Embodiment Construction
[0026] In order to make the above objects, features and advantages of the present invention more comprehensible, specific implementations of the present invention will be described in detail below in conjunction with the accompanying drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. However, the present invention can be implemented in many other ways different from those described here, and those skilled in the art can make similar improvements without departing from the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.
[0027] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to t...

The invention relates to a linear cutting anastomat. The linear cutting anastomat comprises a housing, an input shaft, a trigger rod, a closing rod and a nail pushing plate. Before the linear cutting anastomat is closed up, the trigger rod and the closing rod are connected together, and when the input shaft rotates, the trigger rod and the closing rod advance simultaneously till closing is completed. After the closing is completed, the trigger rod and the closing rod are separated, and when the input shaft continues to rotate, the closing rod is kept static, the trigger rod continues to move forwards till the triggering process is completed. Therefore, compared with a traditional linear cutting anastomat mainly replying on connecting-rod movement among multiple parts to achieve closing and a triggering distance, the parts which the linear cutting anastomat relies on are fewer, the linear cutting anastomat does not need to excessively rely on the precision of the parts, therefore control errors of the closing and the triggering distance are smaller, and application is facilitated.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to a linear cutting stapler. Background technique [0002] The medical stapler is a medical device that is often used in performing surgical operations on the physiological tissues of the digestive tract. In general surgery, the stapler is often used to complete the cutting and closing functions of the tissue. The working principle of the stapler is to place the tissue between the staple cartridge and the anvil head, and to squeeze the tissue reasonably by adjusting the distance between the staple cartridge and the anvil head. When the distance between the staple cartridge and the anvil head reaches the effective When the suture is in the safe range, the U-shaped staple is compressed into a B-shape to suture the tissue, and small blood vessels can pass through the gap of the B-shaped staple to ensure the blood supply of the anastomosis and the distal tissue.
