Description

A neurophysiological electromyography examination device Technical Field

[0001] This invention relates to the field of medical device technology, specifically to a neurophysiological electromyography (EMG) examination device. Background Technology

[0002] Electromyography (EMG) is an important neurophysiological diagnostic technique that assesses the functional state of nerves and muscles by recording the electrical activity of muscles in resting and contracted states. This examination typically requires inserting needle electrodes into specific muscle sites to collect and analyze electromyographic signals to aid in the diagnosis of neurogenic or myogenic lesions. In clinical practice, the accuracy and efficiency of EMG examination directly affect the reliability of the diagnosis and the patient's experience.

[0003] Existing electromyography (EMG) devices generally include an instrument, needle electrodes, and associated leads. For example, the Cascade M1 EMG instrument works as follows: the operator manually inserts the needle electrodes into the patient's examination points. The needle electrodes are electrically connected to the instrument via leads, and the instrument collects and processes the electromyographic signals. In terms of connection, the needle electrodes and leads are connected via detachable plugs and interfaces to ensure electrical signal transmission, thereby obtaining the patient's EMG data and enabling the EMG examination.

[0004] During the examination, the operator needs to manually change the insertion position of the needle electrode or replace the needle electrode itself according to the testing requirements. However, in existing devices, operators need to constantly change the needle electrode at the end of the lead wire for different patients; for the same patient, multiple punctures need to be performed at different sites using the needle electrode, which is cumbersome and time-consuming, reducing overall examination efficiency. More seriously, the manual needle replacement process requires direct contact with the used needle electrode, which not only increases the operator's occupational exposure risk but may also cause safety hazards such as cross-infection. Therefore, the fundamental defect of the existing technology is that it is difficult to coordinate the switching of needle electrodes with punctures, which seriously affects the safety and efficiency of the examination process. Therefore, this invention provides a neurophysiological electromyography examination device to solve the above problems. Summary of the Invention

[0005] To address the aforementioned problems, this invention provides a neurophysiological electromyography (EMG) examination device. Through the design of the examination port, the device can store several different types of EMG needles. Through the design of the sliding stage, the position of the EMG needles can be automatically adjusted, allowing different types of EMG needles to be aimed at different locations on the patient. Furthermore, through the design of the sliding column, the puncture of the EMG needles and the transmission of electrical signals are automatically realized. This eliminates the need for medical personnel to repeatedly change and install needle electrodes, thereby improving the safety and efficiency of the examination process.

[0006] To achieve the above objectives, the technical solution of the present invention is as follows: A neurophysiological electromyography (EMG) examination device includes an examination instrument and a placement platform. A sliding groove is formed on the placement platform, and a sliding column is slidably fitted within the sliding groove along its length. A plurality of examination holes are formed on the sliding platform, and a sliding column made of conductive material is vertically slidably fitted within each examination hole. An EMG needle is fixedly connected to the top of each sliding column. A switching component is provided on the side wall of the placement platform for driving the sliding column to slide laterally along the sliding platform. An installation groove is formed inside the placement platform, and the examination holes are all located above the installation groove. An examination component is provided within the installation groove for driving the sliding column to slide vertically along the examination holes.

[0007] The technical principle of the above solution is as follows:

[0008] Align the area where the electromyography (EMG) needle needs to be inserted with the examination hole directly above the mounting slot. The examination component drives the sliding column to move upward along the examination hole, inserting the EMG needle into the designated area. Simultaneously, the examination component, through stable contact, utilizes the conductivity of electricity to conduct the electrical signal received by the EMG needle to the examination device. After the examination of that area is completed, drive the examination component again, which will move the sliding column downward along the examination hole, inserting the EMG needle and automatically removing it from the patient's body. At the same time, the patient can align other areas requiring examination with the examination hole directly above the mounting slot. The switching component will push the sliding stage along the sliding groove, thereby moving all EMG needles synchronously. During this process, the switching component will push the used EMG needle out of the placement stage and simultaneously align the new EMG needle with the examination position. At this point, restarting the examination component will allow for a new examination.

[0009] The above approach has the following beneficial effects:

[0010] 1. In existing technologies, when performing punctures on different parts of a patient's body, medical staff need to constantly change the needle electrodes on the leads, which is cumbersome, inefficient, and the electromyography needles are easily contaminated. This invention, through the design of a sliding stage and examination port, can store a large number of different types of electromyography needles. At the same time, by sliding the stage, it can automatically switch between used and new electromyography needles according to the patient's needs, eliminating the need for manual operation by medical staff, effectively reducing the workload of medical staff and improving work efficiency. It also reduces the risk of electromyography needle contamination and improves the safety of the examination.

