翻译为英文：接下来我会简要介绍这个临床试验方案的设计。它是一个前瞻性、多中心、随机、阳性平行对照试验与目前市面上的普通腔镜系统进行对照受试者将被随机分为2组分别接受两种器械进行治疗。

Next, I will briefly introduce the design of this clinical trial protocol. It is a prospective, multicenter, randomized, positive parallel-controlled trial, comparing it with the conventional laparoscopic system currently available on the market. The subjects will be randomly divided into two groups and receive treatment with two different instruments.
