Surgical ring e.g. annuloplasty ring, for biological organ e.g. stomach, of patient, has locking units comprising different external coloration so as to visually locate relative positioning defect of units with respect to locking position

摘要

The ring has an elongated main locking body (2) terminated towards two ends of the ring by locking units formed by a female unit and a male unit, respectively, which cooperate together to define a set point locking position. The locking units occupy a unique and prestabilized relative part in the set point locking position, where each locking unit has different external coloration so as to visually locate a relative positioning defect of the locking units with respect to the locking position and irrespective of vision angles. The female unit and male unit are made of plastic material.
