Abstract

The invention discloses a detachable implantation instrument and an operation method thereof. The detachable implantation instrument comprises a first connecting element and a second connecting element, wherein one end of the first connecting element is provided with an anchoring portion, and the other end of the first connecting element is provided with at least one first connecting portion extending in the axial direction; the side wall, close to an end of the first connecting element, of the second connecting element is provided with at least one second connecting portion extending in the radial direction; after the anchoring portion anchors human tissue, the first connecting element is pulled to the second connecting element, and then the first connecting element is rotated along the axis of the first connecting element so that the first connecting portion and the second connecting portion can be in clamped connection. The effect of locking two connecting pieces at any angle can be achieved; after clamped connection, the clamping angle of a clamping component of the implantation instrument can be adjusted, and the safety and operation convenience of an operation are improved; after the two connecting elements are locked, unlocking can be conducted at any time, and an operator can position a target point again; the locking stability is improved by adopting a double-connection mode; and the detachable implantation instrument is simple in structure and low in 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...
