Preoperative designer for nose augmentation surgery

Abstract

The invention belongs to the technical field of surgical apparatuses, and in particular relates to a preoperative designer for a nose augmentation surgery. The preoperative designer comprises a transverse beam, vertical beams, longitudinal beams and short rulers, wherein a transverse sliding groove is formed in the side face of the transverse beam; a first vertical sliding groove is formed in one side of each vertical beam; the side, back away from the first vertical sliding groove, of each vertical beam is provided with a second vertical sliding groove; convex sliding blocks are arranged in the first vertical sliding grooves; the convex sliding blocks are matched with the transverse sliding groove; a boss is arranged at one end of each longitudinal beam; the bosses are matched with the second vertical sliding grooves; a longitudinal beam slideway is arranged in each longitudinal beam in a length direction; a short ruler slideway is arranged in each short ruler in a length direction; each longitudinal beam slideway and each short ruler slideway are connected by virtue of an adjusting bolt; and scales are arranged on the transverse beam, the vertical beams, the longitudinal beams and the short rulers. The preoperative designer disclosed by the invention is simple in structure, convenient to use, accurate in center location, precise in measurement, high in making precision, high in design efficiency and low in error, and the preoperative designer is capable of measuring the widths and the heights of various cross sections of a nose, so as to better conduct the nose augmentation surgery.

Description

technical field [0001] The invention belongs to the technical field of surgical instruments, and in particular relates to a preoperative designer for rhinoplasty. Background technique [0002] Rhinoplasty is a common surgical plastic surgery, mainly in two ways: injection rhinoplasty and prosthesis rhinoplasty. For prosthetic rhinoplasty, it is necessary to incise the nasal columella or the inner edge of the nasal alar and stick the nasal bone to peel off the cavity where the prosthesis is placed. According to modern aesthetic standards, the upper boundary of the cavity should be located in the middle and lower 1 / 3 of the line between the brow center and the center of the eye corner. For rhinoplasty by injection, comprehensive design and precise measurement of the nose shape are required before rhinoplasty. It is very inconvenient to measure the nose shape with a ruler, set square and protractor, and the measurement results are not accurate. Using a three-dimensional Laser...

Problems solved by technology

For rhinoplasty by injection, comprehensive design and precise measurement of the nose shape are required before rhinoplasty. It is very inconvenient to measure the nose shape with a ruler, set square and protractor, and the measurement results are not accurate. Using a three-dimensional Laser scanning equipment can solve this problem, but the cost of 3D laser scanning equipment is too high

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