The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, described I type sectional shelf-unit and a straight tube support equipped form II type sectional shelf-unit.
The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, described II type sectional shelf-unit is made the integral support of a bifurcated, i.e. III type integral support.
The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, the protrusion place perforate that two bare brackets of described I type sectional shelf-unit connect.
The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, two bare bracket junctions of described I type sectional shelf-unit are totally-enclosed.
The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, described support lateral surface adds non-slip hook.
The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, the one or both ends of described support are provided with retracting device, this retracting device is configured to: the support outside is annular fixed coil, the support inboard is a recovery coil, rounded or the font of recovery coil, single R ring of each skeleton of line process of fixed coil or two R ring enter and pass recovery coil in the support, when fixing 8 font recovery coil, only fix one of them ring, another ring is positioned at the support several points of fate down suitable for reading and is fixed in rack inner wall.
The invention has the beneficial effects as follows:
The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, not yielding after being compressed, be easier to take out, do not discharge the distortion and can separating or be used in combination of overlapping each other between the skeleton that support is adjacent according to the pathological changes situation because of pushing.

(5) specific embodiment
The non-lumen of vessels pipe holder of recyclable combination type of the present invention or monomer overlay film, described support is with the bending of medical high resiliency stainless steel silk Z type, crooked summit can be single R ring (Fig. 3) or two R ring (Fig. 4), rivet with similar stainless steel tube at two ends, form skeleton, two joints or more piece skeleton be connected to form the straight tube-like bare bracket (skeleton connect can the R ring intersect closely connect or adjacent two skeletons between slightly leave several millimeters distances, see Fig. 2), bare bracket is inside and outside all or part of coated with polyethylene, polyurethane or silicon rubber film.Such straight tube support can be used for trachea or bronchus (trachea or bronchial stent monomer are seen accompanying drawing 1) separately, combination is used for trachea and left and right sides bronchus (sectional shelf-unit is seen accompanying drawing 1).The I type sectional shelf-unit that can form a band angle when two identical or different supporting band angles of diameter connect; I type sectional shelf-unit and a straight tube support equipped form II type sectional shelf-unit (seeing accompanying drawing 1); II type sectional shelf-unit also can be made into the integral support of a bifurcated, i.e. III type integral support.III type integral support can be used for the interior support at trachea carina place.When I type sectional shelf-unit is used for a trachea and a laterobronchus, but two protrusion place perforates that support connects, for laterobronchus is ventilated; When being used to seal a laterobronchus pleural fistula, the support junction is totally-enclosed.Such support also can be used for esophagus (Fig. 1, Fig. 2), pylorus, 12 duodenum 12, rectum etc.Support can locally be removed the overlay film reserved passageway, for special requirement.The support lateral surface can add the non-slip hook 3 (Fig. 2) that prevents that support from sliding.The upper end of support or two ends are provided with retracting device (Fig. 5), retracting device is configured to: the support outside is annular fixed coil, the support inboard is a recovery coil, recovery coil can be rounded or 8 fonts (8 font recovery coil are mainly used in long-term placing rack, recovery when being covered might support suitable for reading) by esophageal tissue's hypertrophy, the line of fixed coil enters through the R ring of each skeleton and passes exhausting line in the support and enclose fixation, when fixing 8 font recovery coil, only fix one of them ring, another ring is positioned at the support several points of fate down suitable for reading and slightly is fixed in rack inner wall.Use the recover (Fig. 6) of configuration in human body, to take out or to adjust support.Because all there is exhausting line at the two ends of support,, utilize the exhausting line of the support other end still can take out support even support displacement back is rotated 180 ° at gastric.The sleeve pipe of the recover under the X line monitors is 9-10F, can be in the pipe in addition by the position of seal wire to guide recover to advance of 1 millimeter of a diameter, and the sleeve pipe of the recover under the gastroscope direct-view is 6-7F, sleeve pipe can be by the biopsy hole of gastroscope.
