Description

Observer for ureter narrow section in operation

Technical Field

The utility model belongs to the technical field of the medical instrument technique and specifically relates to an observer for ureter stenosis section in operation.

Background

With the popularization of minimally invasive technologies such as ultrasonic lithotripsy and ureteroscope lithotripsy, the incidence of ureteral stenosis gradually increases. With the popularization of the laparoscope technology, the ureteral stenosis laparoscope repair technology is rapidly developed. Laparoscopic ureteral repair procedures are safe and minimally invasive, but these procedures still present technical challenges. Accurate positioning of ureteral stenosis is critical for ureteral repair. The surgeon must excise the entire diseased site to minimize the risk of recurrence of ureteral stenosis, while at the same time retaining as much of the healthy ureter as possible for a tension-free anastomosis. However, in the case of inflammation around the ureter, accurate identification of the ureteral stenosis presents an obstacle, since inflammation around the ureter is usually accompanied by pathological changes, disrupting the normal anatomical level and leading to fibrosis wrapping the ureter. Without tactile feedback, surgeons rely to a large extent on visual judgment, and therefore accurate positioning of ureteral stenosis presents difficulties. Indocyanine green (ICG) is a dye that can be visualized under near infrared fluorescence (NIRF) and can be used to visualize ureteral strictures in intraoperative applications. However, the technology needs special equipment, and the contact of patients can cause adverse reactions such as shock, allergy, nausea, fever and the like, and although the occurrence probability is low, the popularization and the application of the technology in clinic are limited to a certain extent. The ureteral illuminator in the prior art can only assist in identifying the ureter, but cannot assist in identifying the ureter stenosis and its edges.
