The ureteral access sheath is a crucial conduit connecting the surgeon's work with patient safety in minimally invasive urological surgery. We will explore in detail the criticality of its structural design, its multidimensional functions in handling complex stone situations, and how LINSTANT, the manufacturer, utilizes its advanced extrusion process and post-processing technology to ensure the absolute reliability of this critical instrument. 1. ureteral access sheath: In-depth Analysis of Structure and Basic Functions The ureteral access sheath (UAS) is more than just a simple cannula; its design directly affects the degree of ureteral protection and the smoothness of the procedure. A. Refinement of Core Functions Establishing a "zero-trauma" channel: Its primary task is to establish a protective channel with a relatively constant diameter within the ureter (especially the narrower distal portion). This allows the surgeon to repeatedly insert and remove instruments such as ureteroscopes, laser fibers, and irrigation catheters without worrying about mechanical friction or tearing of the delicate ureteral wall. Maintaining a clear view and controlling pressure: During lithotripsy, the surgical field of vision is easily obscured by blood and debris. ureteral access sheaths allow for continuous and efficient infusion of saline solution and drainage of irrigation fluid and stone debris, crucial for maintaining surgical clarity. B. A Technological Leap Forward in Negative Pressure Ureteral Access Sheaths Advanced ureteral access sheath designs, such as negative pressure ureteral access sheaths, represent a significant technological advancement. This specially designed sheath integrates a negative pressure suction interface, enabling the active and rapid removal of intraoperative irrigation fluid and debris. This greatly reduces intraoperative waiting time and effectively mitigates the potential impact of intrarenal pressure fluctuations on the kidneys, truly achieving high surgical efficiency. 2.
