[0024] The utility model provides a combined medical electric drill structure, which includes an electric drill main body 101, a control component, an electric drive component, a replaceable drill bit component, a modular battery component, a maintenance board 102 and an anti-slip handle 103. The control component includes a support board 104, a control module 105 and an operation screen 106. The electric drive component includes a first motor 107, a rotating shaft 108 and a second motor 109. The replaceable drill bit component includes a quick locking mechanism and a drill bit 110. The quick locking mechanism includes a rotating rod 111, a fixed sleeve 112 and a fixing bolt 113. The modular battery component includes a fixing plate 114, a power supply battery 115 and a charging interface 116. By the foregoing solution, the problem that the drill bit 110 used previously was fixedly installed and could not be disassembled, resulting in the inability to disassemble the drill bit 110 and replace it with the required drill bit 110 according to the surgical needs, is solved. It can be understood that the foregoing solution can be used in different surgical needs and scenarios where different types of drill bits 110 are required.

[0025] In this embodiment, by providing a replaceable drill bit component, the drill bit 110 can be disassembled and replaced with the required drill bit 110, so that the drill bit 110 can meet the different surgical needs of medical staff, and thus the applicable range of the combined medical electric drill structure is improved.

[0026] Among them, the control component, the electric drive component and the modular battery component are all arranged inside the electric drill main body 101. The control component is used to control the start and stop of the electric drive component. The electric drive component is used to drive the replaceable drill bit component to move. The drill bit 110 is connected to the electric drive component through the quick locking mechanism. The modular battery component is used to supply power for the operation of the control component and the electric drive component. The electric drill main body 101 is made of lightweight materials. By arranging the control component and the electric drive component inside the electric drill main body 101, the angle of the drill bit 110 can be intelligently controlled. By providing the modular battery component, it is convenient to replace the power supply battery 115 and charge the power supply battery 115, thus avoiding the situation of power shortage during the operation and improving the operation efficiency. By providing a replaceable drill bit component, the drill bit 110 can be disassembled and replaced with the required drill bit 110, so that the drill bit 110 can meet the different surgical needs of medical staff, and thus the applicable range of the combined medical electric drill structure is improved.

[0027] Secondly, the support plate 104 is arranged inside the electric drill body 101; the control module 105 is arranged on the upper surface of the support plate 104; the operation screen 106 is electrically connected to the control module 105 and is arranged outside the electric drill body 101. Since the operation screen 106 is electrically connected to the control module 105, when a medical staff operates the operation screen 106, the operation screen 106 will transmit an operation instruction to the control module 105, and then the control module 105 will generate a corresponding control instruction according to the operation instruction.

[0028] Thirdly, the first motor 107 is electrically connected to the control module 105 and is arranged inside the electric drill body 101; the rotating shaft 108 is connected to the output end of the first motor 107 and is located outside the first motor 107; the second motor 109 is electrically connected to the control module 105 and is arranged on the side of the rotating shaft 108 away from the first motor 107 and penetrates through the electric drill body 101. Through the control instruction generated by the control module 105, the start and stop of the first motor 107 or the second motor 109 can be controlled. The output end of the first motor 107 is connected to the rotating shaft 108 and drives the rotating shaft 108 to rotate along its own axis, so as to drive the second motor 109 to rotate along the axis of the rotating shaft 108.

[0029] Meanwhile, the rotating rod 111 is connected to the output end of the second motor 109 and is located on the lower surface of the second motor 109; the fixed sleeve 112 is fixedly arranged on the outside of the rotating rod 111; the fixing bolt 113 is detachably connected to the fixed sleeve 112, abuts against the drill bit 110 and penetrates through the fixed sleeve 112. The output end of the second motor 109 is connected to the rotating rod 111 and drives the rotating rod 111 to rotate along its own axis, so as to drive the fixed sleeve 112 to rotate along the axis of the rotating rod 111 on the outside of the rotating rod 111. The fixed sleeve 112 has a threaded hole, and the fixing bolt 113 is threadedly connected to the threaded hole of the fixed sleeve 112. The fixing bolt 113 can be tightened or loosened in the threaded hole of the fixed sleeve 112.

