[001 ] O presente modelo de utilidade está relacionado à área médica, mais especificamente trata o presente modelo de um aplicador de um dispositivo para dilatação do canal endocervical (canal interno do colo do útero). The present utility model is related to the medical field, more specifically it treats the present model of an applicator of a device for dilatation of the endocervical canal (internal canal of the cervix).
[002] A estenose, ou seja, o estreitamento do canal do colo do útero (endocervical) é a mais importante das complicações apôs uma cirurgia no colo do útero. As repercussões clínicas podem variar de cólicas menstruais, seguida de hematométrio (acúmulo de sangue no interior do útero), infertilidade e dificuldade de detecção precoce de recidiva e/ou recorrência de lesão pré~maSigna. Estudos mostram o índice de estenose do canal cervical variando de 1 ,3 a 19.0% quando realizada cirurgia com alça de alta frequência. [002] Stretching, that is, narrowing of the cervical canal (endocervical) is the most important complication after cervical surgery. The clinical repercussions may vary from menstrual cramps, followed by hematometrial (blood accumulation inside the uterus), infertility and difficulty in the early detection of recurrence and / or recurrence of pre-mensign lesion. Studies show the stenosis index of the cervical canal varying from 1, 3 to 19.0% when performed with high frequency loop surgery.

Figura 10 - mostra a vista em perspectiva do dispositivo dilatador inserido no apiicador. Figure 10 shows the perspective view of the dilator device inserted in the applicator.
[020] O dispositivo (40) diiatador deve ser introduzido no aplicador. Â ponta (1 1 ) é inserida no orifício (42) do apiicador, sendo a curvatura (12), o comprimento, e o diâmetro do duto (41 ) adequados para a passagem pela porção (10) distai com facilidade. A porção (10) distai, por ser mais fina e produzida em material plástico, possui certa flexibilidade o que favorece a introdução do dispositivo (40). Essa flexibiiidade também é necessária para favorecer a introdução da porção (10) distai no canal endocervicai estreitado. [020] The dialing device (40) must be inserted into the applicator. The tip 11 is inserted into the bore 42 of the implement, the curvature 12, length, and duct diameter 41 being suitable for passage through the distal portion 10 easily. The distal portion 10, being thinner and produced from plastic material, has some flexibility which favors the introduction of the device 40. Such flexibility is also necessary to favor introduction of the distal portion (10) into the narrowed endocervical canal.
[021 ] O dispositivo (40) dilatador é introduzido na região (10) distai do aplicador até encontrar o rebaixo (21 ) radiai. A parte externa do disco (43) se apoia no aplicador não permitindo a continuidade do deslocamento do dispositivo (40) peio aplicador. Assim, o dispositivo (40) fica posicionado na porção (13) reta para a introdução na paciente. O disco (43) do dispositivo (40) dilatador possui ainda uma pluralidade de orifícios (44) para a sutura, The dilator device (40) is introduced into the distal region (10) of the applicator until the radial recess (21) is encountered. The outside of the disc (43) rests on the applicator not allowing continuity of displacement of the applicator device (40). Thus, the device (40) is positioned in the straight portion (13) for introduction into the patient. The disc (43) of the The dilator device (40) further has a plurality of sutures (44) for suturing,
[022] O presente aplicador é dotado então de uma porção (10) distai de diâmetro menor que a porção (20) proximal, a fim de vantajosamente formar um rebaixo (21 ) radial. The present applicator is then provided with a distal portion (10) of smaller diameter than the proximal portion (20), advantageously to form a radial undercut (21).
[023] A ponta (1 1 ) abaulada é primeiramente introduzida no canal vaginal da paciente até encontrar a região cervical. A ponta (1 1 ) do aplicador é introduzida na sequência no canal endocervical estreitado. Dessa forma, essa ponta é vantajosamente abaulada para que possa ser introduzida no canal cervical enrijecido e estreitado. [023] The bulged tip (11) is first inserted into the vaginal canal of the patient until the cervical region is found. The tip (11) of the applicator is inserted into the sequence in the narrowed endocervical canal. In this way, this tip is advantageously bulged so that it can be introduced into the narrowed and narrowed cervical canal.
[024] Logo que o cirurgião consegue introduzir a ponta (1 1 ) no canal endocervical o mesmo continua a introduzir o aplicador até que o a extermidade (45) do duto (41 ) seja introduzida no canal endocervical. Ao se continuar introduzindo o aplicador a porção interna do disco (43) irá encontrar o ectocervix. Nesse momento, o cirurgião poderá simplesmente retirar o aplicador, estando o dispositivo (40) posicionado corretamente para a finalização da cirurgia por meio da fixação com pontos do dispositivo dilatador em 04 pontos cardeais no colo do útero (3,6,9 e 12h). [024] As soon as the surgeon is able to insert the tip (11) into the endocervical canal, it continues to introduce the applicator until the end (45) of the duct (41) is introduced into the endocervical canal. By continuing to insert the applicator into the inner portion of the disc (43) you will find the ectocervix. At that time, the surgeon may simply withdraw the applicator, the device (40) being correctly positioned for completion of the surgery by means of stitch attachment of the dilator device at 4 cardinal points in the cervix (3, 9, 9, and 12 h) .
[025] O aplicador é dotado ainda de uma porção (30) proximal que funciona como um cabo para o manuseio do cirurgião. Essa porção (30) proximal possui diâmetro preferencialmente maior que a porção (20) medial. A porção (20) medial possui comprimento compatível com o canal vaginal, sendo que a sua introdução auxiiia o cirurgião a se orientar quanto ao posicionamento correio no dispositivo (40) dilatador na maioria das pacientes. [025] The applicator is further provided with a proximal portion (30) which functions as a handle for the surgeon's handling. This proximal portion (30) is preferably larger in diameter than the portion (20) medial. The medial portion 20 has a length compatible with the vaginal canal, and its introduction helps the surgeon to orient himself to mail positioning in the dilator device 40 in most patients.
[026] Ã porção (30) próxima! é dotada ainda de cabo dotado de um chanfro (31 ) que serve para o cirurgião apoiar o dedo poiegar e ao mesmo tempo marcar a direção de curvatura da porção (10) distai, orientando o cirurgião durante o procedimento cirúrgico. Sem o chanfro (31 ), o cirurgião não saberia com facilidade a posição da curvatura (12). O chanfro (31 ) promove ainda mais apoio de evita a rotação do aplicador. A porção (30) próxima! é dotada ainda de uma pluralidade de ranhuras (32) preferencialmente transversais que favorecem o atrito entre a porção distai e a mão do cirurgião promovendo ainda mais firmeza. [026] Next portion (30)! is further provided with a cable provided with a bevel (31) which serves for the surgeon to support the finger and at the same time mark the direction of curvature of the distal portion (10), guiding the surgeon during the surgical procedure. Without the bevel (31), the surgeon would not easily know the position of the curvature (12). The chamfer (31) further promotes support to prevent rotation of the applicator. The next portion (30)! is further provided with a plurality of preferably transverse grooves (32) which favor friction between the distal portion and the hand of the surgeon further promoting firmness.
