Problems solved by technology

[0003] However, the existing staplers for unequal-height staples only improve the height, diameter, and elastic modulus of the staples, and the anvils are adapted only by misalignment for matching with the staples. Different sizes of staples lead to unstable final anastomosis, which affects the operation and postoperative recovery

Abstract

The invention provides a nail abutting seat and an anastomat. A first groove set and a second groove set which are located in the same plane are formed in the nail abutting seat, and the first groove set and the second groove set are symmetrically arranged in the extending direction of the nail abutting seat; the first groove set and the second groove set each comprise at least two rows of grooves parallel to the extending direction of the nail abutting base, and the concave depth of the grooves located on the outer side is larger than that of the grooves located on the inner side. Compared with the prior art, different abutting structures are arranged between the nail bin assembly and the nail abutting base, the grasping force of the nail bin assembly on tissue can be increased when the anastomat conducts anastomosis by increasing the surface area in contact with the tissue, the nail forming effect is better and more stable, and tissue healing is promoted.

Description

technical field [0001] The invention relates to a nail anvil and a stapler, belonging to the field of medical instruments. Background technique [0002] Stapler is a device used in medicine to replace manual suturing. It has the advantages of fast suturing, easy operation, and few side effects and surgical complications. The advantage of the stapler with unequal height nails is that it can provide a superior blood supply environment according to the way the sutured opening is tightened inside and loosened outside, and can promote tissue healing and rapid growth. [0003] However, the existing staplers for unequal-height staples only improve the height, diameter, and elastic modulus of the staples, and the anvils are only adapted to the staples by dislocation. Staples of different sizes lead to an unstable final anastomosis effect, which affects the operation and postoperative recovery. [0004] In view of this, it is necessary to propose a nail anvil and a stapler to solve...
