Gastrointestinal stents mainly include esophageal stents, biliary stents, pancreatic stents, and intestinal stents. Esophageal stents are mainly used for esophageal stenosis caused by esophageal cancer, biliary stents are mainly used for biliary obstruction caused by cholangiocarcinoma, pancreatic stents are mainly used for pancreatic decompression during acute pancreatitis, and intestinal stents are mainly used for intestinal stenosis caused by colon cancer.

During laparoscopic surgery, sufficient hemostasis is essential to ensure a clear view of the surgical area. It is fundamental for the surgeon to carefully dissect and identify the vascular structure for primary prevention of bleeding before separating it as needed using various laparoscopic devices.

Endoscopic stapler medical equipment, mainly used for gastrointestinal anastomosis. It consists of a gun shaped stapler and an elastic fixing clip, characterized by simple operation, minimal trauma, and fast postoperative recovery.

Intestinal stent is a medical device, usually a tubular structure made of metal or plastic, used to solve gastrointestinal obstruction caused by intestinal stenosis or occlusion. 

There are many reasons for gastrointestinal obstruction, and the most common ones are patients with various malignant tumors, especially gastrointestinal malignant tumors. According to incomplete statistics, about 30% of patients with digestive tract tumors will experience varying degrees of obstruction, which directly leads to the inability of patients to eat normally, accompanied by abdominal pain, bloating, and in severe cases, gastrointestinal perforation, and even life-threatening conditions.

ERCP, known as the jewel on the crown of digestive endoscopy, has recently introduced a set of duodenoscopy equipment and successfully performed endoscopic retrograde cholangiopancreatography (ERCP)+biliary stent implantation for an 85 year old patient, relieving biliary obstruction caused by malignant tumors of the common bile duct and establishing a pathway for the patient to regain their life.

The indications for gastrointestinal stent placement surgery mainly include esophageal stricture, biliary stricture, intestinal obstruction, etc. Gastrointestinal stents mainly include esophageal stents, biliary stents, and intestinal stents.

At present, both abroad and domestically, the method used for disinfection of CPAP ventilators is commonly known as ozone. The respirator disinfection kit is essentially an ozone generator designed for CPAP respirator disinfection. Previously, the disinfection kit mainly used lithium batteries instead of regular batteries, which can be used for a month (disinfected once a week) when fully charged.

Respirator Disinfectant Guard is a home medical product that thoroughly disinfects the external pipes of the ventilator and the internal parts of the nose mask that contain bacteria and viruses.

The disposable laparoscopic cutting stapler is suitable for tissue transection, resection, and anastomosis in thoracic surgery, abdominal surgery, and gynecological surgery.
