Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and in particular relates to a bone drill power handle that is easy to observe. Background Technology
[0002] In surgical procedures, bone drill power devices are often used to drill holes in the bone. A bone drill power device consists of a drill bit and a power handle. The drill bit is mounted at the front end of the power handle, and the power supplied by the handle drives the drill bit to rotate, thus working on the bone tissue.
[0003] Currently, when using bone drill power devices, doctors generally rely on their tactile experience or visual estimation to determine whether the drilling depth meets the surgical requirements. Although some devices use photoelectric components, such as rangefinders or distance sensors, to automatically measure the drilling distance, these typically involve adding a fixing device to the outside of the handle to secure the photoelectric component. For example, the solutions disclosed in publication numbers CN109394298A and CN213606673U both attach the fixing distance measuring component to the front or top of the handle. This can easily obstruct the doctor's view during surgery, increasing the surgical risk. Utility Model Content

[0031] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.
[0032] It should be understood that this invention can be embodied in various forms and should not be construed as being limited to the embodiments set forth herein. Rather, providing these embodiments will make the disclosure thorough and complete, and will fully convey the scope of this invention to those skilled in the art. In the drawings, the same reference numerals denote the same components throughout.
[0033] The specific structure of the easily observable bone drill power handle in this utility model is described in conjunction with [reference needed]. Figures 1 to 5 The easily observable bone drill power handle is used to connect to the drill bit and provide power to it. The power handle includes:
[0034] Handle body 11;
[0035] Handle 18 is connected to the bottom of the handle 11, and the center line of the handle 18 is arranged at an angle to the axis of the handle 11.
[0036] A ranging module, which is used to acquire the drilling depth data of the drill bit in real time;
[0037] The chamber 20 is disposed at one end of the handle 11 away from the drilling direction of the drill bit. The chamber 20 has a receiving cavity in which the ranging module is housed. The bottom part of the chamber 20 is embedded in the handle 11, and the top of the chamber 20 is higher than the upper surface of the handle 11.
[0038] The handheld component 18 and the handle component 11 can be a single integrated structure, and the chamber 20 can be a single integrated structure with the handle component 11, or it can be detachably connected to the handle component 11. The chamber 20 is located at the upper end of the handle component 11 and is away from the drilling direction of the drill bit, that is, facing the direction of the doctor when using the handle.
[0039] The ranging module can use a ranging sensor 30 to collect drilling depth data. Specifically, the ranging sensor 30 is used to generate a ranging signal, and the cutting depth data of the drill bit can be obtained in real time based on the ranging signal.
[0040] The ranging sensor 30 can be a laser displacement sensor. The ranging principle of a laser displacement sensor is as follows: a laser beam is obliquely incident on the surface of the object being measured at a fixed angle (e.g., 30°), forming a diffuse reflection spot; the reflected light is focused onto the detector array through a receiving lens, and the position of the spot changes linearly with the displacement of the object; the displacement is calculated using geometric trigonometric relationships (formula: displacement = baseline distance × tan(receiving angle)). In practical applications, laser displacement sensors typically include a laser emitter, an optical system, a photodetector, and a signal processing circuit; some models also support multiple output modes (e.g., switch input, RS485 communication) and intelligent detection functions (e.g., two-point teach mode).
[0041] Additionally, the handheld component 18 is designed for the surgeon to hold the powered handle during surgery. The handheld component 18 houses the main controller for the bone drill powered handle, controlling the reception and processing of cutting depth data from the ranging module and providing feedback. The handle body 11 facilitates the installation of other structures, such as… Figure 4 As shown, the shank body 11 includes a shank housing 12 and an output sleeve 17. The output sleeve 17 is detachably connected to the shank housing 12. A drive module 13, a reduction module 14, and a drill bit identification module are housed within the sleeve. The drive module 13 is electrically connected to and controlled by a controller. The drive module 13 uses a drive motor and provides output power to the power handle. A drill bit clamping member 16 is located at the front end of the output sleeve 17, used to clamp the drill bit. The drive module 13, reduction module 14, and drill bit identification module can be pre-installed on the output sleeve 17 before it is assembled into the shank housing 12. This makes the assembly of the drive module 13, reduction module 14, and drill bit identification module convenient and quick, and also ensures a good seal.
[0042] In practical implementation, the easily observable bone drill power handle is achieved by housing the ranging module within the housing 20. The housing 20 is located at the end of the handle 11 opposite to the drilling direction of the bone drill bit, positioned directly above the doctor's hand. This location ensures unobstructed access during use, allowing the doctor to directly obtain the necessary signals. With this bone drill power handle, the ranging module can acquire real-time drilling depth data during use. The doctor can then determine the drilling depth based on this data and decide whether to continue using the bone drill power handle.
[0043] In some embodiments, the end of the shank member 11 opposite to the drilling direction of the drill bit has a recess, the bottom end of the housing portion 20 is connected to the recess, and the top end of the housing portion 20 protrudes from the top of the shank member 11. For example, Figures 1 to 4As shown, the recessed portion facilitates the installation of the housing portion 20, allowing the housing portion 20 to better integrate with the handle portion 11, and also reduces the size of the power handle without affecting the signal emitted by the ranging module, resulting in a more compact layout.