[0011] 2. This invention, through the design of a sliding column, can automatically perform puncture and removal of electromyography needles on patients without the need for manual operation by medical staff. At the same time, in conjunction with the switching of electromyography needles, it can automatically remove the used electromyography needle from the patient's body and insert a new electromyography needle into the patient's new examination site, so that the switching and installation of electromyography needles are coordinated and the examination work is automated.

[0012] 3. In existing technologies, needle electrodes and wires are often connected via connectors and interfaces. While this method can achieve signal transmission, it is not very convenient, requiring operators to repeatedly insert and disassemble the needle electrode to connect it to the wire. Furthermore, each needle electrode needs to be equipped with a plug, resulting in high testing costs. This invention, through the design of a sliding column, ensures stable contact between the various components. Utilizing the conductivity of electricity, it can effectively transmit the electrical signals received by the electromyography needle to the testing instrument. This method can effectively improve the stability and effectiveness of electrical signal transmission, reduce signal fluctuations, improve operational convenience, and reduce testing costs.

[0013] Furthermore, the switching component includes a controller and a first electric cylinder fixedly connected to the side wall of the placement platform, the output shaft of the first electric cylinder being fixedly connected to the side wall of the sliding platform; the controller is used to control the operation of the first electric cylinder.

[0014] Beneficial effects: When the first electric cylinder is running, the output shaft of the first electric cylinder will push the sliding table to slide laterally along the sliding groove, thereby adjusting the position of all sliding columns and electromyography needles.

[0015] Furthermore, the inspection component includes a second electrically controlled cylinder fixedly connected to the top wall of the mounting slot, and a pusher made of conductive material fixedly connected to the output shaft of the second electrically controlled cylinder; a number of first holes for the pusher to slide vertically are opened on the sliding slot; the diameter of the first holes is larger than the diameter of the pusher; the pusher is electrically connected to the inspection instrument.

[0016] Beneficial effect: When the second electric cylinder is running, the output shaft of the second electric cylinder will push the push head into the first hole above it, thereby pushing the sliding column and the electromyography needle to slide upward along the examination hole, and then inserting the electromyography needle into the examination position.

[0017] Furthermore, the sliding column is hollow inside, and a second hole is opened at the bottom of the sliding column. The diameter of the second hole is larger than the diameter of the push head, and the diameter of the second hole is smaller than the diameter of the first hole. The push head is equipped with an adjustment component for adjusting the connection state between the push head and the sliding column.

[0018] Beneficial effects: When the pusher slides upward, it will also pass through the second hole and contact the inner top wall of the sliding column, so that the pusher and the sliding column are engaged, realizing the stable transmission of electrical signals. When the pusher slides downward, the pusher will leave the second hole and separate from the sliding column, which makes it easier to switch to a new electromyography needle.

[0019] Furthermore, the adjustment assembly includes several limiting grooves formed on the side wall of the pusher, each of which is laterally slidingly fitted with a limiting ball; each limiting ball is fixedly connected with a spring, and the end of the spring away from the limiting ball is fixedly connected to the inner side wall of the limiting groove; when the sliding column slides along the inspection hole, the resistance to the spring is less than the spring force.

[0020] Beneficial effects: The design of the first and second holes in this scheme allows the electromyography needle to be punctured first, ensuring that the electrical signal is conducted only after the puncture is completed. This method can effectively avoid signal fluctuations caused by the vibration of the electromyography needle during the puncture process, and only collect the effective electrical signal after the signal has stabilized, thereby effectively improving the accuracy of the examination.

[0021] Furthermore, a placement ring is fixedly connected to the placement platform, and a temperature control component for adjusting the temperature of the patient's limb is provided inside the placement ring. A fixing component for fixing the patient's limb is provided at the top of the placement ring.

[0022] Beneficial effects: The placement ring can provide a relatively enclosed space for the patient's limb, reduce the interference of the external environment on the patient's limb, play a certain role in protection and heat preservation, and thus improve the stability of the examination process.

