Embodiment

[0027] In ERCP cases, anatomical variation of the digestive tract is possible. It is easy to "get lost" when the side-view mirror 1 enters, so a direct-viewing auxiliary device is installed. The fixture 4 of the device is set as a rubber tube to be inserted into the duodenoscope clamp channel 5 so that the connecting piece 3 and the glass auxiliary direct-view mirror 2 are closely attached to the lens of the duodenoscope side-view mirror 1, especially to make the glass The auxiliary direct-sight mirror 2 is well fixed on the observation hole in front of the lens of the duodenum side-view mirror 1. After obtaining a certain direct vision in front of the mirror body through the auxiliary direct vision mirror 2 of the direct vision auxiliary device, the operator seeks a cavity and enters the mirror. After entering the mirror to the operating area, he can use the contrast knife or Tools such as biopsy forceps remove the direct vision auxiliary device, so that the entire direct vi...

Abstract

The invention relates to a duodenoscope direct view auxiliary device, and belongs to the technical field of medical instruments. The duodenoscope direct view auxiliary device is arranged on a side view mirror at a backward viewing angle of 105 degrees of a duodenoscope, and comprises an auxiliary direct view mirror, a connecting piece and a fixing piece; the auxiliary direct view mirror comprisesa direct view mirror surface, and an included angle is arranged between the direct view mirror surface and the side view mirror for reflecting a picture in front of the duodenoscope into a lens of theside view mirror through the direct view mirror surface; the auxiliary direct view mirror is connected with the fixing piece through the connecting piece, and the fixing piece is connected with a duodenoscope body. By means of light reflection and the connecting and fixing devices, the side view mirror of the duodenoscope obtains a direct view field, operation is facilitated, and practicability is high; the device is simple and reliable in structure, low in cost, easy to produce and convenient to popularize and apply; and the feeding operation difficulty of the duodenoscope is reduced, safetyof ERCP is improved, and an operator can conveniently master the ERCP technology.

Description

technical field [0001] The invention relates to a duodenoscope direct vision auxiliary device, which belongs to the technical field of medical instruments. Background technique [0002] Duodenoscope is mainly used for a series of operations related to endoscopic retrograde cholangiopancreatography. The mirror is a side-view mirror with a viewing angle of 105° backward, and it is more difficult to operate than ordinary gastrointestinal mirrors. Endoscopic retrograde cholangiopancreatography (ERCP) refers to inserting a duodenoscope into the descending part of the duodenum, finding the duodenal papilla, inserting a contrast catheter into the opening of the papilla from the biopsy duct, and injecting contrast Post-dose X-ray film to show the technique of pancreaticobiliary duct. Because ERCP does not require surgery, the trauma is small, the operation time is short, the complications are less than surgery, and the hospital stay is also greatly shortened, so it is very popular ...
