7 results about "Stapled anastomosis" patented technology

This invention discloses a staple cartridge assembly and a surgical instrument. The staple cartridge assembly includes a staple cartridge body with a cutting groove dividing it into two parts. Each part includes a staple exit surface with two rows of staple cavities arranged longitudinally, designated as a first row and a second row. Multiple anastomotic staples are disposed within each staple cavity, with the staple crowns arranged in an arc shape. Each staple cavity in the first row is arranged along a first arc, and each staple cavity in the second row is arranged along a second arc. The distance between the endpoints of the first and second arcs in the lateral direction is less than or equal to 0.5 mm, and the radii of the first and second arcs are greater than or equal to 1.5 mm and less than or equal to 8 mm. By optimizing the arrangement of the staple cavities to reduce the lateral width of the staple cartridge assembly, the width of the jaw assembly is reduced, facilitating the jaw assembly's entry into the body through the gap between adjacent ribs, thus simplifying surgery and reducing patient discomfort.

The present application relates to the field of medical devices, in particular to a preloaded reinforcing sheet and a staple cartridge assembly for a stapler. The preloaded reinforcing sheet is provided with a group of protruding structures, the protruding height of the group of protruding structures is 0.1-1.5 mm, to provide a new preloading method for the anastomotic reinforcing sheet. The structure and shape of the preloaded reinforcing sheet are improved at the physical level. The preloaded reinforcing sheet and the staple cartridge arm are fixed, and the anastomotic staples are stably constrained in the staple groove. In the scene of using the stapler to clamp the tissue but not firing the stapler, or in the process of releasing the preloaded reinforcing sheet, the preloaded reinforcing sheet is extruded by the tissue and the staple cartridge arm of the stapler, so that the reinforcement of the anastomotic port changes from "passive covering" to "active adaptation". The reinforcing sheet naturally extends and adapts to the tissue along the tissue tension direction when stressed, realizes dynamic stress dispersion, improves the tear resistance of the material in the hydrated state, and also does not affect the stapling effect of the anastomotic staples due to the wrinkles formed by extrusion.

The embodiment of the present disclosure provides a staple cartridge assembly and a stapler, the staple cartridge assembly comprises a staple cartridge configured to accommodate an anastomosis staple, the staple cartridge has a staple cartridge end face; a patch comprising a first body part and a first connecting part, the first body part covers the staple cartridge end face, and the first connecting part is provided with a first connecting hole penetrating a surface thereof; a tubular connecting piece connected with the staple cartridge, an internal part of the tubular connecting piece is provided with a pushing device, and the pushing device is configured to make the anastomosis staple penetrate the staple cartridge end face; and a patch connecting piece sleeved on an external part of the tubular connecting piece and configured to stably connect the patch with the staple cartridge, wherein an external lateral wall of the staple cartridge is provided with a relief part configured to accommodate at least part of the patch connecting piece to reduce a gap between the first connecting part and the staple cartridge and avoid a patch surface wrinkle under external force to affect suturing and recovery of an anastomosis port.

The utility model discloses a kind of staple cartridge structure and anastomat with staple cartridge structure, the staple cartridge structure includes cartridge body, the cartridge body includes upper surface, two end portions, the outer side wall of connecting two end portions, anastomosis face, slot and multiple nail cavities;Anastomosis face is located upper surface and is divided into left and right two anastomosis areas;Slot is located between two anastomosis areas, and extend longitudinally from upper surface downward and extend horizontally between two end portions;Each nail cavity has opening face, and each staple cartridge is equipped with anastomosis nail;Multiple staple cartridge slots extend downward from any one anastomosis area, and each staple cartridge slot extends horizontally from slot to outer side wall. The anastomat includes the above-mentioned staple cartridge structure and the nail seat, and the staple cartridge structure and the nail seat are connected with each other. The utility model is by being set up staple cartridge slot on the anastomosis face of cartridge body, realizes the liquid inside to be excluded to anastomat outside, improves the reliability of staple cartridge structure anastomosis, and can reduce the risk of tissue being crushed.

The application provides a crank rotatable blood vessel anastomat capable of providing a good surgical field, comprising a firing mechanism, a crank transmission mechanism and an anastomat nail pushing and forming mechanism; the firing mechanism is configured to drive the crank transmission mechanism and push the anastomat nail pushing and forming mechanism to complete anastomat nail forming and blood vessel anastomosis; the crank transmission mechanism is configured to avoid the occlusion of the rear part of the anastomat and the operating hand to the surgical field through rotation of the crank, and assist in finding a suitable angle for use of the anastomat; the anastomat nail pushing and forming mechanism is configured to complete anastomat nail forming and blood vessel anastomosis under the pushing of the crank transmission mechanism; the firing mechanism drives the crank transmission mechanism, which can push the anastomat nail pushing and forming mechanism to complete anastomat nail forming and blood vessel anastomosis; meanwhile, the crank transmission mechanism can avoid the occlusion of the rear part of the anastomat and the operating hand to the surgical field, and rotation of the crank transmission mechanism can further assist in finding a suitable angle for use of the anastomat.
