    摘要: A needle sheath includes a tubular shaft having a chamfered edge at a distal end thereof. A stop flange is secured to a proximal end of the tubular shaft. A needle relief slot is formed in a bottom side of the tubular shaft. The needle relief slot has a length that extends along an axis that is parallel to the longitudinal axis of the tubular shaft. A needle point slot formed in a top side of the tubular shaft. The needle point slot has a length that extends along an axis that is perpendicular to both the longitudinal axis of the tubular shaft and the needle relief slot axis. A suture needle is disposed within the tubular shaft of the needle sheath. The suture needle has a curved body that passes through the needle relief slot and a needle point captured within the needle point slot.
