Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of medical equipment, and in particular to a C-arm support device and medical equipment. Background Art

[0002] C-arm X-ray machines are widely used in various types of internal and external surgeries. Depending on the type of surgery, different C-arm models are used, and the environmental requirements for the operating room vary. For example, minimally invasive interventional surgeries require minimal incisions and less stringent operating room cleanliness requirements. Orthopedic and surgical procedures, on the other hand, are mostly open procedures, requiring high operating room cleanliness standards and, accordingly, high equipment cleanliness requirements. Small and medium-sized C-arm devices commonly used in orthopedic and surgical procedures contain large components that require frequent movement and positioning, with C-arms being a typical example. These C-arms typically have open motion tracks and transmission mechanisms, with exposed moving parts. Contacting components wear during movement, generating fine metallic and non-metallic debris that can easily spread from the open motion track into the operating room environment, compromising operating room cleanliness.

[0003] Currently, hospitals typically use a transparent sterile cover over the C-arm to prevent dust. While this method is effective, it can also affect the operation of the device, potentially interfering with surrounding equipment and instruments, hindering the doctor's operation, and being aesthetically unpleasing.

[0032] Figure 1 and Figure 2 A diagram of a C-arm support device 100 is disclosed. Figure 1 and Figure 2As shown, the C-arm support device 100 includes a C-arm holder 10 and a C-arm 20 that can roll around the C-arm holder 10. The C-arm holder 10 is provided with an axle 31 and a steel wheel 32 that is provided on the axle 31 and can rotate around the axle 31. A steel rail 22 is embedded in the C-arm 20, and the embedded steel rail 22 engages with the steel wheel 32. During the movement of the C-arm 20, rolling friction occurs between the steel wheel 32 and the embedded rail 22, thereby generating metal debris. The metal debris adheres to the embedded steel rail 22 and is dispersed into the space from the open track surface of the C-arm 20 as the C-arm 20 moves up and down. A certain amount of debris will also adhere to the steel wheel 32, but the steel wheel 32 is always on the inner side of the C-arm holder 10 and is not the main cause of the debris dispersion.

[0033] In view of this, an embodiment of the present invention proposes an improved technical solution to solve the problem of wear debris spreading from the open track surface of the C-arm 20.

[0034] Figure 3 A partial perspective diagram of a C-arm support device 200 according to an embodiment of the present invention is disclosed. Figure 4 A three-dimensional schematic diagram of a C-arm 20 according to an embodiment of the present invention is disclosed. Figure 5 A partial schematic diagram of a C-arm 20 according to an embodiment of the present invention is disclosed. Figure 4 The cross-sectional structure along line BB is shown in FIG. Figures 3 to 5 As shown, a C-arm support device 200 according to one embodiment of the present invention includes a C-arm holder 10 and a C-arm 20 that can roll relative to the C-arm holder 10. A wheel axle assembly 30 is mounted on the C-arm holder 10. The C-arm holder 10 includes a pair of wheel axle assemblies 30 disposed on opposing inner sides of the C-arm holder 10. Multiple pairs of wheel axle assemblies 30 may be provided on the C-arm holder 10. Figures 6 to 8 1 shows an illustration of an axle assembly 30 according to one embodiment of the present invention. Figures 6 to 8 As shown, the wheel axle assembly 30 includes a wheel axle 31 mounted on the C-arm holder 10 and a guide wheel 32 disposed on the wheel axle 31 and rotatable around the wheel axle 31. The guide wheel 32 can be, for example, a steel wheel that plays a guiding and load-bearing role.

[0035] like Figure 5As shown, a motion track 21 is provided on the C-arm 20. The motion track 21 is arranged on opposite sides of the C-arm 20. The motion track 21 has a track open surface 210 for the wheel axle assembly 30 to roll through. A guide rail 22 cooperating with a guide wheel 32 is provided in the motion track 21 of the C-arm 20. The guide rail 22 is, for example, embedded in a pair of opposite curved surfaces of the motion track 21. The guide rail 22 can be, for example, a steel rail. The guide wheel 32 and the guide rail 22 are engaged with each other, which can play both a guiding role and a load-bearing role. The guide rail 22 on the C-arm 20 can roll around the guide wheel 32 on the C-arm holder 10, thereby driving the C-arm 20 to roll relative to the C-arm holder 10.

[0036] like Figure 5 As shown, the C-arm support device 200 according to the embodiment of the present invention further includes a track sealing device 40 , which can be used to seal the track open surface 210 of the C-arm 20 .

[0037] The C-arm support device 200 of the embodiment of the present invention determines the causes of the generation and spread of wear debris by analyzing the structure of the C-arm 20, and specifically designs a track sealing device 40 to maximize the closure of the track open surface 210 on the moving track 21 of the C-arm 20 that may carry wear debris, thereby minimizing the spread of wear debris to the external space.

