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 first substrate includes lenses for focusing light on an information storage medium, a second substrate includes detectors and disposed on the surface thereof, and a layer, which is disposed between the first and second substrates, includes prisms and mirrors. The layer also includes cavities in which light sources are disposed. The individual substrates are formed in the form of wafers with the lenses, mirrors, prisms, light sources, and photodetectors disposed thereon.
