Abstract

A surgical drape for a patient side cart of a teleoperated surgical system may include a body and an attachment device feature. The body may be sized and shaped to cover at least a portion of an arm or main column of the patient side cart. The attachment device feature may be connected to the body. The attachment device feature may be configured to install the surgical drape to the arm or main column so as to cover at least a portion of the arm or main column with the surgical drape. The attachment device feature may be detectable by a sensor in an installed position of the surgical drape on the arm or main column. At least one of the main column and the arm may include a sensor to detect an attachment device feature of a surgical drape.

First claim

What is claimed is:

1. A system comprising:
a patient side cart and a surgical drape;
the patient side cart comprising:
a base,
a main column connected to the base,
an arm connected to the main column to support a surgical instrument, and
a sensor on one or both of the main column and the arm; and

the surgical drape comprising:
a body sized and shaped to cover at least a portion of the arm or main column of the patient side cart,
an attachment device feature connected to the body, the attachment device feature being configured to install the surgical drape to the arm or main column in a position covering at least a portion of the arm or main column with the surgical drape,
a cable support feature coupled to the body, the cable support feature being arranged to route and support one or more electrical or data cables, and
a clip attached to an end of the body and configured to be engaged with a spar portion of the arm of the patient side cart, the spar portion being configured to permit translational movement to the surgical instrument installed at the arm;

wherein at least one of the main column and the arm includes a sensor that, in an installed position of the surgical drape on the arm or main column, the attachment device feature is positioned at a location in sensing proximity of the sensor, and the sensor detects a presence of the attachment device feature of the surgical drape.

2. The system of claim 1 , wherein at least one of the main column and the arm includes an attachment device feature complementary to the attachment device feature of the surgical drape.

3. The system of claim 2 , wherein the attachment device feature of the main column and the arm is a magnet.

4. The system of claim 3 , wherein the sensor is an inductive sensor.

5. The system of claim 3 , wherein the magnet has a ring shape.

6. A surgical drape for a patient side cart of a teleoperated surgical system, the surgical drape comprising:
a body sized and shaped to cover at least a portion of an arm or main column of the patient side cart;
an attachment device feature connected to the body, the attachment device feature being configured to install the surgical drape to the arm or main column in a position covering at least a portion of the arm or main column with the surgical drape;
a cable support feature coupled to the body, the cable support feature being arranged to route and support one or more electrical or data cables; and
a clip attached to an end of the body and configured to be engaged with a spar portion of the arm of the patient side cart, the spar portion being configured to permit translational movement to a surgical instrument installed at the arm;
wherein, in an installed position of the surgical drape on the arm or the main column, the attachment device feature is positioned at a location in sensing proximity of a sensor of the patient side cart.

7. The surgical drape of claim 6 , wherein the body comprises a material chosen from at least one of: thermoplastic polyurethane, ultra high molecular weight polyethylene, low density polyethylene, or high density polyethylene.

8. The surgical drape of claim 7 , wherein the body comprises thermoplastic polyurethane.

9. The surgical drape of claim 8 , wherein the body further comprises a lubricant filler.

10. The surgical drape of claim 8 , wherein the body is a single layer of thermoplastic polyurethane.

11. The surgical drape of claim 6 , wherein the attachment device feature comprises metal.

12. The surgical drape of claim 11 , wherein the attachment device feature is detectable by an inductive sensor.

13. The surgical drape of claim 6 , further comprising an additional attachment device feature coupled to the cable support feature to connect the cable support feature to the arm or main column in the installed position of the surgical drape.

14. The surgical drape of claim 6 , wherein the cable support feature is coupled to the attachment device feature.

15. The surgical drape of claim 6 , further comprising one or more malleable strips configured to support the surgical drape, in the installed position, in a shape that provides a space between the surgical drape and the arm or main column.

16. The surgical drape of claim 6 , wherein the attachment device feature is part of a magnetic attachment device.

17. The surgical drape of claim 6 , wherein:
the body is sized and shaped to cover at least a portion of the arm; and
in the installed position of the surgical drape on the arm, the cable support feature is positioned to route the one or more electrical or data cables along at least a portion of the arm.

18. The surgical drape of claim 6 , wherein:
the body is sized and shaped to cover at least a portion of the main column; and
in the installed position of the surgical drape on the main column, the cable support feature is positioned to route the one or more electrical or data cables along at least a portion of the main column.

19. The surgical drape of claim 6 , wherein in the installed position of the surgical drape on the arm or the main column, the cable support feature is positioned to route the one or more electrical or data cables on a side of the surgical drape facing away from the arm or the main column.
