Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a neurology diagnosis device. Background Art

[0002] Percussion hammer is a commonly used diagnostic instrument in neurology and plays a key role in the diagnosis process. Among them, the barbed roller percussion hammer has received some attention in clinical applications in recent years. The original intention of the design of this barbed roller percussion hammer is to stimulate muscles and meridians through the needle structure on the roller in the process of contacting and rolling with the patient's skin, so as to assist doctors in diagnosing the patient's nerve condition. In an ideal usage scenario, doctors can adjust the operating force based on experience and observation of patient reactions to obtain accurate diagnostic information. However, in actual use, due to the great differences in the perception and tolerance of pain among different patients, it is difficult for doctors to accurately judge the specific situation of each patient in advance during the diagnosis process. When a doctor uses a barbed roller percussion hammer, if the pressure applied is too great and the patient happens to have no obvious reaction to this stimulation, this may cause harm to the patient.

[0003] Chinese patent CN107714092B discloses a percussion hammer for neurology, in which the needle can be retracted along the extension direction of the first mounting hole to compress the first spring and deform in the extension direction of the second mounting hole, thereby forming a rotation restriction of the roller with the U-shaped fixing piece. Even if the doctor applies too much pressure, the roller can be stopped by the structure of the neurology percussion hammer itself, reducing the invisible harm to the patient. However, the patent has many delicate structures, which increases the difficulty of processing, and the method of limiting the rotation of the roller is used to prompt the doctor. If the doctor cannot react in time, the needle will still scratch the patient. Summary of the invention

DETAILED DESCRIPTION

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] An embodiment of a neurological diagnosis device of the present invention is as follows Figures 1 to 14 shown.

[0034] A neurological diagnosis device comprises a handle 100, a roller 200 and a plurality of diagnosis mechanisms 300. The roller 200 is rotatably mounted on the handle 100 around a horizontal axis, and the rotation axis direction of the roller 200 is a first direction.

[0035] A plurality of diagnostic mechanisms 300 are evenly distributed around a first direction in the roller 200, and the diagnostic mechanism 300 includes an adjustment rod 310, an adjustment sheet 320, and a needle 330. The adjustment rod 310, the adjustment sheet 320, and the needle 330 are sequentially arranged around the first direction in the roller 200, and sequentially arranged along a second direction in the roller 200, the second direction being the radial direction of the roller 200, and the needle 330 is located on a side of the adjustment rod 310 away from the horizontal axis of the roller 200 in the second direction.

[0036] The adjusting rod 310 is arranged in the roller 200 along the second direction and mounted on the roller 200, and the adjusting sheet 320 is an elastic sheet. The two ends of the adjusting sheet 320 along the second direction are respectively referred to as the first end and the second end, the first end of the adjusting sheet 320 is rotatably connected to the adjusting rod 310, the pricking needle 330 is arranged along the second direction, the second end of the adjusting sheet 320 is rotatably connected to one end of the pricking needle 330, and the other end of the pricking needle 330 can slide on the roller 200 along the second direction and extend out of the roller 200.

[0037] The line connecting the first end and the second end is called a first reference axis 350 , and the axis passing through the first end of the adjusting plate 320 and perpendicular to the axis of the needle 330 along the second direction is called a second reference axis 360 .

[0038] The neurology diagnosis device has a first state and a second state. In the first state, the first reference axis 350 is located on the side of the second reference axis 360 away from the horizontal axis of the roller 200 in the second direction, and the adjustment sheet 320 can cause the needle 330 to extend out of the roller 200 and limit the needle 330 to retract into the roller 200. In the second state, the first reference axis 350 is located on the side of the second reference axis 360 close to the horizontal axis of the roller 200 in the second direction, the needle 330 is retracted into the roller 200, and the adjustment sheet 320 limits the needle 330 from extending out of the roller 200. In the initial state, the neurology diagnosis device is in the first state.

[0039] Specifically, the end surface of the handle 100 away from the diagnosis mechanism 300 is rough, so as to increase the friction between the hand of medical personnel and the handle 100 when using it.

[0040] In this embodiment, a diagnostic mechanism 300 is provided. When in use, the medical staff holds the handle 100 to drive the roller 200 to rotate around the first direction. At this time, the neurological diagnostic device is in the first state, and the adjusting rod 310, the adjusting plate 320 and the needle 330 are arranged in sequence around the first direction in the roller 200. The force exerted by the adjusting plate 320 on the needle 330 can be equivalently replaced by the line connecting the first end and the second end of the adjusting plate 320, that is, the first reference axis 350, and the first reference axis 350 is inclined. Therefore, when the first reference axis 350 is located on the side of the second reference axis 360 away from the horizontal axis of the roller 200 in the second direction, the adjusting plate 320 applies a component force along the first reference axis 350 to the needle 330 along the second direction toward the side away from the horizontal axis of the roller 200, so that the adjusting plate 320 can cause the needle 330 to extend out of the roller 200. At this time, the roller 200 rolls to drive the needles 330 extending out of the roller 200 to roll to stimulate muscles and meridians, thereby diagnosing the patient's nerves.

