Embodiment Construction
[0021] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0022] The invention provides a marker in the lung, which is used for marking the lesion position of the lung, and can facilitate doctors to quickly find the lesion position during surgery. The intrapulmonary marker of the present invention is an elastic self-expandable structure made of a memory alloy. By utilizing the elasticity of the self-expandable structure, when the marker is delivered by a compression device (such as a general-purpose catheter or a special delivery instrument), the marker It is in the shape of a strip and is pushed out of the catheter after being sent to the lungs. Because the memory alloy has the ability to restore the original shape, and the density of the lung tissue is extremely small, the self-expanding structure expands to the original shape by itself, thus being clamped at the lesion , and then play the role of i...
