Abstract

The invention relates to an external ureteral catheter assembly, a ureter radiography assembly, a ureter drainage assembly and a method. The external ureteral catheter assembly comprises an external ureteral catheter, an injector interface accessory and a drainage bag interface accessory which are matched for use, wherein a first conical structure which is smooth and closed is arranged at one endof the external ureteral catheter, a drainage hole is formed in the wall of the first conical structure, an external thread structure is arranged at the other end of the external ureteral catheter, each of the injector interface accessory and the drainage bag interface accessory comprises a turn cap and a connecting cap which are integrally connected, each turn cap is provided with an internal thread structure matched with the external thread structure and used for being connected with the external ureteral catheter, the connecting cap of the injector interface accessory is used for being connected with an injector, and the connecting cap of the drainage bag interface accessory is used for being connected with a drainage bag. Diversity of functions of the same external ureteral catheter isrealized, and leakage of a contrast medium or urine is prevented.

Description

technical field [0001] The invention relates to the technical field of medical appliances, in particular to an external ureteral catheter assembly, an imaging assembly, a drainage assembly and a method. Background technique [0002] Since 1967, ureteral catheter has been used clinically. As a safe, effective and compatible diagnostic and therapeutic tool, its application has become increasingly widespread. For ureteral support, drainage, expansion. For traditional ureteral catheters, the marked length is 50 cm, but the actual length is >60 cm. It is made of polymer materials and can be displayed under X-ray fluoroscopy. It is divided into F according to its diameter. 3 , F 4 , F 5 , F 6 , F 8 And so on several commonly used models. With the development and utilization of small-diameter ureteroscopes, minimally invasive techniques such as laser lithotripsy, pneumatic ballistic lithotripsy, hydroelectric lithotripsy, and ultrasonic lithotripsy under ureteroscopy are ...
