Description
Technical Field
The invention relates to medical equipment for thoracic outlet syndrome, in particular to a muscle information detection 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).
Thoracic outlet syndrome (Thoracic outlet syndrome, TOS), i.e., the brachial plexus, subclavian and subclavian veins, take shape from the supraclavicular fossa to the axillary region, these nerves/vessels may become pinched or stimulated for a variety of reasons, causing symptoms characterized by pain, numbness, weakness, paresthesia or acroischemia in the upper extremities and shoulders, and siltation, which was called the Thoracic Outlet Syndrome (TOS) by the foreign school student Peet in 1956. It is classified into a nerve Type (TOS), an arterial Type (TOS), a venous type (venosus) according to the compression structure, wherein the nerve type is considered to account for 95% to 98%, and the best hair sites thereof are 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, etc. the patients are mainly 20 to 80 years old, and according to whether objective compression evidence is found, the nTOS is divided into true nTOS and nonspecific nTOS, the former refers to an objective structure capable of finding nerve entrapment, the latter refers to an objective evidence that pain symptoms caused by the arm cluster entrapment are not found, and the latter refers to an objective evidence of no entrapment structure, which is about 99% of nTOS.
The diagnosis of nTOS mainly depends on clinical manifestations, and these symptoms and signs are subjective, lack of specificity, and the clinical signs such as partial muscular atrophy can only be expressed after the course of disease is 6 months to 1 year, meanwhile, the compression mechanism of brachial plexus which walks in the thoracic outlet area is more complex compared with other peripheral nerve compression, 3 anatomical gaps at the thoracic outlet are likely to participate in the compression of brachial plexus, the space volume of 3 gaps is influenced by the movements of neck, shoulder and upper limb, so that the symptoms and signs are atypical, pain or numbness parts also relate to neck, shoulder, upper limb, even chest, armpit and shoulder week, especially early symptoms, are very similar to cervical vertebra and perishoulder diseases, so that a significant part of nTOS patients are misdiagnosed in actual clinical work and even undergo cervical vertebra surgery treatment, the effect is poor, pain persists, and even pain aggravates.
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 accurate assessment, early diagnosis and effective rehabilitation treatment of the nTOS patient, and is of great significance to the patient, the family of the patient and the society. Methods of the antos-assisted examination include imaging examination and neuro-electrophysiological examination.
The imaging examination of cervical vertebra X-ray, CT, MRI, ultrasonic and the like is to observe 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, and mainly plays an exclusive diagnosis role and examines the range of true nTOS.
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, which can be used as a diagnostic tool for the qualitative analysis of antos. The pain of the patients is reduced or eliminated after the blocking treatment, which is positive, and the oblique muscle before and during the blocking treatment is suggested to be the cause of nTOS. However, when the compression factor is other, diagnosis cannot be completely excluded based on the negative result of the occlusion alone.
More and more clinicians recognize that there is a lack of an objective auxiliary detection device for the NTOS to facilitate screening or auxiliary screening of the NTOS.

