The present invention relates to a kind of rechargeable type particle conduit.
Background technology
In conventional clinical practice, for some lose operative chance or be not suitable for surgical procedure, because tumour causes
Pernicious cavity obstruction patient, place conduit be a kind of clinically conventional treatment method.It is only to play nasal feeding to place conduit
Or the effect of drainage, get through normal physiological pipeline, but can not play a part for the treatment of tumour, it is impossible to contain tumour after
Supervention exhibition.
The patent No. 2014103438569 discloses a kind of medical particle conduit, the medical particle conduit include movable set in
Radioactive particle fixing device used in oncotherapy is provided with supravasal sleeve pipe, sleeve pipe, it is when in use, solid in particle
Determine to load radioactive particle in device, introduce a catheter into vivo, adjustment conduit particle apparatus is to cavity knub position, and the particle is led
Pipe not only acts as the effect of nasal feeding or drainage, and radioactive particle can also play a part of interior irradiation to tumour.But, in patient
Tumour occurs after partial remission, and radioactive particle and the spacing of tube wall tumour are increased, it is impossible to be in close contact tumour again, be have impact on and put
The therapeutic action of penetrating property particle, does not reach the highly conformable purpose of radiotherapy.
The content of the invention
The technical problem to be solved in the present invention is：There is provided one kind can change and highly conformable, intracavitary radiotherapy with tumour knurl body
The more preferable rechargeable type particle conduit of effect.
In order to solve the above problems, the present invention includes being drainage cavity, described conduit inside catheter body, catheter body
It is provided with body and is filled with passage and is looped around utricule in catheter body, described one end for being filled with passage is provided with valve body, filled
The other end for entering passage is connected with utricule, and radioactive particle is provided with described utricule, when balloon inflation, the utricule of expansion
Drainage cavity will not be extruded.
For the ease of fixed particle, particle of the present invention is pasted on the outer wall of utricule, and bullet is also arranged with outside utricule
Property protective jacket, when balloon inflation or contraction, spring protective set is with the corresponding expansion or shrinkage of utricule, and all particles are respectively positioned on elasticity
In protective jacket.
For the ease of fixed particle, particle of the present invention is pasted on the inwall of utricule.
Pocket type particle storehouse is provided with particle, utricule of the present invention for the ease of installing to place, described pocket type grain
Sub- storehouse is that outer wall of other edges with utricule on the elastic module for being pasted onto utricule surface, elastic module in addition to top edge glues
Knot, described particle is inserted into pocket type particle storehouse.
In order to avoid utricule, in expansion, influence particle is dropped out from pocket type particle storehouse, is also set outside utricule of the present invention
Described elastic protection layer is equipped with, described all pocket type particle storehouses are respectively positioned in elastic protection layer.
For the ease of being charged and discharged gas to utricule or liquid, valve body of the present invention includes being filled with mouth, is filled with mouth and inserts
Enter in passage is filled with, the inner chamber for being filled with mouth is provided with more pieces of resilient sealing flap, it is described when being filled with mouth in the raw
More pieces of resilient sealing flap, which is brought into close contact and sealed, is filled with passage, is filled with the outer surface of mouth and is provided with multi-turn along being filled between mouth axial direction
Every the sealing projection of arrangement, be filled with passage it is external be filled with mouth and be filled with the bound fraction of passage be also cased with elastic fastening set.
In order to be easy to catheter body importeding into body cavities, the bottom of catheter body of the present invention is set
It is cavity to have in nose cone or round blunt, described nose cone or round blunt, and described cavity is connected with drainage cavity, and drainage is empty
The side of chamber is provided with drainage side opening, and the top of cavity is provided with seal wire through hole.
In order to avoid delaying treatment cycle, particle conduit is clinically directly used, spacer sleeve is gone back outside described utricule
Provided with the adapter sleeve for avoiding balloon inflation.The utricule length outside its catheter body is manufactured longer, do not need capsule when in use
The position of volume expansion is arranged adapter sleeve.
In order to avoid catheter body scratches tissue, the marginal portion of catheter body of the present invention is rounding
Angle.
The beneficial effects of the invention are as follows：Particle conduit of the present invention sets radioactivity before human body is imported on utricule
Particle, the particle conduit is while nasal feeding or drainage is played, and particle can also play intracavitary irradiation treatment to tumour
Effect.When tumour knurl body disappears, a certain amount of gas or liquid are filled with into utricule, makes balloon inflation, capsule is arranged on
Particle on body is again at, close to the position of tumour, in whole therapeutic process, to be repeatedly inflated utricule
Or topping up, it is ensured that radioactive particle is close to tumour always, allows it to play optimal therapeutic effect.The present invention can be applied widely
In the obstruction occurred in human body by tumour or narrow cavity, such as oesophagus, stomach and intestine, bile duct, ureter, urethra and big vein
In blood vessel, its application prospect is wide, and application value is high.During Case treatment, a conduit only need to be imported, is repeated
Repeatedly utricule is inflated or topping up, after oncotherapy produces a desired effect, utricule can be deflated or tapping after will
Particle conduit takes out, and without Repeated Operation, simplifies therapeutic process, it is ensured that the effect for the treatment of, and its pain is light, and wound is small, disease
People is easier to receive.
