The utility model discloses a kind of negative pressure suction type
puncture biopsy apparatus, it is related to medical instrument field.The
biopsy apparatus includes needle tube, needle core and pressure device, pressure device is detachably connected with needle tube, is fixed by clamping limiting portion.It has beneficial effect including improving
sample quality, convenient operation and improving diagnostic efficiency.Needle tube has scale outside, bottom and needle core cooperate closely.
Handle has antiskid line, connecting port and pressure device connecting
pipe are closely adhered through conical structure.Needle core surface is smooth, and needle tube is closely adhered.Pressure device can be
balloon expansion pressure pump etc., clamping limiting portion improves the stability of connecting portion.Under
image guidance, puncture is operated as needed, and sample is obtained by adjusting negative pressure.The
biopsy apparatus overcomes the problem that existing
puncture biopsy mode is difficult to balance sample efficiency and
tissue protection, and the problem of inconvenient operation, can adapt to different texture tissue, improve
sample quality and representativeness, reduce operation difficulty and risk.
