Abstract
Description
Technical Field
[0001] This invention relates to the field of nerve localization technology, and in particular to a localization system and control method for superficial points of the common peroneal nerve. Background Technology
[0002] When performing nerve conduction testing, stimulation electrodes and recording electrodes need to be placed at different locations along the entire length of the nerve. The nerve is stimulated by the stimulation electrodes, and the nerve potential at that point is obtained by the recording electrodes. However, due to various physiological changes such as limb edema, local skin thickening, obesity, and age, it is sometimes difficult to obtain nerve locations, especially for nerve conduction testing of the common peroneal nerve. Since the common peroneal nerve is located in the lower limb, and edema often occurs in the lower limb, it is usually necessary to find a superficial point of the common peroneal nerve when placing recording electrodes. The process of finding a superficial point of the common peroneal nerve often requires several attempts to place and stimulate the electrodes, which is very inconvenient. Summary of the Invention
[0003] To address the aforementioned technical problems, this invention provides a localization system and control method for superficial points of the common peroneal nerve, the specific technical solution of which is as follows:
[0004] A localization system for superficial points of the common peroneal nerve includes:
[0005] An electrical stimulation unit is attached to the surface of the body at a position relative to the end of the common peroneal nerve.
[0006] The electrical extraction unit is used to attach to the nerve trunk of the common peroneal nerve on the surface of the human body;
[0007] An electrochromic unit is attached to and covers the electrical lead-out unit;
[0008] An image acquisition unit is used to acquire an image of the electrochromic unit;
[0009] The judgment unit, connected to the image acquisition unit, is used to judge the color change of the image of the electrochromic unit and mark a preset number of color change points on the image of the electrochromic unit according to the depth of the color change from dark to light. The color change points are the superficial points of the common peroneal nerve.
[0010] Preferably, the electrical lead-out unit comprises a conductive metal film.
[0011] Preferably, the electrochromic unit comprises:
[0012] An ion storage layer is attached to the outer layer of the conductive metal film;
[0013] The electrolyte layer is attached to the outer layer of the ion storage layer;
[0014] An electrochromic layer is attached to the outer layer of the electrolyte layer;
[0015] A transparent conductive layer is attached to the outer layer of the electrochromic layer.
[0016] Preferably, the electrochromic layer is made of an electrochromic material, which includes one or more of tungsten trioxide, polythiophene and its derivatives, violetin, tetrathiofulvalene, and metal phthalocyanine compounds.
[0017] Preferably, the electrical stimulation unit includes a positive electrode and a negative electrode, and the negative electrode of the electrical stimulation unit is disposed adjacent to the electrical lead-out unit.
[0018] Preferably, the image acquisition unit includes a camera, the judgment unit includes a processor, and the camera is electrically connected to the processor.
[0019] Preferably, the system further includes a control unit connected to the judgment unit, which is used to input the electrical stimulation intensity, electrical stimulation duration, radial size of the color change point, and number of color change points.
[0020] Preferably, it further includes a display unit, which is connected to the judgment unit and is used to display an electrochromic unit image marked with the color change points.
[0021] The present invention also provides a control method for controlling a localization system for superficial points of the common peroneal nerve as described in any of the above claims, the control method comprising the following steps:
[0022] Electrical stimulation intensity setting;
[0023] Electrical stimulation duration setting;
[0024] Setting the radial size of the color change point;
[0025] The number of color change points can be set.
[0026] Preferably:
[0027] The intensity of the electrical stimulation is 100–400 mV;
[0028] The duration of the electrical stimulation is 0.05–1.0 ms;
[0029] The radial size of the color change point is 5–20 mm;
[0030] The number of color change points is 1 to 5;
[0031] The initial color of the electrochromic unit is white.
[0032] The present invention provides a positioning system for superficial points of the common peroneal nerve. By setting an electrical stimulation unit on the human body surface relative to the end of the common peroneal nerve and an electrical extraction unit on the human body surface relative to the nerve trunk of the common peroneal nerve, and covering and attaching an electrochromic unit to the electrical extraction unit, the current after the electrical stimulation unit stimulates the common peroneal nerve can be extracted through the superficial point by the electrical extraction unit, causing the electrochromic unit to produce a color change.

