Technical Field
[0001] This utility model relates to the field of pulse debridement gun technology, and in particular to a disposable pulse debridement gun with a reusable battery. Background Technology
[0002] A disposable pulse debridement gun is a disposable irrigation system that provides simultaneous pulse irrigation and aspiration. After treatment, the irrigation fluid becomes a liquid flow with a specific frequency and jet force, capable of thoroughly rinsing wounds, superficial tissues, and bone marrow cavities. It is easy to operate and effectively cleans impurities, bacteria, tissue debris, and blood from wounds while minimizing secondary damage to surrounding healthy tissues, thus reducing the probability of infection. For example, a Chinese patent discloses a disposable medical pulse debridement gun with an LED light (application number CN202020724856.4). When the irrigation fluid splashes onto the collection bag, obstructing the view, the LED light can be turned on via a control switch to enhance wound observation, allowing the debrider to determine whether debridement is complete, saving time and cost. However, this gun directly secures the battery with a clip, which can cause the battery to shake during cleaning, potentially leading to a short circuit and affecting the normal operation of the device.
