Description
APERFEIÇOAMENTO EM VEDAÇÃO DE TROCATERCAMPO DA INVENÇÃOIMPROVEMENT OF THE INVENTION EXCHANGE FIELD
A presente invenção diz respeito a um aperfeiçoamento emvedação de trocater. Mais especificamente compreende um vedantedescartável para trocater produzido em silicone biocompatível queapresenta uma configuração que minimiza o fluxo de gás no sentidode fuga e permite a introdução e retirada de instrumentos de formasuave.The present invention relates to an improved trocar sealing. More specifically it comprises a disposable trocar sealant made of biocompatible silicone which has a configuration that minimizes gas flow in the sense of leakage and allows for the introduction and removal of softly shaped instruments.
ANTECEDENTES DA INVENÇÃOBACKGROUND OF THE INVENTION
A cirurgia vídeolaparoscópica é realizada com a ajuda deinstrumental e aparelhagem adequada para que seja obtida umavisualização da cavidade abdominal sem que haja a necessidade degrandes incisões e consequentemente com um menor traumacirúrgico. Este tipo de intervenção necessita então, que a cavidadeabdominal seja transformada de virtual em real com a insuflação de gás.Video-laparoscopic surgery is performed with the aid of instrumental and adequate equipment to obtain a visualization of the abdominal cavity without the need for large incisions and consequently with minor trauma. This type of intervention then requires that the abdominal cavity be transformed from virtual to real with gas insufflation.
No caso de procedimentos intra-abdominais, o uso deinstrumental é indispensável. Assim é necessário que as pinçasobtenham acesso à cavidade peritoneal, sem que o gás escape com aperda do campo operatório.In the case of intra-abdominal procedures, the instrumental use is indispensable. Thus it is necessary for the forceps to gain access to the peritoneal cavity without the gas escaping tightly from the operative field.
Os trocateres são os instrumentos que permitem a realizaçãodestes procedimentos, sendo dotados de vedações para evitar ovazamento de gás. O mecanismo de vedação é posicionado dentro dacâmara do alojamento de trocarter, vedando contra a superfícieexterna dos instrumentos inseridos, impedindo ou minimizando asaída dos fluídos e dos gases de insuflação das cavidade corporalatravés da cânula de trocarte.The trocars are the instruments that allow the accomplishment of these procedures, being equipped with seals to avoid the gas leakage. The sealing mechanism is positioned within the chamber of the trocar housing, sealing against the outer surface of the inserted instruments, preventing or minimizing the outflow of body cavity fluids and gases through the trocar cannula.
O estado da técnica descreve conjuntos de vedação duplos, comuma vedação proximal usada para vedar em torno do instrumento,euma vedação de bico de pato proporcionada abaixo da vedaçãoproximal para vedar o alojamento do trocarte quando o instrumentonão está presente.The prior art describes double seal assemblies, with a proximal seal used to seal around the instrument, a duckbill seal provided below the proximal seal to seal the trocar housing when the instrument is not present.
Outros trocateres empregam um único mecanismo de vedação,geralmente um dispositivo de silicone dotado de um orifício comdiâmetro de abertura menor que o diâmetro do instrumento a serusado em conjunto com o trocarte.Other trocars employ a single sealing mechanism, usually a silicone device having a hole with an opening diameter smaller than the diameter of the instrument to be used in conjunction with the trocar.
No entanto, estas vedações de trocateres apresentam oinconveniente de serem de difícil montagem no trocater devido aoinúmeros componentes constituintes do dispositivo vedante. Ainda, osdispositivos apresentam um ponto de vedação de frágil resistência, oque pode gerar o rompimento em função do atrito com o instrumento.However, these trocar seals have the drawback of being difficult to assemble on the trocar due to the numerous constituent components of the sealing device. Still, the devices have a weak resistance sealing point, which can generate the rupture due to the friction with the instrument.
