[0048] Please see Figures 1 to 5This embodiment provides a portable medical handheld high-speed drill, including a housing assembly 1, a drill bit assembly 2, and an adjustment assembly 3. The housing assembly 1 includes a grip part 11 and a drill body part 12, with the grip part 11 and the drill body part 12 arranged at a preset angle. The drill bit assembly 2 is embedded in the drill body part 12 and includes a drill bit 21 and a first drive unit. The first drive unit is drivenly connected to the drill bit 21, and one end of the drill bit 21 protrudes outward from the drill body part 12. The adjustment assembly 3 includes a second drive unit 31, an adjustment ring 32, a clutch assembly, and a transmission assembly 33. The second drive unit 31 is disposed in the housing assembly 1. The adjustment ring 32 is sleeved on the end of the drill bit 21 that protrudes from the drill body part 12. The adjustment ring 32 and the second drive unit 31 are drivenly connected through the transmission assembly 33. A clutch assembly is provided between the transmission assembly 33 and the adjustment ring 32. The adjustment ring 32 is drivenly connected to the drill bit 21. The second drive unit 31 is used to drive the adjustment ring 32 to rotate, so that the drill bit 21 reciprocates relative to the adjustment ring 32.

[0049] In this embodiment, the grip portion 11 in the housing assembly 1 is used for hand gripping during operation, and the preset angle formed between it and the drill body portion 12 conforms to ergonomic design, facilitating force application and precise control. The drill body portion 12 serves as the main load-bearing structure and has an internal mounting cavity.

[0050] Preferably, the first drive unit in the drill bit assembly 2 uses a motor in conjunction with a reduction gear mechanism to provide the main power for the rotary cutting of the drill bit 21; the second drive unit 31 of the adjusting assembly 3 is a micro motor, which transmits power to the adjusting ring 32 through the transmission group 33. Optionally, the transmission group 33 includes a gear train or a worm gear. The clutch group can be an electromagnetic clutch or a mechanical snap-fit ​​structure, used to selectively disconnect the power connection between the transmission group 33 and the adjusting ring 32. Preferably, the inner wall of the adjusting ring 32 is provided with a threaded structure that meshes with the external thread of the drill bit 21, and the axial displacement of the drill bit 21 is achieved by rotation.

[0051] This embodiment integrates the adjustment function of drill bit 21. During operation, the second drive unit 31 drives the transmission group 33, and the clutch group controls the power transmission to the adjustment ring 32. When the adjustment ring 32 rotates, it can drive the drill bit 21 to move axially through the threaded pair to achieve depth adjustment, eliminating the dependence on external adjustment tools and simplifying the operation process. This embodiment can directly and quickly adjust the position of drill bit 21 through the built-in drive mechanism (i.e., adjustment component 3), avoiding the time loss of searching for external adjustment rods; the integrated design reduces the number of instruments and reduces the complexity of intraoperative instrument management; the clutch group ensures independent control between the main cutting and adjustment functions, preventing misoperation from interfering with the surgical process; the overall structure is compact, maintaining portability while improving operational efficiency and reliability.

[0052] In some embodiments, the drill bit 21 protrudes from the drill body 12 and has a first inclined surface in the circumferential direction, and the adjusting ring 32 has a second inclined surface on its inner side, with the first inclined surface and the second inclined surface fitting together.

[0053] In this embodiment, the first inclined surface protruding from the drill body 12 and arranged circumferentially cooperates with the second inclined surface arranged inside the adjusting ring 32. When the second driving unit 31 drives the adjusting ring 32 to rotate, the interaction between the first inclined surface and the second inclined surface converts the rotational motion into the axial displacement of the drill bit 21.

[0054] This embodiment achieves precise positioning and smooth adjustment of the drill bit 21 through the cooperation structure of the first inclined surface and the second inclined surface, enhancing the operating feel; at the same time, it simplifies the transmission structure, making the overall device more compact and reliable, and facilitating quick adjustment of the drill bit 21 depth when operating with one hand, significantly improving adjustment efficiency and operational convenience.

[0055] In some embodiments, the drill bit 21 protrudes from the drill body portion 12 and is provided with a first adjusting thread in the circumferential direction. The first adjusting thread is disposed between the first inclined surface and the drill body portion 12. The inner side of the adjusting ring 32 is provided with a second adjusting thread, which is adapted to the first adjusting thread.

[0056] In this embodiment, by providing a first adjusting thread protruding from the drill body 12 in the circumferential direction of the drill bit 21 and a second adjusting thread adapted thereto on the inner side of the adjusting ring 32, when the second driving unit 31 drives the adjusting ring 32 to rotate, the meshing action of the first adjusting thread and the second adjusting thread accurately converts the rotational motion into the axial displacement of the drill bit 21.

