Abstract

The invention relates to a transparent cap for assisting digestive endoscopic resection, which includes an insertion tube, a support structure and an adjustment bracket. It is characterized in that the transparent cap also includes a pulling structure for changing the inner diameter of the adjustment bracket, the support structure supports the adjustment bracket, and the support structure and the adjustment bracket are arranged on the same side of the insertion tube, inside or outside the insertion tube . In addition, the transparent cap is also provided with a disposable insulating rubber ring which is placed on the lesion position during use. The variable inner diameter transparent cap of the present invention is a medical device used in assisting digestive endoscopic resection, which can adjust the size of the inner diameter at any time according to the size of the diseased tissue, so it can be more widely used in endoscopic resection of different sizes of diseased tissue Medium, and easy to use.

Description

technical field [0001] The invention belongs to an auxiliary medical device used in the use of digestive endoscope, in particular to an auxiliary medical device used in endoscopic resection, in particular to a transparent cap for assisting digestive endoscopic resection. Background technique [0002] my country is a country with a high incidence of gastrointestinal tumors, and among the top five most common malignant tumors, gastrointestinal tumors occupy three seats, namely gastric cancer (2nd), colorectal cancer (4th) and esophageal cancer (5th). ). At present, the strategic policy of cancer prevention and treatment in my country has been determined as "moving the gate forward and moving the center of gravity downward". Early detection of digestive tract tumors has become the core of clinical and scientific research. With the popularization of endoscopic screening and the improvement of diagnostic techniques, more and more early gastrointestinal tumors will inevitably be d...
