[0002] Neurology is a secondary discipline related to nerves. It does not belong to the concept of internal medicine. It mainly treats cerebrovascular diseases, migraines, inflammatory brain diseases, myelitis, epilepsy, dementia, metabolic diseases and genetic diseases, trigeminal neuralgia, sciatica, peripheral neuropathy and myasthenia gravis, etc. The percussion device is an instrument used by doctors to check neuromuscular reflexes during clinical treatment in neurology. Among them, the percussion hammer is a more commonly used percussion device. The percussion hammer is mostly composed of a piece of rubber and a wooden or metal handle. When used, the rubber end is gently tapped on the relevant part to observe the neuromuscular reflex.

However, since the individual percussion force is different, there are certain differences when the medical staff use different percussion forces to test the knee reaction. As a result, it may not be possible to record the reactions to different percussion forces more accurately. Therefore, in response to the above problems, we designed a knee percussion device.

DETAILED DESCRIPTION
[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0026] See also Figures 1 to 7In the embodiment of the utility model, a knee percussion device comprises an outer shell 1, characterized in that a circular groove 2 is arranged inside the outer shell 1, a sliding shell 3 is slidably connected inside the circular groove 2, a percussion head 4 is screwed and connected to the front side of the sliding shell 3, and a telescopic rod 5 is arranged on the upper and lower sides of the rear side of the sliding shell 3, one end of the telescopic rod 5 is fixedly connected to the rear outer wall of the sliding shell 3, and the other end of the telescopic rod 5 is fixedly connected to the inner rear side of the circular groove 2, a spring 6 is arranged on the outer wall of the telescopic rod 5, one end of the spring 6 is connected to the outer wall of the sliding shell 3, and the other end of the spring 6 is connected to the inner side surface of the circular groove 2, force adjustment components 7 are arranged on both sides of the outer shell 1, a limiting groove 8 is arranged on the front bottom surface of the outer shell 1, and a limiting block 9 is fixedly connected to the limiting groove 8 on the outer wall of the bottom surface of the sliding shell 3, and a pressing plate 10 is fixedly connected to the bottom end of the limiting block 9, and a receiving seat 11 is fixedly connected to the rear bottom surface of the outer shell 1, and a long connecting handle 12 is arranged in the middle part of the receiving seat 11.
[0027] In specific implementation, through the coordinated arrangement of the outer shell 1, the circular groove 2, the sliding shell 3, the knocking head 4, the telescopic rod 5, the spring 1 6, the limit groove 8, the limit block 9, the pressure plate 10 and the force adjustment component 7, when the medical staff uses the knocking head 4 to knock on the patient's knee, the strength does not need to be controlled by the medical staff themselves, and the knocking size can be adjusted to avoid the phenomenon of recording deviation caused by the influence of the medical staff's personal strength feeling, thereby facilitating the medical staff to record the patient's response to different knocking strengths more accurately later. When in use, after adjusting the strength, the knocking head 4 is aimed at the knee that touches the patient to be tested, and by pressing The movable pressure plate 10, when the pressure plate 10 drives the sliding shell 3 to move backward through the limit block 9 and touches the receiving rod 75 in the force adjustment component 7, the pressed pressure plate 10 is released, so that the sliding shell 3 drives the knocking head 4 to rebound under the action of the spring 6 on the outside of the telescopic rod 5, thereby performing a knocking test on the patient's knee. The knocking force becomes greater when the sliding shell 3 moves further back. The receiving seat 11 and the long connecting handle 12 are provided to facilitate medical staff to hold the knocking device. The screwing arrangement of the knocking head 4 and the sliding shell 3 makes it convenient for subsequent medical staff to replace and clean the knocking head 4, thereby better avoiding the situation where the knocking head 4 is used continuously and causes cross infection.
[0028] Embodiment 1
[0029] like Figures 3 to 5As shown, in this embodiment, a reference plate 13 is fixedly connected to one side of the outer wall of the outer shell 1, and the force adjustment component 7 includes a movable groove 71, a rack plate 1 72 is fixedly connected to the inner bottom side of the movable groove 71, and a plurality of springs 2 73 are fixedly connected to the inner top side of the movable groove 71, and the bottom ends of the plurality of springs 2 73 are fixedly connected to the rack plate 2 74, and a tooth block 76 is meshingly connected between one end of the spring 2 73 and the rack plate 1 72, and a receiving rod 75 is fixedly connected to the adjacent sides of the two tooth blocks 76, and a torsion block 77 is fixedly connected to one end of the receiving rod 75, and a ring plate 14 is movably sleeved on the outer wall of the side of the receiving rod 75 close to the torsion block 77, and a pointing plate 15 corresponding to the reference plate 13 is fixedly connected to the bottom outer wall of the ring plate 14.
[0030] In specific implementation, when it is necessary to adjust the striking and pulling force of the striking head 4, the torsion block 77 is used to drive the receiving rod 75 to rotate, so that the receiving rod 75 drives the tooth block 76 to move along the rack plate 1 72, thereby adjusting the position of the receiving rod 75. Through the cooperation of the rack plate 2 74 and the plurality of springs 2 73, the tooth block 76 can be limited in the absence of external force rotation, thereby preventing the tooth block 76 from moving by itself. Through the coordinated arrangement of the ring plate 14, the pointing plate 15 and the mark plate 13, it is convenient for medical staff to identify the adjustment position and record different forces, which is convenient for medical staff to detect and check.
[0031] Embodiment 2
[0032] like Figure 6 , 7 As shown, in the present embodiment, a receiving ring shell 16 is fixedly connected to the upper inner part of the long connecting handle 12, and a plurality of arc-shaped clamping strips 17 are fixedly connected to the inner side surface of the receiving ring shell 16 at equal intervals, and circular connecting blocks 18 are fixedly connected to both sides of the outer wall of the receiving seat 11, and an adapter shell 19 is fixedly connected to the adjacent ends of the two circular connecting blocks 18, and a plurality of elastic strips 20 are fixedly connected to the inner wall of the adapter shell 19 at equal intervals, and an arc-shaped clamping groove 21 is provided on the middle side of the outer wall of the elastic strip 20, and the arc-shaped clamping groove 21 is slidably clamped with the arc-shaped clamping strip 17, and a protective soft cover 22 is slidably sleeved on the outer wall of the long connecting handle 12.
[0033] In specific implementation, when the knocking device needs to be stored and placed, the long connecting handle 12 is rotated so that the arc-shaped clamping strip 17 in the receiving ring shell 16 on the long connecting handle 12 rotates along the elastic strip plate 20 on the adapter shell 19. Due to the elastic setting of the elastic strip plate 20, when the arc-shaped clamping strip 17 is not inserted into the arc-shaped clamping groove 21 during rotation, the elastic strip plate 20 will be pressed inward to allow the arc-shaped clamping strip 17 to pass through. When the arc-shaped clamping strip 17 is inserted into the arc-shaped clamping groove 21, the long connecting handle 12 itself will not rotate without the action of external rotation, so that the long connecting handle 12 can be rotated and engaged. The protective soft cover 22 is provided to increase the comfort of the grip of the long connecting handle 12. This design saves placement space and has a certain practical effect.
