Description

Personalized self-adaptive nasal fixator

Technical Field

The utility model relates to a medical treatment auxiliary assembly technical field, concretely relates to individualized self-adaptation nasal bone fixer.

Background

The nose has the functions of ventilating and beautifying the appearance of the face and is composed of a bracket structure and covered soft tissues. The bracket structure consists of nasal bones, frontal nasal processes, maxillary frontal processes and various nasal cartilages, wherein the nasal bones are upwards connected with the frontal nasal processes, and two sides of the nasal bones are connected with the maxillary frontal processes; the upper end of the combination between the nasal bones is tight, the lower end is slightly separated, and the combination line is superposed with the front median sagittal line. The lower end of the nasal bone is horizontally connected with the lower 2 pieces of lateral nasal cartilage at the infraorbital margin, the lateral nasal cartilage is downwards connected with the 2 pieces of alar nasal cartilage, and a plurality of smaller accessory cartilages are arranged between the lateral nasal cartilage and the 2 pieces of alar nasal cartilage; the nasal septal cartilage (1) is connected to the inferior end of the nasal bone, the ethmoid vertical plate, the plow bone and the edge of the piriform foramen in the anterior median sagittal position. The structural integrity of the nasal cradle is the basis for maintaining the nasal profile (dorsum of the nose, columella, alar, apex and nostrils).

①, after the fracture of the nasal stent (nasal bone and/or nasal cartilage), resetting and fixing are needed, ②, congenital malformation of the nose (such as severe saddlenose), malposition healing after the fracture of the nasal bone or the nasal cartilage, unsatisfied nasal shape, osteotomy, resetting, trimming and fixing are needed for the nose, ③, after deviation correction surgery of nasal septum, the nasal stent fixing is needed, in the post-operation recovery period of the nasal stent, the reshaped nasal stent needs to be fixed properly for 2-4 weeks, which is not only beneficial to the firm healing of the immovable part in the proper position with the surrounding part, but also can protect the relatively fragile injured or post-operation nasal stent part, and treat seepage generated by the wound in the nasal cavity.

Aesthetic and reliable fixation must be achieved by proper fixation of the linkage between the back of the nose and the nasal cavities on both sides, so that both the movable part of the nasal stent can be fixed as a whole and the whole can be fixed at a suitable position on the surrounding immovable part, and therefore, proper fixation between the back of the nose and the nasal cavities on both sides is of great importance for the fixation of the nasal stent.

At present, an ideal fixing tool or an ideal fixing method does not exist clinically, the traditional nasal stent fixing method such as gauze packing, adhesive tape encircling fixing and the like has various defects including ①, most of the nasal stents are not fixed stably enough, the nasal bones and/or cartilages are difficult to be ensured to be continuously in ideal positions, the adhesive tapes are difficult to attach for a long time, gauze cannot have an effective shaping effect and the like, ② cannot protect the relatively fragile nose, ③ cannot properly treat seepage of wounds in the nasal cavity and the like, ④ has the defects that the appearance of the patient is affected and the compliance of the patient is reduced due to more gauzes and adhesive tapes on the face, ⑤ and the packed gauzes and cotton balls can cause the patient to breathe unsmooth, cause pain and easily fall out of the nasal cavity, particularly during sneezing, so the traditional mode is not beneficial to recovery, and also affects the appearance, comfort and ventilation of the patient and seriously affects the compliance.

In order to solve the problems, the utility model discloses a supplementary external fixation device after nasal bone fracture or osteotomy "(CN 206587084U) uses the shaper detachably installed between a pair of backup pads, and utility model discloses a fixing device for nasal bone fracture" (CN207804452U) adjusts the holding strip through 2 handle nipping so as to be fit for patient's size and angle of nasal bone and keep the connecting plate fixed through swivel nut, thereby guarantee that the holding strip can stable clamp on patient's nose, play the fixed action, but all still need the mode of packing in the nasal cavity to support fixedly, pack in the nasal cavity and lack the relation between the back of the nose, it is difficult to fix steadily; the utility model discloses a nasal bone fixation clamp for ENT department "(CN 208447885U) uses 2 inner nose strips and 1 nose bridge fixing plate to fix the nasal bone, and sets up the oxygen passageway in the inner nose strip, though solved the problem of ventilating, but lack the dynamics adjustment of fixing between inner nose strip and nose bridge fixing plate, do not solve the joint fixation problem between the back of the nose and the nasal cavity equally yet; the fixer after the nasal bone reduction (CN205198227U) is fixed with the head only by a nasal cavity plug and a fixing rod at the front end of the nasal cavity plug, lacks the nasal back fixation and also cannot firmly fix the movable nasal bone fracture part. In summary, the problems with the prior art include: unstable fixation, difficult ventilation, poor comfort, low aesthetic degree, short durability and the like. Therefore, the utility model discloses the key solution has nose support's proper fixed, ventilation, comfortable and pleasing to the eye problem, improves fixed effect.
