The beneficial effects of the utility model are that, the plugging device adopts the pear -Shaped design, and its two makes different diameters, divides into major part and microcephaly, and the doctor of being convenient for selects one end of suitable size to carry out the shutoff in the operation, and plugging device orientation is in vivo easily adjusted to the calabash shape, and the doctor of being convenient for selects the most suitable shutoff angle, improves treatment, protruding this plugging device of messenger of the protruding perhaps strip of punctiform produces with the fistula mouth and rubs, has better location effect, it acts as go -between to carry uses when being used for the doctor to take out this plugging device, carries node on acting as go -between the snatching of foreign matter pincers of being convenient for.
Description
Technical field
This utility model belongs to technical field of medical instruments, is specifically related to a kind of bronchial occlusive device.
Background technology
At present, the respiratory system disease such as bronchopleural fistula, refractory pneumothorax just the health of people in serious harm, not only increases the medical expense of patient, extends the hospital stays, once aggravation, can cause death.
Under bronchoscope, intracavity Occlusion therapy is a kind of novel medical procedure being used for the treatment of bronchopleural fistula of development in recent years, and its principle is under bronchoscope, carries out shutoff to bronchopleural fistula drain bronchus, thus reaches the object of closed fistula mouth.
Under bronchoscope, intracavity Occlusion therapy is a kind of effective bronchoscope interventional technique, and patient can be made to avoid accepting video-assisted thoracic syrgery (VATS) or other surgical operations, reduces medical expense, shortens length of patient stay.
Sealing agent and stopper two class can be divided into generally: 1, sealing agent comprises autologous blood+thrombin, Fibrinogen+thrombin, fabric chip and fibrin complex, Polyethylene Glycol etc. for the bronchial method of shutoff.Sealing agent is close with conventional bronchoscope on the impact of blood gas index, and shortcoming is some patients after accepting sealing agent treatment, may there is the possibility of sealing agent self falling, cause Endodontic failure; Stopper mainly comprises Vata and receives shellfish (Watanabe) bronchus plug (silicone material), bronchoscope lung and subtract and hold flap valve, sacculus, turn and cecum stent etc., American scholar Te Lawalin (Travalin) etc. adopt bracket for lung volume reduction treatment refractory pneumothorax, result has the patient of 47.5% to leak gas to stop completely, and 45.0% patient is leaked gas minimizing.The patient of sealing agent Endodontic failure can using stopper as a kind of therapeutic choice.Ductus arteriosus occluder Therapeutic Method is because wide application, and wound is little, and infection rate is little, and post-operative complication is few, and patient recovers fast, and mortality rate is low, the advantage of expense relative moderate and be applied to clinical practice more and more widely.
At present, stopper in Chinese patent mostly is the stopper of net grid support and film combinations, if the patent No. is " CN200720188540.2 ", Authorization Notice No. is " CN201154004Y ", a kind of bronchial occlusive device disclosed in the Chinese utility model patent that name is called " bronchial occlusive device ", comprise a net cylinder be made up of Nitinol tinsel, described net cylinder is a broadside lines is corrugated revolving body, the side of net cylinder and wherein one end of net cylinder cover continuously with pellosil, pellosil and net cylinder tight adhesion, the net cylinder one end being covered with pellosil forms cecum, the other end is opening.But the film portion cracky of this stopper, therapeutic effect is difficult to lastingly, and manufactures complicated, and cost is higher.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides two all can use and is easy to adjust angle, bronchus shutoff plug convenient to remove, in addition, this bronchus shutoff plug manufacture is simple, with low cost, being easy to promote.
For solving the problems of the technologies described above, this utility model provides a kind of bronchial occlusive device, and described stopper is Pear-Shaped, and one of this stopper is major part, and other end is microcephaly, is waist between major part and microcephaly;
Described stopper is provided with lift line, and one end of described lift line is connected to the waist of stopper.Described stopper is large a, other end is the Pear-Shaped of microcephaly, stopper is placed in after in bronchial lumen, can by the direction of the large and small head of adjustment and position, such as by first microcephaly being stretched into a region, forward to after wanted block-up position until major part, described stopper is put in towards major part direction, thus finds optimal shutoff angle.
Preferably, described stopper major part is 3:2 with the diameter ratio of microcephaly.
Preferably, the surface of described stopper is provided with point-like projection.
Preferably, the surface of described stopper is provided with strip projected parts.
Preferably, described stopper is solid construction.
Preferably, described lift line is provided with node.
Preferably, the length of described stopper is 8-20mm, and the diameter of the major part of this stopper is 5-10mm;
The diameter of described spot-like projections is 1-2mm, height 0.5-1mm;
The length of described lift line is 1.5cm.
Described bronchial occlusive device by health public welfare industry scientific research special project (NO.201402024) fund supported research.
The beneficial effects of the utility model are, stopper adopts Pear-Shaped design, its two is made into different diameters, be divided into major part and microcephaly, be convenient to doctor selects one of suitable size to carry out shutoff in operation, gourd shape is easy to adjust the direction of stopper in bronchial lumen, is convenient to doctor and selects optimal shutoff angle, improves therapeutic effect; Protruding or the strip projected parts of point-like makes this stopper and fistula mouth produce to rub, have better locating effect; Lift line is used for using when doctor takes out this stopper, and the node on lift line is convenient to the crawl of lift instrument.This utility model can be made into different size, and the size specification analyzing rear selection applicable according to patient profiles by doctor is treated.