[0038] In some embodiments, the track sealing device 40 of the present invention includes a track block 41 and a track sealing strip 42. The track block 41 is disposed on the C-arm 20. The track sealing strip 42 is disposed on the C-arm holder 10. The track sealing strip 42 can cooperate with the track block 41 to seal the track open surface 210 of the moving track 21, thereby preventing or reducing the spread of wear debris from the track open surface 210.

[0039] In one embodiment, the track baffles 41 include a pair of spaced-apart plates. A pair of slots 23 may be provided in the moving track 21 of the C-arm 20 . The pair of track baffles 41 are respectively inserted into the pair of slots 23 of the moving track 21 of the C-arm 20 . The track sealing strip 42 is provided at the interval between the pair of track baffles 41 .

[0040] Optionally, the track sealing strip 42 and the track baffle 41 are attracted together by magnetism. The track sealing strip 42 may include a magnetic sealing strip. For example, the track sealing strip 42 may be a metal material, such as a magnetic steel strip; or the track sealing strip 42 may be a non-metallic material similar to a refrigerator magnet. The track sealing strip 42 can be reliably attached to the track baffle 41 through magnetism, thereby closing the track open surface 210 of the C-arm 20 to prevent the spread of wear debris. At the same time, the magnetic track sealing strip 42 itself can absorb a portion of the magnetic metal wear debris, thereby further preventing the spread of wear debris. The wear debris enclosed inside the moving track 21 of the C-arm 20 or adsorbed on the magnetic track sealing strip 42 can be cleaned regularly during equipment maintenance.

[0041] like Figures 6 to 8 As shown, the axle assembly 30 of this embodiment of the present invention further includes a sealing strip bracket 33 disposed on the axle 31. A track sealing strip 42 is disposed on the sealing strip bracket 33, which can be used to tightly press the track sealing strip 42 onto a pair of track retaining plates 41. The sealing strip bracket 33 guides and supports the track sealing strip 42, preventing it from interfering with the guide wheel 32 and ensuring a secure fit with the track retaining plates 41.

[0042] In some embodiments, the sealing strip bracket 33 includes a first bracket 34 and a second bracket 35 disposed on opposite sides of the guide wheel 32. The track sealing strip 42 is mounted and supported on the first bracket 34 and the second bracket 35 to avoid interference with the guide wheel 32. The first bracket 34 and the second bracket 35 each include a rolling roller that can roll with the track sealing strip 42.

[0043] Optionally, the first bracket 34 includes a first roller 341 and a second roller 342 located on opposite sides of the axle 31, and the second bracket 35 includes a third roller 351 and a fourth roller 352 located on opposite sides of the axle 31. The first bracket 34 is provided with a first opening 343 and a second opening 344. The first opening 343 allows the first roller 341 to rotate freely while allowing the track sealing strip 42 to pass through the bottom end of the first roller 341. Similarly, the second opening 344 allows the first roller 341 to rotate freely while allowing the track sealing strip 42 to pass through the top end of the second roller 342. The second bracket 35 is provided with a third opening 353 and a fourth opening 354. The third opening 353 and the fourth opening 354 allow the third roller 351 and the fourth roller 352 to rotate freely, respectively.

[0044] like Figure 9As shown, the track sealing strip 42 may sequentially extend from the bottom end of the first roller 341, the top end of the third roller 351, the bottom end of the fourth roller 352, and the top end of the second roller 342. Figure 7 and Figure 9 As shown, the position of the first roller 341 is higher than that of the third roller 351, the position of the second roller 342 is lower than that of the fourth roller 352, and the top end of the third roller 351 is higher than the top end of the guide wheel 32, and the bottom end of the fourth roller 352 is lower than the bottom end of the guide wheel 32. Therefore, when the track sealing strip 42 is installed on the first bracket 34 and the second bracket 35, interference with the rotation of the guide wheel 32 can be avoided.

[0045] The C-arm support device 200 of the embodiment of the present invention can effectively solve the problem of wear debris spreading from the open track surface 210 of the motion track 21 of the C-arm 20, prevent wear debris contamination, and can be used in medical equipment with higher cleanliness requirements and operating room environments.

[0046] Furthermore, compared to existing sterile cover dust protection methods, the C-arm support device 200 of the present invention has no impact on the doctor's operation. Furthermore, the track sealing device 40 of the C-arm support device 200 of the present invention is disposed on the track open surface 210 of the motion track 21 of the C-arm 20, thereby having no impact on the product's appearance. The C-arm support device 200 of the present invention has a good appearance and is more aesthetically pleasing.

[0047] In addition, the C-arm support device 200 according to the embodiment of the present invention has a simple structure and is easy to implement.
