Heart valve transporter
Technical Field
The invention relates to the technical field of medical equipment, in particular to a heart valve conveyor.
Background
The treatment mode of heart valve diseases is mainly to adopt the transvascular technology of soft catheter delivery and implantation artificial heart valve, at present artificial valve adopts the balloon-expanded valve, press-fit on the middle tube of the conveyer before balloon-expanded valve delivery, before entering the blood vessel, move artificial valve to the saccule position again, under CT development, artificial valve itself is pressed on the middle tube, if pressing too tightly and installing at the end of soft catheter in the state of crimping, the soft catheter advances to the implantation position through the blood vessel of patient, the artificial valve that is located at the catheter top is supported and opened through the saccule inflation, can effectively improve the treatment efficiency by adopting this treatment mode, alleviate patient's misery, at present, the heart valve conveyer of present, in order to prevent artificial valve from coming off from the saccule, the means that adopts is symmetrical to set up two jack catches on the stay tube, two jack catches are all located the saccule inside, artificial valve cover is established on the saccule with the state of crimping, because the saccule surface is comparatively smooth, when the heart valve conveyer will cover artificial valve when the saccule is carried inwards to the human body, artificial valve can follow the saccule, this drops, this leads to low efficiency and makes the patient's suffering from the operation success rate, and has born the secondary misery.
