Novel gastroscope outer sleeving pipe

Abstract

The invention discloses a novel gastroscope outer sleeving pipe. The novel gastroscope outer sleeving pipe comprises a flexible sleeving pipe and a water injection pipe, a gastroscope channel is sleeved with the flexible sleeving pipe, a spiral temperature adjustment rubber hose is arranged between the flexible sleeving pipe and the gastroscope channel, a flushing pipeline is formed in the inner wall of the flexible sleeving pipe, the flushing pipeline is connected with a flushing pipe, the water injection pipe passes through a fixing ring and extends into the gastroscope channel, the upper portion of the fixing ring is provided with an occlusion pad, the occlusion pad is sleeved with a rubber check ring, the flushing pipe and an inflating pipe are installed on the upper portion of the occlusion pad, a heating device is arranged at the tail end of the inflating pipe, and the heating device is connected with an air pump through an air pipe. According to the novel gastroscope outer sleeving pipe, the mode that the gastroscope channel, the flexible sleeving pipe and the rubber hose are combined is adopted, esophagus damage caused by sharp foreign matter can be effectively avoided, the occlusion pad structure is adopted, air inflation and heating can be conducted through the rubber hose, the esophagus of a patient can be expanded, the patient can feel warm in stomach, and it is helpful to raise the success rate of an operation.

Description

Technical field [0001] The present invention relates to the technical field of medical devices, in particular to a new type of gastroscope overtube. Background technique [0002] At this stage of gastroscopic surgery, most of the operations are performed directly by inserting the gastroscope. Although this simple method is convenient and quick, the patient will have greater pain, especially for the removal of sharp foreign bodies by gastroscopy, which often damages the esophageal mucosa , And sometimes even cause perforation of the esophagus. If the operation cannot be performed in time, it will be life-threatening in severe cases. At present, a domestic gastroscope protective sleeve needs to be tied to the front end of the gastroscope. For gastroscopic surgery, it does not have a protective effect. In addition, it is easy to be pierced by sharp metal and other foreign objects, which may damage the esophagus. There are also some gastroscope protective sleeves with simple structur...

Problems solved by technology

[0002] Most gastroscopy operations at the present stage are directly inserted into the gastroscope for surgical operation. Although this simple method is convenient and quick, the patient will feel a lot of pain, especially when the gastroscopic removal of sharp foreign bodies is used, the esophageal mucosa is often damaged , and sometimes even cause esophageal perforation. If the operation cannot be performed in time, severe cases will be life-threatening. At present, a gastroscope protective sleeve in China needs to be bound to the front end of the gastroscope, and enters the throat with the gastroscope many times. For gastroscopic surgery, it does not have a protective effect. In addition, it is easy to be punctured by sharp metal and other foreign objects, thereby damaging the esophagus. There are also some gastroscopic protective sleeves with simple structure and no support at the end. During the operation, patients often Due to the long operation time, coughing and wriggling and slipping of the outer tube occurred
