Description

Technical Field

[0001] This application relates to the field of medical device technology, and more specifically, to a tool for scraping away gouty tophi crystals. Background Technology

[0002] Gout is a metabolic disease caused by purine metabolism disorders or reduced uric acid excretion, and its incidence is increasing year by year. In gout patients, excessively high blood uric acid levels lead to the deposition of urate crystals in joints and other tissues, forming hard, yellow or white nodules known as tophi. These tophi not only affect the patient's appearance but also severely impair limb function, even leading to disability. Therefore, effective treatment of tophi is particularly important.

[0003] Currently, treatment strategies for gouty tophi mainly fall into two categories: non-surgical therapies and surgical removal. Non-surgical therapies, such as dietary optimization, medication, and lifestyle adjustments, can play a role in controlling the condition in its early stages, but their effectiveness is often limited when dealing with large, established tophi. In contrast, traditional surgical removal methods directly scrape away the tophi, which can directly remove the lesions, but faces many challenges in practice. During surgery, the tophi crystals, due to blood infiltration, exhibit strong viscosity and easily adhere to the scraping tools, increasing the difficulty of cleaning and the duration of the procedure. Furthermore, considering the high sensitivity of the patient's joints, improper temperature control during the cleaning process can easily cause discomfort and even increase the burden on the joints. Utility Model Content

[0004] To overcome the above deficiencies, this application provides a tool for scraping away gouty tophi crystals to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] A tool for scraping away gouty tophi includes a grip cylinder with a scraping component inserted into its bottom end. A cleaning device is installed on the grip cylinder, comprising a channel component, a pressure regulating component, and a heating component. The channel component is formed inside the grip cylinder and the scraping component. The bottom end of the pressure regulating component is bolted to the top end of the grip cylinder, and its interior communicates with the interior of the channel component. The heating component is installed inside the grip cylinder and surrounds the channel component.

[0007] Furthermore, the channel component includes water channel I and water channel II. Water channel I is provided at the center of the grip cylinder, and water channel II is provided inside the scraping component. Water channel II and water channel I are connected to each other.

[0008] Furthermore, the interior of the waterway II exhibits a gradient from coarse to fine from top to bottom.

[0009] Furthermore, the pressure regulating component includes a connecting pipe head and an adjusting switch. One end of the connecting pipe head is bolted to the surface of the grip cylinder, and the other end is equipped with the adjusting switch. The pipe head is internally connected to the interior of the water channel I.

[0010] Furthermore, the heating component includes four insertion slots and four electric heating rods. The surface of the grip cylinder is provided with four insertion slots at equal intervals around the water channel I. The top of each of the four insertion slots is provided with an internal thread. The four electric heating rods are respectively inserted into the four insertion slots and threadedly connected to the internal threads.

[0011] Furthermore, the scraping component includes an extension column and a scraping spoon. The extension column has the water channel II inside, and the scraping spoon is integrally formed on one side of the bottom end. The outer end of the scraping spoon corresponds to the water spray nozzle of the water channel II.

[0012] Furthermore, a limiting component is provided between the grip and the extension post.

[0013] Furthermore, the limiting component includes a second insertion groove, a threaded hole, a threaded head, and a retaining groove. The bottom end of the gripping cylinder is provided with the second insertion groove, and the side wall is provided with the threaded hole. The top of the second insertion groove has a sealing gasket and communicates with the interior of the waterway I. The side wall of the extension column is provided with the retaining groove and is inserted into the interior of the second insertion groove. The outer wall of the threaded head is threadedly connected to the inner wall of the threaded hole, and the inner end is tightly engaged with the interior of the retaining groove.

[0014] This utility model has the following beneficial effects:

[0015] This invention utilizes a built-in cleaning device within the grip to achieve immediate cleaning during the scraping of gouty tophi crystals. In particular, the gradually tapering structure of water channel II helps to increase water pressure, more effectively flushing and removing gouty tophi crystals adhering to the scraping spoon, thus improving surgical efficiency and cleanliness.

[0016] The introduction of this pressure regulating component allows doctors to precisely control the flow and pressure of the cleaning water by adjusting the switch according to the needs of the surgery, ensuring the cleaning effect while avoiding excessive stimulation of the patient's joints. Furthermore, the electric heating rod in the heating component can regulate the temperature of the cleaning water, maintaining it within a suitable and constant range, further improving patient comfort and reducing discomfort caused by abnormal temperatures.

