Description

DISPOSIÇÃO CONSTRUTIVA APLICADA EM DISPOSITIVO DE CONTROLE DE FIBRA ÓTICA CAMPO TÉCNICO CONSTRUCTION PROVISION APPLIED IN FIBER OPTIC CONTROL DEVICE TECHNICAL FIELD
[001 ] O seguinte relatório descritivo para modelo de utilidade se refere ao desenvolvimento de um dispositivo de controle da fibra ótica, combinado ao sistema de proteção anticontaminação em pregado no tratamento de endolaser para varizes, para tracionamento de fibra ótica em técnica de ablação térmica. ANTECEDENTES DA INVENÇÃO [001 ] The following descriptive report for a utility model refers to the development of an optical fiber control device, combined with the anti-contamination protection system used in the endolaser treatment for varicose veins, for optical fiber traction in the thermal ablation technique. BACKGROUND OF THE INVENTION
[002] O tratamento da insuficiência venosa dos membros inferiores evoluiu muito nos últimos anos, passando de técnicas clássicas, como a safenectomia cirúrgica, flebectomias1 (BABCOCK, 1907) e ligadura de perfurantes, para técnicas endovasculares ablativas com nítida tendência à desospitalização, ou seja, progrediu-se para procedimentos realizados preferencialmente em ambiente ambulatorial2 (BABCOCK, 1907; SHORTELI; MARKOVIC; DURHAM, 2009)1·2. [002] The treatment of venous insufficiency of the lower limbs has evolved a lot in recent years, moving from classic techniques, such as surgical saphenectomy, phlebectomies 1 (BABCOCK, 1907) and perforator ligation, to ablative endovascular techniques with a clear tendency to dehospitalization, or that is, progress was made to procedures performed preferably in an outpatient setting2 (BABCOCK, 1907; SHORTELI; MARKOVIC; DURHAM, 2009) 1 · 2 .
[003] A Ablação Térmica com Laser Endovenoso (EndoVenous[003] Endovenous Laser Thermal Ablation (EndoVenous
Laser Therapy - EVLT) representa uma das técnicas que mais se consagrou nas últimas décadas para o tratamento da doença venosa. Após o primeiro caso descrito, em 1998, por Boné3· 4 (1999), diversos aprimoramentos e otimizações foram realizados, evoluindo até as novas indicações presentes neste capítulo. Apesar de o EVLT configurar-se como técnica de escolha para tratamento das veias tronculares do sistema venoso superficial, tanto pela Society for Vascular Surgery (EUA)5 (GLOVICZKI et al., 2011) quanto pela European Society for Vascular Surgery (ESVS)6 (WITTENS et al., 2015), essas mesmas entidades recomendam a flebectomia ambulatorial para tratamento de tributárias varicosas7 (BONÉ, 1999; GLOVICZKI et al., 2011; MULLER, 1966; NAVARRO; MIN; BONÉ, 2001; WITTENS et al., 2015)3·4'5·6'7. Laser Therapy - EVLT) represents one of the most popular techniques in recent decades for the treatment of venous disease. After the first case described, in 1998, by Boné 3 · 4 (1999), several improvements and optimizations were carried out, evolving to the new indications present in this chapter. Although the EVLT is configured as the technique of choice for the treatment of trunk veins of the superficial venous system, both by the Society for Vascular Surgery (USA)5 (GLOVICZKI et al., 2011) and by the European Society for Vascular Surgery (ESVS)6 (WITTENS et al., 2015), these same entities recommend outpatient phlebectomy for the treatment of varicose tributaries 7 (BONÉ, 1999; GLOVICZKI et al., 2011; MULLER, 1966; NAVARRO; MIN; BONÉ, 2001; WITTENS et al., 2015) 3 · 4 ' 5 · 6 ' 7 .
