A kidney sampling puncture needle that can effectively relieve pain and reduce trauma

Abstract

The invention discloses a kidney sampling puncture needle capable of effectively alleviating pain and reducing wounds, and relates to a puncture needle. An outer needle bolt (10) is arranged at one end of a thick needle stick (8). A half of the other end of the thick needle stick is connected with a semicircular needle stick (4). The end part of the semicircular needle stick is connected with a half of the large end of a needle point (1). A through hole B (17) is formed from the other half of the other end of the thick needle stick to a jack A (18) of the outer needle bolt. An inner needle tube (5) is inserted into the through hole B of the thick needle stick. The inner surface of the end part of one end of an inner needle tube through hole A (6) forms an inner inclined surface (3). The outer wall of an inner needle bolt (13) at the other end of the inner needle tube is spliced with the jack A of the outer needle bolt. The inner needle tube is eccentrically connected with the inner needle bolt. A cap (15) is buckled with the inner needle bolt. According to the kidney sampling puncture needle, the needle point on the thick needle stick is used for puncturing, the inner needle tube covered by the needle point can be used for obtaining cleaner living kidney tissues, and in a puncturing process, the pain is effectively alleviated, and skin tissues mixed in the living kidney tissues can be reduced.

Description

【Technical field】 [0001] The invention relates to a puncture needle, in particular to a kidney sampling puncture needle which can effectively relieve pain and reduce trauma. 【Background technique】 [0002] As we all know, the kidney is an important organ of the human body with a complex structure and multiple functions. The pathological diagnosis of renal puncture biopsy is an important component of nephrology today, an important branch of pathology, and a must for the diagnosis of kidney diseases. Indispensable means; Renal puncture renopuncture is kidney biopsy, also known as renal puncture biopsy; Renal puncture biopsy can help clinicians formulate diagnosis and treatment plans; It can determine the presence or absence, pathological type and severity of renal transplant rejection, and Make a clear pathological diagnosis of acute tubular necrosis, cyclosporine poisoning, and recurrent and recurrent glomerulonephritis in transplanted kidneys; currently, ultrasound-guided pu...

[0002] It is well known that the kidney is an important organ of the human body with a complex structure and multiple functions. Renal biopsy and pathological diagnosis are an important component of nephrology today , is an important branch of pathology and an essential means for the diagnosis of kidney diseases; renal biopsy is renal biopsy, also known as renal biopsy; the development of renal biopsy can help clinicians formulate diagnosis and treatment plans; can determine The existence, pathological type and severity of renal transplant rejection, and make a clear pathological diagnosis of acute tubular necrosis, cyclosporine poisoning, recurrent and recurrent glomerulonephritis in the transplanted kidney; currently, ultrasound is mostly used clinically Guide the puncture operation, because the existing puncture needle structure is mostly a syringe needle structure, that is, a bevel is made at the front end of the tubular needle to form the needle tip; when the needle tip at the front end of the tubular needle is punctured, the blade surface of the nozzle at the rear of the needle tip will be synchronized Cut off the skin and flesh tissue and hide it in the needle tube, which not only brings great pain to the patient, but also mixes the skin and flesh tissue in the living kidney tissue, which affects the accuracy of pathological diagnosis in the later stage
