Abstract
Disclosed is a support network medically treating human body cavities, which belongs to a medical treatment apparatus and especially adapts to be as a support network by positioned into cavitary ducts of patients such as the esophagus, pylori, the cardia, respiratory tracts, bile ducts and urethras through a special inserting device in order to dilating human body cavities. The support network is intertwined right or left by more than one nickel-titanium shape-memory alloy meshes with isotopes; particle-shaped isotopes are bound on the support network; a left or right twined thread of the support network is the nickel-titanium shape-memory alloy mesh, and a right or left twined thread is a plastic pipe with isotope particle inside. The device has the advantages of expanding human body cavities and treating diseases.
Description
Technical field
This utility model relates to a kind of drug effect human body lumen bearing reticular tube, belong to medical apparatus, especially be applicable to by special-purpose inserter and insert the tract bearing reticular tube that patient's esophagus, cardia, pylorus, respiratory tract and bile duct, urethra inside reach the effect of expansion human body lumen.
Background technology
Body cavities: esophagus, pylorus, cardia, respiratory tract and bile duct, the patient of the optimum or malignant stricture of urethra inserts memorial alloy network expansion inner support in wherein, reach the illness of removing or delaying patient, the present utility model people has made detailed description to technique scheme in Chinese utility model patent CN2280525Y " in the lumen multiple film coating bearing reticular tube " and CN230277Y " cardia with lumen in answer film coating bearing reticular tube " two patents, obviously, only be to expand the human body lumen and delay illness or satisfactory inadequately, this utility model is further improving and development of above-mentioned two patents.
Summary of the invention
The technical problems to be solved in the utility model is the above-mentioned weak point that overcomes prior art, can expand the drug effect body cavities bearing reticular tube that the human body lumen has therapeutical effect and provide a kind of.
The technical problems to be solved in the utility model realizes by following technical proposal.
The utlity model has three technical schemes, include and carefully knit silk by a left side and right Ultimum Ti and knit smooth cylindric support grid by the left and right helical trajectory spiral prismatic grid, upper/lower terminal that braiding forms that intersect successively, technical scheme 1, this cylindric bearing reticular tube is intersected woollen yarn knitting and is formed by have an isotopic left side or the right Ultimum Ti silk more than.
This utility model compared with prior art has following advantage: this utility model utilizes the super-elasticity of nitinol alloy wire, to insert narrow human body lumen after its compression, then that lumen is opened is wide for self expandable, simultaneously, supports and has isotope on the rack disease is treated.
Description of drawings
Fig. 1 is this utility model structural representation.
Fig. 2 is the vertical view of Fig. 1.
The specific embodiment
This utility model includes by a left side and right Ultimum Ti filament 1 woollen yarn knitting silk and knits the smooth cylindric bearing reticular tube 3 of closing in by left and right helical trajectory spiral prismatic grid 2, the upper/lower terminal that braiding forms that intersect successively.
Embodiment 1, and cylindric bearing reticular tube 3 is intersected woollen yarn knitting and formed by an isotopic left side or the right Ultimum Ti filament 4 that have more than.
Claims (3)
