Ultrasonic-guided mammary gland puncture device

Abstract

The invention discloses an ultrasonic-guided mammary gland puncture device. The ultrasonic-guided mammary gland puncture device comprises an outer ring, an inner ring and a fixed disc; the outer ringand the inner ring are semicircular structures; the inner ring is composed of an upper inner ring body and a side inner ring body; furthermore, the upper inner ring body and the side inner ring body are spliced to form a semicircular structure; the periphery of the surface of the inner wall of the outer ring is fixedly connected with a fixed base; a sliding groove is arranged in the other end of the fixed base; the bottom in the sliding groove is fixedly connected with a first spring; the other end of the first spring is fixedly connected with a connecting rod; the side surface of the connecting rod is in contact connection with the side surface of the sliding groove; furthermore, the other end of the connecting rod is fixedly connected with the outer walls of the upper inner ring body andthe side inner ring body respectively; a puncture cylinder is installed between the side inner ring body and the outer ring; and the outer surface of one end of the inner side of the puncture cylinder is in contact connection with the inside of the side inner ring body. The ultrasonic-guided mammary gland puncture device disclosed by the invention has a better breast fixing effect, is more beneficial to subsequent mammary gland puncture, and can effectively reduce the pain of a patient caused by mammary gland puncture.

Description

technical field [0001] The invention relates to the field of mammary gland puncture, in particular to an ultrasound-guided mammary gland puncture device. Background technique [0002] The mammary gland is located between the superficial and deep layers of the subcutaneous superficial fascia. The superficial fascia extends into the breast tissue to form a cord-like interlobular septum. One end is connected to the pectoralis fascia, and the other end is connected to the skin, fixing the mammary glands in the subcutaneous tissue of the chest. The fibrous connective tissue that supports and holds the breast in place is called the suspensory ligaments or ligaments of Coopers. The deep superficial fascia is located on the deep side of the mammary gland, and there is loose tissue between the superficial pectoralis major fascia, which is called the posterior space of the breast. It can make the breast not only relatively fixed, but also have certain mobility on the chest wall. ...
