Description
Technical field
The utility model relates to a kind of medical instruments field, in particular to a kind of puncture cutter head, biopsy rotary cutting apparatus and true
Sky auxiliary mammary gland sample biopsy and biopsy system.
Background technique
Common biopsy includes biopsy rotary cutting apparatus.The biopsy rotary cutting apparatus has casing and tissue cutting mechanism, the set
Pipe is arranged to sample recess and sample of tissue chamber.In biopsy treatment process, vacuum auxiliary device can be used to help
It helps and group is woven through sample groove sucking sampling chamber.One of biopsy device for vacuum aided biopsy rotary cutting apparatus benefit
With rotation and linear movement of the cutter head relative to sample groove is punctured, sample of tissue chamber is inhaled into across sample groove to cut off
Indoor tissue applies vacuum to organize to be delivered to sample collection device from sampling chamber.Such processing is repeated, until
Obtain the desired amount of tissue.
The puncture cutter head of biopsy rotary cutting apparatus, it is widely used in minimally invasive surgery puncturing operation, firstly, using stab knife
Head may insure that operation wound is small, does not need suture needle, can meet diagnosis and treatment requirement, moreover it is possible to ensure the beauty in shape, especially
Some breast or face etc., the surface of a wound is small to heal well, leaves the advantages that scar is small, and damage is small, recovery is fast, therefore is more susceptible to most of
The welcome of female friends.And vacuum is defeated helps the biopsy of mammary gland sample and rotary-cut is the most effective side currently used for breast biopsy procedure
One of formula needs to carry out mammary gland suspicious lesions to repeat cutting, to obtain the histological specimen of enough mammary gland, in order to breast cancer
Early detection and diagnosis, while the minimally invasive excision of mammary gland benign tumor can also be carried out.Vacuum common at present is defeated to help mammary gland
Sample biopsy and biopsy system include vacuum aided breast biopsy and rotary cutting apparatus, can carry out repeating cutting to mammary gland suspicious lesions
Sampling is obtained the histological specimen of mammary gland by vacuum suction, is stored in sample collection device, provides for the diagnosis of breast cancer
Sample.
Zou Xiao is worn application No. is 201420262643.9 breast lump rotary cutting apparatus, including locating support and puncturing head
