Abstract
The invention discloses a cardiac blood circulation auxiliary mechanism device, which comprises a cardiac apex sleevelet fixedly connected to a heart, and a blood pump body, wherein the cardiac apex sleevelet comprises a suture ring and a flexible skirt edge which is sleeved at the periphery of the suture ring; the blood pump body comprises an inlet pipe which is inserted into the heart; the inlet pipe is arranged on a rear cover of the blood pump body; the suture ring comprises a convex edge which is convexly arranged in the radial direction; a peripheral ring slot is formed between the convex edge and the flexible skirt edge; and a rotation sheet is arranged on the rear cover of the blood pump body and can be stretched into the peripheral ring slot, so that the cardiac apex sleevelet and the blood pump body are relatively axially fixed. In the invention, the rotation sheet is used for fixing the cardiac apex sleevelet and a blood pump, so that the cardiac apex sleevelet can be more conveniently and reliably connected with the blood pump; simultaneously, the axial dimension of the inlet pipe of the blood pump is reduced, so that the integral dimension of a left ventricle auxiliary blood pump is reduced, the implantation of the left ventricle auxiliary blood pump into a pleural cavity is facilitated, extrusion damages to the heart and a diaphragm are reduced at the same time, and the success rate of a surgery is greatly improved.
Description
Technical field
The present invention relates to the sanguimotor machinery of a kind of novel accessory heart, relate in particular to the syndeton of the sanguimotor machinery of a kind of accessory heart and heart, belong to technical field of medical instruments.
Background technology
Left ventricle assist blood pump, its arrival end is connected to heart apex of the heart position, and outlet is docked with on arteries.Heart and the arteries position of plugging into is all positioned at thoracic cavity.Between thoracic cavity and abdominal cavity, there is one deck diaphram.Diaphram is called again respiratory muscle, and diaphram declines, and thoracic cavity volume expands, air-breathing to help; When lax, diaphram rising sets back, and thoracic cavity volume reducing, to help expiration.Another effect of diaphram, is that thoracic cavity and abdominal cavity are separated, and diaphram self is fluid-tight.
Adopt the left ventricle assist blood pump of magnetic levitation technology, its destruction to blood is minimum, owing to not having in theory mechanical wear so good endurance.But magnetic suspension structure is complicated, cause pump housing size bigger than normal, therefore can only implant abdominal cavity.Existing product has the Levacor of WorldHeart company, and the DuraHeart of TERUMO company etc., are to be all implanted to abdominal cavity.
And when blood pump is implanted to abdominal cavity, operation will be opened thoracic cavity and abdominal cavity, will inevitably will bore a hole, and to guarantee that perforation place do not seep water on diaphram, significantly increase operating difficulty.Postoperative because diaphram is along with breathing up and down reciprocatingly, perforation place is easily gone wrong, and even tears diaphram.Greatly increased post-operative complication.To sum up, blood pump is implanted to abdominal cavity, doctor and postoperative care have been proposed to very high requirement, and be unfavorable for receptor's rehabilitation.
The overall dimensions of blood pump, except pump body dimension, size also includes an inlet and an outlet.The entrance of blood pump is between heart and the pump housing, and can its size is just directly connected to blood pump implanted thoracic cavity.
The implantation position of blood pump is below heart, and above diaphram, heart and diaphram are oppressed in oversize meeting simultaneously, not only affect cardiac rehabilitation, can have influence on normal respiratory function simultaneously, even cause the appearance of other complication.
