Description

Technical Field

[0001] The present application relates to the field of medical equipment, and in particular to a support mechanism for surgical equipment and the surgical equipment. Background Art

[0002] Larger surgical equipment usually has rollers at the bottom to facilitate the movement of the surgical equipment. Existing surgical equipment usually needs to be pushed by manpower. Some surgical equipment needs to be moved to a specific position during surgery. For example, C-arms are often used for intraoperative X-ray fluoroscopy. When the C-arm is positioned clinically, in order to find a suitable fluoroscopic position, the position of the C-arm needs to be adjusted multiple times and X-ray fluoroscopy needs to be performed. The positioning of the C-arm is not only time-consuming and laborious, but multiple X-ray fluoroscopy also increases the radiation dose received by doctors and patients. Utility Model Content

[0039] The following is a clear and complete description of the technical solution of the present application in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0040] like Figure 1 As shown, an embodiment of the present application provides a surgical device, which includes a device body 100 and a support mechanism 200 of the surgical device. The device body 100 is disposed on the support mechanism 200, and the support mechanism 200 can drive the device body 100 to move.

[0041] like Figure 2 As shown, the support mechanism 200 includes: a chassis 1, a driving wheel assembly bracket 2, at least two driving wheel assemblies 3 and a universal wheel 4.

[0042] The device body 100 is arranged on the top surface of the chassis 1. The driving wheel assembly bracket 2 is arranged on the chassis 1. Optionally, the driving wheel assembly bracket 2 and the chassis 1 are fastened and connected by screws. The two ends of the driving wheel assembly bracket 2 are respectively located on the outer sides of the corresponding side walls of the chassis 1.

[0043] At least two driving wheel assemblies 3 are respectively disposed at both ends of the driving wheel assembly bracket 2. For example, there are two driving wheel assemblies 3. The driving wheel assembly 3 has the ability to move forward, backward and turn to drive the chassis 1 forward, backward or turn.

[0044] The universal wheels 4 are arranged on the bottom surface of the chassis 1. The universal wheels 4 follow the driving wheel assembly 3 to move forward, backward or turn, so that the support mechanism 200 can move at any angle. The number of universal wheels 4 is set according to demand.

[0045] The driving wheel controller 5 is in communication connection with the driving wheel assembly 3. The driving wheel controller 5 is used to control the driving wheel assembly 3 to perform corresponding actions. For example, the surgical equipment stores a map of the operating room, and the operator inputs the location where the surgical equipment needs to be placed in the surgical equipment. The controller of the surgical equipment plans the moving path according to the current location of the surgical equipment and the location where it needs to be placed, and sends the moving path to the driving wheel controller 5. The driving wheel controller 5 controls the driving wheel assembly 3 to perform corresponding actions to move the surgical equipment to the placement position. Figure 2 The dashed lines in the figure represent communication connections.

[0046] Optionally, the driving wheel controller 5 is disposed on the device body 100 .

[0047] In this embodiment, the driving wheel assembly 3 drives the surgical device to move, avoiding manual pushing of the surgical device and saving manpower. The surgical device can move to a designated position according to the planned moving path, facilitating accurate positioning of the surgical device and saving operation time.

[0048] like Figure 3 As shown, in some embodiments, the driving wheel assembly includes: a driving wheel frame 31 , a driving wheel 32 , a steering assembly 33 and a travel drive 34 .

[0049] The driving wheel frame 31 is rotatably disposed on the driving wheel assembly bracket 2. For example, the driving wheel frame 31 includes a rotating shaft. The driving wheel frame 31 is rotatably connected to the driving wheel assembly bracket 2 and supports the driving wheel assembly bracket 2. The driving wheel frame 31 can rotate around a vertical axis.

[0050] The driving wheel 32 is rotatably disposed on the driving wheel frame 31 . The driving wheel 32 is in contact with the ground and can rotate around an axis in the horizontal direction.

[0051] The steering assembly 33 is used to drive the driving wheel frame 31 to rotate. The rotation of the driving wheel frame 31 can adjust the travel direction of the driving wheel frame 31 .

