Abstract
Abstract Insertion instruments and a main body assembly and a universal wing to be inserted are provided, along with methods of using these instruments for the insertion of the spinal implants in patients to relieve the symptoms of, for example, spinal stenosis, injuries, and degenerative diseases of the spine. The instruments are simply designed and can be disassembled, making cleaning and sterilization easy and convenient. The instruments are designed to engage with and disengage from spinal implants easily, and use of the instrument in spinal implant surgery can be carried out with minimal surgical intervention and does not require general anesthesia. The main body assembly and the universal wing are designed to conveniently be secured to the insertion instruments. In an alternative embodiment the instrument can be nested and at least one instrument can include a handle provided at an angle.

Claim 84
Dependent Claim
32 words
The insertion device of claim 57 , further comprising a spring attached to a second end of the insertion rod such that the spring biases the insertion rod toward the distal end.
Claim 85
Dependent Claim
114 words
An insertion device adapted for installing an implant having a rotatable spacer adjacent to spinous processes comprising: an elongated body having a longitudinal body axis; a proximal end having a handle; a distal end having an insertion tip including at least one alignment pin; a bore within the elongated body having an axis approximately parallel to the longitudinal body axis; and a retractable insertion rod within the bore adapted to be selectably extended from the distal end for locking the implant into place, the retractable insertion rod including a first end that has a locking pin and a spacer engagement pin adapted to limit the rotation of said spacer relative to said alignment pin.
Claim 86
Dependent Claim
