Abstract
The utility model relates to a dilatation catheter for an ostium of maxillary sinus. The dilatation catheter comprises a tubular dilatation catheter body, wherein a fixed part is respectively arranged at both ends of the dilatation catheter body. The fixed parts are fixedly connected with the dilatation catheter body to form a trapezium, wherein the length of the trapezoid base is larger than the external diameter of the dilatation catheter body. A plurality of drainage holes used for facilitating drainage are arranged on the dilatation catheter body. During chronic maxillary sinusitis operations, the dilatation catheter is placed in the ostium of maxillary sinus after the removal of lesions at the maxillary sinus, so that the maxillary sinus postoperative recovery can be facilitated, the recurrence caused by ostium of maxillary sinus obturation can be effectively prevented and thorough treatment is achieved.
Description
Technical field
This utility model relates to a kind of convergent divergent channel, is applicable to the auxiliary treatment chronic maxillary sinusitis, specifically, relates to a kind of apertura maxillaris convergent divergent channel for apertura maxillaris postoperative sealing patient, belongs to medical instruments field.
Background technology
Chronic maxillary sinusitis is a kind of commonly encountered diseases, at present, in the operation for the treatment of chronic maxillary sinusitis, enlarges apertura maxillaris and removes maxillary sinus lesions, and postoperative patient recovers voluntarily.
In realizing process of the present invention, the inventor finds to exist at least in the prior art following problem, the sealing of part patient's the convalescence after Miles operation apertura maxillaris; the pathological changes recurrence, needs again operation, this part patient still easily sealing of rear apertura maxillaris of again performing the operation; cause the pathological changes recurrence, be difficult to radical cure.
The utility model content
The technical problems to be solved in the utility model is for above deficiency, a kind of apertura maxillaris convergent divergent channel is provided, overcome the defective that part patient pathological changes easily recurs, is difficult to effect a radical cure in the prior art, adopt convergent divergent channel of the present utility model after, have the advantage of thorough treatment.
For solving above technical problem, this utility model is by the following technical solutions: a kind of apertura maxillaris convergent divergent channel, it is characterized in that: described convergent divergent channel comprises the convergent divergent channel body of tubular, and the two ends of convergent divergent channel body are respectively equipped with fixed part, and the two ends of fixed part are fixedly connected with the convergent divergent channel body respectively;
The widest part that described fixed part encloses is greater than the external diameter of convergent divergent channel body;
Described convergent divergent channel body is provided with several conduction holes.
A kind of prioritization scheme, the external diameter of described convergent divergent channel body are 9mm～11mm, and the internal diameter of convergent divergent channel body is 6mm～8mm, and the length of convergent divergent channel body is 9mm～11mm.
Another kind of prioritization scheme, the diameter of described fixed part is 1.5mm～2.5mm.
Another prioritization scheme, described fixed part forms the trapezoidal shape of go to the bottom length of side 18mm～22mm, high 9mm～11mm.
After this utility model adopts above technical scheme, compared with prior art, have the following advantages: convergent divergent channel body two ends are respectively equipped with fixed part, fixed part and convergent divergent channel body are fixedly connected to form trapezoidal greater than this body diameter of convergent divergent channel of bottom length, the convergent divergent channel body is provided with several conduction holes of being convenient to drain, in the operation process for the treatment of chronic maxillary sinusitis, after removing maxillary sinus lesions convergent divergent channel is put into sinus highmori mouth place, be conducive to the apertura maxillaris post-operative recovery, can effectively prevent the pathological changes recurrence that the sealing of postoperative apertura maxillaris causes, thorough treatment.
Below in conjunction with drawings and Examples this utility model is elaborated.
Description of drawings
Accompanying drawing 1 is the structural representation of convergent divergent channel among this utility model embodiment;
Among the figure:
1-convergent divergent channel body, 2-fixed part, 3-conduction hole.
The specific embodiment
Embodiment, as shown in Figure 1, a kind of apertura maxillaris convergent divergent channel, the convergent divergent channel body 1 that comprises tubular, the two ends of convergent divergent channel body 1 are respectively equipped with fixed part 2, and the two ends of fixed part 2 are fixedly connected with convergent divergent channel body 1 respectively, in order to prevent that convergent divergent channel body 1 is at apertura maxillaris place double swerve, the widest part that fixed part 2 encloses is greater than the external diameter of convergent divergent channel body 1, and convergent divergent channel body 1 is provided with several conduction holes of being convenient to drain 3.
Convergent divergent channel body 1 and fixed part 2 all adopt silica gel materials, the external diameter of convergent divergent channel body 1 is 9mm～11mm, the internal diameter of convergent divergent channel body 1 is 6mm～8mm, the length of convergent divergent channel body 1 is 9mm～11mm, the diameter of fixed part 2 is 1.5mm～2.5mm, fixed part 2 forms the length of side 18mm～22mm that goes to the bottom, the trapezoidal shape of high 9mm～11mm, the external diameter of convergent divergent channel body 1 is 10mm in the present embodiment, the internal diameter of convergent divergent channel body 1 is 7mm, the length of convergent divergent channel body 1 is 10mm, the diameter of fixed part 2 is 2mm, and fixed part 2 forms the length of side 20mm that goes to the bottom, the trapezoidal shape of high 10mm.
In the operation process for the treatment of chronic maxillary sinusitis, remove and convergent divergent channel is put into sinus highmori mouth place after the maxillary sinus lesions, place and recovered voluntarily rear taking-up to apertura maxillaris in 3 months and get final product, easy to use, can effectively prevent the pathological changes recurrence that the sealing of postoperative apertura maxillaris causes, thorough treatment.
The above is giving an example of this utility model preferred forms, and the part of wherein not addressing in detail is those of ordinary skills' common practise.Protection domain of the present utility model is as the criterion with the content of claim, and any equivalent transformation that carries out based on technology enlightenment of the present utility model is also within protection domain of the present utility model.
