Internal drainage tube used after pancreatic operation

Abstract

The internal drainage tube structurally comprises a drainage bottle, a connector, an indicator, a drainage tube body and a limiting device.When the internal drainage tube is used, an outer tube body penetrates through and extends into a wound, after the outer tube body extends to a certain position, the outer wall of a contact sealing piece can be connected with the inner edge of the wound in a matched mode, and the outer wall of the contact sealing piece and the inner edge of the wound can be in a sealed state; a movable rod on a locking clamping piece is rotated, the movable rod can move and stretch into a positioning groove, the outer tube body is effectively clamped and limited, the outer tube body is not prone to shifting, cell tissues in the pancreatic juice are blocked through a filter screen, and the pancreatic juice is prevented from flowing out of the gap between the wound and the drainage tube. And cell tissues are prevented from flowing into the tube body to cause blockage, so that the drainage tube can stably and smoothly conduct drainage treatment on pancreatic juice.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an internal drainage tube for pancreatic surgery. Background technique [0002] With the continuous development of endoscopic technology and the continuous improvement of its accessories, duodenoscopic technology has become an important measure for the treatment of hepatobiliary and pancreatic diseases. Endoscopic nasobiliary drainage is a routine technique in ERCP operations and can be directly applied In the treatment of obstructive jaundice, acute suppurative cholangitis, bile leakage and other diseases, it can reduce the probability of postoperative pancreatitis and cholangitis, and can observe the properties and outflow of bile. When using the internal drainage tube, it needs to be improved. place: [0003] When using the drainage tube, it is necessary to insert the drainage tube vertically into the pancreas to drain the pancreatic juice. Since most of the existing ...

AI Technical Summary

Problems solved by technology

[0003] When using the drainage tube, it is necessary to insert the drainage tube vertically into the pancreas to drain the pancreatic juice. Since most of the existing pancreatic juice drainage tubes are vertical tubes, the vertical drainage tube cannot be tightly attached to the edge of the wound when inserted into the pancreas. The pancreatic juice often flows out from the gap between the wound and the vertical drainage tube. The pancreatic juice secreted by the pancreas is highly corrosive, which can easily affect the normal functions of surrounding tissues and organs, resulting in complications for patients.
