Surgical tools for treatment of spinal stenosis
First Claim
1. A method of capturing a pullwire using a pullwire handle device configured to secure to a distal end of a pullwire, the method comprising:
- inserting the distal end of a pullwire into the pullwire handle device;
advancing the pullwire further into the pullwire handle device while the distal end of the pullwire is contained within the pullwire handle device;
locking the pullwire within the pullwire handle device;
coupling a device to a proximal region of the pullwire; and
pulling on the pullwire handle device to advance the device through a spinal foramen.

Abstract
Described herein are pullwire handle devices for securing to a tissue-penetrating pullwire. In some embodiments, the device includes a handle body, a pullwire lock configured to removably lock the pullwire handle device onto a pullwire within the handle body, and a tip containment element configured to retain the distal tip of the pullwire. In some embodiments, the handle body further comprises a storage chamber configured to store a distal portion of the pullwire. Also described herein are methods for capturing a pullwire using a pullwire handle device. In some embodiments, the method includes the steps of inserting the distal end of a pullwire into the pullwire handle device, advancing the pullwire further into the pullwire handle device while the distal portion of the pullwire is contained within the pullwire handle device, and locking the distal portion of the pullwire within the pullwire handle device.

11. A method of capturing a pullwire using a pullwire handle device configured to secure to the distal end of a pullwire, the method comprising:
-
inserting the distal end of the pullwire into the pullwire handle device; moving a cam surface of a locking mechanism of the pullwire handle device such that the cam surface applies a force to a clamp plate and the clamp plate applies a force to the pullwire, wherein moving the cam surface comprises rotating the cam surface against the clamp plate and moves the clamp plate toward the pullwire; and moving the clamp plate within the pullwire handle device such that the cam surface applies an increased force to the clamp plate and the clamp plate secures the pullwire. - View Dependent Claims (12, 13, 14, 15, 16)
