[0002] A medical drill is a power tool specifically designed for the medical field. It plays an indispensable role in surgery, primarily in orthopedic and dental procedures, enabling rapid and accurate cutting, drilling, and repair of bones and teeth.
[0003] During long-term use, bone debris can easily enter the rotary joint between the drill bit and the drill bit, leading to a decrease in the sensitivity of the device. Most existing cleaning devices only rinse the surface and neglect the interior, resulting in poor cleaning effectiveness. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rotary joint cleaning device for the connection between an orthopedic electric drill and the drill bit.
[0005] To achieve the above objectives, the present invention adopts the following technical solution: a rotary joint cleaning device for the connection between an orthopedic electric drill and a drill bit, comprising a cleaning chamber, a motor fixedly connected to the top of the cleaning chamber, a rotating shaft fixedly connected to the output end of the motor, the top of the rotating shaft extending into the interior of the cleaning chamber, two scraper grooves formed on the outer wall of the rotating shaft, multiple telescopic grooves formed on the inner wall of each of the two scraper grooves, multiple limit grooves formed on the inner wall of each of the two scraper grooves, a spring fixedly connected to the inner wall of each of the multiple telescopic grooves, a telescopic block fixedly connected to the other end of the spring, a scraper provided inside the scraper groove, multiple limit rods fixedly connected to the inner wall of each of the two scraper grooves, the other end of each of the multiple limit rods extending into the interior of the multiple limit grooves, and the inner wall of the scraper fixedly connected to the other ends of the multiple telescopic blocks and the multiple limit rods.
[0006] As a further description of the above technical solution:
[0007] The cleaning chamber has an outer guide channel inside its outer wall, and there are multiple outer guide channels. The bottom of the inner wall of each of the multiple outer guide channels has an inner guide channel. An inner nozzle is fixedly connected to the bottom of the inner wall of the cleaning chamber, and there are multiple inner nozzles. Each of the multiple inner nozzles is connected to the multiple inner guide channels.
[0008] As a further description of the above technical solution:
[0009] The multiple limiting grooves are arranged in an alternating pattern, and the multiple internal guide grooves are L-shaped.
[0010] As a further description of the above technical solution:
[0011] The inner walls of the multiple outer guide channels are provided with connecting holes, and there are multiple connecting holes. The inner walls of the cleaning chamber are provided with grooves, and there are multiple grooves. The inner walls of the multiple grooves are fixedly connected to external nozzles, and the multiple external nozzles are connected to the multiple connecting holes.
[0012] As a further description of the above technical solution:
[0013] The outer wall of the cleaning chamber is fixedly connected to a water inlet, and the cleaning chamber is connected to the top cover by bolts, with two bolts in total.
[0014] As a further description of the above technical solution:
[0015] The bottom of the cleaning chamber is fixedly connected to a support leg, and there are multiple support legs. The bottom of the cleaning chamber is also fixedly connected to a drain outlet, and there are multiple drain outlets. All of the drain outlets are connected to the interior of the cleaning chamber.
[0016] This utility model has the following beneficial effects:
[0017] 1. The rotary joint is fitted onto the outside of the rotating shaft. The motor connected to the bottom of the cleaning chamber runs, driving the rotating shaft to rotate. Two scraper grooves are opened on the outer wall of the rotating shaft. Due to the centrifugal force generated when the rotating shaft rotates, the scrapers inside the scraper grooves move outwards. Multiple telescopic blocks connected to the inner wall of the scrapers move outwards along the telescopic grooves. At this time, the springs connected to the inner walls of the multiple telescopic blocks are in a stretched state, which in turn drives the two scrapers to rotate together. After the inner wall of the rotary joint is cleaned, the motor stops running, the multiple springs return, and the two scrapers return to their positions. The cleaning of the inner wall of the rotary joint is convenient and quick, ensuring the cleanliness of the inner wall of the rotary joint. Most existing cleaning devices only rinse the surface and neglect the inside, resulting in poor cleaning effect. This device can clean the inner wall of the rotary joint, working together with the outer wall cleaning to make the cleaning of the rotary joint more comprehensive.
