【技术实现步骤摘要】
一种包皮切割吻合器的龟头罩、丝杆组件
本技术涉及的是一种包皮切割吻合器的龟头罩、丝杆组件,适用于作男性因包皮过长,或包茎进行包皮环切的吻合手术器械。
技术介绍
目前,包皮切割吻合器的龟头罩和丝杆,普遍采用一体式结构,加工比较困难,成本高,结患者增加经济负担。另外有一种龟头罩与丝杆组件采用塑料件注塑而成,结构强度差,会影响包皮切割吻合手术质量。
技术实现思路
本技术目的是针对上述不足之处提供一种包皮切割吻合器的龟头罩、丝杆组件,龟头罩和丝杆为分体结构,采用连接卡块、连接定位卡槽和连接销连接。龟头罩采用锌合金整体压注制成,强度高,在手术过程中不会出现断裂现象。吻合钉成型完美,稳定性好,止血效果佳,吻钉术后自然脱落,吻切时切割整齐,避免出现撕裂现象。一种包皮切割吻合器的龟头罩、丝杆组件是采取以下技术方案实现的:一种包皮切割吻合器的龟头罩、丝杆组件包括龟头罩、注塑连接块和丝杆。龟头罩具有龟头罩体,龟头罩体后部设置有龟头罩连接杆,龟头罩连接杆前端设置有防滑槽,使用时便于捆扎包皮组织,防止打滑,龟头罩连接杆后端设置有连接卡块,连接卡块与防滑槽之间设置有注塑台阶,便于注塑连接块注塑 ...
