ABSTRACT
Objective The purpose of this study is to acquire and analyze the force signal of clinical liposuction and design a fat-mimicking phantom for liposuction training. Methods The force signal data of five clinical liposuction cases were processed, based on which a human subcutaneous fat mimicking phantom was made. We utilized a dynamic time warping (DTW) algorithm to test the similarity between the mimicking phantom and subcutaneous fat. Results The average resistance of the liposuction was 7.36 N, and the optimal gelatin concentration of the phantom was 11.47%. There was no significant difference between the variation tendency of the resistance of simulated liposuction and clinical liposuction (P > 0.05). Conclusion The mimicking phantom has suction force feedback similar to that of human subcutaneous fat.