[0018] 2. After the rotary joint is placed into the cleaning chamber, the top cover is installed on the top of the cleaning chamber with two bolts. The protrusion at the lower end of the top cover presses against the top of the rotary joint, thereby pressing the rotary joint tightly. The outer guide channel is opened inside the outer wall of the cleaning chamber. The external water flow enters the outer guide channel through the water inlet. Then the water flow enters multiple connecting holes and multiple inner guide channels, so that the inner and outer nozzles respectively rinse the inner and outer walls of the rotary joint. The cleaned water is finally discharged outside the cleaning chamber through the drain outlet. Attached Figure Description

[0030] The rotary joint is fitted onto the outside of the rotating shaft 3. The motor 2 connected to the bottom of the cleaning chamber 1 runs, driving the rotating shaft 3 to rotate. Two scraper grooves 4 are opened on the outer wall of the rotating shaft 3. The scraper 9 inside the scraper groove 4 moves outward from the rotating shaft 3 due to the centrifugal force generated when the rotating shaft 3 rotates. Multiple telescopic blocks 8 connected to the inner wall of the scraper 9 move outward together along the telescopic groove 5. At this time, the springs 7 connected to the inner walls of the multiple telescopic blocks 8 are in a stretched state, thereby driving the two scrapers 9 to rotate together. After the inner wall of the rotary joint is cleaned, the motor 2 stops running, the multiple springs 7 return, and the two scrapers 9 return to their positions.
[0031] The cleaning chamber 1 has multiple external guide channels 11 on its outer wall. Each external guide channel 11 has an internal guide channel 12 at its bottom. Multiple internal nozzles 13 are fixedly connected to the bottom of the inner wall of the cleaning chamber 1. Each internal nozzle 13 is connected to one of the multiple internal guide channels 12. Multiple limiting grooves 6 are arranged in an alternating pattern. The multiple internal guide channels 12 are L-shaped. Multiple connecting holes 14 are provided on the inner walls of the multiple external guide channels 11. Multiple grooves 15 are provided on the inner wall of the cleaning chamber 1. Multiple external nozzles 16 are fixedly connected to the inner walls of the multiple grooves 15. Multiple external nozzles 16 are connected to the multiple connecting holes 14. A water inlet 17 is fixedly connected to the outer wall of the cleaning chamber 1. The cleaning chamber 1 is connected to the top cover 18 by two bolts 19.
[0032] An external guide channel 11 is provided inside the outer wall of the cleaning chamber 1. External water flows into the external guide channel 11 through the inlet 17. Then, the water flows into multiple connecting holes 14 and multiple internal guide channels 12, thereby causing the internal nozzle 13 and the external nozzle 16 to rinse the inner and outer walls of the rotary joint respectively.
[0033] The bottom of the cleaning chamber 1 is fixedly connected with support legs 20, and there are multiple support legs 20.

The water after cleaning is finally discharged to the outside of the cleaning chamber through the drain outlets 21.
[0034] Working principle: The rotary joint is fitted onto the outside of the rotating shaft 3. Then, the top cover 18 is connected to the top of the cleaning chamber 1 by two bolts 19. External water flows into the outer guide groove 11 through the inlet 17, and then the water flows into multiple connecting holes 14 and multiple inner guide grooves 12, thereby causing the inner nozzles 13 and the outer nozzles 16 to rinse the inner and outer walls of the rotary joint, respectively. Then, the motor 2 runs, driving the rotating shaft 3 to rotate. Two scraper grooves 4 are opened on the outer wall of the rotating shaft 3. The scraper 9 inside the scraper grooves 4 is affected by the rotation of the rotating shaft 3. The centrifugal force generated causes the rotating shaft 3 to move outward. Multiple telescopic blocks 8 connected to the inner wall of the scraper 9 move outward along the telescopic groove 5. At this time, the springs 7 connected to the inner walls of the multiple telescopic blocks 8 are in a stretched state, which in turn drives the two scrapers 9 to rotate together. After the inner wall of the rotary joint is cleaned, the motor 2 stops running, the multiple springs 7 return to their original positions, and the two scrapers 9 return to their original positions. After the rotary joint is cleaned, the cleaned water flows out of the cleaning chamber 1 through multiple drain ports 21. Then, the top cover 18 is opened and the rotary joint can be taken out.
