Abstract

The invention discloses a delivery device and system for interventional devices. The device comprises a delivery rod, one end of the delivery rod is sleeved with a near-end sleeve, and the other end of the delivery rod is sleeved with a far-end sleeve; a connecting piece is arranged at one end of the near-end sleeve and comprises an extending part hinged to the near-end sleeve and a clamping partcapable of being clamped with a limiting hole; in an initial state, the delivery rod and the connecting piece extend into the far-end sleeve, the extending part is located between the outer surface ofthe delivery rod and the inner surface of the far-end sleeve, and the clamping part and the limiting hole are clamped and fixed; and in a using state, the delivery rod is separated from the far-end sleeve, and the connecting piece can rotate towards the interior of the far-end sleeve to enable the clamping part to be separated from the limiting hole. In the patent, the near-end sleeve is fixed onthe far-end sleeve through the connecting piece, the delivery rod matched with the device is arranged, and the near-end sleeve and the far-end sleeve can be separated by pulling out the delivery rodand the near-end sleeve from the near end in sequence, and the device is simple in structure, convenient to operate and high in reliability.

Description

technical field [0001] The invention relates to the field of interventional medical equipment and push components, in particular to an interventional device delivery device and system. Background technique [0002] With the in-depth research of minimally invasive technology, interventional medical equipment continues to develop. The release of interventional medical equipment often adopts a delivery device. The interventional medical device enters the target position in the human body through a minimally invasive opening. The delivery device is removed to complete the release of the interventional medical device. However, in the prior art, the delivery device is often complex in structure, difficult to operate, and easily affects the shape of the interventional medical device during the detachment process. Therefore, whether there is a delivery device that is simple in structure, easy to operate and reliable is a technical problem that those skilled in the art expect to so...
