Abstract

一种栓齿式阴道扩张器,由手柄、按柄、齿条构成,齿条穿过手柄固定在按柄上,齿向上。使用时,压紧手柄,上顶齿条,凹槽的凸处卡入齿槽,张合头张开。抽出时,下压齿条,齿条落入凹槽底,张合头自然闭合。本实用新型结构简单、可调性好、固定牢靠、使用极为方便,适于各医疗卫生部门使用。

Description

一种栓齿式阴道扩张器
本实用新型涉及一种适于妇科医生使用的阴道扩张器。
现在普遍采用的阴道扩张器,是由螺杆和螺母的配合来限定扩张器张合开合的程度,使用者操作时,必须一手按压手柄,一手旋动螺母,极不方便。《快速开合式阴道扩张器》(公告号2079057),为将双手操作改为单手操作,特用齿条代替了螺杆、螺母,齿条穿过手柄通过支点固定在按柄上。此扩张器相对于前者要方便些,但却存在以下问题:齿条只2至3个齿,齿朝下布置,使用时,利用齿条的重力由齿将手柄卡住,使扩张器张开。需手柄复位时,则需将齿条上抬,使其脱开手柄。上抬动作必须始终进行,否则在抽出过程中,可能再因齿条的重力作用下卡,张合头又张开,影响抽出动作。
本实用新型的目的旨在提供一种新的栓齿式阴道扩张器,扩张器结合简单、可调性好、固定牢靠、使用极为方便。
本实用新型的目的是以下述方式实现的,一种栓齿式阴道扩张器,由手柄1、按柄2、齿条3构成,齿条穿过手柄,通过支点5固定在按柄上。齿条齿向上,尾端有一大于齿的端头4,穿过齿条的凹槽6呈
Figure Y9421351200031
形,上部凹处与端头4相吻合,上部凸处与齿槽相吻合。
附图为本实用新型结构示意图。
参照附图,使用本实用新型时,将闭合态的阴道扩张器张合头插进阴道,压紧手柄1使张合头扩张到所需角度时,上顶齿条,则凹槽6上的凸处卡入齿槽内,再加上阴道壁的挤压作用,使其固定牢固。需抽出时,只需下压齿条,由于齿条的重力作用,则齿条落入凹槽槽底,张合头自然闭合,不会有任何误动作产生,且也不用始终费力上抬齿条。一直向内推齿条,齿条端头4可卡入凹槽6上部凹处。
本实用新型结构简单、可调性好、固定牢靠、使用极为方便,适于各医疗卫生部门使用。
