The invention discloses a detachable implantation device and its operating method, comprising: a first connecting element with an anchoring portion at one end and at least one first connecting portion extending axially at the other end; a second connecting element , the side wall near the end of the first connecting element is provided with at least one second connecting portion extending in the radial direction; after the anchoring portion anchors the human tissue, it pulls the first connecting element toward the second connecting element, Then rotate the first connecting element along the axis of the first connecting element, so that the first connecting part and the second connecting part are clamped. The present invention can achieve the effect of locking the two connecting parts at any angle; and after the clamping, the clamping angle of the clamping part of the implant instrument can be adjusted, which improves the safety of the operation and the convenience of operation; the two connecting elements After locking, it can be unlocked at any time, allowing the operator to reposition the target point; the double connection method is adopted to improve the stability of locking; the invention has simple structure and low production cost.
Description
technical field [0001] The invention relates to the technical field of medical devices, in particular to a detachable implant device and an operating method thereof. Background technique [0002] Human implanted devices are small in size and high in precision. Especially for the anchoring and clamping devices used to treat heart valve diseases, the requirements for structural design and connection reliability are particularly stringent. The current clamping instrument is provided with a clamping arm and a rotating arm, which are responsible for clamping tissues so as to achieve the purpose of reducing the valve annulus. The anchoring component and the holding device need to be locked together to prevent the device from detaching from the tissue. Due to the limited length of the locking mechanism of the clamping instrument, the anchoring part and the clamping instrument can be locked only when the clamping arm is clamped to a small angle. But when there are many tissues to...
