Description

Auxiliary shaping instrument for open eye angle

Technical Field

The utility model relates to the field of medical auxiliary instruments, in particular to an auxiliary shaping instrument for an open eye angle.

Background

The inner and outer canthus forming technique is commonly known as canthus opening. The method is to correct and amplify the inner and outer canthus respectively by an operation mode so as to remove the inner canthus skin and prolong the horizontal length of the eye fissure, thereby achieving the effect of amplifying eyes. The Mustarde method is one of the commonly used open-eye angle surgical methods, and is also called four-flap-forming surgical procedure, in which four flaps are formed, and after the positions of the flaps are interchanged, the inner canthus skin tag can be improved.

Since a plurality of incisions are required to be made in the Mustarde method, marking lines are required to be drawn in advance before operation in order to ensure the accuracy of the incisions. Preoperative line drawing step of Mustarde method: (1) When the patient is in plane view, the center of the pupil is at a point p which is the midpoint of the connecting line between the center of the pupil and the central line of the nose bridge, and the point is the position of a newly designed inner canthus point; (2) Pulling the inner canthus skin to the nose side until the skin tag disappears, wherein the original inner canthus point is the p' point; (3) Connecting the point p and the point p ', wherein the point o in the connecting line is inclined upwards and downwards to form inclined straight lines oa and ob with angles of 60 degrees respectively, the length of the inclined straight lines oa and ob is shorter than 2mm of the connecting line between the point p and the point p', and the straight lines ac and bd with angles of 45 degrees respectively form the point a and the point b to the nose bridge are the same as the lengths of the straight lines oa and ob; (4) From the actual medial canthus point p', a straight line of length equal to ab and ac is made parallel to each of the upper and lower eyelid rims. During operation, the operator cuts the skin along the mark line and deeply reaches the orbicularis oculi muscle, separates the orbicularis oculi muscle under two pairs of rectangular skin flaps, exposes the inner canthus ligament, then performs blunt separation at the point p, pushes away soft tissues, exposes the periosteum, and then pulls the inner canthus ligament at the point p' to the point p for suturing and fixing the ligament on the periosteum, so that the inner canthus interval is shortened.

In the preoperative setting-out, because the length that can relate to the marking line and the angle between the adjacent marking line, the setting-out degree of difficulty of using current tradition setting-out instrument (ruler, protractor etc.) is great, and has the setting-out instrument to be difficult for placing and influence the use to cause the condition that the setting-out exists the deviation.
