Abstract

本实用新型公开了一种腹腔镜针式单曲超声刀头,它包括超声刀头本体,超声刀头的前端向下弯曲,弯曲端长度为3~8cm,弯曲弧度为120~150°。由于折弯的作用,使钩部有3~8cm半径的活动范围,便于施术者操作。

Description

腹腔镜针式单曲超声刀头
技术领域
本实用新型涉及医疗器具,尤其涉及腹腔镜手术用的器具。
背景技术
目前医院外科采用的微创手术已很普遍,特别是腹腔镜手术对患者创伤小,痛苦少,很受欢迎。但由于使用的手术器具都是直式的,在一个切口里同时操作两种器具时容易产生“筷子效应”,即不容易实现交叉操作,操作空间受限,操作者不方便实术。例如使用腹腔镜针式(超声刀头)时就属于这种情况。
发明内容
本实用新型的目的是设计一种腹腔镜针式单曲超声刀头,通过设计的单曲弯状结构解决操作不方便的问题。
一种腹腔镜针式单曲超声刀头,它包括超声刀头本体,其特征在于,超声刀头的前端向下弯曲,弯曲端长度为3~8cm,弯曲弧度为120~150°。
本实用新型的优点是,使用时,由于折弯的作用,使钩部有3~8cm半径的活动范围,便于施术者操作。
附图说明
图1是本实用新型的示意图。
具体实施方式
如图1所示,本实用新型主要是将现有超声刀头的前端向下弯曲,弯曲端长度L=3~8cm,弯曲弧度α=120~150°。
