Technical Field
[0001] This utility model relates to the field of medical equipment, and in particular to a battery pack for an orthopedic electric drill that is easy to disassemble. Background Technology
[0002] An orthopedic drill is a precision power tool specifically designed for orthopedic surgery. It is mainly used for drilling holes in bones, installing fixation devices, or implanting artificial joints. In orthopedic surgery, the electric bone drill is a key power tool, and its battery life and ease of operation directly affect the efficiency and safety of the surgery.
[0003] In existing technologies, the battery pack of orthopedic motors is usually installed inside the handle of the drill and sealed and fixed at the bottom with a flip-up cover. Since orthopedic surgery requires extremely high instrument cleanliness, although the drill body and cutting tools can be disassembled and disinfected with sterilization equipment, it is difficult to achieve efficient and thorough disinfection of the battery pack, which needs to be stored at room temperature in a dry place. At the same time, in order to ensure the reliability of the connection, the battery pack and the handle housing often adopt an interference fit design, which is prone to wear after repeated use, resulting in increased disassembly resistance, and even requiring the use of auxiliary tools to separate them, which seriously affects the continuity of the surgical process. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a conveniently disassembled orthopedic electric drill battery pack, which aims to solve the problem in the prior art that "orthopedic surgery has extremely high requirements for the cleanliness of instruments. Although the electric drill body and cutting tools can be disassembled and disinfected with disinfection equipment, it is difficult to achieve efficient and thorough disinfection for battery packs that need to be stored in a dry place at room temperature".
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery pack for easy disassembly of an orthopedic drill, comprising a housing, a handle fixedly connected to the bottom of the housing, a power supply battery disposed on the inner wall of the handle, and a quick-release mechanism disposed on the outer wall of the power supply battery. The quick-release mechanism includes an installation component, which includes an outer shell and a connecting seat. The outer shell is fitted onto the outer wall of the power supply battery, and the connecting seat is fixedly connected to the bottom of the handle. A base plate is detachably connected to the bottom of the outer shell, and an installation block is slidably connected to the outer wall of the base plate. A button is slidably connected to the inner wall of the installation block, and the button is elastically connected to the installation block by a spring. A push frame is fixedly connected to the outer wall of the button, a push block is fixedly connected to the upper surface of the push frame, and an elastic locking block is fixedly connected to the outer wall of the push frame.
[0006] As a further description of the above technical solution:
[0007] The quick disassembly and assembly mechanism also includes a stable disassembly and assembly component, which includes a sliding rod. A magnetic block is fixedly connected to the outer wall of the sliding rod, and a gear is fixedly connected to the outer wall of the sliding rod. A rack is fixedly connected to the inner wall of the handle, and a push rod is rotatably connected to the outer wall of the sliding rod. A magnetic sheet is fixedly connected to the upper surface of the outer shell.
[0008] As a further description of the above technical solution:
[0009] The pusher frame is slidably connected to the inner wall of the mounting block, and the pusher block is slidably connected to the inner wall of the mounting block.
[0010] As a further description of the above technical solution:
[0011] The push rod is slidably connected to the inner wall of the grip, the shape of the push rod is set to T-shape, and the bottom of the push rod is fixedly set to an inclined position.
[0012] As a further description of the above technical solution:
[0013] The elastic locking block engages with the inner wall of the connector.
[0014] As a further description of the above technical solution:
[0015] The upper surface of the push block is inclined, and there are two sets of push blocks, which are symmetrically arranged with the center line of the mounting block as the axis of symmetry.
[0016] As a further description of the above technical solution:
[0017] The gear meshes with the rack, and the magnetic block and the magnetic plate attract each other.
[0018] As a further description of the above technical solution:
[0019] The stabilizing assembly is provided in two sets, and the two sets of stabilizing assembly are symmetrically arranged with the center line of the grip as the axis of symmetry.
[0020] This utility model has the following beneficial effects:
[0021] 1. In this invention, the outer shell and the base plate form an isolation structure, completely enclosing the power supply battery and preventing it from directly contacting the inner wall of the handle, thus blocking the path of cross-infection at the source. This design does not affect the requirement for the battery to be stored dry at room temperature, and allows the inner wall of the handle and the outer shell to be directly disinfected with sterilization instruments without worrying about battery storage restrictions. It effectively meets the high requirements for instrument cleanliness in orthopedic surgery, achieving efficient and thorough disinfection.
[0022] 2. In this invention, an elastic locking block provides initial fixation, while magnetic blocks and magnetic sheets enhance stability. During disassembly, pressing a button releases the fixation, and the magnetic blocks flip to generate a repulsive force, assisting in the ejection. No auxiliary tools are required throughout the process, reducing disassembly resistance, shortening assembly and disassembly time, avoiding surgical interruptions, and ensuring the continuous and safe progress of the surgery.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0031] Reference Figure 1 , Figure 2 and Figure 3This utility model provides an embodiment of an orthopedic drill battery pack that is easy to disassemble. It includes a housing 1 for mounting other components, a handle 2 fixedly connected to the bottom of the housing 1, and a power supply battery 3 disposed on the inner wall of the handle 2. The power supply battery 3 is an existing structure, achievable by those skilled in the art, and therefore will not be described in detail here. The outer wall of the power supply battery 3 is provided with a quick-release mechanism, which includes an installation component 4. The installation component 4 includes an outer shell 41 and a connecting seat 42. The outer shell 41 covers the power supply battery 3, preventing the battery, which cannot be thoroughly sterilized, from being directly placed into the inner wall of the handle 2 and causing cross-contamination. The outer shell 41 is fitted onto the outer wall of the power supply battery 3. The connecting seat 42 is fixedly connected to the bottom of the handle 2, and is used to cooperate with the mounting block 44 to fix the power supply battery 3 inside the handle 2. A base plate is detachably connected to the bottom of the outer shell 41. 43. After the power supply battery 3 is placed inside the outer shell 41, the base plate 43 closes the outer shell 41 to form an isolation effect. The outer wall of the base plate 43 is slidably connected to the mounting block 44, which is used to close the space inside the handle 2, so that the power supply battery 3 covered by the outer shell 41 can be installed and fixed. The inner wall of the mounting block 44 is slidably connected to the button 45, which is used to push the push frame 47 to move. The button 45 and the mounting block 44 are elastically connected by the spring 46. The spring 46 provides the spring force for the button 45 to return after being pressed. The outer wall of the button 45 is fixedly connected to the push frame 47, which is used to drive the push block 48 and the elastic locking block 49 to move. The upper surface of the push frame 47 is fixedly connected to the push block 48, which is used to cooperate with the stable disassembly and assembly component 5 to push the push rod 55. The outer wall of the push frame 47 is fixedly connected to the elastic locking block 49, which is used to lock inside the connecting seat 42 for fixation.
