摘要：
The invention relates to medical engineering, in particular to devices used in the surgical treatment of chronic dacryocystitis in ophthalmic practice. The purpose of this utility model is to provide a device enabling proper bone formation and window shapes with smooth edges, preventing injury to the nasal mucosa, reducing the number of recurrences. This object is achieved in that the rod is introduced into the housing and a circular swirl motion is controlled depth and degree of its protrusion with respect to the cutter. The utility model is illustrated by drawings, where Fig. 1 is a diagram of a device for forming a bone hole when the outside dacryocystorhinostomy, wherein FIG. 1 Pos. 1 - the handle, Fig. 1 Pos. 2 - housing, FIG. 1 Pos. 3 - thread on the inner surface of the housing, which is screwed cutter, FIG. 1 Pos. 4 - rod, FIG. 1 Pos. 5 - cutter. Drilling diameter of 9 to 13 mm, depending on the cutter size. The cutter diameter 1/2 or 1/3 of a circle that allows the formation of bony window is not immediately in a circle, and small areas - an important point in the prevention of damage to the nasal mucosa, reduction of skin incision and increase the surgical wound viewing device operates as follows. In the formation of the bone hole when dacryocystorhinostomy cutter screwed into the body and then inserted into the housing the rod, the rod extends through the housing and the cutter, thus, the rod serves to mark the center of the future bone hole and fixing the device in the intended bone point where there will be drilled window. The required depth of penetration into the bone governed by rotational movements of the rod. Depending on the desired diameter of the drill, you can choose the right size cutters. Offered as a useful model trepanofreza has the following positive effects:- convenience and ease of use,- reducing the time required to perform trephination to 1 min- burr hole has a flat, smooth edges without ridges and bone fragments.- reducing the skin in
