Description
Technical field
This utility model relates to field of medical article technology, particularly relates to a kind of covered stnet of ease of assembly.
Background technology
Coronary arterial perforation is one of complication serious in PCI art, and incidence rate is 0.50% ~ 0.93%.First use sacculus low-pressure to expand site of perforation after there is coronary arterial perforation, consider surgical intervention if site of perforation still can not be closed or implant PTFE covered stnet.Current domestic each large cardiac intervention center and training base routine have PTFE covered stnet JOSTENT, due to expensive, and general non-intervention centre pipe room is not conventional for leaving with goods, therefore when without covered stnet, there is arteria coronaria perforation, Acute cardiac tamponade, sacculus low pressure can only be taked to expand and prepare Cardiac Surgery Coronary Artery Bypass simultaneously or turn higher level's hospitalize, patient in the process mortality rate increases.
Utility model content
Technical problem to be solved in the utility model is, for the above-mentioned deficiency of prior art, proposes a kind of convenient making, the simple covered stnet of structure.
The technical scheme that this utility model solves the employing of its technical problem is: a kind of covered stnet of ease of assembly, comprise and scribble by appearance the sacculus 100 that polytetrafluoroethylene PTFE material makes, described sacculus 100 is cylindrical, and sacculus two ends are cut is formed with parallel cuts 110; Also comprise the network 200 with diamond-mesh; Described network 200 is attached at sacculus 100 inner surface, and end, network 200 two ends is concordant with the parallel cuts 110 at sacculus 100 two ends; Described parallel cuts 110 can, by heat seal, make network 200 be sealed in sacculus 100.
The covered stnet of described ease of assembly, described sacculus 100 thickness is 75-80 μm.
The covered stnet of described ease of assembly, diamond-mesh 210 area of described network 200 is increased to middle part gradually by two ends.
The covered stnet of described ease of assembly, described network diamond-mesh 210 area is at 2-12mm
2between, minimum area is 2-3mm
2, maximum area is 10-12mm
2.
Described sacculus is made up of polyamide material.
This utility model adopts sacculus common in existing intervene operation room as the film of support, adopts heat seal process to be sealed at sacculus two ends, makes covered stnet structure of the present utility model simple, with low cost.Doctor, when not obtaining the covered stnet prepared, also can draw materials whenever and wherever possible, and ease of assembly, prepares covered stnet voluntarily, races against time for treating patient in time.
Accompanying drawing explanation
Fig. 1 is the schematic cross-section of this utility model sacculus;
Fig. 2 is the expansion schematic diagram of this utility model network.
In figure: 100. sacculus, 110. parallel cuts, 200. networks, 210. diamond-mesh.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but this utility model be not limited to these embodiments.
Embodiment 1: please refer to Fig. 1, Fig. 2, this utility model covered stnet, it comprises and scribbles by appearance the sacculus 100 that polytetrafluoroethylene PTFE material makes, and described in described sacculus, sacculus 100 is cylindrical, and sacculus two ends are cut is formed with parallel cuts 110; Also comprise the network 200 with diamond-mesh; Described network 200 is attached at sacculus 100 inner surface, and end, network 200 two ends is concordant with the parallel cuts 110 at sacculus 100 two ends; Described parallel cuts 110 can, by heat seal, make network 200 be sealed in sacculus 100.
The covered stnet of described ease of assembly, described sacculus 100 thickness is 75 μm.
The covered stnet of described ease of assembly, diamond-mesh 210 area of described network 200 is increased to middle part gradually by two ends.
The covered stnet of described ease of assembly, described network diamond-mesh 210 area minimum area is 2mm
2, maximum area is 10mm
2.
Described sacculus is made up of polyamide material.
Embodiment 2: please refer to Fig. 1, Fig. 2, this utility model covered stnet, it comprises and scribbles by appearance the sacculus 100 that polytetrafluoroethylene PTFE material makes, and described in described sacculus, sacculus 100 is cylindrical, and sacculus two ends are cut is formed with parallel cuts 110; Also comprise the network 200 with diamond-mesh; Described network 200 is attached at sacculus 100 inner surface, and end, network 200 two ends is concordant with the parallel cuts 110 at sacculus 100 two ends; Described parallel cuts 110 can, by heat seal, make network 200 be sealed in sacculus 100.
The covered stnet of described ease of assembly, described sacculus 100 thickness is 80 μm.
The covered stnet of described ease of assembly, diamond-mesh 210 area of described network 200 is increased to middle part gradually by two ends.
The covered stnet of described ease of assembly, described network diamond-mesh 210 area minimum area is 3mm
2, maximum area is 12mm
2.
Described sacculus is made up of polyamide material.This kind of support is adopted to be suitable for very much the sacculus with parallel cuts of the present utility model.Support two ends are large compared with its lifting surface area of little diamond-mesh, and when parallel cuts is by heat seal, this diamond-mesh can discharge enough tensile forces and make support firmly be fixed on sacculus inner surface.
The larger diamond-mesh 210 in middle part is convenient to expansion to block coronary arterial perforation, reaches the object of quick-acting haemostatic powder.Choosing according to actual sacculus thickness of diamond-mesh 210 area is different and different from length.
Each diamond-mesh 210 of network 200 is enclosed space.
Adopt covered stnet prepared by this utility model, raw material easily obtains, prepare simply, ease of assembly.Even if doctor can not find the covered stnet of finished product for the moment in operation process, it also obtains covered stnet of the present utility model by following steps:
First: used support sacculus cutting is formed parallel cuts 110;
Second: network 200 is filled in the support sacculus 100 after cutting;
3rd: utilize alcohol burner or lighter etc. to heat tweezers, use tweezers as parallel cuts 110 heat seal of heat seal instrument by support sacculus 100.
The covered stnet that doctor adopts said method obtained can shutoff arteria coronaria site of perforation rapidly, prevents cardiovascular from surprisingly occurring.
Specific embodiment described herein is only to the explanation for example of this utility model spirit.This utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
