A trocar surgical seal for providing instrument access into a patient's body or through a sealing cap removably coupled to a retractor of an access platform for providing instrument access into a patient's body, the surgical seal comprising: a first support to be positioned externally to a patient's body or externally of a sealing cap of an access platform; a second support to be positioned within a patient's body or to be positioned internally of a sealing cap of an access platform; and a collapsible film passageway having a first end connected to the first support and a second end connected to the second support, the film passageway being intended to in use be disposed through an opening in a patient's body or a sealing cap and in direct contact with the opening in the patient's body or sealing cap, the film passageway having a zero inner diameter when exposed in use to compressive forces applied by the patient's body or the sealing cap in direct contact with the film passageway in absence of an instrument inserted through the film passageway and providing an instrument seal with an instrument inserted through and in direct contact with the film passageway; characterized in that the film passageway is non-elastic, has a non-adjustable length and has a thickness between .01 to .05 millimeters that prevents the film passageway from retracting the opening in the patient's body and resists extension or forces to stretch the film passageway in a longitudinal direction, wherein the film passageway is collapsed prior to insertion into the patient's body or into the sealing cap and remains collapsed in an operational state when no instrument is within the film passageway, the properties and thickness of the film being such that in use the film passageway is intended to collapse under radial or circumferential compressive forces exerted by a body wall or sealing cap, the trocar surgical seal being incapable of counteracting such forces. a first support to be positioned externally to a patient's body or externally of a sealing cap of an access platform; a second support to be positioned within a patient's body or to be positioned internally of a sealing cap of an access platform; and a collapsible film passageway having a first end connected to the first support and a second end connected to the second support, the film passageway being intended to in use be disposed through an opening in a patient's body or a sealing cap and in direct contact with the opening in the patient's body or sealing cap, the film passageway having a zero inner diameter when exposed in use to compressive forces applied by the patient's body or the sealing cap in direct contact with the film passageway in absence of an instrument inserted through the film passageway and providing an instrument seal with an instrument inserted through and in direct contact with the film passageway; characterized in that the film passageway is non-elastic, has a non-adjustable length and has a thickness between .01 to .05 millimeters that prevents the film passageway from retracting the opening in the patient's body and resists extension or forces to stretch the film passageway in a longitudinal direction, wherein the film passageway is collapsed prior to insertion into the patient's body or into the sealing cap and remains collapsed in an operational state when no instrument is within the film passageway, the properties and thickness of the film being such that in use the film passageway is intended to collapse under radial or circumferential compressive forces exerted by a body wall or sealing cap, the trocar surgical seal being incapable of counteracting such forces. <EOS>
