Abstract

Claims (27)

1 . A surgical robotic access system providing instrument access into a patient's body, the surgical robotic access system comprising:

a surgical robotic access platform having a proximal portion and a distal portion, the proximal portion of the surgical robotic access platform including a flexible seal; and

a robotic sheath comprising a proximal cover and a distal cover, wherein the proximal cover comprises two arcuate side walls configured to cover portions of a robotic manipulator inserted through the robotic sheath, and wherein each of the proximal cover and the distal cover comprise a cavity through which the robotic manipulator is allowed to be inserted, seated within, and moved therethrough,

wherein the robotic sheath further comprises a vertical slit that extends between the two arcuate side walls, and wherein the vertical slit allows the two arcuate side walls to move away from each other.

2 . The surgical robotic access system of claim 1 , wherein the robotic sheath is configured to expand to accommodate different robotic manipulators having different sizes and shapes.

3 . The surgical robotic access system of claim 1 , wherein the robotic sheath further comprises smooth outer surfaces for the two arcuate side walls, wherein the smooth outer surfaces minimize friction between the robotic sheath and the surgical robotic access platform.

4 . The surgical robotic access system of claim 1 , wherein the robotic sheath further comprises smooth inner surfaces for the two arcuate side walls, wherein the smooth inner surfaces minimize damage to the robotic manipulator inserted therethrough.

5 . The surgical robotic access system of claim 1 further comprising a horizontal slit configured to separate the two arcuate side walls from the distal cover, the horizontal slit allowing the distal cover to separate from the proximal cover and the proximal cover to expand.

6 . The surgical robotic access system of claim 1 , wherein the cavity of the distal cover is interconnected to the cavity of the proximal cover.

7 . The surgical robotic access system of claim 1 , wherein the distal cover is configured to be displaced away from the proximal cover to provide an unobstructed pathway from a proximal opening in the proximal cover to a distal opening in the proximal cover.

8 . The surgical robotic access system of claim 1 wherein the proximal cover further comprises a tail, wherein the tail is configured to support the robotic manipulator.

9 . The surgical robotic access system of claim 8 , wherein the tail is configured to facilitate insertion of the robotic sheath into the surgical robotic access platform.

10 . The surgical robotic access system of claim 8 , wherein the tail is configured to facilitate removal of the robotic sheath from the surgical robotic access platform.

11 . The surgical robotic access system of claim 1 , wherein the distal cover is hemispherical-shaped.

12 . The surgical robotic access system of claim 1 , wherein the distal cover has a proximal opening but no distal opening, the distal cover configured to encase the robotic manipulator therein.

13 . The surgical robotic access system of claim 1 , wherein the distal cover comprises a proximal opening configured to connect with the cavity of the proximal cover.

14 . The surgical robotic access system of claim 13 , wherein the distal cover comprises a distal opening coupled to the proximal opening of the distal cover.

15 . A surgical robotic access system providing instrument access into a patient's body, the surgical robotic access system comprising:

a surgical robotic access platform having a proximal portion and a distal portion; and

a robotic sheath comprising a proximal cover and a distal cover, wherein the proximal cover comprises two side walls configured to cover a robotic manipulator inserted through the robotic sheath, and wherein the robotic sheath defines a cavity through which the robotic manipulator is to be inserted, seated within, and moved therethrough,

wherein the robotic sheath further comprises one or more slits configured to allow the robotic sheath to expand to accommodate the robotic manipulator; and

wherein a distance between the two side walls separated by the one or more slits is between 2 to 4 millimeters.

16 . A surgical robotic access system providing instrument access into a patient's body, the surgical robotic access system comprising:

a surgical robotic access platform having a proximal portion and a distal portion; and

a robotic sheath comprising a proximal cover and a distal cover, wherein the proximal cover comprises two side walls configured to cover a robotic manipulator inserted through the robotic sheath, and wherein the robotic sheath defines a cavity through which the robotic manipulator is to be inserted, seated within, and moved therethrough,

wherein the robotic sheath further comprises one or more slits configured to allow the robotic sheath to expand to accommodate the robotic manipulator; and

wherein the two side walls and the one or more slits being arranged between the two side walls further comprise a bridge configured to connect the two side walls, the bridge being configured to resist a distal movement of the robotic manipulator being insertable through the robotic sheath and to resist a separation of the two side walls from each other.
