BONE BIOPSY AND BONE MARROW ASPIRATION DEVICE

摘要

The invention relates to a device for taking a liquid bone marrow sample (aspiration) and a solid bone sample (biopsy) in the same procedure, which can replace the special needles used to obtain bone marrow and those used exclusively for bone biopsy. The aforementioned device includes a simple mechanism employing two catches formed by grooves. In addition, the device can be easily dismantled for sterilisation and the handle thereof is designed to facilitate puncture. The needle of the device is hollow and contains a guide having two sections of different diameters. The guide enables the channel of the cavity of the needle to be opened so that the bone marrow liquid can flow therethrough and be extracted, as well as enabling said channel to be closed so that the tissue can be penetrated. The aim of the invention is to provide bone marrow biopsy and aspiration methods that reduce both patient discomfort and procedure times.
