Abstract
The invention relates to the technical field of medical apparatus and instruments, and in particular relates to a pancreatic duct stent capable of being taken out easily. The pancreatic duct stent comprises a drainage tube, an upper positioning bracket arranged on the upper end of the outer wall of the drainage tube and having a downward opening, a lower positioning bracket arranged on the lower end of the outer wall of the drainage tube and having an upward opening, and an annular shallow groove and a straight shallow groove which are communicated with each other and formed in the outer wall of the lower end of the drainage tube, wherein a thin nylon wire is fixed in the shallow grooves, and downwards extends to exceed the lower end of the drainage tube. According to the pancreatic duct stent capable of being taken out easily, through the thin nylon wire, the actual effective length is increased, and when internal shift occurs, the nylon wire can be directly grabbed, and then the drainage tube is safely and effectively taken out.
Description
Background technology
Owing to intestinal tube smooth muscle and the sphincteral contraction of vater's papilla can cause the peristalsis of intestinal tube and ductus pancreaticus, and the resilience that stents of pancreatic duct morphosis causes, and then cause that drainage tube (1) moves to far-end and come off in ductus pancreaticus, even completely into duodenum, cause drain failure, duodenum perforation even occurs；It is likely to and causes that drainage tube moves proximally to, be slid completely in ductus pancreaticus, be difficult to reclaim if stents of pancreatic duct is slid completely in ductus pancreaticus, if not reclaiming support, it may happen that the severe complications such as the damage of permanent ductus pancreaticus, pancreatemphraxis or generation acute pancreatitis.
Summary of the invention
Below in conjunction with drawings and Examples, stents of pancreatic duct of the present invention is further illustrated
Fig. 1 is the perspective view of stents of pancreatic duct of the present invention
In figure 1, drainage tube, 2, the holder of upper location, 3, the holder of lower location, 4, shallow circular recess, 5, straight shallow grooves, 6, thin nylon wire.
Detailed description of the invention
The easy taking-out type ductus pancreaticus drain plastic stent of stents of pancreatic duct of the present invention, it includes drainage tube (1), upper location holder (2) that drainage tube (1) outer wall upper end open is downward, drainage tube (1) outer wall lower ending opening lower location holder (3) upwards, lower location holder (3) top drainage tube (1) outer wall has shallow circular recess (4), lower location holder (3) offside drainage tube (1) outer wall has straight shallow grooves (5) and communicates with shallow circular recess (4).Thin nylon wire (6) is fixed in shallow circular recess (4) and straight shallow grooves (5) and extends downward beyond drainage tube (1) lower end.
Claims (3)
1. easily taking-out type ductus pancreaticus drain plastic stent includes drainage tube (1), upper location holder (2) that drainage tube (1) outer wall upper end open is downward, drainage tube (1) outer wall lower ending opening lower location holder (3) upwards, it is characterized in that: drainage tube (1) lower end outer wall has shallow circular recess (4) and the straight shallow grooves (5) of mutual traffic having thin nylon yarn (6) fixing in groove and extend downward beyond drainage tube (1) lower end.
