Description
Technical Field
The invention relates to medical equipment for thoracic outlet syndrome, in particular to a flexible surface myoelectric device for thoracic outlet syndrome.
Background
The thoracic outlet, i.e. the thoracic upper opening, refers to the area between the clavicle and the 1 st rib, between the supraclavicular fossa and the armpit, through which the nerve vascular bundles such as brachial plexus, subclavian artery, subclavian vein, etc. pass, which relates to 3 narrow sites, from near to far in order, respectively the oblique muscle gap, the costal lock gap and the pectoral small muscle gap. The most common site of stenosis in clinic is the proximal 1 st stenosis gap, the anterior oblique muscle, the posterior middle oblique muscle, and the medial aspect of the first rib forming the lower boundary. In this space there are brachial plexus trunks and subclavian arteries passing, while subclavian veins pass between the anterior oblique muscle and the subclavian muscle. At the distal end of the oblique muscle gap, the neurovascular bundle enters the 2 nd narrow region, namely the costal lock gap, the front edge of which is one third of the middle part of the clavicle, the rear inner side is the first rib, and the rear outer side is formed by the upper edge of the scapula. Finally, the nerve vascular bundle enters the 3 rd narrow gap, the deep portion of the pectoral small muscle tendon, the subcoracoid region below the coracoid process of the scapula, i.e., the pectoral small muscle gap. The thoracic outlet is from the supraclavicular fossa of the outer neck of the human body to the axillary region of the shoulder with up to 16 direct and indirect muscle groups (anterior, middle, posterior oblique, costovertensin, intercostal, pectoral small, sternocleidomastoid, levator scapular, hyoid, subscapular, coracoid, anterior saw, biceps longhead, platykurtic, trapezius, digastric), with up to 22 sensory and motor nerves involved (neck 5-neck 8, thoracic, diaphragmatic, collateral, dorsal scapular, suprascapular, subscapular, lateral, pectoral, longus, dorsal, intercostal, axillary, mydrical, median, radial, ulnar, medial brachial).
The thoracic outlet syndrome (Thoracic outlet syndrome, TOS), i.e., the brachial plexus, subclavian and subclavian veins, takes shape from the supraclavicular fossa to the axillary region, these nerves/vessels may become pinched or stimulated for various reasons, causing symptoms characterized by pain, numbness, weakness, paresthesia or ischemia, and congestion in the upper extremities and neck and shoulders, which was called the Thoracic Outlet Syndrome (TOS) by foreign scholars Peet in 1956. It is classified into a nerve type (neurogenic TOS), an artery type (arterial TOS), a vein type (venosus) according to the pressed structure, wherein the nerve type is considered to account for 95% to 98%, and the best hair site thereof is the oblique muscle gap, followed by the costal lock gap and the pectoral small muscle gap. The nerve type thoracic outlet syndrome (neurogenic Thoracic outlet syndrome nTOS) is mainly clinically represented by a series of clinical manifestations including pain of upper limbs on the same side, hypoesthesia, discomfort of shoulders and necks and the like, the arm plexus is stressed or stimulated, the sick population is mainly aged 20 to 80 years, nTOS is divided into true nTOS and nonspecific nTOS according to whether objective compression evidence is found, the former refers to an objective structure capable of finding nerve clamping pressure, which accounts for about 1% of nTOS, and the latter refers to an objective evidence which does not find clamping structure in spite of pain symptoms caused by arm plexus clamping pressure, which accounts for about 99% of nTOS.
NTOS are mainly dependent on clinical manifestations, and these symptoms and signs are subjective, lack of specificity, and are all manifested after 6 months to 1 year of disease course, while the compression mechanism of the brachial plexus walking in the thoracic outlet area is more complex than that of other peripheral nerves, 3 anatomical gaps at the thoracic outlet are likely to participate in compression of the brachial plexus, the spatial volume of the 3 gaps is influenced by movements of the neck, the shoulder and the upper limb, so that symptoms and signs are atypical, pain or numbness parts are also related to neck, shoulder, upper limb, chest, armpit and shoulder circumference, especially early symptoms, very similar to cervical vertebra and perishoulder diseases, so that a significant part of nTOS patients have misdiagnosis and even cervical vertebra surgery treatment in actual clinical work, poor effect, continuous existence of pain, and some pain aggravation.
