At the same time, in this specification, the term "and / or" includes any and all combinations of the relevant listed items.
[0061] As described in the background technology, traditional displays and cameras are supported and moved in space by two adjustment arms respectively. When the doctor needs to adjust the field of view of the display according to his or her position, he or she usually needs to adjust the posture of the adjustment arm of the display. However, since the spatial movement of the adjustment arm of the camera and the adjustment arm of the display interferes with each other, the posture of the adjustment arm of the display is restricted, which limits the field of view of the display and reduces the doctor's user experience.
[0062] In view of at least one of the above problems, the embodiment of the present application provides an adjustment arm and a medical display assembly, which is provided with a first joint including a first assembly part, a second assembly part and a first connecting part, and the assembly seat for assembling the display is rotatably connected to the first assembly part, and the second assembly part is assembled with a camera. In this way, the camera and the display can be assembled on the same joint (first joint). Compared with the traditional technology, not only the number of adjustment arms is reduced, the structural complexity of the medical display assembly is reduced, but also when adjusting the display angle of the display, the adjustment arm of the display and the adjustment arm of the camera can be prevented from interfering with each other, ensuring that the field of view of the display is not affected, and improving the doctor's user experience.
[0063] First, refer to Figure 1 As shown, an embodiment of the present application provides an adjustment arm 11 , which can be used in a surgical robot or a medical display assembly 1 .
[0064] The adjusting arm 11 includes a joint group 111, a first joint 112 and an assembly seat 113. The first joint 112 is provided with a first assembly portion 1122, a second assembly portion 1123 and a first connecting portion 1124, and the first assembly portion 1122 and the second assembly portion 1123 are arranged at intervals from each other. The first connecting portion 1124 is rotatably connected to the joint group 111, and the second assembly portion 1123 is used to assemble the camera 13. The assembly seat 113 is rotatably connected to the first assembly portion 1122. The assembly seat 113 is used to assemble the display 12.
[0065] Here, it should be noted that the first assembly portion 1122 and the second assembly portion 1123 are arranged at intervals on the main structure of the first joint 112. By arranging the first assembly portion 1122 and the second assembly portion 1123 at intervals, after the display 12 and the camera 13 are assembled, it is possible to avoid interference between the two, for example, the camera 13 blocks the display screen of the display 12, or the display 12 blocks the line of sight of the camera 13.
[0066] It can be understood that the joint group 111 may include one joint or multiple joints.
[0067] In the embodiment of the present application, the first joint 112 can be equipped with both the display 12 and the camera 13, which is equivalent to combining the adjustment arm of the display 12 and the adjustment arm of the camera 13 into one. Compared with the traditional technology, not only the number of adjustment arms 11 is reduced, and the structural complexity of the medical display assembly 1 is reduced, but also when adjusting the display angle of the display 12, the adjustment arm of the display 12 and the adjustment arm of the camera 13 can be avoided from interfering with each other, thereby ensuring that the field of view of the display 12 is not affected, thereby improving the doctor's user experience.
[0068] It should be noted that in the traditional technology, reference Figure 1 As shown in the orientation, the camera 13 is usually arranged on the left or right side of the display 12. When the display 12 rotates to the left or right, the camera 13 and its adjustment arm will hinder the rotation of the display 12. Figure 1 As shown, the first connection portion 1124 of the first joint 112 is rotatably connected to the joint assembly 111, and the first joint 112 can rotate to the left or right. When adjusting the display angle of the display 12, when the display 12 is rotated to the left or right, since the display 12 and the camera 13 are assembled on the same joint, the display 12 and the camera 13 will rotate synchronously without interfering with each other.
[0069] In one embodiment, referring to Figure 1As shown, the first joint 112 includes a first connecting rod 1121, the first connecting rod 1121 has a first end and a second end arranged opposite to each other, and a first connecting portion 1124 is arranged at the first end. Among them, one end of the first assembly portion 1122 is connected to the first end, and the other end extends in a first direction away from the first end. One end of the second assembly portion 1123 is connected to the second end, and the other end extends in a first direction away from the second end. The first direction intersects with the length direction of the first connecting rod 1121. In this way, not only the structure of the first joint 112 is simple, but also the display 12 and the camera 13 can be prevented from interfering with each other in space.
[0070] In one example, the first direction is perpendicular to the length direction of the first link 1121 .
[0071] In one embodiment, the dimension of the first assembly portion 1122 along the first direction is smaller than the dimension of the second assembly portion 1123 along the first direction, that is, the length of the first assembly portion 1122 is smaller than the length of the second assembly portion 1123. In this way, after the display 12 and the camera 13 are assembled, the camera 13 can protrude from the display surface of the display 12 to prevent the display 12 from blocking the line of sight of the camera 13.
