Problems solved by technology

However, even minimally invasive small incision hybrid surgery still has the possibility of occluder falling off, leading to major complications such as patient death or embolism
However, the delivery system of the existing interventional technology is mainly used for complete interventional therapy, which cannot well meet the needs of minimally invasive small incision hybrid surgery.

Embodiment Construction

[0032] figure 1 , figure 2 , image 3 , Figure 4 The shown flexible release delivery system of Embodiment 1 of the present invention includes a delivery sheath 10, a delivery member including a steel cable 31 and a flexible connector, the flexible connector is a fuse 32 with sufficient toughness, and the end of the fuse 32 is connected to a handle 321 connection. Take the placement of the occluder interventional instrument as an example. When in use, first pass one end of the fuse 32 through the plug head side of the occluder to be flexibly connected with the occluder, and then pass the two ends of the fuse through the guide sheath 40 (the occluder will be blocked) The device is sent into the auxiliary part of the delivery sheath), the proximal end of the fuse 32 is connected to a handle 321, the steel cable 31 is also threaded through the guide sheath 40 and connected to the occluder 60, and the occluder is received in the guide sheath; subsequently, Such as image 3 A...

Abstract

The invention relates to a transportation device for inputting an intervention apparatus into a selected area of a human body. A soft disengagement transportation system comprises a transportation pin, and a transportation component for pushing the intervention apparatus to an affected part, wherein the transportation component in the transportation pin comprises a soft connecting component which is movably connected with the intervention apparatus. The transportation device is provided with the soft connecting component which is still connected with the intervention apparatus and maintains soft connection with the intervention apparatus after a rigidity connecting component disengages, the effect of tractive force on the real state of the intervention apparatus is greatly reduced; at the same time, if an intervention product falls off or the state of the product is not ideal, the device can withdraw the intervention apparatus through the soft connecting component and avoid the occurrence of death or embolism and other serious complication of a patient caused by the shedding of a blocked device.

Description

technical field [0001] The invention relates to a device for delivering a medium into or onto a human body, especially a delivery device for delivering an interventional device into a selected area in a human body. Background technique [0002] Interventional technology was developed in the late 1970s. Under the guidance of imaging medicine (X-ray, ultrasound, CT, MRI), it uses percutaneous puncture or passes through the original channel of the human body to deliver interventional devices through a special sheath. To the lesion site for diagnostic imaging and treatment. [0003] Nowadays, when cardiovascular diseases such as ventricular septal defect (VSD), atrial septal defect (ASD) and patent ductus arteriosus (PDA) are treated by interventional technology, the occluder is implanted into the affected part of the human body through interventional methods to achieve treatment. Purpose. In this method, a delivery track is first established through the delivery sheath to rea...
