Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a multifunctional precision instrument rust removal pen. Background Technology
[0002] In the medical field, precision tubular instruments play an indispensable role in medical procedures due to their unique structure and material properties. However, these instruments also face some challenging problems. Due to their complex structure and expensive materials, incomplete cleaning is easily achieved during cleaning and use, leading to rust re-accumulation. Rust is particularly prone to build-up and residue at joints or intricate toothed structures, which not only severely impacts the instrument's performance and lifespan but also poses a potential threat to patient health.
[0003] Currently, common rust removal methods on the market mainly rely on rust removers and rust-removing wipes. However, these traditional methods have many drawbacks. On the one hand, for some stubborn rust stains, rust removers and rust-removing wipes are often ineffective in completely removing them, resulting in unsatisfactory rust removal results. On the other hand, in medical cleaning procedures, instruments need to be inspected and sealed after cleaning. However, existing inspection methods have limitations; some tiny rust stains or dirt hidden in the crevices of instruments are difficult to detect with the naked eye. This can easily lead to problematic instruments being mistakenly sealed and used, posing a threat to medical safety. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a multifunctional precision instrument rust removal pen to solve the problem of inadequate cleaning of existing medical instruments.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution:
[0006] A multifunctional precision instrument rust removal pen includes a pen barrel, which is hollow inside. One end of the pen barrel is connected to a connecting rod, and a rust removal pen tip is detachably connected to the connecting rod. The rust removal pen tip is water-absorbing. The end of the pen barrel facing the connecting rod is also equipped with a lamp head. A push-pull rod is passed through the end of the pen barrel away from the connecting rod. A piston is provided at the end of the push-pull rod inside the pen barrel, and an observation lens group is provided at the end of the push-pull rod extending outside the pen barrel. The observation lens group has optical magnification characteristics.
[0007] Optionally, the observation lens assembly includes a frame fixed to one end of the push-pull rod extending beyond the pen barrel and a lens embedded in the frame, the lens being a convex lens.
[0008] Optionally, the pen barrel has a handle at one end facing the connecting rod, and the connecting rod is located at the end of the handle away from the pen barrel. The connecting rod, the handle, and the pen barrel are connected as one unit. A core tube is provided inside the handle, and a liquid inlet is provided inside the connecting rod. The liquid inlet communicates with the internal space of the pen barrel through the core tube, and the liquid inlet and the core tube form a liquid inlet channel. The rust removal liquid inside the pen barrel is delivered toward the rust removal pen tip through the liquid inlet channel.
[0009] Optionally, the handle is configured as a flat structure, and the handle is smoothly connected to the pen barrel.
[0010] Optionally, the lamp head is arranged on one end face of the pen barrel away from the handle, and a pair of lamp heads are provided, with the pair of lamp heads distributed on both sides of the connecting rod.
[0011] Optionally, the handle has a cavity inside, in which a battery is installed, and a switch button is installed on the handle. The battery powers the lamp head, and the switch button controls the lamp head's on / off state.
[0012] Optionally, the handle is provided with an observation window, which is aligned with the core tube.
[0013] Optionally, the rust-removing pen tip includes a ring, one end of which is provided with a plug-in ring, and the other end of which is provided with a brush. The plug-in ring is threadedly connected to the end of the connecting rod away from the pen barrel. The end of the ring facing the plug-in ring is also provided with a sealing ring, which is fitted onto the plug-in ring.
[0014] Optionally, the brush is generally conical.
[0015] Optionally, the insertion ring is embedded with a sponge, and the end of the brush facing the ring is embedded inside the ring and fits against the sponge.
[0016] Compared with the prior art, this utility model has at least the following beneficial effects:
[0017] In the above solution, the push-pull rod and piston design allows for rapid extraction of rust-removing fluid. The fluid, delivered through a liquid supply channel, fully saturates the sponge in the rust-removing pen tip, ensuring continuous release during wiping and improving rust removal efficiency. Simultaneously, the tapered brush can reach deep into the crevices and corners of precision instruments, removing rust from hard-to-reach areas. This solves the problem of instruments requiring cleaning equipment and the inability of traditional rust-removing tools to completely remove rust.
[0018] By setting up an observation lens group with convex lenses, which have optical magnification characteristics, the rust on precision instruments can be magnified, allowing operators to observe the distribution and degree of rust removal more clearly, ensuring thorough rust removal, reducing rewashing work caused by rust recurrence or inadequate cleaning, and further improving work efficiency. The pair of lamp heads on the handle can provide sufficient lighting during rust removal operations, allowing operators to work in a well-lit environment, avoiding operational errors caused by insufficient light, and improving the accuracy and safety of rust removal.
