Problems solved by technology

[0003] In clinical practice, the common preoperative design of ear reconstruction is to 3D print the healthy ear. During the reconstruction of the affected ear, the costal cartilage needs to be removed, simulated and sculpted according to the shape and size of the healthy ear, and then placed on the affected side. The specific placement is usually done by It is determined visually, and there is a large error with the actual position; in addition, the existing literature discloses a design measurement of the affected ear before surgery, the specific method is to measure from the outer corner of the eye, due to the asymmetry of the eye itself, this measurement method cannot Ensure horizontal position symmetry, so it is not practical in clinical practice

Abstract

The invention provides a head-face symmetry measuring device and system; the head-face symmetry measuring device comprises a head band and a philtrum line positioning rod, wherein the head band is provided with two graduation segments which are of center symmetry about the midpoint of the head band; the philtrum line positioning rod is connected directly or indirectly with the midpoint of the headband; in addition, the philtrum line positioning rod is perpendicular to the head band.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to a head and face symmetry measuring device and system. Background technique [0002] In the clinical design, facial symmetry surgery includes microtia surgery, eye plastic surgery, rhinoplasty surgery, lip plastic surgery, orthognathic surgery, etc., all of which need to be evaluated and designed for the symmetry of the corresponding organs before surgery. The symmetry of the head and face directly affects the overall image of the individual, so the symmetry measurement of the preoperative design is particularly important, especially for microtia surgery. Since the ears are distributed on both sides of the skull, the symmetry of the ears is more symmetrical than that of the facial organs. Sex is harder to measure. [0003] In clinical practice, the common preoperative design of ear reconstruction is to 3D print the healthy ear. During the reconstruction of the affected ear, the cos...
