Interventional medical instrument connecting device and using method thereof

Abstract

The invention provides an interventional medical instrument connecting device and a using method thereof. The interventional medical instrument connecting device comprises an implant, a storage cabinand a propeller, wherein the implant and the storage cabin are both woven and shaped by nickel-titanium alloy wires, the storage cabin is fixedly connected to the axis of the implant through a connecting body, the propeller is movably arranged in a connecting channel, a pair of telescopic grooves which are through inside and outside is formed in the side edge of the propeller, clamping blocks aremovably arranged in the telescopic grooves respectively, extrusion springs are fixedly installed between extrusion plates and the inner wall of an extrusion cabin, and an air bag communicates with anexternal inflation and deflation device through a guide wire guide pipe. Compared with a traditional threaded connection mode, the interventional medical instrument connecting device has the advantages that the length of the connecting body is shortened, the propeller does not need to be repeatedly rotated, meanwhile, implantation of the implant can be conducted, the implanted implant can be rapidly taken out, the implantation and taking-out time is shortened, the pain of a patient is relieved, and meanwhile the safety of an operation is improved.

Description

technical field [0001] The invention relates to the technical field of interventional medical equipment, in particular to an interventional medical equipment connection device and a method for using the same. Background technique [0002] Catheter interventional therapy is a treatment method with more and more widely applicable fields. It can place various materials, devices and drugs to the human heart, arteriovenous blood vessels, such as atrial septal defect (ASD) occluder, Ventricular septal defect (VSD) occluder, patent ductus arteriosus (PDA) occluder and patent foramen ovale (PFO) occluder, etc., can all be placed in the defect site of the heart through a catheter to seal the defect, thereby Treat congenital heart disease. [0003] An interventional medical device connection device and its use method in the prior art with the application number "CN201010265431.2", the interventional medical device connection device includes an implant and a pusher, one end of the imp...

AI Technical Summary

Problems solved by technology

[0004] However, the above-mentioned interventional medical device connection device and its use method still have obvious defects in the process of use: although the above-mentioned device overcomes the disadvantages of the traditional screw connection method, it also produces new disadvantages in use, that is, the traditional Although the threaded connection method may hinder the radial freedom of the instrument and increase the risk of surgery, the threaded connection method can be threaded again after the implant is released, thereby creating conditions for the recovery of the implant. After the release of the implant, due to its soft and uncertain shape, the control wire cannot be guaranteed to enter the keyhole again after release, which makes it difficult for the implant to be recovered again. This release method is not conducive to remedial adjustment in the later stage , which greatly increases the difficulty of taking out the implant, which in turn greatly increases the risk of postoperative use
