Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of medical imaging, in particular to a lifting cover module and an angiography machine thereof. Background Art
[0002] With the continuous improvement of medical standards, major hospitals have applied angiography technology to various clinical operations. According to the characteristic that X-rays cannot penetrate the contrast agent, doctors inject the contrast agent into the blood vessels, and use the angiography machine to emit X-rays in cooperation with the contrast agent to lock the location of blood vessel lesions, which helps doctors detect the condition in time and adopt appropriate treatment plans, increasing the probability of patient recovery.
[0003] An angiography machine usually includes a C-arm, a lifting cover module, and an imaging module. The imaging module is connected to the C-arm through the lifting cover module, and the position of the imaging module is controlled by the elongation or shortening of the lifting cover module. However, the elongation and shortening of the lifting cover module will expose the internal screws and electrical structures, posing a safety risk and being unsightly. Summary of the Utility Model
[0004] Based on this, the utility model provides a lifting cover module for the above technical problems.
[0005] A lifting cover module applied to an angiography machine includes: a connection seat for connecting to the angiography machine; a lifting assembly connected to the connection seat; and an imaging module connected to an end of the lifting assembly away from the connection seat. Wherein, the lifting assembly at least includes a first-stage cover and a second-stage cover. The first-stage cover is connected to the connection seat, the inner diameter of the first-stage cover is greater than the outer diameter of the second-stage cover, and a part of the second-stage cover is located inside the first-stage cover. The second-stage cover can move axially along the first-stage cover. When the second-stage cover moves to the extreme position away from the connection seat, the first-stage cover and the second-stage cover at least partially overlap in the axial direction.
[0006] With such a setting, the connection seat is connected to the angiography machine, so the relative position of the connection seat is fixed. After the lifting assembly is connected to the connection seat, it can elongate or shorten relative to the connection seat, thereby driving the imaging module to rise or fall. Since the lifting assembly includes a first-stage cover and a second-stage cover, and the second-stage cover is located inside the first-stage cover, the movement of the second-stage cover is limited by the inner wall of the first-stage cover, and its movement is more stable. The overlapping part of the first-stage cover and the second-stage cover can block the internal structures between the second-stage cover and the first-stage cover, preventing the exposure of internal structures such as electrical wiring harnesses and screws between the two, which can not only play a protective role, but also make the appearance of the lifting cover module more concise and beautiful.
[0007] In one embodiment, the lifting housing module further includes a driving module installed inside the lifting component; both the first-level housing and the second-level housing are connected to the driving module, and the driving module can drive the second-level housing to move along the axial direction of the first-level housing.
[0008] In one embodiment, a fixing member is provided on the driving module, and the inner wall of the second-level housing is connected to the fixing member.
[0009] In one embodiment, the lifting component further includes a third-level housing connected to the driving module. The outer diameter of the third-level housing is smaller than the inner diameter of the second-level housing, and a part of the third-level housing is located inside the second-level housing. The driving module can drive the third-level housing to move along the axial direction of the second-level housing.
[0010] In one embodiment, the first-level housing, the second-level housing, and the third-level housing are all of cylindrical structures; the first-level housing includes a first part and a second part, and the cross-sections of the first part and the second part are both semi-circular. The first part and the second part are connected by a connecting member; and / or, the second-level housing includes a third part and a fourth part, and the cross-sections of the third part and the fourth part are both semi-circular. The third part and the fourth part are connected by a connecting member; and / or, the third-level housing includes a fifth part and a sixth part, and the cross-sections of the fifth part and the sixth part are both semi-circular. The fifth part and the sixth part are connected by a connecting member.
[0011] In one embodiment, the connecting member is a screw and / or a snap structure.
[0012] In one embodiment, a plurality of convex ribs are further formed on the inner wall of the third-level housing, and the convex ribs extend along the circumferential direction of the inner wall of the third-level housing.
[0013] In one embodiment, the plurality of convex ribs are uniformly spaced along the axial direction of the third-level housing.
[0014] In one embodiment, the first-level housing, the second-level housing, and the third-level housing are all in clearance fit.
