Description
Technical field
The present invention relates to the anti-biliary tract racks that backflows of one kind.More particularly to a kind of anti-biliary tract rack that backflows of valve.
Background technique
Biliary duct stricture is the common complication of disease of digestive tract, although biliary tract rack come out for many years and clinically extensively
It is obtained generally using but biliary tract backflows initiation that infection is still the serious problems left, strong influence patient's
Quality of life and chances of survival.When bile duct causes obstruction because of reasons such as Stone obstruction, cicatricial stenosis, tumours, surgeon is normal
Often the bile duct of obstructive position nearside and intestines are directly connected to, bile is enable to flow directly to enteral by this interface, this
Kind operation is known as biliary enteric anastomosis.Intestines gallbladder anastomosis operation destroys sphincter, and the bacterium foreign matter etc. in duodenum can enter gallbladder
Road.It may result in infection of biliary tract, the complication such as gall stone.Not only weaken the clinical effectiveness for the treatment of, can also be caused to patient
Serious pain and loss.Traditional solutions be it is anti-infective, effect is not satisfactory.Research with practice have shown that, using anti-reflux gold
It is technically feasible for belonging to the corresponding disease of stent in the treatment, and is safely effectively.If can after intestines gallbladder anastomosis
Anti-reflux human biliary duct's bracket is placed, very big possibility is improved postoperative complications and improves patient and treats experience.Therefore, urgently
It needs that anti-reflux human biliary duct's bracket is carried out going deep into system research, this will have to a kind of novel alleviation Duodenal-biliary reflux method is started
There is important theory significance.
Summary of the invention
The technical problem to be solved by the invention is to provide one kind effectively to generate to reflux object when backflowing
The anti-biliary tract rack that backflows of the valve of blocking.
The technical scheme adopted by the invention is that: a kind of valve anti-backflow biliary tract rack, including rack body, it is described
The identical valve of a pair of of structure is symmetrically arranged in rack body, the valve is by being the piece knot of arcuation in length and width
The main body of structure and it is integrally formed in the main body two sides respectively and is constituted with the perpendicular side of main body, the chip architecture of the arcuation
One end of main body forms arc side identical with the rack body inner sidewall radian, the arc side and corresponding rack body
Inner sidewall be integrated connection, the other end of the chip architecture main body of the arcuation is straight flange, the straight flange of a pair of valve be with
The central axis of the rack body is line of symmetry and is in an open state in bile proper flow that Gallbladder is when occurring
Closed state is symmetrical arranged, and two sides of the valve are integrated with the inner sidewall of corresponding rack body to be connect.
Two sides that the valve is corresponded in the rack body are formed with two sides with the valve
The sprue that integrally connected is used to prevent bile from circulating.
Two sides of the valve include with the main body of arcuation chip architecture it is perpendicular for preventing from reversed excessively becoming
The reinforcement side of shape, and 2 or more the grooves deformed for increasing forward direction being formed on the reinforcement side, the reinforcement side
It is integrated and connect with the inner sidewall of the rack body.
Rack body, valve and the sprue is formed by silica gel integrated injection molding.
A kind of anti-biliary tract rack that backflows of valve of the invention, the results show that can be when backflowing through finite element modelling
Barrier effect effectively is generated to reflux object.The present invention can slow down hidden sphincter failure after intestines gallbladder anastomosis operation and caused by intestines
Gallbladder backflows phenomenon, reduces infection rate, reduces influence of the operation to patient's normal life, improves the survival rate and comfort level of patient.

Specific embodiment
A kind of anti-biliary tract rack that backflows of valve of the invention is described in detail below with reference to embodiment and attached drawing.
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of valve of the invention anti-backflow biliary tract rack, including rack body 1, it is described
Rack body 1 in be symmetrically arranged with the identical valve 2 of a pair of of structure, the valve 2 is by being arcuation in length and width
Chip architecture main body 24 and be integrally formed in 24 two sides of main body and the side 23 perpendicular with main body 24 respectively and constitute, institute
The one end for stating the chip architecture main body 24 of arcuation forms arc side 21 identical with the 1 inner sidewall radian of rack body, the arc
Side 21 is integrated with the inner sidewall of corresponding rack body 1 and connect, and the other end of the chip architecture main body 24 of the arcuation is straight
The straight flange 22 on side 22, a pair of valve 2 is using the central axis of the rack body 1 as line of symmetry and in bile normal stream
It is in an open state when dynamic, what Gallbladder occurred to be in off state when (duodenum content backflows) is symmetrical arranged, described
Two sides 23 of valve 2 are integrated with the inner sidewall of corresponding rack body 1 to be connect.
As shown in Figure 1 and Figure 2, corresponded in the rack body 1 valve 2 two sides 23 be formed with
The sprue 3 that two 23 integrally connecteds of side of the valve 2 are used to prevent bile from circulating.
As shown in Figure 1, Figure 3, two sides 23 of the valve 2 include perpendicular with the main body 24 of arcuation chip architecture
For preventing the reinforcement side 231 of reversed excessive deformation, and be formed on the reinforcement side 231 2 or more for increasing
The groove 232 of forward direction deformation, the reinforcement side 231 is integrated with the inner sidewall of the rack body 1 to be connect.The side 23
In bile proper flow, valvular deformity is positive deformation, so that bile be made to flow through；The side 23 is in Gallbladder
It is deformed into reversal deformation, contacts two straight flanges 22 of valve 2 tighter, to prevent biliary regurgitation.
In a kind of anti-biliary tract rack that backflows of valve of the invention, the rack body 1, valve 2 and sprue 3 be by
Silica gel integrated injection molding forms.
A kind of working principle of the anti-biliary tract rack that backflows of valve of the invention is, when 4 forward flow of bile, outside valve 2
Side stress, deforms, and generates gap among two panels valve 2, flows through as shown in Figure 4 for bile 4；When backflowing, in valve 2
Side generates reversal deformation, mutual extrusion occurs between two panels valve 2, shuts access, intestines gallbladder since the impact of reflux object receives pressure
The object 5 that backflows cannot flow through, as shown in Figure 5.To reach anti-reflux effect.
