Description

Vascular irrigator for autologous arteriovenous fistula angioplasty Technical Field The utility model relates to the field of medical appliances, in particular to a vascular irrigator for autologous arteriovenous fistula shaping operation. Background Autologous arteriovenous fistula angioplasty is a medical technique for manually forming a direct pipeline between an internal arteriovenous by connecting a certain artery with a superficial vein blood vessel which is close to each other subcutaneously through surgery. The technique aims at utilizing the advantage of convenience in puncture of superficial veins, and simultaneously, directly supplying blood through arteries to increase the blood flow of the superficial veins so as to achieve the treatment requirement. This surgical method is particularly useful for patients with chronic renal failure who require prolonged hemodialysis treatment. Compared with hemodialysis catheters, the autologous arteriovenous internal fistula has the advantages of low infection incidence rate, no risk of catheter shedding and bleeding and the like. Compared with artificial endovascular fistulae, the autologous arteriovenous fistula has simple operation, low cost, long average service life, low infection rate and low thrombosis probability. There are various vascular irrigators for autologous arteriovenous internal fistula angioplasty on the market, and among them, one for autologous arteriovenous internal fistula angioplasty, with the publication number CN221845657U, has been attracting attention. The device can wash the blood vessel stably and efficiently by an automatic control technology, and ensures the cleanness and smoothness of the blood vessel cavity in the operation process. The design of the device ensures that the flushing process is more accurate and reliable, and greatly improves the success rate and the safety of the operation. The efficient working performance of the surgical operation device enables a surgeon to concentrate on the operation itself, and reduces the operation risk caused by improper flushing.