[0015] An angiography machine includes the lifting housing module as described above and a C-arm, and the connecting seat is connected to the C-arm.
[0016] Compared with the prior art, in the present utility model, the lifting cover module is divided into multiple levels of covers (including a first-level cover, a second-level cover, and a third-level cover), and at least part of adjacent two-level covers overlaps. The internal structure between the first-level cover with a larger diameter and the first-level cover with a smaller diameter is covered by the first-level cover with a larger diameter, so that the appearance of the multi-level covers will not expose connection structures such as electrical wires and screws, thereby forming a more concise and beautiful appearance of the lifting cover module. Each level of cover is provided with two symmetrical parts for butt joint assembly. Therefore, during processing, they can be processed separately, reducing the processing difficulty, and it is also convenient for disassembly, facilitating the maintenance of the internal components of the lifting cover module after disassembly.

[0030] The present utility model provides a lifting cover module 100, which is applied to an angiography machine 200, can drive the imaging module 30 to move, and avoids the exposure of structures such as screws 41 during the movement process, making it more aesthetically pleasing.
[0031] Please refer to Figures 1-3 and Figure 5 , the lifting cover module 100 includes a connecting seat 20, a lifting component 10 and an imaging module 30. The connecting seat 20 is connected to the C-arm 201 of the angiography machine 200. The lifting component 10 is connected to the connecting seat 20. The imaging module 30 is connected to the end of the lifting component 10 away from the connecting seat 20. Among them, the lifting component 10 at least includes a first-stage cover 11 and a second-stage cover 12. The first-stage cover 11 is connected to the connecting seat 20. The inner diameter of the first-stage cover 11 is larger than the outer diameter of the second-stage cover 12. And a part of the second-stage cover 12 is located inside the first-stage cover 11 and can move along the axial direction of the first-stage cover 11 (the axial movement here refers to the movement along the axis direction of the lifting component 10). When the second-stage cover 12 moves to the limit position away from the connecting seat 20, the first-stage cover 11 and the second-stage cover 12 at least partially overlap in the axial direction. In this way, the connecting seat 20 is connected to the angiography machine 200, so the relative position of the connecting seat 20 is fixed. After the lifting component 10 is connected to the connecting seat 20, it can extend or shorten relative to the connecting seat 20, thereby driving the imaging module 30 to rise or fall. Since the lifting component 10 includes the first-stage cover 11 and the second-stage cover 12, and the second-stage cover 12 is located inside the first-stage cover 11, the movement of the second-stage cover 12 is limited by the inner wall of the first-stage cover 11, and its movement is more stable. The second-stage cover 12 and the first-stage cover 11 at least partially overlap, so the overlapping part of the first-stage cover 11 and the second-stage cover 12 can block the internal structures between the second-stage cover 12 and the first-stage cover 11, avoiding the exposure of internal structures such as electrical wiring harnesses and screws 41 between the two, which can not only play a protective role, but also make the appearance of the lifting cover module 100 more concise and aesthetically pleasing.
[0032] In this embodiment, the imaging module 30 is set as a flat panel detector module, which includes a flat panel detector (not shown in the figure) and a flat panel cover assembly 31. The flat panel detector is located inside the flat panel cover assembly 31 and is sleeved and protected by the flat panel cover assembly 31.
[0033] Furthermore, the lifting cover module 100 further includes a driving module 50. The driving module 50 is installed inside the lifting component 10, connected to the first-level cover 11 and the second-level cover 12, and capable of driving the second-level cover 12 to move axially along the first-level cover 11 away from the connecting seat 20. In this way, the driving module 50 can provide driving force for the movement of the first-level cover 11 and the second-level cover 12. And the driving module 50 being arranged inside the lifting component 10 can reduce the occupied space, and can guide the movement of the above two through its abutment with the first-level cover 11 and / or the second-level cover 12.
[0034] Specifically, a fixing member 51 is provided on the driving module 50, and the inner wall of the second-level cover 12 is connected to the fixing member 51 to facilitate the connection between the second-level cover 12 and the driving module 50.
