The grinding drill is one of the common tools in the operation, is used for grinding vertebral plate, articular process and hyperosteogeny, and can greatly improve the operation efficiency.
However, the following problems exist with conventional abrasive drills during the BEss surgical application:
1. the abrasion drill can be wound and damage surrounding soft tissues and even damage nerves when entering an operation area and rotating at a high speed.
2. Bone fragments abraded by a traditional abrasive drill can be washed out of an incision or remained in a body by saline water, cannot be effectively utilized, and can become iatrogenic waste to cause adverse reaction in the body.
3. The nerve roots are located in the deep operation area, auxiliary treatment medicines are required to be injected around the nerve roots in the operation, the abrasive drill needs to be taken out and then injected, the operation is complicated, the time is wasted, the medicines cannot easily reach the deep target area, and surrounding tissues can be damaged during injection.

Firstly, the second independent structure 2 is sleeved into the grinding drill, then the first independent structure 1 is sleeved, and the first independent structure 1 and the second independent structure 2 can be tightly and firmly connected into a whole by reversely rotating on the grinding drill rod 4-2. Then the abrasive drill sleeved with the safety sleeve can be placed into an operation channel of a BEss instrument, and the ventral side is a working side of the abrasive drill bit 4-1 and can be used for removing bone; the back side is a protection side of the abrasive drilling bit, which can protect nerves and can assist in separating and shielding surrounding tissues.
As shown in fig. 2 and 3, the first independent structure 1 provided by the present invention is an integral structure, and the first independent structure 1 is divided into three parts, namely, a cylinder head part 1-1, a cylinder body part 1-2 and a connecting part 1-3.
The head of the ring cylinder is designed to be an arc inclined plane, and the edge of the head is a passivated fillet surface, so that peripheral tissues such as nerves, muscles and the like can be prevented from being damaged.
After the abrasive drill is sleeved, the abrasive drill bit is positioned in the center of the arc-shaped inclined plane at the tail end of the head of the annular cylinder, the ventral tail end of the head of the annular cylinder is shorter than the abrasive drill bit, and the dorsal tail end of the head of the annular cylinder is longer than the abrasive drill bit.
During surgery, the burr bit may abrade bone in the ventral region, while the dorsal sleeve may act as a barrier to protect nerves and other soft tissue. The ring barrel body is designed as a hollow cylinder, the axial direction of the abrasive drilling rod is positioned in the center of the ring barrel body, and the outer wall of the ring barrel body ensures that the abrasive drilling rod cannot wind surrounding soft tissues in the high-speed rotation process. The diameter of the connecting part is larger than that of the annular cylinder part, the outer part is polygonal, the inner part is cylindrical, the upper part is connected with the annular cylinder part, and the lower part is connected with the second independent structure 2 through the inner cylindrical structure.
