技术领域technical field
本实用新型涉及医疗器械技术领域，具体的说，是涉及一种推动块设置有限位装置的直线切割吻合器。The utility model relates to the technical field of medical instruments, in particular to a linear cutting stapler with a push block provided with a limiting device.
背景技术Background technique
目前，直线切割吻合器主要适用于胃肠道外科、妇科、胸外科(肺叶切除)和小儿外科(小儿胃、肠道)手术中组织器官的离断切除和吻合，直线切割吻合器一股由抵钉座和带有活动手柄的钉仓组件组成，手术前先将活动手柄打开，将抵钉座和钉仓组件置在待手术的组织两侧后对合，再将活动手柄关闭，将抵钉座和钉仓组件锁紧，然后向前推动击发钮，击发钮连接推动块，推块连接推钉板和切割刀，推钉板将缝合钉推出进行组织缝合，同时切割刀前移将缝合后的组织切断，完成手术。At present, linear cutting staplers are mainly suitable for the resection and anastomosis of tissues and organs in gastrointestinal surgery, gynecology, thoracic surgery (lobectomy) and pediatric surgery (stomach and intestinal tract in children). The nail anvil is composed of a nail anvil and a nail cartridge assembly with a movable handle. The nail base and the staple cartridge assembly are locked, and then the firing button is pushed forward, the firing button is connected with the push block, and the push block is connected with the push plate and the cutting knife, the push plate pushes out the staples for tissue suture, and at the same time, the cut knife moves forward to suture After the tissue is cut off, the operation is completed.
然而，现有的直线切割吻合器的推动块在激发的过程中由于受力较大，会在器械里面歪斜，使整个击发过程中的推钉片推进不处于直线受力状态，进而整体击发力过大，这样不仅影响医生手术手感，更有可能使得击发按钮断裂，进而导致器械失效、手术失败。However, the push block of the existing linear cutting stapler will be skewed inside the instrument due to the large force during the excitation process, so that the pusher piece during the entire firing process is not in a straight line force state, and then the overall firing Excessive force will not only affect the doctor's surgical feel, but may also cause the firing button to break, which will lead to instrument failure and surgical failure.
