Tissue engineering aims to produce a functional tissue replacement to repair defects. Tissue reconstruction is an essential step toward the clinical application of engineered tissues. Significant progress has recently been achieved in this field. In our laboratory, we focus on construction of cartilage, tendon and bone. The purpose of this review was to summarize the advances in the engineering of these three tissues, particularly focusing on tissue regeneration and defect repair in our laboratory. In cartilage engineering, articular cartilage was reconstructed and defects were repaired in animal models. More sophisticated tissues, such as cartilage in the ear and trachea, were reconstructed both in vitro and in vivo with specific shapes and sizes. Engineered tendon was generated in vitro and in vivo in many animal models with tenocytes or dermal fibroblasts in combination with appropriate mechanical loading. Cranial and limb bone defects were also successfully regenerated and repaired in large animals. Based on sophisticated animal studies, several clinical trials of engineered bone have been launched with promising preliminary results, displaying the high potential for clinical application.

This study aims to optimize the geometrical parameters of an under-actuated mechanical finger by conducting a theoretical analysis of these parameters. The finger is actuated by a flexion tendon and an extension tendon. The considered parameters are the tendon guide positions with respect to the hinges. By applying such an optimization, the correct kinematical and dynamical behavior of the closing cycle of the finger can be obtained. The results of this study are useful for avoiding the snap-through and the single joint hyperflexion, which are the two breakdowns most frequently observed during experimentation on prototypes. Diagrams are established to identify the optimum values for the tendon guides position of a finger with specified dimensions. The findings of this study can serve as guide for future finger design.

本文介绍了基于约束型蛇形拉线机构(CTSM)的新型柔性机器人系统。与达芬奇外科手术机器人和传统柔性机器人相比,基于CTSM的机器人具有更大的工作空间,更高的灵巧度以及刚度可控的优点。该机器人采用Novint Falcon触觉设备进行远程操控, 包括两种操作模式——直接映射模式和增量模式。在每一种模式下,该机器人都可以采用“最大刚度”方案或“最小运动”方案来操控。CTSM的以上优点在仿真模拟和实验中均得以验证。
