Technical Field

[0001] This utility model belongs to the field of medical devices, and specifically relates to a retractor for the lips and tongue. Background Technology

[0002] In routine dental care, surgery, and imaging, it is necessary to fully expose the surgical field and effectively isolate soft tissues such as the tongue, buccal mucosa, and floor of the mouth to prevent them from interfering with the procedure, contaminating the surgical area, or being accidentally injured by instruments.

[0003] In existing technologies, when performing procedures requiring panoramic exposure, doctors or assistants typically need to use multiple retractors simultaneously, or the assistant must manually pull them. This not only consumes human resources but also makes it difficult to guarantee traction strength and stability, increasing patient discomfort and surgical difficulty. Furthermore, most existing retractors are divided into left and right sides, making instrument management and selection inconvenient. At the same time, existing retractors cannot replace individual parts, resulting in resource waste. If a part of the retractor is damaged, the entire set of retractors must be scrapped because the faulty part cannot be replaced individually. This increases the cost of consumable procurement and exacerbates the idleness and waste of medical resources. Especially when instrument inventory is tight, it may further affect the normal progress of the diagnosis and treatment process. Utility Model Content