Dessa forma, existe a necessidade de prover um dispositivo devedação de trocateres que mantenha o pneumoperitôneo durante todoo procedimento, inclusive na introdução e retirada dos instrumentos,provendo mínimo atrito com os instrumentos, tal aperfeiçoamento emdispositivo de vedação de trocater sendo descrito e reivindicado nopresente pedido.Thus, there is a need to provide a trocar sealing device that maintains the pneumoperitoneum throughout the procedure, including the introduction and removal of the instruments, providing minimal friction with the instruments, such an improvement in trocar sealing device being described and claimed upon request.

DETAILED DESCRIPTION OF THE INVENTION
O aperfeiçoamento em vedação de trocater, objeto da presenteinvenção, compreende um elemento de vedação de silicone a serposicionado na parte interna do trocater, com o objetivo de restringir afuga de gás durante o procedimento cirúrgico mediante umainovadora geometria que permite que o fluxo do gás no sentido defuga seja minimizado.The improvement in trocar sealing, object of the present invention, comprises a silicone sealing element to be positioned inside the trocar, with the purpose of restricting gas leakage during the surgical procedure by means of an innovative geometry that allows gas flow in the direction defuga is minimized.
O elemento de vedação compreende um corpo cilíndrico queinclui uma abertura circular (10) em uma das extremidades eextremidade oposta à dita abertura circular (10) dotada de uma base (11).The sealing element comprises a cylindrical body including a circular opening (10) at one end and opposite to said circular opening (10) provided with a base (11).
A base (11) apresenta na superfície a disposição de cortes (111)que permitem a passagem dos instrumentos, ditos cortes (111) queem função da resiliência do material garantem a vedação quando nãohá instrumento posicionado no trocater, conforme apresentando nafigura 3B.The base (11) has on its surface the arrangement of cuts (111) that allow the passage of the instruments, said cuts (111) that, due to the material resilience, guarantee the sealing when there is no instrument positioned in the trocar, as shown in figure 3B.
Na superfície do corpo cilíndrico e contíguo à abertura circular(10) é disposta uma área circundante dotada de alargamento dediâmetro (12).On the surface of the cylindrical body adjacent to the circular aperture (10) is arranged a surrounding area provided with diameter widening (12).
Entre a área de alargamento de diâmetro (12) e a extremidadedotada de base (11) é disposta uma área com diâmetro igual àmedida de diâmetro da abertura circular (10), em dita área sendodispostos raios em formato côncavo (13) na superfície interna eexterna, ditos raios côncavos (13) intercalados e equidistantes.Between the diameter enlargement area (12) and the base end (11), an area with a diameter equal to the diameter of the circular aperture (10) is arranged, in which area concave shaped rays (13) are disposed on the inner and outer surface. said interleaved and equidistant concave rays (13).
Os raios côncavos (13) geram na superfície da base (11) recuossemi-circulares (112) alinhados com os raios côncavos (13), ditosrecuos intercalados com prolongamentos (113) alinhados com operímetro da abertura circular (10) disposta na extremidade oposta docorpo cilíndrico.The concave rays (13) generate on the surface of the base (11) recesses semicircular (112) aligned with the concave rays (13), interspersed recesses with extensions (113) aligned with the circular opening operimeter (10) disposed at the opposite end of the body cylindrical.
O corpo cilíndrico de silicone apresenta flexibilidade e os raioscôncavos (13) mantém a estruturação, mantendo o formato original.The cylindrical silicone body has flexibility and the concave radii (13) maintain the structure, maintaining the original shape.
Conforme apresentado na figura 1, o elemento de vedação (100)é posicionado e fixado na câmara do trocarter (200) medianteinserção da estrutura anelar disposta no entorno do bocal junto à basedo trocater, apresentando uma interferência dimensional entre oelemento vedante e a base do trocater que promove o ajuste e oencaixe perfeito tendo em vista o corpo do elemento de vedação serproduzido em silicone, o que permite a maleabilidade.As shown in Figure 1, the sealing member (100) is positioned and fixed to the trocar chamber (200) by inserting the annular structure disposed around the nozzle next to the trocar base, presenting dimensional interference between the sealing element and the base of the trocar. which promotes perfect fit and fit in view of the sealing element body being made of silicone, which allows for malleability.
