High-precision biopsy puncture device for nephrology department and use method of high-precision biopsy puncture device

Abstract

The invention discloses a high-precision biopsy puncture device for the nephrology department and a use method of the high-precision biopsy puncture device, and belongs to the field of kidney puncture. According to the high-precision biopsy puncture device for the nephrology department, through the arrangement of a multi-point volume shrinkage ring, before kidney puncture is carried out, under the suction effect, the part, needing to be punctured, of a patient is in close contact with the multi-point volume shrinkage ring, and when a puncture position is stressed by a puncture needle, the multi-point shrinkage ring can remarkably intercept deformation fluctuation caused by skin stress at the puncture position, the skin deformation range is narrowed, offset caused by skin elasticity during puncture of the puncture needle is reduced, accuracy during kidney puncture is remarkably improved, and the success rate of kidney puncture is increased. Meanwhile, in cooperation with the effects of the inner extending ribbons and the puncture assisting stabbing rods, the inner extending ribbons are punctured when gradually getting close to the outer extending stabbing rods, the disinfection antibacterial liquid in the inner extending ribbons overflows to the skin of the punctured position, bacterium breeding caused by sweat generated when the position makes contact with the multi-point shrinkage ring is effectively avoided, then the punctured wound is effectively protected against infection, and potential safety hazards are reduced.

Description

technical field [0001] The invention relates to the field of renal puncture, and more specifically relates to a high-precision nephrology biopsy puncture device and a method for using the same. Background technique [0002] Needle biopsy is the main method for obtaining histopathological diagnosis of bone and soft tissue tumors. Renal puncture Renal puncture renopuncture 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] In addition, the histopathological chang...

AI Technical Summary

Problems solved by technology

[0007] Kidney puncture has high requirements on the accuracy of puncture, but due to the softness and elasticity of the skin, when the skin is subjected to the force from the puncture needle, it is prone to elastic deformation to a certain extent, causing the skin to fluctuate, resulting in a certain degree of vibration during the puncture. Offset, which affects the puncture accuracy and increases the puncture failure rate
