Description

Technical Field

[0001] The present invention relates to the technical field of percussion examination, and particularly relates to a percussion examination device for clinical neurology. Background Art

[0002] Neurology is a secondary discipline regarding nerves and does not fall within the concept of internal medicine. It mainly admits patients with cerebrovascular diseases, migraines, cerebral inflammatory diseases, myelitis, epilepsy, dementia, metabolic diseases and genetic predisposition diseases, trigeminal neuralgia, sciatica, peripheral neuropathy, myasthenia gravis, etc. During clinical examinations, doctors will use a percussion hammer to strike the patient's body surface to evaluate the function of the nervous system.

[0003] Conventional percussion hammers are composed of a handle and a hammer head. They have a simple structure but cannot precisely control the percussion force. There are also some percussion devices that can control the percussion force (such as patent CN213722098U), which generally use a spring in cooperation with a pull rod to control the force according to the degree of spring compression. However, the weight of their hammer heads is fixed, and for different parts of the patient, different hammer head weights are required. If the same percussion device is still used, it will cause examination errors. Summary of the Invention

[0004] The purpose of the present invention is to provide a percussion examination device for clinical neurology, and solve the following technical problems: the weights of the hammer heads of existing percussion devices are fixed, and different parts of the patient require different hammer head weights. If the same percussion device is still used, it will cause examination errors.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A percussion examination device for clinical neurology includes a cylinder body, a percussion rod movably arranged on the cylinder body, and a hammer head fixed at one end of the percussion rod. The hammer head is a hollow structure and is composed of a cylindrical end and a semi-circular end. A handle is fixed on the cylinder body. The handle is a cuboid hollow structure. A first pipe is connected to one side wall of the handle. A second pipe is movably arranged in the first pipe, and the end of the second pipe away from the first pipe is connected to the semi-circular end of the hammer head. A counterweight solution is provided inside the hammer head;

[0007] A blocking mechanism is arranged on the handle for blocking the connection between the first pipe and the handle.

[0008] As a further solution of the present invention: the blocking mechanism includes a movable rod movably arranged on the side wall of the handle. The movable rod is in an "L" shape. One end of the movable rod is fixed with a blocking block, and the other end is fixed with a pressing rod. The blocking block is located at the connection between the first pipe and the handle. A first spring is sleeved on the movable rod, and the first spring is located between the handle and the pressing rod.

[0009] As a further solution of the present invention: a piston rod is movably provided at the bottom of the handle, a piston plate is provided at one end of the piston rod, and a push-pull block is provided at the other end.

[0010] As a further solution of the present invention: a transparent observation window is provided on the side wall of the handle.

[0011] As a further solution of the present invention: a grip portion is sleeved on the outside of the handle, and an observation port is provided on the grip portion.

[0012] As a further solution of the present invention: the weight solution is an aqueous solution.

[0013] As a further solution of the present invention: a cavity connected to the hammer head is provided at one end of the knocking rod close to the hammer head, a second spring is connected in the cavity, a push block is connected to one end of the second spring, and the push block matches the inner cavity size of the cylindrical end of the hammer head.

[0014] As a further solution of the present invention: a movable block fixedly connected to the knocking rod is provided in the cylinder, a pull rod is connected to the side of the movable block away from the knocking rod, one end of the pull rod extends to the outside of the cylinder and is connected to a pull ring, a third spring is mounted on the pull rod, and the third spring is located inside the cylinder.

[0015] As a further solution of the present invention: a through hole is opened on the side wall of the cylinder along the length direction, and a scale is set on one side of the through hole. An L-shaped rod is also set in the through hole, one end of the L-shaped rod is fixedly connected to the movable block, and the other end is set with a pointer.

[0016] Beneficial effects of the present invention:

[0017] (1) The present invention sets the hammer head as a hollow structure. In the initial state, the hammer head is filled with a weight solution. When the weight of the hammer head needs to be reduced, the blocking mechanism can be adjusted to discharge part of the weight solution in the hammer head into the handle, thereby achieving the purpose of changing the weight of the hammer head and effectively inspecting organs in different parts.

