Problems solved by technology

Due to its poor controllability, hydrolytic release coils are rarely used clinically; most of the electrolytic release coils used in clinical practice have the problem that the release time is too long or the release time is unstable, which affects the operation time; the mechanical release coils Simple snap-on design, although the spring coil can be released instantly, it reduces the controllability of the spring coil during the filling process, especially when the spring coil is pushed out of the channel, it is difficult to pull back or push

Abstract

The invention provides a machine detachment device and a machine detachment system, and relates to the field of medical instruments. The machine detachment device comprises a spring ring, a detachmentconnecting piece, a pushing rod and a core wire; the spring ring is fixed to one end of the detachment connecting piece, one end of the pushing rod is a break-off end which can be broken off, the other end of the pushing rod is matched with the end, away from the spring ring, of the detachment connecting piece, the core wire is inserted into the pushing rod coaxially, one end of the core wire isfixedly connected with the break-off end, the other end of the core thread penetrates the end portion, matched with the pushing rod, of the detachment connecting piece and is connected with the end portion, matched with the pushing rod, of the detachment connecting piece, and the break-off end after being broken off can drive the core thread to be drawn out. By means of the machine detachment device, instant detachment of the spring ring can be achieved, and the controllability of the spring ring before detachment can be guaranteed; according to the formed machine detachment system, before detachment, the controllability of the embolism spring ring is high, and instant detachment can be achieved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a mechanical release device and a mechanical release system. Background technique [0002] Since the 1980s, clinical interventional techniques have been used to embolize aneurysms. In the early days, detachable balloons were used as embolization embolisms. The aneurysm cannot be fully embolized. The coil can fully fill and adapt to the shape of the aneurysm lumen, so the embolization of aneurysms with coils has become the main treatment for aneurysms. [0003] In the interventional operation of coil embolization of aneurysms, it is necessary to deliver coils of different sizes and different three-dimensional or two-dimensional shapes into the aneurysm from large to small until the springs in the aneurysm can densely pack the entire aneurysm. Clinically, interventional surgery for each aneurysm usually requires several to a dozen coils to complete the dense packing of the aneurysm...
