Description

Body surface marking system for breast cancer primary focus

Technical Field

The utility model belongs to the field of medical instruments, and particularly relates to a body surface marking system for a primary focus of breast cancer.

Background

When a patient after new adjuvant therapy is operated by breast surgery, the problem of positioning the breast focus of the patient is firstly faced with the problem that the breast focus of the patient is partially relieved or completely relieved after the treatment. For good efficacy, it is generally recommended to mark the range of primary lesions in patients prior to primary treatment.

Neoadjuvant chemotherapy is a common method of breast cancer treatment, and for good efficacy, it is generally recommended to perform body surface markers of primary lesion range on patients before primary treatment, and track the changes of tumor size and morphology for a period of time (four five months) to determine the subsequent treatment regimen. Thus, accurate lesion-wide body surface markers may provide accurate guidelines for subsequent treatment and surgery by the physician.

At present, in clinical application, common focus marking methods are divided into four types: body surface text labeling, metal labeling, coordinate labeling and body membrane labeling. The four methods have advantages and disadvantages.

The body surface Wen Shenfa is marked reliably and is suitable for swelling, but a professional tattoo machine needs to be purchased, dye needs to be injected into the epidermis layer of the skin, so that the patient has pain and discomfort for invasive operation and local anesthesia, and if the patient receives new adjuvant therapy for a long time, the dye fade can occur, and the patient needs to tattoo again.

The metal marking method is accurate in positioning under the support of ultrasound, but requires professional staff and equipment to operate, and can only place metal markers at the center and boundary of a focus for punctiform marking, but cannot achieve continuous marking. If the tumor focus is irregular in shape, the marking effect is poor. After the marker is placed, the patient is subjected to conditions of pressing the breast by strong external force such as breast molybdenum target examination, and the marker can be shifted. In the treatment process, the focus changes, so the focus change condition can not be continuously recorded. When a patient is subjected to an operation, the operator may not easily determine the operation range by positioning the marker clips only, and assistance such as a guide wire is also required.

The coordinate method is to digitally record the focus by using the nipple as the origin and adopting a mathematical coordinate method, the marking point is more accurate and easy to record, but the focus edge can not be completely marked, and the marking effect is poor for the crab foot-shaped edge of the breast cancer focus.

The method can continuously mark the focus, can accurately describe the focus with irregular edges, can repeatedly mark the focus, and has good patient compliance. The area of the ruler film is large, and the marking is required to completely cover all or most of breasts, if the breasts are large and drooping, the operation is complex; in addition, the focus shape is cut out every time the mark is marked, and the mark comparison cannot be repeated on the same film. If the patient has focus and affected skin to cause the collapse, the pasting effect is poor; the focus is obviously raised on the skin, a three-dimensional shape of the film needs to be designed, and the film is difficult for new students.
