Abstract

The invention provides a device and method for undeformed transferring of a biological soft tissue. An ejection tray (105), a dial (106), a worm (107), a pivotal bearing (110), a turbine (111) and the like are packaged in a rotating table assembly (1); rotation of the worm (107) is controlled through a stepper motor (4) to drive the turbine (111) to rotate; the turbine (111) is connected with a disk table (104) through the pivotal bearing (110) to control rotation of the disk table (104), so that a scanner conveniently scans a biological soft tissue sample on the ejection tray; and particularly, a handheld device is provided with a single-axis mechanical gyroscope (304), and the biological soft tissue and the ejection tray (105) can be always kept in a horizontal state by using the single-axis mechanical gyroscope (304) while the biological soft tissue sample has no morphologic change in the transferring process, so that the consistency of the biological soft tissue sample with a geometrical model is ensured and the accuracy of experiment data is ensured.

Description

technical field [0001] The present invention mainly relates to a device and method for biological soft tissue transfer, in particular to a device and method capable of not changing the original shape of biological soft tissue samples during the transfer process. Background technique [0002] In the field of biomedicine, in order to accurately obtain the mechanical properties of biological soft tissue, it is usually necessary to carry out three-dimensional geometric modeling of biological soft tissue samples, and construct a finite element model through the geometric model for simulation, and combine the experimental reverse technology to obtain the mechanical properties of biological soft tissue . [0003] The difference between the geometric model of biological soft tissue samples obtained by scanning for finite element simulation and the geometric shape of samples in mechanical experiments determines the accuracy of the material parameters of biological soft tissue samples...
