A medical polymer material in which a phosphate group having a C&#x2014;O&#x2014;P chemical bond including elemental C in a main chain of a structural formula is present on a surface of a polymer material substantially free of phosphate and hydroxy groups except for ends in the structural formula.

Medical polymer material having excellent bone-bonding property

A medical use honeycomb structure having a plurality of through-holes extending in one direction, wherein an outer peripheral section of the medical use honeycomb structure has a through-hole groove formed by incomplete side walls of the through-hole, and a through-hole inlet adjacent to the through-hole groove.

Medical use honeycomb structure

To provide a method for producing a calcium carbonate block for medical use which is useful as a bone substitute or a bone substitute raw material needed in medical care, which is a method for producing a calcium carbonate block that satisfies the following desired properties: 1) the calcium carbonate block has excellent mechanical strength; 2) the calcium carbonate block can be produced by a simplified production method; 3) the calcium carbonate block contains no impurity; and 4) the calcium carbonate block has high reactivity. A method for producing a calcium carbonate block, comprising a step of shaping a water-containing calcium hydroxide block and a carbonation step of immersing the calcium hydroxide block in a carbonate ion-containing aqueous solution.
