Abstract
The utility model discloses a bracket for bronchial dead ends, and pertains to a device closing bronchial cut or keeping cut closed. The utility model comprises a cylindraceous gridded bracket made by memory alloy and a leather coat made of polyurethanes combining with the bracket. One side of the bracket is opened, while the leather coat of the other side extends to be a closed spherical dead end. After the utility model is sent to the closing end of bronchial stump fistula by airway sending device, the bronchial fistula is jammed. The thorax is isolated from air, and then drainage of empyema is operated, patients will be cured. The utility model has the advantages of simple structure and is easy to use, which thus resolves the treatment problem of bronchial stump fistula, alleviates pain of patients, and thus saves a large amount of hospitalization costs.
Description
Technical field
This utility model relates to the device that is used for closed bronchus wound or keeps wound closure, specifically is a kind of bronchus cecum support.
Background technology
Implement the lobectomy of lungs postoperative at thoracic surgery, the bronchus stump fistula that causes owing to the infectious pathological changes of bronchus stump or suture defects is one of reason that forms empyema.Generally need carry out surgical operation therapy once more, the excision rib is finished the limitation thoracoplasty, will use 3-6 month treatment time usually, and the success rate of not only mending fistula is low, cause suffering to patient, and medical expense has increased patient's burden.
State's pencil tool (standard) word 2002 discloses a kind of NiTi memorial alloy expanding endotracheal stent for No. 3460080, and is cylindrical or the double horn mouth is cylindrical, and these support two ends are little circular arc, can not damage tracheal wall.Be placed on the narrow inner surface of trachea through the inner support of delivery device, return to original state immediately, make narrow positions recover unobstructed soft state.The expanding endotracheal stent is applied in tracheal stenosis due to pulmonary carcinoma late period more at large, and vertical diaphragm and esophageal neoplasm cause in the tube chamber external pressure narrow treatment.
Chinese patent 2391571 discloses a kind of " bronchial stent inserter ", its primary structure is by push-pull bar, trocar sheath, trocar sheath handle, Ultimum Ti expandable stent constitute, the left part of trocar sheath handle stationary pipes, push-and-pull runs through state's trocar sheath handle and is arranged among the trocar sheath, and the Ultimum Ti expandable stent is arranged between trocar sheath and the push-and-pull pipe right part.Oxygen inlet and medicine inlet are set on the bronchial stent trocar sheath handle, when inserting the Ultimum Ti expandable stent, cure by oxygen therapy and drug treatment.
Summary of the invention
This utility model be exactly for the therapeutic effect that solves bronchus stump fistula poor, the medical expense height, the problem of patient's misery, and a kind of satisfied therapeutic effect that obtains is provided is avoided patient's misery of performing the operation once more, the bronchus cecum support that medical expense is cheap.
This utility model is realized by following technical scheme.
A kind of bronchus cecum support comprises after the molding for cylindric memorial alloy grid support and forms the polyurethane overlay film of one; This support one end is open, and the overlay film of the other end extends to form airtight cecum.
This utility model can soften in frozen water 0-10 ℃, during use this utility model being inserted behind the trocar sheath room temperature with contraction state places standby more than 5 minutes, deliver to the bronchial fistula position under the guiding of leader (epitheca pipe) with apparatus for displaying under navigation system monitors at guide wire, the this utility model that will be in contraction state is then inserted the epitheca pipe, use pusher it is pushed into epitheca pipe far-end, the fixing pusher epitheca pipe of dropping back simultaneously, this utility model then can tentatively discharge from expanding and being fixed in the bronchial fistula position, this utility model further resiles under the body temperature effect and forms bigger side tension, stop up the bronchus fistula, make air and chest residual cavity isolated, capable again empyema (residual cavity) external drainage art is cured patient after having removed infection reason.
She Ji this utility model is simple in structure like this, and is easy to use, solved the treatment difficult problem of bronchus stump fistula, alleviates patient's misery, saved a large amount of medical expenses.

The specific embodiment
Below in conjunction with drawings and Examples this utility model is elaborated.
A kind of bronchus cecum support comprises after the molding of self expandable formula for cylindric memorial alloy grid support 2 and forms the polyurethane overlay film 3 of one; This rack body 1a one end is open, and the liner overlay film of the other end extends to form airtight cecum.
Described bronchus cecum support, the overlay film of its other end extends to form airtight sphere cecum 4.
Described bronchus cecum support, the overlay film 3 of its other end extends to form airtight plane cecum 7.
Described bronchus cecum support, the overlay film 3 of its other end extends to form airtight cone cecum 5.
Described bronchus cecum support, the overlay film 3 of its other end extends to form airtight round platform cecum 6.
Described bronchus cecum support, the overlay film 3 of its other end extend to form airtight concave arc cecum (not shown).
The material that this utility model adopts is that the Ultimum Ti monofilament is woven into latticed cylinder, during making the latticed cylinder of Nitinol is flooded in polyurethane is stuck with paste together with the mould that the sphere termination is arranged, and is dried into overlay film.
The termination of mould can also be a flat shape, or the cone shape, or round table-like, or concave arc shape.
This utility model can be processed into specifications such as various different-diameters and length according to clinical needs, to adapt to the filling needs of bronchus stump fistula.As Φ 16mm * 30-60mm; Φ 18mm * 30-60mm.
This utility model sample has obtained satisfied clinical application effect through clinical use.
