Abstract

Background

The efficacy of laminectomy procedures is contingent on the method of resection. The objective of this study was to investigate the impact of different methods of resection on the surgical safety of automated laminectomy robots, an area that remains uncharted.

Methods

Lamina resection surgeries using both drilling and layer-by-layer methods, are performed on ovine spinal samples. An analysis of the force and lateral deviation at the end of the robotic arm is conducted.

Results

For the drilling and layer-by-layer lamina resection methods, the average peak force for the drilling method is 1.21 N, and deviations are within 1 mm. For the layer-by-layer resection method, the peak force reaches 2.39 N, and deviations are within 1.6 mm.

Conclusion

During the drilling resection, the ultrasonic osteotome experiences less force and minimal lateral deviation. This method demonstrates higher precision and safety in laminar resection surgeries. The drilling method should be the primary choice for robot manufacturers.

椎板切除术方式对自动椎板切除术机器人手术安全性的影响。

背景：椎板切除术的疗效取决于手术切除的方法。本研究的目的是研究不同的切除方法对自动椎板切除术机器人手术安全性的影响，这是一个未知的领域。方法：采用钻孔法和逐层法对羊脊髓标本进行椎板切除手术。对机械臂末端受力和侧向偏差进行了分析。结果：钻孔法和逐层椎板切除法，钻孔法的平均峰值力为1.21 N，偏差在1 mm以内。逐层切除时，峰值力可达2.39 N，偏移量在1.6 mm以内。结论：钻孔切除时，超声截骨术受力较小，侧向偏移最小。该方法在椎板切除术中具有较高的精确度和安全性。钻孔法应该是机器人制造商的首要选择。

期刊介绍： The International Journal of Medical Robotics and Computer Assisted Surgery provides a cross-disciplinary platform for presenting the latest developments in robotics and computer assisted technologies for medical applications. The journal publishes cutting-edge papers and expert reviews, complemented by commentaries, correspondence and conference highlights that stimulate discussion and exchange of ideas. Areas of interest include robotic surgery aids and systems, operative planning tools, medical imaging and visualisation, simulation and navigation, virtual reality, intuitive command and control systems, haptics and sensor technologies. In addition to research and surgical planning studies, the journal welcomes papers detailing clinical trials and applications of computer-assisted workflows and robotic systems in neurosurgery, urology, paediatric, orthopaedic, craniofacial, cardiovascular, thoraco-abdominal, musculoskeletal and visceral surgery. Articles providing critical analysis of clinical trials, assessment of the benefits and risks of the application of these technologies, commenting on ease of use, or addressing surgical education and training issues are also encouraged. The journal aims to foster a community that encompasses medical practitioners, researchers, and engineers and computer scientists developing robotic systems and computational tools in academic and commercial environments, with the intention of promoting and developing these exciting areas of medical technology.
