Abstract

本实用新型属于一种医用颅锥,包括:T型柄1,锥芯2,锥头3,固定螺母4A、4B,锥头3与T型柄1通过螺母4A暂时固定。本实用新型颅锥具有暂时固定头皮、颅骨、硬膜锥孔、止血、省力、穿刺顺利特点。

Description

可脱性颅锥
本实用新型属于一种医用锥颅器械。
现行的用于对脑外科病人急诊锥颅、脑室穿刺、脑室外引流的颅锥,其结构如图1所示,锥体7,锥柄6,锥体下可固定旋扭8。操作时,根据颅骨厚度固定旋扭8,锥通头皮、颅骨、硬脑膜后再拔出颅锥,顺上述锥孔行脑室穿刺。这种颅锥虽然有结构简单的优点,但存在下列缺陷:拔除颅锥后头皮易滑动使皮肤锥孔与颅骨、硬膜锥孔移位,脑室穿刺针难于找到准确位置;拔除颅锥后头皮及颅骨易出血影响操作;用力较大时固定旋扭易滑动致锥颅过深。
本实用新型的目的是:提供一种新型颅锥,该颅锥具有操作方便,暂时固定头皮、颅骨、硬膜的锥孔,挤压锥孔止血,便于顺利脑室穿刺。图2为本实用新型的结构示意图。本实用新型采取以下方式实现:该颅锥由带扳口5的T型柄1,锥芯2,锥头3,控制螺母4A、4B。使用时将锥芯2插入T型柄1内,锥头3插入T型柄1末端接口处,旋转螺母4A于接口上下固定锥头3,根据颅骨厚度,旋螺母4B于预定深度。锥通颅骨后,逆时针旋转螺母4A离开锥头3于T型柄1末端连接处,拔除T型柄1及锥芯2,于锥头3内孔行脑室穿刺,穿刺成功后,用T型柄1上的扳口5或T型柄1末端插口从侧面扳锥头3上方,逆时针旋转,即可取出锥头3。锥头3末端为螺旋状,较原来颅锥骨省力且易控制深度。

Claims (1)

  1. 一种医用颅锥,包括T型柄1,锥芯2,锥头3,螺母4A、4B,扳口5。
