Title
(EN) Prostate biopsy needle
Abstract
(EN)
Present invention solved the problem of complications occurred during transrectal prostate biopsy, mostly infectious and bleeding complications. Thus, the prostate biopsy needle according to the invention comprising a cannula (1), a pointed stylet (2), which is mounted slidably in the cannula (1), handles (3a, 3 b) for the biopsy gun, which are located on the back side of the needle. An inner surface (4) of the cannula (1) and / or an outer surface (5) of the cannula (1) and / or a surface of the stylet (2) is coated with at least one active layer (6) comprising a biologically active agent, wherein the active layer (6) preferably forms a biodegradable structure enabling controlled release of the biologically active agent.
