Embodiment Construction

[0020] The device according to the invention comprises a handle 2 and a needle holder member 4 adapted to receive a hollow needle 8 . The needle 8 is preferably provided within the needle holder member 4 by means of the clutch 5 . The clutch is adapted to release the needle 8 easily. For example, when the needle has successfully penetrated the sampling site and the operator is about to, for example, draw a sample into the needle (described in further detail below), the operator can, if desired, release the needle via the clutch and thus remove the handle and needle The holder member is such that only the needle is present at the sampling location, thereby facilitating subsequent manipulations with the needle. The needle 8 can be an evacuation needle (0.5 to 3mm), an aspiration needle (1.2 to 3.2mm) or a thick biopsy needle (3.2 to 6m). The needle 8 may be provided with a sealing device (not shown) to prevent harmful substances from filling the needle during insertion into th...

Abstract

The present invention relates to an arrangement for sinus evacuation and for taking a sample of bone marrow during a bone marrow aspiration procedure as well as a bone marrow biopsy procedure. By applying a longitudinal movement to the needle when the needle is penetrating the bone the penetration force is reduced which lower the risk of penetrating the posterior cortex or the second sinus wall. The arrangement further comprises stopping means that prevents the needle to penetrate deeper than to a predetermined depth. The arrangement further comprises longitudinal movement stopping means that provides for an active break of the longitudinal movement of the needle when the needle has penetrated down to the predetermined depth.

Description

technical field [0001] The present invention relates to devices for obtaining bone marrow samples and for emptying sinuses. Cell sampling is preferably performed during bone marrow aspiration as well as during bone marrow biopsy. Background technique [0002] Peripheral blood tests and other routine laboratory tests do not always provide enough information to diagnose blood disorders. In some patients, direct bone marrow microscopy is required to confirm a suspicious clinical diagnosis or to monitor the course of medical treatment. [0003] During a bone marrow examination, bone marrow material is aspirated and spread out on a glass slide, or a biopsy core of bone and marrow may be obtained. Bone marrow aspirate preparations are valuable for different cell counts and morphological assessment of individual cells, whereas biopsy procedures are preferred for e.g. estimation of bone marrow cellularity, precise determination of megakaryocyte numbers and detection of e.g. leukem...
