Abstract
The invention relates to a utility model pertaining to the field of surgical products for use in heart surgery, in particular for closing the patient's thorax, the device being placed underneath the sternum, preventing heart lesions during future surgical procedures, since when the sternum of a patient which has already been operated is opened from the front side, the heart might have adhered to the sternum and be cut by the saw, causing the patient to die. The heart protector comprises a device (1) formed by a thin and malleable titanium strip (2) having a mainly rectangular cross-section, with a variable width and provided over the entire edges thereof with an elastic material (3), preferably rubber, which forms part of the device (1) and is used to attach the plate between the sternum (4) and the heart (5), being tightened by metal wires (6).
Description
DISPOSIÇÃO CONSTRUTIVA APLÍCAPA EM PROTETOR CONSTRUCTIVE PROVISION PROVISION
CARDÍACO HEART
[001]Traía o presente relatório descritivo da patente de modelo de utilidade de uma nova disposição construtiva aplicada em protetor cardíaco, notadamente um dispositivo para ser implantado no tórax do indivíduo, de concepção inovadora e dotado de importantes melhoramentos tecnológicos e funcionais, segundo os mais modernos conceitos de engenharia e de acordo com as normas e especificações exigidas, revestindo-se de características próprias e dotadas com requisitos fundamentais de novidade e ato inventivo, fazendo resultar uma série de reais e extraordinárias vantagens técnicas, práticas e económicas. [001] This report describes the utility model patent of a new constructive arrangement applied in a cardiac protector, notably a device to be implanted in the chest of the individual, of innovative design and endowed with important technological and functional improvements, according to the most modern engineering concepts and in accordance with the required standards and specifications, having their own characteristics and endowed with fundamental requirements of novelty and inventive act, resulting in a series of real and extraordinary technical, practical and economic advantages.
ANTECEDENTES DA PATENTE PATENT BACKGROUND
[002]Como é do conhecimento dos técnicos no assunto, hoje em dia, em operações cardíacas, inexistem dispositivos que protejam especialmente o coração. Sobretudo doentes, quando reoperados, chegam até a morrer por falta de proteção do coração. Para minimizar esse problema, os cirurgiões procuram tomar muito cuidado quando serram o esterno de um doente, mas mesmo assim ainda acontecem acidentes, e o coração é lesado, podendo levar até a óbito. [002] As is well known to those skilled in the art today in cardiac operations, there are no devices that especially protect the heart. Especially sick, when reoperated, even die for lack of protection of the heart. To minimize this problem, surgeons try to be very careful when sawing a patient's sternum, but even then accidents still occur, and the heart is injured, possibly leading to death.
[003] Em vista disso, ao longo do tempo foram procedidos estudos visando eliminar todos esses problemas e inconvenientes e, como resultado, foi desenvolvido este modelo que possibilita a concepção de um inédito dispositivo, através do qual surge a possibilidade de proteger o coração quando da abertura do osso esterno por meio de serra, obtendo-se então um produto integrado com reais possibilidades de uma económica industrialização, minimizando custos, tempo de montagem e despesas de mão-de-obra, além de um efeito preciso de montagem, com melhores resultados e elevado
padrão de segurança. In view of this, studies have been conducted over time to eliminate all these problems and drawbacks, and as a result, this model has been developed that enables the design of an unprecedented device through which the possibility of protecting the heart arises when opening the sternum by sawing, resulting in an integrated product with real possibilities for economical industrialization, minimizing costs, assembly time and labor costs, as well as a precise assembly effect, with better results and high safety standard.
OBJETIVOS DA PATENTE PATENT OBJECTIVES
[004}A solução proposta é a de se utilizar o dispositivo objeto da presente patente logo abaixo do esterno no término da cirurgia, pois assim, na reoperação, não vai haver a hipótese de ser serrado o coração junto com o esterno, de modo que este dispositivo, sendo de material inerte, tal como preferencialmente o titânio, não causa reação e também não se adere ao coração. [004} The proposed solution is to use the device object of the present patent just below the sternum at the end of surgery, therefore, in reoperation, there will be no chance of sawing the heart along with the sternum, so that This device, being of inert material, such as titanium preferably, causes no reaction and also does not adhere to the heart.
[005]A vantagem é que nunca mais haverá este tipo de acidente, qual seja, o de lesar o coração com a serra, quando da passagem da serra, para abertura do esterno, [005] The advantage is that there will never be this kind of accident again, that is, injuring the heart with the saw when the saw passes to open the sternum,
[006JEstes e outros objetivos são alcançados com uma disposição que compreende um dispositivo formado por uma tira de titânio de secção predominantemente retangular e de largura, variável, pois cada doente tem o esterno de um tamanho e de uma largura própria, de modo que é necessário ter-se o referido dispositivo de vários tamanhos, para poder ser escolhido no momento da cirurgia, sendo certo que também deverá ter espessura fina, todavia que seja resistente o necessário para a serra não cortá-lo, mas que possa ser maleável para acompanhar a forma do esterno de cada doente. These and other objects are achieved with an arrangement comprising a device formed by a titanium strip of predominantly rectangular section and variable width, as each patient has a sternum of its own size and width, so that it is necessary said device of various sizes may be selected at the time of surgery, although it must also be of a thin thickness, although it is sturdy enough for the saw not to cut it but may be malleable to accompany the sternum shape of each patient.
[007]Referido dispositivo é provido ainda em toda sua borda de material elástico, preferencialmente borracha, sendo parte do referido dispositivo e que servirá para fixar a placa sobre o esterno, pois os fios metálicos hoje utilizados para o fechamento do esterno, serão apertados justamente nesta borracha, e que isto também ajudará para que o esterno não se rompa em um eventual "abuso" do paciente no pós-operatório, pois não deixará o fio escorregar, pois ficará preso no dispositivo. Said device is still provided in all its edge of elastic material, preferably rubber, being part of said device and that will serve to fix the plate on the sternum, since the metallic wires used today for closing the sternum, will be tightened tightly. This rubber will also help to prevent the sternum from rupturing a possible "abuse" of the patient postoperatively, as it will not let the wire slip, as it will get caught in the device.
