Embodiment approach

[0070] figure 2 It is a schematic structural diagram of an outer sleeve 210 according to another embodiment of the present invention. Specifically, the overtube 210 of this embodiment discloses an embodiment of a fixing member, and the fixing member is a first balloon 222 . Specifically, the outer sleeve 210 of the present invention comprises a transparent observation cover 212, a side hole 214, a first balloon 222 and a steering piece 280, wherein the configuration of the transparent observation cover 212, the side hole 214 and the steering piece 280 is the same as The outer sleeve 110 shown in FIG. 1 is the same, so these components will not be repeated here.

[0071] It should be noted that the first balloon 222 is arranged on the outside of the overtube 210 and close to the side hole 214; when performing peroral cholangioscopic surgery, the first balloon 222 can be inflated to expand, and the outer tube 210 The front end rests against the body of the individual. In ano...

Abstract

An ultrathin endoscope auxiliary system includes an overtube (110) and a mouth piece (150). The overtube (110), which allows the ultrathin endoscope (160) to be inserted therein, includes a transparent cap (112), a side opening (114), a deflecting member (180) and a positioning member (120). The transparent cap (112) is disposed at the front end of the overtube (110); the side opening (114) is disposed on the overtube (110) and approximates to the front end of the overtube (110); whereas the deflecting member (180) is disposed within the overtube (110) and the positioning member (120) is disposed outside the overtube (110) and approximates to the side opening (114). The deflecting member (180) is capable of deflecting the ultrathin endoscope and thereby allows the ultrathin endoscope (160) to be extended outside the overtube (110) through the side opening (114). The mouth piece (150) works with the overtube (110) to adjust the length and the axial orientation of the overtube (110) in the subject.

Description

technical field [0001] The invention relates to the field of endoscopes, in particular to an auxiliary system for narrow-diameter endoscopes and its application. Background technique [0002] Due to the increasing number of biliary tract diseases, there is an urgent need for medical technology and equipment that can directly enter the bile duct to diagnose and treat biliary system diseases. Endoscopic retrograde cholangiopancreatography (ERCP, endoscopicretrograde cholangio-pancreatography) is an important tool for the diagnosis and treatment of biliary tract diseases. The well-known method of endoscopic retrograde cholangiopancreatography to observe lesions is to inject a contrast agent into the bile duct and then irradiate the disease to diagnose the disease. However, endoscopic retrograde cholangiopancreatography cannot directly observe the lesion like other endoscopic techniques, and can even magnify the image of the lesion or stain or section the lesion. In terms of t...
