[004] A laparoscopia consiste em que o médico faça uma pequena incisão na região a ser examinada ou tratada, por onde introduz o laparoscópio (aparelho por meio do qual irá visualizar e tratar a região abordada), que consiste em um fino tubo de fibras óticas, através do qual pode visualizar os órgãos internos e fazer intervenções diagnósticas ou terapêuticas.  Laparoscopy is where the doctor makes a small incision in the region to be examined or treated, through which he introduces the laparoscope (apparatus through which he will view and treat the area covered), which consists of a thin tube of fibers. through which you can visualize the internal organs and make diagnostic or therapeutic interventions.
[005] Outras pequenas incisões podem ser necessárias para introduzir os instrumentos cirúrgicos usados na videolaparoscopia. [005] Other small incisions may be necessary to introduce the surgical instruments used in videolaparoscopy.
[006] Esta técnica tem a vantagem de ser minimamente invasiva e ocasionar, assim, um menor trauma cirúrgico, menos sangramento intra-operatório, menor dor pós- operatória, recuperação pós-cirúrgica mais rápida e retorno mais cedo às atividades habituais e ao trabalho, além de menores cicatrizes.  [006] This technique has the advantage of being minimally invasive and thus result in less surgical trauma, less intraoperative bleeding, less postoperative pain, faster postoperative recovery and earlier return to usual activities and work. , besides smaller scars.
[007] Mais especificamente numa cirurgia laparoscópica faz-se o pneumoperitoneo para visualização dos órgãos. O procedimento do pneumoperitoneo consiste em aplicar uma agulha por uma incisão no abdómen, conectar a referida agulha a um insufiador que injeta o gás necessário para a expansão da cavidade.  More specifically in laparoscopic surgery pneumoperitoneum is made for visualization of the organs. The pneumoperitoneum procedure consists of applying a needle through an incision in the abdomen, connecting said needle to a deliever who injects the gas necessary for the expansion of the cavity.
[008] Após a obtenção do pneumoperitoneo posiciona-se o trocater dentro da cavidade, ficando ele justaposto às paredes da incisão impedindo a saída do gás.  [008] After obtaining the pneumoperitoneum, the trocar is positioned within the cavity, being juxtaposed to the walls of the incision preventing the outflow of the gas.
[009] Quando é necessária a ampliação da incisão cirúrgica, pode ocorrer a saída do gás de expansão, sendo que nesses casos o cirurgião é obrigado a evitar a saída dos gases, por quaisquer meios.  When enlargement of the surgical incision is required, the expansion gas may escape, in which case the surgeon is obliged to prevent the escape of the gases by any means.
[010] É conhecido do estado da técnica um dispositivo de vedação mecânica especificamente desenvolvido para evitar a saída do gás de expansão nesses casos.  [010] A mechanical sealing device specifically designed to prevent outflow of expansion gas in such cases is known in the art.
[011] Dito equipamento de vedação é revelado no documento BR 10 2014 017181 9 A2, intitulado de "BALÃO ANELAR INFLÁVEL PARA CIRURGIAS LAPAROSCÓPICAS"; o qual versa sobre um balão anelar que tem a forma de um toróide expansível, o qual envolve o perímetro do trocater, entendido como um tubo para inserção de gás na cavidade abdominal pneumoperitonea, dito balão anelar possui uma entrada e saída de ar que pode ser vedada por válvula ou mesmo, por obstrução mecânica de pinças. O balão anelar se infla junto à incisão cirúrgica ampliada, mas, envolvendo o trocater, de forma a vedar a saída do gás de expansão. [011] Said sealing equipment is disclosed in document BR 10 2014 017181 9 A2 entitled "INFLATABLE RING BALLOON FOR LAPAROSCOPIC SURGERIES"; which is about an annular balloon that has the form of an expandable torus, which surrounds the perimeter of the trocar, understood as a tube for insertion of gas into the pneumoperitoneal abdominal cavity, said annular balloon has an air inlet and outlet that can be sealed by valve or even by mechanical obstruction of forceps. The annular balloon inflates near the enlarged surgical incision, but, surrounding the trocar, to seal out the expansion gas.
Pontos deficientes do estado da técnica  Poor points of the prior art
[012] Apesar de trazer grandes vantagens nas cirurgias de lapa rosco pi as, o grande inconveniente desse balão anelar inflável está em seu elevado custo.  [012] Although it has great advantages in lapa rosco pias surgeries, the major drawback of this inflatable ring balloon is its high cost.
[013] Esse substanciai custo se deve ao seu projeto, que por ser um dispositivo inflável requer um processo primoroso de fabricação com várias etapas que utiliza equipamentos de grande precisão.  [013] This substantial cost is due to its design, which as an inflatable device requires an exquisite multi-step manufacturing process that utilizes high precision equipment.
