Run through between the gap of set 16 in relaxed state.1 front end of particle conduit is not deformed by 11 pulling force of bracing wire.When particle conduit 1 exists
Patient's body via biliary tract inside, and the front end of particle conduit 1 enters duodenum interior lumen intersection.Pull back bracing wire
Loop line 13, so that 1 front end stress of particle conduit is formed by bending barb-like, spiral winding 3 follows the synchronous bending of particle conduit 1 to become
Shape.The barb-like of 1 front end of particle conduit will block duodenum and biliary tract river conjunction inside duodenum, so that particle is led
Pipe 1 will not slide backward, by 13 end point of bracing wire loop line be equally wound to the inside of guy winding pin 17 and with bracing wire fixing sleeve 16
Clamping, so that the bending of 1 front end of particle conduit keeps stablizing.Under the support of spiral winding 3 biliary tract internal chamber wall and particle conduit 1 it
Between have gap, bile is flowed and enters the inside of main chamber 6 of particle conduit 1 from bile hole 9 and from 1 inside stream of particle conduit
Enter in duodenum.The particle in particle conduit 1 carries out radiotherapy to the tumour in biliary tract region at the same time.
The innovative technology point and beneficial effect of the utility model at least that:
1. particle conduit 1 uses three chamber segment structures of the smooth connection of cylindrical section, particle conduit 1 has stronger deformation characteristic,
And allow particle storehouse 7 be arranged in 6 two sides of main chamber can and meanwhile good the effect of radiation therapy can be played to the tumour of biliary tract two sides,
It is anti-slip can to play the role of closure to particle storehouse 7 in the flakey particle warehouse lid 8 of 5 opening of particle storekeeper setting.
2. being cased with spiral winding 3 in the periphery of particle conduit 1, spiral winding 3 can follow the synchronous bending of particle conduit 1 to become
Shape can play support to biliary tract inner wall using spiral winding 3 and extend out effect, prevent biliary tract inner wall is from being close to particle conduit 1,
Bile is allowed to flow into main chamber 6 from the equally distributed bile hole 9 in 1 winner's lumen of particle conduit, 4 wall two sides to flow into ten
Auxiliaring effect is played to food digestion inside two duodenum 12, the conventional particle conduit 1 effectively solved causes cholestasia after being passed through
Situation.
3. particle conduit 1 be passed through bracing wire 11 inside main chamber 6 and bracing wire 11 from the bracing wire of 1 front end of particle conduit stretches out hole
It is stretched out at 12 and enters main chamber 6 from the bile hole 9 of certain distance rearward and extend to form bracing wire time from 1 rear end of particle conduit
Line 13, by pull bracing wire loop line 13 can make 1 front end bending deformation of particle conduit at it is barb-like can be in biliary tract and 12
Duodenum 12 intersection is blocked so that particle conduit 1 will not be slipped in treatment.
4. what 1 changeover portion of particle conduit was cased with tightens label circle 2 can slidably reciprocate on particle conduit 1, so that tightening
The effect of label 2 existing contrast labels of circle, and constraint can be played the role of to particle warehouse lid 8, it tightens label circle 2 and is provided with positioning
Hole 21 cooperates positioning pin that can play fixed effect to the position for tightening label circle 2, to can guarantee that particle warehouse lid 8 will not take off
2 are enclosed from label is tightened.
5. 15 1 side connector of three-way connection of 1 rear end of particle conduit connection is connected with bracing wire fixing sleeve 16, bracing wire is solid
Surely the bracing wire of set 16 winds 11 stroke of bracing wire and is clamped so that bracing wire by seam 18 and the cross gap 20 of guy winding pin 17
11 are strained and fixed, and particle conduit 1 is bent, and fixation is stuck in duodenum and biliary tract river conjunction reaches particle conduit 1 and fixes
Effect, doctor's both hands can be liberated, it is effective to reduce doctor's working strength.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
