The invention relates to a binding mechanism of a surgical binding apparatus, which is placed at the head of the surgical binding apparatus and includes a nail pin, a nail pushing plate and a nail block. The nail pushing plate and the nail pin are installed inside the binding apparatus body. The positions of the nail block and the nail pushing plate are opposite. The invention is characterized in that the working faces of nail pin, the nail pushing plate and the nail block are not at the same plane and at least present a step-type fall distributed structure. When the structure is adopted to form an anastomoses opening, the distance between two lines of nails is enlarged; the elasticity of the anastomoses opening which is formed in the operation is increased and is more close to the physiological characteristic of the tissue, which is in favor of the prompt recovery of the tissue. When the nail block is set out from an anastomoses ring or a content object is put through the anastomoses ring after binding, the elasticity of the anastomoses ring becomes larger to allow the nail block or the content object pass through and reduce the probability of damaging the anastomoses ring.

A method and system for multiplexing a network of parallel fiber Bragg grating (FBG) sensor-fibers to a single acquisition channel of a closed Michelson interferometer system via a fiber splitter by distinguishing each branch of fiber sensors in the spatial domain. On each branch of the splitter, the fibers have a specific pre-determined length, effectively separating each branch of fiber sensors spatially. In the spatial domain the fiber branches are seen as part of one acquisition channel on the interrogation system. However, the FBG-reference arm beat frequency information for each fiber is retained.

The multiple branches are seen as one fiber having three segments where the segments can be resolved. This greatly simplifies optical, electronic and computational complexity, and is especially suited for use in multiplexed or branched OFS networks for SHM of large and / or distributed structures which need a lot of measurement points.
