[0039] It should be noted that, without conflict, the embodiments and features in the embodiments of this application can be combined with each other. The present invention will be described in detail below with reference to the drawings and in combination with the embodiments.

[0040] For the convenience of understanding and description, the following description of the present invention adopts an absolute positional relationship. Without special explanation, the orientation word "upper" represents Figure 1 the upper side direction in Figure 1 the orientation word "lower" represents Figure 1 the lower side direction in Figure 1 the orientation word "left" represents Figure 1 the left side direction in Figure 1The present invention is described from the perspective of the reader or user, but the above-mentioned directional terms should not be understood or interpreted as limiting the scope of protection of the present invention. The dimensions and angles of the components herein can be determined by those skilled in the art based on actual needs or limited experiments.

[0041] like Figures 1 to 3 、 Figure 12 As shown, an operating bed clamping device according to an embodiment of the present invention includes a left guide rail matching mechanism 1, a connecting crossbeam 2 and a right guide rail matching mechanism 3 connected in sequence from left to right, the left guide rail matching mechanism 1, the connecting crossbeam 2 and the right guide rail matching mechanism 3 form a bed board matching groove 4, the left guide rail matching mechanism 1 and / or the right guide rail matching mechanism 3 contain a guide rail locking mechanism 5, the bed board 61 of the operating bed 6 can be installed in the bed board matching groove 4, the operating bed clamping device can move along the guide rails 62 on the left and right sides of the bed board 61, and the guide rail locking mechanism 5 can lock the operating bed clamping device and the guide rails 62 of the operating bed 6.

[0042] The left guide rail mating mechanism 1 is capable of coupling and mating with the guide rail 62 on the left side of the bed plate 61, and the right guide rail mating mechanism 3 is capable of coupling and mating with the guide rail 62 on the right side of the bed plate 61. The left guide rail mating mechanism 1 includes a guide rail locking mechanism 5, or the right guide rail mating mechanism 3 includes a guide rail locking mechanism 5, or both the left guide rail mating mechanism 1 and the right guide rail mating mechanism 3 include a guide rail locking mechanism 5. After the guide rail locking mechanism 5 locks the guide rail 62 of the operating bed clamping device and the operating bed 6, the operating bed clamping device and the operating bed 6 are connected and fixed as one, preventing relative movement between the operating bed clamping device and the operating bed 6.

[0043] For example, Figure 4 and Figure 7 As shown, the right guide rail engagement mechanism 3 includes a guide rail locking mechanism 5. This mechanism not only locks the operating table clamping device and the guide rail 62 of the operating table 6, but also engages with the guide rail 62 on the right side of the bed plate 61. The right guide rail engagement mechanism 3 also includes a right mounting base 31. The guide rail locking mechanism 5 is connected to the right mounting base 31 via a right lifting mechanism 32. The right lifting mechanism 32 enables the guide rail locking mechanism 5 to move up and down relative to the right mounting base 31.

[0044] like Figures 8 to 11As shown, the guide rail locking mechanism 5 includes a locking shell 51, in which a push plate 52, an upper pressing block 53, a lower pressing block 54 and a right roller 58 are arranged. The upper pressing block 53, the push plate 52 and the lower pressing block 54 are connected in sequence to form a guide rail mounting groove 55, and the guide rail 62 on the right side of the bed board 61 can be matched and inserted into the guide rail mounting groove 55. A clamping handle 56 is provided outside the locking shell 51, and the clamping handle 56 includes a circular segment 561 and a bar segment 562 connected in sequence. The clamping handle 56 is connected to the locking shell 51 through a clamping shaft 57. When the bar segment 562 rotates downward from a horizontal state to an upright state, the circular segment 561 can push the push plate 52 to move in a direction away from the clamping shaft 57, and the push plate 52 can make the upper pressing block 53 move downward and the lower pressing block 54 move upward. The upper pressing block 53 and the lower pressing block 54 can clamp and fix the guide rail 62 of the operating bed 6.

[0045] Specifically, the clamping handle 56 is located on the right side of the locking housing 51. The clamping handle 56 includes a circular segment 561 and a strip segment 562 connected in sequence. The axis of the circular segment 561 and the axis of the clamping shaft 57 both extend in the front-to-back direction. The clamping shaft 57 passes through the circular segment 561. The clamping handle 56 can rotate around the clamping shaft 57. The axis of the clamping shaft 57 deviates from the axis of the circular segment 561, that is, the circular segment 561 has an eccentric wheel structure. The locking housing 51 is provided with a pressing hole 511. The position of the pressing hole 511 corresponds to the position of the circular segment 561. The outer circumference of the circular segment 561 can pass through the pressing hole 511 of the locking housing 51 to abut against the push plate 52. The upper clamping block 53 is mated with the upper portion of the push plate 52, and the lower clamping block 54 is mated with the lower portion of the push plate 52. The contact surfaces of the push plate 52 with the upper and lower clamping blocks 53 and 54 are all inclined surfaces.

