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.

The present invention relates to an improvement in the construction of water ride surfaces and comprises at least one layer of soft permeable material built into the padded substrate of a structurally supported ride surface. The permeable material connects to a drainage system and is preferably sandwiched between a slick skin upper waterproof membrane, and a supporting substrate beneath it. The advantage to this improvement is when water leaks through the waterproof membrane, the permeable material prevents water from building up inside the padded substrate, and allows the water to be drained out, rather than blistering and bubbling up under the waterproof membrane, thereby helping to preserve the integrity and longevity of the ride surface.
