  • Patent number: 12343017
    Abstract: A disassembly-free and flushable clip applier includes: a fixing handle and a triggering handle, the fixing handle being hinged with the triggering handle, the fixing handle being provided with a locking key; an end of the cavity tube being provided with a mounting head which is configured for detachably connecting the ligating clip; a turning mechanism sleeved at the other end of the cavity tube and rotatably connected with the fixing handle through a rolling ball, the turning mechanism being provided with a flushing valve which is communicated with the cavity tube for flushing; and a thimble axially infixed into the cavity tube and reciprocating along an axial direction of the cavity tube. The clip applier does not need disassembly and reassembly during cleaning and disinfection and prevent a risk of accidental touching triggering when the ligating clip is being assembled and fails to reach a clipping position.

  • Publication number: 20240299154
    Abstract: A method of an intestinal protective ostomy with the use of a degradable intestinal diversion device and an intubation includes steps of: preparing the degradable intestinal complete diversion device; after cutting off the terminal ileum intestine, measuring the diameter of the intestine, and then selecting a degradable intestinal diversion device of appropriate specifications according to the diameter of the intestine; when diverting, placing the device in the intestinal cavity, and fixing the ileum on the device with a thread at the convex ring; inserting the stoma drainage tube in the proximal ileum where the device is placed against the direction of intestinal peristalsis; and disintegrating and discharging the device with the contents of the intestine. The invention used with a drainage tube realizes complete intestinal diversion without secondary operations of stoma reintroduction.

  • Publication number: 20240156465
    Abstract: The invention provides a ligating clip for continuous firing and a process, which can arrange a plurality of ligating clips diastolically and orderly in the same direction and fix them in a continuous firing cartridge; Moreover, the ligating clip in the cartridge can be compressed to the allowable range of the puncture cannula by directionally moving the continuous firing cartridge in the cartridge sleeve, and the continuous firing cartridge can be separated from the cartridge sleeve; Alternatively, after the positioning guide post is arranged on the side cartridge, the positioning guide post is provided with a positioning groove, so the ligating clip is precisely positioned into the T-shaped upper slot between the first upper cartridge and the second upper cartridge, and the T-shaped lower slot between the first lower cartridge and the second lower cartridge, convenient to install the ligating clip while the ligating clip can be effectively positioned.
