Description

Technical Field

[0001] This invention belongs to the field of auxiliary medical examination technology, specifically referring to an auxiliary positioning device for electromyography examination. Background Technology

[0002] In electromyography (EMG) examinations, accurate location of the testing points is crucial for ensuring accurate results. Currently, clinical practice mainly relies on physicians manually determining the testing points based on anatomical knowledge and experience. This method has the following problems: The accuracy of positioning is greatly affected by subjective factors: different doctors have different experience and operating habits, and may make different judgments on the same point for the same patient and the same examination site. Especially for novice doctors, it is easy to cause positioning deviation due to unfamiliarity with anatomical structures, which affects the reliability of examination results.

[0003] Low operational efficiency: Electromyography examinations usually require testing multiple symmetrically distributed points. Traditional manual positioning requires marking each point individually, which is cumbersome and time-consuming, increasing the patient's examination time and discomfort.

[0004] Poor consistency in symmetrical point location: Most muscle groups in the human body are symmetrically distributed, and the corresponding detection points also need to be set symmetrically. However, manual positioning makes it difficult to guarantee the absolute symmetry of the points on both sides, which may lead to errors in the comparison of data from both sides and affect the accuracy of diagnosis.

[0005] Lack of objective auxiliary guidance: Existing positioning methods rely heavily on doctors' visual judgment and touch, lacking intuitive quantitative indicators and auxiliary positioning tools. When patients have special body shapes or anatomical variations, positioning difficulties are more likely to occur.

[0006] Therefore, there is an urgent need for an electromyography (EMG) examination auxiliary device that can achieve automated and precise positioning and efficiently match symmetrical points, in order to solve the problems of insufficient accuracy and low efficiency of existing manual positioning methods and improve the standardization and reliability of EMG examination. Summary of the Invention

[0007] To address the above issues and overcome the shortcomings of existing technologies, this invention provides an auxiliary positioning device for electromyography (EMG) examination. Through the switching of the gear shifting component, a single drive motor can control the lateral and longitudinal movements of the projection lamp, allowing for flexible adjustment of its position. Furthermore, a shift fork controls the sliding of the sliding clutch plate. The sliding clutch plate, through its engagement with the worm gear and the drive gear, controls the transmission path of the driving force, thus achieving the technical effect of one drive source controlling two actuators.

[0008] The technical solution adopted by the present invention is as follows: The present invention proposes an auxiliary positioning device for electromyography examination, including a spinal alignment mechanism, a dual-mode drive mechanism and a lateral adjustment mechanism. The dual-mode drive mechanism is arrayed on the spinal alignment mechanism, and the lateral adjustment mechanism is arranged on the dual-mode drive mechanism. The spinal alignment mechanism includes a support assembly and a longitudinal beam assembly, the longitudinal beam assembly being disposed on the support assembly, and the dual-mode drive mechanism array being disposed on the longitudinal beam assembly; The dual-mode drive mechanism includes a slide plate, a longitudinal drive assembly, and a shift assembly. The longitudinal drive assembly is located below the slide plate, and the shift assembly is located below the slide plate.

[0009] By switching gears, a single drive motor can control the horizontal and vertical movements of the projection lamp, allowing for flexible adjustment of its position.

[0010] Furthermore, the longitudinal drive assembly includes a drive motor, a worm gear, a driving gear, and a driven gear. The drive motor is mounted on a slide plate, and a polygonal slide bar is provided on the output shaft of the drive motor. The worm gear and the driving gear are rotatably mounted on the output shaft of the drive motor, and the driven gear is mounted on the longitudinal beam assembly.

[0011] Preferably, the shift assembly includes a sliding clutch plate, a shift fork, and a sliding seat. The sliding clutch plate is engaged and slidably disposed on the polygonal slide rod portion. The sliding clutch plate rotates with the polygonal slide rod portion. The sliding clutch plate is rotatably disposed in the shift fork. The shift fork is engaged and slidably disposed in the sliding seat. The two ends of the sliding seat are symmetrically provided with electromagnets capable of attracting the shift fork.

[0012] The sliding of the sliding clutch plate can be controlled by the shift fork. The sliding clutch plate, through its engagement with the worm gear and the drive gear, can control the transmission path of the driving force, thereby achieving the technical effect of one drive source controlling two actuators.

[0013] Furthermore, the support assembly includes a hospital bed, a frame support, and an adjustable slider. The frame support is located above the hospital bed, and the adjustable slider is slidably mounted on the frame support. The frame support is also equipped with a camera capable of sensing the human body contour and position.

[0014] The camera can sense the patient's body contours, and the software can calculate the location of the examination points. After adjusting the projector to that position, the projector can project light onto the human body surface to assist the doctor in positioning the examination points.

[0015] Preferably, the longitudinal beam assembly includes a guide rod, a fixed lead screw, and a nut. The guide rod and the fixed lead screw are fixedly connected between two adjusting sliders. The nut is rotatably disposed in the sliding plate. The nut and the fixed lead screw are connected by a threaded transmission. The driven gear is fixedly connected to the nut.

