LOWER JAW PROSTHESIS DEVICE Russian patent published in 2024 - IPC A61F2/28 A61F2/30 

FIELD: medicine.

SUBSTANCE: lower jaw prosthesis device includes a base body made in the form of a pair of rod-shaped parts located at an obtuse angle to each other. At the end of the first rod-shaped part there is a bone plate equipped with a displacement device, and at the end of the second rod-shaped part there is an articular head for fixation in the glenoid fossa of the temporal bone. Articular head is made in the form of a separate body and is equipped with a means of moving the articular head relative to the second rod-shaped part of the basic body. Basic body is made integral and has longitudinal through holes in each rod-shaped part, which cross relative to each other in space and go outside along the ends. Separately, at the base body bending point, the bone plate covers from the outside the first rod-shaped part of the base body, and its movement means is made in the form of a mechanism for stepwise movement of the bone plate, which is mounted inside the longitudinal through hole and the bone plate, and its control means comes out in the place of bending of the base body. Articular head has a rod arranged inside a longitudinal through hole of the second rod-shaped part of the base body. Articular head movement means is made in the form of a mechanism for stepwise movement of the articular head and its control means extends outside at the bend of the base body.

EFFECT: proposed device enables to extend the device in two directions – in length and height (in the area of the body and in the branch, respectively), compactness, ease of use when moving of the device elements, possibility of repeated gradual moving of device elements by the required value, expansion of the range of devices intended for carrying out operations of this type.
