Description

Positioning structure for breast focus puncture

Technical Field

The application relates to the technical field of mammary gland detection and positioning, in particular to a positioning structure for mammary gland lesion puncture.

Background

In order to prevent and alleviate the harm of breast diseases to female health, accurate diagnosis and early treatment of breast diseases are required in an accurate examination manner. At present, three modes of mammary gland disease examination mainly comprise digital X-ray mammary gland photography, ultrasonic mammary gland examination and magnetic resonance mammary gland imaging, the mammary gland X-ray photography can find asymptomatic patients or tumors negative in clinical preliminary diagnosis, and the method has the advantages of simple operation, low examination cost, no wound and the like, and is the first-choice method for the mammary gland examination.

The micro focus in mammary gland can be detected as early as possible, and can be treated as early as possible, so as to prolong female life. According to authority survey, the breast lesion is found on the scale of less than 10mm, and the life of a patient can be prolonged by 5-10 years. However, microscopic lesions are difficult to diagnose accurately by imaging. Clinically, a fine needle aspiration biopsy or a guide wire three-dimensional positioning aspiration biopsy is adopted to diagnose the tiny focus.

Relevant patents that can be searched for approximations are:

chinese patent CN 102860834B-a positioning system for breast lesion puncture points, published as: 20140604, in the patent, firstly, mammary images shot by an X-ray digital mammary machine dome at two different angles are obtained, a focus projection light cone is established to generate a puncture guide body model, then, a parallel detector plane is used for cutting the maximum section of the guide body, and a point far away from the edge on the maximum section is taken as a puncture point. This application is theoretically possible, but during the compression of the gland, the patient feels discomfort, and there are cases where the patient's body moves slightly, resulting in displacement of the lesion. In addition, the displacement of the focus can be caused by the shaking of the machine in the movement process of the stadium. Therefore, the acquired anchor point may have a deviation.

The breast biopsy puncture technology provides great help for accurate diagnosis of clinicians, and particularly has high accuracy for puncturing the focus of more than 10 mm. However, since there is a case where tissues are superimposed in the two-dimensional breast image, it is difficult to accurately locate the position of the lesion. The condition that the puncture point is not in the focus appears clinically. For a tiny lesion, the distance between the puncture point and the edge of the lesion is too short, and the accuracy of a diagnosis result is affected by too little lesion tissue obtained by puncture. The existing positioning structure for the puncture of the breast lesion is complex in manufacturing, and the breast to be detected needs to be exposed for multiple times, so that unnecessary radiation damage is easily brought to a patient.
