Post-release device for medical instrument implant

Abstract

The invention provides a medical instrument implant post-release device, and relates to the field of medical instruments, a first center hole is formed in a first locking part, a first cutting groove is formed in the peripheral surface of the rear end of the first locking part, and a first curved surface is formed on the top surface of a groove body of the first cutting groove; a second center hole is formed in a second locking part and communicates with a pipe cavity of the slender pipe, a second cutting groove is formed in the circumferential surface of the front end of the second locking part, a second curved surface is formed on the top surface of a groove body of the second cutting groove, and an anti-falling limiting part is connected to the front end of the second locking part; in the locking state, the first curved surface and the second curved surface are buckled with each other, the front end of a control cable penetrates through the first center hole and the second center hole, and the anti-falling limiting part is matched with the control cable to limit the front end of the second locking part in the first cutting groove. The post-release device at least relieves the problem that in an existing post-release device capable of mechanically releasing a medical instrument implant, once the medical instrument implant is separated from a conveying pipe, the medical instrument implant cannot be withdrawn back to the conveying pipe, and consequently mistaken thrombus can be possibly caused.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a release device for implanted medical devices. Background technique [0002] Percutaneous transcatheter embolization is defined as the intravascular deposition of a device or agent (solid or liquid) that produces intentional vascular occlusion. The occlusion of an embolized vessel can be performed at any level, from the aorta or vein to the capillary bed, and the embolization can be temporary or permanent in nature. During surgery, the embolic substance is injected or delivered into the target vessel through the catheter, so that Vascular occlusion so as to achieve the intended therapeutic purpose. [0003] Through embolization, congenital or acquired abnormal vasculature can be eliminated, thereby improving the clinical situation. This method has also been used for occlusion of normal vasculature to relieve tumors and tissue ablation of these normal or abnormal vessels...