Sumário da disposição  Layout Summary
[014] Pensando em disponibilizar ao setor hospitalar um dispositivo, de custo acessível, para evitar a saída de gás do pneumoperitoneo em procedimentos cirúrgicos de laparoscopia, o inventor com notório conhecimento setorial, criou e desenvolveu o objeto da presente patente, "DISPOSIÇÃO INTRODUZIDA EM VEDADOR CÓNICO PARA LAPAROSCOPIA", revela um vedador cirúrgico, que envolto na haste tubular do trocater e inserido no corte cirúrgico, faz a vedação deste corte cirúrgico, para que o gás injetado na cavidade abdominal do paciente não seja ejetado para o meio ambiente e comprometa a expansão necessária da cavidade abdominal, necessária a procedimentos cirúrgicos específicos.  [014] Thinking of providing the hospital sector with an affordable device to prevent pneumoperitoneum gas leakage in laparoscopic surgical procedures, the inventor with well-known industry knowledge has created and developed the subject-matter of this patent, "PROVISION INTRODUCED IN LAPAROSCOPY CONICAL SEAL ", reveals a surgical seal, which is wrapped around the trocar tubular stem and inserted into the surgical cut, seals this surgical cut so that the gas injected into the patient's abdominal cavity is not ejected into the environment and compromises the necessary expansion of the abdominal cavity, necessary for specific surgical procedures.
[015] A utilização do vedador cónico para laparoscopia é bastante simplificada e evita a perda do pneumoperítoneo em casos de ampliação da incisão abdominal. [015] The use of the laparoscopic conical seal is greatly simplified and avoids the loss of pneumoperitoneum in cases of enlargement of the abdominal incision.
[016] Envolvendo o trocater com o vedador cónico para laparoscopia e posicionando-o junto ao orifício interno ou na espessura da parede se evitará o vazamento do gás, permitindo assim o prosseguimento da cirurgia sem maiores dificuldades.  [016] Wrapping the trocar with the laparoscopic conical seal and placing it close to the inner hole or wall thickness will prevent gas leakage, thus allowing further surgery without further difficulties.
[017] O vedador cirúrgico, em apresentação, se comparado ao dispositivo do estado da técnica (baião anelar) apresenta diversas melhorias funcionais e grandes vantagens, principalmente, no que tange ao processo de produção.  [017] The surgical seal, in presentation, compared to the state-of-the-art device (annular balloon) has several functional improvements and great advantages, especially regarding the production process.
[018] Totalmente desenvolvido em polímero cirúrgico (silicone), o objeto do presente pedido, vedador cónico para laparoscopia, possui formato cónico que permite adentrar os tecidos (pele, camadas musculares e de gordura) do paciente até encontrar seu limite físico, estancando assim o orifício que foi efetuado para realizar a cirurgia.  Fully developed in surgical polymer (silicone), the object of this application, conical sealer for laparoscopy, has a conical shape that allows the patient to enter the tissues (skin, muscle and fat layers) until they find their physical limit, thus stopping. the hole that was made to perform the surgery.
[019] No centro da peça, um orifício do diâmetro do trocáter, tem a função de permitir a passagem do mesmo sem que possibilite a passagem do gás durante o processo cirúrgico.  [019] In the center of the piece, a hole of the diameter of the trocar has the function of allowing its passage without allowing the passage of gas during the surgical procedure.
[020] Para melhorar a eficácia da vedação, aletas flexíveis incorporadas ao vedador e também acompanhando o formato cónico, circundam toda sua superfície, impedindo a passagem de gases, uma vez que os tecidos orgânicos não possuem regularidade dimensional, de rigidez e textura.  [020] To improve sealing efficiency, flexible fins incorporated into the seal and also accompanying the conical shape, surround the entire surface, preventing the passage of gases, since organic fabrics do not have dimensional regularity, rigidity and texture.
[021] Quatro nervuras que percorrem ao longo do corpo do vedador, permitem que a estrutura das aletas se mantenha firme, sofrendo o mínimo de deformação, que é o necessário para se adaptar às camadas de tecido do paciente e promovendo a vedação correta. [021] Four ribs running along the seal body allow the fin structure to remain firm, with minimal deformation that is necessary to adapt to the patient's tissue layers and promoting correct sealing.
[022] Diferente do dispositivo do estado da técnica (baião anelar), o vedador cirúrgico, ora em apresentação, não precisa ser inflado dentro do orifício do paciente, o que facilita sua operação.  Unlike the state-of-the-art device (annular balloon), the surgical seal, now being presented, need not be inflated into the patient's orifice, which facilitates its operation.
[023] O objeto do estado da técnica (balão anelar) precisa de diversas etapas no seu processo de produção o que aumenta o tempo de produção, tais como injeção, solda por uitrassom e, além disso, precisa de um cuidado grande para evitar rebarbas, que podem prejudicar o processo de vedação do gás durante a cirurgia.  [023] The state-of-the-art object (ring balloon) needs several steps in its production process which increases production time such as injection, ultrasound welding and also needs great care to avoid burrs , which can impair the gas sealing process during surgery.
[024] O vedador cirúrgico cónico pode ser produzido em apenas um processo de injeção, que garante precisão dimensional, escaiabiiidade e o mínimo de perdas.  [024] The tapered surgical seal can be produced in just one injection process, which ensures dimensional accuracy, scalability and minimal loss.
[025] É de se compreender assim que o dispositivo vedador cirúrgico cónico em questão é extremamente simples em sua construtividade, sendo, portanto, de fácil exequibilidade, porém, com excelentes resultados práticos e funcionais.  [025] It is thus to be understood that the conical surgical sealing device in question is extremely simple in its constructivity and is therefore easily practicable, but with excellent practical and functional results.
[026] Idealizado com desenho inovador, resulta em um conjunto harmónico, de aspecto bastante peculiar e, sobretudo característico, sendo que, além do aspecto construtivo, o produto destacasse pela sua versatilidade e comodidade de utilização. [026] Conceived with innovative design results in a harmonious assembly, peculiar and characteristic aspect above, wherein, besides the constructive aspect, the product s stands out for its versatility and ease of use.
