Detailed description of the invention
Embodiment 1
A kind of biopsy forceps as shown in Figure 1-2, comprises core bar 1, and described core bar 1 is provided with slip ring 2, be provided with boost tube 5, and described boost tube 5 is connected in described core bar 1 with slip ring 2, and described slip ring 2 can drive boost tube 5 to move together when mobile.Described core bar 1 is connected by coupling assembling 3 with binding clip assembly 4, and described coupling assembling 3 comprises spring outer tube 31, drag-line 32, butt tube 33 and flexible steel cable 34.Described spring outer tube 31 is fixedly linked with described core bar 1; Described drag-line 32 is connected with described boost tube 5; Described drag-line 32 is connected by butt tube 33 with flexible steel cable 34; It is inner that described drag-line 32, butt tube 33 and flexible steel cable 34 are installed in spring outer tube 31; Described drag-line 32 outside is coated with PE film 6, PE film 6 can reduce the frictional force of drag-line 32 when mobile.
Described binding clip assembly 4 comprises the first binding clip support 41, second binding clip support 42, first binding clip 45 and the second binding clip 46; Described first binding clip 45 and the first binding clip support 41 is integrally manufactured forms; First binding clip 45 maintains static, and being used for location, can increasing the accuracy of sampling when sampling.Described first binding clip support 41 is weldingly connected with spring outer tube 31; Described second binding clip support 42 and described flexible steel cable 34 are also for being weldingly connected; Described second binding clip support 42 and the second binding clip 42 are movably connected by second connecting rod 44; Described first binding clip support 41 and the second binding clip support 42 are movably connected by first connecting rod 43; Described first binding clip 45 and the second binding clip 46 are movably connected by connecting axle 47.When promoting slip ring 2, the power that described flexible steel cable 34 receives from drag-line 32 bends, thus promotes the second binding clip support 41, and the second binding clip 42 is opened; When losing External Force Acting, flexible steel cable 34 can restore to the original state, thus the second binding clip 46 is closed.
Described first binding clip 45 maintains static, described second binding clip 46 when rotating and the maximum open-angle α that formed of the first binding clip 45 be 90 degree.
A kind of biopsy forceps of the present embodiment, the first binding clip and the first binding clip support is integrally manufactured forms, the second binding clip can open side in the past, and maximum open-angle α is 90 degree, convenient to operation, and sampling accurately, is shortened the operating time, decreased the misery of patient.
