The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0041] like Figure 1 , Figure 2 As shown, the surgical robot includes a main operation console 1 and a slave operation device 2. The main operation console 1 is used to send control commands to the slave operation device 2 according to the doctor's operation to control the slave operation device 2, and is also used to display the image obtained by the slave device 2. The slave operation device 2 is used to respond to the control command sent by the main operation console 1 and perform corresponding operations, and the slave operation device 2 is also used to obtain images in the body.

[0042] The slave operation device 2 includes a mechanical arm 21, a power mechanism 22 disposed on the mechanical arm 21, a surgical instrument 23 disposed on the power mechanism 22, and a sleeve 24 for sleeves of the surgical instrument 23. The mechanical arm 21 is used to adjust the position of the surgical instrument 23; the power mechanism 22 is used to drive the surgical instrument 23 to perform corresponding operations, and the power mechanism has a mounting housing, which is connected to the mechanical arm and can move relative to the mechanical arm; the surgical instrument 23 is used to extend into the body and perform surgical operations and / or obtain in-body images through its distal end instrument. Among them, the mechanical arm 21 has a base 201, and the base 201 has a supporting device 10 to move and support the mechanical arm 21.

[0043] like Figures 3 to 5 As shown, the support device 10 includes: a main body 100, and a moving mechanism 200 and a lifting mechanism 300 both arranged on the main body 100. The moving mechanism 200 is used to move and / or support the object to be supported, and the lifting mechanism 300 is used to support the object to be supported moved by the moving mechanism 200, so as to support the object to be supported independently or in cooperation with the moving mechanism 200. In this embodiment, the support device 10 is used to support and move itself, that is, the moving mechanism 200 of the support device 10 is used to abut against a supporting surface such as the ground to move the support device 10 and be supported by the support device 10. In other embodiments, the support device 10 can also support and move other objects to be supported arranged on the support device 10, that is, at this time the support device 10 is fixed, and the object to be supported placed thereon is moved by the moving mechanism 200.

[0044] The moving mechanism 200 may have a variety of structures. In the present embodiment, the moving mechanism 200 is a moving wheel, and there are multiple moving wheels, which are distributed along the periphery of the main body 100. The moving mechanism 200 has a moving surface. When the moving mechanism 200 is used to move the supporting device 10, the moving surface is the ground or the supporting surface supporting the moving mechanism 200. When the moving mechanism 200 is used to move the object to be supported placed thereon, the moving surface is the contact surface between the moving mechanism 200 and the object to be supported that it moves. In other embodiments, the moving mechanism 200 may also be a belt transmission mechanism, etc. The moving wheels may also be evenly distributed on the periphery of the object to be supported that it moves.

[0045] In one embodiment, the mobile mechanism 200 has a locking device for stopping the movement of the mobile mechanism 200. The locking device can be locked and released by the host and / or manually. When the locking device is locked by the host, the mobile device has a power structure to drive the mobile mechanism 200 to move.

[0046] In one embodiment, there are multiple lifting mechanisms 300, which are evenly distributed along the object they support. For example, when the lifting mechanisms 300 support the main body, they are distributed along the periphery of the main body. Furthermore, the lifting mechanisms 300 are located in the area surrounded by the moving mechanism 200 to make the movement more stable. In this case, the lifting mechanisms 300 can be arranged near the moving mechanism 200 to make the support more stable. In this embodiment, there are four lifting mechanisms 300, which are distributed in a rectangular shape.

[0047] like Figure 3 to Figure 4 As shown, the lifting mechanism 300 has a power unit 310, a lifting unit 320, and a brake unit 330 and a reset unit 340 connected to the lifting unit 320. The power unit 310 is used to drive the lifting unit 320 to move up and down; the lifting unit 320 moves along the direction toward or away from the moving surface of the moving mechanism 200, so that it can support or release the object to be supported by the moving mechanism 200; the brake unit 330 is used to lock the lifting unit 320 when triggered to fix it in the current position. In this embodiment, the brake unit 330 is connected to the lifting unit 320 through the power unit 310 to brake the lifting unit 320; when the power unit is powered off, after the brake unit 330 is manually released, the reset unit 340 can provide elastic force to drive the lifting unit 320 to move in the direction of releasing the supported object to be supported, so that the reset unit 340 can release the supported object to be supported. In this way, the reset part can reset the lifting part in various states. For example, after the power part 310 is powered off, the support device 10 can reset the lifting part 320, and then move the object to be supported again through the moving mechanism 200, thereby improving the reliability and ease of use of the support device 10. For another example, the reset part can also assist in resetting the lifting part. It should be noted that in other embodiments, the power part can also be omitted, and the lifting part can be moved by other means, such as manually.