[0057] This embodiment further improves the accuracy and stability of drill bit 21 position adjustment through the cooperation structure of the first adjustment thread and the second adjustment thread, while enhancing transmission efficiency; the meshing of the first adjustment thread and the second adjustment thread makes the adjustment process more stable and controllable, effectively avoiding slippage during the adjustment process, and providing a more reliable depth adjustment guarantee for surgical operations.

[0058] In some embodiments, the drill bit 21 has a plurality of sub-drill bodies 211 protruding from the end of the drill body 12. The sub-drill bodies 211 are assembled to form the drill bit 21, and there is a gap between two adjacent sub-drill bodies 211.

[0059] In this embodiment, by providing multiple sub-drill bodies 211 at the end of the drill bit 21 that protrudes from the drill body 12, when the adjustment component 3 is working, the second drive unit 31 drives the adjustment ring 32 to rotate through the transmission group 33. The rotation of the adjustment ring 32 causes the multiple sub-drill bodies 211 to generate radial displacement within the gap range, thereby realizing the adjustment of the overall diameter of the drill bit 21.

[0060] This embodiment utilizes the adjustable structure of the drill body 211 to enable a single drill bit 21 to adapt to drilling requirements of different diameters, significantly improving the applicability of surgical instruments. Through mechanical linkage, stepless adjustment of the diameter is achieved, ensuring adjustment accuracy while simplifying the operation process, providing a more flexible and efficient drilling solution for clinical surgery.

[0061] In some embodiments, the transmission assembly 33 includes a first bevel gear 331, a second bevel gear 332, a first transmission shaft 333, a third bevel gear 334, and a fourth bevel gear 335. The first bevel gear 331 is connected to the output end of the second drive unit 31 via a keyway; the second bevel gear 332 is meshed with the first bevel gear 331; the first transmission shaft 333 is connected to the second bevel gear 332; the third bevel gear 334 is sleeved on the first transmission shaft 333, and the third bevel gear 334 is disposed opposite to the second bevel gear 332; the fourth bevel gear 335 is disposed on the adjusting ring 32.

[0062] In this embodiment, the first bevel gear 331 of the transmission assembly 33 receives the power output from the second drive unit 31, and its keyway connection ensures the reliability of the transmission. The second bevel gear 332 meshes with the first bevel gear 331 to achieve the first change in the direction of power. The first transmission shaft 333, as an intermediate transmission component, transmits power to the third bevel gear 334. The third bevel gear 334 meshes with the fourth bevel gear 335 to achieve the second change in the direction of power, ultimately driving the adjusting ring 32 to rotate. The fourth bevel gear 335 is fixed on the adjusting ring 32, directly transmitting the rotational motion to the adjusting ring 32. Preferably, the first bevel gear 331, the second bevel gear 332, the third bevel gear 334, and the fourth bevel gear 335 are all made of high-strength alloy steel to ensure transmission accuracy and durability.

[0063] This embodiment achieves power transmission and direction conversion through multi-stage bevel gear transmission. When the second drive unit 31 is activated, power is sequentially transmitted to the adjusting ring 32 via the first bevel gear 331, the second bevel gear 332, the first drive shaft 333, the third bevel gear 334, and the fourth bevel gear 335. The bevel gear transmission structure of this embodiment is compact and has high transmission efficiency, making it particularly suitable for power transmission within limited space. The multi-stage transmission of the first bevel gear 331, the second bevel gear 332, the first drive shaft 333, the third bevel gear 334, and the fourth bevel gear 335 allows for flexible adjustment of the transmission ratio to meet the adjustment requirements under different working conditions. The keyway connection ensures the reliability of power transmission and avoids slippage. The overall structural layout is reasonable, minimizing the equipment size and improving operational convenience while ensuring functionality.

[0064] In some embodiments, the clutch assembly includes an elastic element and a button. The elastic element is disposed between the drill body portion 12 and the first drive shaft 333; the button is embedded in the drill body portion 12 and is also connected to the elastic element.

[0065] In this embodiment, the elastic element of the clutch assembly can be a stainless steel spring, which is disposed between the drill body 12 and the first transmission shaft 333 to provide a reset force; the button is embedded in the surface of the drill body 12 and connected to the elastic element for manual control of the clutch state. When the button is pressed, it overcomes the resistance of the elastic element and drives the first transmission shaft 333 to move axially, realizing the engagement and disengagement of the bevel gear set, and the transmission state can be switched through a simple mechanical operation.

