摘要

研究设计一项生物力学研究:我们旨在评估椎板切除术中使用超声骨刀时的温度波动,并确定机器人辅助椎板切除术中最合适的切割方法,以降低热相关损伤的风险:研究利用机器人系统进行椎板切除术,使用超声骨刀切割人工聚氨酯骨和动物脊柱骨。研究重点是通过三种不同的切割技术,比较和分析四种人工骨骼内表面的最高温度:速度分别为 0.5 毫米/秒和 1 毫米/秒的垂直恒定切割,以及机器人辅助的垂直往复切割。在得出初步结果后,选择了两种最佳垂直切割方法进行后续试验,评估各种超声波截骨器模式对 10 块分离的猪脊柱骨的有效性和温度影响:结果:在切割聚氨酯骨骼时,往复式切割与 0.5 毫米/秒和 1 毫米/秒的恒速切割相比,最高温度最低。在动物骨骼试验中,直接切割的平均最高温度为 43.25°C,平均切割时间为 688.3 秒,而往复切割的平均最高温度为 34.20°C,平均切割时间为 713.0 秒:结论:机器人辅助超声波截骨器采用的往复式切割策略可有效减少发热,并保持较高的切割效率。

Efficiency and Heat Production of Ultrasonic Osteotome Strategy in Robot-Assisted Laminectomy.

Study design: A biomechanical study.

Objective: We aimed to assess temperature fluctuations when applying the ultrasonic osteotome during laminectomy and identify the most appropriate cutting method for robot-assisted laminectomy to mitigate the risk of heat-related injuries.

Methods: Utilizing a robotic system for laminectomy, the study implemented the ultrasonic bone scalpel to cut both artificial polyurethane bones and animal spinal bones. The research focused on comparing and analyzing the maximum temperature of the inner surface of four types of artificial bones through three different cutting techniques: vertical constant cutting at speeds of .5 mm/s and 1 mm/s, as well as robot-assisted vertical reciprocating cutting. After the initial results, two optimal vertical cutting approaches were selected for subsequent trials, evaluating the effectiveness and temperature impact of various ultrasonic osteotome modes on 10 isolated spinal bones from pigs.

Results: When cutting polyurethane bones, reciprocating cutting demonstrated the lowest maximum temperature in contrast to constant speed cutting at .5 mm/s and 1 mm/s. In the animal bone trial, direct cutting registered an average maximum temperature of 43.25°C with an average cutting duration of 688.3 s, while reciprocating cutting recorded an average maximum temperature of 34.20°C with an average cutting time of 713.0 s.

Conclusions: The reciprocating cutting strategy utilized in robot-assisted ultrasonic osteotome is effective in reducing heat generation and maintaining high cutting efficiency.
