1. A surgical device for elevating the Schneiderian membrane, comprising:
a main portion of said surgical device for said elevating of said Schneiderian membrane, including:
a main element having a bended configuration along an unthreaded portion of the main element, wherein said main element comprises:
an adjustment portion including an outer thread along said adjustment portion, wherein a diameter of said adjustment portion is bigger than a diameter of said main element of said main portion;a free end located at a first side of said main element;a set of depth measurement marks located in an area of said free end;a first connection section located at a second side of said main element, wherein a bended portion of said bended configuration of said main element has an angle in a range of 90°-180° with respect to the longitudinal axis of the main element at a first bended location located in an area of said main element between said outer thread and said first connection section, and the bended portion has an angle in the range of 0°-150° with respect to the longitudinal axis of the main element at a second bended location located in an area of said main element between said outer thread and said first bended location;an adjustment element, comprising:
a cylinder located between the second bended location and the set of depth measurement marks, the cylinder including an inner thread along said cylinder, wherein said inner thread is coupled with said outer thread of said adjustment portion of said main element;a first projection extended from said cylinder;a second projection extended from said cylinder and diametrically opposed from said first projection, wherein said first and second projections each have a longitudinal axis parallel to a longitudinal axis of the cylinder, and said first and second projections are configured to rest on a lower surface of a patient's gum; a handle portion of said surgical device for said elevating of said Schneiderian membrane including a handle element comprising a second connection section located at a first end of said handle portion, wherein said second connection section is coupled with said first connection section of said main element of said main portion by a threaded coupling, and wherein said handle portion includes a texture on an outer surface of said handle element of said handle portion, and wherein said texture is located in an area of a second end of said handle portion, and wherein said second end of said handle portion is located opposite to said first end of said handle portion. |
