中文摘要：

随着微创外科的发展，腹腔镜技术和消化内镜技术均取得了迅猛的发展，但这两种技术应用于消化道疾病的诊断和治疗中均仍有不足之处。腹腔镜技术需经腹壁戳孔，易造成损伤；而消化内镜在检查过程中患者需承受较大痛苦，且不能进行精细的内镜下定位操作。

英文摘要：

With the development of minimally invasive surgery, great developments have been made in laparoscopic techniques and digestive endoscopy. However, laparoscopy may cause injury by abdominal puncture, and digestive endoscopy is a painful examination for patients and is difficult to localize the tumor. Magnetic anchor makes use of magnetic attraction in positioning, and it improves laparoscopy and endoscopy by external magnetic field or magnetic handle. Nowadays, combined application of magnetic anchor and laparoscope and endoscope in the treatment of digestive diseases has been accepted by many medical centers, and further researches need to be carried out to realize the aim （small trauma, little pain and quick recovery） of minimally invasive surgery.
