Detailed Description
The following examples are intended to illustrate the invention, but are not intended to limit the scope of the invention. Unless otherwise specified, the technical means used in the examples are conventional means well known to those skilled in the art.
Based on the above purpose, the embodiment of the utility model provides an embodiment of axillary sentinel lymph node location and degree of depth measuring device before breast cancer art. Fig. 1 is a schematic view of the axillary sentinel lymph node location and depth measurement device before breast cancer operation according to the embodiment. As shown in fig. 1, the pre-operative axillary sentinel lymph node localization and depth measurement apparatus for breast cancer comprises a bowl-shaped body 1, the bowl-shaped body 1 having a bowl bottom end 101, a bowl opening end 102, and a bowl wall 103 connecting the bowl bottom end 101 and the bowl opening end 102, the bowl wall 103 extending from the bowl bottom end 101 to the bowl opening end 102. The bowl-shaped body 1 tapers from the bowl opening end 102 to the bowl bottom end 101. In summary, the bowl-shaped body 1 has most of the common features of a common bowl. Preferably, however, the bowl-shaped body 1 does not have a convex base, the bottom of which is an arc-shaped transition. The bowl-shaped body 1 is made of transparent materials, so that a doctor can observe readings through the bowl-shaped body 1. The center of the bowl bottom end 101 has a through hole. After the physician determines the location of the sentinel lymph node, a pen can be used to mark the corresponding location on the patient's body surface through the through-hole, as shown in FIG. 2 and described below. Scales 104 are marked on the bowl wall 103 from the bowl bottom end 101 to the bowl opening end 102, wherein zero scale lines are located at the bowl bottom end 101, and the scales 104 are used for measuring the depth of sentinel lymph nodes (the distance between the sentinel lymph nodes and the body surface in a natural state). It is obvious to those skilled in the art that the shape of the bowl-shaped body 1 is not limited by the attached drawings, and those skilled in the art can make appropriate changes to the shape of the bowl-shaped body 1 as long as the technical problems described above can be solved. The bowl-shaped body 1 can be made in different sizes so as to adapt to patients with different body sizes.
In a preferred embodiment, the bowl-shaped body 1 is formed in one step by using an inorganic transparent material, an organic transparent material or a composite transparent material. The inorganic transparent material can be inorganic glass, the organic transparent material can be organic glass, and the composite transparent material can be transparent glass fiber reinforced plastic.
In a preferred embodiment, the bowl-like body has a range of 0-5 cm. The diameter of the through hole is 1-2 cm. The diameter of the bowl mouth at the bowl mouth end is 5-10 cm. However, for those skilled in the art, the above numerical limitations should not limit the scope of the present invention, which is only a preferred embodiment of the present invention. Those skilled in the art can make modifications as needed, as long as they can solve the technical problems described above.
In a preferred embodiment, the scale 104 may be marked on the inner or outer wall of the bowl wall 103. Moreover, the scale 104 marked on the bowl wall 103 should not correspond to the arc length of the bowl wall 103, but should correspond to the depth of the center of the bowl-shaped body 1 (the scale 104 is schematically shown in the drawing for clarity of display, and such a corresponding relationship is not shown), so that no measurement error occurs.
Fig. 2 is a reference diagram of the state of use of the axillary sentinel lymph node location and depth measurement device before breast cancer operation of the present invention. As shown in fig. 2, when using the device of the present invention, first, the patient takes the supine position, the affected upper limb suspends in midair, the subcutaneous tissue around the affected mammary areola is injected with fluorescent developer (such as indocyanine green, etc.), and after waiting for 15min, the lymphatic vessel and sentinel lymph node are developed by the fluorescent detector. The detection process is pressed above-mentioned device bottom outside patient's mammary gland in region, axillary tail portion and armpit department, presses the in-process and causes that lymphatic vessel and lymph gland top skin and subcutaneous tissue receive extrusion back deformation, whole thickness attenuation to increase fluorescence penetrability, improve and detect the sensitivity. The specific operation process is as follows: in the detection process of the fluorescence detector, the probe moves outwards and upwards along the fluorescence development lymphatic vessel from the injection point of the nipple areola area (the probe is about 15cm away from the skin and does not contact the skin) to the point where the fluorescence is gradually weakened or disappears, the area and the surrounding tissues are extruded by the device until the fluorescence is developed again, a surgical incision marker pen is used for marking the body surface through the bottom opening of the device, and meanwhile, the depth is recorded along the side wall of the device (as shown in figure 2, the dotted line represents the position of the extruded body surface, and the reading of the scale where the dotted line passes is the depth of the sentinel lymph node 2). Repeating the steps until reaching the armpit, detecting the position where the accessible fluorescence intensity is obviously enhanced compared with the former position, marking the position of the sentinel lymph node, and measuring the depth.
Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
