Nerve block anesthesia needle positioning apparatus

Abstract

The invention discloses a nerve block anesthesia needle positioning apparatus. The nerve block anesthesia needle positioning apparatus comprises a base; a horizontal movement device is arranged on the top surface of the base; a vertical movement device is arranged on the top surface of the horizontal movement device; a horizontal connection rod is fixedly connected with one side of the vertical movement device; an installation plate is fixedly mounted on one side of the connection rod; a spherical through groove is formed on the front of the installation plate; a concentric sphere is arranged inside the spherical through groove; and the sphere is only capable of rotating along the center of the sphere in the spherical through groove. Being arranged with the sphere, the nerve block anesthesia needle positioning apparatus is capable of driving an anesthesia needle to rotate along with rotation of the sphere in the spherical through groove, thereby having position of the tip of the anesthesia needle adjusted; and thus, convenient adjustment is allowed so as to improve flexibility of the tip of the anesthesia needle. Moreover, the nerve block anesthesia needle positioning apparatus is capable of keeping the tip of the anesthesia needle at a relatively good position so as to facilitate injection of an anesthetic. In addition, the tip of the anesthesia needle is driven to be inserted into peripheral nerve trunk of a patient along with rotation of a first bolt, so that, deviation of the tip of the anesthesia needle upon insertion is avoided so as to make the insertion point more accurate.

Description

technical field [0001] The invention belongs to the field of fixing devices, in particular to a nerve block anesthesia needle positioning device. Background technique [0002] When the existing nerve block anesthesia needle positioning device is in use, the anesthesia needle and the fixing device are fixedly connected, the anesthesia needle can only be adjusted up and down and left and right, the flexibility is low, and the needle cannot be placed at a better puncture point , it is not convenient to adjust the anesthesia needle, and the needle is prone to shake when it is inserted, causing the insertion point to deviate. Inconvenient to use. Contents of the invention [0003] The invention provides a nerve block anesthesia needle positioning device to solve the defects in the prior art. [0004] The present invention is achieved through the following technical solutions: [0005] A nerve block anesthesia needle positioning device, comprising a base, a horizontal movemen...
