研究目的:

与传统的腹腔镜或者外科手术中可以多人多器械合作进行手术不同,目前治疗胃镜仅有一条操作通道,直径仅为3.2m,而进行ESD剥离必须使用的附件例如粘膜下注射针、粘膜切开刀、热活检钳、止血夹等器械均需要通过此通道进入胃内,且因通道直径限制,每次只能进入一种器械进行操作。临床使用最为广泛的治疗胃镜只能进行单通道或者单人操作,这极大的限制了内镜切除技术的发展和普及推广。在ESD治疗过程中引入第二只“手”甚至多只“手”进行辅助是早期胃癌ESD治疗必须克服的技术鸿沟,也是内镜微创治疗技术进行迭代发展的必经之路。本项目拟在ESD治疗早期胃癌的过程中引入新型辅助设施,通过多种不同的牵引技术辅助,清晰地暴露粘膜下层的操作界面,降低治疗内镜头端进入粘膜下层并维持良好清晰手术视野的难度,达到缩短手术时间、降低围手术期并发症发生率、提高早期胃癌治愈性切除率的目的。  

Objectives of Study:

Unlike traditional laparoscopic or surgical procedures where multiple people and instruments can collaborate for surgery, currently there is only one operating channel for treating gastroscopy, with a diameter of only 3.2m. Accessories that must be used for ESD dissection, such as submucosal injection needles, mucosal incisors, thermal biopsy forceps, hemostatic clips, etc., all need to enter the stomach through this channel, and due to channel diameter limitations, only one instrument can be entered at a time for operation. Although dual channel endoscopes have been developed abroad, the vast majority of hospitals in China are unable to obtain and use them due to their high purchase and maintenance costs. The most widely used treatment for gastroscopy in clinical practice can only be performed with a single channel or single person operation, which greatly limits the development and popularization of endoscopic resection technology. How to introduce a second or even multiple hands for assistance in ESD treatment is a technical gap that must be overcome in early gastric cancer ESD treatment, and it is also a necessary path for the iterative development of endoscopic minimally invasive treatment technology.This project aims to introduce new auxiliary facilities in the process of ESD treatment for early gastric cancer. Through various traction techniques, the operating interface of the submucosal layer is clearly exposed, reducing the difficulty of entering the submucosal layer and maintaining a good and clear surgical field of view during treatment. The goal is to shorten surgical time, reduce the incidence of perioperative complications, and improve the curative resection rate of early gastric cancer.
