Abstract: The present disclosure provides an interventional needle fixing device for tumor clinical treatment, including an interventional needle adjustment mechanism. The interventional needle adjustment mechanism includes a roll adjustment assembly, a pitch adjustment assembly, a rotating assembly and a needle tube assembly. In the present disclosure, by arranging the interventional needle adjustment mechanism, when facing tumor lesions in different positions, doctors make the needle tube assembly realize left or right roll adjustment in a horizontal direction through the roll adjustment assembly, thereby accurately aligning a target area. At the same time, the pitch adjustment assembly can control the needle tube assembly to pitch upward or downward in a vertical direction, thereby meeting the diversified requirements of interventional needle angles in various complex surgical scenes, and improving the flexibility and accuracy of interventional needle puncture.

Abstract: The present disclosure belongs to the technical field of medical devices, and in particular relates to a post-operative indwelling urinary catheter suitable for males. In view of a problem that a urinary catheter is prone to shaking due to collision, in the present disclosure, by arranging a shield, a limiting ring is rotated to adjust a connection position of a spiral tube and a chassis, and the shield is pushed to cause a fixing soft disk to be abutted against a human body, avoiding the possibility of urethral irritation or injury when an external urinary catheter I is shaken, avoiding bacterial invasion and urinary tract infection, and improving the comfort of use.
