Problems solved by technology

The interface used in the prior art has a complex structure, large size, and thick tube wall, resulting in insufficient design space for other components. The interface of the above structure is still difficult to separate, or the external force of separation is too large, destroying the interface structure or causing interface wear and many other problems.

Abstract

The invention discloses a human heart implantation device delivery interface and a method for using the same. Matching; a second connecting piece, the end of which is provided with a buckle matched with the buckle groove of the first connecting piece; a lining core, which is installed on the inner peripheral side of the first connecting piece and the second connecting piece ; The said buckle groove and the buckled surface of the buckle are inclined surfaces. When the lining core is arranged in the buckled area, the first connecting piece and the second connecting piece are in a connected state; when the lining core is pulled out of the buckled area, The second connecting piece is pulled to generate a radial component force on the buckling surface, so that the buckle moves in the axial direction of the interface and leaves the buckle groove, so as to separate the first connecting piece and the second connecting piece. Both the two connecting pieces are set as thin-walled elements, which reduces the volume of the interface and facilitates the connection and separation of the interface, and further utilizes the inclined buckle surface and the lining core to control the connection state.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a delivery interface for a human heart implant device and a method for using it. Background technique [0002] Human heart implantable devices are small in size and need to be manipulated at the handle end, thus requiring a functional and reliable delivery system and a detachable structural interface (or joint) of the device. The interface used in the prior art has a complex structure, large size, and thick tube wall, resulting in insufficient design space for other components. The interface of the above structure is still difficult to separate, or the external force of separation is too large, destroying the interface structure or causing interface wear and many other problems. Therefore, there is an urgent need to provide a new human cardiac implant delivery interface and use method to solve at least one of the above-mentioned problems in the prior art. Contents of th...