[0041] When the force applied by the medical staff exceeds the force that the adjusting plate 320 can withstand, the needle 330 will gradually shrink into the roller 200. Since the two ends of the adjusting plate 320 are rotatably connected to the needle 330 and the adjusting rod 310 respectively, when the needle 330 shrinks, the adjusting plate 320 will be squeezed and deformed. If the force applied by the medical staff is too large, the first reference axis 350 is located on the side of the second reference axis 360 close to the horizontal axis of the roller 200 in the second direction. At this time, the adjusting plate 320 applies a component force along the first reference axis 350 to the needle 330 along the second direction close to the horizontal axis of the roller 200. Therefore, the needle 330 will no longer be able to extend out of the roller 200. At this time, the neurological diagnostic device is in the second state.

[0042] The adjustment sheet 320 is used to control the extension and retraction of the thorn needle 330. During normal use, the adjustment sheet 320 can cause the thorn needle 330 to extend out of the roller 200. If the force applied by the medical staff is too large, the thorn needle 330 will no longer actively pop out after being retracted into the roller 200. At this time, the roller 200 can continue to roll, but because the thorn needle 330 has been retracted, it can avoid causing harm to the patient and prevent the medical staff from applying too much force to scratch the patient. The diagnostic mechanism 300 has a simple structure and is easy to assemble, which is more suitable for processing and production. During transportation, the thorn needle 330 can be retracted into the roller 200, which is convenient for transporting the neurological diagnostic device.

[0043] In this embodiment, the adjusting piece 320 has a concave surface and a convex surface, and the concave surface is located on the side of the convex surface away from the horizontal axis of the roller 200 in the second direction. That is, the concave surface is arranged toward the horizontal axis of the roller 200, and the convex surface is arranged toward the inner wall of the roller 200. When the needle 330 shrinks in the roller 200, the adjusting piece 320 will deform, so that the first end and the second end of the adjusting piece 320 are close to each other. See the attached Figure 7 To Attachment Fig.10 shown.

[0044] In this embodiment, the roller 200 includes a rolling shell 210 and a rotating disk 220. Both the rolling shell 210 and the rotating disk 220 are circular. One end of the rolling shell 210 in the first direction is closed and the other end is through. The rotating disk 220 is mounted on the rolling shell 210 to block the rolling shell 210. A rotating block 230 is coaxially and fixedly connected to the rotating disk 220. The rotating block 230 is arranged along the first direction and is located on a side of the rotating disk 220 close to the rolling shell 210 in the first direction. The adjusting rod 310 is mounted on the rotating block 230. The rolling shell 210 and the rotating disk 220 are connected by a locking mechanism. The locking mechanism has a locking state and an unlocking state. When in the locking state, the locking mechanism restricts the rotating disk 220 from rotating in the first direction relative to the rolling shell 210. When in the unlocking state, the locking mechanism allows the rotating disk 220 to rotate in the first direction relative to the rolling shell 210.

[0045] Specifically, the rolling shell 210, the rotating disk 220, the rotating block 230 and the handle 100 are connected through the installation shaft 240, the installation shaft 240 is arranged along the first direction, and the rolling shell 210, the rotating disk 220, the rotating block 230 and the handle 100 are rotatably matched with the installation shaft 240. The locking mechanism includes a locking wheel 250 and a first elastic member 260. The locking wheel 250 is installed on the installation shaft 240 and is located on a side of the rotating disk 220 away from the rolling shell 210 in the first direction. The locking wheel 250 is threadedly matched with the installation shaft 240, and the first elastic member 260 is arranged between the rotating disk 220 and the locking wheel 250. The first elastic member 260 is arranged along the first direction and is a spring.

[0046] Further, a plurality of spherical protrusions 211 are arranged on the end surface of the rolling shell 210 along the first direction facing the rotating disk 220, and the plurality of spherical protrusions 211 are evenly distributed around the first direction on the rolling shell 210, and a plurality of ball grooves 221 and a plurality of arc grooves 222 evenly distributed around the first direction are opened on the end surface of the rotating disk 220 along the first direction facing the rolling shell 210, and the ball grooves 221 and the arc grooves 222 are alternately distributed in sequence around the first direction, and when the rolling shell 210 abuts against the rotating disk 220, the spherical protrusions 211 can be located in the ball grooves 221. When the locking mechanism is in a locked state, the spherical protrusions 211 are used to increase the interaction force between the rolling shell 210 and the rotating disk 220, so that the two can rotate synchronously.