[0052] The travel driver 34 is disposed on the driving wheel frame 31, and the output end of the travel driver 34 is connected to the driving wheel 32 for driving the driving wheel 32 to rotate. Optionally, the travel driver 34 is a servo motor, which can provide feedback on the rotation speed and number of rotations of the driving wheel 32 to determine the travel speed and displacement of the driving wheel 32.

[0053] For example, according to the moving path, the surgical equipment needs to move forward 1m and then move 1m to the left. The workflow is:

[0054] The driving wheel controller 5 controls the driving wheels 32 of the two driving wheel assemblies 3 to move forward at the same speed, and the surgical device moves forward by 1 m;

[0055] The driving wheel controller 5 controls the steering components 33 of the two driving wheel assemblies 3 to work, so that the driving wheel frames 31 of the two driving wheel assemblies 3 are both rotated 90° to the left;

[0056] like Figure 4 As shown, in some embodiments, the steering assembly 33 includes: a steering driver 331 , a first gear 332 , and a second gear 333 .

[0057] The steering driver 331 is disposed on the driving wheel assembly bracket 2. The first gear 332 is disposed at the output end of the steering driver 331, for example, the first gear 332 is located below the driving wheel assembly bracket 2. The second gear 333 is disposed on the driving wheel frame 31, and the second gear 333 is adapted to the first gear 332. Optionally, the steering driver 331 is a servo motor, which can provide feedback on the rotation angle of the driving wheel frame 31.

[0058] For example, when the surgical device needs to turn, the driving wheel controller 5 controls the steering drivers 331 of the two driving wheel assemblies 3 to operate, and respectively rotates the two driving wheel frames 31 to a preset angle. The driving wheel controller 5 controls the driving wheels 32 of the two driving wheel assemblies 3 to move forward at different speeds to achieve the turning of the surgical device. Optionally, the preset angles of rotation of the two driving wheel frames 31 can be different, and the specific preset angles are set according to requirements.

[0059] In some embodiments, the driving wheel assembly 3 further includes a bearing 35. Figure 4 and Figure 5 As shown, the driving wheel assembly bracket 2 is provided with a large diameter hole 21 and a small diameter hole 22 which are interconnected, and the large diameter hole 21 is located above the small diameter hole 22. A bearing 35 is arranged in the large diameter hole 21. A pressure cover 36 is threadedly connected to the hole wall of the large diameter hole 21, and the bearing 35 is pressed by the method on the bearing 35. The rotating shaft of the driving wheel frame 31 is connected to the bearing 35, so that the driving wheel frame 31 can rotate relative to the driving wheel assembly bracket 2.

[0060] like Figure 6As shown, the driving wheel frame 31 includes: a frame body 311 and a rotating shaft 312. The frame body 311 is in an inverted U shape, the driving wheel 32 is rotatably arranged on the frame body 311, and the travel driver 34 is arranged on the frame body 311.

[0061] The rotating shaft 312 is arranged at the top end of the frame body 311. The rotating shaft 312 is a stepped shaft, comprising a large diameter portion 3121 and a small diameter portion 3122 connected to each other. The small diameter portion 3122 is installed in the inner ring of the bearing 35. The diameter of the large diameter portion 3121 is larger than the diameter of the small diameter hole 22 of the driving wheel assembly bracket 2, and the large diameter portion 3121 is used to support the driving wheel assembly bracket 2.

[0062] like Figure 4 As shown, optionally, a nut 37 is provided at the top end of the small diameter portion 3122 , and the nut 37 locks the small diameter portion 3122 and the inner ring of the bearing 35 .

[0063] like Figure 6 As shown, in some embodiments, the driving wheel assembly 3 further includes a wear pad 38, which is disposed on the shoulder of the rotating shaft 312. The wear pad 38 abuts against the driving wheel assembly bracket 2 to prevent the driving wheel assembly bracket 2 from directly rubbing against the large diameter portion 3121.

[0064] In some embodiments, the surface of the driving wheel 32 is provided with anti-skid grooves (not shown in the figure) to facilitate the movement of the driving wheel 32.

[0065] In some embodiments, the universal wheels 4 are located at the ends of the chassis 1 to provide stable support for the chassis 1 .

[0066] The surgical device of this embodiment is driven to move by the driving wheel 32. The rotation of the driving wheel frame 31 can change the traveling direction of the driving wheel 32, so that the surgical device can be quickly moved to a designated position.
