The utility model discloses a protective and expanding device for oral surgery, which comprises a tube body, an inner supporting ring, an outer supporting ring and a supporting plate. The inner supporting ring is installed at one end of the tube body, and the outer supporting ring is installed at the other end of the tube body. The tube wall of the tube body forms a groove with the inner supporting ring and the outer supporting ring. The inner supporting ring, the tube body and the outer supporting ring are provided with a through hole, and the edge of the inner supporting ring is provided. Bending edge, supporting plate is two and connected with bending edge respectively. The tube body, inner supporting ring, outer supporting ring, bending edge and supporting plate are all made of elastic material. Through the above-mentioned settings, the friction between instruments and doctors'hands on patients' bilateral oral horns during oral surgery can be avoided, the pressure on bilateral oral horns can be reduced, and the incidence of postoperative keratitis and even oral horn erosion can be reduced. It can also play the role of expanding the field of operation, enlarging the operating space of doctors, and reducing the difficulty of operation. It can also protect the oral mucosa and lip skin, so as to avoid it. The device is easy to operate and comfortable to wear.
【技术实现步骤摘要】
口腔手术防护和扩口装置
本技术涉及医疗器具,特别涉及一种口腔手术防护和扩口装置。
技术介绍
现有的口腔手术过程中没有相应的防护装置,手术过程中医生手术器械压迫和摩擦,容易摩擦到嘴周围,导致患者嘴角炎,甚至嘴角糜烂,据统计,口腔腭裂手术中不对患者口腔进行保护,术后口角炎的发生率为99.2%。现有还有一种降低对患者嘴角摩擦的方法,在嘴周围涂抹青霉素或者是红霉素眼膏,既起到消炎,又能起到润滑降低磨损的作用,但手术过程中隔几分钟就要涂抹一次,而且涂抹过程中要中断手术,阻断了手术的连贯性,也增加了手术的时间,有研究分析证明手术时间长是口腔手术术后发生口角炎重要危险因素,所以尽量缩短手术时间能降低口角炎发生率。
技术实现思路
本技术的目的在于提供一种口腔手术防护和扩口装置,以解决现有技术中存在的上述技术问题。本技术提供的口腔手术防护和扩口装置,包括管体、内支撑环、外支撑环和支撑板,所述内支撑环安装在所述管体一端,所述外支撑环安装在所述管体另一端,所述管体的管壁与所述内支撑环和所述外支撑环形成凹槽,所述内支撑环、管体和外支撑环设有相贯通的通孔,所述内支撑环的边缘设有弯边,所述支撑板为两个并分别与所述弯边连接,所述管体、内支撑环、外支撑环、弯边和支撑板均采用弹性材料制成。进一步地,所述内支撑环与所述管体一端为一体结构,所述外支撑环与所述管体另一端为一体结构。进一步地,所述弯边与所述内支撑环为一体结构,所述支撑板与所述弯边为一体结构。进一步地,所述支撑板的边缘分别安装有硬框。进一步地,所述通孔为椭圆形通孔、圆形通孔或长方形通孔。进一步地,所述管体的管壁上安装有两个防护垫,两个所述防 ...
