[Evaluation of Muscle Fatigue in Spinal Surgery Instruments Based on sEMG-JASA].

Author: Mao, Ningbo ; Wang, Li ; Cao, Gengyu ; Zhang, Yu ; Zhao, Yu ; Hou, Yuxiao

Based on the joint analysis of EMG spectrum and amplitude method (JASA), a study on muscle fatigue assessment of spinal surgical instruments based on surface EMG signals was carried out, and a comparative evaluation of the operating comfort before and after the optimization of spinal surgical instruments was completed. A total of 17 subjects were recruited to collect the surface EMG signals of their brachioradialis and biceps. Five surgical instruments before and after optimization were selected for data comparison, and the operating fatigue time proportion of each group of instruments under the same task was calculated based on the RMS and MF eigenvalues. The results showed that when completing the same operation task, the operation fatigue time of the surgical instruments before optimization was significantly higher than that after optimization (P<0.05); there was no significant difference in the fatigue status of brachioradialis and biceps when operating the same instrument (P>0.05). These results provide objective data and reference for the ergonomic design of surgical instruments and fatigue damage protection.

Biomechanical study of on different thread structures of new pedicle screws

Author: Fan Guoping ; Liu Zhenhai ; Huang Xiyi

Objective To compare the rotating torque and the extraction strength of the existing standard pedicle screws with three newly designed pedicle screws(the thread profile angle and the thread internal diameter taper are different)in the polyurethane material to study the biomech. properties of new pedicle screws and explore the biomech. properties of design elements of pedicle screw.Methods The standard pedicle screw and three newly designed pedicle screws were tested in a 40-grade polyurethane material by screwing in a torsion testing machine.At the same time, the standard pedicle screw and three newly designed pedicle screws were tested on the extraction performance of the20 grade polyurethane material on the universal testing machine.Both the rotating torque test and the extraction performance test were tested according to the Chinese pharmaceutical industry standard YY/T0119.2-2014 and the American Society for Testing and Materials(ASTM) standard ASTM F543.The polyurethane material adopted the standardized material of the American Society for Testing and Materials(ASTM) as the test block.Results The three new designs of pedicle screws were significantly higher than standard pedicle screws in both screwing torque and extraction performance.At the same time, the improvement of screwing torque was more obvious than the improvement of extraction performance.In addition, there were some differences among the three newly designed pedicle screws in the rotation torque and ex traction performance, but they were not obvious, especially in the anti-extraction performance.Conclusion Compared with standard pedicle screws, the newly designed pedicle screws have stronger biomech. fixation, but the difference among the new pedicle screws is not obvious.
