Description
Technical field
This utility model relates to a kind of interventional medical device, relates to a kind of narrow sustainable expanding foley's tube of per nasal remain-type upper digestive tract of optimum upper digestive tract that is specially adapted to specifically.
Background technology
Balloon expanding technology is the novel medical skill with Wicresoft or the alternative traditional surgery of non-invasive methods that the eighties grows up, and can be used for blood vessel or the narrow property of non-blood vessel tract disease.Along with the development of guided Interventional Technique and the improvement of apparatus technology, the balloon expandable plasty is used extensive day by day.
At present, interventional radiology handle that optimum upper digestive tract stenotic lesion can adopt permanent upper digestive tract inner support to insert, provisional upper digestive tract inner support is inserted, simple balloon expandable forming treatment.The optimum upper digestive tract of permanent upper digestive tract inner support placement in the treatment is narrow, can remove narrowly rapidly, recovers normal diet, but complication is many, patient is painful greatly, insert for a long time and cause that support two ends granulation tissue hyperplasia causes the upper digestive tract restenosis.Provisional upper digestive tract inner support inserts that also can to remove upper digestive tract at once narrow, can in support insert 1～12 week the back take out inner support, but still there is upper digestive tract restenosis problem in support during inserting.The simple balloon expandable treatment relapse rate height that adopts, long-term efficacy is very dissatisfied, and is narrow for the intractable upper digestive tract, needs the repeated multiple times dilation therapy, increases operation risk and medical expense, increases medical and nursing work person and patient's dose radiation.Therefore, seek the difficult problem that the narrow method of a kind of comparatively desirable optimum upper digestive tract of radical cure is the clinical position person faced for a long time.
Summary of the invention
The purpose of this utility model provides a kind of per nasal remain-type upper digestive tract sustainable expanding foley's tube at existing weak point in the above-mentioned technology just.This foley's tube is to design according to upper digestive tract dissection and lesion characteristic, and upper digestive tract is narrow to provide a kind of ideal reliable foley's tube in order to treat, and strives reaching anatomy and cures.
The purpose of this utility model can realize by following technique measures:
The sustainable expanding foley's tube of per nasal remain-type upper digestive tract of the present utility model, be installed on the dilating sacculus on the trocar sheath outer wall and be installed on the intraluminal inflation medium transport of trocar sheath conduit, nasal feeding nutritive canal, drainage tube, wherein the front port of inflation medium transport conduit is by the through hole that processes on the trocar sheath tube wall and the intracavity inter-connection of dilating sacculus, and port is connected with the inflating medium source by pipe joint thereafter; The front port of nasal feeding nutritive canal extends to the front end of trocar sheath, and is connected with extraneous (upper digestive tract) by the through hole that processes on the trocar sheath front end tube wall, and port is connected with nasal feeding nutrition supply source thereafter; The front port of drainage tube is connected with extraneous (upper digestive tract) by being positioned at the through hole that processes on the trocar sheath tube wall of dilating sacculus rear portion, and port links to each other with negative suction system by pipe joint thereafter.
Dilating sacculus described in this utility model by before, during and after three sections sacculus constitute, and the wall thickness of its leading portion sacculus is less than the wall thickness of the wall thickness of back segment sacculus, the back segment sacculus wall thickness less than the stage casing sacculus.When in dilating sacculus, inflating (or liquid) by inflation medium transport conduit, leading portion, back segment, interlude successively expand, and (two sections expand earlier perhaps, interlude expands then), external diameter is identical after three sections complete expansions, the length of leading portion, back segment is preferably 1～4cm, and interlude length and sacculus external diameter are decided according to clinical needs.
The trocar sheath at this utility model dilating sacculus two ends is provided with radiopaque gauge point, and trocar sheath back segment outer wall is provided with and is used to observe the scale mark that sacculus inserts the upper digestive tract degree of depth.
Drainage catheter described in this utility model, nasal feeding nutritive canal can adopt a conduit to be connected according to the clinical position needs.
The beneficial effects of the utility model are as follows:
1. have expansion, continue multi-functionals such as support, nasal feeding nutrition, drain.Can either be interrupted or the lasting upper digestive tract narrow section that supports, avoid upper digestive tract narrow section expansion back retraction, nutrition supply during nasal feeding nutritive canal perfusion nutritional solution guarantees the sacculus continuous expansion can aspirate the upper digestive tract endocrine again smoothly and gather, and prevents to suffocate.
2. the function that has the upper digestive tract inner support can continuous expansion, has avoided support to insert for a long time and has caused that the local organization hypertrophy produces problems such as upper digestive tract restenosis, obturation.
3. can prevent the restenosis of simple balloon expandable postangioplasty tube chamber, improve late result, and reach the anatomy healing.
4. the characteristics that have higher-strength and non-expansibility, inflated (liquid) conduit connect Pressure gauge can observe directly the interior pressure state of sacculus.
5. only need the once holding tube operation, reduced the patient suffering, reduced patient's medical expense, operation risk and complication.
6. inserting can be operating under the X line or under the gastroscope, simple to operate, is easy to the location, no wound, and the patient can accept mostly.
