钛材在医疗器械上的应用越来越广泛,早期主要用来制作一些缝合细小血管用的针、心电图电极材料以及眼科用器械.近年来已用作心脏拉钩和心脏堵头,这是心脏手术过程中使用的辅助医疗器械,它要求强度高、耐腐蚀、无毒性、易于清洗.心脏堵头一般根据堵头的直径大小分为6种型号:20～19mm、18～17mm、16～15mm、14～13mm、12～11mm、10～9mm.心脏拉钧分为大号、小号两种.大号杆粗φ12mm,小号杆粗φ10mm.大号钧宽有24mm、
Titanium is more and more widely used in medical devices and mainly used to make needles, electrocardiogram electrode materials and ophthalmic instruments used for sutured small blood vessels in the early stage. In recent years, it has been used as heart pull hooks and heart plugs, which are heart surgery Auxiliary medical devices used in the process, it requires high strength, corrosion resistance, non-toxic, easy to clean.Cear plug according to the size of the plug is generally divided into 6 types: 20 ~ 19mm, 18 ~ 17mm, 16 ~ 15mm, 14 ~ 13mm, 12 ~ 11mm, 10 ~ 9mm. Heart pull Jun is divided into large and small two. Large rod thick φ12mm, small rod thick φ10mm. Large Jun wide 24mm,
