A ventricular connection component

Abstract

The invention provides a heart ventricle connection assembly which comprises a suture ring assembly and a blood pump connection assembly. The suture ring assembly not only comprises a suture ring and a suture ring seat, but also comprises a connection hinge pin; the connection hinge pin passes through a through hole formed in the suture ring seat and is locked with a screw thread head at one end of the connection hinge pin by a nut to be arranged on the suture ring seat, so that the connection hinge pin freely rotates in the through hole; the blood pump connection assembly comprises an inlet sintering pipe sleeved on an inner pipe of an inlet of a blood pump; the periphery of the inlet sintering pipe is provided with a connecting groove; and by rotating the connection hinge pin, a cylindrical surface on a circular arc tangent plane, which is arranged on the connection hinge pin, falls into the connecting groove and the suture ring seat is clamped and fixed on the inlet sintering pipe. The heart ventricle connection assembly has a simple structure, has a small axial size after connection and is beneficial for being implanted into a human body to stably play functions; and by the device designed by the invention, rapid connection of a heart ventricle auxiliary device and the heart can be implemented and not only is time of the whole operation process shortened, but also operation risk is reduced.

Description

technical field [0001] The invention relates to the technical field of ventricular assist circulation, and more specifically, relates to a ventricular connection assembly. Background technique [0002] A blood pump or a ventricular assist device is a small pump with variable speed and variable capacity that is used to completely replace the work of the heart. The ventricular assist device contains an inlet and an outlet. When implanted in the heart, the outlet is connected to the aorta through the artificial blood vessel, and the inlet is connected to the ventricle through the apex opening. The ventricular assist device is connected to the heart through the ventricular connection structure between the inlet and the outlet connected. Since the ventricular assist device is used for implanting in the thoracic cavity and surrounding the heart with complex distribution of organs, the size is an important indicator to realize its function during use. Therefore, it is required tha...

Problems solved by technology

[0003] However, the structure of the existing ventricular connection device used to connect the ventricular assist device is still relatively complicated, and the axial size is relatively large, which has a certain impact on its operation after implantation in the body

In addition, some ventricular connection devices need to use other auxiliary tools or add redundant actions during the connection process, which virtually prolongs the operation time and reduces the connection efficiency when it is implanted in the heart.