[0072] In one embodiment, referring to Figure 2 As shown, the joint assembly 111 includes a base 1111 and a second joint 1112. The second joint 1112 has a third end and a fourth end that are relatively arranged, the third end is rotatably connected to the base 1111, and the fourth end is rotatably connected to the first connection portion 1124. In this way, it is beneficial to increase the adjustable degree of freedom of the adjustment arm 11 or increase the adjustment range of the adjustment arm 11, thereby improving the doctor's use experience.
[0073] It is understandable that the second joint 1112 may be a lifting joint. The embodiment of the present application does not limit the type of the second joint 1112.
[0074] In one embodiment, referring to Figure 2 As shown, the base 1111 has a through cavity 1111a, and the second joint 1112 includes a second connecting rod 11121 and a second connecting shaft 11122 arranged on the second connecting rod 11121, and the second connecting shaft 11122 is rotatably arranged in the through cavity 1111a. Among them, the base 1111 is provided with a first damping mechanism 1113, and the first damping mechanism 1113 is in contact with the outer peripheral surface of the second connecting shaft 11122. By providing the first damping mechanism 1113, it is possible to avoid that the rotation gap between the second connecting shaft 11122 and the base 1111 is too large, so that the adjustment accuracy of the rotation angle of the second connecting shaft 11122 is higher.
[0075] In one example, the second connecting shaft 11122 and the second connecting rod 11121 may be connected via a second fastener 11125 .
[0076] In one example, the axial direction of the second connecting shaft 11122 is perpendicular to the length direction of the second connecting rod 11121 .
[0077] In one example, the second connecting shaft 11122 is a hollow shaft, so that wiring can be routed in the cavity of the second connecting shaft 11122, thereby hiding the wiring of the adjustment arm 11 and improving the appearance of the adjustment arm 11.
[0078] In one embodiment, referring to Figure 3 As shown, the first damping mechanism 1113 includes a first assembly shell 11131, a first assembly part 11132 and a first friction member 11133. A first assembly hole 1111b communicating with the through cavity 1111a is provided on the base 1111, and at least part of the structure of the first assembly shell 11131 is penetrated through the first assembly hole 1111b. A second assembly hole 11131a is provided on the side of the first assembly shell 11131 close to the through cavity 1111a. The first assembly part 11132 is provided in the first assembly hole 1111b, and illustratively, the first assembly part 11132 and the first assembly hole 1111b are shaft-hole matched. The first friction member 11133 is provided in the through cavity 1111a and is located between the first assembly part 11132 and the second connecting shaft 11122. It can be understood that the side of the first friction member 11133 close to the second connecting shaft 11122 contacts the second connecting shaft 11122.
[0079] Further, refer to Figure 4 As shown, a limiting structure 11134 is provided between the first assembly part 11132 and the hole wall of the second assembly hole 11131a, and the limiting structure 11134 is used to limit the radial movement of the first assembly part 11132 along the second assembly hole 11131a.
[0080] It should be noted that, in order to reduce the difficulty of assembling the first assembly part 11132 and the first assembly hole 1111b, the outer diameter of the first assembly part 11132 is usually smaller than the inner diameter of the first assembly hole 1111b, that is, after the first assembly part 11132 and the first assembly hole 1111b are assembled, there is a gap between the two. By setting the limiting structure 11134, when the display 12 is subjected to a large impact, when the second joint 1112 rotates around the base 1111, the first assembly part 11132 remains stationary along the radial direction of the second assembly hole 11131a, so that the first damping mechanism 1113 remains stationary, thereby eliminating the shaking of the display 12.
[0081] In one example, the first friction member 11133 is an oil-free bushing.
[0082] In one example, the limiting structure 11134 includes a protrusion 111341 and a groove 111342 that cooperate with each other, one of the protrusion 111341 and the groove 111342 is arranged on the hole wall of the first assembly hole 1111b, and the other is arranged on the first assembly part 11132.
[0083] In one embodiment, referring to Figure 3 As shown, the first assembly shell 11131 has a first accommodating chamber 11131b connected to the second assembly hole 11131a. The first damping mechanism 1113 also includes a first elastic member 11135 and a first adjusting member 11136, and the first elastic member 11135 is arranged in the first accommodating chamber 11131b. One end of the first elastic member 11135 abuts against the first assembly part 11132. The first adjusting member 11136 is arranged on the first assembly shell 11131, and at least part of the structure is located in the first accommodating chamber 11131b. The first adjusting member 11136 abuts against one end of the first elastic member 11135 away from the first assembly part 11132, and is used to adjust the elastic force of the first elastic member 11135.
