A multi-mode mammography target and a special device for releasing the target

Abstract

The invention discloses a multimode mammary gland developing target and a dedicated device for releasing the target. The target at least comprises a metal target body and a coating covering the metal target body, wherein the coating is made of genipin and I-type collagen. The dedicated device comprises a guide trocar pin and a target releasing device, wherein the metal material of the metal target performs the function of ultrasonography and molybdenum target image identification; the coating performs the functions of optical identification and acoustic identification. The multimode mammary gland developing target and the dedicated device are used for developing under various imaging modes or an optical mode, such as molybdenum target tomography, ultrasonic tomography, MRI, DBT (Digital Breast Tomography), optical tomography, and Photoacoutic Tomography; the metal target body and the coating are combined to form the mammary gland target which is macroscopic in the imaging technology and an operation and made of a composite material, so that convenience is brought for countercheck and management of a mammary gland focus, and accurate positioning before and in the operation.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a target for breast anesthesia injection, biopsy and development and a special device for releasing the target. Background technique [0002] Breast cancer screening projects are being popularized all over the world, especially in China, a country with a large population in the world. Combining high-frequency ultrasound, digital mammography, high-field strength MRI (Magnetic Resonance Imaging), and the newly emerging DBT (Digital Breast Tomography), photoacoustic imaging (Photoacoutic Tomography), the rapid development and application of these modern imaging medical technologies have made great progress in the diagnosis and treatment of breast cancer. At present, neoadjuvant chemotherapy regimens for larger lesions and early diagnosis and management of non-palpable small lesions (diameter <15 mm) are the focus and hotspots of breast cancer prevention and treatment research.

Problems solved by technology

In clinical applications, implanted targets have high technological content, all rely on imports, and the price is very high: for example, the Bard brand imported single-mode (single imaging technology) metal target and release integrated device for molybdenum target, the single price is about 800 yuan, for one time Consumables, high cost; a type of breast implant target disclosed in US Patent US6356782B1, the target has a specific shape, and the target component is a bioabsorbable and degradable substance. Such a target has complex design, fine manufacturing process, and high entry barriers , the price is as expensive as thousands of yuan (998USAD / piece), which is unbearable for patients with breast disease; and the target is only identified by images, and can only be traced and positioned under a variety of imaging methods; Orange-orange breast tissue is often difficult to identify with the naked eye during surgery, and a colorless target with a similar color can be found, especially after neoadjuvant chemotherapy, the lesion basically disappears under the naked eye
