Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. Note that the following description of the embodiments is merely an example of the nature, and the present invention is not intended to limit the application or the use thereof, and the present invention is not limited to the following embodiments.
Examples
As shown in figure 1, the multi-cavity puncture needle based on ultrasonic guidance comprises a puncture needle body 1, wherein the puncture needle body 1 is a silver needle body or a stainless steel needle body.
a water separation cavity 2 for injecting physiological saline into tissues and separating soft tissue layers;
a nerve stimulator connecting cavity 3 for nerve electrical stimulation verification;
a liquid medicine connecting cavity 4 for injecting liquid medicine to the target position;
a pressure measuring instrument connecting cavity 5 for monitoring local pressure while injecting the liquid medicine;
the four cavities are respectively led out from the tail part of the puncture needle body 1 through independent pipelines 6, and the tail ends of the pipelines 6 are provided with connecting interfaces 7. In fig. 1, the four independent cavities are only shown schematically, and in specific implementation, the heads of the four cavities are all communicated with the needle point of the puncture needle body 1.
The utility model relates to a multicavity pjncture needle based on supersound guide's concrete use does:
when the needle is started, water is injected into the water separation cavity 2 through the connecting interface 7 communicated with the water separation cavity 2, the injected water flows to the needle point of the puncture needle body 1 through the water separation cavity 2 and flows out of the needle point to human tissues for separating soft tissue layers, and ultrasonic images can more clearly show structures such as nerves, blood vessels, tendons and the like on a puncture path by combining ultrasonic guidance in the process, so that puncture attempts are reduced, and puncture injuries are reduced;