[0084] In this way, by adjusting the compression amount of the first elastic member 11135 through the first adjusting member 11136, the friction force between the first friction member 11133 and the second connecting shaft 11122 can be adjusted, so that the friction force between the first friction member 11133 and the second connecting shaft 11122 can be linearly changed, so that the operating force between the second joint 1112 and the base 1111 can be linearly adjusted.
[0085] Exemplarily, the first elastic member 11135 may be a spring.
[0086] In one example, the first adjusting member 11136 includes a thrust portion (not shown) and an adjusting bolt (not shown), the thrust portion is located in the first accommodating cavity 11131b and abuts against the first elastic member 11135, and the adjusting bolt is passed through the first assembly shell 11131. By adjusting the length of the adjusting bolt extending into the first accommodating cavity 11131b, the friction force between the first friction member 11133 and the second connecting shaft 11122 can be adjusted.
[0087] In one embodiment, referring to Figure 2 As shown, a first rotating bearing 11141 is provided in the through cavity 1111a of the base 1111, and the second connecting shaft 11122 is passed through the first rotating bearing 11141. Furthermore, a first fastening nut 11142 is also assembled on the second connecting shaft 11122, and the first fastening nut 11142 is used to position the second connecting shaft 11122 in the axial direction.
[0088] In one example, the first rotary bearing 11141 is an angular contact ball bearing, so as to ensure that the axial clearance between the base 1111 and the second joint 1112 is uniform when the adjustment arm 11 is subjected to a large load.
[0089] In one embodiment, referring to Figure 5 As shown, the second connecting rod 11121 has an open cavity 11121a at one end away from the second connecting shaft 11122, and the first connecting portion 1124 is rotatably inserted into the open cavity 11121a. A protrusion 11121b is provided on the cavity wall of the open cavity 11121a. Along the insertion direction of the first connecting portion 1124, the opposite ends of the protrusion 11121b are provided with a first bearing member 11123, and the circumferential surface of the first connecting portion 1124 is in contact with the first bearing member 11123. Here, the insertion direction of the first connecting portion 1124 is the axial direction of the first connecting portion 1124. The above arrangement can simplify the connection structure between the first joint 112 and the second joint 1112, thereby reducing the manufacturing cost.
[0090] In one embodiment, the first bearing member 11123 is a bearing flange. It is understood that the bearing flange can be a standard part to ensure that the damping force does not decay and there is no wear noise during long-term operation.
[0091] In one embodiment, a first thrust assembly 11124 is provided on the side of the protrusion 11121b away from the opening of the open cavity 11121a. The first thrust assembly 11124 is assembled on the first connecting portion 1124 and abuts against the adjacent first bearing member 11123. The first thrust assembly 11124 is used to apply an elastic thrust force to the first bearing member 11123.
[0092] In one example, the first thrust assembly 11124 includes a second fastening nut (not shown), a second elastic member (not shown) and a thrust washer (not shown), wherein the thrust washer and the second elastic member are located between the second fastening nut and the first bearing member 11123, and the thrust washer is located between the second elastic member and the first bearing member 11123. The first connecting portion 1124 can be connected to the second connecting rod 11121 by setting the second fastening nut, the second fastening nut can be prevented from loosening by setting the thrust washer, and the friction torque can be linearly adjusted by setting the second elastic member to achieve linear adjustment of the operating force. Furthermore, when the first bearing member 11123 is worn, the first elastic member 11135 can adaptively compensate to ensure that the operating force does not change. Exemplarily, the second elastic member can be a disc spring.
[0093] In one embodiment, an elastic plunger 11126 is disposed on the cavity wall of the open cavity 11121a , and the elastic plunger 11126 is in contact with the first connecting portion 1124 to ensure electrical conduction between the first joint 112 and the second joint 1112 .
[0094] In one embodiment, the first assembly part 1122 includes an assembly plate 11221 and a sliding assembly 11222 disposed on the assembly plate 11221, and the sliding assembly 11222 forms a sliding track. The assembly seat 113 includes at least one sliding arm 1131, and the sliding arm 1131 is slidably assembled on the first assembly part 1122 along the sliding track. Exemplarily, the sliding arm 1131 is an arc-shaped structural member. In this way, by sliding the sliding arm 1131 on the sliding track, the pitch angle of the display 12 can be adjusted to enhance the doctor's user experience.
[0095] In one embodiment, referring to Figure 6 , Figure 7 and Figure 8 As shown, the sliding assembly 11222 includes a centering wheel 112221 and an eccentric wheel 112222 which are spaced apart in the hollow cavity, and the space between the centering wheel 112221 and the eccentric wheel 112222 constitutes a sliding track.
