Description

Technical Field

[0001] The present invention relates to the technical field of neurosurgery arm brackets, in particular to a neurosurgery arm bracket device. Background Art

[0002] The neurosurgery arm support is an auxiliary tool designed specifically for neurosurgery. The use of this arm support can help doctors maintain the correct surgical posture, reduce fatigue of the arms, shoulders and neck, and thus improve the accuracy and safety of the operation.

[0003] The current arm support is mainly composed of a base, a hydraulic rod and a cross plate. The hydraulic rod is connected to the top of the base, and its top is fixedly connected to the cross plate. The cross plate is used to place the arm, and the hydraulic rod is used to drive the cross plate to rise and fall, so as to achieve the function of adjusting the height. However, this adjustment method is usually adjusted quickly, and there is no buffer time. This rapid adjustment is prone to over-adjustment and cannot accurately adjust to the appropriate height. At the same time, when the doctor is using it, the adjustment speed is too fast and the doctor has no time to react. This can easily cause the doctor to lose support in a short time, causing the doctor's body to shake to a certain extent, and the sitting posture needs to be readjusted later. In severe cases, the body shaking may cause the doctor to make operational errors, and there are certain safety hazards. Therefore, an arm support device for neurosurgery is designed to solve the problem that the doctor cannot accurately adjust to the appropriate height due to over-adjustment, and in severe cases, the doctor has no time to react due to the adjustment speed. This may cause the doctor to make operational errors due to body shaking, and there are certain safety hazards. Summary of the invention

[0036] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0037] refer to Figure 1 - Figure 8 The embodiment of the present invention provides an arm support device for neurosurgery, including a support base 1, a lifting seat 2, a connecting frame 3 and a protective bottom cover 35. A sliding guide rail 4 is provided on the top of the support base 1, and the sliding guide rail 4 runs through the support base 1. The top and bottom of the sliding guide rail 4 are set to be narrower, and the middle is set to be wider. At the same time, a sliding support rod 5 is slidably connected to the inside of the sliding guide rail 4. One end of the sliding support rod 5 is rotatably connected to the surface of the lifting seat 2, and the end of the sliding support rod 5 away from the lifting seat 2 is rotatably connected to a sliding wheel 6. The surface of the sliding wheel 6 is rollingly connected to the inner wall of the sliding guide rail 4. When the sliding support rod 5 slides inside the sliding guide rail 4, it can drive the sliding wheel 6 to roll on the inner wall of the sliding guide rail 4. Therefore, the provision of the sliding wheel 6 can improve the smoothness of the sliding of the sliding support rod 5.

[0038] like Figure 3 , Figure 4 , Figure 7 and Figure 8As shown, a circular cavity 7 is provided at the bottom of the support base 1, and a large gear 8 and a transmission gear 9 are provided inside the circular cavity 7. Both the large gear 8 and the transmission gear 9 rotate at the top of the inner wall of the circular cavity 7. Four transmission gears 9 are provided and are evenly arranged on the surface circumference of the large gear 8. The cavity shaft for transmission is provided at the support base 1 and is located at the bottom of the circular cavity 7, and a gear shaft is fixed on the top of the large gear 8 and the transmission gear 9. The cavity shaft and the gear shaft are vertically arranged, and the gear shaft rotates inside the cavity shaft. The large gear 8 and the transmission gear 9 rotate with the top of the inner wall of the circular cavity 7 through the gear shaft. The surface of the large gear 8 and the surface of the transmission gear 9 are meshed with each other, and the large gear 8 drives the transmission gear 9 to start rotating after the rotation. The bottom of the inner wall of the sliding guide 4 is slidably connected to the transmission rack 10, one side of the transmission rack 10 passes through the sliding guide 4 and extends to the inside of the circular cavity 7, and the surface of the transmission rack 10 located inside the circular cavity 7 is meshed with the surface of the transmission gear 9, and the large gear 8 drives the transmission rack 10 to move along the sliding guide 4 after the rotation.

