A surgical instrument is disclosed. The instrument includes a handle configured to move between an open position and a closed position; at least one clamping structure coupled to the handle. The at least one clamping structure includes a first set of pushing members operatively coupled to the handle. The movement of the handle from open position to the closed position facilitates the movement of pushing members into longitudinal direction. The at least one clamping structure includes a set of constrictors coupled to the set of the pushing members such that movement of the set of the pushing members enables movement of the set of constrictors from a designed position in which the set of constrictors are positioned away from each other and to a contracted position in which the set of constrictors are positioned closed to each other.