[0018] (2) The present invention is provided with structures such as a pressing rod, a blocking block and a first spring. When in normal use, the doctor can perform a percussion examination by holding the handle. When the weight of the hammer head needs to be reduced, the pressing rod needs to be pressed, and the blocking block can be separated from the connection between the first pipe and the handle, thereby discharging the weight solution;

[0019] (3) The present invention provides a piston rod and a piston plate on the handle. When the weight solution enters the handle, the piston rod and the piston plate are driven to move downward, so that the doctor can intuitively see the change in the weight solution and more accurately control the weight of the hammer head. When the weight of the hammer head needs to be increased again, the piston rod is pushed upward to inject the weight solution into the hammer head again.

[0020] (4) The present invention provides a second spring and a push block. When the hammer head is filled with a weighted solution, the second spring is in a compressed state. The push block is located at one end close to the tapping rod. When the weighted solution decreases, the second spring pushes the push block to move, so that the weighted solution always remains in a squeezed state, thereby preventing the weighted solution from shaking in the hammer head and causing noise that affects the doctor's hearing of the tapping sound.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to Figure 1-2 As shown, the present invention is a percussion examination device for neurology clinical use, including a cylinder body 1, a percussion rod 2 movably arranged on the cylinder body 1, and a hammer head 3 fixed at one end of the percussion rod 2. The hammer head 3 is a hollow structure and is composed of a cylindrical end and a semi-circular end. A handle 4 is fixed on the cylinder body 1. The handle 4 is a cuboid hollow structure. A first pipe 6 is connected to one side wall of the handle 4. A second pipe 7 is movably arranged in the first pipe 6, and the end of the second pipe 7 away from the first pipe 6 is connected to the semi-circular end of the hammer head 3. A counterweight solution is arranged in the hammer head 3; a blocking mechanism is arranged on the handle 4 for blocking the connection between the first pipe 6 and the handle 4. The blocking mechanism includes a movable rod 8 movably arranged on the side wall of the handle 4. The movable rod 8 is in an "L" shape. A blocking block 10 is fixed at one end of the movable rod 8, and a pressing rod 9 is fixed at the other end. The blocking block 10 is located at the connection between the first pipe 6 and the handle 4. A first spring 11 is sleeved on the movable rod 8, and the first spring 11 is located between the handle 4 and the pressing rod 9; the hammer head 3 is a hollow structure. In the initial state, the hammer head is filled with the counterweight solution. When it is necessary to reduce the weight of the hammer head, the blocking mechanism can be adjusted to discharge part of the counterweight solution in the hammer head 3 into the handle 4, so as to achieve the purpose of changing the weight of the hammer head and effectively examining organs in different parts.

[0031] Refer to Figure 1-2 , a piston rod 12 is movably arranged at the bottom of the handle 4. A piston plate 13 is arranged at one end of the piston rod 12, and a push-pull block is arranged at the other end. A transparent observation window is arranged on the side wall of the handle 4. A hand-held part 5 is sleeved outside the handle 4, and an observation port is opened on the hand-held part 5. The counterweight solution is an aqueous solution; when the counterweight solution enters the handle 4, it will drive the piston rod 12 and the piston plate 13 to move downward, so that the doctor can directly see the change amount of the counterweight solution through the transparent observation window and more accurately control the weight of the hammer head 3. When it is necessary to increase the weight of the hammer head 3 again, the piston rod 12 is pushed upward, and the counterweight solution can be injected into the hammer head 3 again.