[0030] In addition, the fixed plate 114 is arranged inside the electric drill main body 101; the power supply battery 115 is electrically connected to the control module 105, is detachably connected to the fixed plate 114, and is located on the upper surface of the fixed plate 114; the charging interface 116 is arranged outside the power supply battery 115 and penetrates through the electric drill main body 101. The power supply battery 115 can be installed or removed on the fixed plate 114 to facilitate the replacement of the power supply battery 115. The power supply battery 115 is a battery that can be charged or discharged, and the charging interface 116 is a standard interface, so that the power supply battery 115 can be charged through the charging interface 116.

[0031] In addition, the maintenance board 102 is detachably connected to the electric drill main body 101 and is located on one side of the electric drill main body 101 close to the power supply battery 115. The electric drill main body 101 has a slot, and the maintenance board 102 is located in the slot of the electric drill main body 101 and can completely cover the slot of the electric drill main body 101. By setting the maintenance board 102, when the power supply battery 115 is replaced, the maintenance board 102 can be taken out of the slot of the electric drill main body 101, so that the internal space of the electric drill main body 101 is exposed, facilitating the replacement of the power supply battery 115 inside the electric drill main body 101.

[0032] Finally, the anti-slip handle 103 is arranged outside the electric drill main body 101. By holding the anti-slip handle 103, the drill bit 110 can be used to screw in, screw out and drill holes for screws. The outer side of the anti-slip handle 103 is evenly distributed with anti-slip lines. The anti-slip lines of the anti-slip handle 103 can increase the friction between the anti-slip handle 103 and the palm of the medical staff, so as to avoid the situation that the anti-slip handle 103 slips from the palm of the medical staff during the process of the medical staff holding the anti-slip handle 103.

[0033] When using the present utility model, when using the medical electric drill, select the corresponding drill bit 110 according to the surgical requirements. Then, align the drill bit 110 with the fixed sleeve 112 and push the drill bit 110 into the fixed sleeve 112. When the drill bit 110 can no longer be pushed, the drill bit 110 contacts the rotating rod 111. At this time, gradually tighten the fixing bolt 113 in the threaded hole of the fixed sleeve 112 until the fixing bolt 113 abuts against the outside of the drill bit 110, so that the drill bit 110 is limited and fixed in the fixed sleeve 112, realizing the installation of the drill bit 110. After installing the drill bit 110, connect the power supply battery 115 to an external power supply through the charging interface 116, so that the external power supply can charge the power supply battery 115 to ensure that there is no power shortage during the operation. Then, let the medical staff hold the anti-slip handle 103 with their palm. After that, operate the relevant buttons on the operation screen 106, so that the operation screen 106 transmits the operation instructions to the control module 105. As a result, the control module 105 will generate corresponding control instructions according to the operation instructions and control the start and stop of the first motor 107 or the second motor 109 through the control instructions. By starting the second motor 109, the power output from the output end of the second motor 109 drives the rotating rod 111 to rotate along its own axis, so as to drive the fixed sleeve 112 to rotate along the axis of the rotating rod 111 outside the rotating rod 111, and further drive the drill bit 110 to rotate along the axis of the rotating rod 111 outside the rotating rod 111, realizing the operations of screwing in, screwing out and drilling of the screw. By starting the first motor 107, the power output from the output end of the first motor 107 drives the rotating shaft 108 to rotate along its own axis, so as to drive the second motor 109 to rotate along the axis of the rotating shaft 108, and further drive the drill bit 110 to rotate along the axis of the rotating shaft 108 below the electric drill body 101, realizing the adjustment of the angle of the drill bit 110, so that the drill bit 110 can perform the operations of screwing in, screwing out and drilling of the screw at different angles. When the power supply battery 115 fails, take out the repair board 102 from the slot of the electric drill body 101 to expose the internal space of the electric drill body 101, so as to replace the power supply battery 115 in the electric drill body 101.

[0034] In summary, by providing the control component and the electric drive component within the electric drill body 101, intelligent control of the angle of the drill bit 110 can be achieved. By providing the modular battery component, it is convenient to replace the power supply battery 115 and charge the power supply battery 115, thereby avoiding power shortage during the operation and improving the efficiency of the operation. By providing the replaceable drill bit component, the drill bit 110 can be disassembled and replaced with the required drill bit 110, enabling the drill bit 110 to meet the different surgical needs of medical staff, and thus expanding the scope of application of the combined medical electric drill structure.
