Method of using surgical drape

1. 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.

2. The method of claim 1 , wherein the canopy portion permits visual viewing of the transrectal device during the surgical treatment of the patient; and the torso portion comprises a perforation extending along a midline of the torso portion to assist in removal of the surgical drape from the patient.

3. The method of claim 2 , wherein the canopy portion maintains sterility of the treatment probe when the treatment probe is inserted into the urethra of the patient.

4. The method of claim 3 , wherein the perforation of the torso portion extends to the fenestration.

5. The method of claim 1 , wherein the canopy portion comprises a volume that is greater than a volume occupied by the proximal portion of the transrectal device.

6. The method of claim 5 , wherein the volume of the canopy portion is at least two times greater than the volume occupied by the proximal portion of the transrectal device.

7. The method of claim 5 , wherein the canopy portion comprises a thin flexible material having a thickness ranging from about 0.05 mm to about 3 mm.

8. The method of claim 5 , wherein the canopy portion is configured to collapse to less than its full volume in a free-standing configuration.

9. The method of claim 5 , wherein the canopy portion is configured to collapse to less than its full volume when the canopy portion is covering the proximal portion of the transrectal device.

10. The method of claim 1 , wherein the container comprises an attachment configured to releasably attach the container to an upper part of the second portion to support the container holding waste.

11. The method of claim 10 , wherein the attachment comprises tethers coupled to the upper part of the second portion from two sides of the opening of the container.

12. The method of claim 1 , wherein the container comprises a third sheet of material that is separable from a second sheet of material forming the canopy portion.

13. The method of claim 12 , wherein the second sheet of material is impervious to liquids.

14. The method of claim 1 , wherein the three-dimensional space defines a volume within a range from about 750 cm 3 to about 70,000 cm 3 .

15. The method of claim 1 , wherein the canopy portion is configured to wrap around at least the surgical arm coupled to the transrectal device or the proximal portion of the transrectal device such that the canopy portion collectively moves with the surgical arm and the proximal portion of the transrectal device.

16. The method of claim 1 , wherein the first portion and the second portion are detachably coupled to each other.

17. The method of claim 1 , wherein the container comprises a connector at a bottom of the container configured to connect to a suction system.

18. The method of claim 1 , wherein the container and the canopy portion are formed from a same sheet of material.

19. The method of claim 1 , wherein the second portion comprises a first sheet of material that is impervious to liquids.