[004] No contexto brasileiro, sabemos que a rotina da maioria dos serviços é a realização de múltiplas flebectomias em ambiente hospitalar, normalmente sob raquianestesia ou anestesia geral. A opção de escolha, que seria a flebectomia ambulatorial7 (MULLER, 1966), é notadamente subutilizada, além de trazer consigo desvantagens e limitações em casos extensos, com os quais nos deparamos frequentemente nos consultórios e ambulatórios da América Latina. Com essa análise, ao considerar a tendência termoablativa para troncos safênicos, surgiu a ideia da técnica de Ablação Térmica Total Assistida (ATTA), procedimento factível em ambiente ambulatorial. Lança-se mão do endolaser para veias possíveis de serem puncionadas, tratando tributárias (insuficientes ou inestéticas) de todos os calibres, com enfoque minimamente invasivo (MULLER, 1966)7. [004] In the Brazilian context, we know that the routine of most services is to perform multiple phlebectomies in a hospital environment, usually under spinal anesthesia or general anesthesia. The option of choice, which would be outpatient phlebectomy7 (MULLER, 1966), is notably underused, in addition to bringing with it disadvantages and limitations in extensive cases, which we often encounter in clinics and outpatient clinics in Latin America. With this analysis, when considering the thermoablative trend for saphenic trunks, the idea of the Assisted Total Thermal Ablation (ATTA) technique emerged, a feasible procedure in an outpatient setting. The endolaser is used for veins that can be punctured, treating tributaries (insufficient or unsightly) of all sizes, with a minimally invasive approach (MULLER, 1966) 7 .
[005] As vantagens das técnicas termoablativas são: período menor de convalescência, menor agressividade aos tecidos perivenosos8 (LIU et al., 2011), resolutividade e durabilidade adequadas9 (WOZNIAK; MLOSEK; CIOSTEK, 2016), maior conforto e comodidade no procedimento ambulatorial10· 11 (DO; KELLEY, 2007; YILMAZ et al., 2013), menor risco de sangramento e infecção e possibilidade de realização do procedimento sem a presença do profissional anestesiologista (YILMAZ et al., 2013) 8· 9· 10· 11. PROBLEMA DA TÉCNICA [005] The advantages of thermoablative techniques are: shorter period of convalescence, less aggressiveness to perivenous tissues8 (LIU et al., 2011), adequate resolution and durability 9 (WOZNIAK; MLOSEK; CIOSTEK, 2016), greater comfort and convenience in the procedure 10 · 11 (DO; KELLEY, 2007; YILMAZ et al., 2013), lower risk of bleeding and infection and possibility of performing the procedure without the presence of an anesthesiologist (YILMAZ et al., 2013) 8 · 9 · 10 · 11 . TECHNIQUE PROBLEM
[006] Etapa primordial do procedimento, a termoablação, em si gera receios quanto à energia a ser utilizada devido ao temido risco de complicações, como lesões térmicas de pele e outras estruturas perivenosas9· 32 (SHAHID et al., 2015; WOZNIAK; MLOSEK; CIOSTEK, 2016). Temos que levar em consideração todas as variáveis envolvidas: comprimento de onda do laser a ser usado, modo de entrega da energia, velocidade de tração e tipo de fibra, energia por centímetro linear de veia (LEED), além da potência nominal. [006] The primary step of the procedure, thermoablation, in itself generates fears about the energy to be used due to the feared risk of complications, such as thermal lesions of the skin and other perivenous structures 9 · 32 (SHAHID et al., 2015; WOZNIAK; MLOSEK; CIOSTEK, 2016). We have to take into account all the variables involved: wavelength of the laser to be used, mode of energy delivery, pull speed and fiber type, energy per linear centimeter of vein (LEED), in addition to rated power.
[007] O Laser Diodo de 1470 nm é atualmente reconhecido por reunir as maiores vantagens na termoablação endovenosa, com trabalhos demonstrando melhor perfil de entrega de energia em relação a outros comprimentos de onda 33· 34· 35· 36 (AKTAS et al., 2015; ARSLAN et al., 2017; DOGANCI; DEMIRKILIC, 2010; HIROKAWA et al., 2015). Com essas evidências em mãos, somadas à revisão bibliográfica que mostra resultados insatisfatórios em trabalhos que utilizaram comprimentos de onda de 980 e 810 nm14· 18 (PARK et al., 2007; WANG et al., 2018), optamos, na técnica ATTA, pelo comprimento de onda de 1470 nm. [007] The 1470 nm Diode Laser is currently recognized for bringing together the greatest advantages in endovenous thermoablation, with works demonstrating a better energy delivery profile in relation to other wavelengths 33 · 34 · 35 · 36 (AKTAS et al., 2015; ARSLAN et al., 2017; DOGANCI; DEMIRKILIC, 2010; HIROKAWA et al., 2015). With this evidence in hand, added to the literature review that shows unsatisfactory results in studies that used wavelengths of 980 and 810 nm 14 · 18 (PARK et al., 2007; WANG et al., 2018), we opted for the ATTA technique , at a wavelength of 1470 nm.
