Technical Field
The invention relates to the technical field of biopsy sampling, in particular to an application method of a biopsy device with a focus marker imbedding function.
Background
With advances in imaging technology, there is an increasing number of early breast cancers that are negative for clinical palpation, how are "minimally effective" to locate and resect? How are the same lesion to be marked for subsequent follow-up and surgical treatment, with different imaging techniques to perform and classify the lesion? How does a primary tumor lesion or metastatic lymph node change in size morphology after neoadjuvant chemotherapy to achieve complete pathological remission, preoperative imaging assessment and follow-up? How do intraoperative anatomic and histopathological assessment of cutting edges or precise excision of metastatic lymph nodes? The breast focus positioning mark clamp is called as a breast Marker for short, and is expected to solve the series of dilemmas.
The biopsy needle function and Marker placement instrument adopted in clinic at present are two independent instruments, and the clinical requirement that the Marker is placed within 10mm of the focus bulls-eye position is higher than the surgical operation requirement of re-placement of the Marker after biopsy; firstly, puncture again after biopsy cutting sampling is completed to find a focus position to be placed into a Marker, so that secondary injury is caused to a patient; secondly, because the puncture sampling part is displaced due to the accordion effect, the Marker is punctured again, and the original focus bullion is difficult to accurately find;
therefore, in order to solve the technical problems, the invention provides an application method of a biopsy device with a focus Marker embedding function, wherein biopsy sampling and Marker embedding are completed simultaneously in a process of puncturing a patient once, and a biopsy needle at a focus sampling position can be accurately embedded by a Marker.
