The utility model relates to the technical field of medical devices, in particular to a new type of vaginal dilator for gynecological clinical examination, which comprises a U-shaped handle, a screw rod, a L-shaped rod, an upper expansion plate, a lower expansion plate, an upper pull box, a lower pull box and a thread adjusting cylinder. The upper end of the U-shaped handle is fixedly connected with a lower pull box, the upper and lower sides of the thread adjusting cylinder are screwed with a thread rod, and the guide cylinder is movable The L-shaped guide rod is inserted, and the upper end of the L-shaped guide rod on the left and right sides is fixedly connected with an upper pull box. The upper and lower expansion plates are duck beak shaped, and their ends are fixedly connected with push plates perpendicular to them. The two push plates are respectively inserted in the upper pull box and the lower pull box and fixed by two fixing bolts. The utility model has the advantages of reasonable structure design, wide field of vision after the vagina is expanded, self-locking at any time after the vagina is expanded, simple and convenient operation, time-saving and labor-saving, convenient installation and replacement, low cost, and worth popularizing and using.
【技术实现步骤摘要】
一种妇科临床检查用新型扩阴器
本技术涉及医用器械
,尤其是一种妇科临床检查用新型扩阴器。
技术介绍
扩阴器也称为阴道扩张器等,主要由上下两页鸭嘴形扩张片以及扩张装置组成,主要用于妇科常规检查、手术。传统的扩阴器扩张装置位于上下扩张板的后端,开口较小会遮挡视线,影响了检查的视野或术野,而且扩张后锁定不便,操作繁琐,给检查和手术带来不便。
技术实现思路
本技术的目的是为了克服上述技术缺点提供一种妇科临床检查用新型扩阴器。本技术结构设计合理,阴道扩张撑开后视野宽广,扩张后可随时自行锁定,操作简单方便,省时省力,便于安装更换,成本低,值得推广使用。本技术解决技术问题采用的技术方案为:一种妇科临床检查用新型扩阴器,包括U形柄、丝杆、L形杆、上扩张板、下扩张板、上牵拉盒、下牵拉盒、螺纹调节筒,所述U形柄的上端固定连接有下牵拉盒,U形柄的两侧支杆上设有左右贯通的滑动槽,螺纹调节筒的上下两侧均螺接固定有螺纹杆,上下两侧的螺纹杆螺向相反,下侧的螺纹杆下端端部固定连接在U形柄的下侧弧形部中部内壁上,上侧的螺纹杆上端端部固定连接有与其垂直的牵拉螺纹筒,所述下牵拉盒两侧中部固定连接有连接杆,连接杆的外侧端部固定连接有导向筒,导向筒内均活动插接有L形导向杆,L形导向杆的下端端部均螺接固定有T形螺纹筒,两侧的T形螺纹筒之间螺接固定有丝杆,丝杆穿过两侧的滑动槽且其中部与牵拉螺纹筒螺接固定,左右两侧的L形导向杆的上端端部之间固定连接有上牵拉盒,上扩张板和下扩张板均为鸭嘴形且其端部均固定连接有与其垂直的推板,两个推板分别插接在上牵拉盒和下牵拉盒内且通过两个固定螺栓螺接固定。使用时,上扩张 ...
