A trocar surgical seal providing instrument access into a patient's body, the trocar surgical seal comprising:
- a first support to be positioned externally to a patient's body;
- a second support to be positioned within a patient's body;
- and
- a collapsible film passageway having a first end connected to the first support and a second end connected to the second support and having a non-adjustable length, the film passageway being disposed through an opening in a patient's body and in direct contact with the opening in the patient's body, the film passageway having a zero inner diameter due to compressive forces applied by the patient's body 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.
A trocar surgical seal providing instrument access through an access platform, the trocar surgical seal comprising
- a first support to be positioned externally to an access platform comprising a sealing cap removably coupled to a retractor;
- a second support being removably insertable through an opening in the sealing cap and to be positioned under the sealing cap;
- and
- a film passageway having a first end connected to the first support and a second end connected to the second support and portions of the film passageway being disposed within the opening in the sealing cap and in direct contact with the opening in the sealing cap, the film passageway having a non-adjustable length and providing a zero seal due to compressive forces applied by the sealing cap in direct contact with the film passageway and in absence of an inserted instrument through the first support and the film passageway.
A method for providing a surgical access system for introduction into a body cavity, the method comprising:
- providing an access platform comprising a sealing cap removably connected to a retractor, the retractor arranged to be inserted into a body cavity;
- and
- providing a trocar surgical seal comprising a first support, a second support and a film passageway connected to the first and second supports, the second support arranged to be inserted through the sealing cap and the film passageway providing a zero seal due to compressive forces applied by the sealing cap in direct contact with the film passageway and in absence of an inserted instrument through the first support and the film passageway.
