Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a neurologic department limb sensation adjustable percussion device. Background Technique

[0002] Neurology is a secondary discipline related to nerves, mainly diagnosing and treating cerebrovascular diseases, migraine, cerebral inflammatory diseases, encephalitis, meningitis, myelitis, epilepsy, dementia, metabolic diseases and genetic diseases, trigeminal neuralgia, sciatica, peripheral neuropathy, myasthenia gravis, etc. Local nerve damage, peripheral nerve numbness, and myasthenia gravis are common diseases in neurology. When examining the local nerves of a patient's limbs, certain external stimuli need to be given to the examination site, and the medical staff can judge the patient's disease condition based on the patient's conditioned reflex response.

[0003] Chinese Patent Document CN213910299U discloses a neurologic department limb sensation percussion device, including a sleeve and a grip. A partition is fixedly connected to the inner side wall of the sleeve, a first compression spring is fixedly connected to the side of the partition, and a first percussion column is fixedly connected to the end of the first compression spring away from the partition. In this neurologic department limb sensation percussion device, through the settings of the first compression spring, the first percussion column, the second percussion column, the tension spring, the clamping plate, and the clamping groove, medical staff can use the first percussion column to percuss the limb nerves of the patient. The first compression spring can ensure the force during percussion and prevent excessive percussion. The second percussion column can accurately percuss the nerves of small parts. When the clamping plate is clamped at different positions in the clamping groove, when the clamping plate is not clamped with the clamping groove, the second percussion column will pop out outward under the action of the tension spring, and different intensities of stimuli can be applied to the patient's nerves, which is more convenient for the progress of the examination work.

[0023] In order to make the technical means, creative features, achieved purposes and functions of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0024] AsFigure 1 , Figure 2 As shown in Figure 2 , a neurologic limb sensation adjustable percussion device includes a hammer body 1. A partition 2 is fixedly sleeved at a position near the left side inside the hammer body 1. A first percussion column 3 is movably sleeved at a position near the left side inside the hammer body 1. A first spring 4 is movably sleeved at a position near the left side inside the hammer body 1, and the first spring 4 is located between the partition 2 and the first percussion column 3. An adjusting mechanism 5 is movably sleeved at a position near the right side inside the hammer body 1. A rotating mechanism 6 is fixedly connected to the middle left side of the lower side of the hammer body 1. A hammer handle 7 is fixedly connected to the lower side of the rotating mechanism 6.

[0025] It should be noted that a rubber sleeve is fixedly sleeved at a position near the lower side of the outer side of the hammer handle 7 to play an anti-slip role. Medical staff can use the first percussion column 3 to percuss the limb nerves of patients. The first spring 4 can ensure the force during percussion and prevent excessive percussion.

[0026] As Figures 2 - 4 shown in Figures 2 - 4 , the adjusting mechanism 5 includes a moving plate 51. The outer side of the moving plate 51 is movably sleeved at a position near the right side inside the hammer body 1. A rotating plate 52 is rotatably connected to the inner side of the moving plate 51. Four second springs 53 are movably sleeved in the mechanism holes on the outer side of the rotating plate 52. Four claw teeth 54 are movably sleeved in the mechanism holes on the outer side of the rotating plate 52, and the claw teeth 54 are located on the side close to the hammer body 1 of the second springs 53. Four annularly distributed card racks 55 are fixedly connected to the inner side of the hammer body 1. The side of the claw teeth 54 away from the second springs 53 is meshed and connected with the side of the card racks 55 away from the hammer body 1. The front and rear sides of the moving plate 51 are fixedly connected with a push frame 56 through a first cylinder, and the inner side of the push frame 56 is movably sleeved on the outer side of the hammer body 1.

[0027] It should be noted that when the push frame 56 is pushed, the push frame 56 drives the moving plate 51 to move leftward. The tooth shapes of the claw teeth 54 and the card racks 55 are both right-angled triangles, and the vertical surfaces face the right side, so that the card racks 55 fix the claw teeth 54, making the moving plate 51 only move in one direction.

[0028] As Figure 2 , Figure 3 shown in Figure 2 and Figure 3 , a third spring 57 is movably sleeved inside the hammer body 1, and the third spring 57 is located between the moving plate 51 and the partition 2. The upper rear side of the rotating plate 52 is fixedly connected with a push button 58 through a second cylinder. The right-side axis center of the moving plate 51 is fixedly connected with a second percussion column 59.