[0023] Furthermore, the fixing assembly includes a piston box fixedly connected to the top of the placement ring, a piston plate vertically slidingly fitted inside the piston box, a piston rod fixedly connected to the bottom of the piston plate, the bottom of the piston rod penetrating the top of the placement ring and fixedly connected to a fixing plate; the piston rod and the placement ring are vertically slidingly fitted; the piston box is provided with a piston assembly for driving the piston plate to slide vertically along the inner sidewall of the piston box.

[0024] Beneficial effects: By adjusting the fixation plate, the device can fix limbs of different sizes, thereby ensuring the stability of puncture and electrical signal acquisition, and thus improving the examination results.

[0025] Furthermore, the piston assembly includes a third electrically controlled cylinder fixedly connected to the top wall inside the piston box, and the output shaft of the third electrically controlled cylinder is fixedly connected to the top of the piston plate; the controller is used to control the operation of the third electrically controlled cylinder.

[0026] Beneficial effects: The output shaft of the third electric cylinder will push the piston plate and piston rod to slide vertically in the piston box, thereby adjusting the position of the fixing plate and realizing the self-adaptive fixation of the limb.

[0027] Furthermore, the temperature control assembly includes several heating elements embedded in the placement ring, and a controller is used to control the operation of the heating elements.

[0028] Beneficial effects: The design of the heating element can effectively regulate the ambient temperature inside the placement ring, thereby ensuring the flow of the patient's blood, improving the acquisition effect of electrical signals, and enhancing the patient's comfort and examination experience.

[0029] Furthermore, flexible layers are symmetrically fixed to the top of the placement platform, with the flexible layers located on both sides of the sliding platform.

[0030] Beneficial effects: The flexible layer can provide flexible support for the patient's limbs, improving the stability and comfort of the limbs; at the same time, the flexible layer can create a certain distance between the patient's limbs and the sliding platform, avoiding obstruction of the sliding platform by the patient's limbs and ensuring that the sliding platform can slide stably along the sliding groove.

[0042] The following detailed description illustrates the specific implementation method:

[0043] Example 1:

[0044] As shown in Figures 1 and 2, a neurophysiological electromyography (EMG) examination device includes an examination instrument (in this embodiment, the examination instrument is a conventional neurophysiological EMG instrument, not shown in the figure) and a placement platform 1. The placement platform 1 has a sliding groove, and a sliding stage 3 is slidably fitted in the sliding groove along its length. The sliding stage 3 has several examination holes, and a sliding column 12 made of conductive material is vertically slidably fitted in each examination hole (in this embodiment, the sliding column 12 is made of aluminum, which is lightweight, low-cost, and has good conductivity). An electromyography needle 13 is fixedly bonded to the top of each sliding column 12.

[0045] As shown in Figure 1, flexible layers 4 are symmetrically fixed and bonded to the top of the placement platform 1 (in this embodiment, the material used to prepare the flexible layers 4 is silicone), and the flexible layers 4 are located on both sides of the sliding platform 3.

[0046] Specifically, as shown in Figure 1, the flexible layer 4 can provide flexible support for the patient's limbs, improving the stability and comfort of the patient's limbs; at the same time, the flexible layer 4 can create a certain distance between the patient's limbs and the sliding platform 3, avoiding obstruction of the sliding platform 3 by the patient's limbs, and ensuring that the sliding platform 3 can slide stably along the sliding groove.

[0047] As shown in Figures 1 and 2, the side wall of the placement platform 1 is provided with a switching assembly for driving the sliding column 12 to slide laterally along the sliding platform 3. The switching assembly includes a controller and a first electric cylinder 2 bolted to the side wall of the placement platform 1. The output shaft of the first electric cylinder 2 is bolted to the side wall of the sliding platform 3. The controller is used to control the operation of the first electric cylinder 2.

[0048] Specifically, as shown in Figure 1, the placement platform 1 can be used to place the patient's limbs, hands, and feet; in this embodiment, an arm examination is used as an example. As shown in Figure 1, the patient inserts their hand into the placement platform 1 from right to left and aligns the examination point (the position where the electromyography needle 13 needs to be inserted) with the examination hole currently located at the right end of the placement platform 1; the medical staff activates the first electric cylinder 2 through the controller, and the output shaft of the first electric cylinder 2 pushes the sliding platform 3 to move to the right in the sliding groove, thereby driving the sliding column 12 and the electromyography needle 13 to move to the right synchronously. When the required electromyography needle 13 is aligned with the examination point, the medical staff pauses the operation of the first electric cylinder 2 through the controller, and can then select the specified electromyography needle 13 to perform targeted puncture at the examination point.

