Embodiment 1

[0032] like figure 1 as well as figure 2 As shown, it is a schematic diagram of the marking structure and an end projection view of the first embodiment of the present invention. The medical marking device 1 disclosed in the embodiment of the present invention includes a marking body 10 and a first anchoring structure 20 . The first anchoring structure 20 includes a fixing section 210 , a first extending section 220 and a first helical section 230 .

[0033] Here, the shape of the marking body 10 can be a hollow cylinder, but it is also conceivable that it can also be in other shapes, such as a sphere, an ellipsoid, a cuboid with relatively gentle edges and corners, etc. The reason why these shapes are selected is to avoid When it is implanted into the human body, too sharp edges and corners will bring discomfort to the human body and even stimulate the organs of the human body. That is to say, there are not too many restrictions on its specific shape. It should be pointed o...

Embodiment 2

[0042] like image 3 As shown, it is a schematic diagram of the marking structure of the second embodiment of the present invention. This embodiment is based on the first embodiment. Please refer to image 3 , the medical marking device 1 disclosed in the embodiment of the present invention also includes two end balls 30, and the two end balls 30 are respectively arranged on the terminal end 2302 of the first helical section 230 and the second end of the fixed section 210. end 2102 , and the diameter of the end sphere 30 is larger than the diameters of the fixing section 210 and the first helical section 230 . Furthermore, the end ball 30 disposed at the second end 2102 of the fixing section 210 clamps and fixes the first anchoring structure 20 in the marker body 10 .

[0043] Specifically, the two end spheres 30 are respectively arranged at the two ends of the first anchoring structure 20, and their diameters are larger than the diameter of the superelastic material of the f...

Embodiment 3

[0047] like Figure 4 As shown, it is a schematic diagram of the marking structure of the third embodiment of the present invention. This embodiment is based on the first embodiment. The medical marking device 1 disclosed in the embodiment of the present invention also includes a second anchoring structure 40. The second anchoring structure 40 includes a second extension section 410 and a second helical section 420 . The second extension section 410 is disposed on the second end 2102 of the fixing section 210 and extends in a direction relative to the first extension section 220; The first end 4101 of the second extension section 410, the terminal end 4202 of the second helical section 420 is located in the extension direction of the second extension section 410 and is separated from the first end 4101 of the second extension section 410 by a distance D2 ; Wherein, the helical direction of the second helical segment 420 is opposite to the helical direction of the first helica...

Abstract

The invention discloses a medical marking device for positioning. The medical marking device comprises a marking body and a first anchoring structure; the first anchoring structure comprises a fixed section, a first extension section and a first spiral section; the fixed section is nested into the marking body; the starting end of the first spiral section is arranged at the first end of the fixed section and extends in a direction far away from the fixed section; the first spiral section is arranged at the first end of the first extension section; the termination end of the first spiral section is located in the extension direction of the first extension section and separated from the first end of the first extension section by a distance. The medical marking device for positioning is used for solving the problem of lack of a medical device which can be positioned and identified easily and is not easy to move and capable of surrounding a focus in the prior art.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a medical marking device for positioning. Background technique [0002] At present, some operations that require the removal of certain organs of the human body are not difficult to find the lesion through existing medical methods, but doctors use minimally invasive or video-assisted thoracoscopic surgery (video-assisted thoracic surgery, VATS) to complete the surgical treatment At the same time, due to the limited field of view, it is very difficult to accurately identify and locate small lesions, which may cause deviation during surgical resection, and even cause surgical failure. In addition, in radiotherapy, for lesions that move with respiratory movement, it is difficult to accurately identify the location of lesions in real time. [0003] Therefore, there is an urgent need to invent a medical device that is easy to locate and identify and is not easy to move. When ...
