Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical instruments, in particular to the technical field of ear reconstruction positioning aids. Background Art
[0002] Congenital microtia is a genetic disease with an unknown cause. Its main clinical symptoms are poor development of the auricle, often accompanied by external auditory canal atresia, middle ear and maxillofacial deformities. According to statistics, 0.8 to 4.53 newborns per 10,000 newborns in the world suffer from congenital microtia. Although the prevalence of congenital microtia is not high, it has a serious impact on the facial beauty and mental health of children.
[0003] Congenital microtia requires auricular reconstruction surgery, which is to reconstruct an ear on the affected side that is the same size and symmetrical with the healthy ear. Currently, doctors hold a transparent film on the patient's normal ear and draw on it, then flip the transparent film over and position it on the deformed side. This method is prone to inaccurate positioning and may cause asymmetry in the reconstructed ear. Utility Model Content
[0004] The purpose of the utility model is to solve the problems in the prior art and to provide an ear reconstruction positioning aid that can solve the above problems.
[0005] To achieve the above-mentioned purpose, the utility model proposes an ear reconstruction positioning aid, including a head ring, a front positioning block is provided on the front side of the head ring, a rear positioning block is provided on the rear side of the head ring, the front positioning block and the rear positioning block are connected by a fixing frame, a mounting block is provided above the fixing frame, a positioning seat is installed on the mounting block, a spirit level is provided on the positioning seat, a mounting groove is horizontally penetrated on the positioning seat, a rotating shaft is rotatably installed in the mounting groove, threaded columns are symmetrically provided on both sides of the rotating shaft, a moving block is threadedly installed on the threaded column, a vertical positioning ruler is connected to the bottom of the moving block, a sliding groove is provided on the inner side of the positioning ruler, a horizontal positioning strip is slidably installed in the sliding groove, and scales are marked on the positioning ruler and the positioning strip.
[0006] Preferably, end covers are installed at both ends of the rotating shaft, and the end covers are provided with rotating handles.
[0007] Preferably, a slot is provided at the top of the mounting block, and an insert block is provided at the bottom of the positioning seat, and the slot and the insert block are installed in a matching manner.
[0008] Preferably, the insert block is a square slot.
[0009] Preferably, it further comprises a positioning frame, wherein a center block is provided at the top middle of the positioning frame, and a groove matching the center block is provided in front of the front positioning block.
[0010] The beneficial effects of the utility model are as follows: the utility model connects the positioning rulers on both sides through the rotating shaft. When the positioning ruler on one side is moved, the positioning ruler on the other side will also move synchronously, which can conveniently locate the ear and improve the accuracy of positioning; the setting of the level can ensure that the rotating shaft is in a horizontal position, thereby ensuring accurate positioning.
[0011] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS
