It (is brought out from the big opening end of pre-tightening sleeve into osculum) when set, sheathed catheter realizes further compression to valve, then uses sheathed catheter
Valve pressure is held stowing dimensions by middle pressure grip, while valve being loaded into transportation system.It can be seen that the utility model knot
Structure is simple, low manufacture cost, easy to operate, is substantially shorter the valve loading time, so as to shorten the overall operation time.
The utility model is not only simple in structure, and cost of manufacture is lower, be can be used as disposable consumptive material and is provided, and operates
Simply the valve loading time is substantially shorter so as to shorten the overall operation time.
Embodiment described above is only that preferred embodiments of the present invention are described, not practical to this
Novel range is defined, and under the premise of not departing from the spirit of the design of the utility model, those of ordinary skill in the art are to this
The various changes and improvements that the technical solution of utility model is made should all fall into the protection that the utility model claims book determines
In range.
