Abstract

An interface for moveably interconnecting a surgical table with a stationary gantry supporting a surgical robotic system is provided. The interface includes a collar portion, an actuator portion, and a locking portion. The collar portion is attached relative to a longitudinal cross-member of the surgical table via receipt of a portion of the longitudinal cross-member through the collar portion. The actuator portion is one of attached to the collar portion and attached to and/or supported by the gantry, and includes gearing operatively engaged to gearing attached to the longitudinal cross member. The locking portion is attached to and/or supported relative to the gantry, and includes a shoulder portion configured to contact an exterior surface of the collar portion, and at least one engagement portion moveable between a disengaged position and an engaged position. After the exterior surface is contacted to the shoulder portion, the locking portion can be moved from the disengaged position to the engaged position to maintain the position of the collar portion relative to the stationary gantry. And, after the collar portion is maintained in position relative to the stationary gantry, actuation of the actuator portion drives interaction of the gearing that moves portions of cross member into and out of the collar portion in a first linear direction and a second linear direction.

First claim

We claim:

1 . An interface for moveably interconnecting a surgical table with a stationary gantry supporting a surgical robotic system, the interface comprising:
a collar portion attached relative to a longitudinal cross member of the surgical table, the collar portion including a first end, an opposite second end, an interior cavity extending between the first end and the second end, an exterior surface positioned between the first end and the second end, and an interior surface defining a portion of the interior cavity, portions of the longitudinal cross member being moveably received in the interior cavity; an actuator portion attached to one of the collar portion and the gantry, the actuator portion being configured to actuate a first gear portion provided in the interior cavity of the collar portion, and the first gear portion being configured to operatively engage a second gear portion attached to the longitudinal cross member; and a locking portion attached to and/or supported relative to the gantry, the locking portion including at least one engagement portion moveable between a disengaged position and an engaged position; wherein the locking portion can be moved from the disengaged position to the engaged position to maintain a position of the collar portion relative to the stationary gantry; and wherein, after the collar portion is maintained in position relative to the stationary gantry, the first gear portion is operatively engaged to the second gear portion, and actuation of the actuator portion drives movement of portions of the longitudinal cross member into and out of the interior cavity via interaction between the first gear portion and the second gear portion to correspondingly adjust positions of the surgical table relative to the gantry.

2 . The interface of claim 1 , wherein the first gear portion is a circular gear and the second gear portion is a linear gear, and wherein rotation of the circular gear in a first rotational direction moves the longitudinal cross member in a first linear direction relative to the collar portion, and rotation of the circular gear in an opposite second rotational direction moves the longitudinal cross member in an opposite second linear direction relative to the collar portion.

3 . The interface of claim 2 , wherein movement of the longitudinal cross member in the first and second linear directions relative to the collar portion correspondingly moves the surgical table in the first and second linear directions relative to the stationary gantry to afford positioning and repositioning of a patient supported by the surgical table relative to the surgical robotic system supported by the stationary gantry.

4 . The interface of claim 3 , further comprising at least one truck attached to the interior surface of the interior cavity of the collar portion, and at least one track portion attached to an exterior surface of the longitudinal cross member; and wherein the at least one truck and the at least one track engage one another within the interior cavity of the collar portion, and engagement of the at least one truck and the at least one track guides movement of the collar portion relative to the longitudinal cross member.

5 . The interface of claim 1 , further comprising at least one truck attached to the interior surface of the interior cavity of the collar portion, and at least one track portion attached to an exterior surface of the longitudinal cross member; and wherein the at least one truck and the at least one track engage one another within the interior cavity of the collar portion, and engagement of the at least one truck and the at least one track guides movement of the collar portion relative to the longitudinal cross member.

6 . The interface of claim 5 , wherein the first gear portion is a circular gear and the second gear portion is a linear gear, and wherein rotation of the circular gear in a first rotational direction moves the longitudinal cross member in a first linear direction relative to the collar portion, and rotation of the circular gear in an opposite second rotational direction moves the longitudinal cross member in an opposite second linear direction relative to the collar portion.

7 . The interface of claim 6 , further comprising an outrigger portion attached to and/or supported relative to the gantry, the outrigger portion including a first side surface and a second side surface; and wherein the collar portion includes a receiving area defined in part by one or more bumpers attached to the collar portion on a first side of the receiving area and one or more bumpers attached to the collar portion on a second side of the receiving area, the outrigger portion being receivable in the receiving area, and contact of the one or more bumpers on the first side of the receiving area with the first side surface of the outrigger and contact of the one or more bumpers on the second side of the receiving area with the second side surface of the outrigger serving to guide the collar portion into position relative to the gantry.

8 . The interface of claim 7 , wherein the engagement portion of the locking portion includes a first post portion and a second post portion moveable from an undeployed position that allows passage of the collar portion over the locking portion to a deployed position that prevents movement of the collar portion when the exterior surface thereof is contacted to the gantry.

9 . An interface for moveably interconnecting a surgical table with a stationary gantry supporting a surgical robotic system, the interface comprising:
a collar portion attached relative to a longitudinal cross member of the surgical table, the collar portion including a first end, an opposite second end, an interior cavity extending between the first end and the second end, an exterior surface positioned between the first end and the second end, an interior surface defining a portion of the interior cavity, and a receiving area defined in part by one or more bumpers attached to the collar portion, portions of the longitudinal cross member being moveably received in the interior cavity; an actuator portion attached to one of the collar portion and the gantry, the actuator portion being configured to actuate a first gear portion provided in the interior cavity of the collar portion, and the first gear portion being configured to operatively engage a second gear portion attached to the longitudinal cross member; an outrigger portion attached to and/or supported relative to the gantry, the outrigger portion including a first side surface and a second side surface; and a locking portion supported by the outrigger portion, the locking portion including at least one engagement portion moveable between a disengaged position and an engaged position; wherein the outrigger portion is receivable in the receiving area, and contact of the one or more bumpers to at least one of the first side and the second side of the outrigger portion serves to guide the collar portion into position relative to the gantry; wherein, after the outrigger portion is received in the receiving area, and the exterior surface is contacted to the gantry, the locking portion can be moved from the disengaged position to the engaged position to secure the collar portion in position; and wherein, after the collar portion is secured, the first gear portion is operatively engaged to the second gear portion, and actuation of the actuator portion drives movement of portions of the longitudinal cross member into and out of the interior cavity via interaction between the first gear portion and the second gear portion to correspondingly adjust positions of the surgical table relative to the gantry.
