The using method of this straight line anastomat is: will follow closely cartridge component 2 and be contained in nail casket guide card 10 front ends, can carry out sew application: make the tissue that to sew up earlier between forward nail supporting base 1 of anastomat and nail cartridge component 2, pull trigger 11 and promote the interior positioning needle 5 of nail casket by positioning needle saddle 7, tissue is enclosed between nail supporting base 1 and the nail cartridge component 2, advance nail casket guide card 10 that the nail casket is compressed tissue to nail supporting base simultaneously, after finishing this sealing and compressing operation, trigger resets, and then pull trigger 11 drive nail pushing device guide cards 6 and pull the trigger the interior nail pushing device 3 of nail casket forward, the travel forward titanium nail in percussion the place ahead of nail pushing device 3 passes tissue and acts on nail supporting base 1, as the stapler of common usefulness tissue is stitched together.
The requirement of surgical linear anastomat is followed closely casket and can only disposablely be used, and the nail casket of therefore finishing the percussion operation promptly can not repeat to be pulled the trigger, and has only again and correctly just can carry out sew application behind the new nail of the installation casket.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of disposable percussion safety of surgical linear anastomat that make the nail casket of finishing after percussion is operated can not be repeated and pull the trigger, only just can operate after new nail casket is by correct installation.
The technical scheme that addresses the above problem is (referring to implementing illustration): this utility model is provided with the elbow (8) that opening makes progress at frame arm (9) front end, the rear wall that the elbow front end upwards bends body is provided with linear nail supporting base (1), the nail casket guide card (10) that is in transmission connection with rear portion trigger (11) is housed on the frame arm, nail casket guide card front end is equipped with nail cartridge component (2), frame arm (9) is provided with the positioning needle saddle (7) that can push ahead positioning needle (5) in the nail casket, with the nail pushing device guide card (6) that can pull the trigger nail pushing device (3) in the nail casket forward, positioning needle saddle (7) is in transmission connection with nail pushing device guide card (6) and described trigger (11), it is characterized in that: described nail cartridge component (2) bottom surface is attached on elbow (8) bottom surface, be provided with the elastomer (12) of above-below direction in lining, elbow bottom surface recessed cavity (8a), the elastomer top is provided with and protrudes upward cavity, exceed the elbow bottom surface, retaining is at the safety plate (13) in nail pushing device guide card (6) the place ahead, the part rear portion that safety plate exceeds the elbow bottom surface is vertical or is bordering on vertical sheer face, and the front portion is sweptback inclined-plane or cambered surface.
Operation principle of the present utility model is: generally, elastomer (12) pop up be in upper, safety plate (13) protrudes upward cavity, exceed the elbow bottom surface, retaining is in nail pushing device guide card (6) the place ahead, nail pushing device guide card this moment (6) when travelling forward, the vertical at the sheet that is insured (13) rear portion or be bordering on vertical sheer face and block can not move ahead; When loading onto nail cartridge component (2), safety plate (13) is followed closely cartridge component and is depressed, and at this moment, nail pushing device guide card (6) can travel forward under the drive of trigger, finishes firing action; After finishing firing action, nail pushing device guide card (6) moves backward, act on forward inclined-plane of safety plate (13) or cambered surface, safety plate is depressed, can cross safety plate backward resets, after the nail pushing device guide card resets, because the nail cartridge component after using, can not be again to the downward application of force of safety plate, so safety plate (13) pops up under the effect of lower elastomers (12) again, retaining can not travel forward it and finishes firing action in nail pushing device guide card (6) the place ahead, have only load onto new nail casket again after, just can depress safety plate and finish firing action.
This utility model can guarantee only just can operate after the nail cartridge component is by correct the installation, and after being finished firing action, the nail cartridge component promptly can not pull the trigger once more, can prevent the mistake percussion on the one hand, can guarantee to make the nail cartridge component disposablely to use on the one hand, can not be repeated percussion.
