Abstract
Description
Technical Field
[0001] The utility model relates to the field of hand supports for surgery, and specifically to a hand support for surgery. Background Technique
[0002] During surgery, the arm will be suspended, which is rather strenuous and likely to cause soreness, affecting the operation. Currently, hand supports are often used to support the arm. However, the current hand supports are manually adjusted in height, which is inconvenient to use. There are also a few electric ones, but when adjusting up and down, it is easy to get confused, that is, the up and down height switches are prone to accidentally touch each other. Therefore, how to achieve the electric adjustment of the hand support and avoid reverse accidental touch is an urgent problem for those skilled in the art. Content of the Utility Model
[0003] The purpose of the utility model is to provide a hand support for surgery to solve the problems raised in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solution: A hand support for surgery, including a bottom shell with an open upper end, a support cylinder installed in the bottom shell, a telescopic rod inserted in the support cylinder, and an arm support plate installed at the upper end of the telescopic rod. The support cylinder can be fixed to the bottom shell through connecting plates arranged around it. It also includes an electric push rod arranged in the bottom shell, and the electric push rod is connected to the lower end of the telescopic rod to achieve electric telescoping. A foot switch is installed in the bottom shell, which drives the electric push rod to contract downward when stepped on, and a kick switch is arranged on the support cylinder, which drives the electric push rod to extend when kicked upward. Place the foot between the foot switch and the kick switch, so that when stepping on, the height of the support plate decreases, and when kicking upward, the support plate rises. One goes down and the other goes up, making it not easy to accidentally touch.
[0005] Preferably, the foot switch includes a pedal installed in the bottom shell and adapted to it, and the pedal is connected to the bottom of the inner cavity of the bottom shell through an elastic component. A push-button reverse switch for controlling the reverse rotation of the electric push rod is installed at the bottom of the inner cavity of the bottom shell.
[0006] Preferably, the elastic component is a spring, and the spring can make the pedal more stable.
[0007] Preferably, a circumferentially inwardly extending annular placement plate for supporting the foot is formed at the upper end of the bottom shell. It is convenient to place the foot, and when the pedal needs to be stepped on, the tip of the toe can be used to press down, so that the foot will not accidentally touch when placed flat.
[0008] Preferably, the upward kick switch includes a sliding cylinder sleeved on the support cylinder, and an annular kick plate is circumferentially fixed to the upper end of the sliding cylinder. A push-button forward rotation switch for controlling the forward rotation of the electric push rod is installed on the support cylinder above the kick plate. When the foot is placed normally, it will not touch the kick plate. When kicking upward, the kick plate will contact the forward rotation switch, the electric push rod will extend, and the support plate will rise for height adjustment. When the foot is released, the rising stops.
[0009] Preferably, the circumference of the kick plate slopes upward to avoid hurting the leg.
[0010] Preferably, a mis-touch prevention gap is left between the kick plate and the forward rotation switch to avoid mis-touch, and a spring for buffering can also be added.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows: When the foot is placed on the placement plate and it is desired to lower the height of the support plate, step on the pedal. The pedal presses the reverse rotation switch on the lower side, so that the electric push rod contracts and the height is reduced. When adjusting the support plate to a higher level, kick the kick plate upward to achieve elevation. Here, stepping on the foot is used for lowering, and kicking upward is used for rising. The two directions are different and mis-touch will not occur. BRIEF DESCRIPTION OF THE DRAWINGS

[0016] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.
[0017] Please refer to Figures 1 to 3, the present utility model provides a technical solution for a hand support for surgery: A hand support for surgery includes a bottom shell 1 with an open upper end, a support cylinder 2 installed in the bottom shell 1, a telescopic rod 3 inserted into the support cylinder 2, and an arm support plate 4 installed at the upper end of the telescopic rod 3. The support cylinder 2 can be fixed to the bottom shell 1 through connecting plates arranged around it. It also includes an electric push rod 5 arranged in the bottom shell 1, and the electric push rod 5 is connected to the lower end of the telescopic rod 3 to achieve electric telescoping. A foot switch is installed in the bottom shell 1, which drives the electric push rod 5 to contract downward when stepped on, and a kick switch is arranged on the support cylinder 2, which drives the electric push rod 5 to extend when kicked upward. The feet are placed between the foot switch and the kick switch, so that when stepping on, the height of the support plate 4 decreases, and when kicking upward, the support plate 4 rises. One goes down and the other goes up, making it not easy to be accidentally touched.
[0018] The foot switch includes a pedal 6 installed in the bottom shell 1 in a matching manner, and the pedal 6 is connected to the bottom of the inner cavity of the bottom shell 1 through an elastic member. A push-button reverse switch 7 for controlling the reverse rotation of the electric push rod 5 is installed at the bottom of the inner cavity of the bottom shell 1. The elastic member is a spring 8, and the spring 8 can make the pedal 6 more stable. A circumferentially inwardly extending annular placement plate 9 for supporting the feet is formed at the upper end of the bottom shell 1. It is convenient to place the feet. When the pedal 6 needs to be stepped on, the toes can be used to press down, so that the feet will not be accidentally touched when placed flat.
[0019] The kick switch includes a sliding cylinder 10 sleeved on the support cylinder 2, and a circumferentially fixed annular kick plate 11 is fixed at the upper end of the sliding cylinder 10. A push-button forward switch 12 for controlling the forward rotation of the electric push rod 5 is installed on the support cylinder 2 above the kick plate 11. During normal foot placement, the kick plate 11 will not be touched. When kicking upward, the kick plate 11 will contact the forward switch 12, the electric push rod 5 will extend, and the support plate 4 will rise for height adjustment. When the foot is released, the rising stops. The circumference of the kick plate 11 slopes upward to avoid pressing against the leg. A non-accidental touch gap is left between the kick plate 11 and the forward switch 12 to avoid accidental touch, and a spring 8 for increasing buffering can also be added.
[0020] Working principle: When the feet are placed on the placement plate 9 and it is desired to lower the height of the support plate 4, step on the pedal 6. The pedal 6 presses the reverse switch 7 below, so that the electric push rod 5 contracts and the height decreases. When adjusting the support plate 4 to a higher level, kick the kick plate 11 upward to achieve elevation. Here, the downward movement is controlled by stepping on the foot, and the upward movement is achieved by kicking. The two directions are different and accidental touch will not occur.
[0021] Although the embodiments of the present utility model 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 principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
