Abstract

The invention discloses a hematology bone marrow puncture needle, which comprises a puncture needle, a positioning assembly for positioning the puncture needle, a force applying assembly installed on the positioning assembly for driving the puncture needle into a patient's body, and a device for assisting the removal of the puncture needle Auxiliary parts for bone marrow, the positioning component includes a fixing part, a connecting part installed on the fixing part for connecting the force application component, the fixing part includes a fixing plate made of hard material, a silicone sticker fixed at the bottom of the fixing plate It solves the problem that the bone puncture needle is inaccurately oriented during puncture, easily slips into the side of the ilium, cannot enter the bone marrow cavity, or penetrates into the bone marrow cavity and then passes out of the bone marrow cavity.

Description

technical field [0001] The invention relates to the technical field of medical instruments, in particular to a hematology bone marrow puncture needle. Background technique [0002] Bone marrow aspiration is a common diagnostic technique for collecting bone marrow fluid. Clinically, bone marrow aspiration is also commonly used for blood cell morphology examination, and can also be used for hematopoietic stem cell collection, culture, cytogenetic analysis, and pathogenic biology inspection. [0003] The collection tools used to collect bone marrow fluid are usually based on bone puncture needles. The commonly used bone puncture needles are not oriented accurately during puncture. The bone marrow cavity is pierced out of the bone marrow cavity; at the same time, the puncture depth cannot be precisely controlled. [0004] In view of the above problems, a Chinese patent with the notification number CN106308853A discloses a hematology bone marrow puncture needle. A non-slip rubb...
