Description

Technical Field

[0001] This utility model relates to the field of storage device technology, and in particular to a moisture-proof storage device for medical drill bits. Background Technology

[0002] In medical surgical practice, especially in orthopedics and dentistry, precision drills are crucial surgical instruments. These drills are typically made of metal, are expensive, and require extremely high levels of surface smoothness and sharpness. Existing drill storage devices have significant shortcomings: First, humidity control in the storage environment is poor. Residual moisture on the drill surface after sterilization, or ambient humidity, can easily penetrate, causing corrosion and shortening instrument lifespan while potentially increasing the risk of surgical infection. Second, most storage devices lack effective structures for securing and protecting the drills. During storage and retrieval, drills are prone to collisions or friction against the hard inner wall of the container, causing tip damage or surface scratches, affecting surgical precision. Third, retrieval is inconvenient, especially with small drills or densely packed storage. Medical staff struggle to quickly and securely grasp the required drill, increasing operation time and posing a risk of puncture wounds. Finally, these devices generally lack effective drainage and active ventilation designs. If condensation or small amounts of liquid accidentally enter, they can easily accumulate at the drill storage location, accelerating the corrosion process. Utility Model Content

[0003] This utility model relates to a moisture-proof storage device for medical drill bits, which effectively solves the problems of moisture prevention, convenient access, and protection in drill bit storage.

[0004] In a first aspect, this utility model provides a moisture-proof storage device for medical drill bits, specifically comprising: a storage base; a cover rotatably mounted on the upper end of the storage base via a hinge; a locking post vertically disposed in the middle of the side wall of the storage base away from the hinge end of the cover; and storage inner boxes evenly spaced longitudinally distributed on the storage base, each inner box containing a single drill bit with its tip facing the hinge end of the cover, the cover enclosing the inner box within the storage base.

[0005] Optionally, the upper end of the storage base is a sloping structure that slopes downward toward the hinge end. The sloping structure is inclined at ten degrees, and the storage inner box is distributed on the sloping surface of the storage base. A ventilation and drainage groove runs through the storage base from left to right near the hinge end.

[0006] Optionally, a U-shaped handle is fixedly provided on the outer side wall of the front end of the cover, and a U-shaped locking groove that matches the locking post is provided in the side plate of the cover below the handle.

[0007] Optionally, the locking post is threaded, and a nut is screwed onto the locking post to connect the cover to the storage base.

[0008] Optionally, the storage inner box has a cover plate fixedly provided at the lower end of the top, and a retrieval notch extending through the left and right sides at the higher end of the top. Clamping lugs are provided on the left and right side walls of the storage inner box below the retrieval notch. The clamping lugs are made of rubber. A ventilation grille is embedded in the bottom plate of the inner cavity of the storage inner box below the cover plate. The bottom of the ventilation grille is connected to the ventilation drainage groove.

[0009] This utility model provides a moisture-proof storage device for medical drill bits, which has the following beneficial effects: In this invention, the upper end of the storage base is designed with an incline of approximately 10 degrees towards the hinge end. This structure effectively guides condensate or small amounts of liquid accidentally introduced into the device to flow naturally to a lower position, preventing accumulation in the drill bit storage area. The through-flow ventilation and drainage channels located at the lowest point of the incline (hinged end) serve as channels for liquid discharge, promptly removing accumulated liquid from the device. Furthermore, their through-flow design constitutes a key node in the passive ventilation system, promoting natural convection and exchange of air inside and outside the device. This ventilation effect is further enhanced at the inner storage box level. Ventilation grilles embedded in the bottom plate of each inner box directly connect to the ventilation and drainage channels of the base, allowing dry external air to flow into the bottom of the inner box while humid air inside is expelled, forming an air circulation path throughout the entire device. This continuously reduces the humidity of the storage microenvironment, effectively preventing drill bit corrosion. In addition, a baffle at the lower end of the incline of the inner storage box effectively prevents dust and droplets that may fall during opening or ventilation from directly entering the inner box or contacting the drill bit shank, maintaining cleanliness during storage.

[0010] Furthermore, the vertically distributed, independently stored inner boxes ensure that each drill bit is stored in isolation, avoiding the risk of collision and friction between them. When placed, the drill bit tips are uniformly oriented towards the lower part of the bevel (i.e., the hinge end). This directional design not only directs any potential liquid flow away from the delicate drill bit tip but also significantly reduces the possibility of accidental collisions between the tip and the cap when opening and closing. Rubber clamping lugs located near the bottom of the access port utilize the elasticity and high friction of rubber to gently and securely hold the tail (shank) of the drill bit, effectively preventing the drill bit from shaking, rolling, or accidentally slipping out within the inner box, avoiding damage caused by collisions with the hard box walls, and providing extra protection for the fragile tip. The cap opens and closes via a hinge. When closed, it completely encloses all inner boxes within the storage base, forming a relatively sealed space that effectively isolates external contaminants and moisture. The locking post located at the end of the storage base away from the hinge end engages with the corresponding U-shaped locking groove on the cap, supplemented by a nut locking mechanism, ensuring the stability and sealing reliability of the cap after closure.

