DETAILED DESCRIPTION

[0025] The present invention is described below in conjunction with the accompanying drawings. The specific implementation methods described herein are only used to illustrate and explain the present invention and are not used to limit the present invention. Without departing from the design spirit of the present invention, various modifications and improvements made to the technical solution of the present invention by ordinary technicians in this field should fall within the protection scope of the present invention.

[0026] like Figures 1 to 9 As shown, the arm support frame of this embodiment includes a clamp 1, a fixing rod 2, a support rod 3, a connecting rod 4 and a support plate 5.

[0027] The clamp 1 is used to clamp on the foot 501 of the operating bed 50. The clamp 1 of this embodiment includes a fixing ring 11, a connecting plate 12, a bolt 13 and a nut 14. The fixing ring 11 is elastic and is provided with two. The rear end faces of the two fixing rings 11 are provided with openings, and screw holes are provided on both sides of the openings. The two fixing rings 11 are both equipped with bolts 13 and nuts 14. The bolts 13 are inserted from the screw holes on one side of the openings and connected to the nuts 14 after passing through the screw holes on the other side of the openings. The two fixing rings 11 are arranged at intervals up and down, and the two fixing rings 11 are connected by a connecting plate 12. The connecting plate 12 is opposite to the opening of the fixing ring 11. The upper end of the connecting plate 12 is connected to the lower end face of the upper fixing ring 11, and the lower end of the connecting plate 12 is connected to the upper end face of the lower fixing ring 11. When in use, the two fixing rings 11 are elastically inserted into the foot 501 of the operating bed 50 through the openings at the rear ends thereof, and then the fixing rings 11 are fastened to the foot 501 by tightening the nuts 14, so that the clamp 1 is installed and clamped on the foot 501, and the front end of the fixing rings 11 faces outward. By loosening the nuts 14 on the two fixing rings 11, the two fixing rings 11 can be moved on the foot 501 at the same time under the action of the connecting plate 12 and adjusted to a suitable position.

[0028] One end of the fixed rod 2 is fixedly connected to the lower side wall of the clamp 1, specifically, the end of the fixed rod 2 is connected to the front end surface of the fixed ring 11 located below. The other end of the fixed rod 2 is rotatably connected to the lower end of the support rod 3, and the rotational connection is specifically as follows: a fixed block 6, a driving gear 7 and a driven gear 8 are arranged between the end of the support rod 3 and the end of the fixed rod 2, wherein two fixed blocks 6 are provided, and the two fixed blocks 6 are arranged at intervals at the end of the fixed rod 2. The driving gear 7 and the driven gear 8 are arranged between the two fixed blocks 6, and the driving gear 7 is meshed and connected with the driven gear 8 and is located above the driven gear 8. The two sides of the driving gear 7 and the driven gear 8 are hinged to the side walls of the two fixed blocks 6 respectively. The end of the support rod 3 is fixedly connected to the upper end of the driving gear 7. The end of the support rod 3 can rotate along the axis of the hinge shaft where the driving gear 7 and the fixed block 6 are hinged. The rotation of the driving gear 7 will drive the driven gear 8 to rotate. At this time, the damping formed by the meshing connection between the driving gear 7 and the driven gear 8 can reduce the noise generated when the support rod 3 rotates.

[0029] The connecting rod 4 is a telescopic rod, one end of which is hinged to the upper side wall of the clamp 1, specifically to the front end face of the fixing ring 11 located above, and the other end of the connecting rod 4 is hinged to the side wall of the support rod 3. An adjusting screw for adjusting its length is provided on the side wall of the connecting rod 4.

[0030] The support plate 5 is arranged at the upper end of the support rod 3 for placing the doctor's arm. A support column 9 is arranged between the support rod 3 and the support plate 5. The support column 9 is a telescopic rod, and the side wall of the support column 9 is provided with an adjustment screw for adjusting its length, so that the arm of the support plate 5 can be changed as needed.

[0031] By adjusting the length of the connecting rod 4, the inclination angle of the support plate 5 can be changed to provide the doctor with different angles of supporting the arm. When the length of the connecting rod 4 is shortened, the support rod 3 will rotate toward the direction close to the clamp 1. At this time, the angle between the support rod 3 and the fixed rod 2 becomes smaller, and the angle between the support rod 3 and the connecting rod 4 becomes larger. At this time, the support plate 5 tilts toward one side of the clamp 1; when the length of the connecting rod 4 is extended, the support rod 3 will rotate away from the clamp 1. At this time, the angle between the support rod 3 and the fixed rod 2 becomes larger, and the angle between the support rod 3 and the connecting rod 4 becomes smaller. At this time, the support plate 5 tilts toward the side away from the clamp 1.