How to distinguish the pain symptoms of neck, shoulder and upper limbs at early stage is derived from the relevant factors of the thoracic outlet, which is a great difficulty in the spinal surgery, hand surgery, rehabilitation and pain department, and is a hot spot for competitive researches of a plurality of students at home and abroad in recent years. Therefore, the method has important significance for accurately evaluating nTOS patients, diagnosing early and effectively treating rehabilitation, and for patients, families and society. The nTOS auxiliary examination method is imaging examination and neuro-electrophysiology examination.
The imaging examination of cervical vertebra X-ray, CT, MRI, ultrasound and the like is to observe whether abnormal anatomical structures such as cervical rib, old 1 st rib or collarbone fracture, 1 st rib abnormal running, 7 th cervical vertebra transverse process overlong or too thick, hematoma, tumor, abnormal hyperplasia lymph and connective tissue are observed, and the scope of the diagnostic function and the examination of the authenticity nTOS is mainly played.
Currently, in the clinical examination of nerve electrophysiology, electromyography (EMG), nerve Conduction Velocity (NCV), nerve electrogram and F reaction are used, and the muscle innervated by the upper limb brachial plexus is examined by a needle electrode according to a conventional method, so that the muscle innervated by the median nerve, ulnar nerve and radial nerve related to the brachial plexus at the position of the brachial plexus trunk at the position of the thoracic outlet cannot be accurately reflected, whether the brachial plexus and other branches at the position of the thoracic outlet are abnormal or not, and the information of the related muscle group at the position of the thoracic outlet cannot be reflected, so that the electromyogram is normal in most patients, and the conduction disorder of the medial forearm nerve can be detected in a small number.
Diagnostic local occlusion is the injection of an occluding drug into the narrow space of a suspected site of entrapment, where ultrasound guided oblique intramuscular injection is the most used and studied diagnostic tool for quality nTOS. The pain of the patient is reduced or eliminated after the blocking treatment, which is positive, and the anterior and the middle oblique muscles are suggested to be probably responsible for nTOS. However, when the compression factor is other, diagnosis cannot be completely excluded based on the negative result of the occlusion alone. If myoelectricity detection and diagnostic partial closure can be combined for judgment, NTOS can be more conveniently screened.
When myoelectric detection and diagnostic local occlusion are combined for judgment, the judgment is mainly carried out by the change condition of the myoelectric signal after the occlusion drug is injected. In the prior art, a flexible surface electromyographic device for collecting electromyographic signals is stuck on the surface of skin, the situation of the electromyographic signals is displayed by a terminal after the signals are collected, medical staff can only judge through the electromyographic signals displayed by the terminal, the electromyographic signals of a region are collected by the flexible surface electromyographic device, the medical staff can not conveniently correspond the electromyographic signals to specific positions, and only the stuck part of the flexible surface electromyographic device can be judged as a whole; moreover, when the electromyographic signals change, medical staff cannot intuitively know which parts have obvious electromyographic signal changes, and the electromyographic signal topography displayed by the terminal cannot be accurately corresponding to the acquisition parts.

Wherein the elastic connection portion 21 of the substrate layer extends along the plane direction of the substrate layer 111 in a wavy manner to be elastically connected between the substrate layers 111; the elastic connection portion 21 of the base material layer is integrally formed with the base material layer 111, and is made of an insulating material, preferably a transparent material.
