DEVICE FOR BITE WOUNDING IN EXPERIMENT Russian patent published in 2014 - IPC G09B23/28 A61B17/28 

FIELD: medicine.

SUBSTANCE: what is presented is a device which comprises two handles with branches at working ends of which provided is a line of teeth with pointed tops and a widened base. The teeth are arranged on a semi-circumference on an anterior working surface and at edges of the branches. When closed, tops of the anterior teeth of the upper branch are arranged in front of the tops of the teeth in the lower branch. Tops of the side teeth of the upper branch project into a lumen between the tops of the side teeth of the lower branch. Each branch between the lines of the teeth comprises a calibrated long window at its greater edge; the last tooth is followed by a notch forming a lumen between tooth-free surfaces of the branches when closed. Preferentially, between the handles there is a plate spring holding the handles separated apart to be brought together until the teeth of the upper and lower branches close. One end of the plate spring is attached to an internal surface of an end of the upper handle, while the other end of the spring is provided on an internal surface of the middle portion of the lower handle and sliding longitudinally thereon.

EFFECT: uniform bite wound simulation in all experimental groups by increasing more accurate localisation, form, size and nature of a multiple wound that increases the quality of comparative analysis of various wound healing techniques.
