Abstract

本实用新型提供一种骨孔安全钻头,其一端设有 夹持柄1、另一端设有麻花钻头4,其特征在于:位于 夹持柄1和麻花钻头4之间设有螺纹3,螺纹3上设 有螺母2,具有结构合理、操作简便、安全可靠性好、 减少对患者对侧组织不必要的剥离,而且还可以替代 骨孔测深尺,使骨孔钻孔和测量深度一次完成等优 点。

Description

本实用新型涉及一种医疗器械,特别是关于一种骨科用的骨孔安全钻头。
现有的骨孔钻头与工业用钻头相同,使用时在钻到对侧骨皮质后,因要防止对侧血管、神经损伤,经常要用器械剥离对侧组织来折挡钻头,不慎将对侧血管、神经损伤的现象时有发生,而且工作效率低、操作复杂。
本实用新型的目的是提供一种能防止损伤对侧血管和神经的骨孔安全钻头。
本实用新型的技术解决方案是:一种骨孔安全钻头,其一端设有夹持柄1、另一端设有麻花钻头4,其特征在于:位于夹持柄1和麻花钻头4之间设有螺纹3,螺纹3上设有螺母2。
本实用新型同现有技术相比具有:结构合理、操作简便、安全可靠性好、减少对患者对侧组织不必要的剥离,而且还可以替代骨孔测深尺,使骨孔钻孔和测量深度一次完成等优点。
附图1为本实用新型的结构示意图。
整个钻头采用锋钢制成,钻头的一端制成夹持柄1、另一端制成麻花钻头4,位于夹持柄1和麻花钻头4之间的一段制成螺纹3,螺纹3上设有可调节的螺母2,螺纹3和螺母2之间为紧密配合。
