Anastomat with nail anvil fitting suturing nail bending structure

Abstract

The invention discloses an anastomat with a nail anvil fitting suturing nail bending structure, and belongs to the technical field of medical instruments. The anastomat is characterized by comprising an anastomat body, a nail bin assembly and a nail anvil block, the nail bin assembly and the nail anvil block are fixedly connected to the left side of the anastomat body, and a guide shaft rod is slidably connected to the inner wall of the anastomat body; the guide shaft rod sequentially penetrates through the anastomat body and the nail bin assembly from right to left and rotates at the center of the inner wall of the nail anvil block, the nail bin assembly comprises a nail bin shell, two nail pushing seats are arranged on the left side of the nail bin shell, and the diameter of the outer-ring nail pushing seat is larger than that of the inner-ring nail pushing seat; the width of the inner-ring nail pushing seat is larger than that of the outer-ring nail pushing seat, and two sets of nail outlet parts are arranged on the inner wall of the inner-ring nail pushing seat, the situation that when a suturing nail is used for suturing a wound of a patient, the suturing nail deforms and inclines, the anastomosis effect is affected can be prevented, and the hemostasis effect of the anastomosis position is improved.

Description

technical field [0001] The present invention relates to the technical field of medical devices, and more particularly, to a stapler with a staple anvil and a stapling staple bending structure. Background technique [0002] The principle of the medical stapler is that in surgical operations, several rows of staples are stapled to the tissue to be sutured by an instrument similar to the structure of a stapler to replace the original suture and needle suture, which has a short suture time, The suture is uniform and the healing effect is good. [0003] In the staple forming technology, the staple pusher pushes out the staples formed on the staple anvil, the staples may be displaced by the extrusion and rejection of the sutured tissue at the beginning of being pushed out of the staple groove, and it is necessary to The lack of locking force at the sutured tissue can easily lead to insufficient blood supply at the suture and poor hemostatic effect. Therefore, those skilled in the...

Problems solved by technology

[0003] In the staple forming technology, the staples formed on the anvil are pushed out by the staple pusher, and the staples may be offset by the extrusion and repulsion of the sutured tissue at the beginning of being pushed out of the nail groove, and the required The lack of locking force at the sutured tissue is more likely to lead to insufficient blood supply at the sutured site and poor hemostatic effect. Therefore, those skilled in the art have provided a stapler with an anvil-fitting staple bending structure to solve the above background questions raised in technology
