Abstract: The present invention provides a replaceable micro-surgical instrument which comprises a pull structure and a hollow tube attached to a grip. The hollow tube has a sleeve at one end with a U-type elastic element sliding in. The U-type elastic element includes a spring tension section and two opposite extending arms and the outer edge of each arm is against the inner wall of the sleeve. Two arms could move according to the pull structure to selectively extend out of the sleeve to be opened or pull back into the sleeve to be clip together. Particularly, there is a replaceable micro-surgical element set in the front-end of each arm, so when the micro-surgical element becomes blunt or broken, the doctor could only replace the micro-surgical element without replace a whole new instrument in order to reduce instrument cost, increase replacement rate, and maintain the quality of medical surgery.

Abstract translation: 本发明提供了一种可替换的微型手术器械，其包括拉结构和附接到手柄的中空管。 中空管的一端具有一个U型弹性元件滑入的套筒.U型弹性元件包括弹簧张力部分和两个相对的延伸臂，每个臂的外边缘抵靠套筒的内壁 。 两个臂可以根据拉结构移动以选择性地延伸出套筒以打开或拉回到套筒中以夹在一起。 特别是，在每个臂的前端设置有可更换的微手术元件，因此当微手术元件变钝或破裂时，医生只能替换微手术元件而不是按照新的装置替换全新的器械 降低仪器成本，提高替代率，保持医疗手术质量。
