Problems solved by technology

[0002] When using an ultrasonic block needle, it is necessary to use ultrasound to detect the insertion position of the ultrasonic block needle. However, the existing ultrasonic block has a poor reflection effect on ultrasound, resulting in poor imaging effect, which makes the positioning of the ultrasonic block needle inaccurate.

Embodiment 1

[0023] The structural schematic diagram (section view, section line not shown) of the ultrasonic blocking needle with good developing effect in Embodiment 1 of the present invention is as follows figure 1 shown, see also figure 2 ; Including the puncture needle 1; Also includes the developing core 2 that penetrates in the puncture needle 1, and the fixing assembly 3 for fixing the developing core 2 and the puncture needle 1 together; The developing core 2 is provided with a developing chamber 4; The interior of 4 is a vacuum; the developing core 2 and the puncture needle 1 are fixed together by the fixing assembly 3, when the puncture needle 1 enters the human body, the developing core 2 enters the human body accordingly, because sound waves cannot be transmitted in a vacuum, so when using ultrasonic testing When the blocking needle is positioned, the developing core 2 provided with a developing chamber 4 with a vacuum inside can improve the developing effect of the ultrasoni...

Embodiment 2

[0031] Such as Figure 3 to Figure 5 As shown, Embodiment 2 of the present invention is basically the same as Embodiment 1, and the similarities will not be described again. The difference lies in:

[0032] Preferably, the developing core 2 is provided with a drug injection channel 10 that runs through its upper and lower surfaces; the developing chamber 4 is arranged around the drug injection channel 10; the upper end surface of the developing core 2 is in contact with the inner top surface of the fixed cover 6; Drug injection port 11; drug injection port 11 is facing the drug injection channel 10; since the developer core 2 is provided with a drug injection channel 10, when the puncture needle 1 is inserted in place, it can be injected into the human body through the drug injection port 11 and the drug injection channel 10 Medicine, without taking out the developing core 2, the operation is more convenient.

[0033] Preferably, the developing core 2 includes an inner tube 1...

Embodiment 3

[0036] Embodiment 3 of the present invention is basically the same as Embodiment 1, and the similarities will not be described again. The difference lies in:

[0037] The fixed ring 5 is a tapered ring with a small upper part and a larger lower part; it is convenient for the fixed cover 6 to be sleeved outside the fixed ring 5 .

Abstract

The invention relates to an ultrasonic retardation needle with a good developing effect. The ultrasonic retardation needle comprises a puncture needle, a developing core is arranged in the puncture needle in a penetrating manner; a fixing assembly is used for fixing the developing core and the puncture needle together; the developing core is provided with a developing cavity; the inside of the developing cavity is vacuum; the developing core and the puncture needle are fixed together through the fixing assembly, when the puncture needle enters a human body, the developing core enters the human body along with the puncture needle, and due to the fact that sound waves in vacuum cannot be conducted, when the position of the retardation needle is detected through ultrasound, the developing core provided with the developing cavity with the vacuum interior can improve the developing effect of the ultrasound blocking needle; and therefore, the positioning of the ultrasonic retardation needle is more accurate.

Description

technical field [0001] The invention relates to the technical field of ultrasonic blocking needles, and more specifically, relates to an ultrasonic blocking needle with good developing effect. Background technique [0002] When using an ultrasonic block needle, it is necessary to use ultrasound to detect the insertion position of the ultrasonic block needle. However, the existing ultrasonic block has poor reflection effect on ultrasound, resulting in poor imaging effect, which makes the positioning of the ultrasonic block needle inaccurate. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an ultrasonic blocking needle with good developing effect in view of the above-mentioned defects of the prior art. [0004] The technical solution adopted by the present invention to solve its technical problems is: [0005] Construct an ultrasonic blocking needle with good development effect, including a puncture needle; wherei...