[0032] Reference Figure 1 , Figure 3 and Figure 5The quick-release mechanism also includes a stable assembly 5, which includes a sliding rod 51. The sliding rod 51 is used to move the magnetic block 52 upward. The magnetic block 52 is fixedly connected to the outer wall of the sliding rod 51, which cooperates with the magnetic piece 56 to stably install the outer shell 41 inside the handle 2. A gear 53 is fixedly connected to the outer wall of the sliding rod 51. The gear 53 can mesh and rotate with the rack 54 when the sliding rod 51 moves upward. The rack 54 is fixedly connected to the inner wall of the handle 2. A push rod 55 is rotatably connected to the outer wall of the sliding rod 51, which is used to push the sliding rod 51 upward. A magnetic piece 56 is fixedly connected to the upper surface of the outer shell 41, which cooperates with the magnetic block 52 to attract. The push rod 55 is slidably connected to the inner wall of the handle 2 and is supported and guided by the handle 2. The push rod 55 is T-shaped to facilitate the movement of the sliding rods 51 on both sides. The bottom of the push rod 55 is fixedly inclined to match the inclined surface of the push block 48. When the push block 48 pushes, it moves upward. The gear 53 meshes with the rack 54 and rotates together when the magnetic block 52 moves upward. The magnetic block 52 and the magnetic plate 56 attract each other. During the upward movement of the magnetic block 52, it is driven to rotate by the gear 53. After the two-stage flip, the magnetic block 52 and the magnetic plate 56 repel each other, which helps the outer shell 41 to detach from the handle 2. The magnetic block 52 and the magnetic plate 56 do not contact each other when they attract each other to avoid affecting the flip. There are two sets of stable disassembly and assembly components 5. The two sets of stable disassembly and assembly components 5 are symmetrically arranged with the center line of the handle 2 as the axis of symmetry.
[0033] Reference Figure 3 and Figure 4 The pusher 47 is slidably connected to the inner wall of the mounting block 44 and is pushed when the button 45 is pressed. The pusher 48 is slidably connected to the inner wall of the mounting block 44 and is supported and fixed by the mounting block 44. The elastic locking block 49 is locked into the inner wall of the connecting seat 42 and is fixed when locked into the inside of the connecting seat 42. The upper surface of the pusher 48 is set to be inclined to cooperate with the inclined surface of the push rod 55 to push it upward. There are two sets of pushers 48, and the two sets of pushers 48 are symmetrically arranged with the center line of the mounting block 44 as the axis of symmetry.
[0034] Working Principle: When installing the power supply battery 3, first insert the battery 3 into the outer casing 41, and seal the bottom of the outer casing 41 with the base plate 43 to form an isolation structure. Then, push the battery 3, encased in the outer casing 41, into the handle 2, causing the mounting block 44 to insert into the connecting seat 42. During this process, the elastic locking block 49, under the action of the spring 46, engages with the corresponding slot on the inner wall of the connecting seat 42, achieving initial fixation. Simultaneously, as the mounting block 44 is inserted into the connecting seat 42, the pushing block 48 moves upward with the pushing frame 47, its inclined surface contacting and sliding relative to the inclined surface at the bottom of the pushing rod 55, pushing the pushing rod 55 upward. The pushing rod 55 drives the sliding rods 51 on both sides to move upward, causing the magnetic block 52 to gradually approach the magnetic plate 56 on the upper surface of the outer casing 41. Due to the mutual attraction between the magnetic block 52 and the magnetic plate 56, the power supply battery 3 is further tightened and stably fixed inside the handle 2 under the action of magnetic force. Furthermore, when the sliding rod 51 moves upward, the gear 53 meshes with the rack 54 on the inner wall of the handle 2, causing the magnetic block 52 to rotate during its ascent. It eventually stops in the direction of the magnetic poles attracting the magnetic plate 56, enhancing the stability of the attraction. When the power supply battery 3 needs to be removed, pressing the button 45 moves the push frame 47 downward, overcoming the spring force of the spring 46 and causing the elastic block 49 to disengage from the inner wall of the connecting seat 42, releasing the initial fixation. Simultaneously, the push frame 47 drives the push block 48 downward, disengaging it from the push rod 55. The push rod 55 then moves downward under gravity or the reset mechanism, causing the sliding rod 51 and the magnetic block 52 to move downward. At this point, the gear 53 meshes with the rack 54 again, causing the magnetic block 52 to undergo two-stage flipping during its descent. Ultimately, the magnetic poles between the magnetic block 52 and the magnetic plate 56 become repulsive, generating a repulsive force that helps push the outer shell 41 along with the power supply battery 3 out of the handle 2, achieving quick and effortless disassembly.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
