LOCKABLE GAGE FOR OPERATIONS ON TEMPORAL BONE

摘要

FIELD: medicine; medical equipment. SUBSTANCE: gage is a handle. One end of the handle is provided with a plate positioned at an angle relative to the handle. The plate has one central hole and three peripheral holes differing in their diameter. The peripheral holes are equidistant from each other, and the central hole is the center of the circumference on which they are located. There are grooves running around the holes. The gage is provided with a lock. One end of the lock has a barb identical in size with the central hole, and there is a platform with two bulges on the other end of the lock positioned at an angle relative to its axis. the bulges end with two barbs, and the diameter of the distal barb complies with the diameter of the central hole of the plate. The diameter of the proximal barb complies with the diameter of the peripheral holes. The distance between the proximal and distal barbs is identical to the distance between the central hole and the peripheral holes of the plate. EFFECT: convenience in operation.