[0032] Refer to Figure 3A cavity connected to the hammer head 3 is provided at one end of the tapping rod 2 near the hammer head 3, and a second spring 14 is connected in the cavity. One end of the second spring 14 is connected to a push block 15, and the push block 15 matches the inner cavity size of the cylindrical end of the hammer head 3; when the hammer head 3 is filled with a counterweight solution, the second spring 14 is in a compressed state, and the push block 15 is located near one end of the tapping rod 2. When the counterweight solution is reduced, the second spring 14 will push the push block 15 to move, so that the counterweight solution always remains in a squeezed state, thereby avoiding the counterweight solution shaking in the hammer head 3 to cause sound and affect the doctor's hearing of the tapping sound.

[0033] See also Figure 1 , Figure 4 and Figure 5 A movable block 103 fixedly connected to the knock rod 2 is provided in the cylinder 1, and a pull rod 104 is connected to the side of the movable block 103 away from the knock rod 2. One end of the pull rod 104 extends to the outside of the cylinder 1 and is connected to a pull ring 105. A third spring 106 is mounted on the pull rod 104, and the third spring 106 is located inside the cylinder 1; a through hole 101 is opened on the side wall of the cylinder 1 along the length direction, and a scale 102 is provided on one side of the through hole 101, and an L-shaped rod 107 is also provided in the through hole 101, one end of the L-shaped rod 107 is fixedly connected to the movable block 103, and the other end is provided with a pointer 108.

[0034] The working principle of the present invention is as follows: initially, the hammer head 3 is filled with a weight solution, at which time the weight of the hammer head 3 is the largest, which is suitable for the examination of deep organs and tissues, such as the liver, spleen, etc., and can produce a dull sound, which is helpful for penetrating deeper tissue layers. The doctor holds the hand grip 5 with one hand and pulls the pull ring 105 with the other hand, which can drive the tapping rod 2 and the hammer head 3 to move toward the direction of the cylinder 1 and squeeze the third spring 106. The strength can be effectively adjusted by watching the scale 102. After the pull ring 105 is pulled to a suitable position, the pull ring 105 is released, and the hammer head 3 performs a tapping examination on the patient, generating corresponding sounds and vibrations, thereby judging the patient's organ status;

[0035] If the organs and tissues of medium depth are to be examined, a hammer head 3 of medium weight is required. At this time, the hand holding the hand grip 5 pulls the pressing rod 9 at the same time. The pressing rod 9 drives the movable rod 8 and the blocking block 10 to move and squeeze the first spring 11. The blocking block 10 leaves the connection between the first pipe 6 and the handle 4, and the counterweight solution in the hammer head 3 can enter the handle 4 through the second pipe 7 and the first pipe 6. The doctor can visually see the change in the counterweight solution through the transparent observation window. After half of the counterweight solution is discharged, the pressing rod 9 is released. Under the action of the first spring 11, the blocking block 10 is blocked again, and the organs and tissues of medium depth of the patient can be percussed for examination. The second pipe 7 and the first pipe 6 are movably connected and will not affect the movement of the hammer head 3. After the counterweight solution in the hammer head 3 is reduced, the second spring 14 will push the push block 15 to move, so that the counterweight solution is always kept in a squeezed state, thereby avoiding the counterweight solution shaking in the hammer head 3 during percussion to cause sound and affect the doctor's hearing of the percussion sound;

[0036] If you want to check superficial organs and tissues, such as lungs, heart, abdomen, etc., you need a light hammer head 3. Use the above operation method to discharge all the weight solution in the hammer head 3. At this time, the sound produced by the hammer head 3 is crisp, and the sound and vibration of organs and tissues can be clearly heard, which helps to capture subtle changes.

[0037] When it is necessary to fill the hammer head 3 with the weight solution again, the pressing rod 9 is pressed and the piston rod 12 is pushed upward at the same time, so that the weight solution can be injected into the hammer head 3 again. The operation is convenient and the applicability is high.

[0038] The above is a detailed description of an embodiment of the present invention, but the content is only a preferred embodiment of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the present invention should still fall within the scope of the patent coverage of the present invention.
