  • Publication number: 20240000503
    Abstract: The present application discloses a single-piece uterine cavity electric resection device, which includes a fixing rod, an operating handle, a traction wire, and a cutting electrode. The traction wire is driven to move along the guide sliding sleeve on the fixing rod by the opening and closing the operating handle, so as to control the support body connected with the traction wire, and drive the cutting electrode to unfold, fold and change the opening angle under the limitation of pulling back or pulling of the tension wire. When entering and exiting the uterine cavity, the cutting electrode can be folded under the operating of the handle, which can make the electric resection device enter and exit the uterine cavity easily, and the cutting electrode is not easy to be damaged. During treatment, the angle of cutting electrode can be adjusted flexibly and accurately in a larger range, the treatment effect is better, and the operation process is safer.

  • Patent number: 7757999
    Abstract: The present invention discloses a foldaway worktable mainly for supporting cutting tools. The foldaway worktable comprises a supporting portion and a bracket portion, wherein the supporting portion is disposed on the bracket portion and the bracket portion comprises at least two retractable bars. A connecting bar is connected to and located between the retractable bars. The bracket portion further comprises a clamping device which is rotatably mounted on the connecting bar. When the worktable is fully folded, the length of the retractable bars remains fixed by using the clamping device. The clamping device also allows for avoidance of the inconveniences that normally arise during transport of the worktable, including the unfolding and outspreading of the retractable bars. Therefore, the foldaway worktable is convenient to use whether it is being moved, stored, packed or transported.
