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...

Abstract

The invention relates to a pulmonary marker, used for marking the lesion position of the lung. The pulmonary marker comprises a self-expanding structure which can radially expand automatically after being released from a compression device so as to realize marking. According to the pulmonary marker, due to the adoption of the self-expanding structure, when the lesion position is found during the lung examination, the pulmonary marker can be conveyed to the lesion position through a catheter or a conveyor, then the self-expanding structure is extruded and fixed by the pulmonary parenchyma after expanding at the lesion position, therefore, during the surgical operation, a doctor can rapidly locate the lesion position, thus the surgical time is shortened, the excision extension is reduced, and the postoperative quality of life of a patient is improved.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a marker in the lung. Background technique [0002] With the process of industrialization in China, environmental pollution, living stress, smoking and other bad living habits will significantly increase the incidence of lung diseases, especially lung cancer. With the advancement of imaging equipment, such as the promotion and use of low-dose spiral CT scanning, more and more asymptomatic people will be detected with early lung cancer or nodules of unknown nature. For these early lesions, radical surgery is the best treatment. However, early lesions are not only small in size, but sometimes their density is very close to that of normal lung tissue, and most of them cannot be accurately located during surgery. Surgical operations can only rely on extended excision to ensure the radical cure of the lesion. This surgical method will seriously reduce the postoperative quality of lif...