[0044] Please see Figure 1 and Figure 2 This embodiment provides a localization system for superficial points of the common peroneal nerve, including an electrical stimulation unit 1, an electrical extraction unit 2, an electrochromic unit 3, an image acquisition unit 4, and a judgment unit 5.
[0045] The electrical stimulation unit 1 is used to attach to the surface of the human body at a position relative to the end of the common peroneal nerve.
[0046] The electrical extraction unit 2 is used to attach to the nerve trunk of the common peroneal nerve on the surface of the human body.
[0047] Electrochromic unit 3 is wrapped and bonded to electrical lead unit 2.
[0048] Image acquisition unit 4 is used to acquire images from electrochromic unit 3.
[0049] The judgment unit 5 is connected to the image acquisition unit 4 and is used to judge the color change of the image of the electrochromic unit 3 and mark a preset number of color change points on the image of the electrochromic unit 3 according to the depth of the color change from dark to light. These color change points are the superficial points of the common peroneal nerve.
[0050] The electrostimulation unit 1 provides electrical stimulation to the common peroneal nerve. The current travels through the nerve trunk and is extracted by the electro-extraction unit 2 through human tissue. However, the current is difficult to extract from the nerve when it is deep within the body surface, similar to the nerve conduction detection process. After the nerve potential is extracted, the electrochromic unit 3 produces a color change. The closer the nerve is to the body surface, the less human tissue there is at that point, resulting in a larger extracted current and a deeper color change in the electrochromic unit 3, and vice versa. Therefore, the color change of the electrochromic unit 3 can be observed to determine the nerve potential. The peroneal nerve superficial point is severed, but because the current drawn out by the electrical extraction unit 2 is small, the color change produced by the electrochromic unit 3 is difficult to observe with the naked eye. Therefore, the image of the electrochromic unit 3 after color change can be obtained by the image acquisition unit 4, and the color change area of the electrochromic unit 3 can be judged by the judgment unit 5 and the color change part can be marked. Then, according to the color change depth, the point with the largest color change is marked on the image of the electrochromic unit 3 according to a preset number, so that the operator can easily obtain the location point of the peroneal nerve superficial point.
[0051] The positioning system for superficial points of the common peroneal nerve provided in this embodiment involves setting an electrical stimulation unit 1 on the surface of the body relative to the end of the common peroneal nerve, setting an electrical extraction unit 2 on the surface of the body relative to the nerve trunk of the common peroneal nerve, and covering and attaching an electrochromic unit 3 to the electrical extraction unit 2. This allows the current after the electrical stimulation unit 1 stimulates the common peroneal nerve to be extracted through the superficial point by the electrical extraction unit 2, causing the electrochromic unit 3 to produce a color change. The location of the color change is determined by the image acquisition unit 4 and the judgment unit 5 and then marked, making it convenient for operators to locate the superficial points of the common peroneal nerve.
[0052] Furthermore, the electrical extraction unit 2 includes a conductive metal film to facilitate the extraction of nerve potentials.
[0053] Furthermore, the electrochromic unit 3 includes an ion storage layer 31, an electrolyte layer 32, an electrochromic layer 33, and a transparent conductive layer 34.
[0054] The ion storage layer 31 is attached to the outer layer of the conductive metal film.
[0055] Electrolyte layer 32 is attached to the outer layer of ion storage layer 31.
[0056] Electrochromic layer 33 is attached to the outer layer of electrolyte layer 32.
[0057] A transparent conductive layer 34 is attached to the outer layer of the electrochromic layer 33.
