    • A biopsy punch for removing a biopsy sample from a biopsy area of a patient includes a handle and a tubular blade. The handle is adapted for gripping by a user. The tubular blade extends around a longitudinal axis and has first and second longitudinally spaced blade ends separated by a blade body. The tubular blade is operatively coupled to the handle, has a cutting edge at the second blade end, has a plurality of openings located in the blade body and allowing the user to view the biopsy area for positioning the cutting edge in the biopsy area, and has at least one retainer prong extending toward the longitudinal axis and operative to engage the severed sample to assist in retaining the severed sample in the blade body. The tubular blade is adapted to sever at least a portion of the biopsy sample from the biopsy area and retain the severed sample in the blade body. A method of using the biopsy punch is also described.
    • 用于从患者的活组织检查区域去除活检样本的活检穿孔器包括手柄和管状刀片。 手柄适于用户抓握。 管状刀片围绕纵向轴线延伸并且具有由刀片主体分开的第一和第二纵向间隔开的刀片端部。 管状刀片可操作地联接到手柄,在第二刀片端具有切割边缘,具有位于刀片主体中的多个开口,并允许使用者观察活检区域以将切割边缘定位在活检区域中,以及 具有至少一个朝向纵向轴线延伸的保持器插脚,并且可操作地接合切断的样品以帮助将切断的样品保持在叶片体中。 管状刀片适于从活检区域切断活检样本的至少一部分并将切断的样品保持在叶片体内。 还描述了使用活检穿刺的方法。
