Improved bone decompression needle

Abstract

The invention discloses an improved bone decompression needle. The needle comprises a needle rod with a needle tip and a handle connected with the needle rod, wherein the middle part of the handle is connected with the rear end of the needle rod in a T shape; the needle tip is a three-edge needle tip; a needle sleeve is arranged on the outer side of the needle rod in a sleeving manner; the front part of the needle sleeve is provided with a self-tapping thread; the tail end of the needle sleeve is provided with a joint connected with a syringe; a connecting cap is arranged at the joint for connecting the handle; since the needle tip is three-edge, the needle tip can be easily pierced into bone; the self-tapping thread of the needle cap on the rear side of the needle tip can enhance the propelling force of the needle tip to smoothly drill the bone during rotation; clockwise rotation is used for insertion of the needle, and anticlockwise rotation is used for withdrawing of the needle; a casing is arranged on the outer side of the improved bone decompression needle, so that fluid extraction can be performed by only withdrawing a needle core, remaining the casing in the bone and under the skin immovable and connecting a 20ml syringe with the joint on the tail part of the casing after the bone decompression needle is inserted into the bone; thus the defects of time consuming and labor consuming due to difficulty in discovery of a needle hole of a bone face after the bone decompression needle is withdrawn from the bone hole and the skin are overcome.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to an improved bone decompression needle. Background technique [0002] Exploration of the treatment of bone hypertension: Xu Zhenhua and other scholars first proposed the concept of "bone hypertension" in the early 1990s. It is pointed out that intraosseous hypertension is a disease characterized by intraosseous high pressure as a pathophysiological change, which manifests as intractable pain in local bones and joints. It often appears in the early stage of certain diseases and has the characteristics of typical rest pain or night pain. The proposal of intraosseous hypertension has opened up a new way for the clinical diagnosis and treatment of bone and joint pain. Therefore, if the occurrence and development of intraosseous hypertension can be prevented, it will have an important impact on the treatment and prognosis of such diseases. The main methods of prevention and t...

Problems solved by technology

[0010] During the operation of the traditional decompression needle, after the bone decompression needle exits the bone surface and skin, it is difficult to find the needle hole on the bone surface when using a 20ml syringe to draw liquid, which brings inconvenience to the operator.
