The application discloses a punching device with notch trimming function for anastomat titanium nail production, and relates to the technical field of metal punching, which comprises a bending unit and an anti-abrasion unit. The bending unit comprises force applying blocks and a force receiving block, and the anti-abrasion unit comprises a rotating block and a roller. After the titanium nail is punched by a hydraulic cylinder, the titanium nail is conveyed to the bending unit. When the titanium nail is bent, the force applying blocks on both sides of the force receiving block move synchronously to the force receiving block. The titanium nail column surface generates a pushing force on the roller on the rotating block. Because the rotating block is rotationally connected with the force applying block, the rotating block rotates around the connecting point until the rollers arrayed in the rotating block completely adhere to the titanium nail column surface, that is, the two sides of the titanium nail are bent by 90 degrees. In the bending process, the roller on the rotating block converts the traditional sliding friction into rolling friction, effectively reduces the abrasion of the titanium nail surface, avoids the emergence of defects such as burrs and micro-cracks, and reduces the risk of intraoperative tissue damage and the possibility of postoperative inflammatory reaction.

This invention relates to the field of medical devices, specifically to a non-fastener-based patch attachment method and device. The patch is attached to at least one anastomosis arm of a stapler via a non-penetrating connector, allowing the patch to be non-penetratingly connected to the anastomosis arm. The anastomosis arm and patch achieve a mechanical self-locking connection and engagement without traditional fasteners through low normal force, normal support force, shear resistance, and / or friction, significantly reducing the risk of patch tearing associated with traditional fasteners. When the stapler is not fired, the constraint effect of this non-penetrating connector on the patch stably fixes the patch to the anastomosis arm, ensuring no relative displacement. Simultaneously, it avoids damage to surrounding tissue caused by the connector penetrating the patch during the stapler's delivery to the target location.

This invention relates to an anastomosis device for gingival surgical incisions, comprising a main body structure, a gripping structure, several staple structures, a staple delivery structure, two power structures, and a staple separation structure. Its advantages lie in that, by rotating the gripping structure to the main body structure, the gripping structure drives the two power structures to move along the length of the main body structure, pressing the staple separation structure towards the staple structure, thus separating the staples; simultaneously, the power structures push the separated staple structures, causing them to move along the staple delivery structure. The staple delivery structure clamps both sides of the surgical incision and deforms the staple structures, separating them from the staple delivery structure, thereby compressing both sides of the surgical incision and achieving anastomosis. This eliminates the need for staples to puncture the gums, reducing trauma, and is simple and convenient to operate. It allows for rapid suturing of surgical incisions, and the protruding staple delivery structure allows for anastomosis of gums deep within the oral cavity.
