The nail bin seat of the nail bin seat of disposable intracavity Endo-GIA takes following technical scheme to realize:
The nail bin seat of disposable intracavity Endo-GIA has circular arc nail bin pedestal, inside circular arc nail bin pedestal, be provided with nail bin mounting groove; Circular arc nail bin pedestal arc surface is provided with cutting blade sliding tray, cutting tool rest sliding tray is provided with outside cutting blade sliding tray, circular arc nail bin pedestal both sides are provided with nail bin fixed groove, circular arc nail bin pedestal rear end is provided with nail supporting base dowel hole, is provided with nail supporting base in both sides, circular arc nail bin pedestal rear end and locating platform is installed.Nail bin seat locking step is provided with in cutting tool rest sliding tray rear end.
Described circular arc nail bin pedestal adopts powder metallurgy pressing molding or machining.
Cutter have blade, are provided with upper cutter head on the top of blade, are provided with lower tool rest in the bottom of blade.
When nail bin seat and the cutting of disposable intracavity of disposable intracavity Endo-GIA are kissed, stiching instrument supports the use, nail bin is fixed in nail bin seat by nail bin fixed groove, the blade of cutter is arranged in cutting blade sliding tray, the upper cutter head of cutter is arranged in cutting tool rest sliding tray, the cutter upper cutter head exterior arc surface of cutter is mutually contour with circular arc nail bin pedestal exterior arc surface, guarantees that the upper cutter head of cutter is not higher than circular arc nail bin seat plane.
Nail supporting base locates lockhole by nail supporting base, alignment pin is arranged on nail bin base rear end, installs locating platform, make nail supporting base two sides and nail bin seat two sides smooth because two sides, nail bin seat rear portion are provided with nail supporting base.
The nail bin groupware that nail supporting base, nail bin, anastomosis staple, pushing slice of nail, pushing block and nail bin seat are formed, thimble assembly 2 front end is arranged on by upper and lower adaptor, be assembled into changeable osculating device, sleeve pipe group body rear end is contained in the fixed sleeving front aperture of disposable intracavity Endo-GIA again, can uses.
The nail bin seat meter of disposable intracavity Endo-GIA is established rationally, compact conformation, because nail bin seat adopts circular arc nail bin pedestal, arc surface at the bottom of circular arc nail bin pedestal is provided with cutting blade sliding tray, cutting tool rest sliding tray is provided with outside cutting blade sliding tray, cutter upper cutter head is arranged in cutting tool rest sliding tray, the upper cutter head exterior arc surface of cutter is mutually contour with circular arc nail bin pedestal exterior arc surface, guarantee cutter upper cutter head not higher than circular arc nail bin seat plane, owing to being provided with nail supporting base in two sides, nail bin seat rear portion, locating platform is installed, make nail supporting base two sides and nail bin seat two sides smooth, therefore cut tool rest when osculating is organized and pulled out in use procedure perforator sealing ring to be pulled open, can guarantee that osculating operation is carried out smoothly.
