Description

TECHNICAL FIELD

[0001] The utility model relates to medical auxiliary device technology, concretely relates to an anesthesia ultrasonic probe support. BACKGROUND

[0002] Puncture operation (such as nerve block puncture, vascular puncture catheterization, etc.) under the guidance of ultrasound has become a key technical means to improve the accuracy and safety of anesthesia. In such operations, the anesthesia ultrasonic probe support as an auxiliary instrument is mainly used to stably support the ultrasonic probe and accurately clamp and position the puncture needle (such as nerve stimulation needle, vascular puncture needle, etc.), so that the puncture needle can accurately enter along the ultrasonic scanning plane, and the medical staff can clearly observe the path of the puncture needle and the position of the target point, thereby improving the success rate of puncture operation.

[0003] The anesthesia ultrasonic probe support in the prior art, after achieving clamping and positioning of the puncture needle, often needs to wait for ultrasound image calibration, patient position fine adjustment or coordination with the operation process rhythm during anesthesia puncture operation. The puncture needle may be idle for a short period of time after clamping and positioning. The slight displacement of the surgical drape, the airflow disturbance when the medical staff transfers the instrument, and the like during this stage easily cause the tiny particles (such as sterile dressing fibers, tiny coating particles falling off the surface of the instrument) on the edge of the sterile area to adhere to the needle tip. In part of the peripheral nerve block operation, the support needs to be moved to adjust the ultrasonic scanning angle, and the needle tip may accidentally touch the operating bed rail (although it is disinfected, but it is not the core sterile area), the monitor lead, and the like non-sterile contact surface, thereby destroying the sterile state of the needle tip, and further increasing the risk of infection of the puncture site of the patient. Meanwhile, the needle tip of the puncture needle is sharp and has no shielding, and the hands or arms of the medical staff are easily mistaken for the needle tip when they are close to the support (such as arranging the ultrasonic probe wire bundle, adjusting the puncture angle parameter, and transferring other anesthesia instruments). Even if the strict aseptic operation specification is followed, the risk of mistaken touch during such close collaborative operation cannot be completely avoided, and the professional exposure is easily caused, which has the safety hidden danger of blood-borne pathogens and reduces the safety of the medical staff during the puncture operation process.