[0016] The longitudinal beam assembly coincides with the patient's spine in the projection direction. Therefore, the lateral adjustment mechanisms symmetrically set on both sides of the slide can correspond to symmetrical positions on the human body and meet the indication of most target points.

[0017] Furthermore, the lateral adjustment mechanism includes a lateral guide component and a lateral drive component. The lateral guide component is symmetrically arranged on both sides of the slide plate, and the lateral drive component is arranged on the slide plate.

[0018] Preferably, the lateral guide assembly includes a guide rod, a sliding block, and a projection light. The guide rod is fixed to both sides of the slide plate, the sliding block is engaged and slidably mounted on the guide rod, and the projection light is located at the bottom of the sliding block.

[0019] As a further preferred embodiment of the present invention, the transverse drive assembly includes a lead screw seat, a bidirectional lead screw, and a worm gear. The lead screw seat is disposed on a slide plate, the bidirectional lead screw is rotatably disposed in the lead screw seat, and the worm gear is fixedly connected to the middle position of the bidirectional lead screw. The worm gear and the worm cooperate with each other.

[0020] The sliding block moves symmetrically under the threaded drive of the bidirectional lead screw, and the end of the bidirectional lead screw is rotatably located in the lead screw seat.

[0021] Since most of the detection points are symmetrically distributed, after the longitudinal beam assembly coincides with the spine, the symmetrical movement of the sliding block and the projection lamp can be controlled by the bidirectional lead screw, thereby achieving rapid positioning. For a few asymmetrical point indications, it is only necessary to set the projection lamp on one side.

[0022] The beneficial effects achieved by the present invention using the above structure are as follows: (1) By switching the gear shifting component, the horizontal and vertical movements of the projection lamp can be controlled by a drive motor, and its position can be flexibly adjusted.

[0023] (2) The sliding of the sliding clutch plate can be controlled by the shift fork. The sliding clutch plate can control the transmission path of the driving force by engaging with the worm and the drive gear respectively, thereby achieving the technical effect of one drive source controlling two actuators.

[0024] (3) The camera can perceive the patient’s body outline and then use software to calculate the location of the examination point. After adjusting the projector to the position, the projector can project light onto the human body surface to assist the doctor in positioning.

[0025] (4) The longitudinal beam assembly coincides with the patient's spine in the projection direction. Therefore, the lateral adjustment mechanism symmetrically set on both sides of the slide can correspond to the symmetrical position on the human body and meet the indication of most target points.

[0026] (5) Since most of the detection points are symmetrically distributed, after the longitudinal beam assembly coincides with the spine, the symmetrical movement of the sliding block and the projection lamp can be controlled by the bidirectional screw, thereby achieving rapid positioning. For a few asymmetrical point indications, it is only necessary to set the projection lamp on one side. Attached Figure Description

Therefore, they should not be construed as limitations on this invention.

[0032] like Figures 1-8 As shown, the present invention proposes an auxiliary positioning device for electromyography examination, including a spinal alignment mechanism 1, a dual-mode drive mechanism 2 and a lateral adjustment mechanism 3. The dual-mode drive mechanism 2 is arrayed on the spinal alignment mechanism 1, and the lateral adjustment mechanism 3 is disposed on the dual-mode drive mechanism 2. The spinal alignment mechanism 1 includes a support assembly 4 and a longitudinal beam assembly 5. The longitudinal beam assembly 5 is mounted on the support assembly 4, and the dual-mode drive mechanism 2 is arrayed on the longitudinal beam assembly 5. The dual-mode drive mechanism 2 includes a slide plate 12, a longitudinal drive assembly 13, and a shift assembly 14. The longitudinal drive assembly 13 is located below the slide plate 12, and the shift assembly 14 is located below the slide plate 12.

[0033] By switching the gear shifting component 14, the horizontal and vertical movements of the projection lamp 28 can be controlled by a drive motor 15, allowing for flexible adjustment of its position.

[0034] The longitudinal drive assembly 13 includes a drive motor 15, a worm gear 16, a drive gear 17, and a driven gear 18. The drive motor 15 is mounted on the slide plate 12. A polygonal slide bar portion 22 is provided on the output shaft of the drive motor 15. The worm gear 16 and the drive gear 17 are rotatably mounted on the output shaft of the drive motor 15. The driven gear 18 is mounted on the longitudinal beam assembly 5.

[0035] The shift assembly 14 includes a sliding clutch plate 19, a shift fork 20, and a sliding seat 21. The sliding clutch plate 19 is engaged and slidably disposed on the polygonal slide rod 22. The sliding clutch plate 19 rotates with the polygonal slide rod 22. The sliding clutch plate 19 is rotatably disposed in the shift fork 20. The shift fork 20 is engaged and slidably disposed in the sliding seat 21. Electromagnets 23 capable of attracting the shift fork 20 are symmetrically disposed at both ends of the sliding seat 21.

