Problems solved by technology
[0005] When taking out the anvil, the anvil cap needs to pass through the suture opening; however, after the stapler sutures, the diameter of the suture opening between the two parts of the tissue is smaller than the diameter of the anvil cap, and the anvil cap can easily close the suture opening when it passes through the suture opening. The staples used for suturing are stretched apart, destroying the suture, damaging the suture tissue, and causing medical accidents
[0006] In addition, for some operations, due to the small space for specific tissues, tissue damage will also be caused when the anvil is placed

The invention relates to the technical field of medical instruments and discloses a surgical instrument and a nail anvil thereof. The nail anvil comprises a nail anvil rod, a nail anvil cap and an execution mechanism, the nail anvil cap comprises at least two nail anvil leaves, each nail anvil leaf is connected to the nail anvil rod in a pivoted manner and can be folded in the direction of axis of the nail anvil rod, and the execution mechanism is in transmission connection with a driving mechanism of the surgical instrument and drives each nail anvil leaf to be folded or unfolded during action. The execution mechanism can drive each nail anvil leaf to be folded in the direction of axis, diameter of the nail anvil cap after being folded is small, and trauma to a suturing opening when the nail anvil is taken out through the suturing opening or trauma to tissue when the nail anvil is placed in is small, so that surgical safety is improved.
Description
technical field [0001] The invention relates to the technical field of medical instruments, in particular to an anvil of a surgical instrument and the surgical instrument. Background technique [0002] When performing surgical operations on tissues such as the esophagus, stomach, and intestinal tract, surgical instruments such as circular staplers are often used. The stapler can shorten the operation time and improve the operation efficiency. [0003] The circular stapler adopts the axial inward suture method during the operation, and forms a suture ring inside the two sections of tissue, which can make the body bleeding generated during the operation be discharged together with the contents, and the body tissue is easier to heal after the operation. [0004] The circular stapler includes an anvil with an anvil cap and an anvil rod, and a body with a nail box. During the operation, the anvil cap of the nail anvil is located in a tubular tissue to be sutured, and the nail box...
