- the secondary side surface 30b forms a rounding forming a continuous junction between the rear surface 32b and the front surface 34b.
- Each tooth 14a is adjacent to a tooth 14b, and vice versa.
- the rear surface 32a of a tooth 14a is joined to the primary side surface 28b of an adjacent tooth 14b so as to form a concavity.
- the front surface 34a of the tooth 14a is also connected to the primary side surface 28b of another tooth 14b which is adjacent to it, so as to form a concavity.
- the apex 26a and the secondary side surface 30a of the tooth 14a are located between the respective primary side surfaces 28b of these two adjacent teeth 14b.

- two teeth 14a, 14b adjacent to each other have respective primary side surfaces 28a, 28b which intersect in a section view of the first jaw 2 along a section plane parallel to the axis of pivoting X. This is particularly verified in the first section plane (that of FIG. 7) and the second section plane (that of FIG. 9) discussed previously.
- Such an arrangement promotes a more effective multidirectional grip of the teeth 14 on the biological tissue pinched by the staple 1.
- the point of intersection of the surfaces 28a, 28b in this view is located at mid-width of the first jaw 2, this width of the jaw being measured in a direction parallel to the pivot axis X.
- the interlacing discussed above is applicable to any pair of adjacent teeth 14a, 14b of the first jaw 2, and any pair of teeth 16a, 16b of the second jaw.
- a tooth 14a and a tooth 16a facing each other delimit between them a space forming a baffle, when the clip is closed. This is also true for a pair of mutually facing teeth 14b, 16b. Tissue pinched by Staple 1 extends into this space.
- the outer surface 20, opposite the inner surface 18 discussed above, is intended to be found opposite the bottom of a groove of the applicator A.
- the outer surface 20 is a convex curved surface.
- the lateral surface 22a of the first jaw 2 comprises a surface portion 36a which is connected to the internal surface 18 at the edge 24a.
- the surface 36a has a tangent, at a point on the edge 24a, which is inclined by an angle a with respect to an axis parallel to the pivot axis X.
- the angle a is non-zero and strictly less than 90 degrees. This thus makes it possible to make the edge 24a more prominent.
- the angle a is less than or equal to 80 degrees, or even less than or equal to 70 degrees. This angle ⁇ is encountered in particular in the first cutting plane of FIGS. 7 and 11, and/or in the second torque plane of FIG. 9).
- the surface 36a can present in a section plane a rectilinear profile in the torque plane considered.
- the side surface 22a also comprises a surface portion 38a which is connected to the outer surface 20, for example continuously, that is to say without forming an edge with the outer surface 20.
- the side surface 22a further comprises an intermediate surface portion 40a.
- the intermediate surface portion 40a forms with the surface portion 36a a longitudinal groove 42a extending between the connection 3 and the free end of the first jaw 2.
- the intermediate surface portion 40a forms with the surface portion 38a a longitudinal rib 44a extending between the connection 3 and the free end of the first jaw 2.
- the intermediate surface portion 40a is connected to the surface 38a by a longitudinal edge forming on the one hand a crest line of the longitudinal rib 44a and on the other hand an edge of the longitudinal groove 42a.
- side surface 22b includes a surface portion 36b which is joined to inner surface 18 at ridge 24b.
- the surface 36b has a tangent, at a point on the edge 24b, which is inclined by an angle ⁇ with respect to an axis parallel to the pivot axis X.
- the angle ⁇ is non-zero and strictly less than 90 degrees. This thus makes it possible to make the edge 24b more prominent.
- the angle ⁇ is less than or equal to 80 degrees, or even less than or equal to 70 degrees. This angle ⁇ is encountered in particular in the first cutting plane of FIGS. 7 and 11, and/or in the second torque plane of FIG. 9).
- the surface 36b can present in a section plane a rectilinear profile in the torque plane considered.
- the side surface 22b also comprises a surface portion 38b which is connected to the outer surface 20, for example continuously, that is to say without forming an edge with the outer surface 20.
- the side surface 22b further comprises an intermediate surface portion 40b.
- the intermediate surface portion 40b forms with the surface portion 36b a longitudinal groove 42b extending between the connection 3 and the free end of the first jaw 2.
- the intermediate surface portion 40b forms with the surface portion 38b a longitudinal rib 44b extending between the connection 3 and the free end of the first jaw 2.
- the intermediate surface portion 40b is connected to the surface 38b by a longitudinal edge forming on the one hand a crest line of the longitudinal rib 44b and on the other hand an edge of the longitudinal groove 42b.
- the surfaces 36a, 36b widen relative to each other up to the edges 24a, 24b in a direction going from the external surface 20 towards the internal surface 18.
- the width of the first jaw measured in a direction parallel to the pivot axis X increases, when the surfaces 36a, 36b are traversed towards the edges 22a, 22b.
- Such a widening allows the formation of more salient angles at the level of the edges 24a, 24b.
- These edges 24a, 24b form two edges of the inner surface 18 intended to be in contact with a biological tissue pinched between the jaws 2, 4 of the staple. Consequently, the ridges 22a, 22b can catch the biological tissue. Making them more prominent improves this grip.
- inner surface 18 and side surface 22a form at ridge 24a an angle of less than 100 degrees in a cutting plane of the jaw passing through the inner surface. 18, the outer surface 20 and the two side surfaces 22a, 22b.
- the internal surface 18 and the lateral surface 22b form at the edge 24b an angle less than 100 degrees in a cutting plane of the jaw passing through the internal surface 18, the external surface 20 and the two lateral surfaces 22a, 22b.
- Such angles are found in particular in the first section plane and in the second section plane. Note that these angles would be further reduced in embodiments (not shown) in which surface 18 is flat and parallel to pivot axis X (ie, in the absence of teeth 14).
- the surfaces 38a, 38b approach each other as far as the outer surface 20, in a direction going from the inner surface towards the outer surface 20. This rimpedement begins at the level of the ribs 44a, 44b. This bringing together gives the jaw a tapered profile on the outside. With such a tapered profile, the first jaw tends to get less stuck in the applicator, compared to a jaw with a rectangular profile.
- the presence of the surfaces 40a, 40b makes it possible to obtain both the widening near the edges 24a, 24b and the tapered profile at the level of the external surface, without however significantly increasing the width of jaw 2.
- the second jaw 4 has an outer surface comprising the same characteristics as the outer surface 20 of the first jaw 2;
- the second jaw 4 has two side surfaces comprising the same characteristics as the side surfaces 22a, 22b of the first jaw 2.