[0036] The sliding of the sliding clutch plate 19 can be controlled by the shift fork 20. The sliding clutch plate 19, through its engagement with the worm gear 16 and the drive gear 17 respectively, can control the transmission path of the driving force, thereby achieving the technical effect of one drive source controlling two actuators.

[0037] The support assembly 4 includes a hospital bed 6, a frame support 7, and an adjustable slider 8. The frame support 7 is located above the hospital bed 6, and the adjustable slider 8 is slidably mounted on the frame support 7. The frame support 7 is also equipped with a camera that can sense the outline and position of the human body.

[0038] The camera can perceive the patient's body contours, and the software can calculate the location of the examination points. After adjusting the projector 28 to the position, the projector 28 can project light onto the human body surface to assist the doctor in positioning operations.

[0039] The longitudinal beam assembly 5 includes a guide rod 9, a fixed lead screw 10, and a nut 11. The guide rod 9 and the fixed lead screw 10 are fixedly connected between two adjusting sliders 8. The nut 11 is rotatably disposed in the slide plate 12. The nut 11 and the fixed lead screw 10 are connected by a threaded transmission. The driven gear 18 is fixedly connected to the nut 11.

[0040] The longitudinal beam assembly 5 coincides with the patient's spine in the projection direction. Therefore, the lateral adjustment mechanism 3, which is symmetrically arranged on both sides of the slide plate 12, can correspond to the symmetrical position on the human body and meet the indication of most target points.

[0041] The lateral adjustment mechanism 3 includes a lateral guide component 24 and a lateral drive component 25. The lateral guide component 24 is symmetrically arranged on both sides of the slide plate 12, and the lateral drive component 25 is arranged on the slide plate 12.

[0042] The lateral guide assembly 24 includes a guide rod 26, a sliding block 27, and a projection lamp 28. The guide rod 26 is fixed to both sides of the slide plate 12, the sliding block 27 is engaged and slidably disposed on the guide rod 26, and the projection lamp 28 is located at the bottom of the sliding block 27.

[0043] The transverse drive assembly 25 includes a lead screw seat 29, a bidirectional lead screw 30, and a worm gear 31. The lead screw seat 29 is mounted on the slide plate 12, the bidirectional lead screw 30 is rotatably mounted in the lead screw seat 29, and the worm gear 31 is fixed to the middle position of the bidirectional lead screw 30. The worm gear 31 and the worm 16 cooperate with each other.

[0044] The sliding block 27 moves symmetrically under the threaded transmission of the bidirectional lead screw 30, and the end of the bidirectional lead screw 30 is rotatably located in the lead screw seat 29.

[0045] Since most of the detection points are symmetrically distributed, after the longitudinal beam assembly 5 coincides with the spine, the symmetrical movement of the sliding block 27 and the projection lamp 28 can be controlled by the bidirectional lead screw 30, thereby achieving rapid positioning. For a few asymmetrical point indications, it is only necessary to set the projection lamp 28 on one side.

[0046] In actual use, the patient first needs to lie flat in the approximate middle position of the hospital bed 6, and then remain in a still lying position.

[0047] The camera on the frame bracket 7 can sense the outline of the human body, including its size and the location of each part; then, by corresponding with the background data, it calculates the specific location of the detection point and converts it into two-dimensional coordinates on the plane where the frame bracket 7 is located.

[0048] Then, based on the coordinates above, adjust the position of each projection lamp 28. The specific adjustment steps are as follows: First, adjust the slider 8 according to the position of the human spine so that the fixed screw 10 coincides with the patient's spine in the projection direction.

[0049] Then, the electromagnet 23 on one side is energized. Under the magnetic attraction of the electromagnet 23, the fork 20 pushes the sliding clutch plate 19 to slide along the polygonal slide bar 22 until the sliding clutch plate 19 and the drive gear 17 abut and engage. At this time, the drive motor 15 can rotate the driven gear 18 through the drive gear 17, thereby realizing the longitudinal sliding adjustment of the slide plate 12. Multiple sets of skateboards 12 can be adjusted in position simultaneously.

[0050] After the slide plate 12 is adjusted, the electromagnet 23 on the other side is energized. Under the magnetic attraction of the electromagnet 23, the fork 20 pushes the sliding clutch plate 19 to slide along the polygonal slide rod 22 until the sliding clutch plate 19 and the worm 16 abut and engage. At this time, the drive motor 15 can drive the worm wheel 31 and the double-acting screw 30 to rotate through the worm 16, thereby realizing the lateral sliding adjustment of the sliding block 27. Finally, turn on the projector lamp 28. The projector lamp 28 will project light onto the surface of the human body to mark the points for electromyography examination and assist the doctor in applying the patches.

[0051] Since most of the detection points are symmetrically distributed relative to the spine, after the fixed screw 10 coincides with the spine, the symmetrical movement of the sliding block 27 and the projection lamp 28 can be controlled by the bidirectional screw 30, thereby achieving rapid positioning. For a few asymmetrical point indications, it is only necessary to set the projection lamp 28 on one side.
