Methods and devices for accessing and retracting a capsule of a joint
View Patent ↗Devices and methods are disclosed herein for accessing the hip joint. A first device can be securely attached to the capsule of a joint. The first device can tent the capsule to increase the volume of the peripheral compartment. A second device can be biased against the first device to pierce the tented capsule and create a portal. Devices and methods are also disclosed herein for distending the capsule of a joint. A distention device may access a portal established within the capsule. The distention device can expand the capsule by applying an expansive force within the peripheral compartment. The distention device can maintain distention of the peripheral compartment while other devices access the joint.
1. A method of retracting a capsule of a joint and maintaining the retraction of the capsule of the joint, the method comprising:
providing a length of suture;
providing a cannula having a distal end for positioning in the joint and a proximal end comprising a projection for securing a length of suture;
passing the length of suture through the capsule of the joint so that two free ends of suture extend through the cannula;
pulling the length of suture proximally so as to retract the capsule of the joint; and
securing the length of suture around the projection so as to maintain the retraction of the capsule of the joint.
2. The method of claim 1 further comprising:
forming a cut in the capsule;
providing a second length of suture and a second cannula having a distal end for positioning in the joint and a proximal end comprising a projection for securing a length of suture;
passing the second length of suture through the second cannula and into the capsule of the joint so that two free ends of suture extend from the second cut side of the capsule;
pulling the second length of suture proximally so as to retract the second cut side of the capsule of the joint; and
securing the second length of suture around the projection so as to maintain the retraction of the joint.
3. The method of claim 1 wherein the projection comprises a post for receiving a length of suture.
4. The method of claim 3 wherein the post comprises a slot for receiving a length of suture.
5. The method of claim 1 wherein the projection comprises a clamp for receiving a length of suture.