[0048] In one embodiment, the lifting part 320 has a lifting body 323 and a support member 322, and the transmission assembly 321 includes a synchronous belt structure 321A, a driven wheel 321B and a driving wheel (not shown in the figure), the driving wheel is connected to the power part 310, the driven wheel 321B is connected to the lifting body lead screw 323, the driving wheel and the driven wheel 321B are connected through the synchronous belt structure 321A, the lifting body lead screw 323 is connected to the support member 322, and the support member 322 is used to support the object to be supported. In other embodiments, the transmission assembly 321 can also be other structures, for example, the transmission assembly 321 is a gear rack assembly. In this embodiment, the lifting body is a lead screw, and in some other embodiments, the lifting body can also be other mechanical structures that can achieve lifting. The brake part 330 and the power part 310 are respectively located on the upper and lower sides of the body 100, the transmission assembly 321 and the lifting mechanism 300 are respectively located on the upper and lower sides of the body, and the transmission assembly 321 is located between the body 100 and the brake part 330.

[0049] In one embodiment, the power unit 310 obtains the supporting pressure on the supporting surface of the lifting unit through electric current. When the supporting pressure reaches a preset value, the power unit 310 stops driving and the braking unit 330 is triggered to fix the lifting unit 320 at the current position. In this embodiment, the preset value of the supporting pressure is less than the pressure of the object to be supported, that is, the lifting unit 320 and the moving unit jointly support the object to be supported. For example, the sum of the preset pressures of multiple lifting units 320 is half of the pressure of the object to be supported. In other embodiments, the preset value of the supporting pressure may also be the same as the pressure of the object to be supported, that is, the supported object is supported only by the lifting unit 320. It should be noted that when there are multiple lifting units 320, the preset values ​​of the supporting pressures of the multiple lifting units 320 may be the same or different.

[0050] In one embodiment, the brake part 330 has a manual switch and a brake device, the brake device is used to brake the power part 310, and the manual switch is used to manually release the brake part 330 after the power part 310 is powered off. In other embodiments, the brake part 330 can also be released by the power part 310. At this time, the power part 310 can be powered off after releasing the brake part 330, or the power part 310 is in an unlocked state, so as to move the lifting part 320 through the reset part 340, or after releasing the brake part 330, the lifting part 320 is moved by the electric part. It should be noted that the brake part can also be released when the power part is not powered off to stop the power part.

[0051] In one embodiment, the brake device may not include a manual switch. In this case, after the support member runs to a predetermined position (for example, the support member supports the support surface), the brake device of the brake part energizes the brake part so that the brake part brakes the power part and locks the power part. When the power part is powered off, the brake part is also powered off so that the brake device of the brake part releases the power part, and the reset part moves the lifting part to reset it.

[0052] In other examples, the braking part may also be arranged on one side of the lifting part, while no braking part is arranged on the side of the power part, and the braking part brakes and releases the lifting part.

[0053] like Figure 3 and Figure 5 As shown, the manual switch includes a pedal 331, and a pivoting portion 333 is provided inside the pedal 331. The pedal 331 is rotatably connected to a connecting bracket 334 on the main body 100 through the pivoting portion 333. The brake portion 330 also includes an unlocking mechanism 335 for manually releasing the brake portion 330. The unlocking mechanism 335 includes a U-shaped clip 3352 and an operating rod 3351. One end of the operating rod 3351 is fixedly connected to the U-shaped clip 3352, and the other end is a free end. The unlocking mechanism 335 is pivotally connected to the brake device of the brake portion 330 through the U-shaped clip 3352.

