Abstract

The invention relates to a pair of anti-skid micro scissors. The pair of anti-skid micro scissors comprises a scissors body, the scissors body comprises two scissors arms hinged to each other, two scissors arms are arranged in a crossing manner, a scissors head is arranged at one end of every scissors arm, a handle is arranged at the other end of every scissors arm, a cutting edge is arranged at the inner side of every scissors head, and every cutting edge comprises a plurality of saw teeth. The anti-skid micro scissors can prevent a blood vessel from skidding in the blood vessel shearing process.

Description

technical field [0001] The invention relates to the field of micro scissors, in particular to anti-slip micro scissors. Background technique [0002] Arteriovenous fistula is a vascular access for patients with chronic renal failure to maintain hemodialysis, and the quality of the arteriovenous fistula has an important impact on the effect of dialysis and the long-term survival of patients. Since Brescia et al first successfully established an arteriovenous fistula by subcutaneous anastomosis of the radial artery and the cephalic vein in 1966, for various chronic glomerulonephritis, diabetic nephropathy, hypertensive renal arteriosclerosis, renal failure, polycystic kidney disease, erythema Arteriovenous fistulaplasty has become the treatment of choice for patients with renal impairment caused by various diseases such as lupus nephropathy requiring hemodialysis. At present, there are many surgical methods for arteriovenous fistula formation at home and abroad, among which b...
