Like the other diseases, early diagnosis is very important for the colon related diseases of the internal organs of the human body. Endoscopy is used for early detection of such diseases. Using endoscopy, polyps such as lesions of the colon polyp, which are likely to progress to colorectal cancer, are excised and tissue samples are collected. The tissue samples are analyzed through pathological examination or biochemical analysis to determine whether or not the colon is diseased . Therefore, endoscopic resection of polyps is essential for the prevention of gastrointestinal malignancies including colon cancer.

In general, there are two methods for collecting the collected tissue samples. Depending on the size of the polyps, there are two methods. When multiple polyps are collected, the lesions with a diameter of about 7 mm or more are collected and the endoscope is inserted into the cecum. do. However, the polygons of about 7 mm or less are sucked through a working channel provided in the endoscope body, collected through a suction tube connected to the endoscope body, and then collected. However, the suction tube connecting the working channel and the collecting tube has a small diameter and a curved shape, so that the tissue sample can not reach the collecting tube while being inhaled and moved, and adheres to the inner wall of the suction tube to collect the tissue sample The sample can not be collected or recovered, and the sample may be lost.

Currently, the method of collecting samples is to collect and collect the samples one by one in stool waste or suspended matter collected in the collecting port. In case of removing many kinds of polyps, there is a disadvantage that it takes a lot of time and takes a lot of time, There is a problem that requires the work force of an endoscopic assistant.

Therefore, there is a need for a method that allows tissue samples taken during endoscopic polypectomy procedures to be recovered intact without loss of tissue samples, and to recover quickly and conveniently.
