Stand type two-chamber anesthetic needle

Abstract

The invention discloses a trestle-type dual-chamber anaesthesia needle, which comprises a fixation clamp which is provided with a screw on which a nut is mounted; the nut is movably connected with a rotating shaft which is connected with a sleeve in which a sleeve lumen is provided; a mandrel is mounted in the sleeve lumen; one end of the mandrel which goes through and extends out from the sleeve is provided with a first gimbal that is connected with a second gimbal by a first connecting rod; the second gimbal is connected with a rzeppa gimbal which is connected with a fixation sleeve in which a needle handle is mounted; an installation pipe is arranged on the fixation sleeve; a neilsbed is mounted on the installation pipe; a dual-chamber combination needle body is mounted on the neilsbed; the needle body is provided with a first chamber and a second chamber; one end of the dual-chamber combination needle body is provided with an up syphon which slantwise runs through, extends out of the neilsbed and is communicated with the second chamber; a spinal needle is mounted at the lower end of the needle handle and is positioned in the first chamber. The trestle-type dual-chamber anaesthesia needle is provided with a trestle which can adjust position flexibly and facilitate doctors to operate taking the trestle as a fulcrum and position and insert needle accurately, thus accurate and quantized needle insertion operation can be realized.

Description

technical field [0001] The invention relates to a medical device, specifically a bracket-type double-chamber anesthesia needle. Background technique [0002] The existing anesthesia needles have the following defects: 1. The operation is completely dependent on the doctor's experience to insert the needle, which is difficult to operate and it is difficult to accurately quantify the needle; 2. When using it, the spinal anesthesia needle must be introduced first, and then inserted Hard outer catheters are more dangerous and can easily cause harm to patients. Contents of the invention [0003] The purpose of the present invention is to provide a bracket-type double-chamber anesthesia needle, which is equipped with a bracket, and the position of the bracket can be adjusted flexibly, which is convenient for the doctor to use the bracket as the fulcrum to operate and accurately position the needle, thereby realizing accurate and quantitative needle insertion operation ; It can ...
