In use, the suction type biopsy for tumor of breast Minimally Invasive Surgery that medical worker holds the utility model samples
Device then by the tumor of breast lesion tissue of probe tube insertion patient, then unclamps thumb with thumb press piston, the
Under the action of two springs, negative pressure is generated in negative pressure cylinder, pathological tissues are attracted in probe tube, last push nut drive rod,
Nut is driven to move axially with respect to screw rod, nut drives screw rod rotation, and screw rod drives sampling cutter rotation to cut off pathological tissues.
Compared with the existing technology, the utility model is used for the beneficial of the suction type biopsy sampler of tumor of breast Minimally Invasive Surgery
Effect are as follows: (1) pressing of medical worker's one hand can be realized pathological tissues traction and cutting, another hand and can carry out stopping blooding etc. other
Operation, saves manpower；Moreover, simplifying sampling procedure, sampling efficiency is improved；(2) sampling cutter be located in sampling room and
Its rotation center and sampling room are coaxial, not only can guarantee that sampling cutter cut off pathological tissues, but also can prevent from making the organs and tissues of patient
At additional damage.