[0047] Furthermore, the angle between the adjusting rod 310 and the corresponding needle 330 is α, α=25°, or the angle between the adjusting rod 310 and the corresponding needle 330 is β, β=30°.

[0048] By setting the locking mechanism, after the diagnostic mechanism 300 is installed, the rolling shell 210, the rotating disk 220, the rotating block 230 and the handle 100 are connected by the installation shaft 240, and then the rotating disk 220 can be manually rotated, and the adjusting rod 310 can be driven to rotate by the rotating block 230 to change the angle between the adjusting rod 310 and the correspondingly arranged needle 330, see the attached Figure 7 As shown, at this time, the angle between the adjusting rod 310 and the correspondingly arranged needle 330 is α, and α=25°.

[0049] Alternatively, see Appendix Fig.13 As shown, at this time, the angle between the adjustment rod 310 and the corresponding puncture needle 330 is β, β=30°. The increase in the angle between the adjustment rod 310 and the corresponding puncture needle 330 can make the puncture needle 330 easier to be pressed down, which can adapt to patients with different sensitivity levels and increase adaptability.

[0050] In this embodiment, the adjustment rod 310 is detachably connected to the rotating block 230. Specifically, the adjustment rod 310 includes an optical axis section and a threaded section, the optical axis section and the threaded section are fixedly connected, a plurality of thread grooves are provided on the rotating block 230, the plurality of thread grooves are evenly distributed in the circumferential direction of the rotating block 230, the plurality of thread grooves are arranged in a one-to-one correspondence with the plurality of adjustment rods 310, and the threaded sections of the adjustment rods 310 are rotatably matched with the threaded grooves arranged correspondingly thereto. During installation, the adjustment rod 310 is installed on the rotating block 230 by means of a threaded connection, which improves the convenience of installation. Alternatively, the adjustment rod 310 is clamped with the rotating block 230.

[0051] In this embodiment, the diagnostic mechanism 300 also includes a limit plate 340, which is arranged on the rotating block 230, and when the neurological diagnostic device is in the second state, the end surface of the limit plate 340 close to the adjusting plate 320 around the first direction can abut against the adjusting plate 320, and at this time, the angle between the end surface of the limit plate 340 close to the adjusting plate 320 around the first direction and the adjusting rod 310 is 5°.

[0052] Specifically, two adjusting rods 310 are provided, and the two adjusting rods 310 are sequentially arranged on the rotating block 230 along the first direction. In the first direction, the limiting piece 340 is located between the two adjusting rods 310 .

[0053] Furthermore, the limiting piece 340 is inclined around the end surface of the first direction close to the corresponding adjusting piece 320 .

[0054] After the angle adjustment between the adjusting rod 310 and the corresponding puncture needle 330 is completed, the locking wheel 250 is rotated. At this time, the transmission between the locking wheel 250 and the mounting shaft 240 takes effect. The locking wheel 250 will move on the mounting shaft 240 while rotating, and the first elastic member 260 is used to prompt the rotating disk 220 to move on the mounting shaft 240, so that the rolling shell 210 abuts against the rotating disk 220. At this time, the locking mechanism is in a locked state, and the locking mechanism limits the rotating disk 220 from rotating relative to the rolling shell 210 in a first direction, and then the patient can be diagnosed.

[0055] When the force applied by the medical staff is too large, the needle 330 is retracted into the roller 200, that is, at this time, the first reference axis 350 is located on the side of the second reference axis 360 close to the horizontal axis of the roller 200 in the second direction, and the neurological diagnosis device is in the second state. If the patient needs to be diagnosed again, the locking mechanism needs to be unlocked. The specific operation is to rotate the locking wheel 250 in the reverse direction, so that the rolling shell 210 is no longer in contact with the rotating disk 220. At this time, the rotating disk 220 can rotate relative to the rolling shell 210 around the first direction, and then manually rotate the rotating disk 220 to make the rolling shell 210 and the rotating disk 220 relative to each other. The stopper 340 on the rotating block 230 causes the adjusting piece 320 abutting against it to rotate. In this process, the angle between the end surface of the stopper 340 close to the adjusting piece 320 around the first direction and the adjusting rod 310 is always maintained at 5° until the first reference axis 350 is located again on the side of the second reference axis 360 away from the horizontal axis of the roller 200 in the second direction. At this time, the adjusting piece 320 will cause the needle 330 to extend out of the roller 200 to achieve reset. When resetting, the rolling shell 210 can be manually tapped to reduce the resistance of the needle 330 when it is extended, so as to assist the needle 330 in resetting. Before the next use, the angle between the adjusting rod 310 and the needle 330 can be readjusted.

