摘要

目的研发一种用于生物力学测试的软组织夹头

解决传统方法不可避免损伤材料导致测量结果不精确的难题。方法应用成熟的制冷剂蒸发制冷原理对金属铜管蒸发器进行结构创新，制作一种具有冷冻夹持功能的软组织夹头

并对其技术性能进行初步测试。结果该冷冻夹头能够牢固夹持直径3 mm的尼龙丝线，最大夹持力(499.14±1.05)N，并且其温度可以保持在(－20±1)℃左右。结论这种运用制冷剂制冷原理研制的软组织冷冻夹头的功能可行有效，且冷冻效能维持不受时间限制。

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.
