Embodiment Construction

[0020] Such as Figure 1~Figure 4 As shown, the articular process bone drilling device provided by the present invention which can control the bone drilling depth includes a positioning sleeve and a bone grinding drill.

[0021] The bone grinding drill comprises a cylindrical straight shank drill rod 2, an operating handle 6 is connected to the upper end of the drill rod 2, and a drill bit is arranged at the lower end of the drill rod 2. A section of threaded segment 7 is arranged on the drill rod 2 adjacent to the operating handle 6 . The major diameter of the threaded segment 7 is larger than the diameter of the drill rod 2 , and a stop nut 8 is threadedly connected to the threaded segment 7 .

[0022] The positioning sleeve includes a positioning sleeve body 1. The positioning sleeve body 1 is a cylindrical rod structure. On the positioning sleeve body 1, there is an axially penetrated cylindrical channel 9 for inserting the bone grinding drill rod 2. , the axis of the chan...

Abstract

The invention provides a zygopophysis bone drilling device capable controlling bone drilling depth. The zygopophysis bone drilling device structurally comprises a positioning sleeve and a bone grinding drill, wherein the bone grinding drill is characterized in that an operating handle is connected with the upper end of a cylindrical straight-shank drill rod; a drill bit is arranged at the lower end of the drill rod; a section of threaded section is arranged on the drill rod adjacent to the operating handle; the major diameter of the threaded section is larger than the diameter of the drill rod; a limiting nut is in threaded connection with the threaded section; the positioning sleeve is characterized in that a cylindrical channel axially penetrating through and used for allowing a drill rod of the bone grinding drill to be inserted in a penetrating manner is formed in a sleeve body; a flaring section which can accommodate the threaded section of the drill rod is arranged at the upper end of the channel; and a wide-mouth spoon groove or a wide-mouth bracket which can straddle the zygopophysis is arranged at the lower end of the sleeve body. By adopting the zygopophysis bone drilling device provided by the invention, the superior articular process can be positioned accurately, and the bone grinding depth can be controlled, so that on the premise of safety and stability, bone substances blocking in the direction of an operative approach can be accurately eliminated through grinding and an accurate and wide implantation space is provided for the working sleeve.

Description

technical field [0001] The invention relates to an orthopedic medical device, in particular to an articular process bone drill capable of controlling the depth of bone drilling. Background technique [0002] Lumbar intervertebral disc herniation is a common and frequently-occurring disease in spinal orthopedics. It is due to the degeneration of the intervertebral disc, the rupture of the annulus fibrosus, and the protrusion of the nucleus pulposus to the spinal canal, which stimulates and compresses nerve roots, blood vessels or spinal cord. Symptoms such as numbness. Patients often suffer from severe pain and cannot walk, which seriously affects their life. Traditional surgical treatment involves large trauma, heavy bleeding, slow postoperative recovery, and there are adverse reactions such as long-term postoperative waist discomfort and high recurrence rate. With the popularization of minimally invasive concept, intervertebral foramina mirror technology came into being. ...
