Description

Technical Field

[0001] The present invention relates to the field of percussion hammers, and more specifically to a percussion hammer for neurological examinations. Background Art

[0002] Neurology mainly studies the etiology, pathogenesis, clinical manifestations, diagnosis, treatment, and prevention of nervous system diseases. The nervous system consists of the central nervous system (brain and spinal cord) and the peripheral nervous system (cranial nerves, spinal nerves, and autonomic nerves). Neurological diseases cover various disorders that affect the structure and function of the nervous system.

[0003] During the examination by doctors, patients in neurology departments often lie in bed. Doctors will continuously tap different positions of the patients with a percussion hammer to make a diagnosis based on the nerve responses. However, current percussion hammers for neurological examinations all require doctors to hold them by hand for continuous tapping examinations. This will increase the labor intensity of doctors. At the same time, doctors need to constantly move around to tap different positions of the patients. Moreover, due to manual control of the tapping force, the forces are different, resulting in different tapping test results and causing inaccuracies in the tests. Summary of the Invention

A support column is fixedly connected to the side of the second gear away from the first gear. A support plate is fixedly connected to the upper end of the support column. A plurality of installation rods arranged in an array are fixedly connected to the upper end of the support plate.

[0006] Specifically, a connecting cylinder is fixedly connected to the upper end of the mounting rod. Moving holes are respectively formed through the centers of both sides of the connecting cylinder. Sliding ports are respectively formed through both sides of the connecting cylinder. A pull rod is slidably connected to the moving holes. A connecting plate is fixedly sleeved on one side of the pull rod close to the sliding port.

The output end of the driving motor 4 is fixedly connected with a first screw rod 5, and the top end rod wall of the first screw rod 5 is rotationally connected to the inner wall of the top end of the installation box 1 through a bearing. A screw sleeve 6 is threadedly connected to the rod wall of the first screw rod 5. On both sides of the screw sleeve 6, sliding plates 7 are fixedly connected. The side of the sliding plate 7 away from the screw sleeve 6 is slidably connected inside the first sliding groove 2. At the upper ends of the sliding plates 7, support rods 8 are fixedly connected. The top ends of the support rods 8 pass through the through holes 3 and extend to the outside of the installation box 1. The top ends of the support rods 8 are jointly fixedly connected with a connection box 9. A tooth slot 10 is provided through the top end of the connection box 9. On one inner wall of the connection box 9, a stepping motor 11 is fixedly connected. The output end of the stepping motor 11 is fixedly connected with a first gear 12 through a locking device. On both sides of the tooth slot 10, a rotating rod 13 is rotationally connected through a bearing. A second gear 14 is fixedly connected to the rod wall of the rotating rod 13. The second gear 14 is meshed and connected to the first gear 12. The side of the second gear 14 away from the first gear 12 passes through the tooth slot 10 and extends to the outside of the connection box 9. A support column 15 is fixedly connected to the side of the second gear 14 away from the first gear 12. A support plate 16 is fixedly connected to the upper end of the support column 15. A plurality of installation rods 17 arranged in an array are fixedly connected to the upper end of the support plate 16; At the upper ends of the installation rods 17, connection cylinders 18 are fixedly connected. At the central parts of both sides of the connection cylinder 18, moving holes 19 are respectively provided. On both sides of the connection cylinder 18, sliding openings 20 are respectively provided. A pull rod 21 is jointly slidably connected to the moving holes 19. On the side of the pull rod 21 close to the sliding opening 20, a connecting plate 22 is fixedly sleeved. The two sides of the connecting plate 22 pass through the sliding openings 20 and extend to the outside of the connection cylinder 18. A spring 23 is fixedly connected between the connecting plate 22 and the connection cylinder 18. The side of the pull rod 21 away from the connecting plate 22 is fixedly connected with an impact plate 24.

[0019] Specifically, a U-shaped frame 27 is fixedly connected to the lower end of the installation box 1. A threaded hole 28 is provided through one side of the U-shaped frame 27. A second screw rod 29 is threadedly connected to the threaded hole 28. The second screw rod 29 located inside the U-shaped frame 27 is rotationally connected with a clamping plate 30 through a bearing. A second sliding groove 31 is provided inside the U-shaped frame 27. A sliding plate 32 is fixedly connected to the upper end of the clamping plate 30. The upper end of the sliding plate 32 is slidably connected inside the second sliding groove 31.

[0020] Specifically, a soft pad is fixedly connected to the side of the impact plate 24 away from the connecting cylinder 18, a pulling plate 26 is fixedly connected to the side of the pull rod 21 away from the impact plate 24, and a plurality of scales 25 are provided on the outer wall of the connecting cylinder 18 on both sides of the sliding opening 20. This is beneficial to increasing the comfort of the patient when the impact plate 24 impacts through the soft pad. At the same time, it is convenient for the doctor to pull and detect through the pulling plate 26. Moreover, the scales 25 facilitate the doctor to increase the accuracy of the percussion force during detection, making it convenient for detection.

[0021] Specifically, a turntable 33 is fixedly connected to the side of the second screw rod 29 away from the clamping plate 30, which is beneficial to driving the second screw rod 29 to rotate conveniently through the turntable 33, so as to quickly clamp the U-shaped frame 27 and the clamping plate 30 on the hospital bed.

[0022] During use, when a doctor needs to use a percussion instrument to perform nerve detection on a patient on a hospital bed, insert the U-shaped frame 27 on the railing of the hospital bed, and then rotate the turntable 33. The turntable 33 drives the second screw rod 29 under force. The second screw rod 29 rotates in cooperation with the threaded hole 28. At this time, under the sliding limit action of the second sliding groove 31 and the sliding plate 32 and the continuous pushing of the bearing, the clamping plate 30 moves until the clamping plate 30 and the other side of the U-shaped frame 27 are stably clamped to the railing. At this time, as needed, start the driving motor 4. The output end of the driving motor 4 drives the first screw rod 5 to rotate stably through the bearing. When the first screw rod 5 rotates, it drives the screw sleeve 6. When the screw sleeve 6 is under force, it continuously moves under the sliding limit action of the first sliding groove 2 and the sliding plate 7. When the screw sleeve 6 moves, it drives the support rod 8 to brake through the sliding plate 7. As the support rod 8 continuously moves through the through hole 3, it drives the support plate 16 and the percussion instrument to move to a suitable position. Then start the stepping motor 11. The output end of the stepping motor 11 drives the first gear 12 to rotate. When the first gear 12 rotates, it meshes with and drives the second gear 14. As the second gear 14 rotates in the tooth slot 10, the second gear 14 will drive the support plate 16 to adjust to a suitable angle through the support column 15. The locking device on the stepping motor 11 will perform the limit. Then the doctor pulls the pulling plate 26. The pulling plate 26 drives the pull rod 21 under force. The pull rod 21 pulls the connecting plate 22 through the moving hole 19. The connecting plate 22 moves inside the sliding opening 20 and stretches the spring 23 at the same time. When the spring 23 stretches, it drives the impact plate 24 to move. At this time, the doctor controls the force through the scale 25 on the connecting cylinder 18, and then releases the pulling plate 26 multiple times to drive the impact plate 24 to strike the patient, increasing the accuracy of detecting the patient's nerves.
