Abstract

The utility model relates to an integral butterfly-shaped close device which is used for curing the congenital heart diseases, such as the patent ductus arteriosus, the atrial septal defect and the septal defect. The utility model is mainly composed of an elastic integral butterfly-shaped close device body 5, a conjoined body 4, a carrier pipe 1, a propulsion pipe 2, a dragline 3, etc. The utility model can repair the defect position of the heart and close the heart completely by cutting a cut of 0.5 cm after processing local anesthesia at the femoral vein of a patient under the state that the consciousness of the patient is wide awake, without full anesthesia and without operation of opening chest; the patient can move free after 2 hours of the operation, with no side effects of heart blemish and inorganic body damage.

Description

Disjunctor dish closer

This utility model belongs to a kind of medical apparatus and instruments.

Patent ductus arteriosus, atrial septal defect, ventricular septal defect are human modal congenital heart disease, the treatment of congenital heart disease always is that the Cardiac surgeon anaesthetizes sb. generally to patient, carry out opening breast after the extracorporeal circulation, cut heart and under direct-view, repair damaged operation, in mending course, sew up defect owing to cut heart, so except that infringement, usually undermine heart significant points---conducting system of heart, cause more severe impairment to the cardiac muscle of heart.All operating difficulty is big, equipment requirements is smart, expense is high, and bigger to patient's infringement.

The purpose of this utility model provide a kind of patient do not need to apply general anaesthetic liquor-saturated, do not need out breast, realize the osculum that following of wide-awake state cuts a 0.5cm at femoral vein patient and can repair the damaged disjunctor dish closer of congenital heart disease.

Major technique content of the present utility model is to be made up of carrier pipe, propulsion tube, stay cord, disjunctor, elasticity disjunctor dish closer body etc., wherein, disjunctor is fixedly mounted on the center of elasticity disjunctor dish closer body vertically, the two ends that the stay cord string is crossed the ring of disjunctor and stay cord seal in from the rear end of propulsion tube from the front end of propulsion tube and draw, the propulsion tube string is in the inside of carrier pipe, and the length of propulsion tube is than carrying pipe range.

That advantage of the present utility model is not need to apply general anaesthetic is liquor-saturated, do not need open chest surgery, realize under the wide-awake state patient, only after the quiet place of thigh local anaesthesia, cut the otch of an about 0.5cm, this utility model can be delivered to the heart atrial septal defect place repairs defect fully, 2 hours patients of postoperative just can be free movable, there is no heart and injury, the side effect of inorganic body damage; This utility model is reasonable in design, science is strong, reliable in function, operation technique are simple.

Fig. 1 is in the state diagram that correct heart atrial septal defect is repaired the position for elasticity disjunctor dish closer body of the present utility model;

Fig. 2 is not subjected to the shape figure under the situation of external force for elasticity disjunctor dish closer body;

Fig. 3 is that elasticity disjunctor dish closer body is pushed the shape figure in the inlet pipe progradation in carrier pipe.

Provide embodiment of the present utility model as follows in conjunction with the accompanying drawings:

This utility model such as Fig. 1, Fig. 2, shown in Figure 3, mainly form by carrier pipe 1, propulsion tube 2, stay cord 3, disjunctor 4, elasticity disjunctor dish closer body 5 etc., wherein, disjunctor 4 is fixedly mounted on the center of elasticity disjunctor dish closer body 5 vertically, stay cord 3 was gone here and there the two ends of the ring of disjunctor 4 and stay cord 3 and is sealed in from the rear end of propulsion tube 2 from the front end of propulsion tube 2 and draw, propulsion tube 2 strings are in the inside of carrier pipe 1, and the length of propulsion tube 2 is longer than carrier pipe 1.

Operation principle of the present utility model is as follows:

1., carrier pipe 1 is delivered to heart arteries and veins atrial septal defect along vein blood vessel, the rear end is exposed at outside the human body from femoral venous incision;

2., an end of stay cord 3 was gone here and there from the ring of the disjunctor 4 of elasticity disjunctor dish closer body 5, and the two ends of stay cord 3 are together pulled out from the rear end from the front end introducing of propulsion tube 2, elasticity disjunctor dish closer body 5 is withstood on the front end of propulsion tube 2 under the pulling of stay cord 3;

3., elasticity disjunctor dish closer 5 is pinched into an axial column, fill in the carrier pipe 1, and deliver to the heart atrial septal defect place at the thrust lower edge of propulsion tube 2 carrier pipe, when the first half of the elasticity disjunctor dish closer body 5 of pinching into axial column is released by the heart atrial septal defect place and from carrier pipe 1 when removing the constraint of carrier pipe 1, the first half of elasticity disjunctor dish closer body 5 is by self its intrinsic shape of elastic return, be attached to a side at heart atrial septal defect position, optimum position with stay cord 3 and propulsion tube inching elasticity disjunctor dish closer body 5, withstand elasticity disjunctor dish closer body 5 and outwards twitch carrier pipe 1 with propulsion tube 2 then, the latter half that makes elasticity disjunctor dish closer body 5 is also by himself elastic return intrinsic shape, and reuse stay cord 3 and propulsion tube 2 are adjusted the elasticity disjunctor dish closer body 5 best relative positions with heart atrial septal defect position;

4., an end of stay cord 3 is pulled outwardly, to stay cord 3 is all extracted out in body, propulsion tube 2 is extracted out in body again, carrier pipe 1 is extracted out in body again, the repairing of finishing heart atrial septal defect is promptly closed.

Wherein, elasticity disjunctor dish closer body 5 adopts materials such as politef, silicon rubber foam, polyethylene from high pressure process to make, and also can add within it increases elastic muscle; Carrier pipe 1 adopts plastics or silicon plastic tube etc. to make; Disjunctor 4 usefulness hard materials such as rustless steel or Nitinol etc. are made.

Claims

1, a kind of disjunctor dish closer, it is characterized in that forming by carrier pipe, propulsion tube, stay cord, disjunctor, elasticity disjunctor dish closer body, wherein, disjunctor is fixedly mounted on the center of elasticity disjunctor dish closer body vertically, the two ends that the stay cord string is crossed the ring of disjunctor and stay cord seal in from the rear end of propulsion tube from the front end of propulsion tube and draw, the propulsion tube string is in the inside of carrier pipe, and the length of propulsion tube is than carrying pipe range.
