Abstract

The invention discloses a medical puncture needle for bone marrow biopsy. The medical puncture needle comprises a handle (1), movable sleeves (2), a tapered sleeve (3) and a spiral needle head (4); the movable sleeves (2) and the tapered sleeve (3) sleeve a head of the handle (1); a spiral wire is arranged at the point of the puncture needle, on the spiral needle head (4); a needle core (5) is arranged in the center of the handle (1); the movable sleeves (2) are of different length; the tapered sleeve (3) and the movable sleeves are fixedly connected with the handle (1); the spiral needle head (4) is arranged in the tapered sleeve (3) to form a tool for acquiring bone and marrow; a plurality of lengthways-arranged longitudinal edges (101) are arranged on the handle (1); the handle (1) is spindle-shaped; an internal electrode wrapped with an insulating substance is mounted in the spiral needle head (4); the movable sleeves (2) and the tapered sleeve (3) form an external electrode; the internal electrode and the external electrode are connected to an external puncture indicating instrument (6) through a socket in the handle (1). The puncture needle is safe and reliable to operate and high in puncturing efficiency and relieves the pain of a patient.

Description

technical field [0001] The invention relates to a medical device, in particular to a medical bone marrow biopsy needle. Background technique [0002] Currently, the clinical diagnosis of many hematological tumors and other diseases requires bone marrow biopsy. A bone marrow biopsy needle is a necessary instrument for performing a bone marrow biopsy. Existing technology generally first injects local anesthetic at the patient's biopsy site with a 5ml syringe, then pulls out the anesthesia syringe, and then uses a bone marrow biopsy needle to insert a needle at the same site to get bone marrow tissue. On the one hand, there are many steps in the whole operation process, and the operation time is long. On the other hand, due to the difference in the angle of insertion of the bone marrow biopsy needle and the degree of skin tightness after the bone marrow biopsy needle enters the skin, it is often possible to deviate from the previous point of skin and periosteum anesthesia, thu...
