Abstract
The utility model discloses a kind of reducing run-resistant stents of pancreatic duct, including stand tube main body, reducing end is fixed with stand tube main body, extension square diameter of the reducing end along reducing end tapers into；Some anticreeps are fixed with the reducing end to swell.Its is simple in construction for the utility model, easy to use, and stand tube is pruned to change caliber, simultaneously multiple structures that swell can increase adhesive force between stand tube and ductus pancreaticus, adhere to both more firm, so as to prevent stand tube from deviating from from ductus pancreaticus, improve success rate of operation and patient's postoperative quality of life.
Description
Technical field
It the utility model is related to technical field of medical instruments, and in particular to a kind of reducing run-resistant stents of pancreatic duct.
Background technology
In the operation of the diseases such as treatment cancer of pancreas, it is often necessary to pancreas and intestinal anastomosis are carried out, wherein being put in ductus pancreaticus
Put ductus pancreaticus reducing run-resistant stents of pancreatic duct and carry out the committed step that pancreatic juice drainage is operation.Existing ductus pancreaticus reducing run-resistant
Stents of pancreatic duct is made of silica gel, and caliber is of single specification, as patient's ductus pancreaticus is easily oppressed compared with detailed rules and regulations reducing run-resistant stents of pancreatic duct
Ductus pancreaticus causes its ischemic necrosis, and as patient's ductus pancreaticus is thicker, reducing run-resistant stents of pancreatic duct then easily slips；In addition mesh
Preceding ductus pancreaticus reducing run-resistant stents of pancreatic duct smooth surface, without anti-fall function, although seam can be used in operation
It is legal to be fixed, but the incidence of ductus pancreaticus reducing run-resistant stents of pancreatic duct abjection is still very high, causes exocrine pancreas
It is obstructed, and then causes pancreatitis and pancreatic exocrine insufficiency or even lose, has a strong impact on prognosis and the existence matter of patient
Amount.
Utility model content
The purpose of this utility model is to provide a kind of reducing run-resistant stents of pancreatic duct to solve the above problems.This practicality
New its is simple in construction, and easy to use, stand tube is pruned to change caliber, at the same it is multiple swell structure can increase stand tube and
Adhesive force between ductus pancreaticus, adhere to both more firm, so as to prevent stand tube from deviating from from ductus pancreaticus, improve success rate of operation
And patient's postoperative quality of life.
To achieve the above object, the technical solution of the utility model is：
A kind of reducing run-resistant stents of pancreatic duct, including stand tube main body, reducing end is fixed with stand tube main body, it is described
The reducing end square diameter of the extension along reducing end tapers into；Some anticreeps are fixed with the reducing end to swell.
Further to improve, the stand tube main body, reducing end and anticreep swell integrally formed.
Further to improve, the stand tube main body, reducing end and anticreep are swelled as silica gel material.
Further to improve, the anticreep swells stepped arrangement.
Further to improve, the anticreep is swelled as curved surface ring-type.
Further to improve, the anticreep swells to be uniformly distributed along the bearing of trend at reducing end.
Further to improve, projection is formed with force section in the stand tube main body.
The advantages of the utility model：
Compared with prior art, the utility model reducing run-resistant stents of pancreatic duct has simple in construction, easy to use, can
Stand tube is entered into pancreas end according to patient's ductus pancreaticus caliber to be trimmed to pipe diameter size when while multiple swell increase stand tube and pancreas
Adhesive force between pipe, adhere to both more firm, prevent stand tube from deviating from from ductus pancreaticus, improve success rate of operation and patient
The advantages that postoperative quality of life.
Brief description of the drawings
Fig. 1 is cross-sectional view of the present utility model.
Embodiment
Following examples are used to illustrate the utility model, but are not limited to the scope of the utility model.
Embodiment 1
A kind of reducing run-resistant stents of pancreatic duct as shown in Figure 1, including stand tube main body 1, it is fixed in stand tube main body 1
There is reducing end 2, extension square diameter of the reducing end 2 along reducing end 1 tapers into；It is fixed with the reducing end 2 some
Anticreep swells 3.
It is integrally formed that stand tube main body 1, reducing end 2 and anticreep swell 3.
It is silica gel material that stand tube main body 1, reducing end 2 and anticreep, which swell 3,.
Anticreep swells 3 stepped arrangements.Anticreep swells 3 and is uniformly distributed along the bearing of trend at reducing end 2.Anticreep swells 3
Preferably curved surface ring-type.Projection is formed with force section 4 in stand tube main body 1, is easy to hand force that reducing end 2 is pushed into ductus pancreaticus.
In surgical procedure, stand tube is trimmed using scissors 5 according to patient's ductus pancreaticus pipe diameter size and enters pancreas end, the length cut off is got over
Long, stand tube caliber is bigger.Stand tube, which enters pancreas end, multiple adhesive force swelled between increase stand tube and ductus pancreaticus, makes both attached
It is more firm, while is easier to be fixed by surgical thread, prevents stand tube from deviating from from ductus pancreaticus.
Although above having made detailed description to the utility model with generality explanation and specific embodiment,
On the basis of the utility model, it can be made some modifications or improvements, this is apparent to those skilled in the art
's.Therefore, the these modifications or improvements on the basis of without departing from the utility model spirit, belonging to the utility model will
Seek the scope of protection.
