Description

Technical Field

[0001] This invention relates to the field of mechanical parts processing technology, and in particular to a tip grinding device for conveniently fixing silicone hooks. Background Technology

[0002] Retractors are medical devices and surgical tools used to assist in the assembly and implantation of hip joint prostheses. Also known as retractors, their function is exactly what the name suggests: to open the incision and expose the surgical field. The types of retractors used vary depending on the surgical specialty. Open surgery is common in emergency surgeries in gastrointestinal, hepatobiliary, and thoracic surgery, as well as routine surgeries in breast and thyroid surgery. And wherever open surgery is performed, retractors are used.

[0003] Existing retractors require specialized grinding equipment to polish their tips during processing, aiming to minimize damage to the patient's skin during use. However, existing grinding equipment presents several challenges in polishing retractors:

[0004] 1. Existing grinding equipment typically performs grinding in a single station. Since multiple retractors are usually used during surgery, this grinding speed is low. In addition, the current grinding method usually uses a grinding wheel to grind the retractors, which makes it difficult to achieve precise grinding of the retractors. When defects are found and the retractors are reused, they can easily cause secondary injury to the patient.

[0005] 2. Existing grinding equipment typically requires continuous water spraying on the grinding hook during grinding to prevent it from deforming or being damaged due to overheating. However, the grinding wheel partially obstructs the water spray source, resulting in poor cooling. Furthermore, the water spraying process causes grinding debris to splash and makes the cooling water turbid over a large area. When the equipment is used repeatedly, a large amount of impurities will adhere to the surface of the hook, thus affecting its usability.

[0006] 3. Existing grinding equipment requires fixing the hooks during grinding by clamping their surfaces with two clamping plates. However, this clamping method is prone to loosening, which affects processing accuracy and damages the hooks. It is also difficult to quickly replace hooks at multiple stations, reducing grinding efficiency. Furthermore, it is difficult to position the clamping parts when changing them. Since medical hooks require high precision, any misalignment during installation will cause damage to a large number of hooks. Summary of the Invention

[0007] The purpose of this invention is to provide a tool for grinding the tip of a silicone hook that is convenient for fixing, in order to solve the problem in the background art that the hook is ground by a grinding wheel.

[0012] As a preferred embodiment of the present invention, an arc-shaped plate is fixedly installed inside the water tank near the annular inclined plate, and a sliding groove is opened inside the arc-shaped plate. An inlet end is fixedly installed at one end of the water inlet pipe near the arc-shaped plate.

[0019] Compared with the prior art, the beneficial effects of the present invention are:

[0020] 1. This invention, by setting up pads and a grinding cylinder, enables multi-station grinding when the hook body needs to be ground. This allows for convenient replacement of the hook body during grinding, resulting in continuous grinding and higher grinding efficiency. Furthermore, by setting up a grinding cylinder that cooperates with the hook tip for one-time forming grinding, the grinding precision can be improved.

[0021] 2. This invention, by setting up an annular inclined plate, a water pump, an arc-shaped plate, a magnetic plate, a first magnetic block, and a nozzle, allows the annular inclined plate to immerse the polished hook body in water during polishing, thus enabling the hook body to be cooled comprehensively and more effectively. Simultaneously, the magnetic connection between the magnetic plate and the first magnetic block ensures that the water pump's inlet continuously tracks and approaches the hook body. Upon activation, the water pump extracts water from the area near the hook body after it enters the water, effectively preventing large-scale contamination of the water tank. This keeps most of the water in the tank relatively clean, reducing the workload of circulation and extraction, and effectively targeting contaminated areas, reducing circulation difficulty and costs. Furthermore, the nozzle rinses the hook body with filtered water, preventing debris and dust from adhering to the hook body surface, resulting in a cleaner hook body.

[0022] 3. This invention, by setting up a top plate, a warning light, a second magnetic block, a third spring, and a plug rod, allows the second magnetic block to magnetically connect with the magnetic plate when the hook body is in use. At this time, the warning light will light up, and the pad will move to the designated position. This enables more accurate positioning when replacing the hook body. When replacing the hook body, the third spring can be compressed, and the plug rod will move out from inside the top plate. The top plate can then be directly removed, making the replacement of the hook body more convenient. Attached Figure Description

[0037] This invention discloses a tip grinding device for conveniently fixing silicone hooks, the working principle of which is as follows:

[0038] When the hook 9 needs to be polished, multiple pads 406 are set at the top of the annular inclined plate 405, and the hook 9 is installed on the surface of the pads 406. During polishing, the first motor 403 is started, and the first motor 403 drives the annular inclined plate 405 to rotate, so that the hook 9 can be polished in multiple positions. It is also convenient to replace other hooks 9 while polishing, so that the hook can be polished continuously and the polishing efficiency is higher. At the same time, the hydraulic cylinder 701 is started, and the hydraulic cylinder 701 drives the fixed rod 702 to move. The fixed rod 702 drives the mounting plate 703 to move, and the mounting plate 703 drives the polishing cylinder 705 to move. At this time, the polishing cylinder 705 is fitted onto the tip surface of the hook 9, so that the hook tip and the polishing cylinder 705 cooperate. Then, the second motor 704 is started, and the second motor 704 drives the polishing cylinder 705 to rotate, so that the tip of the hook 9 can be polished in one step, which can improve the polishing accuracy.

[0039] After grinding, the annular inclined plate 405 is rotated, immersing the ground hook 9 in cooling water. This allows the hook 9 to be cooled comprehensively after grinding, resulting in better cooling. Simultaneously, the magnetic plate 509 is magnetically connected to the first magnetic block 508. The arc-shaped plate 501 allows the water inlet end 503 to slide inside, ensuring the water inlet of the water pump 510 remains close to the hook 9. Then, by activating the water pump 510, it draws water from the area near the hook after it enters the water. The system continuously absorbs wastewater around the hook 9, thereby increasing the sewage discharge effect and effectively preventing large-scale pollution of the water tank 1. This ensures that most of the water in the water tank 1 remains in a relatively clean state, reducing the workload of circulation and extraction. It effectively extracts water from the polluted area, reducing circulation difficulty and costs. Furthermore, the water pump 510 filters the discharged wastewater through the filter box 601, and then the filtered water is rinsed onto the soaked hook 9 through the nozzle 603. This prevents debris and dust from adhering to the surface of the hook 9, making the hook 9 cleaner.

[0040] When using the hook 9, rotating the annular inclined plate 405 causes the second magnetic block 809 to magnetically connect with the magnetic plate 509, illuminating the warning light 810. At this point, the pad 406 moves to the designated position, alerting the worker that positioning is complete and the hook 9 can be replaced. To replace the hook 9, pull the lever 805, which compresses the third spring 806 and moves the insertion rod 808. The insertion rod 808 then moves out of the top plate 801. Pulling the handle 802 moves the top plate 801, allowing it to be easily removed. When the replacement is complete, the positioning rod 803 positions the top plate 801. The spring force of the third spring 806 then inserts the insertion rod 808 into the top plate 801, facilitating installation and replacement of the hook 9. This makes replacement more convenient.