[008] Os geradores de laser podem entregar a energia luminosa em modo contínuo ou pulsado37 (BOS et al., 2008). A quantificação da energia total por segmento de veia tratada ou de superfície é mais prática de ser feita quando utilizamos o modo contínuo. Portanto, para a técnica ATTA, esse é o modo de escolha. [008] Laser generators can deliver light energy in continuous or pulsed mode 37 (BOS et al., 2008). Quantifying the total energy per treated or surface vein segment is more practical when using the continuous mode. So for the ATTA technique, this is the mode of choice.
[009] Para o tratamento dos troncos venosos principais, é ampla a discussão sobre o melhor modo de calcularmos a energia ideal para a efetiva termoablação. Contudo a maneira mais difundida em nosso meio, proposta desde 2005, é o cálculo energético por centímetro linear de veia (Linear Endovenous Energy Density- LEED)38· 39 40 (IGNATIEVAet al.,[009] For the treatment of main venous trunks, there is a wide discussion about the best way to calculate the ideal energy for effective thermoablation. However, the most widespread method in our country, proposed since 2005, is the calculation of energy per linear centimeter of vein (Linear Endovenous Energy Density- LEED) 38 · 39 40 (IGNATIEVA et al.,
2017; FOKIN et al., 2017; PROEBSTLE TM. et al., 2005). A fórmula utilizada é a seguinte: 2017; FOKIN et al., 2017; PROEBSTLE TM. et al., 2005). The formula used is as follows:
[010] LEED = E (energia total) / cm linear de veia E = P (potência) x T (tempo) [010] LEED = E (total energy) / linear cm of vein E = P (power) x T (time)
[011] Assim: LEED = P x T / centímetro linear de veia.[011] Thus: LEED = P x T / linear centimeter of vein.
SOLUÇÃO PROPOSTA [012] Uma solução para isto foi a criação de um dispositivo de tração mecânica da fibra, que a recua em 1 milímetro a cada clique de um botão rotacional (ATTA Control), objeto do pedido de patente BR 102020018402-4. PROPOSED SOLUTION [012] A solution for this was the creation of a mechanical fiber traction device, which retracts it by 1 millimeter at each click of a rotational button (ATTA Control), object of patent application BR 102020018402-4.
[013] O dispositivo ATTA Control é capaz de tracionar fibra ótica 1mm por click da engrenagem motora, sendo empregado por profissionais que não têm tanta habilidade para tracionar manualmente a fibra [013] The ATTA Control device is capable of pulling optical fiber 1 mm per click of the motor gear, being used by professionals who are not so skilled at manually pulling the fiber
[014] Em um aperfeiçoamento do dispositivo anterior ATTA Control, foi desenvolvido um dispositivo que não apresenta a engrenagem motora da fibra (ATTA Mini), sendo que o cirurgião é que traciona a fibra ótica manualmente, valendo-se de sua expertise para isto. [014] In an improvement of the previous ATTA Control device, a device was developed that does not have the fiber motor gear (ATTA Mini), and the surgeon pulls the optical fiber manually, using his expertise for this.
[015] Associado ao dispositivo simplificado existe um dispensador que contém uma capa plástica protetora da fibra. Esta capa serve para envolver a fibra e protegê-la contra contaminações de qualquer natureza, seja por microrganismos ou por sujidades variadas. [015] Associated with the simplified device is a dispenser that contains a plastic protective cover for the fiber. This cover serves to envelop the fiber and protect it against contamination of any kind, whether by microorganisms or by various types of dirt.
