    • A curved bore hole drilling apparatus and method utilizing two poer driven drill shafts (21, 22) equipped with flexible shaft sections (23, 24) on the distal ends thereof with each flexible shaft section (23, 24) having a cutting tip (26). A semicircular channel shaped drill guide (153) loosely engages each flexible shaft end section (23, 24) and is caused to rotate through an approximately 90 DEG angle as the cutting tips (26, 28) are advanced. The drill guides (53, 54) are pivotally mounted for rotation in substantially the same plane and, when rotated through an approximate 90 DEG angle so as to meet, the cutting tips (26, 28) of the associated rotating flexible drill bits form a curved semicircular bore hole which may extend through 180 DEG . The flexible shaft sections (23, 24) and guides (53, 54) are then backed out of the bore and the bore may be used for attachment of a tie such as a wire or a suture which is passed through the bore.
    • 一种弯曲的钻孔装置和方法,其利用两个在其远端上配备有柔性轴部分(23,24)的钻头轴(21,22),每个柔性轴部分(23,24)具有切割尖端 )。 半圆形通道形钻子引导件(153)松动地接合每个柔性轴端部分(23,24),并且随着切割尖端(26,28)前进,使其旋转大约90°角。 钻子引导件(53,54)枢转地安装成在基本上相同的平面中旋转,并且当旋转大约90°的角度以相交时,相关联的旋转的柔性钻头的切割尖端(26,28)形成 弯曲的半圆孔可延伸180度。 柔性轴部分(23,24)和引导件(53,54)然后从孔中退出,并且孔可以用于连接诸如电线或穿过孔的缝线的连接件。
