Description

Nose teeth groove mould patterning apparatus
Technical field
This utility model relates to medical orthopedic instruments technical field, particularly relates to a kind of nose teeth groove mould patterning apparatus.
Background technology
Congenital harelip is the modal congenital malformation of a kind of oromaxillo-facial region, and principal character has: upper lip, alveolar process and palatine crack, the wing of nose subsides, nose pillar deflection and shortening, has a strong impact on patient's appearance.
In the prosthesis of I phase chapped lip, obtain offside and lip and nose profile attractive in appearance is exactly surgical ideal all the time, but the wing of nose of too roomy lip soft tissue crack, alveolar process crack, extremely distortion and the little rod structure of nose all are difficult to obtain desirable effect so that rely on merely surgical operation.General, adopting non-surgical technic that the deformity of lip, alveolar process, nose is rescued before the art can help the surgeon to create good surgical condition, make I stage operation effect reach optimization, common, be that two rip-panels of chapped lip tractive of going ahead of the rest is orthopedic in the medical science shaping, treat that tension force descends, so that perform the operation contraction to a certain degree after again in lip crack, alveolar process crack, operating difficulty is descended, and the aesthetic measure of surgical repair is better.
In advance, as in nineteen eighty-three, the report such as Nordin corrects deviation of nasal septum before with inverted T-shaped traction (T-traction) device Rhizoma Atractylodis Macrocephalae and the jaw bow is uncomfortable; And for example, Grayson in 1993 has developed nose and alveolar process moulding (Nasoalvelar Molding, NAM) device; And create ancient Chinese name for Venus method in Taiwan.More than three kinds of methods all use with art prenasal, lip, the alveolus of chapped lip infant moulding, for operator is created good anatomical condition, in the hope of reaching the postoperative effect optimization.
At present, the NAM device of extensive use is in the world realized before the art of chapped lip infant just abnormally, can effectively dwindle lip crack, alveolar process crack, improves wing of nose profile, increases nose pillar height, for the prosthesis of I phase chapped lip provides preferably condition.This NAM device is with the glutinous infant oral cavity that is attached to of palate holder, extend steel wire to the Ipsilateral nostril by the lip crack, form the nose support with self curing plastic, realize closing the purpose of crack and nostril shaping by the height of continuous reconditioning base and the support of adjustment nose, wherein, the intraoral base part critical piece of device for this reason.
Yet have in practice some problems: this NAM device is not only made complexity, time and effort consuming, and manufacturing process both need have department of stomatology professional skill, also need there be first aid team to cooperate, with emergencies such as anti-error suction mistake pharynxs, has obstructing airway to cause the possibility of life danger; There is mechanical stimulus in this device to oral mucosa after wearing, and forms easily pressure ulcer, comes off easily, easily fungal infection in the oral cavity; Infant is worn rear inconvenient suck feeding bottle, and the laundering period needs a few days, and noise is cryed, and family members are distressed, cause giving up halfway; Need frequent further consultation, adjust mouthful interior base and nose support, not only take medical resource, also make infant and head of a family's long drive.Therefore the NAM device is not yet popularized in China's scope, causes chapped lip overall operation effect uneven, has a strong impact on the physical and mental health of infant.
