The scope of application has related to the every field such as gastrointestinal surgery, liver and gall surgical department, thoracic surgery, Urology Surgery, Obstetric and Gynecologic Department, becomes one of essential instrument of doctor. For patient have less operating time hemorrhage, less in art, with apparatus replace manual thus reduce cause due to craft error, avoid infection, postoperative function recover the multiple advantage such as fast.
The interior safety interlock of a kind of typical stapler, comprise interior insurance, straight push rod, push-and-pull plate, free handle, fixing handle is provided with safety pin shaft, interior insurance is rotatably installed in safety pin shaft, the sliding end of interior insurance contacts with the insurance end of free handle, when using stapler, rotate and rotate handle, the straight push rod of stapler drives push-and-pull plate to move right, in the interior insurance drag hook of push-and-pull plate drives, insurance is rotated, thus interior insurance sliding end removes the insurance end of free handle, thus free handle can free movement, carry out next step operation. But sometimes in the process of rotation handle rotating stapler, there will be and rotate the more difficult rotation of handle, firmly rotate and then cause interior insurance to damage, thus make interior avoidance of policy, the safety effect of interior insurance is not good.
Therefore, how to improve the safety effect of the interior insurance of stapler, it is the current technical issues that need to address of those skilled in the art.
Summary of the invention
It is an object of the invention to provide the interior safety interlock of a kind of stapler, the safety effect of these interior safety interlock is better. It is a further object of the present invention to provide a kind of stapler comprising above-mentioned interior safety interlock.
In order to realize above-mentioned purpose, the present invention provides the interior safety interlock of a kind of stapler, comprise free handle, push-and-pull plate and interior insurance, the sliding end of described interior insurance and the insurance end of described free handle are circular arc shape, described sliding end and described insurance end match, and described interior insurance coordinates with push-and-pull plate.
Preferably, the push-and-pull plate of described stapler being provided with and connects hole, the coupling end of described interior insurance is arranged in described connection hole.
Preferably, the push-and-pull plate of described stapler is provided with interior insurance drag hook, described interior insurance is provided with spring and makes the coupling end of described interior insurance and described interior insurance drag hook to connecing.
Preferably, the push-and-pull plate of described stapler is provided with pointer drag hook.
Preferably, the straight push rod of described stapler being provided with and can slide relative to described straight push rod and fixing adjustment block, described adjustment block is connected with the push-and-pull plate of described stapler.
Preferably, described adjustment block is that elastic u-shaped regulates block, and described elastic u-shaped regulates block to be clipped on described straight push rod.
Present invention also offers a kind of stapler, the interior safety interlock comprising device body and being connected with described device body, it is characterised in that, described interior safety interlock are the interior safety interlock described in above-mentioned arbitrary item.
The interior safety interlock of stapler provided by the invention, comprise free handle and interior insurance, and the sliding end of interior insurance and the insurance end of free handle are circular arc shape, and sliding end matches with insurance end. When using stapler, rotate the rotation handle of stapler, straight push rod drives push-and-pull plate to move right, insurance motion in push-and-pull strip is dynamic, because the insurance end of the sliding end of interior insurance and free handle is circular arc shape, the insurance end motion smoothing of the sliding end relative motion handle of interior insurance, it is possible to more easily rotate handle, and interior insurance smoothly not easily damages by power.
By foregoing description it will be seen that relative to background technology, the interior safety interlock of stapler provided by the invention, the sliding end of interior insurance and the insurance end of free handle are circular arc shape, can more easily rotating handle, and interior insurance smoothly not easily damages by power, the safety effect of interior insurance is better.
Accompanying drawing explanation
The structural representation of the stapler that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the partial enlargement figure at the A place shown in Fig. 1;
Fig. 3 is the explosive view of the insurance setting device of the stapler shown in Fig. 1.
Embodiment
The core of the present invention is to provide the interior safety interlock of a kind of stapler, and the safety effect of these interior safety interlock is better. Another core of the present invention is to provide a kind of stapler comprising above-mentioned interior safety interlock.
In order to make those skilled in the art understand the technical scheme of the present invention better, below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
Please refer to Fig. 1-Fig. 3, in a kind of embodiment, the interior safety interlock of the stapler that the embodiment of the present invention provides, comprise free handle 1 and interior insurance 5, the sliding end 51 of interior insurance 5 is circular arc shape with the insurance end 11 of free handle 1, and sliding end 51 matches with insurance end 11. When using stapler, rotate the rotation handle 2 of stapler, straight push rod 3 drives push-and-pull plate 6 to move right, push-and-pull plate 6 drives interior insurance 5 to move, because the sliding end of interior insurance 5 51 is circular arc shape with the insurance end 11 of free handle 1, insurance end 11 motion smoothing of the sliding end 51 relative motion handle 1 of interior insurance 5, it is possible to more easily rotate handle 2, and interior insurance 5 smoothly not easily damages by power. The interior safety interlock of the stapler that the embodiment of the present invention provides, the sliding end 51 of interior insurance and the insurance end 11 of free handle 1 are circular arc shape, it is possible to more easily rotate handle 2, and interior insurance 5 smoothly not easily damages by power, and the safety effect of interior insurance 5 is better. The push-and-pull plate 6 of above-mentioned stapler is provided with interior insurance drag hook 61, interior insurance 5 is provided with spring and makes the coupling end of interior insurance 5 and interior insurance drag hook 61 to connecing.
In addition, the push-and-pull plate 6 of stapler being provided with and connects hole, the coupling end of interior insurance 5 is arranged at and connects in hole. Arrange like this and interior insurance 5 can be more conveniently installed, and connect the stable connection of hole and interior insurance 5.
In addition, the push-and-pull plate 6 of stapler being provided with pointer drag hook, the pointer drag hook on push-and-pull plate 6 can pull indicators turn, makes push-and-pull plate 6 not only can pull interior insurance 5 but also can pull pointer.
Further, the straight push rod 3 of stapler being provided with the adjustment block 4 that can slide relative to straight push rod 3 and fix, described adjustment block 4 is connected with the push-and-pull plate 6 of described stapler.
