Description

一种口腔支撑钳
技术领域
本实用新型涉及一种医疗器械,尤其为一种口腔支撑钳。
背景技术
在医院口腔、牙科的检查、治疗过程中,包括填充、开髓、切髓、干髓、根管治疗、塑化治疗、洗牙等,需要借助口腔支撑装置来扩张口部。目前使用的口腔支撑钳扩张口部时,钳柄位于口部正前方,遮挡医生的视线,不便医生进行手术操作。
实用新型内容
为克服上述技术问题,本实用新型提供了一种扩张效果好、结构简单的口腔支撑钳。
为实现上述技术目的,本实用新型是采用以下技术方案实现的:一种口腔支撑钳,包括两个铰接杆,铰接杆通过固定轴铰接在一块,铰接杆的后端设有指环,固定轴与指环之间的铰接杆处设有一个定位杆,另一铰接杆上设有定位套,两个铰接杆的前端分别设有向同一侧弯折拐角,拐角上分别设有支撑体。
本实用新型和以往技术相比,具有以下有益效果:结构简单,实用方便,扩张口腔时铰接杆不会遮挡视线,以便医务人员顺利的完成口腔治疗。
附图说明
附图为本实用新型结构示意图。
图中,1、支撑体,2、铰接杆,3、固定轴,4、指环,5、定位杆,6、定位套,7、拐角。
具体实施方式
参看附图,铰接杆2通过固定轴3铰接在一块,铰接杆2的后端设有指环4,固定轴3与指环4之间的铰接杆2处设有一个定位杆5,另一铰接杆2上设有定位套6,两个铰接杆2的前端分别设有向同一侧弯折拐角7,拐角7上分别设有支撑体1。
