- ItemModelo de treinamento em técnicas microcirúrgicas da Unifesp(Universidade Federal de São Paulo (UNIFESP), 2020-11-27) Feitosa, Roney Goncalves Fechine [UNIFESP]; Garcia, Elvio Bueno [UNIFESP]; Universidade Federal de São PauloIntroduction: Microsurgery is a fundamental technique in reconstructive plastic surgery for complex treatments involving free tissue transfer. Their training involves years, and the financial and ethical costs should not be neglected. The training model is an important tool in the training of surgical techniques, in addition to having an important social impact, as the professional will perfect the techniques and improve the intervention in the human being. Objective: To develop a non-animal, portable, low cost and effective microsurgery training model. Method: A device for training microsurgical techniques was devised. The device has been classified by the International Patent Classification. Bibliographic research was carried out using the Health Sciences Descriptors (DeCS): Microsurgery, Simulation Training, Device, Suture Techniques and Surgical Anastomosis. The search for anteriority was done using patent banks. Design Thinking was used to develop prototypes to validate the concepts and functionality of the device. Results: Thirteen devices with similarities to the device under study were found in patent banks. None of these devices showed great similarities with the device under study, to the point of making the grant of the patent unfeasible. Conclusion: A synthetic, non-animal training device was developed in microsurgical techniques.
- ItemDispositivo de aquecimento estéril reutilizável para óticas cirúrgicas e líquidos no transoperatório(Universidade Federal de São Paulo (UNIFESP), 2020-11-27) Silva, Cassius Martins E [UNIFESP]; Garcia, Elvio Bueno [UNIFESP]; Universidade Federal de São PauloIntroduction: With the confirmation of the use of minimally invasive surgery, using videolaparoscopy and robotic surgery, the use of surgical optics is increasingly widespread and frequent. One of the difficulties experienced by the doctor during the minimally invasive surgical procedure is the reduction of visual capacity, due to the fogging of the front glass of the optics. The condensation of water vapor on the lens when entering the heated environment of the abdominal cavity or any body cavity, occurs due to the temperature difference between the intracavitary water vapor and the optic's distal glass. The fogging of the optics forces the surgeon to remove the optical accessory from the surgical environment, to perform its cleaning, which cools the glass, which causes it to fog up again, when the optics return to the cavity. This increases the surgical time, the number and the variety of postoperative complications. To avoid this process, we promote the heating of the distal end of the optic. However, surgical devices that currently exist do not do so with the required efficiency and speed, therefore the need for a more functional solution. Objective: To develop a functional device for heating the distal end of surgical optics during the procedure. Method: The development of the device idea was carried out using the Design Thinking Method. For the realization of the device, simple materials were used, which have already been studied comprehensively by other authors, and used of their physical-chemical properties for a better development of the artifact in question. The materials are: Polyester, Polyurethane, Sodium Acetate (C2H3NaO2), Stainless Steel (surgical) and aluminum. Results: A cylindrical device with a flat base was designed, with a hole in the center of the upper portion that leads to a 250 mL reservoir, wrapped in another 350 mL reservoir. This reservoir is filled with Sodium Acetate (C2H3NaO2) and contains a surgical steel disc, which when bent, fires a trigger that forms a chain reaction determining the precipitation of Sodium Acetate and its crystallization. This causes an exothermic reaction, which releases heat and heats the liquid contained in the 250 mL reservoir of the device, which in turn will be used for heating and cleaning the optical end, preventing the condensation of water vapor from occurring. Conclusion: A device for heating the distal end of liquids and surgical optics that is sterile and reusable was developed.
- ItemMétodo de identificação por Ressonância Magnética Nuclear (RMN) e quimiometria de biomarcadores para doenças mentais graves e usos do mesmo(2021-08-31) Hayashi, Mirian Akemi Furuie [UNIFESP]; Tasic, Ljubica; Poppi, Ronei Jesus; Brietzke, Elisa; http://lattes.cnpq.br/5559309395232147; UnicampA presente invenção se refere a um método de identificação por ressonância magnética nuclear (RMN) e quimiometria de biomarcadores para doenças mentais graves, como transtorno bipolar e esquizofrenia que por meio do perfil metabólico de indivíduos com SCZ e TB com controles saudáveis (grupo controle), aplica ferramentas de ressonância magnética nuclear (RMN) e de quimiometria.
- ItemModelo de grampeador cirúrgico para onfaloplastia em abdominoplastia(Universidade Federal de São Paulo (UNIFESP), 2019-10-18) Sanjuan, Victor Rodamilans [UNIFESP]; Gomes, Heitor Francisco De Carvalho [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: The omphaloplasty is a long and laborious surgical stage in abdominoplasty and currently there is no surgical stapler that facilitates this procedure. Objective: To develop a surgical stapler for omphaloplasty model. Method: The Canvas Patent model was used for the development of this surgical instrument. A literature review and patent search related to the subject were performed. A questionnaire was sent to all SBCP members by email to determine the technical preferences of the omphaloplasty. A description has been made that contains features and functions of the surgical stapler, associated with drawings, figures and a prototype to identify and illustrate each part of the product. Results: 575 plastic surgeons answered the questionnaire. A three-piece stapling system has been developed which, after correct alignment, is capable of firing eight surgical staples simultaneously, in order to attach the navel skin to the abdominal flap. Related patents in the search for priority were described and compared with the study model, highlighting their advantages and disadvantages. The developed model provides expectation to facilitate omphaloplasty, reduce surgical time and standardize results. This stapling system was not found in the literature searched. Conclusion: A surgical stapler for omphaloplasty model was developed and submitted for patent registration
- ItemEasy-implanter: dispositivo para colocação das unidades foliculares(Universidade Federal de São Paulo (UNIFESP), 2019-12-13) Buttros, Juliana Beatriz [UNIFESP]; Ferreira, Lydia Masako [UNIFESP]; Universidade Federal de São Paulo (UNIFESP)Introduction: Alopecia affects many individuals worldwide and hair transplant is the only ultimate treatment. Hair transplantation surgery has dramatically improved over the past decade thanks to the emergence of new techniques of follicular unit transplantation and follicular unit excision (FUE). The popularity of FUE hair transplantation has provoked the development of more advanced devices that potentially increase the quality of the hair transplant procedure, but new implanters need to be developed to minimize injury to these delicate grafts and cost while also increasing the speed of the procedure. Objective: To develop a manual device for transplanting FUE follicular units. Methods: A novelty search was conducted in national (INPI/BR) and international (USPTO, WIPO, EPO and Google Patent Search) databases. The Design Thinking methodology, which is divided into four phases (Discover, Define, Develop, and Deliver), was used in this project. In the Discover phase, interviews and desk research were conducted; in the Define phase, the main parameters and the purpose of the device were determined; in the Develop phase, brainstorming sessions were carried out; and, in the Deliver phase, the industrial design was created. Results: The characteristics of the device were defined. The final model features all the functionality defined through Design Thinking and resulted in a manual transplanter for three follicular units with individual shot and easy sterilization. Conclusion: The Easy-Implanter, a manual device for transplanting multi follicular units, was developed.