[0096] It should be noted that the centering wheel 112221 is a wheel structure with a constant rotation axis, while the eccentric wheel 112222 is a wheel structure with an adjustable rotation axis. By adjusting the rotation axis of the eccentric wheel 112222 relative to the centering wheel 112221, the gap space between the centering wheel 112221 and the eccentric wheel 112222 can be adjusted, which is suitable for assembling sliding arms 1131 of different sizes and structures. At the same time, considering the precision reasons such as manufacturing and assembly, there may be a gap after the sliding arm 1131 is assembled in the gap space between the centering wheel 112221 and the eccentric wheel 112222. Therefore, by adjusting the size of the gap space, the technical effect of compensating the gap can also be achieved, so as to achieve a shake-free assembly.
[0097] In one embodiment, a first blind hole 11221a is provided on the assembly plate 11221, and a part of the structure of the eccentric wheel 112222 is rotatably disposed in the first blind hole 11221a. The center line of the eccentric wheel 112222 is parallel to the center line of the first blind hole 11221a and does not overlap.
[0098] In one embodiment, a third assembly hole 11221b is provided at the bottom of the first blind hole 11221a, and the center line of the third assembly hole 11221b coincides with the center line of the first blind hole 11221a. The eccentric wheel 112222 includes an adjustment portion 1122221 and a wheel body 1122222 sleeved on a portion of the periphery of the adjustment portion 1122221, that is, a portion of the periphery of the adjustment portion 1122221 is not covered and exposed to the outside. The first assembly portion 1122 also includes a first fastener 11223, which passes through the adjustment portion 1122221 and is connected to the third assembly hole 11221b. In this way, the eccentric wheel 112222 can be assembled on the assembly plate 11221 by providing the first fastener 11223. By exposing part of the outer circumference of the adjusting part 1122221, the exposed outer circumference of the adjusting part 1122221 can be clamped with the help of a tool, and the adjusting part 1122221 can be rotated to adjust the positive pressure between the eccentric wheel 112222 and the sliding arm 1131, thereby achieving adjustable damping force.
[0099] In one embodiment, referring to Figure 6 and Fig.10 As shown, the first assembly portion 1122 further includes a second friction member 11224 and an elastic friction member 11225, wherein the second friction member 11224 is disposed on a side of the sliding arm 1131 close to the assembly plate 11221 and in contact with the sliding arm 1131, and the elastic friction member 11225 is disposed on a side of the sliding arm 1131 away from the assembly plate 11221 and in contact with the sliding arm 1131. In this way, the clearance of the sliding arm 1131 can be eliminated, thereby improving the assembly stability of the sliding arm 1131.
[0100] Exemplarily, the second friction member 11224 may be a friction plate, and the elastic friction member 11225 may be a spring plunger. It is understandable that there may be a plurality of elastic friction members 11225 to ensure that the sliding arm 1131 is not worn while eliminating the backlash.
[0101] In one embodiment, referring to Fig.11 As shown, a locking hole 1131a is provided on the sliding arm 1131, and an elastic clip 11226 is provided on the assembly plate 11221. The elastic clip 11226 and the locking hole 1131a are snap-fitted to achieve a locking effect, and the locking sound between the elastic clip 11226 and the locking hole 1131a can also be produced to serve as a reminder.
[0102] In one embodiment, the first connecting rod 1121 is connected to the first connecting portion 1124 via a third fastener 1125 .
[0103] Second, refer to Figure 1As shown, the embodiment of the present application further provides a medical display assembly 1, comprising a display 12, a camera 13 and an adjustment arm 11 as in any one of the first aspects. The display 12 is mounted on the mounting seat 113, and the camera 13 is mounted on the second mounting portion 1123.
[0104] The medical display assembly 1 provided in the embodiment of the present application is provided with a first joint 112 including a first assembly part 1122, a second assembly part 1123 and a first connecting part 1124, and the assembly seat 113 for assembling the display 12 is rotatably connected to the first assembly part 1122, and the second assembly part 1123 is assembled with the camera 13. In this way, the camera 13 and the display 12 can be assembled on the same joint (first joint 112). Compared with the traditional technology, not only the number of adjustment arms 11 is reduced, the structural complexity of the medical display assembly 1 is reduced, but also when adjusting the display angle of the display 12, the adjustment arm of the display 12 and the adjustment arm of the camera 13 can be avoided from interfering with each other, ensuring that the field of view of the display 12 is not affected, and improving the doctor's user experience.