[0046] like Figures 8 to 11 As shown, when the bar segment 562 rotates downward from the horizontal position to the upright position, the circular segment 561 pushes the push plate 52 away from the clamping shaft 57. The push plate 52 causes the upper clamping block 53 to move downward and the lower clamping block 54 to move upward. This reduces the distance between the upper and lower clamping blocks 53, 54, allowing them to clamp and secure the guide rail 62 of the operating bed 6. At this point, the guide rail locking mechanism 5 is in the locked state, locking the operating bed clamping device and the guide rail 62 of the operating bed 6. To unlock, when the bar segment 562 is rotated upward from the upright position to the horizontal position, the upper and lower clamping blocks 53, 54 are no longer able to clamp and secure the guide rail 62 of the operating bed 6, and the guide rail locking mechanism 5 is in the unlocked state.

[0047] The clamping handle 56 is also connected to a spring plunger 59, which includes a pin 591 and a spring 592. The pin 591 can move axially, and the spring 592 can reset the pin 591, thereby locking the clamping handle 56 and the locking housing 51. The lower end of the locking housing 51 is provided with a socket for the pin 591. When the bar segment 562 is rotated downward from the horizontal state to the upright state, the pin 591 is inserted into the socket at the lower end of the locking housing 51, and the clamping handle 56 can no longer rotate, so that the guide rail locking mechanism 5 can remain locked.

[0048] When the guide rail locking mechanism 5 needs to be unlocked, the pin 591 is first pulled out of the insertion hole of the locking housing 51, and the clamping handle 56 of the guide rail locking mechanism 5 can be rotated. The guide rail locking mechanism 5 can be implemented by rotating the clamping handle 56 as described above. Alternatively, the guide rail locking mechanism 5 can be implemented by using a locking bolt. For example, the locking housing 51 can be provided with a locking bolt that is threadedly connected to the locking housing 51. When the locking bolt is tightened, the rear end of the locking bolt abuts against the guide rail 62, and the guide rail locking mechanism 5 can lock the operating table clamping device and the guide rail 62 of the operating table 6. Loosening the locking bolt releases the lock.

[0049] like Figure 7 As shown, the right mounting seat 31 includes a front column 311, an upper beam 312 and a rear column 313 connected in sequence from front to back, a right through hole 314 is provided on the upper beam 312, and the axis of the right through hole 314 extends in the up and down direction, and the right lifting mechanism 32 includes a right adjusting screw 321, a right lead screw 322 and a right nut 323 connected in sequence from top to bottom, the right lead screw 322 is in an upright state, the upper end of the right lead screw 322 is located in the right through hole 314, the right nut 323 is connected and fixed to the guide rail locking mechanism 5, and the guide rail locking mechanism 5 and the right mounting seat 31 are also connected by a slide rail. During the process of screwing the right adjusting screw 321, the guide rail locking mechanism 5 moves up and down relative to the right mounting seat 31.

[0050] like Figure 4 and Figure 6 As shown, the connecting crossbeam 2 includes left and right width adjustment mechanisms 21 and a surgical equipment mounting platform 22. The width adjustment mechanism 21 can adjust the distance between the left guide rail mating mechanism 1 and the right guide rail mating mechanism 3. Surgical equipment can be mounted on the surgical equipment mounting platform 22. The left end of the width adjustment mechanism 21 is bolted to the left guide rail mating mechanism 1. The width adjustment mechanism 21 is bolted to the surgical equipment mounting platform 22. The surgical equipment mounting platform 22 is also bolted to the right mounting seat 31.

[0051] The width adjustment mechanism 21 includes a fixed frame 211, a movable rod 212, a transverse screw 213 and an upper nut 214. A first left adjustment through hole 215 is provided at the left end of the fixed frame 211. The fixed frame 211, the movable rod 212 and the transverse screw 213 all extend in the left and right directions. The transverse screw 213, the upper nut 214 and the movable rod 212 are connected in sequence. The left side of the transverse screw 213 passes through the first left adjustment through hole 215. The left end of the transverse screw 213 is coaxially connected with a first left adjusting screw 216. During the process of screwing the first left adjusting screw 216, the movable rod 212 can move left and right, and the size of the width adjustment mechanism 21 along the left and right directions can be adjusted.

[0052] like Figure 6 As shown, the fixed frame 211 includes a front frame rod 217, a left frame rod 218, and a rear frame rod 219, which are connected in sequence from front to back. The front frame rod 217 and the rear frame rod 219 both extend in the left-right direction and are spaced apart from each other. The movable rod 212 is located between the front frame rod 217 and the rear frame rod 219, and the first left adjustment hole 215 is located in the left frame rod 218. The movable rod 212 and the fixed frame 211 are also connected by a slide rail. The left frame rod 218 is connected to the left guide rail matching mechanism 1 by bolts.

