Problems solved by technology

[0003] However, in the case of patients with difficult surgical puncture, especially for medical staff who are relatively inexperienced in surgery, the initial puncture may not reach the surgical target, and the puncture position needs to be adjusted again to ensure that the surgery is carried out at the precise surgical target. In this way, the puncture path needs to be adjusted. In this case, since the changed puncture path does not inject anesthesia, it will greatly increase the pain of the patient and increase the surgical pressure of the medical staff, which will lead to prolonged operation time, increased surgical risk, and even affect Effect of surgery
[0004] In addition, due to the patient's own blood vessel problems, multiple punctures may fail to reach the target blood vessel, which will also increase the pain of the patient and increase the pressure on the medical staff

Abstract

The invention provides a puncture needle. The puncture needle is characterized by comprising a puncture needle body, a needle body which contains a needle tip puncturing the skin of a human body and extends from the needle tip and an anesthetic layer which is at least applied to the needle tip. When the needle tip of the puncture needle makes contact with the skin of the human body, the anestheticlayer can release anesthetics to conduct local anaesthesia on the punctured portion of the human body; in this way, pain of the human body in the puncturing process can be reduced, and meanwhile theoperation pressure of medical staff can be lowered.

Description

technical field [0001] The invention relates to a medical appliance, in particular to a puncture needle. Background technique [0002] At present, interventional ultrasound has become an important branch of ultrasound medicine. Various ultrasonic puncture probes and puncture racks attached to the probes are the tools of interventional ultrasound. In the process of ultrasonic intervention, various ultrasonic puncture probes and extracorporeal puncture racks attached to the probes and intracavitary breathers are tools for interventional ultrasound. developed in response to treatment needs. In clinical use, a puncture frame is generally installed on the ultrasonic probe, and then the puncture needle is fixed through the puncture frame, and the target tissue in the human body is obtained through the puncture needle, or medical agents are injected into the patient's body through the puncture needle. Its main function is to complete various operations such as biopsy, fluid extra...
