Description

Technical Field

[0001] The utility model relates to the technical field of drill grinding, in particular to a direction-changing drill grinding handle and a drill grinding assembly. Background Art

[0002] At present, spinal surgery is extremely risky. When removing bone spurs that compress the spinal cord or nerve roots in front and behind the spinal cord, a high-speed electric drill is often and must be used. The current drill has only one angle. When removing bone spurs in different directions and positions, the surgeon needs to change different body positions and hand directions, which brings trouble to the surgeon.

[0003] Chinese utility model patent publication number CN205493937U discloses a multi-angle drill grinder comprising a handle. The handle has a horizontally rotatable rotating rod at its upper end, and a vertically rotatable swing rod at its end. A first motor is housed within the handle, and the lower end of the rotating rod extends into the handle and is connected to the first motor, driving the rotating rod for horizontal rotation. The rotating rod has a semicircular upper end and a longitudinal groove. The swing rod has a protrusion at its rear end that fits within the groove and fits within the groove. A rotating shaft is mounted on the protrusion, and both ends of the shaft are movably connected to the sidewalls of the groove, enabling the swing rod to rotate vertically about the shaft. A second motor is housed within the rotating rod and connected to the shaft, driving the shaft to rotate the swing rod. The swing rod is a hollow, conical shape, housing a third motor. A drill bit inserted within the swing rod is connected to the third motor, driving the drill bit to rotate at high speed. The drill bit includes a drill rod and a grinding ball mounted at one end of the drill rod. The grinding ball is provided with a cutting edge that generates a cutting force when rotated at high speed, thereby grinding bone spurs and the like. The handle is provided with a control box containing a control switch that controls the operation of the first, second, and third motors, respectively. The first and second motors are stepper motors that can be started or stopped instantly, driving the rotating rod to rotate horizontally or the swing rod to rotate vertically through a certain angle, thereby flexibly changing the direction or angle of the grinding ball. This avoids the inconvenience of the surgeon previously having to change position, ensuring a smooth surgical procedure.

[0004] The above patents have the following deficiencies:

[0005] The handle itself does not have a direction-changing function, and the direction-changing function is mainly achieved by the hinge between the handle and the swing rod, which makes the rotation of the rotating rod unstable. Since the handle and the swing rod are hinged, when the angle between the handle and the swing rod is adjusted, the handle and the swing rod are relatively unstable, which causes the swing rod to shake during the drilling operation and affects the drilling effect. Utility Model Content

[0006] In view of the problems existing in the existing direction-changing drill grinding handle and drill grinding assembly, the present utility model is proposed.

[0007] Therefore, the purpose of the present invention is to provide a direction-changing drill grinding handle and a drill grinding assembly, which solves the problem that the handle itself does not have a direction-changing function, and the direction-changing function is mainly achieved by hinged connection between the handle and the swing rod, which makes the rotation of the rotating rod unstable; since the handle and the swing rod are hinged, when the angle between the handle and the swing rod is adjusted, the handle and the swing rod are relatively unstable, which causes the swing rod to shake during the drilling operation and affects the drilling effect.

[0008] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0009] A direction-changing drill handle comprises a handle grip, the top end of which is hinged to a first support rod, the end of which is provided with a docking seat, and an electric telescopic rod is hinged between the docking seat and the handle grip.