[0066] This embodiment achieves transmission clutch control through the cooperation of a button and an elastic element. Pressing the button drives the elastic element, causing the first transmission shaft 333 to move downwards, further engaging the first bevel gear 331 with the second bevel gear 332 and the third bevel gear 334 with the fourth bevel gear 335. At this time, the power of the second drive unit 31 can be transmitted to the adjusting ring 32. Controlling the rotation of the second drive unit 31 automatically adjusts the number of rotations of the adjusting ring 32, realizing automatic axial adjustment of the drill bit 21. Releasing the button causes the elastic element to reset the transmission shaft, disengaging the gear set of the first bevel gear 331 and the second bevel gear 332, and the third bevel gear 334 and the fourth bevel gear 335. This embodiment is simple and intuitive to operate, achieving rapid engagement and disengagement of the transmission set 33 with a single button; the elastic element ensures smooth and reliable clutch action, avoiding impact damage to the gears; the overall structure is compact, without increasing additional operational complexity, improving the ease of use and reliability of the equipment while ensuring functionality, and providing a more convenient adjustment and control method for surgical operations.

[0067] In some embodiments, the portable medical handheld high-speed drill further includes a control unit and a display unit. The control unit is electrically connected to the first drive unit and the second drive unit 31. The display unit is electrically connected to the control unit and is embedded on the outside of the grip portion 11 and / or the drill body portion 12.

[0068] In this embodiment, by adding a control unit and a display unit, when the control unit issues a command, the control unit synchronously coordinates the working states of the first drive unit and the second drive unit 31, and feeds back the operating parameters to the display unit in real time.

[0069] This embodiment achieves precise digital control of the drill bit's rotation speed and feed depth, significantly improving the accuracy of surgical operations; the display unit intuitively presents key parameters, allowing the surgeon to monitor the equipment status in real time; the dual-path coordinated control of the control unit ensures the synchronization of cutting and adjustment actions, avoiding misoperation; the overall design conforms to the trend of intelligent medical equipment in modern times, greatly improving operational convenience and safety while maintaining portability.

[0070] In some embodiments, the portable medical handheld high-speed drill also includes an adjustment button group, which is electrically connected to the control unit. The adjustment button group is located on the outside of the drill body 12 and includes multiple adjustment buttons, each of which is configured to perform a different function.

[0071] In this embodiment, by setting an adjustment button group on the outside of the drill body 12 and electrically connecting it to the control unit, when different adjustment buttons are pressed, the control unit controls the first drive unit and the second drive unit 31 to perform corresponding functions according to a preset program.

[0072] The button-based operation interface of this embodiment is intuitive and convenient, allowing for quick switching between different working modes. The independent configuration of function buttons avoids confusion in parameter settings and improves operational accuracy. The rationally arranged button group facilitates one-handed operation, which helps improve surgical efficiency and provides a more intelligent control method for clinical operations.

[0073] In some embodiments, the display unit is a touch screen.

[0074] In this embodiment, by using a touch screen as the display unit, the operation can be performed directly on the screen. The control unit precisely adjusts the working parameters of the first driving unit and the second driving unit 31 according to the touch command, which simplifies the operation process, improves the intuitiveness and convenience of the operation, and makes the surgical control more precise and efficient.

[0075] In some embodiments, the portable medical handheld high-speed drill also includes an indicator light, which is disposed adjacent to the display unit and electrically connected to the control unit. The indicator light is configured to display three colors: red, yellow, and green.

[0076] In this embodiment, by adding multi-color indicator lights, the control unit drives the indicator lights to switch the corresponding colors when the device is in different working states, forming a dual prompt with the display unit, which significantly improves the intuitiveness of device status identification, so as to quickly judge the device's operating status and ensure the safety and reliability of surgical operations.

[0077] By adopting the above technical solutions, this utility model differs from the prior art and has the following beneficial effects: Through the coordinated cooperation of the housing assembly 1, the drill bit assembly 2, and the adjustment assembly 3, a high degree of integration and intelligence of the medical handheld high-speed drill is achieved. The grip part 11 and the drill body part 12 are set at a preset angle that conforms to ergonomics, improving operating comfort. The first drive unit and the second drive unit 31 respectively control the rotation and axial adjustment of the drill bit 21, enabling the device to have both cutting and precise positioning functions. The adjustment assembly 3, through the mating structure of the first and second inclined surfaces and the first and second adjusting threads, achieves smooth and precise depth adjustment of the drill bit 21. The design of the split drill body 211 allows a single drill bit 21 to adapt to different hole diameter requirements. The transmission group 33, through multi-stage bevel gear transmission of the first bevel gear 331, the second bevel gear 332, the first transmission shaft 333, the third bevel gear 334, and the fourth bevel gear 335, ensures reliable power transmission. The combination of buttons and elastic elements in the clutch group simplifies the operation process. The cooperation between the control unit and the display unit enables digital parameter management. The touch screen and indicator lights further optimize the human-computer interaction experience. The overall structure of the above technical solution is compact and reasonable, realizing integrated operation of the drill bit 21 adjustment function without the need for external adjustment tools, significantly improving surgical efficiency, operational convenience, and safety while maintaining portability.
