Needle insertion process of tissue engineering is one the most significant process in biomedical and tissue engineering. Tissue deformation will occur when needle try to punctures the tissue upper surface, it is an important issues of needle insertion process, which results the needle exact location into the tissue. In this study, a tissue deformation model of needle insertion process is discussed. A conical type of needle is used for needle penetration process. The techniques for calculating the radius and depth of the deformation are presented to estimate the volume of needle tissue deformation. The total needle force is also calculated, and the maximum displacement of the needle inside the tissue has been introduced.