[0049] As shown in Figures 3 and 4, the placement platform 1 has an installation groove, and the inspection holes are all located above the installation groove. An inspection assembly for driving the sliding column 12 to slide vertically along the inspection holes is provided in the installation groove. The inspection assembly includes a second electric cylinder 8 bolted to the top wall of the installation groove. A pusher 9 made of conductive material is bolted to the output shaft of the second electric cylinder 8 (in this embodiment, the pusher 9 is made of stainless steel and doped with copper or other conductive materials as the core, making it durable, low-cost, and with excellent conductivity). Several first holes 101 for the pusher 9 to slide vertically are opened in the sliding groove; the diameter of each first hole 101 is larger than the diameter of the pusher 9; the pusher 9 is electrically connected to the inspection instrument. The sliding column 12 is hollow inside, and a second hole 102 is opened at the bottom of the sliding column 12. The diameter of each second hole 102 is larger than the diameter of the pusher 9 and smaller than the diameter of the first hole 101; an adjustment assembly for adjusting the connection state between the pusher 9 and the sliding column 12 is provided on the pusher 9. The adjustment assembly includes several limiting grooves opened on the side wall of the pusher 9, and each limiting groove is laterally slidingly fitted with a limiting ball 11; each limiting ball 11 is fixedly connected with a spring 10 by screws, and the end of the spring 10 away from the limiting ball 11 is fixedly connected to the inner side wall of the limiting groove by screws; when the sliding column 12 slides along the inspection hole, the resistance to the spring 10 is less than the elastic force of the spring 10.

[0050] Specifically, as shown in Figures 5 and 6, after aligning the designated electromyography needle 13 with the examination point, the medical staff can activate the second electric control cylinder 8. The output shaft of the second electric control cylinder 8 will push the push head 9 into the first hole 101 above it. When the push head 9 enters the first hole 101, since the sliding table 3 and the first hole 101 remain stable in the vertical direction, the limiting ball 11 will slide into the limiting groove under the limiting action of the first hole 101, and the spring 10 will also be compressed accordingly, so that the push head 9 can enter the first hole 101.

[0051] As shown in Figures 5 and 6, since the diameter of the second hole 102 is smaller than the diameter of the first hole 101, when the pusher 9 moves through the first hole 101 into the examination hole, the diameter of the pushing structure formed by the pusher 9 and the limiting ball 11 will be larger than the diameter of the second hole 102. Also, since the resistance of the sliding column 12 to the spring 10 when it slides along the examination hole is less than the elastic force of the spring 10, the spring 10 cannot be compressed. Therefore, the limiting ball 11 will only support the bottom of the sliding column 12, thereby stably pushing the sliding column 12 and the electromyography needle 13 upward, thereby inserting the electromyography needle 13 into the patient's body.

[0052] As shown in Figures 5 and 6, when the electromyography needle 13 is inserted into the patient's body, the sliding column 12 is restricted by the patient's limb and cannot continue to slide upward, making the sliding column 12 and the second hole 102 relatively stable in the vertical direction. At this time, since the position of the sliding column 12 is restricted and remains stationary, the resistance generated by the second hole 102 will overcome the elastic force of the spring 10. The limiting ball 11 will slide into the limiting groove under the limiting action of the second hole 102, and the spring 10 will also be compressed accordingly, so that the push head 9 can enter the second hole 102 and move upward. The top of the push head 9 will make stable contact with the inner top wall of the sliding column 12, thereby realizing the stable transmission of electrical signals.

[0053] This embodiment, through the design of the first hole 101 and the second hole 102, allows the electromyography needle 13 to be punctured first, ensuring that the electrical signal is connected and conducted after the puncture is completed. This method can effectively avoid signal fluctuations caused by the vibration of the electromyography needle 13 during the puncture process, and only collect the effective electrical signal after the connection state is stable, thereby effectively improving the accuracy of the examination.

