Abstract

The dilator is in the form of an inflatable ring, circular, oval or elliptical in shape, equipped with projections which are also inflatable and hold it in position inside the cavity of the organ being dilated. The dilator is made from a biocompatible material, especially latex, teflon or a polymer, and its inflation can be controlled by a valve inside or outside the body, e.g. using a gas which is employed in coelio-surgery. After use, the dilator is deflated and withdrawn from the body.

Description

ECARTEUR ENDOCAVITAIRE. ENDOCAVITY RETRACTOR.

~Cette invention s'applique à la chirurgie laparoscopique,ou coelioscopique, transcutanée,au cours de laquelle une cavité(coelomeou autre)est dilatée ele facog à permettre des actes techniques sans incision large des téguments. ~ This invention applies to laparoscopic surgery, or laparoscopic, transcutaneous, during which a cavity (coelome or other) is dilated ele facog to allow technical acts without wide incision of the integuments.

Les écarteurs dont nous disposons actuellement sont rigides ou articulés,
et souvent insuffisants pour maintenir un champ opératoire libre.The spacers we currently have are rigid or articulated,
and often insufficient to maintain a free operating field.

Ils necessitent de fréquents repositionnements,qui sont à l'origine de
pertes de temps et de lésions tissulaires.They require frequent repositionings, which are at the origin of
wasted time and tissue damage.

écarteur endocavitaire est une structure gonflable dont la matière sera
biocompatible,de forme annulaire,ovoide,ou elliptique,et qui isolera
une partie du champ opératoire,en maintenant écartées les structures
avoisinantes.endocavitary retractor is an inflatable structure whose material will be
biocompatible, annular, ovoid, or elliptical, which will isolate
part of the operating field, keeping the structures apart
neighboring.

Il sera maintenu en place par le gonflement simultané de prolongements
s'appuyant sur les limites de la cavité où l'on a choisi de travailler
par exemple un second anneau,solidarisé au premier par plusieurs tubes
perpendiculaires au plan formé par 1 'écarteur. It will be held in place by the simultaneous swelling of extensions
based on the limits of the cavity where we chose to work
for example a second ring, joined to the first by several tubes
perpendicular to the plane formed by the spacer.

L'écarteur est introduit dégonflé,par l'un des trocards,amené au contact
de la zone à opérer,puis. gonflé,soeit par une valve en dehors du patient,
soit par une valve au contact de l'anneau.The retractor is introduced deflated, by one of the trocards, brought into contact
of the area to be operated on, then. swollen, either by a valve outside the patient,
either by a valve in contact with the ring.

Une fois- positionne,l écarteur est autostatique,puisque ses prolongements
le bloquent dans la cavité.Once positioned, the retractor is autostatic, since its extensions
block it in the cavity.

En fin d'1nte#vention,il est-dégonfle puis retire,comme une pièce
anatomique At the end of 1 nte # vention, it is-deflates then withdraws, like a piece
anatomical