[0017] The limiting component design between the gripper and the scraping component in this invention not only ensures the stability of the connection between the two but also facilitates quick disassembly and replacement, improving the flexibility and convenience of surgical operations. Simultaneously, the combined use of the insertion slot, threaded hole, threaded head, and retaining groove achieves a tight, secure connection, effectively preventing loosening or detachment during surgery.

Detailed Implementation

[0025] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

[0026] Example: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A tool for scraping gouty tophi crystals includes a grip 1, with a scraping component 2 inserted into the bottom of the grip 1; the scraping component 2 includes an extension post 21 and a scraping spoon 22; a limiting component 4 is provided between the grip 1 and the extension post 21; the limiting component 4 includes an insertion groove 41, a threaded hole 42, a threaded head 43 and a retaining groove 44.

[0027] The grip 1 is the part that the surgeon holds and uses to operate the entire scraping tool. The grip 1 is made of medical-grade material and has a non-slip texture on the surface to ensure that the surgeon can hold it firmly during the operation.

[0028] The scraping component 2 is located at the bottom of the inner end of the grip 4, and is used to directly contact and scrape away tophi crystals within the joint. This component can be adjusted according to the size and location of the tophi to adapt to different surgical needs. The extension column 21 is the main body of the scraping component 2, designed to be slender for easy access to narrow spaces such as joints for surgical operations. It has an internal water channel II 312, which precisely connects with water channel I 311 at the connection between the grip 1 and the scraping component 2, forming a continuous cleaning water flow channel. The outlet of water channel II 312 is located at the bottom of the extension column 21, and the water outlet direction is carefully designed to ensure that the cleaning water can be directly sprayed onto the working area of ​​the scraping spoon 22. The scraping spoon 22 is the execution part of the scraping component 2, integrally manufactured on one side of the bottom end of the extension column 21. Its shape and size are designed according to surgical needs, and it typically has a sharp scraping edge to effectively scrape away tophi crystals from the joint surface or tissue. The outer end of the scraping spoon 22 precisely corresponds to the spray nozzle of the water channel II 312 inside the extension column 21. This means that during the scraping process, cleaning water will be sprayed out from the spray nozzle, directly impacting the working surface of the scraping spoon 22 and the surrounding gouty tophi crystals, effectively preventing crystals from adhering to the scraping spoon, and improving surgical efficiency and cleanliness.

[0029] A limiting component 4 is added between the gripping cylinder 1 and the extension column 21. This design not only ensures the stable connection of the scraping component 2 during the operation but also prevents the cleaning water from leaking from the connection, ensuring the smooth progress of the operation. The insertion groove 41 is located at the center of the bottom end of the gripping cylinder 1, and its shape matches the insertion end of the extension column 21. The top of the insertion groove 41 has a built-in sealing gasket made of a soft and durable material, which forms a tight fit when the extension column 21 is inserted, effectively preventing the cleaning water from leaking from the connection. Simultaneously, the inside of the insertion groove 41 is connected to the water channel 311, ensuring that the cleaning water can flow smoothly to the scraping component 2. A threaded hole 42 is opened on the side wall of the gripping cylinder 1, adjacent to the insertion groove 41. The threaded hole 42 is designed to install a threaded head 43 to provide additional fixing force, ensuring that the extension column 21 will not accidentally fall off during the operation. The threaded head 43 is a fastener with external threads; its outer wall matches the inner wall of the threaded hole 42, and a threaded connection is achieved by rotation. The inner end of the threaded head 43 is designed with a structure that mates with the slot 44, so that it can be tightly engaged with the slot 44 during tightening, further enhancing the stability of the connection. The slot 44 is formed on the side wall of the extension post 21, and its position corresponds to the insertion slot 41 and the threaded hole 42. The shape and size of the slot 44 match the inner end of the threaded head 43. When the threaded head 43 is tightened, its inner end will be embedded in the slot 44, forming a stable engagement structure. At the same time, it facilitates the disassembly of the scraping component 2 and the replacement with a more suitable scraping component 2.

[0030] Please see Figure 1 , Figure 2 , Figure 4 , Figure 5 A tool for scraping away gouty tophi crystals includes a grip 1 with a cleaning device 3 mounted on it. The cleaning device 3 comprises a channel component 31, a pressure regulating component 32, and a heating component 33. The channel component 31 includes a water channel I 311 and a water channel II 312; the pressure regulating component 32 includes a connecting pipe head 321 and an adjusting switch 322; the heating component 33 includes four insertion slots 331 and four electric heating rods 332.