[0054] As shown in Figures 5 and 6, when the examination at this location is completed and the examination point needs to be changed, the second electric cylinder 8 is restarted via the controller. The output shaft of the second electric cylinder 8 will drive the push head 9 to move downward. At this time, the electromyography needle 13 will remain stable under the clamping action of the patient's muscles. When the push head 9 moves to the second hole 102, the bottom of the spring 10 will contact and engage with the inner bottom wall of the sliding column 12. The push head 9 generates a downward pushing force on the sliding column 12 through the limiting ball 11, thereby driving the sliding column 12 and the electromyography needle 13 to slide downward, making... The electromyography needle 13 is separated from the patient's limb and stored in the examination port after use. When the bottom of the sliding column 12 contacts the top of the first hole 101, the first hole 101 and the second hole 102 remain stable in the vertical direction. At this time, the limiting ball 11 will be limited by the first hole 101 and the second hole 102. The spring 10 is compressed, and the limiting ball 11 retracts into the limiting groove, so that the pusher 9 slides down through the first hole 101 and the second hole 102 into the mounting groove to avoid affecting the subsequent switching of the electromyography needle 13.

[0055] As shown in Figures 1 and 5, after the pusher 9 has retracted, the patient can adjust the position of their limb along the placement platform 1 and align another examination point with the examination hole currently located on the right end of the placement platform 1. At the same time, medical staff can restart the first electric control cylinder 2 to push the sliding platform 3 to slide to the right again, moving the used electromyography needle 13 to the outer right end of the placement platform 1, making it easier for medical staff to replace the used electromyography needle 13 later. The new electromyography needle 13 is then aligned with the current examination point to perform a new examination, effectively avoiding cross-infection and ensuring the safety of the examination.

[0056] This embodiment can automatically switch between different types of electromyography (EMG) needles 13 according to the patient's examination needs. It also enables automatic puncture and removal of the EMG needles 13, with both processes coordinating without interference. No manual operation by medical staff is required, effectively reducing their workload and improving efficiency. Furthermore, it reduces the risk of contamination of the EMG needles 13, enhancing the safety of the examination. Moreover, through improvements in the signal transmission method of the EMG needles 13, this embodiment automates the transmission of electrical signals and collects only the effective electrical signals after needle puncture, significantly improving both the efficiency and quality of the examination.

[0057] Example 2:

[0058] The difference from Embodiment 1 is that, as shown in Figure 1, a placement ring 5 is fixedly bonded to the placement platform 1, and a temperature control component for adjusting the temperature of the patient's limb is provided inside the placement ring 5. The temperature control component includes several heating elements (not shown in the figure; in this embodiment, heating elements are heating wires) embedded in the placement ring 5, and a controller is used to control the operation of the heating wires.

[0059] Specifically, during the examination, the user can insert the limb into the placement ring 5; the placement ring 5 can provide a relatively enclosed placement space for the patient's limb, reduce the interference of the external environment on the patient's limb, play a certain role in protection and heat preservation, and thus improve the stability of the examination process.

[0060] Meanwhile, medical staff can adjust the heating temperature of the heating wire through the controller, thereby effectively regulating the ambient temperature within the placement ring 5, ensuring the flow of the patient's blood, improving the acquisition effect of electrical signals, and enhancing the patient's comfort and examination experience.

[0061] Example 3:

[0062] The difference from Embodiment 2 is that, as shown in Figures 1 and 7, the top of the placement ring 5 is provided with a fixation assembly for fixing the patient's limb. The fixation assembly includes a piston box 6 bolted to the top of the placement ring 5, a piston plate 15 vertically slidably fitted inside the piston box 6, a piston rod 16 fixedly bonded to the bottom of the piston plate 15, and a fixing plate 7 (in this embodiment, the fixing plate 7 is made of silicone material) fixedly bonded to the bottom of the piston rod 16, which passes through the top of the placement ring 5. The piston rod 16 is vertically slidably fitted with the placement ring 5. The piston box 6 contains a piston assembly for driving the piston plate 15 to slide vertically along the inner wall of the piston box 6. The piston assembly includes a third electrically controlled cylinder 14 bolted to the top wall of the piston box 6, and the output shaft of the third electrically controlled cylinder 14 is bolted to the top of the piston plate 15. A controller is used to control the operation of the third electrically controlled cylinder 14.

[0063] Specifically, as shown in Figures 1 and 7, after the patient aligns the examination point with the examination hole, the medical staff activates the third electric cylinder 14 through the controller. The output shaft of the third electric cylinder 14 pushes the piston plate 15 and the piston rod 16 to slide downward in the piston box 6. The piston rod 16 pushes the fixing plate 7 to move downward, thereby adaptively fixing the patient's limb, thus ensuring the stability of the examination and improving the accuracy of the examination results.

[0064] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
