Objective:To investigate the feasibility and safety of implementing a domestic vehicle-mounted remote mobile robotic surgical system in thyroid surgery applications, integrated with 5G communication technology.Methods:Using the main system located on the vehicle-mounted mobile robot operating platform of the 960th Hospital of PLA Joint Logistics Support Force and the slave system of Weifang Traditional Chinese Hospital, the remote radical thyroidectomy 5G communication technology, and analyze the clinical and information transmission data of two female patients who underwent remote mobile robot thyroid cancer surgery on October 21, 2024 at Weifang Traditional Chinese Medicine Hospital.Results:The remote radical thyroidectomy was conducted by the robosurgeons utilizing a vehicle-mounted mobile robotic surgical system, and the procedure was successfully completed without necessitating intermediate open surgery. The operation durations for patient 1 and patient 2 were 135 minutes and 108 minutes, respectively, with 7 and 13 lymph nodes dissected, respectively. The average delay in surgical data transmission was recorded at 61.9 milliseconds, with no instances of signal interruption or frame loss. The procedure proceeded smoothly, without any jamming, and the audio and video transmissions were consistently clear. Follow up for 21 days after surgery showed no complications such as hoarseness, skin damage, or lymphatic fistula.Conclusion:The implementation of a vehicle-mounted remote mobile robotic surgery system for thyroid surgery has demonstrated safety and feasibility. Furthermore, the utilization of the 5G network offers rapid data transmission and minimal latency, closely approximating the therapeutic efficacy of traditional robotic thyroidectomy.

Objective Assess and determine inactivation effect of heat,.ultraviolet (UV) light and three disinfectants against human infected H9N2 avian influenza virus in laboratory.Methods Suspension containing with 1010.67 TCID50/ml viral was exposed to 50 ℃,56 ℃,60 ℃,65 ℃ for 10 to 60 minutes and UV every 10 interval minutes from 10 to 80 minutes.The residual viruses after physical treatment were determined through half of tissue culture infective dose (TCID50) with MDCK cells and calculated by Reed-Muench method.Suspension with 1010.37EID50/ml quantitative virus was applied to equal volume of 10％ 84 sanitizer,75％ ethanol,1％ Virkon solution and incubated for 1 minute to 15 minutes respectively.The residual viral activity would be evaluated by inoculating in SPF chicken embryo.When the virus titer dropped by 4 lgTCID50/ml or virus in chicken embryo culture was observed to be negative,the physical and chemical treatment was considered effective.Results Human infected H9N2 avian influenza virus titer decreased by 4.02 lgTCID50 at 56 ℃ for 15 minutes,and after 30 minutes at 56 ℃ or 10 minutes at 60 ℃/65 ℃,the post-viral titer would decline below the detection level.20 minutes of UV irradiation would lead to a 5.67 log reduction,and after 70 minutes lighted,the virus titer fell below the detection level.Virus proliferation was not detected after 3 minutes of disinfection with 10％ 84 sanitizer,75％ ethanol and 1％ Virkon.Conclusions We should note that it is necessary to meet the specific condition to effectively inactivate the human infected H9N2 avian influenza virus.Our study provides an experimental basis for the biosafety operation of human infected H9N2 avian influenza virus.
