Linear cutting anastomat under bendable endoscope and assembly of linear cutting anastomat

Abstract

The invention discloses a linear cutting anastomat under a bendable endoscope and an assembly of the linear cutting anastomat. The linear cutting anastomat comprises an anastomat jaw, a steering connecting block, an assembly inner core and a cutting knife assembly. The assembly inner core comprises an inner core shell and an inner core connecting block fixedly installed in the inner core shell. The front end of the steering connecting block is hinged to the rear end of the anastomat jaw, a first vertical rotating shaft is formed at the hinged position, the rear end of the steering connecting block is hinged to the front end of the inner core connecting block, and a second vertical rotating shaft is formed at the hinged position. The cutting knife assembly penetrates through the inner core connecting block, the steering connecting block and the anastomat jaw and can slide front and back. On the basis of the double rotating shafts (centers), U-shaped left and right bending pieces are adopted, and the bending process is controlled through steering of the inner core connecting block. Through the arrangement, the bending radius can be increased, the percussion force in the cutting and anastomosis process is reduced, and a doctor has a better operation hand feeling; and meanwhile, a larger bending angle can be achieved, so that a doctor has a better operation space.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a bendable laparoscopic linear cutting stapler and components thereof. Background technique [0002] Laparoscopic staplers play the most critical role in surgery. Due to the limitation of the space in the abdominal cavity or the thoracic cavity, the traditional linear endoscopic stapler cannot fully and effectively reach the required surgical site for clamping, transection, and anastomosis of tissues. seat) bendable elbow stapler. In a straight line state, this bendable elbow stapler enters the thoracic cavity or abdominal cavity through the puncture device, controls the jaws of the stapler to bend at a certain angle through the bending control mechanism on the handle outside the body, and clamps and transects the surgical site , anastomosis and a series of operations. After the operation is completed, it becomes straight again and exits the body. [0003] When operating th...

AI Technical Summary

Problems solved by technology

In the above-mentioned structure, when the cutting and anastomosis are fired in the bending state, a large firing force is required, which affects the feeling of medical operation, and the left and right swing angle of the jaws of the stapler is limited, so that in some operations such as clamping, transection, and anastomosis A series of operations cannot achieve the ideal operating position, and cannot be suitable for medical treatment under more complex clinical conditions
