AI Technical Summary
Existing percussion hammers typically only come in one type of hammer head, which makes it difficult to meet the diverse needs of different patient groups (such as newborns, toddlers, and school-aged children) and different percussion sites (such as the chest, abdomen, and limb joints), resulting in poor adaptability.
A percussion hammer with multiple sizes of hammerheads was designed. The hammerheads can be quickly replaced and stably fixed through a rotating component and a positioning component. The hammerheads include a neonatal soft touch head, a small rubber hammerhead, a medium rubber hammerhead, and a large rubber hammerhead. The hammerheads can be easily switched using a knob and threaded rod system, and the stability of the hammerheads during the percussion process is ensured by the cooperation of a helical spring and a positioning block.
It enables rapid replacement of the hammer head according to the needs of different patient groups and percussion sites, improving the stability and accuracy of percussion operations and meeting diverse examination needs.
