Problems solved by technology

[0002] The nasal prosthesis currently used is generally a one-piece nasal prosthesis. The doctor selects the corresponding nasal prosthesis according to the customer's nose shape, and then fits the nasal prosthesis to the side of the nose according to the characteristics of the customer's nose for carving so that it is in line with the nose. Matching, it is difficult for doctors with little experience to complete the carving better, and it is difficult for experienced doctors to do precise carving, resulting in poor fit between the nasal prosthesis and the nose, affecting postoperative recovery, and even causing Nasal prosthesis falls off

Embodiment 1

[0045] Choose laser equipment with power of 30W-60W, engraving speed of 100mm / s-500mm / s, point spacing of 0.08mm-0.15mm, and one layer cutting can reduce the thickness of 0.1mm-0.3mm.

[0046] Such as figure 1 As shown, the three-dimensional simulation display of nasal prosthesis 1 and nose 8, such as figure 2 As shown, the three-dimensional simulated nasal prosthesis overlaps with the nose, and the nasal prosthesis is divided into a layered part 5 that needs to be removed and a reserved part 6 that needs to be retained, as shown in image 3 As shown, the separate 3D simulation data of the delaminated part 5 and the reserved part 6.

[0047] Such as Figure 4 As shown, adjust the best laser focus distance of the equipment, set the corresponding energy parameters, and fix the nasal prosthesis 1 with a fixture. The silicone material is quite special, so it must be fixed with a fixture to prevent the nasal prosthesis from shaking, which will affect the carving work. Then imp...

Embodiment 2

[0055] Using the laser layer cutting and engraving method of Embodiment 1, the step S3 further includes: cleaning the residual substances on the surface of the nasal prosthesis with an air supply device after removing one processing layer. During the layer cutting process, dust and other impurities will be generated, and dust and other impurities will stick to the surface of the product. If it is not cleaned in time, the accuracy of layer cutting will be affected. After layer cutting, use the air supply equipment to blow and clean it once to remove dust, etc. The effect of impurities on layer cutting of laser equipment.

Embodiment 3

[0057] Using the laser layer cutting engraving method of Embodiment 1, when the laser equipment cuts the nasal prosthesis, the nasal prosthesis is placed in a nitrogen environment for layer cutting. The nasal prosthesis is placed in a nitrogen environment. During the layer cutting process, the surface temperature of the silicone prosthesis is changed through the particularity of nitrogen, and the silicone prosthesis product will not be burned due to long-term high temperature, which will affect the quality of the prosthesis itself. , and the nitrogen is relatively stable, which can prevent the characteristics of the nasal prosthesis from changing under high temperature.

Abstract

The invention discloses a method for laser engraving of a nasal prosthesis. The nasal prosthesis is fixed, the nasal prosthesis and a laser engraving range are within the same straight line range, nasal prosthesis model data are imported into a laser device, to-be-eliminated nasal prosthesis eliminating data in the model data are selected, and according to the eliminating data, the laser device emits lasers to carry out layer peeling on the nasal prosthesis until the nasal prosthesis forms a preset shape. By using the laser device to carry out the layer peeling on the nasal prosthesis, unneeded parts of the nasal prosthesis can be accurately eliminated, needed parts can be reserved, the processing accuracy of a laser beam is much higher than the processing accuracy of an operating knife, and the interference of human factors does not exist. If the model data and the eliminating data are accurate enough, the nasal prosthesis can be accurately eliminated, and the nasal prosthesis can be in accordance with the preset shape so that the reserved nasal prosthesis can be perfectly fitted on the nose. The fitting degree of the nasal prosthesis and the nose is greatly improved, and the post-operation risk is lowered. The method does not depend on the professional eliminating skill of doctors, the doctors with general operational ability can carry out implementation, and the implementation difficulty of the method is lowered.
