A feed motor is fixed at the rear end of the shell, and a screw rod is connected to the front end of the feed motor. The screw rod is threadedly connected with the internal thread pipe. A trigger-type control switch is arranged on the lower side of the shell. The structure is simple, the energy consumption is low, the device is convenient to hold, and the device does not need to be positioned with other devices at the beginning of drilling, which brings convenience to medical work. CONTENT OF THE UTILITY MODEL

[0004] The utility model is aimed at the above problems, and provides a skull drilling equipment for craniotomy, which has good positioning effect and bone chip collecting function.

[0005] In order to achieve the above purpose of the utility model, the utility model adopts the following technical scheme. The utility model comprises a shell, and is characterized in that: a guide pipe is fixedly arranged on the shell, and an arc surface is arranged at the end of the guide pipe; a sliding seat is further arranged in the shell, and the sliding seat is connected with a feed motor at the end of the shell on one side; a driving motor is arranged on the other side of the sliding seat, a drill bit is arranged on the driving motor, and the drill bit corresponds to the center through hole of the arc surface; a dust suction port is arranged on the arc surface, and the dust suction port is connected with a dust suction device arranged on the guide pipe.

[0006] As a preferred scheme of the utility model, the arc surface has a gap for air flow after being attached to the skull, so that air flows into the dust suction port and the bone chips are sucked into the dust suction device.

[0007] As another preferred scheme of the utility model, a handle and a switch are arranged on the shell, the switch is connected with a controller on the shell, and the controller is electrically connected with the feed motor and the driving motor.

[0008] As a third preferred scheme of the utility model, a sliding rail is arranged in the shell, and the sliding seat is matched with the sliding rail.

[0009] As a fourth preferred embodiment of this utility model, the feed motor is provided with a screw, and the slide is provided with a threaded tube that cooperates with the screw.

[0010] As a fifth preferred embodiment of this utility model, the dust collection device is provided with a collection box connected to the dust collection port and a fan corresponding to the collection box.

[0011] The beneficial effects of this utility model are as follows: 1. This utility model sets an arc-shaped surface on the left side of the guide tube, which can cooperate with the skull to achieve positioning, improve the stability during drilling, reduce errors caused by equipment shaking, and thus improve the accuracy and safety of operation.

[0012] 2. This utility model sets a dust suction port on the guide tube and equips it with a fan and a collection box. At the same time, since the shape of the skull itself is not a standard arc surface, it naturally forms a gap when combined with the arc surface of this utility model, so that the bone fragments generated when the drill is working can be effectively collected, avoiding the bone fragments from scattering and affecting the surgical environment. At the same time, it reduces the cleaning burden on medical staff and improves surgical efficiency. Attached Figure Description
