Guiding and positioning device for mammary gland puncture

Abstract

The invention relates to the technical field of medical instruments, in particular to a guiding and positioning device for mammary gland puncture. The guiding and positioning device comprises a negative pressure cup body, an ultrasonic probe and a puncture needle body, the left side and the right side of the negative pressure cup body are fixedly connected with a first binding band and a second binding band respectively, and the surface of one side of the first binding band is sewn with a soft-face hook-and-loop fastener; the negative pressure suction cup can be bound to the body of a patient,the negative pressure suction cup is not prone to loosening or falling off, meanwhile, the puncture speed of the puncture needle can be regulated and controlled, convenience is brought to puncture operation of medical staff, and the problems that at present, in the breast lump diagnosis process, only the negative pressure suction cup is adopted for fixing, when the negative pressure suction cup leaks air, the negative pressure suction cup is loosened and even falls off, the puncture needle inclines or falls off, and when medical staff conduct puncture, once the medical staff exert too much force, the puncture needle is too high in speed, and then huge pain is brought to a patient can be solved.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a guiding and positioning device for breast puncture. Background technique [0002] With the rapid development of social economy, the incidence of breast cancer is getting higher and higher. Breast cancer is not an important organ to maintain human life activities. Breast cancer in situ is not fatal, but because breast cancer cells lose the characteristics of normal cells, cells The connection between them is loose and easy to fall off. Once the cancer cells fall off, the free cancer cells can spread throughout the body with the blood or lymph, forming metastasis and life-threatening. At present, breast cancer has become a common tumor that threatens women's physical and mental health. For breast pathological tissue Examination is a necessary means of examination to prevent breast cancer. [0003] Breast lumps are a common manifestation of breast disease in women. A clea...

AI Technical Summary

Problems solved by technology

At present, during biopsy, negative pressure suction cups are usually used. The negative pressure suction cups suck the breast into the cup body for fixation through negative pressure, which is convenient for medical staff to perform puncture operations. However, only negative pressure suction cups are used for fixation. The unexpected air leakage of the pressure suction cup will cause the negative pressure suction cup to loosen or even fall off, causing the puncture needle to be skewed or fall off, which poses a safety hazard, and most of the medical staff directly hold the puncture needle by hand when performing the puncture. Puncture, once excessive force is used, the speed of the puncture needle will be too fast, which will not only bring great pain to the patient, but also make it inconvenient for the medical staff to control the puncture depth of the puncture needle. It is tied to the patient's body, and the negative pressure suction cup is not easy to loosen or fall off. At the same time, the puncture speed of the puncture needle can be adjusted, and it is convenient for medical staff to use the guiding and positioning device for breast puncture.
