Abstract

一种手术用电凝钩，依次包括一体成型的接口部（3）、体部（1）和钩部（2），体部（1）外覆有绝缘层（11）；钩部（2）与体部（1）成110°至140°的夹角。该电凝钩具有可塑性，便于术中适应不同角度，易于实现精细分离操作。

Description

手术用电凝钩
技术领域
本实用新型涉及医疗器械， 具体涉及手术用电凝钩。
背景技术
电凝钩主要用于微创手术中，在手术中起到分离切割人体组织以 及电凝止血的功能。 现在的电凝钩具有如下不足： 1、 设计上均为角 度固定， 一般为 90度或者 0度， 不能适应术中不同角度和周围存在 复杂结构时的需要； 当年设计者为避免电凝钩伸入体腔出现误伤所设 计的 90度或者 0度钝头形状在现有的技术下已属不必要。 1、 为了适 应不同的角度， 有的设计釆用刀身釆用较为具有弹性的材料， 但在术 中容易出现难以控制弹力的现象， 可能导致危险。 3、 现有的电凝钩 的尖端往往较为圓钝粗大，难以精细分离诸如血管鞘膜等需要精细解 剖的组织。
实用新型内容
针对上述现有技术不足，本实用新型要解决的技术问题是提供一 种电凝钩， 能适应手术时的复杂结构使用、 适应不同角度、 容易精细 分离组织。
为解决上述技术问题， 本实用新型釆用的技术方案为， 手术用电 凝钩，依次包括一体成型的接口部、体部和钩部，体部外覆有绝缘层； 钩部与体部成 11 0° 至 140° 的夹角。 这样的结构能满足实际手术中 的使用需要， 具有极大的灵活性。
进一步的技术方案为 ,体部的前端部横截面直径自后向前逐渐减 小， 所述前端部是指靠近钩部的一端。 这样的结构可最大限度减少对 操作区视野的阻碍。
优选地，体部与钩部接合处的横截面直径为为 0. 6毫米至 1. 0毫 米； 钩部的横截面直径与接合处匹配。 这样的结构使钩部钩尖精细而 不过尖。
更优地， 所述体部为塑性不锈钢体部， 所述钩部为塑性不锈钢钩 部。 这样的结构更容易适应手术操作的不同角度， 塑性材质可以避免 弹性不能控制的情况， 也可以调整以绕过不能直线到达的组织。
更优地， 所述钩部外涂设有不粘涂层。 这样的结构可以减少术中 钩部粘连凝固物。
本实用新型的手术用电凝钩钩尖端精细而又不过尖，且具有可塑 性，便于术中调整角度，能灵活应对手术的使用需要，适应不同角度， 并易于实现精细分离操作。
附图说明
图 1是本实用新型手术用电凝钩的结构示意图。
图 2是图 1的 A区域放大图。
其中， 1、 体部； 1 1、 绝缘层； 12、 接合处； 2、 钩部； 3、 接口 部。
具体实施方式
如图 1和图 2所示，本实用新型的手术用电凝钩依次包括一体成 型的接口部 3、 体部 1和钩部 2 , 体部 1外覆有绝缘层 11 ; 钩部 2与 体部 1的夹角 B成 110° 至 140° , 本实施例中为 115° 。 体部 1的 前端部横截面直径自后向前逐渐减小，所述前端部是指靠近钩部 2的 一端。 体部 1与钩部 2接合处 12的横截面直径为为 0. 6毫米至 1. 0 毫米， 本实施例中为 0. 8毫米； 钩部 2的横截面直径与接合处 12匹 配。 所述体部 1为塑性不锈钢体部， 具有塑形能力， 所述钩部 2为塑 性不锈钢钩部。 钩部 2外还可以涂设有不粘涂层（图未示出）， 当然 根据实际使用需要也可以不涂上不粘涂层。
对本领域的技术人员来说， 可根据以上描述的技术方案以及构 思， 做出其它各种相应的改变以及形变， 而所有的这些改变以及形变 都应该属于本实用新型权利要求的保护范围之内。