[0056] In this embodiment, a pointer 212 is provided on the outer wall of the rolling shell 210, and a scale value 223 is provided on the outer wall of the rotating disk 220. By observing the scale value 223 corresponding to the position indicated by the pointer 212, the angle between the adjustment rod 310 and the correspondingly arranged needle 330 can be adjusted.

[0057] In combination with the above embodiments, the specific working process is as follows:

[0058] After the diagnostic mechanism 300 is installed, the rolling shell 210, the rotating disk 220, the rotating block 230 and the handle 100 are connected by the installation shaft 240, and then the rotating disk 220 can be manually rotated, and the adjusting rod 310 is driven to rotate by the rotating block 230, so as to change the angle between the adjusting rod 310 and the corresponding puncture needle 330, so as to adapt to patients with different sensitivity levels and increase adaptability. After the angle between the adjusting rod 310 and the corresponding puncture needle 330 is adjusted, the locking wheel 250 is rotated, and the transmission between the locking wheel 250 and the installation shaft 240 takes effect. The locking wheel 250 will move on the installation shaft 240 while rotating, and the first elastic member 260 will cause the rotating disk 220 to move on the installation shaft 240, so that the rolling shell 210 abuts against the rotating disk 220. At this time, the locking mechanism is in a locked state, and the locking mechanism restricts the rotating disk 220 from rotating around the first direction relative to the rolling shell 210, and then the patient can be diagnosed.

[0059] When in use, the medical staff holds the handle 100 to drive the roller 200 to rotate in the first direction. At this time, the neurological diagnosis device is in the first state, and the adjustment sheet 320 applies a component force along the first reference axis 350 to the needle 330 along the second direction toward the side away from the horizontal axis of the roller 200, so that the adjustment sheet 320 can cause the needle 330 to extend out of the roller 200. At this time, the rolling of the roller 200 drives the needle 330 extending out of the roller 200 to roll to stimulate the muscles and meridians, thereby diagnosing the patient's nerves.

[0060] When the force applied by the medical staff exceeds the force that the regulating plate 320 can withstand, the needle 330 will gradually shrink into the roller 200. Since the two ends of the regulating plate 320 are rotatably connected to the needle 330 and the regulating rod 310 respectively, when the needle 330 shrinks, the regulating plate 320 will be squeezed and deformed. If the force applied by the medical staff is too large, the first reference axis 350 is located on the side of the second reference axis 360 close to the horizontal axis of the roller 200 in the second direction. At this time, the regulating plate 320 applies a component force along the first reference axis 350 to the needle 330 along the second direction close to the horizontal axis of the roller 200. Therefore, the needle 330 will no longer be able to extend out of the roller 200. At this time, the neurological diagnostic device is in the second state, and the angle between the end face of the limiting plate 340 close to the regulating plate 320 in the first direction and the regulating rod 310 is 5°. After being retracted into the roller 200, the lancet 330 will no longer actively pop out, and the roller 200 can continue to roll. However, since the lancet 330 has been retracted, it can avoid causing harm to the patient and prevent the medical staff from applying excessive force to scratch the patient.

[0061] If the patient needs to be diagnosed again, the locking mechanism needs to be unlocked. The specific operation is to rotate the locking wheel 250 in the opposite direction, so that the rolling shell 210 is no longer in contact with the rotating disk 220. At this time, the rotating disk 220 can rotate relative to the rolling shell 210 about the first direction, and then the rotating disk 220 is manually rotated to make the rolling shell 210 and the rotating disk 220 rotate relative to each other, so that the limiting piece 340 on the rotating block 230 prompts the adjusting piece 320 abutting therewith to rotate. In this process, the angle between the end face of the limiting piece 340 close to the adjusting piece 320 about the first direction and the adjusting rod 310 is always maintained at 5°, until the first reference axis 350 is again located on the side of the second reference axis 360 away from the horizontal axis of the roller 200 in the second direction. At this time, the adjusting piece 320 will prompt the needle 330 to extend out of the roller 200 to achieve resetting, and when resetting, the rolling shell 210 can be manually tapped to reduce the resistance of the needle 330 when it is extended, thereby assisting the resetting of the needle 330. Before the next use, the angle between the adjusting rod 310 and the puncture needle 330 can be readjusted.
