Breast cancer sentinel lymph node body surface positioning pasting film and positioning set

Abstract

The invention discloses a breast cancer sentinel lymph node body surface positioning pasting film and a positioning set, and particularly relates to the technical field of medical instruments. According to the breast cancer sentinel lymph node body surface positioning pasting film and the positioning set, fixing pastes, grids, an application paste and an anesthesia paste are designed, the application paste is square, the grids with the marks are arranged on the left side and the upper side of the application paste, the grids are made of developing materials, the anesthesia paste is connected to the lower left corner of the application paste, and the fixing pastes are connected to the four sides of the application paste; compared with the prior art, the sentinel lymph node focus of the patient is positioned after shooting is completed, namely, the sentinel lymph node of the patient can be found through comparison according to the shot optical film and is accurately determined, dislocation during biopsy is reduced during surgical treatment, and surgical trauma is relieved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a breast cancer sentinel lymph node body surface positioning film and a positioning suit. Background technique [0002] At present, CT lymphoscintigraphy (CT-LG) and nuclide sentinel lymph node imaging techniques all require the injection of contrast medium around the breast tumor or subcutaneously in the areola. In order to avoid the local pain caused by the increased volume and tension of the contrast medium during subcutaneous injection, a certain dose of anesthetic is generally injected subcutaneously before the contrast medium injection. [0003] Sentinel lymph nodes can be identified by CT lymphoscintigraphy (CT-LG) or nuclear medicine images, but to determine their nature, sentinel lymph nodes need to be removed by sentinel lymph node biopsy and sent for pathological examination. This requires marking and positioning the sentinel lymph nodes identified on the imag...

AI Technical Summary

Problems solved by technology

[0005] 1. However, because many hospitals, especially grass-roots hospitals, are not equipped with CT laser guidance systems, it is difficult for these hospitals to carry out CT-LG examinations for breast cancer patients

[0006] 2. After the filming is completed, it is necessary to mark the body surface of the patient's lesion, and it is necessary to find the patient's sentinel lymph node in comparison with the optical film taken, and there are large errors

Once the biopsy is misplaced, it is necessary to expand the scope of surgery to find the sentinel lymph node, which will increase the surgical trauma to the patient

[0007] 3. Injection anesthesia is required before the biopsy. Patients will also experience varying degrees of pain when receiving subcutaneous injection of anesthetics, which will affect the biopsy puncture. This pain may increase the patient's nervousness and anxiety, thereby affecting lymphatic imaging normal progress

[0008] 4. The current positioning grating is not well fixed when the patient is shooting medical films, especially the position of the sentinel lymph node is special. Once the patient's body shakes, it will affect the later marking, and the grating has no area recognition. Medical staff are confirming the lesion. location is more difficult
