Purpose

In present research work, the effects of rotational speed, feed rate and vibration amplitude have been investigated during novel method of ultrasonic-assisted bone grinding. During dissection of tumors, firstly a bone flap is removed near the target region to create passage for grinding burr. During abrasion, heat is produced, which sometimes increases the temperature to unsafe levels. So, efforts have been made to limit the temperature below the threshold levels of osteonecrosis during bone grinding.

Design/methodology/approach

The temperature produced during osteotomy has been measured using infrared thermography camera during the implementation of L18 Taguchi orthogonal array design. Subsequently, main effect plots and contour plots have been presented to analyze and visualize the effect of grinding parameters on temperature rise during bone grinding. Furthermore, the process parameters have been optimized for optimum results for response characteristics using Taguchi SN ratio-based optimization methodology. For multiobjective optimization, the process parameters are further optimized using grey relational analysis.

Findings

It is revealed that all three process parameters substantially affect the response characteristics. The proposed optimization methodology is successfully applied on the experimental findings and the optimum results for change in temperature are found to be rotational speed = 3,000 rpm, feed rate = 20 mm/min, amplitude = 10 µm and for standard deviation are 5,000 rpm, 60 mm/min, 10 µm.

Research limitations/implications

The present research findings cannot be generalized, and researchers are encouraged to further investigate the proposed rotary ultrasonic-assisted bone grinding at higher rotational speed up to 60k rpm on the skull bone.

Originality/value

The research on osteotomy is still at its initial phase, and continuous research is carried out for making patients’ life comfortable. In this direction, the authors have proposed a novel osteotomy method to limit the temperature below the threshold limit of osteonecrosis. The outcomes of the present study will be beneficial for the neurosurgeons working in this field.

使用Grey-Taguchi优化方法进行旋转超声神经外科骨磨的初步研究

目的

在当前的研究工作中，在新型超声辅助骨磨削方法中研究了转速，进给速度和振动幅度的影响。在解剖肿瘤期间，首先在目标区域附近去除骨瓣以形成磨削毛刺的通道。在磨损过程中会产生热量，有时会使温度升高到不安全的水平。因此，已经努力将温度限制在骨磨削期间的骨坏死阈值水平以下。

设计/方法/方法

在实施L18 Taguchi正交阵列设计期间，已使用红外热像仪测量了截骨过程中产生的温度。随后，提出了主要效果图和轮廓图，以分析和可视化磨削参数对骨骼磨削过程中温度升高的影响。此外，使用基于Taguchi SN比率的优化方法，针对响应特性的最佳结果对过程参数进行了优化。对于多目标优化，使用灰色关联分析进一步优化过程参数。

发现

揭示了所有三个过程参数基本上影响响应特性。所建议的优化方法已成功应用于实验结果，发现温度变化的最佳结果是转速= 3,000 rpm，进给速度= 20 mm / min，振幅= 10 µm，标准偏差为5,000 rpm，60毫米/分钟，10微米。

研究局限/意义

目前的研究结果不能一概而论，鼓励研究人员进一步研究拟议的旋转超声辅助骨磨削，以更高的转速在头骨上进行高达60k rpm的旋转。

创意/价值

截骨术的研究仍处于起步阶段，并不断进行研究以使患者生活舒适。在这个方向上，作者提出了一种新颖的截骨术方法，以将温度限制在骨坏死阈值以下。本研究的结果对于在该领域工作的神经外科医生将是有益的。
