Trochanter expander for protecting oral soft tissue and mucous membrane from chemical and mechanical stimulation

摘要

A useful model is medicine,It can be used to improve the field of vision and protect oral soft tissue from various injuries. The rotary expander isThe inner frame (1) is round, and the flexible plate (2) and the outer frame (3) are round. The left and right inner frames (g) continue from the inside to protect the buccal mucosaThis is a flat elastic plate (4),A tongue tip holder (5) is installed between them as a curved band extension (6). Expansion (6) front wide, top wide,It also covers the upper surface of the tongue. The holder (5) has a rectangular part (7),Connecting it to the inner surface (4) of the elastic plate,The ends of these parts are rigidly attached to the inner frame (1). The upper lip tubercle was resected in the upper vestibular region. technological achievementsThe purpose of the model is to improve the manufacturability of the equipment, keep the oral soft tissue fully insulated, and protect it from mechanical and chemical factors Substance. 2 liters.