[0031] The channel component 31 is a key part that ensures the smooth flow of cleaning water to the scraping component 2 and effectively cleans the scraping area. Water channel I 311 is located at the center of the grip cylinder 1 and is a channel running through the interior of the grip cylinder 1. The top end of water channel I 311 connects to the interior of the pressure regulating component 32 to receive cleaning water from it. Water channel II 312 is located inside the extension column 21 of the scraping component 2 and is a channel extending from the top of the extension column 21 to the spray nozzle of the scraping scoop 22. The top end of water channel II 312 is designed as an interface to connect with water channel I 311 inside the grip cylinder 1. This interface must precisely match the bottom end of water channel I 311 to ensure that the cleaning water does not leak at the connection. The outlet of water channel II 312 is located at the outer end of the scraping scoop 22, and the spray direction is carefully designed to ensure that the cleaning water is sprayed directly onto the working area of ​​the scraping scoop 22. Furthermore, the water channel II 312, which serves as the connection between the internal water channel I 311 of the gripper 1 and the spray nozzle of the scraper 22, does not have a fixed internal diameter; instead, its diameter gradually decreases from top to bottom. This variable diameter design is based on the principles of fluid mechanics, which can accelerate the flow rate of the cleaning water and increase the spray pressure by reducing the cross-sectional area of ​​the channel.

[0032] The pressure regulating component 32, as a key component connecting the external water source and the internal water channel, directly affects the efficiency of the cleaning water delivery and the surgical outcome. The connecting pipe head 321 is the interface between the pressure regulating component 32 and the external water source or cleaning equipment. One end of it is designed with a bolt connection structure that matches the surface of the grip cylinder 1, achieving a stable connection through bolt tightening. The other end of the connecting pipe head 321 is used to install the regulating switch 322, and is connected to the inside of the regulating switch 322 through an internal channel. Simultaneously, this internal channel is also interconnected with the water channel I 311 inside the grip cylinder 1, ensuring that the cleaning water can smoothly enter the internal water channel from the outside. The regulating switch 322, installed at the end of the connecting pipe head 321, is used to regulate the pressure and flow rate of the cleaning water. The surgeon can rotate the regulating switch 322 to change the output state of the cleaning water according to the needs of the surgery.

[0033] The heating element 33 is designed to indirectly transfer heat into the water channel I 311, ensuring that the cleaning water maintains a suitable temperature when it reaches the scraping area. Insertion slots 331 are formed on the surface of the gripping cylinder 1 and are evenly distributed around the water channel I 311. This layout ensures that the electric heating rods 332 are evenly distributed along the path of the cleaning water flow, improving heating efficiency. Each insertion slot 331 has an internal thread at its top to match the threaded portion of the electric heating rod 332, achieving a secure threaded connection. This connection method not only facilitates installation and disassembly but also ensures that the electric heating rod 332 will not loosen or fall off during heating. The electric heating rod 332 is the core component of the heating element 33, used to convert electrical energy into heat energy and transfer it to the cleaning water. Each electric heating rod 332 is designed with a threaded portion that matches the internal thread of the insertion slot 331, ensuring a tight insertion and fixation within the insertion slot 331. The electric heating rod 332 has an embedded heating element, such as a heating wire. When the power is turned on, the heating element heats up rapidly and transfers the heat to the surrounding cleaning water. In addition, the electric heating rod 332 is also designed with temperature control devices, such as a temperature sensor and a temperature control switch, to monitor and adjust the heating temperature to ensure that the cleaning water is kept within a suitable range.

[0034] The working principle of this gout tophi removal tool is as follows: During the procedure, the doctor first injects cleaning water into the tool as needed and adjusts the flow rate and pressure to a suitable level using the pressure regulating component 32. Then, the heating component 33 is activated to heat the cleaning water to the set temperature. Once ready, the doctor inserts the scraping component 2 into the location of the gout tophi and uses the scraping spoon 22 to perform the scraping operation. Simultaneously, cleaning water enters waterway II 312 from waterway I 311 through the channel component 31 and is sprayed from the nozzle onto the outer end of the scraping spoon 22, providing immediate cleaning of the scraped area and effectively preventing gout tophi crystals from adhering to the scraping spoon.

The specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0036] The power supply and working principle of the camera 211, the laptop 212, and the servo motor 131 are clear to those skilled in the art and will not be described in detail here.
