Description

The invention relates to medical technology, in particular to osteotomes

The aim of the invention is the atraumatic cleavage of the inner cortical plate.

FIG. 1 shows an osteotoma left side view; in fig. 2 - an osteotome of a lev, front view; in fig. 3 - left osteotome, top view; in fig. 4 - left osteotome, isometric view; in fig. 5 - right osteotome, side view; in fig. 6 - right osteotome, front view; in fig. 7 - right osteotome, top view; in fig. 8 - right osteotome, isometric view.

Osteot for resection of the internal cortical plate of the lower jaw contains blade 1, handle 2 and transitional part 3. The osteote is provided with an additional blade A, and the transitional part is made in the form of shoulder 5 and arc 6, with blade 1 and A relative to handle 2 mounted console, at equal distance from her.

According to the location of the arm 5 and the arc 6, the proposed osteotomes are conventionally distinguished into left (Figs. 1-4) and right (Figures 5-8).

; Osteote works as follows

Depending on the side of the lesion, right or left osteotomes are introduced into the oral cavity. Before the insertion into the oral cavity, the cortical holes (or incisions) are made by the drill and the cortical plate of the mandible is split off with an impact on the handle of the osteotome.

The use of the proposed osteotome, compared with the known, results in therapeutic effects: thanks to the sharpening angle of the blades and the presence of a bogus-shaped (bayonet-shaped) removal that facilitates the workability in the oral cavity, less traumatic cleavage of the cortical plate is achieved, which leads to reduction of complications and accelerated healing.
