随机方法(请说明由何人用什么方法产生随机序列):

受试者按1:1比例随机分为治疗组和对照组。每名受试者应严格按照入组时间顺序获得一个治疗随机号,以决定受试者进入治疗组或对照组。

Randomization Procedure (please state who generates the random number sequence and by what method):

Subjects will be randomly assigned to the treatment group or the control group in a 1:1 ratio. Each subject should receive a treatment randomization number strictly according to the order of enrollment, which will determine whether the subject enters the treatment group or the control group.

盲法:

本研究除对干预操作者不进行设盲外,对受试者、术者、结局评估者、数据分析者均设盲,试验中为了保证盲法的实施,研究单位配备专人进行仪器分配,参与受试者的选择,疗效和安全性评估,数据分析的相关人员不能接触仪器分配及使用过程。 全部试验结束进行统计分析时方可揭盲。在紧急情况下,如发生严重不良事件又不能判断与治疗仪器是否有关,急需知道导致不良事件原因决定抢救方案时,需要提前破盲。破盲后要及时记录提前破盲的时间、原因和执行破盲人员,同时尽快通知监查员。一旦提前破盲,该受试者不能继续参加研究,且其试验数据不能用于后续分析,但是仍要列入安全分析数据集。对受试者还应做好及时的治疗和保护。

Blinding:

In this study, blinding was implemented for the subjects, surgeons, outcome evaluators, and data analysts, except for the intervention operators, who were not blinded. To ensure the proper implementation of blinding during the trial, the research unit designated personnel responsible for the allocation of instruments. The individuals involved in subject selection, efficacy and safety evaluation, and data analysis were not allowed to interact with the process of instrument allocation and usage. Unblinding will only occur after the completion of all trials and the subsequent statistical analysis. In emergency situations, such as when a serious adverse event occurs and it is impossible to determine whether it is related to the treatment instrument, and immediate knowledge is needed to decide on a rescue plan, early unblinding is required. Upon unblinding, the time, reason, and personnel involved in the early unblinding must be promptly recorded, and the monitor must be notified as soon as possible. Once unblinded, the subject can no longer continue in the study, and their trial data cannot be used for subsequent analysis, but they must still be included in the safety analysis dataset. Additionally, timely treatment and protection should be provided to the subject.
