ABSTRACT
Objective To develop a cryogenic gripper for soft tissues used in tensile test for secure fixation of soft tissues without damages.Methods Based on the principle of coolant evaporator,we reconstructed copper pipes in novel architecture for fixing the soft tissues.Results This cryogenic gripper could firmly grip wet nylon thread of 3 mm in diameter and its holding force was(499.14?1.05)N and its temperature could be kept at(-20?1)℃.Conclusion The function of this gripper developed by coolant cryogenic technology is satisfactory and reliable,and its continuance is not concerned with time.
