Problems solved by technology

[0002] Traditional techniques generally use a manual trephine to remove the bone tissue of the articular process, which has low resection efficiency, poor safety, and low controllability, making it difficult to achieve the ideal resection effect
When the eccentric burr is used to remove bone tissue in minimally invasive surgery, due to the different conditions of the resection site, there are dynamic changes in the resection site, coupled with the precision requirements of the operation, it is necessary to fine-tune the surgical position of the eccentric burr during the process. The doctor's holding position will also change accordingly, and the eccentric burrs currently used for surgery do not have holding parts, and those with holding parts are not conducive to fine-tuning during the operation, affecting the accuracy and progress of the operation

Abstract

The invention discloses a grinding drill for bone grinding. The grinding drill comprises a grinding head (1) and a grinding handle connected with the grinding head. The grinding head (1) penetrates in a supporting rod (2) through the grinding handle. The center axis of the supporting rod (2) is parallel to the axis of the knife handle. The supporting rod (2) is provided with a limiting device. The position, on the supporting rod (2), of the limiting device axially moves and is locked under the effect of force. The supporting rod is arranged on the grinding handle and provided with the limiting device, so that use is convenient, and excision efficiency is high. The excision range can be controlled by moving the supporting rod, the operation precision and progress are improved, controllability is high, and therefore use safety is improved.