[0032] A fixed plate 10 is provided at the upper end of the support column 9, and a sliding plate 20 is provided below the support plate 5. The sliding plate 20 is located above the fixed plate 10, and the two sides below the sliding plate 20 are slidably connected to the two sides of the fixed plate 10. In this way, the support plate 5 can be moved along the length direction of the fixed plate 10 as needed, so that the part of the support plate 5 located at the left end of the support column 9 is longer or the part of the support plate 5 located at the right end of the support column 9 is longer. When the clamp 1 is fixed to the bed foot 501 on the left side of the operating bed 50, if the support plate 5 is far away from the middle of the operating bed 50 and it is inconvenient to support the left arm, the support plate 5 can be moved to the right along the fixed plate 10.

[0033] In order to fix the position of the support plate 5 after it moves, a plurality of first protrusions 101 are arranged at intervals on both sides of the fixed plate 10 along its length direction, and the edges of the first protrusions 101 are arc-shaped. A plurality of second protrusions 201 are arranged at intervals on both sides of the lower side of the sliding plate 20 along its length direction, and the edges of the second protrusions 201 are arc-shaped. The first protrusions 101 and the second protrusions 201 are interlaced and clamped together. The first protrusion 101 and the second protrusion 201 both have a certain elasticity. The length of the sliding plate 20 of this embodiment is shorter than the length of the fixed plate 10. Therefore, the number of the second protrusions 201 is less than the number of the first protrusions 101. In the overlapped part of the sliding plate 20 and the fixed plate 10, the second protrusion 201 will be stuck between two adjacent first protrusions 101. Relatively, the first protrusion 101 will also be stuck between two adjacent second protrusions 201. When pushing the sliding plate 20 to slide, it takes a certain amount of effort to make the second protrusion 201 move from between the current two adjacent first protrusions 101 to between the next two adjacent first protrusions 101 after elastic compression. Although there will be a certain friction resistance when pushing the sliding plate 20 to move, after moving, the second protrusion 201 on the sliding plate 20 will be stuck between the adjacent first protrusions 101, and can fix the position after moving. At the same time, the first protrusion 101 and the second protrusion 201 will not protrude outward too much, reducing the resistance when pushing. In actual use, the support plate 5 is pushed to move, and the support plate 5 and the sliding plate 20 are connected together.

[0034] In this embodiment, a through hole 202 is provided in the middle of the upper plate surface of the sliding plate 20, and a rotating column 51 is provided in the middle of the lower plate surface of the support plate 5. The rotating column 51 is inserted into the through hole 202, and the support plate 5 can be horizontally rotated around the axis of the through hole 202, so that the support plate 5 can rotate in the horizontal direction, which is not limited to the doctor's arm being placed in only one direction.

[0035] In addition, the upper plate surface of the sliding plate 20 is provided with a plurality of slots 203 around the through hole 202. The lower plate surface of the support plate 5 is provided with a placement slot 52 located beside the rotating column 51. The placement slot 52 can correspond to the position of any slot 203. A marble 30 and a spring 40 are provided in the placement slot 52. One end of the spring 40 is connected to the bottom of the placement slot 52, and the other end is connected to the marble 30. After the support plate 5 rotates, the marble 30 can be elastically ejected into the slot 203 corresponding to its position. For example, 12 slots 203 are provided on the sliding plate 20, and the angles formed between adjacent slots 203 are the same. The placement slot 52 of the support plate 5 initially corresponds to the first slot 203. At this time, the marble 30 is stuck in the first slot 203. Then, when the support plate 5 is rotated, the marble 30 will continuously move into the placement slot 52 under the pressure of the side wall of the first slot 203 and the spring 40 will be continuously compressed until it completely enters the placement slot 52. When it moves to the second slot 203, the marble 30 will be ejected and stuck in the second slot 203 under the action of the spring 40. The same principle applies to rotating to the third slot 203. In this way, not only the support plate 5 can be rotated, but also the position of the support plate 5 after rotation can be fixed. However, there is a certain friction resistance when rotating the support plate 5, and a certain amount of effort is required.

[0036] Since the position of the sliding plate 20 does not need to be changed during the horizontal rotation of the support plate 5 , the horizontal rotation and horizontal movement of the support plate 5 do not interfere with each other.

[0037] When the present invention is in use, the clamp 1 is fixed on the foot 501 of the operating bed 50, and can be fixed on the foot 501 at the end of the operating bed 50, and the support plate 5 is located at the end of the operating bed 50. During the operation, the doctor can place his arm on the support plate 5 so that the arm can be supported, which can effectively reduce the fatigue of the arm; during use, the length of the connecting rod 4 can be adjusted as needed, and the support plate 5 can be tilted toward the side close to the clamp 1 or toward the side away from the clamp 1, which can provide the doctor with a comfortable support angle, and the height of the support column 9 can be adjusted. At the same time, the support plate 5 can be moved horizontally and rotated horizontally, giving the doctor a more comfortable support position to meet more surgical needs, and has strong applicability.
