Description

Technical Field

[0001] The utility model relates to the technical field of endoscope light sources, in particular to a ureteral endoscope cold light source. Background Art

[0002] The ureter is located in the retroperitoneal space and has a long travel distance, making it prone to blockage or compression, leading to hydronephrosis and even renal impairment. In recent years, laparoscopic ureteral surgery has gradually developed and become increasingly sophisticated. Compared with open surgery, laparoscopic surgery has obvious advantages such as less blood loss, less wound pain, early postoperative feeding, and shorter hospitalization, making it an ideal choice for treating ureteral diseases. However, laparoscopic ureteral surgery is often difficult to distinguish from other surrounding tissues during surgery because the ureter is small and has no obvious appearance features. It often takes a long time to confirm the ureteral path and the location of ureteral lesions, which can easily damage the ureter and surrounding normal tissues and organs, greatly increasing the risk of surgery and intraoperative complications.

[0003] The prior art discloses a ureteral fiber optic catheter with application number 202020515443.5, comprising a light source connector that can be connected to a cold light source, the light source connector being connected to a catheter that can be inserted into the ureter, the catheter comprising an optical fiber that can emit light from the side and a light-transmitting protective layer that is sheathed on the outside of the optical fiber. The utility model is retrogradely inserted into the patient's ureter under cystoscopy, and the light source connector is connected to the cold light source, so that the catheter is illuminated throughout the body. Under laparoscopy, the patient's ureteral path, stone location, or lesion location can be visually seen, and the ureter is distinguished from other surrounding tissues, preventing the stone from being displaced or even retreated into the kidney due to searching for the ureter and stones, or preventing tumor metastasis due to searching for the ureter and lesions. At the same time, damage to the adjacent normal tissues and organs around the ureter is also avoided to the greatest extent possible, shortening the time of laparoscopic ureteral-related surgery, reducing intraoperative complications, and improving the feasibility and safety of laparoscopic ureteral-related surgery. However, the single light source is inconvenient for precise positioning of the patient's area, thereby affecting the efficiency of treatment. Utility Model Content
