Sheath follows the meaning of the mirror, with universal bending
Bending angle: 0-200 °;
By negative pressure suction, blood, pus coating, and crushed stone powder in the renal pelvis and calyx system can be effectively and quickly aspirated, maintaining a clear field of view under the microscope and improving surgical efficiency
Solve the problem of laser lithotripsy powder sinking to the bottom of the renal pelvis and the inability to retrieve stones from the stone basket.
There are unique advantages for ureteral stones, especially upper ureteral stones.
Processing range: 6F-18F

The disposable vascular guidance catheter consists of an ultra-soft tip, a multi-segment hardness catheter body, a catheter holder, a stress relief tube, and a visualization ring for introducing interventional instruments or diagnostic instruments into the peripheral, coronary, and neurovascular systems.
The core competitiveness is hidden in the four layers of precision structure at its head end:
Inner layer: PTFE, PI, TPU, PA, PEBAX, PEEK, etc
Visualization ring: better visibility, more accurate positioning, safer operation
Interlayer: stainless steel 304, NITI, Tungsten, etc.
Knitting mode :1*1, 1* 2,2 *2
Inner spring braid interlayer: stainless steel 304, NITI, Tungsten, etc.
Knitting mode: single strand/multi-strand coil spring, fixed density/variable density
Outer layer: Nylon, TPU, PEBAX, PEEK, etc

It has good bending resistance and compliance.
Design of developing ring at the front end of conveying sheath tube, accurate positioning during operation;
Anti-backflow valve design to prevent blood backflow and intake;
Structure:
The outer PEBAX material provides excellent biocompatibility and reduces intraoperative tissue damage.
The middle layer of stainless steel spiral structure provides support, folding resistance, flexibility;
The inner PTFE material reduces the push resistance, and the plugging device is transported more smoothly;
Processing range: 9F-26F

A ureteral access sheath (UAS) used during ureteroscopy to protect the ureter and facilitate multiple instrument exchanges. It allows for repeated passage of the ureteroscope and other instruments, while also improving irrigation flow and visualization within the ureter. Essentially, it acts as a conduit, protecting the ureter from damage during procedures like kidney stone removal.

Used to establish a channel outside the human body into the human body, stainless steel wire mesh is used in the catheter to strengthen the support performance, bending resistance, push performance and achieve 1:1 torque effect.
Scope of application:
Uses: Microcatheter, guiding catheter, electrophysiological catheter, delivery sheath tube (stent delivery system, occluder delivery system, etc.)
Structure: braided sheath, spring sheath, controllable sheath, etc

The product is used for general endovascular procedures, including infusion of diagnostic preparations (such as contrast agents) and therapeutic devices (such as coil springs) into peripheral, coronary, and neurovascular vessels.
Main features of the product:
* Unique large chamber provides ease of instrument delivery and recovery
