surgical assembly for the implantation of an implantable device in a cavity formed in an osseous structure, comprising abase template intended to be fixed to the osseous structure and a plurality of interchangeable templates intended to be successively coupled to the base template, each of the interchangeable templates having at least one through opening to be used for guiding of a tool to form the cavity in the osseous structure and/or position of the implantable device into the cavity. ## Claims ### Claim 1 A surgical assembly for the implantation of an implantable device in a cavity formed in an osseous structure, comprising a base template designed to be fixed to the osseous structure and a plurality of interchangeable templates intended to be successively coupled to the base template, each of the interchangeable templates having at least one through opening to be used for guiding of a tool to form the cavity in the osseous structure and/or for positioning of the implantable device into the cavity, wherein the base template comprises a receiving portion for the coupling of each one of the plurality of interchangeable templates to the base template, said receiving portion having a reference surface for specifically positioning each one of the plurality of interchangeable templates relative to the base template, and wherein the assembly further comprises a retaining element to securely fasten each of the plurality of interchangeable templates relative to the base template. ### Claim 2 (depends on 1) The surgical assembly of claim 1, wherein the plurality of interchangeable templates comprises at least one drilling template having at least one through drilling opening to be used for guiding of a drilling tool to form the cavity in the osseous structure. ### Claim 3 (depends on 2) The surgical assembly of claim 2, wherein the drilling template comprises a plurality of drilling openings, at least two of the drilling openings being arranged with an overlap to one another. ### Claim 4 (depends on 2) The surgical assembly of claim 2, wherein the drilling template comprises a drilling opening having a cylindrical shape with dimensions fit to guide a drilling bur. ### Claim 5 (depends on 1) The surgical assembly of claim 1, wherein the plurality of interchangeable templates comprises at least one implantation template having at least a through implantation opening shaped for guiding the positioning of the implantable device into the cavity. ### Claim 6 (depends on 5) The surgical assembly of claim 5, further comprising an implanting tool intended to be used for implanting the implantable device in the cavity with the guiding of the implantation opening. ### Claim 7 (depends on 6) The surgical assembly of claim 6, where the implanting tool comprises a first part comprising a lever for rotating the implanting tool, and a second part coupled to the first part at a first end and coupled to the implantation template on an other end, wherein the couplings are designed so that a rotation of the lever imparts a translation movement a rotation movement, or both a rotation and translation movement of the implantable device. ### Claim 8 (depends on 5) The surgical assembly of claim 5, wherein the implantation template further comprises at least one through drilling opening to be used for guiding of a drilling tool to form a further hole in the osseous structure, said drilling opening being non-parallel to the implantation opening and arranged so that the hole can be drilled up to the cavity. ### Claim 9 (depends on 8) The surgical assembly of claim 8, wherein the implantation template further comprises a locking element intended to cooperate with a corresponding recess provided in the implantable device to secure the positioning of the implantable device relative to the implantation template. ### Claim 10 (depends on 1) The surgical assembly of claim 1, wherein at least one of the interchangeable templates comprises a reference protrusion intended to cooperate with a surface of the cavity formed in the osseous structure to further secure positioning of said interchangeable template relative to the base template fixed in the osseous structure. ### Claim 11 (depends on 1) The surgical assembly of claim 1, wherein at least one of the interchangeable templates comprises at least one complementary through opening for evacuation of osseous chips being formed upon drilling of the osseous structure. ### Claim 12 (depends on 1) The surgical assembly of claim 1, wherein the base template has a groove for receiving the retaining element, the retaining element has a protruding portion and each of the plurality of interchangeable templates comprises a recess, said protruding portion being insertable within the recess of any interchangeable template been positioned in the receiving portion of the base template in order to lock said interchangeable template relative to the base template. ### Claim 13 (depends on 12) The surgical assembly of claim 12, wherein the retaining element comprises an arc member rotatively coupled to a cylindrical portion of the base template. ### Claim 14 (depends on 1) The surgical assembly of claim 1, wherein the base template comprises an evacuation opening provided through the reference surface of the receiving portion, said evacuation opening being preferably larger than the through opening of the interchangeable templates to ease evacuation of osseous chips being formed upon drilling of the osseous structure. ### Claim 15 (depends on 1) The surgical assembly of claim 1, wherein the receiving portion of the base template comprises a cylindrical portion with a flat ring arranged at one end of said cylindrical portion to form the reference surface, and wherein the interchangeable templates comprises a cylindrical portion having dimensions to closely fit the dimensions of the cylindrical portion of the receiving portion in order to be positioned therein. ### Claim 16 (depends on 15) The surgical assembly of claim 15, wherein the interchangeable templates further comprises an elongated portion protruding from the cylindrical portion of the interchangeable template, and wherein the cylindrical portion of the receiving portion of the base template comprises a lateral opening to receive said elongated portion of the interchangeable template. ### Claim 17 (depends on 1) The surgical assembly of claim 1, further comprising a drilling tool having at least a drilling bur, wherein said drilling bur comprises a stop element provided at a specific position along its elongated axis so as to mechanically limit penetration of the drilling bur into the osseous structure. ### Claim 18 (depends on 1) The surgical assembly of claim 1, wherein the reference surface is designed to form a surface of contact with the interchangeable template for spreading stress transmitted from the interchangeable template to the osseous structure when the cavity is formed or the implantable device is positioned in the cavity. ### Claim 19 A surgical assembly for the implantation of an implantable device in a cavity formed in an osseous structure, comprising a base template designed to be fixed to the osseous structure and a plurality of interchangeable templates intended to be successively coupled to the base template, each of the interchangeable templates having at least one through opening to be used for guiding of a tool to form the cavity in the osseous structure or for positioning of the implantable device into the cavity, wherein the base template comprises a receiving portion for the coupling of each one of the plurality of interchangeable templates to the base template, said receiving portion having a reference surface for specifically positioning each one of the plurality of interchangeable templates relative to the base template, said reference surface being designed to form a large surface of contact with the interchangeable template for spreading stress transmitted from the interchangeable template to the osseous structure when the cavity is formed or the implantable device is positioned in the cavity, and wherein the assembly further comprises a retaining element to securely fasten each of the plurality of interchangeable templates relative to the base template.