[0029] It should be noted that when the push button 58 is pushed, the push button 58 drives the rotating plate 52 to rotate, so that the claw teeth 54 are disengaged from the inner side of the card racks 55, and the third spring 57 pushes the moving plate 51 to make the second percussion column 59 pop out to precisely percuss the nerves of small parts of patients.

[0030] As shown Figure 2 in the figure, a protective arc plate 510 is rotatably connected to the outer side of the hammer body 1, and the second cylinder is slidably connected to a chute formed in the upper side of the protective arc plate 510.

[0031] It should be noted that the protective arc plate 510 is used to protect the outer side of the hammer body 1 to reduce the size of the opening on the upper side of the hammer body 1.

[0032] As shown Figure 4 in the figure, a rubber pad 511 is fixedly connected to the right side surface of the inner side of the hammer body 1.

[0033] It should be noted that the rubber pad 511 is used to buffer the moving plate 51 and reduce the impact of the moving plate 51 on the right side surface of the inner side of the hammer body 1.

[0034] As shown Figure 1 and Figure 5 in the figure, the rotating mechanism 6 includes a rotating seat 61. The upper side of the rotating seat 61 is fixedly connected to the position on the lower side of the hammer body 1 that is slightly to the left of the middle. Two fourth springs 62 symmetrically distributed in the front and back are movably sleeved inside the rotating seat 61. Two clamping rods 63 symmetrically distributed in the front and back are movably sleeved inside the rotating seat 61, and the clamping rods 63 are located on the sides of the fourth springs 62 that are far away from each other. The outer wall shape of the clamping rods 63 is square. Fixing plates 64 are movably sleeved on the outer sides of the two clamping rods 63 at positions far away from the fourth springs 62. The lower side of the fixing plates 64 is fixedly connected to the upper side of the hammer handle 7. Protective shells 65 are fixedly connected to the sides of the two fixing plates 64 that are far away from the rotating seat 61. Press plates 66 are movably sleeved inside the two protective shells 65, and the convex blocks on the side of the press plates 66 close to the rotating seat 61 are in mutual contact with the surfaces of the clamping rods 63 that are far away from the fourth springs 62.

[0035] It should be noted that when the clamping rods 63 are movably sleeved inside the fixing plates 64, the hammer handle 7 and the hammer body 1 cannot rotate relative to each other. Press the press plate 66, causing the press plate 66 to push the clamping rods 63, so that the clamping rods 63 are disengaged from the inside of the fixing plates 64, allowing the hammer handle 7 and the hammer body 1 to rotate relative to each other.

[0036] Working principle of the utility model: First, push the push frame 56, causing the push frame 56 to drive the moving plate 51 to move leftward. The tooth shapes of the claw 54 and the rack teeth 55 on the rack are both right-angled triangles, and the vertical surfaces face rightward, causing the rack 55 to fix the claw 54, so that the moving plate 51 can only move unidirectionally. Push the push button 58, causing the push button 58 to drive the rotating plate 52 to rotate, so that the claw 54 disengages from the inner side of the rack 55, causing the third spring 57 to push the moving plate 51 to eject the second knocking column 59, and precisely knock the nerves in small parts of the patient. Through the engagement of the claw 54 and the rack 55, the whole moving plate 51 is fixed. Since the third spring 57 applies force to the middle of the left side of the rotating plate 52, the forces on all parts of the moving plate 51 are balanced, and the second cylinder does not play a role in fixing the moving plate 51, reducing the pressure on one side of the whole and prolonging the service life of the components. Finally, when the clamping rod 63 is movably sleeved inside the fixing plate 64, the hammer handle 7 and the hammer body 1 cannot rotate relative to each other. Press the pressing plate 66, causing the pressing plate 66 to push the clamping rod 63, so that the clamping rod 63 disengages from the inner side of the fixing plate 64, causing the hammer handle 7 and the hammer body 1 to rotate relative to each other. By movably sleeving the pressing plate 66 on one side of the fixing plate 64, the purpose of fixing the hammer handle 7 and the hammer body 1 is achieved. Press the pressing plate 66, causing the hammer body 1 to rotate relative to the hammer handle 7, so that the directions of the hammer handle 7 and the hammer body 1 are the same, facilitating the overall storage.
