A surgical anchor is provided with one or more anchor holes distributed around the head of the anchor. Each anchor hole is inclined to allow attachment of one or more sutures to the anchor either before, during or after the anchor is seated in a bone. The upper and lower apertures of each anchor hole are chamfered, and the chamfered areas from the anchor hole to the outside edge shall be polished or somehow smoothed to remove sharp edges and rough areas which may cause friction and abrasion to soft tissue or suture material. The lower surface of the anchor head may be angled to further simplify the task of feeding a surgical needle through the anchor hole after the anchor is seated into bone.

La présente invention concerne une vis de retenue chirurgicale comprenant un ou plusieurs trous de fixation distribués autour de la tête de la vis. Chaque trou de fixation est incliné de manière que l'on peut attacher un ou plusieurs fils de suture à la vis de retenue avant, pendant ou après que la vis a été installée dans l'os. Les ouvertures supérieure et inférieure de chaque trou de fixation sont chanfreinées et les zones chanfreinées, qui vont du trou de fixation jusqu'au bord externe, sont polies ou adoucies d'une manière ou d'une autre afin d'éliminer les bords tranchants et les zones rugueuses qui pourraient entraîner un frottement ou une abrasion des tissus mous ou du matériau de suture. La surface inférieure de la tête de la vis de retenue peut être biseautée afin de simplifier encore l'introduction d'une aiguille chirurgicale à travers le trou de fixation après que la vis de retenue a été installée dans l'os.
