Description

Technical Field

[0001] The invention relates to the technical field of percussion hammers, in particular to a percussion hammer for diagnosing and treating rheumatic bone diseases. Background Art

[0002] When the doctor uses a percussion hammer to tap the patient's joints, bones and other parts, the hammer head contacts the body and transmits force. For patients with rheumatic bone diseases, the state of the bones and periarticular tissues (such as synovium, ligaments, etc.) at the affected part will change. The vibration feedback of normal tissue under percussion is different from that of diseased tissue. Through moderate percussion with a percussion hammer, the doctor can feel and distinguish the amplitude, frequency, duration and other characteristics of the vibration. For example, the vibration transmission of healthy joints is relatively regular after percussion, while the vibration of the joints of patients with rheumatoid arthritis will become dull, irregular or the amplitude of the vibration will be smaller due to inflammation leading to joint effusion and synovial hyperplasia. This feedback can help doctors judge the extent of the lesion, such as the severity of bone destruction, soft tissue swelling, etc., and provide a basis for the diagnosis of rheumatic bone diseases. For example, a medical percussion hammer disclosed in announcement number CN110974308B includes a main body, a hammer head assembly and a stripping assembly. The main body includes a hammer handle, a crank arm, a top plate and a hammer core, and the hammer core and the hammer handle are perpendicular to each other; the hammer head assembly is composed of a core tube and a plurality of disposable hammer sleeves, the core tube can be fixedly sleeved outside the hammer core, and the disposable hammer sleeves are tightly sleeved outside the core tube in order from small to large; the stripping assembly includes a push rod, a cutter and a suction cup, which are used to cut an opening in a part of the upper end of the outermost disposable hammer sleeve and lift the corners on both sides of the opening. During clinical use, the outermost disposable hammer cover can be peeled off by using the peeling component, and percussion can be performed with the help of a new disposable hammer cover. One patient uses one disposable hammer cover, thereby reducing the risk of cross infection to a minimum without significantly affecting the diagnostic efficiency. The medical percussion hammer has a scientific structure, is convenient and fast to use, is easy to use, can ensure the percussion effect, and has a broad promotion prospect.

[0003] The percussion hammer in the prior art can meet the needs of use. However, when in use, due to the different locations of the patient's illness, the doctor needs to use the percussion hammer to knock on different locations for penetration. However, the existing hammer head is relatively single and cannot perform multiple knocks on a single location for penetration. In addition, the force areas of the hammer head when knocking on the patient are different, and the reactions when knocking are also different. In addition, the hammer head is not easy to replace. If the hammer head is damaged and the entire hammer cannot be used, it is undoubtedly a waste of resources and increases costs. Summary of the invention

[0037] Working principle: During operation, when the angle of the hammer head 3 needs to be adjusted, only one hand needs to hold the outer wall of the upper handle 14, and the other hand needs to hold the fixing ring 131 and push it upward. When the fixing ring 131 is pushed upward, the lower rack plate 133 provided at the bottom end of the fixing ring 131 engages with the one-way gear 125 provided on the inner side of the side plate 122 to rotate to provide stability, and the half rack plate 134 fixed at the top end of the fixing ring 131 moves upward through the partition block 140 to engage with the first rotating shaft 143 inserted into the lower rack plate 133. The lower gear 144 rotates, and the lower gear 144 rotates to engage with the upper gear 146 at the top to rotate in the second rotating shaft 145. The upper gear 145 rotates to engage with the half gear 22 installed at the bottom side of the top flip block 211 to rotate. The rotation of the half gear 22 can drive the flip block 211 to flip upward under the limit of the fixed rotating shaft 212 inserted in the center, and can drive the hammer head 3 installed at the front end to flip upward at a certain angle. Similarly, the fixing ring 131 can be pulled downward to make the hammer head 3 flip downward.

[0038] When the hammer head 3 needs to be replaced, it is only necessary to pull the fixing ring 131 downward to the bottom end. When the fixing ring 131 drops to the bottom side, the half rack plate 134 can mesh with the lower gear 144 and rotate in the opposite direction to drive the upper gear 146 to drive the half gear 22 to rotate in the opposite direction. The reverse rotation of the half gear 22 can drive the flip block 211 to rotate downward. When the flip block 211 drops, the triangular block 248 at the bottom contacts the bottom end of the adjusting box 21, which can push the triangular block 248 and the vertical plates 247 on both sides of the top to rise. The rising of the vertical plates 247 can push the connecting plate 24 at the top 2 rises under the elastic force of the spring 243, and the connecting plate 243 can slide in the vertical rod 245 through the protruding blocks 244 provided on both sides to prevent the spring 243 from squeezing and causing deviation. When the connecting plate 242 rises, it can drive the clamping block 246 to rise, and the clamping block 246 rises to be separated from the square groove 33 opened on the top of the hammer block 31. When the flip block 211 is tilted, the hammer head 3 can slide out of the insertion groove 213. Then, after the new hammer head 3 to be replaced is reinserted into the insertion groove 213 inside the flip block 211, the fixing ring 131 is held and pushed to the center position.
