Anti-skid surgical instrument for use in preparing holes in bone tissue
First Claim
1. An anti-skid surgical instrument having an elongate structure comprising:
- a mill head at the end of the elongate structure for removing bone tissue with reduced skidding of the surgical instrument upon contact of the anti-ski surgical instrument with the bone tissue, wherein the mill head has a flat head substantially perpendicular to a longitudinal axis of the elongate structure, and one or more side-cutting flutes about the longitudinal axis of the elongate structure for cutting into bone tissue;
a shank for connection to a drill; and
a shaft between the mill head and the shank, the shaft having one or more drill flutes for evacuating removed bone tissuewherein the anti-skid surgical instrument is coupled to an end effector of a robotic armwherein the end effector is configured to hold and/or restrict movement of the anti-skid surgical instrumentwherein the anti-skid surgical instrument includes an integrated tool support that engages with the end effector to provide accurate guidance of the anti-skid surgical instrument.

Abstract
Described herein is an anti-skid surgical instrument for use in preparing holes in bone tissue. The disclosed surgical instrument provides the ability to prepare a precise hole in bone tissue during surgery (e.g., spinal surgeries and pedicle screw placement, intramedullary screw placement). The disclosed surgical instrument accomplishes precise hole placement regardless of whether the angle between the drill axis and surface of the bone tissue is perpendicular. The disclosed technology includes a flat drilling surface which is perpendicular to the surface of the body of the surgical instrument. This reduces the likelihood of the surgical instrument skidding on the surface of the bone tissue and thereby increases the precision of the hole.
