Problems solved by technology

[0003] Renal puncture needle is a kind of puncture needle used in the process of renal puncture. However, when ultrasound is used to navigate the renal puncture needle in clinical practice, the boundary between the traditional structure of the puncture needle and the kidney and its surrounding tissues is not obvious under ultrasound, which may easily lead to ultrasound The image is blurred, which is not conducive to accurate and rapid renal puncture work for doctors

Embodiment 1

[0045] A kidney puncture needle, comprising: a puncture component 1 and a protective component 2, the designed kidney puncture needle is composed of a puncture component 1 and a protective component 2, and the protective component 2 is matched with the puncture component 1, and the protective component 2 is used for protection The puncture assembly 1, under the action of the protective assembly 2, can effectively prevent the puncture assembly 1 from being damaged and can effectively prevent the puncture assembly 1 from stabbing medical personnel or patients, so that the kidney puncture needle has better safety performance and is less likely to be damaged.

[0046]Wherein, the puncture assembly 1 is used to puncture the patient's kidney, and the puncture assembly 1 is mainly composed of a needle base 101 and a metal hollow needle 102, the inside of the needle base 101 is a hollow structure, and one end of the needle base 101 is an open structure, The other end of the needle base...

Embodiment 2

[0053] The difference between this embodiment and Embodiment 1 is that the hollow groove 106 is set as a triangular hollow groove, and the inside of the hollow groove 106 is filled with helium gas, which makes the metal hollow needle 102 contact with the kidney and its surroundings under ultrasonic waves. The tissue boundary is more obvious, making the ultrasound image clearer.

Embodiment 3

[0055] The difference between this embodiment and Embodiment 2 is that the cavity 106 is set as a diamond-shaped cavity, and the inside of the cavity 106 is filled with a lipid-based ultrasonic microbubble contrast agent CNUCA, and a lipid-based ultrasonic microbubble contrast agent CNUCA The boundary between the metal hollow needle 102 and the kidney and its surrounding tissues is more obvious under ultrasound, so that the ultrasound image is clearer.

Abstract

The invention discloses a kidney puncture needle. The kidney puncture needle comprises a puncture assembly and a protection assembly, the puncture assembly is used for puncturing the kidney of a patient, the puncture assembly comprises a needle base and a metal hollow needle, the protection assembly and the puncture assembly are arranged in a matched mode, and the protection assembly is used for protecting the puncture assembly. According to the kidney puncture needle, an empty groove is reserved in a needle tip, the empty groove is filled with air or helium or a lipid ultrasonic microbubble contrast agent CNUCA, in clinic, ultrasonic waves are utilized to conduct puncture guide on the kidney puncture needle, the air or helium or lipid ultrasonic microbubble contrast agent CNUCA enables the metal hollow needle to be obviously demarcated with the kidney and surrounding tissues under the ultrasonic waves, so that ultrasonic images are clear, medical staff in the nephrology department can be helped to judge the needle inserting condition, the medical staff can accurately and rapidly conduct kidney puncture work, therefore, the working efficiency of medical staff is effectively improved, and it can be guaranteed that the kidney of the patient is safely punctured.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a kidney puncture needle. Background technique [0002] Kidney biopsy is kidney biopsy, also known as renal biopsy. Due to the wide variety of kidney diseases and the complex etiology and pathogenesis, the clinical manifestations of many kidney diseases are not completely consistent with the histological changes of the kidneys. For example, the clinical manifestation is nephrotic syndrome, and the pathological changes can be manifested as minimal lesions, mild lesions, mild mesangial hyperplasia, membranous nephropathy, membranous proliferative nephritis, focal segmental sclerosis, etc. Development outcomes also vary widely. [0003] Renal puncture needle is a kind of puncture needle used in the process of renal puncture. However, when ultrasound is used to navigate the renal puncture needle in clinical practice, the boundary between the traditional structure of the pun...
