Abstract

The invention discloses a bone marrow puncture needle for hematology department, including a puncture needle, a positioning assembly for positioning a puncture needle, a force applying assembly mounted on the positioning assembly for driving a puncture needle into a patient and an auxiliary member for assisting the puncture needle in removing bone marrow. The positioning assembly includes a fixture, the fixing piece comprises a fixing plate made of hard material and a silica gel bonding part fixed on the bottom of the fixing plate, which solves the problems that the bone puncture needle is inaccurate in orientation when puncturing, is easy to slide into the iliac bone side, can not enter the bone marrow cavity, or penetrates into the bone marrow cavity and then penetrates 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...
