The marker of interior small space occupying lesion, and the positioning system comprising marker to be accurately sent into intrapulmonary designated position.
Background technique
For the early stage of lung cancer, pernicious small pulmonary artery is suspected, surgical operation is the best approach of radical cure.However only rely on CT
Fault image is difficult the accurate judgement lesion position in actual operation, to precisely cut off lesion region.Even if by large stretch of
Lung tissue's excision, it is also difficult to pathological tissues are quickly found out and taken out from vitro tissue, to obtain pathological replacement in art, guidance
Further modus operandi.
Application No. is 201610167531.9 Chinese invention patent applications to disclose a kind of structure of intrapulmonary marker, this
After kind structure implantation intrapulmonary, doctor can not intuitively have found marker position, perceptible markings object need to be removed by hand, to accurate
It was found that marker still has very big difficulty.
Application No. is 201410113859 Chinese invention patent applications to disclose a kind of mark that can be found from lungs surface
Remember object, but its structure is not suitable for the lesion of any depth not only, and it is also not suitable for by burr in the fixed mode of intrapulmonary
In this hollow organ of lung.
Therefore, it is necessary to providing one kind is securable to intrapulmonary, and can from lung surface directly from and support to lung tissue into
The device of row lifting facilitates the development of pulmonary surgical procedures at least partly to solve the above problems.
Summary of the invention
In order at least be partially solved the above problem, the present invention provides a kind of label for positioning the small space occupying lesion of intrapulmonary
Object, including tag body, the tag body include head and from the self-expanding that radially self expands after compression set release
Structure, the self-expanding structure are connected with the head, and the self-expanding structure is formed after compression set release has head

Specific embodiment
In the following description, a large amount of details is provided so as to thoroughly understand the present invention.However, this field skill
Art personnel will be seen that, exemplarily only show the preferred embodiment of the present invention described below, and the present invention may not need one
Or multiple such details and be carried out.In addition, in order to avoid confusion with the present invention, for more well known in the art
Technical characteristic is not described in detail.
According to an aspect of the present invention, a kind of telltale mark system positioning the small space occupying lesion of intrapulmonary is provided.Fig. 1 goes out
The all parts or part that the entirety and telltale mark system of telltale mark system are included, such as marker and push
Device.In order to understand the position and role of these components or part in telltale mark system, first to telltale mark
System carries out globality description, thoroughly to understand the present invention.
As shown in Figure 1, telltale mark system 100 includes marker 10, and marker 10 is sent into intrapulmonary designated position
Conveying device 20, conveying device 20 include aciculiform puncture sheath 21 and pusher 22, before inflation be in strip marker 10
It is compressed in aciculiform puncture sheath 21, aciculiform puncture sheath 21 has push mouth 211 and liberation port 212, and pusher 22 is located at push mouth
211, when pulmonary surgical procedures, marker 10 is released by the liberation port 212 of aciculiform puncture sheath 21 using pusher 22, makes marker
10 are anchored in the neighbouring lung tissue of the small space occupying lesion of intrapulmonary.
Aciculiform puncture sheath 21 and pusher 22 belong to the prior art, and marker 10, mark is described in detail below in conjunction with attached drawing
Note object 10 is for marking the positions such as the lesion locations, such as tumour, tubercle of lung.
Refering to attached drawing 2a to Fig. 2 d, the marker 10 of the small space occupying lesion of positioning intrapulmonary of one embodiment of the invention includes
Tag body 11 and flexible lifting line 12.Tag body 11 includes head and discharges from compression set (i.e. aciculiform puncture sheath 21)
