Description

一种可换电极吸烟刀
技术领域
本发明涉及一种外科手术用的电刀。
背景技术
外科手术中在使用手术电刀进行电切割时， 会产生大量的烟雾， 阻碍了医 生在手术中的视野， 吸烟刀因此而诞生。 现有技术中， 吸烟刀能吸取烟雾、 组 织碎屑、 血迹等废弃物， 同时也能对创面进行冲洗， 但是该类手术刀结构复杂， 且刀头单一、 不可更换， 造成手术中需更换不同长度、 类型的手术刀， 带来了 手术不便。
发明内容
为了克服吸烟电刀的刀头不可更换的缺点， 提供一种结构简单， 使用方便， 吸烟效果较好， 且可更换不同长短、 形状的带电极吸引管刀头的吸烟刀。
本发明所述的可换电极吸烟刀， 包括后端带吸引装置的电刀手柄、 用于固 定吸引管的底座、 前端带电极的吸引管， 所述的底座设置在所述的电刀手柄的 前部， 其特征在于： 所述的吸引管的后端与所述的底座以可脱卸的方式连接， 并传导电流。
进一步， 所述的吸引管的后端形成设有内螺纹的第一套筒， 所述的底座的 前端设有与所述的内螺纹配合的外螺纹。
或者， 所述的底座的前端形成带锥形的第二套筒， 所述的吸引管的后端形 成与所述的第二套筒配合的带锥度的第一插入头。
或者， 所述的底座的前端形成第三套筒， 所述的吸引管的后端形成可插入 所述的第三套筒的第二插入头， 所述的第二插入头与所述的第三套筒之间以插 销连接。
本发明的带电极的吸引管可根据手术需要方便地更换， 有不同长短和不同形 状， 吸引管形状有球形， 三角形， 环形等， 可用于不同手术。 可符合不同的使 用习惯， 免除死角， 方便使用， 一刀多用。
本发明的优点是： 结构简单， 使用方便， 吸烟效果较好， 且可更换不同长短、 形状的带电极吸引管刀头。
附图说明
图 1是本发明的整体示意图
图 2是吸引管与底座以螺纹方式连接的示意图
图 3是图 2的局部放大图
图 4是吸引管与底座以锥形插接方式连接的示意图
图 5是图 4的局部放大图
具体实施方式
下面结合附图进一步说明本发明
实施例 1

可换电极吸烟刀， 包括后端带吸引装置的电刀手柄 4、用于固定吸引管的底 座 3、前端带电极 1的吸引管 2，所述的底座 3设置在所述的电刀手柄 4的前部， 所述的吸引管 2的后端与所述的底座 3以可脱卸的方式连接， 并传导电流。
所述的吸引管 2的后端形成设有内螺纹的第一套筒 6，所述的底座 3的前端 设有与所述的内螺纹配合的外螺纹 5。
所述的底座 3可以相对电刀手柄 4外露， 也可以内藏在电刀手柄 4内。 所述的电刀手柄 4上设有电切按钮 7和电凝按钮 8. 通过拧紧或拧松所述的螺纹， 可以方便地更换带电极吸引管刀头。
实施例 2
参照附图 4、 5：
本实施例与实施例 1的区别在于吸引管 2与底座 3之间的连接方式不同： 底座 3的前端形成带锥形的第二套筒 10， 所述的吸引管 2的后端形成与所述的 第二套筒 10配合的带锥度的第一插入头 9。
通过第二套筒 10与第一插入头 9之间的锥度配合， 用抵紧或退出第一插入 头 9的方式， 就可以方便地更换带电极吸引管刀头。
实施例 3
本实施例与实施例 1的区别在于吸引管 2与底座 3之间的连接方式不同： 所述的底座 3的前端形成第三套筒， 所述的吸引管 2的后端形成可插入所述的 第三套筒的第二插入头， 所述的第二插入头与所述的第三套筒之间以插销连接。
通过插入或拔出插销， 可以方便地更换带电极吸引管刀头。 本发明的保护范围不应当被视为仅限于实施例所陈述的具体形式， 本发明的 保护范围也及于本领域技术人员根据本发明构思所能够想到的等同技术手段。
