Description

Technical Field

[0001] This utility model relates to the field of medical devices, and in particular to a postoperative oral and maxillofacial cleaning device with adjustable water flow. Background Technology

[0002] Oral and maxillofacial surgery is a crucial discipline within clinical dentistry, encompassing dental and alveolar surgery, orthognathic surgery, temporomandibular joint surgery, and trauma. In my country, the scope of oral and maxillofacial surgery is broader, including not only oral surgical diseases but also maxillofacial plastic surgery, microsurgery, and head and neck tumor surgery. Post-operatively, wound cleaning is essential.

[0003] A search of Chinese patents revealed publication number CN220309223U, which describes a handheld oral irrigator for dental nurses. However, this irrigator cleans the oral cavity using a brush head and water spray, requiring constant hand movement during the cleaning process. This hand-operated cleaning method is inefficient and produces poor cleaning results, leading to a heavy workload, low efficiency, and inconvenience in use and brush head replacement. Since brush heads are typically connected by threads, replacement requires repeated rotation, which is cumbersome, increases workload, and reduces replacement efficiency. To address these issues, we propose an adjustable water flow post-operative oral and maxillofacial irrigator. Utility Model Content

The cleaning process can be adjusted using the button. The flow rate of the water pump 21 can be adjusted to regulate the rinsing flow rate. Rotating the rotating ring 12 causes the triangular block 13 to rotate, which in turn moves the slide rod 14. The slide rod 14 then moves the locking rod 16, disengaging it from the locking groove 17. The brush head is then removed and replaced. The cleaning tube 11 on the new brush head is attached to the movable tube 9. Under the action of the spring 15, the slide rod 14 drives the locking rod 16 to engage with the locking groove 17, thus fixing it in place and completing the replacement.