[0035] Preferably, the fixing member 51 is of an annular structure and sleeved on the outer peripheral side of the driving module 50. The inner wall of the second-level cover 12 is circumferentially connected to the outer wall of the fixing member 51. Therefore, the connection area between the two is larger and the connection strength is higher.
[0036] Specifically, the fixing member 51 adopts a steel belt structure, which has high material strength and is more durable, and can bear the long-term use of the second-level cover 12. The second-level cover 12 is connected to the steel belt by a plurality of screws, so that the driving module can drive the second-level cover 12 to move axially through the fixing member 51. In other embodiments, the first-level cover 11 and the second-level cover 12 can also be clamped by a limiting member to ensure partial overlap between the two. Or, instead of adding additional first and second limiting members 121 to achieve clamping, it is achieved through a change in its own diameter. For example, the inner diameter of the end of the first-level cover 11 close to the second-level cover 12 gradually decreases until it is smaller than the outer diameter of the second-level cover 12, and the outer diameter of the second-level cover 12 remains unchanged along the axial direction. Then, as the second-level cover 12 moves away from the first-level cover 11, the outer diameter of the second-level cover 12 can naturally be clamped with the inner wall of the first-level cover 11, thus realizing the fixed limit between the two.
[0037] The lifting component 10 further includes a third-level cover 13. The third-level cover 13 is connected to the driving module 50. The outer diameter of the third-level cover 13 is smaller than the inner diameter of the second-level cover 12, and a part of the third-level cover 13 is located inside the second-level cover 12. The driving module 50 can drive the third-level cover 13 to move axially along the second-level cover 12 and make the second-level cover 12 and the third-level cover 13 at least partially overlap in the axial direction. In this way, similar to the cooperation between the second-level cover 12 and the first-level cover 11, the third-level cover 13 is located inside the second-level cover 12, and its axial movement is limited by the inner wall of the second-level cover 12, so the movement is more stable. The second-level cover 12 and the third-level cover 13 also have partial overlap, so the second-level cover 12 can block the internal structure between the third-level cover 13 and the second-level cover 12.
[0038] In other embodiments, in order to meet the working requirements, the lifting assembly 10 can also be provided with a fourth housing and a fifth housing, etc., to further extend the moving length that the lifting assembly 10 can provide. In this embodiment, the lifting housing module 100 including three sections of housings is taken as an example for detailed description.
[0039] The first-stage housing 11 includes a first part 111 and a second part 112. The cross-sections of the first part 111 and the second part 112 are both semi-circular. The first part 111 and the second part 112 are connected by a connecting member 40; and / or, the second-stage housing 12 includes a third part 122 and a fourth part 123. The cross-sections of the third part 122 and the fourth part 123 are both semi-circular. The third part 122 and the fourth part 123 are connected by a connecting member 40; and / or, the third-stage housing 13 includes a fifth part 131 and a sixth part 132. The cross-sections of the fifth part 131 and the sixth part 132 are both semi-circular. The fifth part 131 and the sixth part 132 are connected by a connecting member 40. In this way, the first-stage housing 11, the second-stage housing 12, and the third-stage housing 13 can all be formed by the fitting connection of two parts. Therefore, whether it is when machining the first-stage housing 11, the second-stage housing 12, and the third-stage housing 13, or when assembling the first-stage housing 11, the second-stage housing 12, and the third-stage housing 13 together, the process is simpler and the cost is lower.
[0040] Therefore, in this embodiment, the first-stage housing 11, the second-stage housing 12, and the third-stage housing 13 are all composed of two parts, and the two parts are symmetrical structures. Of course, in other embodiments, any one or more of the first-stage housing 11, the second-stage housing 12, and the third-stage housing 13 can also be integrally formed to improve the structural strength.
[0041] Preferably, the connecting member 40 is a screw 41 and / or a snap structure 42. The screw 41 is screwed into the first part 111 and the second part 112 (if it is the second-stage housing 12, it is the third part 122 and the fourth part 123; if it is the third-stage housing 13, it is the fifth part 131 and the sixth part 132) to realize the connection between the first part 111 and the second part 112. Moreover, snap structures 42 are also provided at the edges of the first part 111 and the second part 112 that are close to each other. One of them is provided with a bayonet, and the other is provided with a buckle body. The buckle body is snapped into the bayonet to form a snap connection.
