In medical science applied surgical operation, since 20th century invention sixties first staple series products, Medical stapler has become the requisite a kind of medical apparatus and instruments aiding in edge of a knife sewing process.Along with development and the research and development of products of medical science, more and more multi-functional staple series products is applied to clinical.The scope of application has related to the every field such as gastrointestinal surgery, Genneral Surgery, thoracic surgery, Urology Surgery, department of obstetrics and gynecology, becomes one of requisite instrument of doctor.Thereby for patient have less hemorrhage, less operating time in art, with apparatus replace reducing due to error that craft causes by hand, avoid infection, postoperative function recovers the multiple advantage such as fast.
A kind of interior safety of typical anastomat, comprise interior insurance, straight push rod, draw back plate, flexible handle, on fixed handle, be provided with insurance bearing pin, interior insurance is rotatably installed on insurance bearing pin, the sliding end of interior insurance contacts with the guard terminal of flexible handle, when using anastomat, rotate rotary handle, the straight push rod of anastomat drives draw back plate to move right, in the interior insurance drag hook of draw back plate drives, insurance is rotated, thereby interior insurance sliding end is removed the guard terminal of flexible handle, thereby flexible handle can freely-movable, carries out next step operation.But sometimes, in the process of rotary handle of rotating anastomat, there will be the more difficult rotation of rotary handle, firmly rotation causes interior insurance to damage, thereby makes interior termination of insurance status, and the safety effect of interior insurance is bad.
Therefore, how improving the safety effect of the interior insurance of anastomat, is the current technical issues that need to address of those skilled in the art.
Summary of the invention
The interior safety that the object of this invention is to provide a kind of anastomat, the safety effect of these interior safety is better.Another object of the present invention is to provide a kind of anastomat that comprises above-mentioned interior safety.
To achieve these goals, the invention provides a kind of interior safety of anastomat, comprise flexible handle, draw back plate and interior insurance, the sliding end of described interior insurance and the guard terminal of described flexible handle are circular-arc, described sliding end and described guard terminal match, and described interior insurance coordinates with draw back plate.
Preferably, on the draw back plate of described anastomat, be provided with connecting hole, the link of described interior insurance is arranged in described connecting hole.
Preferably, the draw back plate of described anastomat is provided with interior insurance drag hook, is provided with link and described interior insurance drag hook butt that spring makes described interior insurance in described interior insurance.
Preferably, on the draw back plate of described anastomat, be provided with pointer drag hook.
Preferably, be provided with and can slide and fixing regulating block with respect to described straight push rod on the straight push rod of described anastomat, described regulating block is connected with the draw back plate of described anastomat.
Preferably, described regulating block is the U-shaped regulating block of elasticity, and the U-shaped regulating block of described elasticity is clipped on described straight push rod.
The present invention also provides a kind of anastomat, comprises device body and the interior safety that are connected with described device body, it is characterized in that, described interior safety are the interior safety described in above-mentioned any one.
The interior safety of anastomat provided by the invention, comprise flexible handle and interior insurance, and the sliding end of interior insurance and the guard terminal of flexible handle are circular-arc, and sliding end and guard terminal match.When using anastomat, rotate the rotary handle of anastomat, straight push rod drives draw back plate to move right, insurance motion in draw back plate drives, because the guard terminal of the sliding end of interior insurance and flexible handle is circular-arc, the guard terminal motion smoothing of the relative flexible handle of sliding end of interior insurance, rotary handle, and interior insurance is more like a cork stressed smoothly not fragile.
Known by foregoing description, with respect to background technology, the interior safety of anastomat provided by the invention, the sliding end of interior insurance and the guard terminal of flexible handle are circular-arc, rotary handle, and interior insurance is more like a cork stressed smoothly not fragile, and the safety effect of interior insurance is better.
Accompanying drawing explanation
The structural representation of the anastomat that Fig. 1 provides for the embodiment of the present invention;
Fig. 2 is the partial enlarged drawing at the A place shown in Fig. 1;
Fig. 3 is the explosive view of the insurance adjusting device of the anastomat shown in Fig. 1.
The specific embodiment
Core of the present invention is to provide a kind of interior safety of anastomat, and the safety effect of these interior safety is better.Another core of the present invention is to provide a kind of anastomat that comprises above-mentioned interior safety.
In order to make those skilled in the art understand better technical scheme of the present invention, 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 specific embodiment, the interior safety of the anastomat that the embodiment of the present invention provides, comprise flexible handle 1 and interior insurance 5, the sliding end 51 of interior insurance 5 is circular-arc with the guard terminal 11 of flexible handle 1, and sliding end 51 matches with guard terminal 11.When using anastomat, rotate the rotary handle 2 of anastomat, straight push rod 3 drives draw back plate 6 to move right, insurance 5 motions in draw back plate 6 drives, because the sliding end of interior insurance 5 51 is circular-arc with the guard terminal 11 of flexible handle 1, guard terminal 11 motion smoothings of the sliding end 51 relative flexible handles 1 of interior insurance 5, rotary handle 2 more like a cork, and interior insurance 5 is stressed smoothly not fragile.The interior safety of the anastomat that the embodiment of the present invention provides, the sliding end 51 of interior insurance and the guard terminal of flexible handle 1 11 are circular-arc, and rotary handle 2 more like a cork, and interior insurance 5 is stressed smoothly not fragile, and the safety effect of interior insurance 5 is better.The draw back plate 6 of above-mentioned anastomat is provided with interior insurance drag hook 61, is provided with link and interior insurance drag hook 61 butts that spring makes interior insurance 5 in interior insurance 5.
