Benefits of technology

This patent text describes improvements in techniques for collecting biological tissue onto a sample holder, such as from a biopsy needle. These improvements can reduce damage to the tissue, maintain its integrity and orientation, and even increase the likelihood of detecting disease. Overall, this technology can enable more accurate and precise diagnostic procedures, reducing treatment time, patient discomfort, and cost.

Problems solved by technology

However, the current biopsy needles and tissue handling techniques are inherently limited by the shortage of devices and methods that may deliver the required spatial resolution, tissue harvesting efficiency and adequacy of post-biopsy tissue handling, for optimized histological review.
As a result, all information about the original location from where a particular sample was taken in the prostate is lost.
Yet, even employing an ideal procedure with currently available devices and tools would still be deficient.
Yet, with the current needles and tissue handling techniques, even such an ideal procedure may lead to a spatial location uncertainty of more than 20 mm.
However, Z-axis inaccuracy of the sample original location is dominated not by the needle spatial recognition available through such techniques, but rather by inherent uncertainty resulting from the available biopsy needles designs and the tissue core handling as is explained below.

Description

FIELD OF THE INVENTION[0001]The invention, in some embodiments, relates to the field of handling biological tissues, and more particularly, but not exclusively, to devices and methods intended for handling biological tissues that are taken with a biopsy needle.BACKGROUND OF THE INVENTION[0002]Core biopsy is a routine procedure used to obtain a sample of a biological tissue from a live organ for a laboratory examination. FIGS. 1A-1D depict schematically a core biopsy needle 10 used for taking core biopsy samples. Core biopsy needle 10 comprises a mandrel 12 and a Cannula 14. Mandrel 12 is an elongated solid needle having a distal tip 16 at the end of needle 10 and a notch 18 adjacent to distal tip 16. Notch 18 is an interior shaft recess, used for receiving the tissue sample. Cannula 14 is a sleeve exterior to mandrel 12 and is configured for sliding over mandrel 12.[0003]During a core biopsy procedure distal tip 16 of core biopsy needle 10 is brought up to a few millimeters from a r...
