Abstract

A medical device drive system may include a locking structure, a locking device sized and shaped to engage with the locking structure, the locking device coupled to a drive system component, and a lifter configured to actuate the locking device into and out of engagement with the locking structure, wherein the drive system component is selectively lockable by movement of the lifter.

Claims (26)

1. A medical device drive system comprising:

a locking structure;

a locking device sized and shaped to engage with the locking structure, the locking device coupled to a drive system component;

a lifter configured to actuate the locking device into and out of engagement with the locking structure;

a rotary input; and

a control knob coupled to the lifter,

wherein the drive system component is selectively lockable by movement of the lifter,

wherein the rotary input has an input feature that engages a portion of the lifter to pivot or translate the lifter and actuate the locking device, and

wherein turning the knob moves the lifter to actuate the locking device.

2. The medical device drive system of claim 1 , wherein the lifter is pivotably coupled to the locking structure, in a first state the lifter and locking device are pivoted toward the locking structure and the locking device is engaged with the locking structure to prevent rotational movement of the locking device relative to the locking structure, and in a second state the lifter and locking device are pivoted away from the locking structure and the locking device is not engaged with the locking structure.

3. The medical device drive system of claim 1 , wherein the lifter is slidably coupled to the locking structure, wherein translating the lifter with respect to the locking structure actuates the locking device into and out of engagement with the locking structure.

4. The medical device drive system of claim 1 , wherein the rotary input is configured to couple with a computerized control system.

5. The medical device drive system of claim 1 , further comprising a manual release, wherein the control knob is configured to control both the locking device and the manual release.

6. The medical device drive system of claim 1 , wherein the medical device drive system is configured to interface with an adaptor to operatively couple the drive system to a computerized control system.

7. The medical device drive system of claim 6 , wherein in a first state the medical device drive system is not coupled to the adaptor and the lifter and locking device are in an unlocked position, the litter and locking device being actuatable to a locked position, and in a second state the medical device drive system is coupled to the adaptor, the adapter is engaged with the lifter, and the lifter and locking device are in a locked position, the lifter and locking device being actuatable to an unlocked position.

8. The medical device drive system of claim 7 , wherein the lifter is pivotably coupled to the locking structure and in the second state the locking device is actuatable from the locked position to an unlocked position by manipulating an input that pivots the lifter.

9. The medical device drive system of claim 6 , further comprising one or more springs engaged between the locking structure and the lifter, the one or more springs being compressed when the drive system is interfaced with the adaptor.

10. The medical device drive system of claim 1 , wherein the locking device include a tapered structure that includes teeth that are sized and shaped to engage with corresponding teeth on a tapered recession in the locking structure.

11. The medical device drive system of claim 10 , wherein the teeth on the tapered structure and the corresponding teeth on the tapered recession are sized and shaped to prevent rotation of the tapered structure with respect to the tapered recession but to allow the tapered structure to both translate and pivot away from the tapered recession.

12. A medical device drive system comprising:

a locking structure;

a locking device sized coupled to a drive system component and shaped to engage with the locking structure; and

a lifter having an engagement end coupled to the locking device, the lifter being movable relative to the locking structure;

wherein in a first state the engagement end of the lifter is biased toward the locking structure and the locking device is engaged with the locking structure such that the drive system component is not drivable, and in a second state the engagement end of the lifter is biased away from the locking structure and the locking device is disengaged from the locking structure such that the drive system component is drivable, and

wherein the drive system component includes a steering control, the steering control being lockable by the locking device, the medical device drive system further comprising a manual release input, the manual release input being coupled to the lifter, wherein actuating the manual release locks the steering control.

13. The medical device drive system of claim 12 , wherein the lifter is pivotable with respect to the locking structure to move the lifter and locking device between the first state and the second state.