[0042] In addition, a plurality of convex ribs 133 are formed on the inner wall of the third-stage housing 13. The convex ribs 133 extend along the circumferential direction of the inner wall of the third-stage housing 13, and the plurality of convex ribs 133 are used to abut against the outer wall of the driving module 50. Therefore, when the third-stage housing 13 moves, the convex ribs 133 abut against the outer wall of the driving source to further guide the moving direction of the third-stage housing 13, and the convex ribs 133 also improve the structural strength and bending resistance of the third-stage housing 13, making it more durable.
[0043] Preferably, multiple ribs 133 are arranged at uniform intervals along the axial direction of the third-level housing 13. Therefore, the multiple ribs 133 can provide a more stable clamping effect and balanced bending resistance.
[0044] Taking the lifting housing module 100 having a first-level housing 11, a second-level housing 12, and a third-level housing 13 as an example, the drive module 50 in this embodiment includes a first module, a second module, and a third module. The first-level housing 11 is connected to the first module, the second-level housing 12 is connected to the second module, and the third-level housing 13 is connected to the third module. The first module, the second module, and the third module can be driven by a motor to move in the axial direction to drive the third-level housing in this embodiment to move.
[0045] In this embodiment, the first-level housing 11, the second-level housing 12, and the third-level housing 13 are all in clearance fit. Therefore, the relative movement of the three is smoother, avoiding the occurrence of interference problems.
[0046] Please refer to Figure 6 , the drive module 50 includes a base 53, a first drive member 54, a first lifting member 55, a second drive member 56, and a second lifting member 57. The first drive member 54 is connected to the base 53 and is connected to the first lifting member 55. The first lifting member 55 is connected to the second-level housing 12 and can drive the second-level housing 12 to move along the axial direction. The second drive member 56 is connected to the base 53 and is connected to the second lifting member 57. The second lifting member 57 is connected to the third-level housing 13. The second drive member 56 can drive the third-level housing 13 to move along the axial direction through the second lifting member 57. Moreover, the first drive member 54 and the second drive member 56 can move towards each other or away from each other, and can move synchronously or asynchronously, so as to control the free movement of the second-level housing 12 and the third-level housing 13.
[0047] Please refer to Figure 4 , the present utility model further provides an angiography machine 200. The angiography machine 200 includes a lifting housing module 100 and a C-arm 201. The connecting seat 20 is connected to the C-arm 201, and the side of the connecting seat 20 facing away from the lifting assembly 10 is an arc surface, and the radian of the arc surface is the same as the radian of the inner wall of the C-arm 201. The drive module 50 is connected to the C-arm 201 through sheet metal and is connected to the C-arm 201. The connecting seat 20 is adapted to the radian of the inner wall of the C-arm 201. Therefore, the connection between the connecting seat 20 and the C-arm 201 is closer, the connection strength is higher, and the position of the lifting housing module 100 is ensured to be stable.
[0048] Compared with the prior art, in the present utility model, the lifting cover module 100 is divided into multiple levels of covers (including a first-level cover 11, a second-level cover 12, and a third-level cover 13), and at least part of adjacent two-level covers overlaps. The internal structure between the cover with a larger diameter and the cover with a smaller diameter is covered by the cover with a larger diameter, so that the appearance of the multiple-level covers will not expose connection structures such as electrical wires and screws 41, thereby forming a more concise and beautiful appearance of the lifting cover module 100. Each level of cover is provided to be assembled by butting two symmetrical parts. Therefore, it can be processed separately during processing, reducing the processing difficulty, and it is also convenient to disassemble, facilitating the maintenance of the internal components of the lifting cover module 100 after disassembly.
[0049] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
[0050] The above-described embodiments only represent several implementation manners of the present utility model, and the description thereof is relatively specific and detailed, but it should not be construed as a limitation on the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several deformations and improvements can be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the utility model patent shall be subject to the appended claims.
