Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a nephrology-assisted renal puncture device. Background Art

[0002] Renal puncture is a renal biopsy, also known as renal puncture biopsy. Due to the wide variety of kidney diseases, complex etiologies and pathogenesis, the clinical manifestations of many kidney diseases are not completely consistent with the histological changes of the kidneys. For example, the clinical manifestations of nephrotic syndrome can be pathologically manifested as microlesions, mild lesions, mild mesangial proliferation, membranous nephropathy, membranoproliferative nephritis, focal segmental sclerosis and other changes, and the treatment plans and the development of the disease are also very different.

[0003] Depending on the needs of the patient, the doctor may need to perform consecutive operations. The operation requires the doctor to be serious and keep his hands steady. Therefore, it is a big test for the arms and physical strength. Especially when the operation is lasting for a long time, keeping the arms suspended in the air for a long time can cause numbness and shaking, which will affect the accuracy of the operation, prolong the operation time, and increase the risk of the operation.

[0004] Now there is a need to invent a nephrology-assisted renal puncture device to support the doctor's arms during the operation and adjust the arm angle during the operation. Summary of the invention
