Problems solved by technology
Such an operation method has the following disadvantages: because the stapler has a large surface area when it is put in, it is difficult to put the anvil into it; and it is easy to cause the mucosal tissue in the inner cavity of the tissue to be pushed in. Mucosal tissue is not pinned, leading to the potential for various postoperative complications

Embodiment Construction
[0034] Embodiments according to the present invention will be described in detail below in conjunction with the accompanying drawings. It should be pointed out that these drawings are only schematic and not necessarily drawn to scale, and do not limit the protection scope of the present invention.
[0035] figure 1 A schematic structural view of the stapler according to the present invention is shown. like figure 1 As shown, the stapler includes: an anvil assembly 1 , a staple cartridge assembly 2 , a connection assembly 3 , a firing assembly 4 , a transmission assembly 5 , a movable handle 6 , a fixed handle 7 and an adjustment assembly 8 . For the sake of convenience, in the following description, the side close to the operator will be called the proximal end (that is, the side where the adjustment assembly 8 is located), and the side far away from the operator will be called the distal end (that is, the abutment assembly 1 the side on which it is located).

The invention provides a nail pushing seat assembly capable of inclining laterally and resetting and an anastomat adopting the same. The nail pushing seat assembly comprises a nail pushing seat (9), a limiter (10) and a connecting part used for movable connection, wherein a compression spring (15) is arranged between the limiter (10) and the mail pushing seat (9); when the anastomat is in a working state, the limiter (10) is clamped at the connection part of the nail pushing seat (9) and the anastomat to maintain the nail pushing seat (9) to be vertical; and after the anastomat is operated, the limiter (10) moves away from the connection part of the nail pushing seat assembly and the anastomat so that the nail pushing seat assembly can incline laterally, and the compression spring (15) is compressed. The nail pushing seat assembly capable of inclining laterally and resetting and the anastomat disclosed by the invention have a simple structure respectively; when the nail pushing seat assembly and the anastomat are put into or taken out of human tissues, the profiles are smaller so that harm to human tissues and the connection part is avoided, and the operation is safe and convenient.
Description
technical field [0001] The present invention relates to medical equipment, more specifically, to a nail anvil assembly and a stapler using the nail anvil assembly. Background technique [0002] Stapler is a medical device that replaces traditional manual suturing in surgery. Among them, tubular staplers are widely used in human digestive tract operations, such as end-to-end or end-to-side anastomosis of esophagus, stomach, duodenum, and small intestine in the digestive tract. Especially in the case that the operated interface part is relatively short or the line of sight is not clear, it is more necessary to use a stapler to realize the suturing of the wound. In surgical operations such as digestive tract reconstruction, the use of medical staplers to assist incision suture has the advantages of simple operation, rapid suturing, and basically no side effects and complications. [0003] It is well known that a high-quality anastomotic technique is the key to determining the...