As shown in fig. 1 to 6, the muscular information detecting apparatus for thoracic outlet syndrome of the present invention includes a plurality of detecting units 10 and electrode needles 20.
The detecting units 10 are distributed in an array, and the detecting units 10 are connected through elastic parts 30, so that a plurality of detecting units 10 and a plurality of elastic parts 30 are connected together to form a detecting main body. Since the detecting units 10 are connected by the elastic parts 30, the shape of the detecting body can be adjusted by stretching the elastic parts 30 so as to be attached to the surface of the part related to the chest outlet syndrome for signal acquisition in use. In this way, the size of the bonding surface can be adjusted according to actual needs, and each detection unit 10 is arranged at an accurate position for detection, so that the accuracy of data acquisition is improved.
The detection unit 10 is provided with an myoelectricity detection unit 11 and a myosound detection unit 12 which are stacked in the thickness direction. The myoelectricity detection part 11 is used for detecting surface myoelectricity signals, and the myosound detection part 12 is used for detecting myosound signals. By collecting the surface electromyographic signals and the myotone signals, whether the muscles related to the chest outlet syndrome are abnormal or not can be primarily judged.
The electrode needle 20 is configured in the form of a syringe having a needle tip 21 insertable into the body. A microelectrode array is provided on the tip portion 21, so that the electrode needle 20 can be used for both injection of a drug and insertion into the body to collect excitation signals of a muscle movement unit in the body. The microelectrode array may be arranged with reference to known techniques, and the invention is not limited thereto.
In order to facilitate the use of the electrode needle 20, the electrode needle 20 is inserted into the suspected clamping part, and the insertion holes 17 penetrating through the myotone detection part 12 and the myoelectricity detection part 11 are arranged on each detection unit 10. The insertion hole 17 is used for inserting the electrode needle 20. After the surface electromyographic signals and the myoacoustic signals are collected by the detection unit 10, the abnormal position of the suspicious clamping part can be judged according to the surface electromyographic signals and the myoacoustic signals, so that the electrode needle 20 can be inserted into the narrow gap 19 of the suspicious clamping part through the detection unit 10 at the corresponding position to inject the local sealing medicine, and whether the patient is the chest outlet syndrome can be further judged through the local sealing diagnosis. When the local closed medicine is injected into the narrow gap 19 of the suspected clamping part, the corresponding pain can disappear if the chest outlet syndrome is caused; if the symptom is not the chest outlet syndrome, the user feel change is not obvious before and after the medicine injection; the excitation signals of the muscle movement units after the local closed medicine is injected are collected through the microelectrode array real-time array of the electrode needle 20, so that the muscle change state after the medicine is injected can be judged, and the effect of the closed medicine injection is judged to identify the chest outlet syndrome. In addition, in this process, the detection unit 10 collects the surface myoelectric signals and the myosound signals in real time, and can also be used for further study and diagnosis.

In other words, the inner electrode 113 and the outer electrode 112 are disposed on two opposite sides of the substrate layer 111. The inner electrode 113 is electrically connected to the outer electrode 112 and forms a through cavity 114 in the first through hole 1113.
In use, the outer electrode 112 is in contact with the skin and an electrical signal flows from the outer electrode 112 to the inner electrode 113, so that it can be led out from one side of the inner electrode 113.
Further, a first insulating layer 13 is provided between the myoelectricity detection unit 11 and the myosound detection unit 12. The first insulating layer 13 is used for insulating and isolating the myoelectricity detection part 11 and the myosound detection part 12.

The connecting post 123 is connected to the edges of the polar plate layer 121 and the diaphragm layer 122. The connecting post 123 supports the edge of the diaphragm layer 122, so that the middle of the diaphragm layer 122 is in a suspended state. When the sound causes the air sound pressure change, air can enter between the polar plate layer 121 and the vibrating diaphragm layer 122, so that the vibrating diaphragm layer 122 vibrates under the action of the air pressure or the sound pressure, the capacitance of a capacitance structure formed by the polar plate layer 121 and the vibrating diaphragm layer 122 changes, and further the detection of sound waves is realized, and muscle sound signals are collected.

The wiring arrangement of the electrode leads can be referred to the wiring arrangement of the flexible circuit board, and can lead out the electrical signals of the inner electrodes 113. Through the patterned electrode lead layer 115, the electrical signals of each detection unit 10 can be led out individually for data analysis, so that the abnormal condition of the muscle can be more accurately judged.
The fifth through hole 1151 is located opposite to the vent chamber 114, and its center line coincides. The fifth through hole 1151 has a diameter identical to that of the second through hole 131.

The first sound hole 1152, the second sound hole 132, and the third sound hole 1212 are located opposite to each other and penetrate the gap 19, so that a muscle sound signal can enter the muscle sound detecting unit 12 through the gap 19, the first sound hole 1152, the second sound hole 132, and the third sound hole 1212 in order, and further cause the diaphragm layer 122 to vibrate to cause a capacitance change, so that the muscle sound signal is collected by the muscle sound detecting unit 12.
The first sound holes 1152, the second sound holes 132, and the third sound holes 1212 are distributed in the periphery of the jack 17 in an array along the circumferential direction of the jack 17, and correspond to the position between the second cylinder 162 and the vent chamber 114, so as to communicate with the gap 19.
