a bacteriostatic coating according to the need. The bacteriostatic coating is an antibiotic coating or is made of nano-silver or nano-zinc, which can effectively prevent the occurrence of infection or inflammation and other diseases. In this embodiment, no antibiotic coating is arranged on the outer surface of the expansion balloon 1.
[0039] The above-mentioned water injection bottle 12 includes a shell 121, and a water injection bowl 122 arranged in the shell 121; the water injection bowl 122 has a hollow cavity 123 inside, and the catheter 13 passes through the shell 121 of the water injection bottle 12 and is connected with the hollow cavity 123 of the water injection bowl 122, so as to complete the water injection operation.
[0040] When the expander is applied to the skin expansion of the forearm, we will adjust the vibration mode, intensity, frequency and time of the massage vibration device according to the skin condition, tolerance and expected time of the patient, significantly accelerate the skin growth rate in the early and middle stages of expansion, shorten the expansion time from 6-12 months to 3 months, and reduce the vibration intensity in the late stage to reduce the symptoms of nerve compression of the expander on the forearm; at the same time, the flexible pressure sensor on the surface of the massage vibration device will monitor the pressure in the balloon of the expander in real time, which can indirectly reflect the regeneration speed of the skin, provide a basis for judging the effect of skin regeneration, realize flexible adjustment of the related parameters of the vibration device, thereby reduce the occurrence of related complications, and provide a basis for ending the expansion in the late stage of expansion, further ensure the safety and reliability of the rapid growth of the expanded skin.
[0041] The skin soft tissue expander of the present application can massage through vibration, which can shorten the time of skin expansion, reduce the pain after the expander is filled with water, reduce the discomfort of nerve compression during expansion, and control the massage mode. If a mobile phone app is used, the massage time and cycle can be remotely controlled by the doctor. Patients and doctors can be reminded whether they have forgotten to massage, and two-way monitoring is achieved.
[0042] The above merely describes the preferred embodiments of the present application and is not intended to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
