Description

Technical Field

[0001] The present invention relates to the technical field of nephrology, and in particular to a puncture device for nephrologists with high operating stability. Background Art

[0002] As we all know, kidney disease is a common and frequently occurring disease. If it worsens, it can develop into uremia, which seriously endangers people's health. Chronic kidney disease has become another important disease that threatens human health after cardiovascular and cerebrovascular diseases, tumors, and diabetes, and has become a global public health issue. Kidney disease refers to damage to kidney structure and function caused by various reasons, which leads to kidney pathological damage, abnormal blood or urine components, and other symptoms. Common symptoms of patients include edema, oliguria or anuria, hematuria, proteinuria, hypertension, anemia, low back pain, etc. There are many causes of kidney disease, including genetic factors, infection, drug poisoning, immune diseases, metabolic diseases, etc. The mortality rate of kidney disease varies depending on factors such as the cause, severity of the disease and treatment measures. Prevention and early diagnosis are very important for reducing the mortality rate of kidney disease. There are many types of kidney disease, which can generally be divided into glomerular disease, tubular disease, interstitial renal disease and vascular disease according to the site of lesion involvement. They can be subdivided into acute kidney injury and chronic renal failure according to the degree, reversibility and time of occurrence of kidney function damage. Kidney disease itself is not an infectious disease and therefore cannot be transmitted to others through contact, airborne transmission and other means.

[0003] At present, puncture operation is usually required in the treatment of kidney disease. The specific process is: use lidocaine for local anesthesia at the puncture point, take a ten-centimeter-long intracardiac puncture needle, and vertically insert it from the puncture point to the renal capsule, and then vertically insert the puncture needle into the renal capsule to observe the movement of the lower pole of the kidney with breathing; during this process, the puncture needle needs to maintain a stable vertical state, but the existing technology lacks a device to assist the puncture needle in maintaining high stability, so that the puncture needle is prone to shaking during the puncture process, thereby affecting the puncture effect; for this reason, a puncture device for nephrologists with high operation stability is proposed.
