Abstract
The utility model discloses a medical supporting frame used for the lumen of a human body, which comprises a mesh type circular-tube-shaped main body, and a head end and a tail end parts of a special tube of which the diameter is larger than the main body. The supporting frame is sectional type structure; flexible connecting threads are respectively arranged between the adjacent sections. The tube wall of the supporting frame is coated with a thin film. The supporting frame is easy to adapt to the bend and the deflection of the lumen body, has no stress to generate and has the advantages of good whole applicable performance.
Description
Technical field
This utility model relates to a kind of medical stand that is used for body lumen, particularly a kind of medical stand that is applicable to esophageal stricture or obstruction.
Background technology
At present,, except the excision treatment of undergoing surgery, also adopt at diseased region and implant tubular support, the esophagus of patient's pathological changes is strutted, food can be passed through for esophageal stricture that causes because of reasons such as tumor, cicatricial contracturies or obstruction.This support is a netted overlay film tubular, forms with metal wire knitted, and it is netted that sidewall is, flexible expansive force.
Food often made support to bottom offset to the impact of support and the wriggling of esophagus when patient took food.For preventing displacement, the product that has is that " the thin body of thick head "---first, terminal part is the pipe of slightly larger in diameter with support Design.
The pattern of " go up and also move under moving " when this all-in-one-piece tubular support passes through with the esophagus wriggling at food, it is bad that cradle wall and esophageal wall are fitted, by the head of slightly larger in diameter, the displacement that terminal part also is not enough to stop support.Moreover support head, the pipe wall that the terminal part diameter is bigger are that face contacts with patient's esophageal wall, the compressing of patient's esophagus are stimulated make patient that uncomfortable sensation be arranged; The monolithic construction support can produce recovery stress to esophageal wall in the esophagus of bending, influence the blood circulation of esophageal wall, makes esophageal wall atrophy even necrosis.
The utility model content
Technical problem to be solved in the utility model provides a kind of medical stand, and it is little to the esophageal wall compressing easily in the implant patient esophagus, is not easy to be subjected to displacement.
This utility model medical stand still is a netty circular tube shape totally, but is the segmental pattern structure, and head end portion and terminal part respectively are a joint.Support totally is 3～10 joints, and the length of every joint is 10～20mm.Each sections can be isometric, also can be not isometric.
Each is made each sections of this utility model medical stand by one metal wire braiding, and the grid of braiding is a rhombus, and its vertical angles α is 60 °～90 °.
Connect with flexible filaments between each adjacent segments.First, terminal part diameter is greater than the diameter of main part sections.Special pipe preferred class first, terminal part is seemingly spherical.The netted tube wall of tubular support is covered with thin film.
This utility model medical stand is established connecting filament owing to adopt the movable connection of more piece overlay film between adjacent segments, when food by the time support each save independent stress deformation, and make it produce the distortion of complying with up and down, be similar to the wriggling of esophagus.One joint of support is during amoeboid movement, do not influence or influences fitting tightly of other sections and esophageal wall very less, makes support have the flexural deformation of easy adaptation cavity and do not have the stress generation of axially bootstrapping straight.Can also set the length of each sections of support according to the needs of each patient's pathological changes different parts, the different state of an illness.
Head end portion, the netted special-shaped pipeline section of terminal part are designed to similar sphere, make that itself and contacting of cavity are that sphere contacts but not plane contact.The time spent of doing that makes head, terminal part be subjected to longitudinal force when patient's feed is a little less than the pressure pinprick.Similar spherical structure also makes edge diameter when stressed of its end be easy to become big, and the adhesive force of increase and esophageal wall reduces displacement and slippage.
In a word, this utility model medical stand is rational in infrastructure, and is fixing reliable, and little to the cavity wall stimulation, whole applicable performance is good.
Description of drawings
Fig. 1 is this utility model medical stand structural representation.
The represented parts of number in the figure are 1-head end portion; 2-rack body part; The 3-connecting filament; The 4-terminal part; The 5-mesh.
The specific embodiment
Figure 1 shows that an embodiment of the present utility model.The present embodiment medical stand is made up of five sections, and wherein main part 2 is 3 joints, and head end portion 1 and terminal part 4 respectively are a joint.The length of every joint is selected in 10～20mm scope, and this routine head end sections 1 is longer than end sections 4.Every joint is made by one metal wire braiding, has diamond-shaped meshes 5, and rhombohedral vertical angles α is 60 °～90 °.Head end portion 1 and terminal part 4 be designed to similar sphere.
During manufacturing, the TiNi titanium-nickel wire of selecting suitable diameter for use by standard respectively on particular manufacturing craft braiding form each sections, connect adjacent two joints with connecting filament 3 then.Connecting filament 3 can be selected nylon or other flexible filaments that is suitable for for use.Afterwards on support by the kiss-coating film, form to cover the elastic thin-wall of all mesh.