[0019] This multi-functional precision instrument rust removal pen integrates multiple functions such as wiping and rust removal, lighting, and magnified observation. Operators can complete the rust removal and inspection of precision instruments without having to carry multiple tools, which greatly improves work efficiency. Attached Figure Description

[0035] like Figures 1 to 6 As shown, an embodiment of this utility model provides a multifunctional precision instrument rust removal pen, including a pen barrel 1, a connecting rod 2, a rust removal pen tip 3, a handle 4, a lamp head 5, a push-pull rod 8, and an observation mirror assembly 9. In this embodiment, the pen barrel 1 is a hollow cylindrical structure, the connecting rod 2 is located at one end of the pen barrel 1, and the push-pull rod 8 passes through the end of the pen barrel 1 away from the connecting rod 2. A piston 12 is provided at the end of the push-pull rod 8 located inside the pen barrel 1, and the piston 12 is tightly fitted to the inner wall of the pen barrel 1 and can slide along the inner wall of the pen barrel 1. An observation lens assembly 9 is installed at the end of the push-pull rod 8 that extends out of the pen barrel 1. The observation lens assembly 9 includes a lens frame 10 fixed to the end of the push-pull rod 8 that extends out of the pen barrel 1, and a lens 11 embedded in the lens frame 10. The lens 11 is a convex lens with optical magnification characteristics, which makes it convenient for operators to observe the rust on precision instruments. The observation lens assembly 9 has an overall elongated structure and is set along the length of the pen barrel 1. The end of the pen barrel 1 away from the connecting rod 2 has a larger diameter and is flat. After the push-pull rod 8 is pushed into the pen barrel 1, the observation lens assembly 9 can be retracted into the pen barrel 1 to avoid wear on the lens 11 during carrying.
[0036] like Figures 1 to 3 As shown, the handle 4 is located at the end of the pen barrel 1 facing the connecting rod 2. The handle 4 has a flat structure and is smoothly connected to the pen barrel 1 for easy gripping by the operator. The connecting rod 2 is connected to the end of the handle 4 away from the pen barrel 1. A pair of lamp heads 5 are arranged on the surface of the end of the handle 4 away from the pen barrel 1, distributed on both sides of the connecting rod 2, for providing illumination during rust removal operations. The handle 4 has a cavity 15 inside, in which a battery 16 is installed to power the lamp heads 5. A switch button 6 is also installed on the handle 4 for controlling the switching of the lamp heads 5.
[0037] like Figures 1 to 3 As shown, the connecting rod 2, handle 4, and pen barrel 1 are connected as a single unit through injection molding. A core tube 13 is installed inside the handle 4, and a liquid inlet 14 is opened inside the connecting rod 2. The liquid inlet 14 communicates with the internal space of the pen barrel 1 through the core tube 13, forming a liquid inlet channel. The rust remover inside the pen barrel 1 can be delivered towards the rust remover tip 3 through this liquid inlet channel. Furthermore, an observation window 7 is provided on the handle 4, aligned with the core tube 13, allowing the operator to easily observe the remaining rust remover in the pen barrel 1.
[0038] like Figures 3 to 5 As shown, the rust-removing pen tip 3 includes a circular ring 17, with a connecting ring 18 at one end and a brush 20 at the other end. The connecting ring 18 is threadedly engaged with the end of the connecting rod 2 away from the pen handle 1, enabling a detachable connection between the rust-removing pen tip 3 and the connecting rod 2. A sealing ring 21 is also provided at the end of the circular ring 17 facing the connecting ring 18, which is fitted onto the connecting ring 18 to provide a seal and prevent leakage of the rust-removing liquid. The brush 20 is conical in shape, facilitating rust removal operations on the gaps and corners of precision instruments. A sponge 19 is embedded inside the connecting ring 18. When the rust-removing liquid is delivered to the rust-removing pen tip 3 through the liquid supply channel, it can saturate the sponge 19, allowing the brush 20 to continuously release the rust-removing liquid during wiping, thus improving the rust-removing effect.
[0039] The workflow of the technical solution provided by this utility model is as follows:
[0040] Before using the multifunctional precision instrument rust removal pen, inject the rust removal liquid into the pen barrel 1. During operation, screw the ring 17 to separate the insertion ring 18 from the connecting rod 2, pull the push-pull rod 8 outwards, causing the piston 12 to move outwards within the pen barrel 1, creating a negative pressure inside the pen barrel 1. This draws the rust removal liquid from the connecting rod 2 into the pen barrel 1 through the liquid supply channel. Then, screw the ring 17 to connect the insertion ring 18 to the connecting rod 2. When rust removal of precision instruments is required, push the push-pull rod 8 inwards. The piston 12 squeezes the rust removal liquid inside the pen barrel 1, and the rust removal liquid is delivered to the connecting rod 2 through the liquid supply channel formed by the core tube 13 and the liquid supply hole 14, thereby saturating the sponge 19 embedded in the insertion ring 18.
[0041] The operator holds the handle 4 and uses the brush 20 of the rust-removing pen tip 3 to wipe the rusted areas of the precision instrument. Because the brush 20 is tapered, it can reach deep into the crevices and corners of the precision instrument. Simultaneously, the sponge 19 continuously releases rust-removing liquid, ensuring thorough contact between the liquid and the rust, thus achieving a good rust-removing effect. During the rust removal process, pressing the switch button 6 powers the lamp head 5, which then emits light to illuminate the rusted area, allowing the operator to easily observe the rust removal progress.
[0042] After rust removal is completed, operators can magnify and observe the rust on the precision instruments through the lens 11 of the observation lens group 9 to more clearly understand the distribution and degree of rust removal, ensuring thorough rust removal. In addition, the remaining amount of rust remover in the pen barrel 1 can be observed at any time through the observation window 7 so as to replenish the rust remover in a timely manner.
[0043] This utility model encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this utility model. To provide the public with a thorough understanding of this utility model, specific details are described in detail in the preferred embodiments; however, those skilled in the art can fully understand this utility model without these details. Furthermore, to avoid unnecessary confusion regarding the essence of this utility model, well-known methods, processes, procedures, components, and circuits are not described in detail.
[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
