Remaining needle fixing device

A remaining needle fixing device effectively solves the problem that the remaining needle fixing effect is poor. Comprising a shell with an upward opening in the left-right direction, binding belts are arranged at the left end and the right end of the shell respectively, an inverted-L-shaped supporting plate is arranged in the shell, a fixing plate in the front-back direction is slidably connected to the supporting plate, and the lower end of the fixing plate penetrates through the supporting plate and is provided with a pull rope; the free end of the pull rope is fixedly connected with the rotating wheel. The upper end of the rotating wheel is provided with a left-right shielding plate capable of blocking the opening of the shell. The remaining needle fixing device is ingenious in design and convenient to use, a remaining needle can be fixed by turning over the shielding plate, meanwhile, a remaining needle connector can be sealed, medical staff can fix the remaining needle conveniently, and meanwhile the re