[0054] The left and right sides of the pedal 331 are respectively provided with pressing members 336, the lower end of the pressing member 336 is fixedly connected to the pedal 331, and the upper end is rotatably connected to a pressing roller 377. When the brake part 330 needs to be manually released, the pedal 331 is stepped on, and the pedal 331 drives the pressing member 336 to rotate relative to the main body 100 through the pivot part 333. As the rotation amplitude of the pedal 331 increases, the pressing roller 337 at the upper end of the pressing member 336 gradually presses the operating rod 3351 of the unlocking mechanism 335. The pressing roller 337 can roll on the operating rod 3351 to reduce the friction between the pressing member 336 and the operating rod 3351. The operating rod 3351 drives the U-shaped clip 3352 to rotate relative to the brake part 330, so that the unlocking mechanism 335 performs manual release of the brake part 330. During the entire manual release process, the pedal 331 and the unlocking mechanism 335 always rotate around the same rotation axis D1. The inner side of the pedal 331 is connected to the main body 100 through a spring 338, and a baffle 332 is provided on the outer side of the spring 338. When the manual release is completed, the pedal 331 is released, and the pedal 331 automatically returns to the initial position under the action of the spring 338. In some other embodiments, the unlocking mechanism 335 may also only include an operating rod 3351, and the operating rod 3351 is directly connected to the brake device of the brake part 330. After the pressing member 336 of the pedal 331 presses the operating rod 3351, the operating rod 3351 directly executes the unlocking of the brake device of the brake part 330.

[0055] In one embodiment, the reset portion 340 includes a bracket 341 and an elastic member 342. The bracket 341 is disposed on the lifting portion 320 and moves with the lifting portion 320. The two ends of the elastic member 342 respectively abut the bracket 341 and the main body to drive the bracket 341 to move through the elastic force, thereby driving the lifting portion 320 to release the supported object to be supported.

[0056] In one embodiment, if Figure 7 As shown, there is one elastic member 352, which is sleeved on the lifting part 320, one end of the elastic member 354 abuts against the bracket 351, and the other end abuts on the mounting seat of the lifting part. In some other embodiments, there are three elastic members 352, two of which are respectively located on both sides of the lifting part 320, and the other is sleeved on the lifting part 320.

[0057] In one embodiment, if Figure 8 As shown, there is one elastic member 442, and the two ends of the elastic member 442 respectively abut against the bracket 441 and the main body. The lifting part 420 includes a supporting member 422 and a lifting body 423. The lifting body 423 is provided with a guide member 451, and the guide member 451 is fixed to the main body through a fixed bracket 452. Compared with the above two embodiments, this embodiment uses a guide member 451 instead of the guide column 351, so that the height of the lifting part 420 can be made higher.

[0058] The lifting mechanism 300 is further provided with a guide part 350. In this embodiment, the guide part 350 includes a guide column 351 and a linear bearing 352 sleeved on the guide column, wherein the guide column 351 is connected to the bracket 341, the linear bearing 352 is connected to the main body 100, and the reset part 340 sleeves the guide column 351, and the guide column 351 moves with the bracket 341. In other embodiments, the guide part can also be other structures, for example, the guide part includes a guide column and a moving part movably arranged on the guide column, a guide groove is opened on the guide column, and the moving groove moves along the guide groove, and in this case, the reset part sleeves the guide column.

[0059] A sensing piece 345 is provided on the bracket 341, and a distance measuring column 343 is provided on the main body 100. A proximity sensor 344 is provided at the free end of the distance measuring column, and the proximity sensor 344 can sense the sensing piece 345. During the rising process of the lifting mechanism 300, the sensing piece 345 rises together with the bracket 343. When the proximity sensor 344 detects that the sensing piece 345 reaches a predetermined position, the lifting mechanism 300 stops rising. Figure 6 In the illustrated embodiment, there are two guide parts 350, which are respectively located on both sides of the lifting part 320, and the first guide part and the second guide part are symmetrically arranged, and the first guide part, the second guide part, the lifting body and the distance measuring column are parallel to each other. At this time, the guide part 350 is arranged near the end of the lifting part 320 that is not used for support. In other embodiments, there can also be one guide part 350, or other numbers.

[0060] like Fig. 9 In the illustrated embodiment, the support device 10 further includes a dust cover 400, which is sleeved on the lifting part 320, and one end of which is connected to the end of the lifting part 320. The dust cover wraps the lifting part 320 to expose the main body to prevent dust, and the other end of the dust cover can be arranged on the main body. Among them, when the lifting part 320 is located on one side of the main body, the dust cover wraps it at this time; when the lifting part 320 is arranged on both sides of the main body through the main body, the dust cover covers the exposed part of the lifting part 320. Further, the dust cover 400 has a telescopic main body 100, which can be telescoped between the lifting part 320 and the main body as the lifting part 320 is raised and lowered. It should be noted that in other embodiments, the dust cover can also be omitted.

[0061] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0062] The above-mentioned embodiments only express several implementation methods of the present invention, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the invention patent. It should be pointed out that, for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention.
