At previous anastomotic, and make will not floating in bile duct through jejunum far from identical one end for inner drainage tube, to avoid because of interior drainage
Pipe, which is floated, causes patient's hepatapostema and Cholangio- jejunostomy stenostomia into liver, is conducive to patient's early recovery.
The utility model embodiment is described in detail with reference to the accompanying drawing.
Detailed description of the invention
Fig. 1 is the perspective view of the utility model embodiment inner drainage tube component；
Fig. 2 is the half sectional view of the utility model embodiment inner drainage tube component；
Fig. 3 is the pancreas Surgical healing effect picture when inner drainage tube component of the utility model embodiment uses.
Specific embodiment
As shown in Figure 1 and Figure 2, the inner drainage tube component of Pancreaticoenterostomy respectively provided by the embodiment of the utility model
Perspective view and half sectional view, as seen from Figure 1, Figure 2, the inner drainage tube component of the Pancreaticoenterostomy of the utility model embodiment
Include: the inner drainage tube for being placed in ductus pancreaticus, there is hollow section and solid-section；Setting is in inner drainage tube outer wall and is located at interior
The fixed structure for being fixed on inner drainage tube at pancreas intestinal anastomotic stoma of the hollow section of flow tube；The solid of inner drainage tube is set
The anti-drift structure for preventing inner drainage tube from floated in bile duct through jejunum of section end.
Specifically, the inner drainage tube of the present embodiment is divided into two sections, that is, have hollow section 1 and solid-section 3, the one of hollow section 1
Part is plugged in pancreas 9, multiple conduction holes 6 that inner drainage tube is extended radially through along inner drainage tube is arranged in hollow section 1, by drawing
Discharge orifice drains pancreatic juice.In order to allow the hollow section 1 of inner drainage tube to be fixed on the ductus pancreaticus of pancreas 9 and previous anastomotic (this Shen of jejunum
Please be referred to as pancreas intestinal anastomotic stoma) at, fixed structure is arranged in the outer wall of inner drainage tube hollow section 1 in the present embodiment.Preferably, this reality
The fixed structure for applying example includes: to be nested in inner drainage tube outer wall and close to the fixed ear 2 of its 1 origin or beginning of hollow section；It is provided with fixation
On ear 2 and it is symmetrically positioned in a pair of of fixation holes 7 of inner drainage tube two sides；Be fed through a pair of of fixation hole 7 for inner drainage tube to be consolidated
Be scheduled on pancreas close to the suture 8 (as shown in Figure 3) on the antetheca and rear wall at pancreas intestinal anastomotic stoma.Wherein, fixed ear 2 is in strip
Shape, a fixation hole 7 is respectively set in both ends, and suture 8 is using the suture of medical nonabsorable.
Fixed ear 2 is fixed at pancreas intestinal anastomotic stoma, by suture 8 so that inner drainage tube is fixed on pancreas by the present embodiment
At intestinal anastomotic stoma.When design, fixed ear can also can be fixedly mounted with inner drainage tube one-pass molding by bonding or other means
On the outer wall of inner drainage tube.Preferably, fixed ear be arranged in inner drainage tube hollow section 1 away from end 10cm at.
Wherein, due to ductus pancreaticus and intestinal anastomosis, jejunum is again and bile duct is identical, therefore, the part of inner drainage tube in order to prevent
After hollow section 1 is inserted into the ductus pancreaticus of pancreas 9, the part inner drainage tube exposed to outside pancreas 9 floats in bile duct through jejunum, this implementation
Also anti-drift structure is arranged in the solid-section of inner drainage tube in example.Preferably, anti-drift structure includes: to be arranged in inner drainage tube outer wall
And it is located at the protrusion 4 of its 3 end of solid-section；It is successively provided with along the axial direction of inner drainage tube more in inner drainage tube solid-section 3
A blocked hole 5 or clamping groove；Wherein, a part of protrusion 4 can holding in any one blocked hole 5 or clamping groove.
Preferably, as shown in Figure 1-Figure 3, protrusion 4 can rounded or elliposoidal, and the outer diameter of protrusion 4 is greater than
The outer diameter of inner drainage tube, is nested with outside solid-section and close to 3 end of inner drainage tube solid-section, and the extrados of protrusion 4 can be with card
Hole is connect to coincide.Alternatively, protrusion can be hemispherical or semielliptical shape, protrusion outer diameter is greater than the outer diameter of inner drainage tube, protrusion
The extrados in portion 4 can coincide with blocked hole, be plugged on (not shown) in blocked hole or clamping groove.
When design, blocked hole can be for the through-hole for wearing inner drainage tube solid-section, clamping groove can drain inside for setting
The extending direction of the arc groove of pipe solid-section opposite side, blocked hole and clamping groove can be identical as the length extending direction of fixed ear,
So as to when fixed ear is fixed at pancreas intestinal anastomotic stoma, the solid-section of drainage tube can bending, then make protrusion holding in card
It connects in hole or clamping groove.
Preferably, the diameter of protrusion is greater than the inner drainage tube 2mm of pancreas intestines, and the quantity of blocked hole or clamping groove can be 3
It is a, and the radius for being clamped bore dia or clamping groove is equal to or slightly less than the diameter of inner drainage tube, protrusion 4 away from fixed ear about
15cm。
After inner drainage tube hollow section is placed into ductus pancreaticus, the nonabsorable suture of pancreas intestinal anastomotic stoma front and rear wall passes through respectively
Aperture in fixed ear, fixed ear is fixed, so that inner drainage tube suture is fixed in pancreas.Then according to Cholangio- jejunostomy mouth
Size, adjustment inner drainage tube solid-section is bent into the size (as shown in Figure 3) of ring set, the diameter of ring set made to be greater than bile duct and sky
The diameter of intestinal anastomotic stoma (abbreviation Cholangio- jejunostomy mouth), then the protrusion holding on inner drainage tube is made in blocked hole or clamping groove
Ring set is fixed, and ring set is effectively prevent to float in liver by Cholangio- jejunostomy mouth.
In conclusion compared with prior art, the inner drainage tube component of the Pancreaticoenterostomy of the utility model embodiment
It has the advantages that
The inner drainage tube component of the present embodiment, structure is simple, the inner drainage tube of Pancreaticoenterostomy can be fixed on pancreas intestines
At previous anastomotic, and make will not floating in bile duct through jejunum far from identical one end for inner drainage tube, to avoid because of interior drainage
Pipe, which is floated, causes patient's hepatapostema and Cholangio- jejunostomy stenostomia into liver, is conducive to patient's early recovery.
Although being explained in detail above to the utility model embodiment, the utility model embodiment is without being limited thereto, this
Those skilled in the art can modify according to the principle of the utility model embodiment, therefore, all practical new according to this
The various modifications that the principle of type embodiment carries out all should be understood as falling into the protection scope of the utility model embodiment.
