Abstract
The trocar assembly of the present invention includes a tubular body portion, a sleeve, a unidirectional sealing means included within the sleeve and a funnel portion mounted around the sleeve. A perforating tool is insertable through the funnel, through the unidirectional sealing means and thence through the tubular portion of the trocar assembly into the body of a patient. All portions of the trocar assembly of the present invention are formed from materials which may not be readily sterilized by immersion in a sterilizing bath or autoclaving. Thus, the single use trocar assembly of the present invention may be only used once and will be destroyed if an attempt is made to resterilize the entire trocar assembly or any portion thereof.
Claims26
A single use non re-sterilizable device for guiding surgical tools into a body cavity comprising:
- a tubular body portion, said tubular body portion having a first and a second end;
- said first end of said tubular body portion constructed and arranged for insertion into a body cavity;
- said second end of said tubular body portion being formed into a sleeve;
- sealing means constructed and arranged to mount within said sleeve;
- said sealing means including unidirectional closing means;
- said tubular body portion and/or said sealing means being fabricated from a synthetic material that will be destroyed and rendered unusable by immersion into a sterilizing bath or autoclaving.
A single use non re-sterilizable medical trocar assembly comprising:
- a tubular body portion, said tubular body portion having a first end and a second end;
- said first end of said tubular body portion constructed and arranged for insertion into a body cavity;
- said second end of said tubular body portion being formed into a sleeve;
- sealing means constructed and arranged to mount within said sleeve;
- said sealing means including unidirectional closing means;
- a removable tool constructed and arranged to be insertable through said unidirectional closing means and through said tubular body portion into said body cavity;
- said tubular body portion, said sealing means, and/or said removable tool being fabricated from a synthetic material that will be destroyed and rendered unusable by immersion into a sterilizing bath or autoclaving.
A method of using a trocar assembly comprising the steps of:
- a. identifying an area of a tissue wall to be perforated;
- b. inserting a perforation device through a unidirectional seal in the tubular portion of a trocar assembly, said unidirectional seal being fabricated from a material which cannot be sterilized and will be rendered unusable by immersion or autoclaving;
- c. pressing the end of a said tubular portion of a trocar assembly against the identified area of said tissue wall, said tubular body portion of said trocar assembly being fabricated from a material which cannot be sterilized and would be rendered unusable when by immersion or autoclaving;
- d. pressing on the external end of a perforation device so that the head of said perforation device perforates said tissue wall, said perforation device being formed of a material which cannot be resterilized and would be rendered unusable by immersion in a sterilizing bath or autoclaving;
- and
- e. turning said tubular body portion of the trocar assembly into the tissue wall so that threads on the exterior of said tubular body portion engage the tissue wall.