[0039] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, a driving rack 10 is fixedly connected to a pushing link 11 on one side away from the driving gear 9, and an end of the pushing link 11 away from the driving rack 10 is fixedly connected to a limiting slide 12, and both sides of the limiting slide 12 are slidably connected to the inner wall of the sliding guide rail 4, and a damper 13 is fixedly connected to the top of one side of the limiting slide 12, and an end of the damper 13 away from the limiting slide 12 is fixedly connected to an arc-shaped card plate 14, and the bottom of the arc-shaped card plate 14 is slidably connected to the inside of the sliding guide rail 4, and a side of the arc-shaped card plate 14 away from the damper 13 abuts against an end of the sliding support rod 5 located inside the sliding guide rail 4, and the driving rack 10 can drive the pushing link 11 to move after it moves, and the movement of the pushing link 11 drives the limiting The slide plate 12 moves, and then the limiting slide plate 12 drives the damper 13 and the arc-shaped card plate 14 to slide inside the sliding guide rail 4. After the arc-shaped card plate 14 moves, it squeezes the sliding support rod 5, so that the sliding support rod 5 slides inside the sliding guide rail 4, and the sliding support rod 5 is adjusted. The lifting seat 2 is then lifted to achieve the height adjustment. This adjustment method can slowly lift and lower to avoid over-adjustment and can be accurately adjusted. At the same time, this slow adjustment is combined with the damper 13 to buffer during adjustment, avoiding shaking of the doctor due to adjustment during use, reducing the possibility of operational errors, and thus ensuring the safety of adjustment of the arm bracket during use.

[0040] like Figure 4 , Figure 7 , Fig.12 and Fig.13As shown, the shape of the transmission gear 9 is set to be an I-shaped, and a sliding sleeve 41 is sleeved in the middle of the transmission gear 9. The top and bottom ends of the I-shaped transmission gear 9 are provided with teeth, and the middle part is smooth, and the sliding sleeve 41 is sleeved on this smooth part. The transmission gear 9 rotates inside the sliding sleeve 41, and a sliding rod 42 is fixedly connected to one side of the bottom of the sliding sleeve 41. The surface of the sliding rod 42 is slidably connected to the surface of the protective bottom cover 35. The protective bottom cover 35 is provided with a rail, so that the sliding rod 42 can slide in the protective bottom cover 35 through the rail. The sliding rod 42 is placed vertically, and the bottom end of the sliding rod 42 passes through the protective bottom cover 35 and extends to the bottom of the protective bottom cover 35. The bottom of the protective bottom cover 35 is fixedly connected with an adjusting slot bin 43. The surface of the adjusting slot bin 43 is rotatably connected with an adjusting screw rod 44. The surface of the adjusting screw rod 44 is threadedly connected with the surface of the sliding rod 42. When adjusting, the adjusting screw rod 44 is rotated. After the adjusting screw rod 44 rotates, it drives the sliding rod 42 to slide in the adjusting slot bin 43, thereby driving the sliding sleeve 41 to move. The sliding sleeve 41 can pull the transmission gear 9 to move, so that the transmission gear 9 can be disengaged from the large gear 8 and the transmission rack 10. The rack 10 loses its limit, and the transmission rack 10 at this location no longer moves, which also makes the transmission rack 10 here not make the sliding support rod 5 slide inside the sliding guide rail 4, which causes one corner of the lifting seat 2 not to be lifted. At the same time, the corner is pressed by the arm, which will cause the lifting seat 2 to form an angle tilt. When it tilts to a certain degree, the adjusting screw rod 44 can be rotated in the reverse direction to drive the transmission gear 9 to approach the transmission rack 10 and the large gear 8. At this time, the transmission rack 10 is restricted again. After being pressed by the arm, the lifting seat 2 will not continue to form an inclination angle, thereby achieving the function of adjusting the inclination of a single angle, further improving the adaptability of use.

The orientation of the teeth of the four transmission racks 10 is set to the counterclockwise direction. The orientation of the teeth of the transmission racks 10 is set to the counterclockwise direction. In this way, in conjunction with the four transmission gears 9, the transmission racks 10 on both sides of the large gear 8 can move in opposite directions, thereby driving the sliding struts 5 on both sides of the lifting seat 2 to shrink or open toward the middle, thereby adjusting the height of the lifting seat 2. The heights of the four transmission gears 9 are all higher than the height of the large gear 8, and the height of the transmission gear 9 is higher than the height of the large gear 8. The transmission rack 10 is attached to the bottom of the large gear 8, so that the transmission gear 9 can drive the transmission rack 10 to move while being driven by the large gear 8. The top of the lifting seat 2 is rotatably connected with an elastic padded pressure plate 15, and the elastic padded pressure plate 15 is used to support the doctor's arm. When the doctor's arm is placed on the elastic padded pressure plate 15, the elastic padded pressure plate 15 will be pressed down to cause it to undergo elastic deformation, thereby increasing a certain degree of softness and improving the applicability and comfort of the arm bracket.
