Description
Technical field
The present invention relates to a kind of device of technical field of medical instruments, especially treat the novel adjustable length control formula foley's tube of narrow or inaccessible capable dilation therapy in the esophagus tube chamber.
Background technology
Tube chamber internal shaping art is to treat luminal stenosis or inaccessible invasive Therapeutic Method commonly used at present, has that wound is little, rapid-action, safe and reliable, an operating time and the hospital stays is short, simple operation and other advantages, and clinical practice is extensive.
Foley's tube is the main apparatus of tube chamber internal shaping art, and it is narrow or inaccessible separately or to cooperate support to use in the treatment tube chamber.
Blood vessel and non-lumen of vessels property are narrow in or inaccessible difference such as tube chamber self structure, pathological changes reasons, and be also different to the requirement of required foley's tube.
Esophageal wall contains the flesh layer of multilamellar cross arrangement, and physiological movement is complicated than blood vessel, and also narrow or inaccessible complicacy many than vascular of narrow or inaccessible reason and corresponding performance in the esophageal lumen.
Chemicals corrosivity is narrow to be clinical modal esophagus benign stricture, needs the treatment of repeated multiple times row esophageal lumen intramedullary expansion.Apparatus at present commonly used has the Sha Shi pipe or the foley's tube of different-diameter.Though Sha Shi pipe is inserted and can directly go the dilation therapy of long section and simple, pass in and out the thick convergent divergent channel of diameter repeatedly and make patient's unusual misery when treatment, and mucosa takes place easily tear hemorrhage; Many patients are difficult for cooperating, even refuse or abandon further treatment.Though the diameter when foley's tube can significantly reduce expansion apparatus turnover patient throat alleviates patient's misery.But the sacculus of clinical use generally all is to make before the art, and diameter, length are fixed.When running into long pathological changes, single length of balloon can't guarantee whole section pathological changes of disposable expansion, needs a plurality of sacculus of associating or the single foley's tube of repeated moving.The flesh layer structure of esophagus makes sacculus remove the back esophageal wall has retraction in various degree.When using a plurality of sacculus at the same time or move using single sacculus, some part that whole pathological changes may take place does not obtain expansion, the asynchronous of different parts expansion perhaps occur, occurs the lacerated wound of mucosa easily and digestive tract hemorrhage takes place.All need constantly again X line location down simultaneously in the art; Increase the operating procedure of operation and prolonged the operating time; The X line that has increased medical personnel and patient exposes to the open air, also increases the probability of postoperative complication, and repetitive operation also can increase patient's physiology, psychological burden thus repeatedly in addition.
The pernicious esophagostenosis that the progressive stage esophageal carcinoma of long section is caused or inaccessible clinical also more common; Single foley's tube is disposable can't be to the synchronous dilation therapy of whole pathological changes; Tumor tissues is more crisp in addition; Blood supply is abundant, and digestive tract hemorrhage takes place when utilizing a plurality of sacculus or single sacculus to move dilation therapy more easily.
Said method all can't guarantee the curative effect of narrow or inaccessible capable dilation therapy in the long section esophageal lumen, also may tear because of the asynchronous inner membrance/mucosa that causes of expansion, and it is easy to increase postoperative complication such as hemorrhage.And repeated moving is perhaps changed foley's tube and X line location down in the art, has increased the complexity of operation and has prolonged the operating time, and the X line that has also increased medical personnel and patient exposes to the open air; And may increase operative treatment cost and post-processed complication and the wholistic therapy cost that causes increases.And the increase of operation complexity and the prolongation of operating time also possibly increase patient's physiology, psychological burden.
Once insert a ball ductus bursae and can carry out the dilation therapy of different length, running into the long section that surpasses former sacculus length when narrow or inaccessible, the external diameter in the time of can reducing conduit turnover patient bottleneck throat alleviates less patient suffering, reduces wound.Also can directly prolong length of balloon, simplify the operation, reduce the postoperative complication risk, reduce medical expense and alleviate patient's mental burden and misery.
In the research that early stage, the scholar carried out, some directly capable multisection type sacculus is directly expanded, and some places the outer external mobile device of balloon cavity to change actual full length of balloon through adjustment in advance; But above-mentioned design and method or when guaranteeing overall expansion length, but can't guarantee the synchronicity of whole pathological changes expansion; It is long the full partial-length of sacculus maybe can to occur; Increase foley's tube structural complexity and manufacturing process requirement greatly, increased instrument failure incidence rate in cost of manufacture and the art.
