Clinical application of Vathin disposable electronic ureteroscope in urology

Ureteroscopy is an important tool for the diagnosis and treatment of urinary calculi, with its development traceable back to the end of the 19th century when it was invented by the German doctor Dr. Werner Jacob. The original ureteroscope was made of metal material, with a long rod-shaped body and a viewing window and operating port at the end. Due to the limitations of medical technology at that time, the operation difficulty of this type of ureteroscope and the damage to the ureter were both relatively high.

In the 1960s, with the advancement of optical technology, the flexible ureteroscopes became thinner and were able to enter the ureter. Fiberoptic technology was adopted, which enhanced the clarity and stability of image transmission, enabling doctors to more accurately determine the location and size of the stones.

Electronic ureteroscope

With the advancement of technology in recent years, electronic ureteroscopes are gradually replacing the traditional rigid ureteroscopes. The electronic ureteroscope uses advanced electronic imaging technology to provide clearer and more realistic images, allowing doctors to more accurately observe the internal lesions of the ureter. At the same time, the flexibility and operability of electronic ureteroscopy have also been greatly improved, which can better adapt to the anatomical structure and pathological characteristics of patients. Ureteroscopy has become one of the important tools for the diagnosis and treatment of urinary calculi in urology. Its clinical application is constantly expanding, not only for the diagnosis and treatment of urinary calculi, but also for the treatment of other urinary diseases, such as urinary tract tumors. Now, more and more doctors and patients are beginning to accept and use flexible ureteroscopes, which are gradually becoming one of the routine diagnostic and therapeutic methods in urology.

The clinical application requirements of flexible ureteroscopy

Application of flexible ureteroscopy in stone disease Stone disease is a disease caused

by abnormal mineralization in the human body, resulting in the accumulation and formation of calcium salts or lipids. Such as gout caused by uric acid deposition, calcium salt deposition caused by metabolism, and various types of stones related to infection, foreign body deposition, and other factors。

The symptoms of urinary calculi usually include specific manifestations in several locations, such as ureteral calculi, renal calculi, renal pelvis calculi, renal calyces calculi, and bladder calculi. /span>

The treatment methods vary according to the location and size of the patient's stone. Ureteroscopy is mainly used for the treatment of upper ureteral stones and kidney stones smaller than 2cm:

1. It is mainly used to treat small stones. In general, stones less than 2cm can be treated using flexible ureteroscopy technology.

2. For some large stones, such as 5-6 cm stones, patients with isolated kidneys or poor physical conditions, or patients who are resistant to percutaneous nephrolithotomy, can be treated with flexible ureteroscopy.

3. In clinical applications, combine holmium laser to crush stones and then let patients excrete them. For larger fragments of stones, a stone basket can also be used to extract the stone through the ureteroscope.

The flexible ureteroscope technology enters the body through the natural urethral cavity of the human body, using the natural urinary tract of the body without making any incisions on the body, which has the advantages of minimal invasion, safety, less patient pain, and rapid recovery. Meanwhile, it has the advantages of clear vision, flexible and bendable scope, clean stone removal, and short treatment period.

II. Application of flexible ureteroscopy in the diagnosis

and treatment of ureteral tumors Diagnosis of ureteral tumors is one of the more difficult diagnoses of urologic tumors Traditional pathological examination methods are difficult to obtain sufficient tissue samples, and the application of ureteroscopy technology provides a new method for the diagnosis of ureteral tumors. The doctors can directly observe the pathological changes inside the ureter and obtain sufficient tissue samples for pathological examination through the ureteroscope. For the treatment of ureteral tumors, under the guidance of ureteroscopy,

doctors can use various methods such as laser, electrocautery, and drug injection to locally treat the tumor, thus alleviating the pain of patients and reducing surgical trauma.

The clinical application advantages of Vathin Medical disposable ureteroscope

Ureteroscopy is one of the most commonly surgical procedures in urology, but unfortunately, reusable ureteroscopes are expensive and require frequent and expensive maintenance.

The single-use flexible ureteroscopeis designed with disposable sterile packaging, ensuring one-to-one use and preventing cross-infection. No need for decontamination maintenance, plug and play, lightweight and portable, easy to operate, better cost-effectiveness. As a powerful tool in urology, it enables doctors to provide more efficient and quality medical services for patients with stones.

Vathin Medical's disposable flexible ureteroscope has the performance of reusable endoscopes, but can achieve the price of disposable consumables,which stems from multiplebreakthroughs in core technologies.

Patent riveted snake bone design， comparable to the overall maneuverability of reusable endoscopes; The head can bend up and down at an ultra-wide angle of 285°, reaching all the renal lumens;It can guide the flexible head negative pressure sheath to reach the lower calyx of the kidney, making it the best partner; Patent self-locking + stepless self-locking function, unlocking means no lock, control is more free, locking is stepless, positioning is more accurate; The insertion tube can be rotated horizontally by 90° left and right without changing the grip posture, and adjusted to the optimal field of view.

With the enhancement of independent research and development capability of key technologies and front-end components, Vathin Medical's products are continuously updated.Vathin II generation ureteroscope has been newly upgraded and launched，bringing better diagnosis and treatment experience and better assistance to doctors.
