Abstract

In order to solve the problem of the existing nose-alveolar ridge anaplasty and nose anaplasty, the invention provides a woven type nickel-titanium alloy nose support frame, which comprises a nickel-titanium alloy wire (1), a silicon rubber film (2) and a connecting support frame (3), wherein the nickel-titanium alloy wire (1) is woven into spiral reticular nose support frames (4), the silicon rubber film (2) covers the nose support frames, the nose support frames (4) arranged at the two sides are connected through the connecting support frame (3), the connecting support frame (3) uses the nickel-titanium alloy wire (1) as a framework, and the silicon rubber film (2) covers the connecting support frame (3). The nose support frame has the advantages that the weaving technology is utilized, different geometrical parameters and weaving parameters are changed, corresponding self expansion capability is obtained, the personalized nose support frame is realized, and the correction goal of a patient is achieved; the appearance is thinner, the weight is lighter, the breathing movement of the patient cannot be influenced, in addition, the support force can be conveniently and flexibly changed, and the orthopedic effect is reached.

Description

Weaving type Nitinol nose stretcher

Technical field

The present invention relates to a kind of nose stretcher, the Weaving type Nitinol nose stretcher after relating in particular to a kind of nose plastic operation and after Patients with Cleft Lip and Palate nasal prosthesis, belongs to cosmetology field.

Background technology

Congenital harelip is that parent phenolics is subject to various factors, causes the rear upper lip of infant birth, palatine to split, and concurrent nose deformity, comprises that the wing of nose subsides, nose pillar deflection.Common restorative procedure comprises nose-alveolar ridge anaplasty and the nose plastic operation before harelip operation.

In order to consolidate the effect of nose-alveolar ridge plastic operation in early stage, the side that simultaneously the supplies a gap wing of nose grows the deficiency lagging behind, after harelip operation, often need patient to wear and use silicone rubber nose support, be placed in Ipsilateral nostril, raise the wing of nose, correct the deflection of nose pillar, but have a lot of problems: 1. nose support is very thick, affect patient's breathing, sense of discomfort is very strong; 2. the strength that nose support produces belongs to passive character, and the too small effect that do not reach, easily comes off, and excessively can not insert, and even causes ulceration, the necrosis of wing of nose mucosa; 3. along with the progress of growth promoter and treatment, need to continue to change the nose support of different model, patient's Family needs is paid more expense and energy; 4. nose plastic operation can solve the nose deformity of some patients were, substantially stops just carrying out afterwards but need to wait until that patient grows, and at waiting time, due to nose teratogenic effect patient's image, can cause irremediable impact to patients ' psychological; 5. operation belongs to derogatory behaviour, also has other uncertain side effect, and as infection, cicatrix, operation accident etc., patient and Family needs thereof are born more spirit and financial burden.At this moment need to adopt better method to overcome the deficiency of prior art means and the problem of existence.Can take in from aspects such as the selection of nose support material and making.

For these problems, there is at present many research, Nitinol has higher corrosion resistance, avirulence than rustless steel, cell attachment is good in animal body, to it, around muscular tissue or nervous tissue are without obvious stimulation and inflammatory reaction, and in body, nickel content is without obvious increase, and peripheral cell is without canceration, there is good histocompatibility and have light weight, the characteristic such as magnetic is faint, intensity is higher, endurance, be conducive to continue performance function in human body.Nitinol has been designed to wide variety of shapes memory for clinical, as fracture interior fixing, spinal surgery, orthopedics, department of obstetrics and gynecology and cranio-facial surgery etc., also developed into medical stent simultaneously, be used for the treatment of trachea, esophagus and urethral stricture and angiemphraxis etc., medically having a extensive future.

Summary of the invention

The object of the invention is:

The problem existing in order to overcome existing nose-alveolar ridge anaplasty and rhinoplasty, the invention provides a kind of nose stretcher of the different size that adopts nitinol alloy wire making, this nose stretcher is not only thinner, lighter, can not affect patient's respiratory movement, and can change easily and flexibly support force, reach orthopedic effect.

Object of the present invention can realize by following technical scheme:

A kind of Weaving type Nitinol nose stretcher, has comprised nitinol alloy wire, silicone rubber membrane, connection bracket, and described nitinol alloy wire is woven into the nose stretcher of spiral net-shaped, and nose stretcher is covered with silicone rubber membrane, and both sides nose stretcher connects by connection bracket.

Described connection bracket, take nitinol alloy wire as skeleton, is covered with silicone rubber membrane.

Beneficial effect of the present invention is:

Weaving type Nitinol nose stretcher of the present invention adopts silicone rubber coating, has good biocompatibility, avoids the stimulation to nasal mucosa and causes anaphylaxis; Weaving type Nitinol nose stretcher is thinner, lighter than silicone rubber nose support, can not affect patient's respiratory movement; After the compression of Weaving type Nitinol nose stretcher, be positioned in nostril, due to rebound effect, can be initiatively afterburning to the wing of nose, and strength is soft lasting, can obtain better orthopedic effect.

Accompanying drawing explanation

Fig. 1 is one of structural representation of the present invention.

Fig. 2 is two of structural representation of the present invention.

Wherein:

1, nitinol alloy wire; 2, silicone rubber membrane; 3, connection bracket; 4, nose support.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the invention will be further described

Weaving type Nitinol nose stretcher of the present invention, nitinol alloy wire 1, silicone rubber membrane 2, connection bracket 3 are comprised, described nitinol alloy wire 1 is woven into the nose stretcher 4 of spiral net-shaped, then utilize solution dipping process, make nose stretcher 4 be coated with silicone rubber membrane 2, silicone rubber membrane 2 preferred thickness 0.1mm left and right.

To for nose plastic operation, both sides nose stretcher 4 adopts take nitinol alloy wire 1 as skeleton, and the connection bracket 3 that is coated with silicone rubber membrane 2 connects.

Design, the producing principle of Weaving type Nitinol nose stretcher of the present invention are: utilize laser scanner technique, existing silicone rubber nose support is scanned, make the digital model of different size.Utilize knitting skill, nitinol alloy wire 1 is woven and forms spiral net-shaped support, form the nose stretcher 4 of different model by changing the geometric parameters such as string diameter, a braided wires number, stent diameter, pitch, and coating silicon rubber coating 2.Make the supporting connection bracket that is coated with silicone rubber membrane 23.For unilateral lip and palate cleft patient, combining laser scanning technology, can, by the nostril profile three-dimensional reconstruction of healthy side, utilize image feature, rebuilds the nostril profile of defect side, makes accordingly personalized Weaving type Nitinol nose stretcher.Utilize material properties completely, by the self-expanding ability of support, realization is repaired position to patient and is supported and expand, thereby completes patient's rectification object.

The present invention has been improved to defect of the prior art, changed silicone rubber nose support thick, affect patient respiratory lamp series of problems, and be easy to processing, need to customize different supports according to different patients, also can reduce production costs, easy to use, easy to implement.

Although here describes and illustrate the present invention by certain or some particular arrangement, but its object do not lie in the described details of restriction, because may have various modifications and structure modify in patent claimed range, does not depart from invention spirit.

The present invention relates to part all the prior art that maybe can adopt same as the prior art realized.
