“…A prototipagem rápida permite, por exemplo, a produção de guias de broca específicos para a colocação de parafusos transpediculares cervicais, que apresentam grande eficiência, por reduzirem o tempo cirúrgico e aumentarem a precisão da implantação dos parafusos (Blake et al, 2019). Segundo Kamishina et al (2019), o uso destes guias resultou em desvios dos parafusos de menos de 1 milímetro, contribuindo para a diminuição de lesões iatrogênicas nas estruturas adjacentes.…”

“…No caso de animais mutilados, foi possível a fabricação de diversos protótipos para a reabilitação e melhora da qualidade de vida desses pacientes. Como, por exemplo, a produção de bicos para aves que sofreram acidentes, cascos para quelônios com extensas lesões nesta área, e próteses para animais que perderam um ou mais membros (Blake et al, 2019).…”

A prototipagem rápida é realizada em impressoras em três dimensões (3D), que utilizam vários materiais, como nylon, metal ou células de tecidos, viabilizando a produção de objetos de diversas formas e tamanhos. Para isto, ela trabalha a partir de uma imagem virtual do objeto desejado. Esta tecnologia traz diversas possibilidades na medicina veterinária, como a fabricação de modelos anatômicos fidedignos, placas, próteses e guias de broca customizados para o paciente, contribuindo para a capacitação de estudantes de graduação e residentes, além de aumentar a confiança do cirurgião, por possibilitar o planejamento e treinos prévios aos procedimentos, aumentando sua precisão cirúrgica e reduzindo o tempo do procedimento e o número de lesões iatrogênicas causadas em estruturas adjacentes à área de interesse. Além disso, os protótipos podem contribuir para a reabilitação de pacientes traumatizados ou mutilados, como aves, quelônios e outros animais silvestres. Mas seu custo relativamente alto, e a falta de profissionais capacitados para sua elaboração ainda limitam seu uso, porém a redução no tempo que propicia na execução de tratamentos pode compensar seu investimento.

“…Numerous criteria should be taken into consideration when selecting a printer including application type, accuracy, printing speed, technical requirements, ability to mix substrates or colors, size, cost, and materials. [14][15][16][17][18][19] Depending on the application, materials may be selected for their biomechanical or tactile properties, color, cost, sterilization method, and biocompatibility (Figure 2). Finally, postprinting processing is typically required to remove structures supporting overhanging surfaces of the 3D prints (FDM printers), powders, or resins (SLS, SLA, and IJ printers, Table 1, Figure 1).…”

“…Alternatively, CAD may be used to produce scaffolds, sculpt the models to remove or edit processing defects, or design replicas to recreate anatomical models 14 . The conversion of images into 3D computer prototypes has been reviewed elsewhere, 14–19 but briefly includes the following steps: (1) obtaining prototype components (eg, images) from live or cadaver models or CADs; (2) converting the original data into 3D surface models composed of “meshes,” typically consisting of a stereolithography file (.STL) or other types of files (eg, .OBJ, .3DM); (3) processing the model with software (Table S1) to reduce noise and artifacts; and (4) converting the model file into a file type recognized by the printer.…”

Applications of 3‐dimensional printing in small‐animal surgery: A review of current practices

2021

View full text Add to dashboard Cite

printing, also called rapid prototyping or additive manufacturing, transforms digital images into 3D printed objects, typically by layering consecutive thin films of material. This technology has become increasingly accessible to the public, prompting applications in veterinary surgery. Three-dimensional prints provide direct visualization of complex 3D structures and also haptic feedback relevant to surgery. The main objective of this review is to report current applications of 3D printing in small-animal surgery, including surgical education, preoperative planning, and treatment of tissue defects. The reported uses of 3D prints, their proposed advantages, and current limitations are discussed considering published evidence. Aspects of the manufacturing process specific to each application are described, along with current practices in veterinary surgery.

“…AM techniques are used to create physical prototypes as well as end-use parts. The application of 3D printing or AM in the field of veterinary medicine is increasing, especially to produce anatomical models that are used in education and preoperative planning (Blake et al , 2019; Freitas, 2011; Pijanka et al , 2019). There are also some examples of the use of AM for veterinary orthopedic surgery (Harrysson et al , 2015).…”

Purpose Chicken orthoses that cover the ankle joint area are not commercially available. Therefore, the main purpose of this study is to fabricate a customised temporary Ankle–Foot Orthosis (AFO) for a chicken with a twisted ankle using computer-aided design (CAD) and three-dimensional (3D) printing. The secondary objective of the paper is to present the specific application of Additive Manufacturing (AM) in veterinary medicine. Design/methodology/approach The design process was based on multiple sketches, photos and measurements that were provided by the owner of the animal. The 3D model of the orthosis was made with Autodesk Fusion 360, while the prototype was fabricated using fused deposition modelling (FDM). Evaluation of the AFO was performed using the finite element method. Findings The work resulted in a functional 3D printed AFO for chicken. It was found that the orthosis made with AM provides satisfactory stiffen and a good fit. It was concluded that AM is suitable for custom bird AFO fabrication and, in some respects, is superior to traditional manufacturing methods. It was also concluded that the presented procedure can be applied in other veterinary cases and to other animal species and other parts of their body. AM provides veterinary with a powerful tool for the production of well-fitted and durable orthoses for animals. Research limitations/implications The study does not include the chicken's opinion on the comfort or fit of the manufactured AFO due to communication issues. Evaluation of the final prototype was done by the researchers and the animal owner. Originality/value No evidence was found in the literature on the use of AM for chicken orthosis, so this study is the first to describe such an application of AM. In addition, the study demonstrates the value of AM in veterinary medicine, especially in the production of devices such as orthoses.