The third lead layer connection portion 22 extends along the plane direction of the third patterned lead layer 113 in a wavy manner and is elastically connected between the third patterned lead layers 113; the third lead layer connection portion 22 enables the third patterned lead layers 113 in the electrode portions 10 to be conducted with each other, so that the surface electromyographic signals detected by the electrode rings 112 can be transmitted outwards.
The second insulating connection parts 23 extend in a wavy manner along the plane direction of the second insulating layers 127 and are elastically connected between the second insulating layers 127; the second insulating connecting portion 23 and the second insulating layer 127 are integrally formed, and each of them is made of an insulating material.
The second lead layer connection portion 24 extends along the plane direction of the second patterned lead layer 125 in a wavy manner and is elastically connected between the second patterned lead layers 125; the second lead layer connection part 24 makes the second patterned lead layers 125 in the respective electrode parts 10 conductive to each other so as to provide a control signal to the second electrode layer 122 of the respective display units 12.
The first insulation connection portion 25 extends along the plane direction of the first insulation layer 126 in a wavy manner and is elastically connected between the first insulation layers 126; the first insulating connecting portion 25 and the first insulating layer 126 are integrally formed, and each of them is made of an insulating material.
The first lead layer connection portion 26 extends along the planar direction of the first patterned lead layer 124 in a wavy manner to be elastically connected between the first patterned lead layers 124. The first lead layer connection portion 26 makes the first patterned lead layer 124 in each electrode portion 10 conductive to each other so as to provide a control signal to the first electrode layer 121 of each display unit 12.
In addition, for convenience of connection, the flexible surface myoelectric device is further provided with a first connection terminal 31 and a second connection terminal 32, wherein the first connection terminal 31 is connected with the elastic connection part 20 outside the electrode part 10 located at one side thereof, and the second connection terminal 32 is connected with the elastic connection part 20 outside the electrode part 10 located at the adjacent side thereof. The first connection terminal 31 and the second connection terminal 32 are provided with a plurality of pins, and the pins are connected with the third lead layer connection part 22, the second lead layer connection part 24 and the first lead layer connection part 26 in the elastic connection part 20, and are used for transmitting electric signals.
Thus, the flexible surface myoelectric device of the present invention is formed. In use, the elastic connection part 20 is stretched to adhere the electrode part 10 to the surface of the human body part to be detected, and then the first connection terminal 31 and the second connection terminal 32 are connected with the matched terminals. The electrode ring 112 in the electrode part 10 may detect surface myoelectricity of a human body, and the detected surface myoelectricity may transmit an electric signal to a mating terminal through the third patterned lead layer 113 and the third lead layer connection part 22 in the elastic connection part 20. The control module in the terminal may process the signal, and then send a control signal to the display unit 12 in the electrode portion 10, and control the display unit 12 of the corresponding electrode portion 10 to graphically display the current surface electromyographic signals, for example, indicate the intensity or change of different electromyographic signals with different colors, etc.
When the device is used for detecting the chest cavity outlet syndrome, the flexible surface electromyographic device is firstly stuck on the skin surface of the suspected clamping and pressing part, and the surface electromyographic signal condition of each part can be displayed in real time through the display unit 12. When the local sealing medicine is injected into the clamping and pressing part, if the surface electromyographic signals at the corresponding positions are obviously changed, medical staff can observe the change of the electromyographic signals in real time through the display unit 12 in the electrode part 10, so that preliminary judgment can be made through the change condition of the electromyographic signals to assist in diagnosing the chest outlet syndrome. Because the display of the display unit 12 can change in real time along with the myoelectric signals detected by the myoelectric unit 11, medical staff can more intuitively judge which positions have obvious myoelectric signal changes and are abnormal, compared with the situation that the myoelectric signals can only be displayed through a terminal, the invention is more favorable for the medical staff to intuitively observe and make more accurate judgment on the situation of each position.
Although the present invention has been disclosed by the above embodiments, the scope of the present invention is not limited thereto, and each of the above components may be replaced with similar or equivalent elements known to those skilled in the art without departing from the spirit of the present invention.
