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.
