Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a percussion device for clinical neurology which is easy to adjust. Background Art

[0002] Nerve reflex is the basic mode of human life activities; once the nervous system is faulty, pathological reflex will occur; pathological reflex refers to abnormal reflex that occurs when the central nervous system is damaged; percussion hammer is an instrument used by doctors to check neuromuscular reflexes. For example, when checking the patient's knee reflex, the patient is asked to sit with his feet suspended in the air and relaxed, and the doctor taps the knee with a percussion hammer; in normal people, it will cause the quadriceps (a muscle in the front of the thigh) to contract and the calf to rise; this reflex is called knee tendon reflex; the center of knee tendon reflex is in the spinal cord; or it can be used to detect the patient's internal organ reflexes, such as kidney stones and other problems, so it is a commonly used detection tool for doctors;

[0003] The existing percussion hammers are similar in function and appearance, but due to different patient populations and different percussion locations, doctors need different forces for percussion. At the same time, the affected parts of patients have different reactions due to the lesions. Therefore, it is often difficult to control the force during actual operation, which can easily cause the patient to be too painful or react too violently, which can easily lead to misjudgment by the doctor. Therefore, it is particularly necessary to switch the hammer mode. For this reason, we have proposed a percussion device for clinical neurology that is easy to adjust. Utility Model Content

[0028] A clamping handle 3 is provided on the upper left side of the handle 1, and a waist-shaped groove is provided on the upper part of the handle 1 near the mounting shell 5, and the clamping handle 3 is rotatably mounted on the waist-shaped groove through a screw shaft;

[0029] A clamping handle spring 4 is installed between the lower part of the clamping handle 3 and the handle 1, and the top of the handle 1 is fixedly connected to the bottom of the mounting shell 5; a guide joint 8 is provided on the top of the handle 1, and the guide joint 8 is upwardly inserted into the inner cavity of the mounting shell 5;

[0030] The cavity of the guide joint 8 is connected vertically and communicates with the inner cavities of the mounting shell 5 and the handle 1 respectively;

[0031] A striking head 7 is fixed to the left end of the mounting shell 5. The striking head 7 is a plastic silicone ball, and the inner cavity of the striking head 7 is hollow.

[0032] An adjusting chamber 11 is provided on the left side of the inner cavity of the mounting shell 5. A filling ball 9 is installed on the left side of the adjusting chamber 11. The filling ball 9 is a solid rubber ball. The filling ball 9 is hemispherical and is filled in the inner cavity of the striking head 7 to the left.

[0033] A fixing plate 10 is provided on the right side of the filling ball 9, a hook is provided on the right side of the fixing plate 10, and a steel wire rope 13 is connected to the hook;

[0034] A filling ball spring 12 is also provided in the adjusting chamber 11, the right end of the filling ball spring 12 abuts against the side wall of the adjusting chamber 11, and the steel wire rope 13 is transversely connected to the middle of the filling ball spring 12;

[0035] The top and bottom of the fixing plate 10 are both provided with sliding edges, and the sliding edges are slidably abutted against the side wall of the adjustment cavity 11;

[0036] The right side of the mounting shell 5 is penetrated by a mounting shell rotating shaft 6, which is rotatably mounted and perpendicular to the lateral extension direction of the steel wire rope 13;

[0037] A limit rotation shaft 14 is arranged in the inner cavity of the handle 1 near the clamping handle spring 4, and the limit rotation shaft 14 is perpendicular to the mounting shell rotation shaft 6;

[0038] The steel wire rope 13 is wound around the mounting housing shaft 6 and then passes through the guide joint 8 downwards. After being wound around the limit shaft 14 downwards, it is fixedly connected to the clamp handle 3 to the left.

[0039] The front and rear ends of the mounting housing shaft 6 are provided with limiting wheels, and the limiting wheels are respectively located on the front and rear sides of the mounting housing 5;

[0040] When using this solution, the clamp handle 3 is pinched with fingers, the clamp handle 3 presses the clamp handle spring 4 inward, and the wire rope 13 connected to the clamp handle 3 is released upward at the same time, and the filling ball 9 is pushed to the left under the release of the wire rope 13;

[0041] Furthermore, since the clamp handle 4 contracts the filling ball spring 12 inwardly when in the initial position, when the steel wire rope 13 is released upward, the filling ball spring 12 pushes the filling ball 9 to the left;

[0042] Furthermore, the filling ball 9 is pushed to the left and abuts against the inner cavity of the striking head 7 to complete the filling, and the striking head 7 is transformed from hollow to solid;

[0043] Furthermore, usually due to the different patient populations and the different knocking positions, doctors need different forces for knocking. At the same time, the affected parts of patients have different reactions due to the lesions. Therefore, it is often difficult to control the force during the actual operation. The knocking device in this solution can switch between two modes. When the knocking head 7 is hollow, the weight of its front end is lighter, and the pain at the knocking point is better, which is suitable for knocking on reaction areas with less fat layers such as joints. The reaction areas here are relatively shallow and not suitable for gravity knocking. When the filling ball 9 is filled into the inner cavity of the knocking head 7, the weight of the knocking head 7 becomes heavier, and the pain at the knocking point is heavier, which is more suitable for knocking on the reaction areas of the waist and abdomen. The fat layer here is relatively thick, and the feedback during knocking is more obvious.

[0044] Furthermore, in the present solution, the elastic force of the clamp handle spring 4 is greater than the filling ball spring 12, and the end weight of the striking head 7 can be flexibly adjusted to adapt to the fat layer in the reaction zone, which is very convenient.
