A bone marrow puncture extraction device with a positioning frame

Abstract

The invention relates to a bone marrow aspiration extraction device with a positioning frame. The device comprises a bone marrow aspiration extraction needle and an aspiration positioning frame for auxiliary positioning in an aspiration process, A bone marrow aspiration needle includes a cylindrical housing, a aspiration needle, needle core assembly, Anesthesia needle and pulp withdrawal needle, alancet core assembly include a lancet core body and a lancet control handle, an anesthetic needle comprise an anesthetic syringe, a piston and a push-pull rod arranged in the anesthetic syringe. Thepulp extracting needle comprises a pulp extracting needle barrel, a piston arranged in the pulp extracting needle barrel and a push-pull rod; the anesthetic needle barrel and the pulp extracting needle barrel are respectively passed through the other two channels of the rotary cover; and the aspiration positioning frame comprises a rectangular frame, a positioning block, an aspiration block, a longitudinal positioning strip, a transverse positioning strip and four legs. The bone marrow aspiration needle not only can solve the problem of reducing the aspiration times, but also is provided witha positioning frame, which is convenient for medical personnel to carry out aspiration and bone marrow fluid extraction operation.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a bone marrow puncture extraction device with a positioning frame. Background technique [0002] A conventional bone marrow puncture needle is similar to an ordinary medical puncture needle, and its main feature is that it includes a needle seat for connecting with, for example, a syringe and a tubular needle body. The needle seat and the needle body are fixedly connected, and the cavity in the needle seat is used for communication between the needle body and, for example, the needle barrel. During bone marrow puncture, it is necessary to use an injection needle to perform anesthesia puncture at the puncture point first, and then use a bone marrow puncture needle to puncture and extract bone marrow at the same site. The anesthesia puncture and marrow extraction puncture are performed separately, and the number of punctures increases, which increases the pain of the patien...