[0058] In this embodiment, the transparent conductive layer 34 can be connected to the negative terminal of the power supply. After the conductive metal film extracts the nerve potential, the current can be transferred to the transparent conductive layer 34 through the ion storage layer 31 and the electrolyte layer 32. This allows ions in the ion storage layer 31 to move into the electrochromic layer 33 through the electrolyte layer 32, causing the electrochromic layer 33 to change color. The larger the extracted current, the more obvious the color change of the electrochromic layer 33, and the closer the point is to the nerve. After positioning is completed, the electrical extraction unit 2 and the electrochromic unit 3 can be removed from the human body. The transparent conductive layer 34 is connected to the positive terminal of the power supply, and the electrical extraction unit 2 is connected to the negative terminal of the power supply, allowing the ions to flow back into the ion storage layer 31 for future positioning. The electrochromic layer 33 can be an electrochromic material, which is a conventional technology and will not be described in detail in this embodiment.
[0059] Furthermore, the electrochromic layer 33 is made of an electrochromic material, which includes one or more of tungsten trioxide, polythiophene and its derivatives, violetin, tetrathiofulvalene, and metal phthalocyanine compounds.
[0060] Furthermore, the electrical stimulation unit 1 includes a positive electrode and a negative electrode. The negative electrode of the electrical stimulation unit 1 is located near the electrical lead-out unit 2 to prevent the positive electrode from blocking current conduction.
[0061] Furthermore, the image acquisition unit 4 includes a camera, and the judgment unit 5 includes a processor. The camera is electrically connected to the processor so that after the camera acquires the image of the electrochromic unit 3 after the color change, the processor can judge the color change.
[0062] Furthermore, it also includes a control unit 6, which is connected to the judgment unit 5 and is used to input the electrical stimulation intensity, electrical stimulation duration, radial size of the color change point, and number of color change points, so that the judgment unit 5 can mark a preset number and preset radial size of color change points on the image of the electrochromic unit 3.
[0063] Furthermore, it also includes a display unit 7, which is connected to the judgment unit 5. The display unit 7 can be a display screen, which is used to display an electrochromic unit image marked with color change points.
[0064] This embodiment also provides a control method for controlling a localization system for superficial points of the common peroneal nerve as described in any of the above embodiments, the control method comprising the following steps:
[0065] Electrical stimulation intensity setting.
[0066] Electrical stimulation duration setting.
[0067] The radial size of the color change point is set.
[0068] The number of color change points can be set.
[0069] The above values can be input into the judgment unit 5 through the control unit 6.
[0070] Furthermore, in the embodiments provided in this implementation:
[0071] The electrical stimulation intensity is 100–400 mV.
[0072] The duration of electrical stimulation is 0.05–1.0 ms.
[0073] The radial size of the color change point is 5–20 mm.
[0074] The number of color change points ranges from 1 to 5.
[0075] The initial color of the electrochromic unit 3 is white, so as to facilitate the determination of the color change of the electrochromic unit 3.
[0076] Working principle:
[0077] Electrical stimulation unit 1 can provide electrical stimulation to the common peroneal nerve. The current can travel through the nerve trunk of the common peroneal nerve and be extracted by the electro-extraction unit 2 through human tissue. However, when the nerve is deep within the human body, the current is difficult to extract, similar to the nerve conduction detection process. After the nerve potential is extracted, the electrochromic unit 3 produces a color change. The closer the nerve is to the human body surface, the less human tissue there is at that point, the greater the extracted current, resulting in a deeper color change in the electrochromic unit 3, and vice versa. Therefore, the color change of the electrochromic unit 3 can be used to determine the common peroneal nerve. The common peroneal nerve is superficial, but because the current drawn out by the electrical extraction unit 2 is small, the color change produced by the electrochromic unit 3 is difficult to observe with the naked eye. Therefore, the image of the electrochromic unit 3 after color change can be acquired by the image acquisition unit 4, and the color change area of the electrochromic unit 3 can be judged by the judgment unit 5 and the color change part can be marked. Then, according to the color change depth, the color change point with the greatest change is marked on the image of the electrochromic unit 3 according to a preset number, so that the operator can easily obtain the location point of the common peroneal nerve superficial point.
