A Surgical clamping device (10) includes a first jaw and a second jaw (18, 19) movable relative to the first jaw between a proximal position and a spaced position. The first jaw (19) has a supporting surface (72) toward the second jaw and an opposite surface (74) facing away from the second jaw (18). An insert (22) is removably mountable in an operative position on the first jaw (19) and includes an insert base (90) having a central wall and a pair of sidewalls (110, 112) which form a channel (114) configured to receive the first jaw (19). An elastomeric material (92) forms a pad on the central wall facing the second jaw (18). Holes (102) in the central wall increase the thickness of the pad without increasing the profile of the insert. A detent mechanism (85) extends laterally of the first jaw.

Un dispositif de serrage chirurgical (10) comporte une première mâchoire et une seconde mâchoire (18, 19) pouvant se déplacer par rapport à la première entre une position proximale et une position écartée. La première mâchoire (19) comporte une surface support (72) orientée du côté de la seconde mâchoire et une surface opposée (74) s'écartant de la seconde mâchoire (18). Un élément d'insertion (22) est monté amovible sur la première mâchoire (19) dans une position de fonctionnement, et comprend une base (90) pourvue d'une paroi centrale et d'une paire de parois latérales (110, 112) qui forment une rainure (114) conçue de façon à recevoir la première mâchoire (19). Un matériau élastomère (92) forme un tampon sur la paroi centrale opposée à la seconde mâchoire (18). Des trous (102) ménagés dans la paroi centrale augmentent l'épaisseur du tampon sans agrandir le profil de l'élément d'insertion. Un mécanisme à détente (85) s'écarte latéralement de la première mâchoire (19).
