Auricular frame locating device for auricle reconstruction surgery

Abstract

The invention discloses an auricular frame locating device for auricle reconstruction surgery, which comprises a head ring, a reference strip with the upper end connected with the middle of the front side of the head ring, two auricular locating strips with upper ends connected with the head ring and comparison measurement strips which are connected to the auricular locating strips in a one-to-one correspondence manner, wherein the two auricular locating strips are vertically arranged at the two sides of the reference strip, the head ring, and the auricular locating strips and the comparison measurement strips are all provided with length scale. When the auricular frame locating device is used, the head ring is worn at the head of a patient, the reference strip is superposed with a facial midline, the two auricular locating strips are adjusted to be symmetrical to the reference strip, one auricular locating strip is positioned at a normal aural region, the distance from the crus of helix of the normal aural region to the ajina, the distance from the antilobium to the outer canthus and the distance from the earlobe to the outer part of the nosewing are measured through the comparison measurement strips, and an auricular frame is located through the comparison measurement strips at a surgical side and the three distances; and moreover, a comparison measuring scale can be also used to measure the auricle height, thus, the auricular frame is enabled to be consistent to the forward turning angle of the normal ear and symmetrical to the normal ear.

Description

technical field [0001] The invention relates to the field of medical devices, in particular to an auxiliary device for placing an ear support symmetrically with the normal ear on the other side during auricle reconstruction surgery. Background technique [0002] Auricle reconstruction surgery is suitable for external ear defects, congenital small ears or no ears caused by congenital or traumatic factors. Auricle reconstruction surgery is generally carried out in three stages: the first stage, the expander is buried in the mastoid area; the second stage , taking costal cartilage sculptures or using artificial ear stents to bury in the position of the dilator, and waiting to grow around the ear; the third stage is to trim the earlobe and residual ear tissue. [0003] It can be seen from the above process that auricle reconstruction surgery is a difficult plastic surgery. A realistic auricle needs to be the same as or close to a normal ear. The main factor affecting the surgica...

Problems solved by technology

[0006] In view of this, the present invention provides an ear support positioning device for auricle reconstruction surgery. The device can be positioned on the head, and the position of the ear support can be determined by comparing and measuring the position of the normal ear. The technical problem of unsatisfactory postoperative effect caused by positioning the ear bracket based on the doctor's naked eye observation and subjective judgment
