摘要：
The invention relates to a device for taking aliquid bone marrow sample (aspiration) and a solid bone sample(biopsy) in the same procedure, which can replace the specialneedles used to obtain bone marrow and those used exclusivelyfor bone biopsy. The aforementioned device includes a simplemechanism employing two catches formed by grooves. In addition,the device can be easily dismantled for sterilisation andthe handle thereof is designed to facilitate puncture. Theneedle of the device is hollow and contains a guide having twosections of different diameters. The guide enables the channelof the cavity of the needle to be opened so that the bonemarrow liquid can flow therethrough and be extracted, as wellas enabling said channel to be closed so that the tissue can bepenetrated. The aim of the invention is to provide bone marrowbiopsy and aspiration methods that reduce both patient discomfortand procedure times.
