Abstract
Description
Technical Field
[0001] This utility model relates to the field of drilling technology for medical devices, and in particular to a drilling device for a metal bone plate for rib orthopedic surgery. Background Technology
[0002] A rib orthopedic metal plate (commonly known as a rib plate or rib orthopedic plate) is a medical device used to repair rib fractures or deformities. It is usually made of metal (such as stainless steel or titanium alloy) and is specifically designed to fix, stabilize, and correct rib injuries, promote fracture healing, or improve rib morphology. During the manufacturing process of a rib orthopedic metal plate, drilling is required.
[0003] A drilling device for medical device processing (authorization announcement number: CN219211670U) is currently available. It places a metal bone plate to be drilled on four support columns and connects two clamping devices to a drive rod via threads. A second motor drives the drive rod to rotate, bringing the two clamping devices closer together to clamp the metal bone plate on the four support columns, facilitating drilling. However, because the metal bone plate is placed on the four support columns, the portion of the plate to be drilled is suspended. When the drill bit drills downwards, it exerts a downward force on the metal bone plate, easily causing deformation and bending during drilling, affecting the quality of the finished metal bone plate. Furthermore, metal debris generated during drilling scatters around the perimeter, making cleaning difficult. Therefore, a drilling device for metal bone plates used in rib and sternal orthopedics is proposed to solve the above problems. Utility Model Content
[0004] To address the shortcomings of existing technologies, this utility model provides a drilling device for metal bone plates used in rib and sternal orthopedics, thereby solving the aforementioned problems.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:

One end of each of the two circular plates is fixedly installed on the bottom side of each circular plate, and the other ends of each of the two springs are fixedly installed on the top side of the cylindrical shell. Under the elastic force of the two springs, the protective cylinder can always cover the part of the metal bone plate used for rib orthopedic surgery to be drilled, and the protective cylinder can block the metal debris that is splashed during the drilling process.
[0012] Preferably, the debris collection mechanism includes a collection box, an exhaust fan, a suction hose, and suction nozzles. The collection box and the exhaust fan are respectively arranged on the top side of the top frame. The exhaust end of the exhaust fan extends into the collection box. One end of the suction hose is arranged on one side of the collection box. The other end of the suction hose is divided into two sections and extends into the cylindrical shell and the protective cylinder, and is provided with two suction nozzles.

[0024] Specifically, the screw drive mechanism includes a bidirectional threaded rod 5 and a grip plate 6. One end of the bidirectional threaded rod 5 is rotatably mounted on the inner wall of the corresponding mounting groove 3. The other end of the bidirectional threaded rod 5 is threaded through the two corresponding U-shaped clamping plates 4 and through the base frame 1, and is fixedly mounted on the grip plate 6.

[0025] Specifically, the bottom debris collection mechanism includes an external threaded ring 7 and an internal threaded collection cylinder 8. The external threaded ring 7 is fixedly installed at the bottom of the base frame 1, and the internal threaded collection cylinder 8 is threaded onto the external threaded ring 7. The internal threaded collection cylinder 8 is located below the drilled hole 2. The internal threaded collection cylinder 8 can collect the metal debris generated at the bottom of the drill bit 14. By unscrewing the internal threaded collection cylinder 8 out of the external threaded ring 7, the internal threaded collection cylinder 8 can be disassembled, making it convenient to process the metal debris collected in the internal threaded collection cylinder 8.
[0026] Furthermore, the drilling mechanism includes a motor 13 and a drill bit 14. The motor 13 is fixedly installed inside the cavity 12 of the cylindrical outer shell 11, and the output shaft of the motor 13 extends through to the outside of the cylindrical outer shell 11 and is fixedly installed on the drill bit 14.

[0030] In use: During the drilling process of the metal bone plate for rib orthopedic surgery, the operator places the metal bone plate in the groove of the base frame 1. By turning the two handle discs 6, the two bidirectional threaded rods 5 are simultaneously rotated, causing the two sets of U-shaped clamping plates 4 to move closer together to clamp and fix the metal bone plate, preventing deformation and bending during subsequent drilling. By activating the hydraulic rod 10 and the motor 13, the rotating drill bit 14 is driven downward to drill the clamped metal bone plate. When the bottom of the protective cylinder 15 contacts the metal bone plate, it causes the protective cylinder 15, the two sets of connecting rods 16, and the circular plate 17 to move upward. At this time, the two springs 18 are stressed and deformed, causing the protective cylinder 15 to... The protective sleeve 15 is placed over the area to be drilled on the metal bone plate for rib orthopedic surgery. The protective sleeve 15 can block the metal debris generated during the drilling process. At the same time, by starting the exhaust fan 20, the metal debris blocked by the protective sleeve 15 and the cylindrical outer shell 11 is transported to the collection box 19 through the suction hose 21 via the two suction nozzles 22. The metal debris sucked into the collection box 19 can be filtered by the two filter plates 23 inside the collection box 19, so that the metal debris generated during the drilling of the metal bone plate for rib orthopedic surgery is collected in the collection box 19. At the same time, when the drill bit 14 penetrates the metal bone plate for rib orthopedic surgery, the metal fragments generated at the bottom of the drill bit 14 fall into the internal thread collection cylinder 8, which can collect the metal fragments generated at the bottom of the drill bit 14.