[0044] In some embodiments, the housing portion 20 has a through hole 22 at one end facing the drilling direction of the drill bit. The through hole 22 communicates with the receiving cavity, and the ranging signal generated by the ranging module is transmitted to the drilling direction of the drill bit through the through hole 22. For example, Figure 1 , Figure 3 and Figure 4 As shown, the signal emitted by the ranging sensor 30 of the ranging module is transmitted through the through hole 22 to facilitate real-time detection of the drill bit's depth. By placing the ranging module inside the housing 20 and at the front of the housing 20, the drill bit's depth can be detected in a timely and intuitive manner.
[0045] In some embodiments, a display screen 40 is provided at the end of the chamber 20 opposite to the direction of the drill bit. The display screen 40 is electrically connected to the ranging module via a circuit board and is used to display the drilling depth data acquired by the ranging module. The display screen 40 is used to display the drilling depth data acquired by the ranging sensor 30 in the ranging module, so as to provide intuitive feedback to the doctor for quick judgment. The ranging sensor 30 is connected to the circuit board to transmit its ranging signal. The circuit board is connected to the display screen 40 via signal pin 41. The display screen 40 is electrically connected to the controller, realizing signal transmission while reducing the number of wiring connections.
[0046] In some embodiments, a display screen housing 42 is further included, which covers the periphery of the display screen 40 and is connected to the end of the housing 20 opposite to the drilling direction of the drill bit. For example, Figure 3 , Figure 4 As shown, the cover of the display screen 40 facilitates the fixed installation of the display screen 40 and also facilitates the disassembly and assembly of the display screen 40.
[0047] In some embodiments, a rear cover 21 is provided at one end of the chamber body 20 opposite to the drilling direction of the drill bit, and a hollow portion is provided at one end of the rear cover 21 opposite to the drilling direction of the drill bit, with the display screen 40 embedded in the hollow portion. For example, Figure 2 and Figure 4 As shown, the display screen 40 is located in the hollow part. When the bone drill power handle is in use, the display screen 40 is located just above the doctor's hand. This position can remain unobstructed when the bone drill power handle is in use, allowing the doctor to directly obtain the required signals.
[0048] In some embodiments, a display screen housing 42 is further included. The rear cover 21 is detachably connected to the housing body 20. The display screen housing 42 is disposed around the display screen 40 and is embedded in the hollow portion. The display screen housing 42 covers and protects the display screen 40 to facilitate protection of the display screen 40.
[0049] In some embodiments, a ranging housing 32 is fitted around the ranging module. The ranging module and the circuit board are electrically connected to the display screen 40 via signal pins 41. The ranging housing 32 is fastened to the display screen housing 42 and then housed within the receiving cavity. For example, Figure 3 , Figure 4 As shown, the ranging housing 32 facilitates the fixed installation of the ranging sensor 30, and the display screen housing 42 facilitates the fixed installation of the display screen 40. The ranging housing 32 and the display screen housing 42 are fastened together, which allows the display screen 40 and the ranging sensor 30 to be installed as a whole first, and then assembled into the receiving cavity after installation, which is convenient for disassembly and assembly.
[0050] In some embodiments, a locking assembly is provided between the hopper body 20 and the rear cover 21. The locking assembly is used to lock or open the hopper body 20 and the rear cover 21. Specifically, the locking assembly can be a bolt and nut, a snap-fit assembly, etc., which locks the hopper body 20 and the rear cover 21 after they are engaged. For example, threaded holes corresponding to the positions are provided on the hopper body 20 and the rear cover 21, and bolts are inserted into the threaded holes and tightened.
[0051] In some embodiments, both the compartment body 20 and the rear cover 21 are provided with corresponding locking holes. A locking tongue 23 is inserted into the locking hole to lock the compartment body 20 and the rear cover 21. One end of the locking tongue 23 located inside the compartment body 20 is connected to a locking plate 24 and is elastically pressed against the locking plate 24. A locking plate button 25 aligned with the locking plate 24 is provided on the outside of the compartment body 20. Pressing the locking plate button 25 causes the locking plate 24 to elastically compress, and the locking tongue 23 moves out of the locking hole along with the locking plate 24, releasing the locking of the compartment body 20 and the rear cover 21.
[0052] In specific embodiments, such as Figure 4 and Figure 5As shown, the chamber body 20 and the rear cover 21 are detachably connected, facilitating the easy disassembly and assembly of the ranging component and the electronic control component. Before using the bone drill power handle, it needs to be disinfected. To protect the ranging component and the electronic control component, the rear cover 21 can be opened to remove the internal ranging component and electronic control component, and then the bone drill power handle can be disinfected before being reassembled. Specifically, both the chamber body 20 and the rear cover 21 have two corresponding locking holes, which are located in a straight line. There are two locking tongues 23, which extend into the two locking holes respectively to lock the chamber body 20 and the rear cover 21. The locking plate 24 is U-shaped, with metal elastic plates at both ends. Opening it outwards can respectively abut the two locking tongues 23. The end located inside the chamber body 20 is engaged with the end of the locking plate 24. When the two ends of the locking plate 24 are tightened inwards, it also drives the two locking tongues 23 to move inwards. One end of the locking button 25 extends out of the compartment body 20, and the other end of the locking button 25 abuts against the side walls at both ends of the locking plate 24. By pressing the locking button 25 from the outside of the compartment body 20 inward, the two ends of the locking plate 24 can be tightened inward. When it is necessary to remove the rear cover 21, by pressing the locking button 25, the two ends of the locking plate 24 are elastically tightened inward. The two ends of the locking plate 24 drive the locking tongue 23 to move inward out of the locking hole, releasing the locking of the compartment body 20 and the rear cover 21, so that the rear cover 21 can be removed from the compartment body 20.
[0053] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
