Rhinoplasty Surgery Designer

Abstract

The invention discloses a nasal-bridge augmentation designer which comprises an arc guide rail which is matched with a forehead, a fixing strip which is vertical to the guide rail and is connected with the middle point of the guide rail, and two sliders which are vertical to the guide rail and are matched with the guide rail in a sliding manner, wherein the guide rail, the fixing strip and the sliders are all provided with length scale. When the nasal-bridge augmentation designer is used, the arc guide rail is tightly attached to the forehead and is fixed, the fixing strip is superposed with a facial midline, the left and right boundaries of a dissection lacune are quantitatively determined through the sliders, meanwhile, a position which is one third of the distance from the ajina to the canthus center is determined to be the upper boundary of the lacune through the length scale on the fixing strip, and modification can be carried out at any time until satisfaction. The fixing strip and the sliders are taken as reference when a line is drawn, and the nasal-bridge augmentation designer has high line drawing precision and quick speed, so the design efficiency can be effectively improved, the design error is reduced, and the surgery effect is ensured.

Description

technical field [0001] The invention relates to the field of medical instruments, in particular to a device for preoperative design, line drawing and measurement of rhinoplasty. Background technique [0002] Rhinoplasty is a common surgical plastic surgery. There are mainly two methods: injection rhinoplasty and prosthesis rhinoplasty. For prosthesis rhinoplasty, it is necessary to incise the nasal columella or the inner edge of the nasal alar and then paste the nasal bone to peel off the place where the prosthesis is placed. For the cavity, the left and right boundaries and the upper boundary of the dissection cavity need to be designed before surgery. In order to make the postoperative effect conform to modern aesthetic standards, the upper boundary of the cavity must be located in the middle and lower 1 / 3 of the line between the center of the brow and the center of the corner of the eye. . [0003] At present, doctors rely entirely on observation and experience to determ...

Problems solved by technology

[0003] At present, doctors rely entirely on observation and experience to determine the boundaries of the dissection cavity during preoperative design, which causes large errors in line drawing and affects postoperative results. In addition, drawing lines entirely by hand is slow. It is also difficult to guarantee the accuracy of line drawing. In addition, once the line is drawn, it is very troublesome to modify it.
