Detailed implementation manners

[0023] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] As mentioned in the background art, for the problem that in the prior art, the surgical support arm can only support the arm through a soft pad and cannot fix the patient's arm, and once the patient's arm shakes during the operation, it will affect the progress of the operation. The present invention provides a surgical support arm for surgical operations.

[0025] Embodiment 1

[0026] Referring to Figures 1 to 4 , a surgical support arm for surgical operations includes a base 1. An electric telescopic rod 2 is arranged on the top of the base 1. The output end of the electric telescopic rod 2 is connected to a mounting seat 3. The electric telescopic rod 2 is used to adjust the height of the support arm 7. A bidirectional electric guide rail 4 is arranged on the mounting seat 3. Sliding plates 5 are arranged at both ends of the bidirectional electric guide rail 4. The bidirectional electric guide rail 4 is used to adjust the distance between the support arms 7 on both sides;

[0027] Motors 6 are arranged on the tops of the sliding plates 5 on both sides. Support arms 7 are arranged on the output shafts of the motors 6. Soft pads 8 are arranged on the support arms 7. The motors 6 can drive the support arms 7 to rotate;

[0028] Slide rails 9 are arranged on both sides of the support arm 7. Convex cylinders 16 are evenly arranged on both sides of the support arm 7. The convex cylinders 16 protrude from both sides of the support arm 7 to facilitate the alignment of the subsequent insertion rods 17;

[0029] The support arm 7 is slidably connected to two identical carriages 10 through the slide rails 9;

[0030] Pressing components and positioning components are arranged on both of the two carriages 10;

[0031] The positioning components are inserted into the convex cylinders 16.

[0032] The pressing component includes a screw rod 11 and a guide rod 12 that vertically penetrate through the carriage 10. The bottom of the screw rod 11 is connected with a pressing ring 13 through a bearing, and the guide rod 12 is connected with the pressing ring 13. A hand wheel 15 is arranged at the top of the screw rod 11. A pressing pad 14 is arranged at the bottom of the pressing ring 13. By rotating the hand wheel 15, under the guidance of the guide rod 12, the pressing ring 13 drives the pressing pad 14 to move vertically downward, and thus the arm supported on the soft pad 8 can be fixed.

[0033] In order to enable the pressing ring 13 to press at different positions, a positioning component is provided so that the position of the carriage 10 can be adjusted. The positioning component includes two identical plug rods 17. The two plug rods 17 are respectively inserted into two convex cylinders 16. Connecting plates 18 are arranged at the mutually remote ends of the two plug rods 17. Moving rods 19 are arranged on the two connecting plates 18. A sliding groove 20 is arranged on the front side of the carriage 10, and the moving rods 19 are slidably connected in the sliding groove 20.

[0034] A rotating shaft 21 is connected to the sliding groove 20 through a bearing. Threads 22 are arranged on both sides of the rotating shaft 21. The helix directions of the threads 22 on both sides are opposite, and the moving rods 19 on both sides are respectively screwed on the threads 22 on both sides. By rotating the rotating shaft 21, the threads 22 on both sides drive the moving rods 19 on both sides to move in opposite directions, so that the connecting plates 18 can drive the plug rods 17 to move horizontally, and thus the plug rods 17 can be inserted into the convex cylinders 16 or separated from them.

[0035] Embodiment 2

[0036] Referring to Figures 3 to 4 , in order to facilitate the rotation of the rotating shaft 21, a driven bevel gear 23 is arranged on the rotating shaft 21. A driving bevel gear 24 is meshed with the driven bevel gear 23. A support shaft 25 is arranged on the driving bevel gear 24. The support shaft 25 is connected to the carriage 10 through a bearing. A knob 26 is arranged at the top of the support shaft 25, and the knob 26 is arranged above the carriage 10 for easy rotation, so that the support shaft 25 drives the driving bevel gear 24 to rotate, and then drives the driven bevel gear 23 to rotate, so that the rotating shaft 21 rotates.

[0037] The rest of the structure is the same as that of Embodiment 1.

[0038] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
