An anesthesia deep vein puncture needle adjusting and fixing bracket

Abstract

The invention relates to the technical field of puncture needle brackets, in particular to a deep vein puncture needle adjustment and fixing bracket for anesthesia, comprising a rectangular frame, two U-shaped frames are symmetrically fixed on both sides of the rectangular frame, and both U-shaped frames are bound and fixed inside There are binding straps, the two sides of the rectangular frame are provided with a lateral tensioning mechanism for tensioning the skin, and two support rods are symmetrically connected on the top surface of the rectangular frame. There is a semicircular guide ring, both ends of the guide ring are fixed on the top surface of the rectangular frame, and an elastic positioning mechanism for temporarily fixing the support rod on the guide ring is arranged inside the support rod; The mechanism tensions the skin at the puncture site to make the loose skin tight, which is helpful for doctors to see the meridians at the puncture site, facilitates puncture, and stably clamps and fixes the needle tube without manual support for the needle tube, which is conducive to puncture operate.

Description

technical field [0001] The invention relates to the field of puncture needle brackets, in particular to a deep vein puncture needle adjustment and fixing bracket for anesthesia. Background technique [0002] Puncture, a commonly used surgical term in medicine, is a diagnosis and treatment technique in which a puncture needle is inserted into a body cavity to extract secretions for testing, inject gas or contrast agent into the body cavity for contrast examination, or inject drugs into the body cavity. [0003] In the prior art, some invention patents related to puncture needle brackets are disclosed, and the Chinese patent with the application number of 202022025163.9 discloses a fixing device for puncture in anesthesiology department, including a bracket on which two first fixing shells and Two second fixed shells, and the two first fixed shells and the second fixed shell are respectively symmetrically installed on the upper surface of the bracket, a first moving rod is sli...

Problems solved by technology

[0004] In the prior art, when performing puncture, the puncture is mostly performed manually. The doctor manually operates for a long time, and the arm is prone to shaking, resulting in inaccurate puncture positions. There are also puncture needle supports in the prior art, but the existing supports It is bulky, fixed on the patient's body, and difficult to adjust during puncture. In view of this, we propose an adjustable fixed bracket for deep vein puncture needles for anesthesia
