The projecting portion 517 minimizes the tightening interval between the envelope 410 and the staple cartridge 500 when the envelope 410 and the staple cartridge 500 clamp the surgical site.

The protrusions 517 may have a circular arc shape and protrude straight along the longitudinal direction of the cartridge body or may protrude with a certain distance in the form of embossing.

Of course, the present invention is not limited to this, and the protrusion 517 may not be formed.

4A, the surgical site A disposed on the upper portion of the staple cartridge 500 is divided into two surgical sites by the cutter 600 with reference to the virtual cutting line A0. Is cut. One of the two surgical sites is a first surgical site (C) to be removed, and the other is a second surgical site (B) remaining in the human body.

4B, the first surgical site C has two rows of staple lines parallel to the cut surface A1, and the second surgical site B is parallel to the cut surface A1 I have three rows of staple lines.

 The distance D1 between the first right stapling line 1aa near the cut surface A1 and the cut surface A1 among the staple lines of the first operation site C is smaller than the distance D1 between the second operation site B Of the stapling lines of the first stapling line (3a) close to the cut surface and the cut surface (A1).

The living tissue between the first right-side stapling line 1aa and the cut surface A1 of the first surgical site C is not damaged at all by the staples, which is suitable for the pathology examination.

The distance D1 between the cut surface A1 and the first right stapling line 1aa may be any distance to obtain the tissue for pathological examination. However, the distance D1 between the cut surface A1 and the first right- And has a distance substantially the same as the distance from the second right-hand stapling line to the cutting surface A1 among the lines.

This is because when the surgical site A is cut by the cutter 600, the position at which the staple catches the surgical site A on both sides of the second cutter guide 515, that is, The surgical site A can be cut more stably.

As a result, in the process of cutting and sealing one organ to two regions, the distance to the staple line of the organ to be removed based on the cutting plane is made larger than the distance to the staple line of the surgical site remaining in the human body The cutting margin of the biopsy for biopsy is not damaged at the surgical site. Thereby, it is possible to stably and easily secure a tissue area for pathological examination that is not damaged by the staple at the surgical site of the organs to be removed.