[0053] The surgical equipment mounting table 22 includes a supporting plate 221, and docking optical axes 222 are provided in front and rear of the supporting plate 221. Supporting wheels 223 are connected to the bottom of the supporting plate 221. The supporting wheels 223 are used to support the operating bed clamping device. The two docking optical axes 222 extend in the left and right directions. The supporting plate 221 and the right end of the movable rod 212 are connected in an upper and lower stack by bolts. The axis of the supporting wheel 223 extends in the left and right direction, and the supporting wheel 223 can abut against the upper surface of the bed plate 61 of the operating bed 6.

[0054] like Figure 7 As shown, the supporting plate 221 is a generally rectangular plate parallel to the horizontal plane. Two docking optical axes 222 are connected to the supporting plate 221 via optical axis seats 224. Along the left-right direction, the docking optical axes 222 are longer than the supporting plate 221, and the docking optical axes 222 and the supporting plate 221 are substantially at the same height. A mounting groove is provided within the supporting plate 221, within which a spirit level 225 is mounted. The spirit level 225 can be a conventional bubble level.

[0055] like Figure 5As shown, the left guide rail engagement mechanism 1 includes a left housing 11, which is an upright plate-like structure. A left roller 13 and a left bearing 14 are disposed on the right side of the left housing 11. The outer circumference of the left roller 13 is capable of contacting the outer side surface of the guide rail 62, and the outer circumference of the left bearing 14 is capable of contacting the lower end surface of the guide rail 62. A second left adjustment hole 12 is disposed at the top of the left housing 11. The axis of the second left adjustment hole 12 extends in the left-right direction, and the left end of the transverse lead screw 213 is located in the second left adjustment hole 12.

[0056] The left guide rail matching mechanism 1 also includes a bearing lifting assembly 15, which includes a second left adjusting screw 151, a left lead screw 152 and a left nut 153 connected in sequence from top to bottom. The left lead screw 152 is in an upright state, and a nut mounting cavity 111 is provided at the lower portion of the left shell body 11. A second left adjusting through hole 112 is provided at the upper portion of the left shell body 11. The nut mounting cavity 111 and the second left adjusting through hole 112 are connected, and the axis of the second left adjusting through hole 112 extends in the up and down directions. The left nut 153 is located in the nut mounting cavity 111, and the left nut 153 and the left shell body 11 are connected by a sliding rail. The left bearing 14 is connected to the left nut 153 through a rotating shaft. The upper portion of the left lead screw 152 is located in the second left adjusting through hole 112. During the process of screwing the second left adjusting screw 151, the left nut 153 can move up and down.

[0057] The working process of the operating table clamping device is described below.

[0058] like Figures 1 to 3 、 Figure 12 As shown, the operating bed clamping device is installed on the operating bed 6, that is, the bed plate 61 is located in the bed plate mating groove 4. By turning the second left adjustment screw 151, the left nut 153 can be moved up and down, and the left roller 13 and left bearing 14 can be matched and fitted with the guide rail 62 on the left side of the operating bed 6. By turning the first left adjustment screw 216, the width adjustment mechanism 21 can be adjusted in the left-right direction, and the distance between the left guide rail mating mechanism 1 and the right guide rail mating mechanism 3 can be adjusted. By turning the right adjustment screw 321, the guide rail locking mechanism 5 moves up and down relative to each other, and the right roller 58 can be matched and fitted with the guide rail 62 on the right side of the operating bed 6. Guide rails 62 are provided on both the left and right sides of the bed plate 61, and the guide rails 62 on the left and right sides are mirror images of each other.

[0059] First, with the guide rail locking mechanism 5 in the unlocked state, the operating table clamping device is moved forward and backward along the guide rail 62 of the operating table 6 to the desired position. The bar-shaped segment 562 of the clamping handle 56 is rotated downward from the horizontal state to the upright state. The upper clamping block 53 and the lower clamping block 54 clamp and fix the guide rail 62 of the operating table 6. The pin 591 of the spring plunger 59 is inserted into the socket at the lower end of the locking housing 51. The clamping handle 56 can no longer be rotated, and the guide rail locking mechanism 5 remains locked. The operating table clamping device and the operating table 6 are connected and fixed as one body, and the two cannot move relative to each other (the reverse operation can unlock the guide rail locking mechanism 5). At this time, surgical equipment (such as an interventional surgical robot) can be installed on the surgical equipment mounting table 22.

[0060] The above description is merely a specific embodiment of the present invention and is not intended to limit the scope of the invention. Therefore, substitutions of equivalent components, or equivalent changes and modifications made within the scope of protection of the present invention, should still fall within the scope of the present invention.
