An ultrasonic fixation frame for ultrasound-guided cervical nerve block and vascular puncture

Abstract

The invention discloses an ultrasonic fixing rack for ultrasound-guided neck nerve block and vascular puncture. The fixing rack comprises a bottom mold, wherein the bottom mold is of an arc-shaped structure; an open window, which penetrates the bottom mold, is formed in the bottom mold; a pair of clamping plates for clamping an ultrasonic probe are assembled at the upper side of the open window in a movable mode; a guider, which can slide on one of the clamping plates, is arranged on the clamping plate; the guider comprises a needle cover with two ends going through; and the a puncture needle penetrates the needle cover of the guider and conducts a puncture operation when the ultrasonic probe is clamped between the clamping plates. According to the scheme, a good auxiliary appliance is provided for neck nerve block and vascular puncture; and the auxiliary appliance is conducive to the improvement of a puncture success rate, the reduction of surgical risks and the improvement of an operation efficiency.

Description

technical field [0001] The invention relates to a puncture positioning and guiding device, in particular to an ultrasonic fixation frame for ultrasonically guiding cervical nerve block and blood vessel puncture. Background technique [0002] In recent years, ultrasound has been widely used in regional blockade. Using ultrasound guidance in regional blockade, the nerve structure and surrounding blood vessels, muscles, bones and visceral structures can be clearly seen; a puncture needle can be provided during the needle insertion process. Real-time images of the progress, so that the direction and depth of the needle can be adjusted at any time while the needle is being inserted, so as to better approach the target structure; the diffusion of the drug solution can be seen during the injection, and the unintentional intravascular injection and the unintentional intraneural injection can be identified in addition, there is evidence that the use of ultrasound guidance reduces the...

Problems solved by technology

However, in the operation of the neck, due to the large number of blood vessels and nerves in the neck, it is difficult to insert the needle, and the operating space is limited, which brings higher requirements to the doctor's operation.

During the puncture, the doctor needs to hold the probe with one hand and observe the screen, and perform the puncture operation with the other hand, and correct the puncture direction and position under the guidance of the image, and cooperate with the injection process. brings problems
