Method of using surgical drape

A method of covering a patient and a transrectal device during a surgical treatment of the patient, the method comprising:

• providing a surgical drape comprising a first portion and a second portion, the first portion comprising a canopy portion and a container, wherein the canopy portion comprises a rectangular protrusion on an upper sterile side of the surgical drape defining a three-dimensional space that is sized and shaped to cover a proximal portion of a transrectal device such that the proximal portion of the transrectal device is permitted to move within the three-dimensional space in a non-restrictive manner;
• positioning the first portion of the surgical drape with the canopy portion at least partially covering the proximal potion of the transrectal device so that a first side of the surgical drape is facing the proximal portion of the transrectal device, a second side of the surgical drape is facing opposite to the first side, and the canopy portion is configured to permit a user to manipulate the transrectal device through the canopy portion;
• positioning the container below the canopy portion such that an opening in the container allows waste generated during the surgical treatment to be received and stored in the container;
• providing a screen in an inner lower portion of the container to collect tissue when waste is passed through the screen, wherein the screen folds upon collapse of the container;
• inserting a treatment probe through a fenestration in the first portion of the surgical drape at a location that is above the canopy portion, from the second side, to provide access to a urethra of a patient;
• covering at least a part of a surgical arm coupled to the transrectal device and the proximal portion of the transrectal device with the surgical drape such that the canopy portion is capable of moving with the proximal portion of the transrectal device when the transrectal device is supported by the surgical arm;
• coupling the second portion of the surgical drape to the first portion of the surgical drape such that a torso portion of the second portion is coupled to the canopy portion of the first portion;
• and
• covering at least a portion of a torso of the patient with the torso portion of the surgical drape.
