Description

Nasal cavity foley's tube fixes device

Technical field

The utility model relates to the fixed devices of technical field of medical treatment mechanical, especially nasal cavity foley's tube.

Background technique

The treatment of chronic nasosinusitis can choose drug therapy.But drug therapy can not solve the exception of anatomical structure, Drug itself there are side effect and also about 30% patient it is insensitive to drug therapy.Therefore another option for the treatment of is hand Art treatment.The purpose of operative treatment is to correct the ventilation that anatomical structure is abnormal, irreversible lesion, improvement nasal sinus are cleared up in excision to draw Stream is drained with the ventilation for restoring nasal sinus, so that nasal sinus bronchia mucosal removes the normal performance of function.

Functional Transnasal endoscopy operation is clinically praised highly at present, is operation after all although endoscopic surgery is very minimally invasive Excision, doctor will cut off the tissue of the sinunasal of inequality according to state of an illness difference.To prevent postoperative hemorrhage, to carry out close Nasal packing, therefore, Functional endoscopic sinus surgery still has certain wound, and patient suffering is relatively large.

2004, the engineer of U.S. Silicon Valley was treated the inspiration of the principle of coronary artery hemadostewnosis by interposing catheter, resonable On the basis of solving nasosinusitis pathogenesis, the concept of nasal sinus balloon dilatation is introduced.

Foley's tube instrument includes 0,70,110 degree of nasal sinus guide wire；Guide wire handle；Nasal sinus seal wire and nasal sinus gas Ductus bursae.When operation, first by nasal sinus sacculus it is careful be inserted into guiding catheter, then seal wire is pushed into nasal sinus foley's tube Guidewire port.According to the state of an illness of different nasal sinus, sinus is built into seal wire, and by shining, confirmation reaches purpose nasal sinus.Sacculus is placed in Dou Kou.After location confirmation, pressurization maintains tens of seconds, can be according to circumstances repeated multiple times.

In the course of surgery, since the position of air bag has to the position for being placed in nasal sinus Dou Kou, otherwise operation is not achieved pre- The effect of phase, in surgical procedure, there are many human factor, and most important is exactly the shaking of patient and the shake of doctor, so that air bag It is easy to be detached from the position of nasal sinus Dou Kou.

For this purpose, the utility model provides a kind of fixed device of nasal cavity foley's tube to fix drainage tube, further such that gas Capsule can accurately reach the position nasal sinus Dou Kou.

Utility model content

For above situation, for the defect for overcoming the prior art, the utility model provides the fixed dress of nasal cavity foley's tube It sets, air bag is easily separated from nasal sinus Dou Kou so that surgical effect is bad in the existing nasal sinus balloon dilatation of effective solution Problem.

Its technical solution solved is, including horizontal positioned plate, have on the upper surface of plate left end two pieces it is vertical vertical Plate, two pieces of vertical plates front and backs are symmetrically placed, have interval between two pieces of vertical plates, have arc panel, arc in the interval between two pieces of vertical plates The rear and front end of plate is higher than intermediate position, is hinged with vertical stringer board on arc panel rear and front end；L is hinged on the inside of every piece of vertical plate Shape bar, the corner of L shape bar and vertical plate are hinged, and one end of L shape bar and the outside face contact of stringer board, the other end of L shape bar are in The lower section of arc panel, arc panel lower end is hinged with cuts with scissors with the one-to-one connecting rod of L shape bar, connecting rod lower end and L shape bar lower end It connects, constitutes arc panel and move downward through connecting rod promotion L shape bar rotation so that the shape bar upper end L compressing stringer board is drawn close to centre Structure；There are two the through-holes communicated up and down for plate right end, and two through-holes front and backs are symmetrical, and plate right end has what Open Side Down Two through-holes are inserted at U-shaped bar, the both ends of U-shaped bar respectively, there is the sliding panel that can be slided along U-board, sliding panel upper end folder on U-shaped bar Tight block, gripping block and sliding panel are connected through flexural pivot, there is mobilizable pressing plate in gripping block.

The utility model clever structure, it is novel, nasal sinus balloon dilatation success rate of operation is effectively raised, is saved The amount of labour of doctor, while decreasing the pain of patient, it is easy to spread, it is practical.
