Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of muscle detection at the thoracic outlet, in particular to an electromyographic needle fixing bracket for electromyographic detection. Background Art
[0002] The purpose of thoracic outlet scalene muscle electromyography is to evaluate and record the electrical activity of the scalene muscles at the thoracic outlet to understand their function and activity level at the thoracic outlet. The scalene muscles at the thoracic outlet are located on the side of the upper thorax, forming a triangular area between the cervical spine and the first rib, which is called the thoracic outlet. Its main function is to lift and stabilize the scapula and maintain the normal position and posture of the upper limbs during exercise.
[0003] Through electromyography of the scalene muscles at the thoracic outlet, the electrical activity of the scalene muscles at the thoracic outlet can be monitored in real time, and the following information can be obtained: Evaluate the activity of the scalene muscles at the thoracic outlet: By recording the electrical activity of the scalene muscles at the thoracic outlet, it is possible to understand the activity of the scalene muscles at the thoracic outlet during a specific action or task. This helps to determine the strength of the scalene muscles at the thoracic outlet and their effect on the stability of the scapula.
[0004] Evaluate shoulder and neck muscle coordination: The scalene muscles at the thoracic outlet are important participants in other shoulder and neck muscles. They work together with other muscles of the thoracic cavity to complete complex upper limb movements. Through electromyography of the scalene muscles at the thoracic outlet, the coordination and cooperation between the scalene muscles at the thoracic outlet and other muscles of the thoracic cavity can be studied and evaluated.
[0005] Currently, when performing electromyography testing on the scalene muscles of a person's neck, it is necessary to insert an electromyography needle into the person's neck, and during the insertion process, it is necessary to ensure that the electromyography needle is inserted to an appropriate depth. After insertion, when performing the test, the person is required to exert force on the scalene muscles of the neck, which requires the person's head to move. Currently, the electromyography needle is generally held by a doctor, and the doctor also needs to manually adjust the voltage, which increases the difficulty of operation for the person. When the person moves his head, since the doctor cannot move with the person's head, the insertion depth of the electromyography needle may change, which affects the health of the person and also affects the accuracy of the test. Utility Model Content
[0006] The utility model aims to solve the problem in the prior art that the doctor holding the electromyography needle affects the detection efficiency and causes the insertion depth of the electromyography needle to change, and proposes an electromyography needle fixing bracket for electromyography detection.
[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:
[0008] An electromyographic needle fixing bracket for electromyographic detection comprises an ear hook, and a soft pad is fixedly connected to the inner wall of the ear hook;
[0009] The inner wall of the ear hook is fixedly connected with a tightening mechanism, the bottom of the ear hook is fixedly connected with a rotating sleeve, the inner wall of the rotating sleeve is rotatably connected with a rotating head, the bottom of the rotating head is fixedly connected with a slide, the inner wall of the slide is slidably connected with a sliding frame, the side wall of the sliding frame is rotatably connected with a bidirectional threaded rod, the outer wall of the bidirectional threaded rod is rotatably connected with a fixing plate, the bottom of the fixing plate is fixedly connected with a placing ring, and the outer wall of the bidirectional threaded rod is threadedly connected with a clamping mechanism.
[0010] In order to stably hang the bracket on the ear of a person, preferably, the clamping mechanism includes a damping rod fixedly connected to the bottom of the inner wall of the ear hook, the outer wall of the damping rod is sleeved with a clamping spring, and one end of the clamping spring is fixedly connected to a clamping plate.
[0011] In order to stably clamp the electromyographic needle, preferably, the clamping mechanism includes two movable plates threadedly connected to the bidirectional threaded rod, adjacent sides of the two movable plates are fixedly connected with clamping springs, adjacent ends of the clamping springs are fixedly connected with clamping rings, one side of one movable plate on which the clamping spring is installed is fixedly connected with a sliding rod, and the other side of the movable plate on which the clamping spring is installed is fixedly connected with a sleeve.
[0012] In order to ensure stable rotation of the bidirectional threaded rod, further, the bidirectional threaded rod passes through one side of the slide frame and extends to the inner wall of the slide frame, and the outer wall and end of the bidirectional threaded rod are rotatably connected to the slide frame.
[0013] Furthermore, one end of the damping rod away from the ear hook is fixedly connected to one side of the abutment plate on which a holding spring is installed, and one end of the holding spring away from the abutment plate is fixedly connected to the ear hook.
[0014] Furthermore, the sleeve passes through the fixing plate and is slidably connected to the fixing plate.
[0015] Furthermore, the outer side wall of the sliding rod is slidably connected to the inner side wall of the sleeve.
[0016] Furthermore, a sliding groove is provided in the middle of the placement ring, and the inner side wall of the sliding groove is slidably connected to the two sides of the clamping ring.
[0017] Compared with the prior art, the utility model provides an electromyography needle fixing bracket for electromyography detection, which has the following beneficial effects:
[0018] 1. The electromyography needle fixing bracket is used in conjunction with a rotating sleeve, a rotating head, a placing ring, a fixing plate, a bidirectional threaded rod, a slide and a sliding frame. When a person's head moves, the rotating head will rotate in the rotating sleeve. At the same time, due to the movement of the person's head, the sliding frame will slide on the inner wall of the slide, and at the same time, the placing ring will drive the fixing plate to rotate on the bidirectional threaded rod, thereby achieving multi-directional rotation and movement, ensuring that the insertion depth of the electromyography needle will basically not change when the person's head moves, so that the doctor can adjust the voltage more conveniently and reduce the doctor's operation difficulty.
[0019] 2. The electromyoelectric needle fixing bracket is used in conjunction with a bidirectional threaded rod, a movable plate, a clamping spring, a clamping ring, a sliding rod and a sleeve. When the electromyoelectric needle is fixed, the threaded rod is rotated so that the two movable plates slide inward under the limiting action of the sliding rod and the sleeve, thereby pushing the clamping spring and the clamping ring to slide inward. The electromyoelectric needle is clamped and fixed by the clamping spring and the clamping ring, thereby ensuring the stability of the electromyoelectric needle clamping, and the clamping force is a flexible clamping force, thereby reducing the probability of clamping damage to the electromyoelectric needle.
[0020] The parts not involved in the device are the same as the existing technology or can be implemented by the existing technology. The utility model can achieve multi-directional rotation and movement, ensuring that the insertion depth of the electromyography needle will basically not change when the person's head moves, so that the doctor can adjust the voltage more conveniently and reduce the difficulty of the doctor's operation. The electromyography needle is clamped and fixed by the clamping spring and the clamping ring, which ensures the stability of the electromyography needle clamping, and the clamping force is a flexible clamping force, which reduces the probability of clamping damage to the electromyography needle.

[0029] It should be noted that the arrangement of the soft pad 2 provides good protection for the ears of the personnel, and the arrangement of the rotating sleeve 6 and the rotating head 7 facilitates the sliding frame 8 to rotate in all directions.

[0031] It should be noted that the support plate 5 is made of rubber material and can protect the ears of the person.
