Abstract

本发明涉及一种在医学临床中治疗痔疮、直肠黏膜脱垂的一种痔上黏膜枯切的无钉吻合器器械。其原理为：利用聚羟基乙酸、硫酸钡和其他医用高分子材料制成环形吻合器底环和套环及紧环器手柄装置；通过把痔上黏膜组织拉入吻合器底环和套环之间，利用紧环器手柄在通过调节吻合器底环和套环拉紧之间距离后进行吻合。适用于痔疮的微创性手术治疗。弥补原吻合器的术后人体组织内植入金属钉带来的多种缺陷。

Description

无钉吻合器
所属技术领域
本发明涉及一种在医学临床中治疗痔疮、直肠黏膜脱垂的一种痔上黏膜枯切的无钉吻合器器械。 
技术背景
1975年，Thomson提出了“肛垫”学说，推动了人们对痔的重新认识，也带动了痔的治疗方法的变革，尽可能保护肛垫功能已形成共识。在治疗痔的众多方法中，PPH手术最具革命性
目前临床广泛应用PPH吻合器存在的缺陷：1.手术中固定的肛管镜需要用针线缝合固定，对人体有创伤；2.环切后环状吻合口内有金属钉遗留环状狭窄环，导致大便变细，甚至排便障碍。
发明内容
针对当前PPH器械的缺陷，研制设计一种痔上黏膜枯切的无钉吻合器。其原理为：利用聚羟基乙酸、硫酸钡制成环形吻合器底环和套环及紧环器手柄装置；利用荷包线把痔上黏膜组织拉入吻合器底环和套环之间，利用紧环器手柄在通过调节吻合器底环和套环拉近之间距离后进行吻合。适用于痔疮的微创性手术治疗。弥补原吻合器的术后人体组织内植入金属钉带来的多种缺陷。
附图说明
下面结合附图和实施例对本发明进一步说明

图2：是吻合器底环的示意图
图3：是套环示意图
图4：是套紧器手柄示意图

具体实施方式
使用时在适配肛门镜下或直接把吻合器底环（1）根据病理情况放入到痔上黏膜适当位置处，利用荷包线把痔上黏膜组织拉入吻合器底环和套环（5）之间的吻合腔（2、7），利用套紧器手柄（8）在通过调节吻合器底环齿轮螺丝（3、4）和套环内齿内螺丝（6）拉紧之间距离后进行吻合。适用于痔疮的微创性手术治疗。

Claims (3)

1.一种无钉吻合器，由吻合器底环、套环、、吻合腔、套紧齿轮螺丝、套紧器手柄组成，其特征是：利用套紧器手柄通过调节吻合器底环齿轮螺丝和套环内齿内螺丝拉紧之间距离后进行吻合。
2.根据权利1所述无钉吻合器，其特征是：吻合器底环、套环由聚羟基乙酸、硫酸钡制作。
