Description
Technical field
This disclosure relates to medical appliance field, and in particular, to a kind of nasal cavity bracket.
Background technique
Nasal cavity disease is numerous, and therapeutic modality can be divided into two kinds according to whether needing to perform the operation.The disease for wherein needing to perform the operation
Case such as chronic rhinosinusitis coexisting is one of most common disease of hals,Nasen und Ohrenheilkunde, shows according to the data of China's epidemiology,
About 16.3% adult suffers from this disease, and the disease incidence than arthritis and hypertension is taller.Moreover, table on evidence
Bright, nose-nasosinusitis disease incidence has increased trend.Although chronic rhinosinusitis coexisting is not fatal disease, but obviously
The life quality for affecting patient may further result in many functions and sense in addition to the clinical symptoms of known nose plug pain rhinorrhea
Damage in terms of feelings, the influence of damage and chronic hypoxia to cardio-cerebrovascular to downtake etc. is also increasingly by people
Concern.Therefore, the enough attention of clinician should be caused.Functional endoscopic sinus surgery is current treatment conservative therapy
The most important treatment means of invalid chronic rhinosinusitis coexisting.Functional nasal endoscope menisectomy is exactly to remove sinunasal
On the basis of interior lesion, retain the normal configuration and mucous membrane of nasal cavity and nasal sinus to the greatest extent, form good ventilation and draws
Stream promotes the form of sinunasal mucous membrane and physiological function to restore good function.But clinically adhesion of nasal cavity is intranasal
A kind of postoperative relatively common complication of sight glass, causes diseased region air-flow obstructed, and inflammation can not subside, and causes disease multiple again
Hair, brings great pain to patient.
In addition, also for example there is a kind of nasal septum to one or both sides bending or nasal septum one or both sides local protuberance
Illness, which can cause nasal cavity, nasal sinus physiological dysfunctions and generate symptom (such as nasal obstruction, nosebleed, headache) person, claim

Easily-deformable feature, although can not influence the breathing of patient while hemostasis by compression using metallic support, substantially all
It is that several specific models are selective, and can not be adjusted according to the specific nasal cavity size of patient, to cause off size suitable
Caused by feeling of pain, patient comfort is poor.
In addition, treatment concept increasingly tends at present with deepening continuously to nose-nasosinusitis morbidity case Mechanism Study
In the drug therapy regular in the case where guaranteeing adequate drainage, operation bring Accessory injury is avoided, i.e., there is also do not needing
The therapeutic modality of operation.Wherein, the drug therapy regular on the basis of ensureing that sinunasal drains unobstructed using nasal cavity bracket
Gesture is a kind of relatively good mode, and reduces drug and use brought side effect.
In addition, snore disease patient is more and more at present with the improvement of quality of life, maximum harm of snoring is exactly to cause slowly
Property anoxic, increase the burden of cardiovascular and cerebrovascular, slept for a long time cannot adequately rest.The obstruction of nasal cavity is to lead to snoring most
Main obstructive level, increasing for these and refusal operation patient, improves nasal airflow using nasal cavity bracket
Also it loses to be the selection got twice the result with half the effort.
Therefore, industry is badly in need of the novel nasal cavity bracket that a kind of therapeutic effect is good and comfort level is high, stops guaranteeing that filling is oppressed
While blood effect, the malaise symptoms such as headache caused by patient will not be caused to block up because of nose promote the epithelium of bronchia mucosal used
The generation of change and adhesion.
