Abstract
The utility model relates to an inner supporting skeleton for tracheas in a human body. The supporting skeleton is a cylindrical structure formed by wave-shaped nickel titan memory alloy wires from beginning to end, the corner angle of the wave is round arc-shaped, and the wave amplitude of the wave is same. The utility model is especially suitable for the inner supporting skeleton of the soft tissue of the tracheas. The utility model has the advantages of convenient implantation, safety, and evident therapeutic efficacy.
Description
This utility model relates to medical device, the tracheal branches support that provides a kind of human body to use especially.
Along with medical science applied development, interventional therapy is widely used and develops.Because pathological changes causes that human body tube chamber (as trachea, biliary tract, cardiovascular, prostate etc.) stenosis is narrow, even block that patient suffers very big misery, mortality rate is very high.Adopt advanced device and superb operation, put into certain inner support frame (interventional therapy) at lesions position, it is unimpeded that the tube chamber that narrows down is able to, and can alleviate patient's misery, life-saving to a great extent.Interventional therapy in the medical treatment is a subject of rising in recent years, and it has unique effect for those with the insurmountable medical pertinacious disease of conventional treatments, for the misery that alleviates patient, prolongation life important meaning is arranged.Interventional therapy comprises the content of two aspects: the one, and superb treatment means, the one, the implant devices of excellent performance.Be used for the trachea inner support frame in the past, and adopted spiral type or netted more, its function mainly is to produce restoring force at compressive strain, be used to expand tube chamber, but when human body respiration, when cough with asthma produces axial vibration, the bracing frame position is easy to take place play or overlapping, and the restoring force deficiency.
The purpose of this utility model is to provide a kind of inner support frame that is particularly suitable for the trachea soft tissue, and it implants convenient, and safe and reliable, therapeutic effect is remarkable.
This utility model provides a kind of person's windpipe inner support frame, it is characterized in that: this bracing frame is the garden tubular structure that wavy Ultimum Ti silk (1) joins end to end and surrounds.
In addition, the drift angle of wave described in the utility model is preferably the garden arc; The wave amplitude of wave is identical.
The utlity model has following advantage: (1) nitinol alloy wire has elastic performance, and support can stand very large deformation under external force, can recover original form in case external force is eliminated, and permanent deformation does not take place; Meanwhile, in large deformation scope very, its resilience force remains unchanged substantially, thereby makes support very soft, can not produce intensive constriction when patient moves; (2) nitinol alloy wire has excellent biological compatibility, and is corrosion-resistant, wear-resistant, nontoxic to human body, is easy to be become one by the human body soft tissue parcel; (3) support adopts the triangular structure of many groups garden arc drift angle, and Shu Chengyi tuftlet easily flicks after being put into lesions position, has big support force, and can not produce the position play.
By embodiment in detail this utility model is described in detail below in conjunction with accompanying drawing.
Accompanying drawing 1 is a kind of structural representation of this utility model person's windpipe inner support frame.
Accompanying drawing 2 is the another kind of deployed configuration sketch map of this utility model person's windpipe inner support frame.
Embodiment 1
As shown in Figure 1, adopt the super memory alloy wire that plays to make waveform, the shape in each cycle is near triangle, and drift angle is the garden arcuation, and the waveform silk surrounds ring-type thus again, and two ends is connected together.Adopt that this structure can adapt to that person's windpipe is breathed, the vibration during cough with asthma, it is lasting to adopt power that memorial alloy superelastic stents distortion back produces the to close in addition.
Adopt the memory alloy wire material of φ 0.3～0.8mm, make the tracheal branches support of each specification of φ 25 * 15, φ 20 * 15, φ 20 * 10, φ 15 * 10, implant respectively in the Canis familiaris L. trachea by total institute of ground force Pneumology Department, the experimental result of implanting back 30 days, 60 days, 90 days, 100 days shows: this device architecture is reasonable, implant easy, realize supporting the function of tube chamber, had good biocompatibility.
Embodiment 2
As shown in Figure 2, be that with enforcement side 1 difference the waveform of deployed condition is not wait wave amplitude.
Claims (3)
1. person's windpipe inner support frame, it is characterized in that: this bracing frame is the garden tubular structure that wavy Ultimum Ti silk (1) joins end to end and surrounds.
2. according to the described person's windpipe inner support frame of claim 1, it is characterized in that: the drift angle of described wave is the garden arc.
3. according to the described person's windpipe inner support frame of claim 1, it is characterized in that: the wave amplitude of described wave is identical.