[0011] Furthermore, the through-hole design at the high end of the inner casing's sloping surface provides medical staff with a spacious and intuitive operating window. This ergonomic design allows for easy insertion of fingers or instruments to grasp the drill bit's tail (usually the thicker part), enabling quick, accurate, and safe access and significantly improving work efficiency. The U-shaped lever at the front of the cap facilitates force application, making opening and closing the cap easier and smoother. Attached Figure Description

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the described embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0016] Please refer to Figures 1 to 4 Example 1: This utility model proposes a moisture-proof storage device for medical drill bits, comprising: a storage base 1; a cover 2 is rotatably mounted on the upper end of the storage base 1 via a hinge; a locking post 3 is vertically provided in the middle of the side wall of the storage base 1 away from the hinge end of the cover 2; and storage inner boxes 4 are evenly spaced longitudinally distributed on the storage base 1, with a single drill bit 5 placed in the inner cavity of the storage inner box 4, the tip of the drill bit 5 facing the hinge end of the cover 2, and the cover 2 sealing the storage inner box 4 in the storage base 1.

[0017] The upper end of the storage base 1 is a sloping structure that slopes downward toward the hinge end. The sloping structure is inclined at ten degrees. The storage inner box 4 is distributed on the sloping surface of the storage base 1. The storage base 1 has ventilation and drainage grooves 101 that run through it from left to right near the hinge end.

[0018] Among them, a U-shaped handle 201 is fixedly provided on the outer side wall of the front end of the cover 2, and a U-shaped locking groove 202 that matches the locking post 3 is provided in the side plate of the cover 2 below the handle 201.

[0019] The locking post 3 has threads, and a nut 301 is screwed onto the locking post 3. The nut 301 is used to connect the cover 2 to the storage base 1.

[0020] In Example 2, based on Example 1, an inner box 4 is provided. A cover plate 401 is fixedly provided at the lower end of the top of the inner box 4. A retrieval recess 402 is provided on the left and right sides of the other end of the top of the inner box 4. Clamping lugs 403 are respectively provided on the left and right side walls of the inner box 4 below the retrieval recess 402. The clamping lugs 403 are made of rubber. A ventilation grille 404 is embedded in the bottom plate of the inner box 4 below the cover plate 401. The bottom of the ventilation grille 404 is connected to the ventilation drainage groove 101.

[0021] The following provides further explanation and clarification of the various structures mentioned above: The storage base 1 forms the main support of the device. Its upper end is designed with a sloping structure that tilts at approximately 10 degrees towards the hinge end of the cover 2. This design plays a crucial role: when condensation occurs inside the device or a small amount of liquid accidentally enters, the sloping surface guides the liquid to flow naturally towards the lower part of the hinge end, preventing accumulation in the drill bit 5 storage area. Complementing the lower end of the sloping surface are through-flow ventilation and drainage channels 101, which serve as channels for liquid discharge, leading the collected liquid out of the device. Simultaneously, their through-flow design promotes air circulation inside and outside the device, creating passive ventilation and effectively reducing internal humidity, making them a key structural element for moisture prevention.

[0022] On the inclined surface of the storage base 1, evenly spaced storage boxes 4 are longitudinally distributed, each box independently storing a single drill bit 5. When placed, the drill bit 5's tip faces the hinge end of the cover 2, i.e., the lower part of the inclined surface. This orientation aligns with the drainage direction of the inclined surface, ensuring that any dripping liquid flows away from the precision drill bit 5's tip and into the drainage channel. It also reduces the risk of tip collision when opening and closing the cover 2. The cover 2 is mounted to the base via a hinge, its core function being to enclose all the storage boxes 4 within the storage base 1, forming a relatively sealed space that isolates most external moisture and contaminants. A U-shaped lever 201 is located at the front of the cover 2, facilitating user opening and closing. To ensure a secure seal when the cover 2 is closed, a locking post 3 is vertically positioned in the middle of the side wall of the storage base 1 away from the hinge end. A U-shaped locking groove 202, corresponding to the locking post 3, is provided on the cover 2. When closed, the locking post 3 engages with the locking groove 202 for initial positioning and blocking. To further enhance sealing and locking, the locking post 3 is threaded and screwed with a nut 301. Tightening the nut 301 will tightly press and fix the cover 2 onto the storage base 1.

[0023] Each storage box 4 is meticulously designed to provide moisture protection and easy access to the drill bit 5. A baffle 401 is fixed to the lower end of the sloping surface at the top. This baffle 401 effectively prevents dust and liquid droplets that may fall or drip from the higher part of the sloping surface, such as when the box is opened or during ventilation, from directly contacting the shank of the drill bit 5 or falling deep into the box. At the higher end of the sloping surface, the top of the storage box 4 has openings 402 on both sides, providing the main operating window for medical personnel to easily access and remove the drill bit 5 with their fingers or tools, especially suitable for operations where the drill bit 5 typically has a thicker tail. To securely hold the drill bit 5 and prevent it from colliding with the hard box walls, rubber clamping lugs 403 are provided on the left and right side walls of the storage box 4 below the clamping openings 402. The rubber material provides the necessary elasticity and friction, gently and securely clamping the tails of drill bits 5 of different diameters, preventing them from shaking or slipping, and absorbing minor vibrations to protect the drill bit 5. A ventilation grille 404 is embedded in the bottom plate of the inner cavity of the storage box 4 below the cover plate 401. This grille is a key moisture-proof structure of the inner box. The bottom of the ventilation grille 404 is directly connected to the ventilation drainage channel 101 that runs through the hinged end of the base. This allows dry air from the outside to flow in through the ventilation drainage channel 101 and then enter the bottom of the inner box through the ventilation grille 404, or allows humid air inside the inner box to be discharged through this path. This ensures that each individual inner box can effectively participate in the air circulation of the entire device, continuously dissipating moisture inside the box and preventing the drill bit 5 from corroding.
