Abstract

Various devices, systems, and methods for knotless suture anchors are provided. In general, a guide device can be cannulated and can be configured to slidably receive therein an inserter tool configured to deliver a suture anchor into a hole formed in bone, such as with a drill advanced through the guide device. The guide device with the inserter tool therein can be configured to be held as a unit by one hand of a person, e.g., a surgeon or other medical personnel.

First claim

What is claimed is:

1. A surgical system, comprising:
an anchor;
a first surgical device having an inner lumen extending therethrough and having a first engagement feature thereon; and
a second surgical device configured to deliver the anchor into bone, the second surgical device being configured to be advanced distally in the inner lumen, the second surgical device having a second engagement feature thereon configured to engage the first engagement feature, engagement of the first and second engagement features being configured to fix a position of the second surgical device relative to the first surgical device such that, with the second surgical device located in the inner lumen, the first and second surgical devices are configured to be held as a unit without the second surgical device moving in the inner lumen;
wherein, with the first and second engagement features engaged, the second surgical device is configured to be in the fixed position with the second surgical device at any selected axial position along the first surgical device;
wherein the second surgical device is configured to be advanced distally in the inner lumen with the anchor releasably coupled to a distal end of the second surgical device; and
the first engagement feature is configured to cooperate with the second engagement feature to limit removal of the second surgical device from the inner lumen to a single motion.

2. The system of claim 1 , wherein the second surgical device is configured to advance proximally in the inner lumen of the first surgical device; and
the proximal advancement of the second surgical device is configured to automatically cause the second surgical device to be decoupled from the anchor.

3. The system of claim 1 , wherein the engagement of the first and second engagement features is configured to limit the second surgical device to advancing distally in the inner lumen in a first type of motion.

4. The system of claim 3 , wherein the first type of motion is translational motion such that second surgical device is configured to advance distally in the inner lumen of the first surgical device by translating along a longitudinal axis of the second surgical device.

5. The system of claim 4 , wherein the second surgical device is configured to advance proximally in the inner lumen of the first surgical device by rotating about the longitudinal axis of the second surgical device.

6. The system of claim 3 , wherein the first type of motion is rotational motion such that the second surgical device is configured to advance distally in the inner lumen of the first surgical device by rotating about a longitudinal axis of the second surgical device.

7. The system of claim 6 , wherein the second surgical device is configured to advance proximally in the inner lumen of the first surgical device by sliding longitudinally.

8. The system of claim 1 , wherein one of the first and second engagement features is a thread, and the other of the first and second engagement features is a tooth configured to threadably engage the thread.

9. The system of claim 1 , further comprising a drill configured to drill a hole in the bone, the drill being configured to be advanced distally in the inner lumen of the first surgical device and then removed therefrom prior to the second surgical device being advanced distally in the inner lumen.

10. The system of claim 1 , further comprising
a suture configured to be coupled to the anchor and to a soft tissue.

11. The system of claim 1 , wherein the first and second surgical devices are configured to be held as the unit by a single hand of a user.

12. The system of claim 1 , wherein the first and second surgical devices are configured to be held as the unit by a single surgical robot arm.

13. A surgical system, comprising:
an anchor configured to be implanted in bone;
a first surgical device having an inner lumen; and
a second surgical device configured to be advanced distally through the inner lumen of the first surgical device such that a distal end of the second surgical device having the anchor engaged therewith exits the inner lumen and enters bone;
wherein, after the distal advancement of the second surgical device, a single motion of the second surgical device is configured to remove the second surgical device from the inner lumen of the first surgical device and to automatically disengage the second surgical device from the anchor; and
wherein an inner structure of the first surgical device is configured to cooperate with an external structure of the second surgical device to limit removal of the second surgical device from the inner lumen of the first surgical device to the single motion.

14. The system of claim 13 , wherein the second surgical device is configured to be advanced distally through the inner lumen of the first surgical device in only a first type of motion;
the single motion of the second surgical device is a second, different type of motion; and
one of the first and second types of motion is translational motion, and the other of the first and second types of motion is rotational motion.

15. The system of claim 13 , further comprising a drill configured to drill a hole in the bone, the drill being configured to be advanced distally through the inner lumen of the first surgical device and then removed therefrom prior to the second surgical device being advanced distally through the inner lumen;
wherein the anchor is configured to be in the hole when the second surgical device is automatically disengaged from the anchor.

16. A surgical method, comprising:
advancing a second surgical device distally in an inner lumen of a first surgical device such that a first engagement feature of the first surgical device becomes engaged with a second engagement feature of the second surgical device, the engagement of the first and second engagement features fixing a position of the second surgical device relative to the first surgical device such that the first and second surgical devices are configured to be held as a unit without the second surgical device moving in the inner lumen; and
after advancing the second surgical device distally in the inner lumen of the first surgical device, advancing, in a single motion, the second surgical device proximally in the inner lumen of the first surgical device such that the second surgical device is removed from the inner lumen of the first surgical device and the second surgical device is automatically decoupled from an anchor releasably coupled thereto;
wherein the first engagement feature cooperates with the second engagement feature to limit removal of the second surgical device from the inner lumen of the first surgical device to the single motion.

17. The method of claim 16 , wherein the engagement of the first and second engagement features limits the second surgical device to advancing distally in the inner lumen in a first type of motion and limits the second surgical device to advancing proximally in the inner lumen in a second, different type of motion; and
one of the first and second types of motion is translational motion, and the other of the first and second types of motion is rotational motion.

18. The method of claim 16 , wherein, with the first and second engagement features engaged, the second surgical device is configured to be in the fixed position with the second surgical device at any selected axial position along the first surgical device.

19. The method of claim 16 , wherein the first and second surgical devices are held as the unit
