Secondary percussion safety block is mounted in basic blocks by positioning pin, it is described prevent being provided with sebific duct on the outside of secondary percussion safety block it is convex
Muscle, torsional spring are set around on the positioning pin, and one end offsets with basic blocks, and the other end is arranged in the positioning for preventing secondary percussion safety block
In slot and prevent that secondary percussion safety block applies outside pressure and makes to prevent secondary percussion safety block and the sebific duct convex ribs phase to described
It supports；It is provided with positive stop lug boss on the outside of the sebific duct convex ribs, after stapler is completed to fire, prevents that secondary percussion safety block enters
It is described to prevent that secondary percussion safety block is resisted against in the limiting groove of positive stop lug boss rear end when effect state.
In a preferred embodiment of the present invention, the positive stop lug boss by front end guiding step and rear end limited step
Composition, the limited step are recessed inwardly to form limiting groove.
In a preferred embodiment of the present invention, the sebific duct convex ribs with the central axis of the sebific duct part is relatively parallel sets
It sets.
In a preferred embodiment of the present invention, the central axis direction in the sebific duct part along sebific duct part is provided with horizontal recessed
Slot is provided with the convex block being slidably matched with horizontal groove in the basic blocks.
In a preferred embodiment of the present invention, the sebific duct part spliced by gluing pipe fitting and lower sebific duct part two parts and
At.
It is easy to use the beneficial effects of the present invention are: structure is simple, using sebific duct upper limit groove to percussion after the completion of
Prevent that secondary percussion safety block plays position-limiting action, the torsional spring being wound around on positioning pin will prevent that secondary percussion safety block pushes up outward, and make
Abut in the limiting groove on sebific duct, will not be subjected to displacement further along, to effectively prevent secondary percussion.
Detailed description of the invention

Specific embodiment
The technical scheme in the embodiments of the invention will be clearly and completely described below, it is clear that described implementation
Example is only a part of the embodiments of the present invention, instead of all the embodiments.Based on the embodiments of the present invention, this field is common
Technical staff's all other embodiment obtained without making creative work belongs to the model that the present invention protects
It encloses.
Please refer to Fig. 1-3, a kind of secondary percussion safety device of preventing for disposable hysteroscope Endo-GIA of the present invention, packet
Include: sebific duct part 1, the sebific duct part 1 are connected with the rear end of bearing platform 2, and basic blocks 3 are provided in the sebific duct part 1 and are prevented
Secondary percussion safety block 4, it is described to prevent that secondary percussion safety block 4 is mounted in basic blocks 3 by positioning pin 5, preventing secondary percussion
The outside of safety block 4 is provided with sebific duct convex ribs 6, and torsional spring 8 is arranged on positioning pin 5, and one end and the basic blocks 3 of torsional spring 8 offset, separately
One end is arranged in the locating slot 41 for preventing secondary percussion safety block and to preventing that secondary percussion safety block applies outside pressure, makes to prevent
Secondary percussion safety block 4 offsets with sebific duct convex ribs 6；When the first task of Endo-GIA, the center-pole of bearing platform 2 is pushed
Basic blocks 3 travel forward, and prevent that secondary percussion safety block 4 is close to sebific duct convex ribs 6 under the action of the torsion spring and is moved forwards until de-
It completes to fire from sebific duct convex ribs 6.
The outside of the sebific duct convex ribs 6 is provided with positive stop lug boss 7, the positive stop lug boss 7 by front end guiding step 71 with
