摘要：
A biopsy system comprises an introducer and a biopsy device. The introducer comprises a cannula and at least two leaves. The cannula comprises an ovular cross-section, an open distal end and an open proximal end. The ovular cross-section defines a lumen extending between the open distal end and the open proximal end. The ovular cross-section of the cannula includes at least two flat sides. The at least two leaves extend distally from the open distal end. At least a portion of each of the at least two leaves extend from a respective flat side of the at least two flat sides of the cannula. The biopsy device comprises a body and an elongate needle. The elongate needle extends distally from the body. The elongate needle includes an ovular cross-section defining two straight sides. The cannula of the introducer is configured to slidably receive the elongate needle of the biopsy device.
