Abstract: A surgical instrument for fastening together opposing portions of a body organ. The instrument comprises a first support for supporting the first opposing portion of the body organ, a second support opposing the first support, for supporting the second opposing portion of the body organ, and a displacement-preventing member connected to the first or second support for preventing the supports from displacing relative to each other. The member comprises a pin protruding from one of the supports and a hole formed in the other of the supports. The pin is made of thermoplastic resin. When heated, the pin is softened and deformed, whereby the first and second supports are secured to each other, fastening together the opposing portions of the body organ.

Abstract: In a coding system, when any of the prediction results of pixel value prediction sections 20 and 21 matches an object pixel, a coding section 50 codes an identifier of the pixel value prediction section whose prediction result matches the object pixel. When none of the results match the object pixel, the coding section 50 codes a prediction error of a prediction error calculation section 30. A decoding system decodes code to an identifier or prediction error and outputs pixel data from the corresponding pixel value prediction section based on the identifier or takes out pixel data from a prediction error addition section 31 based on the predication error.
