Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a visual bladder puncture device. Background Art

[0002] Cystocentesis is an invasive urological procedure suitable for patients with urinary retention due to various reasons who cannot undergo indwelling catheterization or whose indwelling catheterization has failed. In such cases, cystocentesis is necessary to relieve the symptoms of urinary retention. Generally, the bladder is filled before puncture. A full bladder ensures safe puncture and avoids puncturing the dorsal bladder or causing rectal injury. During puncture, the bladder must be entered, which can be observed by urine flow. Cystocentesis involves dilating the bladder from thin to thick, and severe bleeding must be avoided.

[0003] A Chinese utility model patent with authorization publication number "CN202078372U" discloses a "cystostomy puncture device," which includes a urinary catheter groove within the puncture needle, a urine inlet opening on the sidewall of the needle tip, and a urine outlet opening near the operating handle. The outer cannula is equipped with a shutoff valve on the side of the branch tube near the puncture needle tip. However, during cystostomy puncture using this puncture device, the needle can easily damage surrounding tissue, rupture blood vessels, and induce bleeding because the puncture progress cannot be observed in real time.
