Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a multi-purpose retractable medical hand support frame. Background Art

[0002] When doctors are performing surgery, they often need to put patients in various required positions, which require arm support, especially in the side-lying position. If the upper arm is not well supported, it will not only affect the doctor's surgery, but also the function of the patient's hand. The hand support currently used is double-layered, with a fixed and rigid placement, complicated operation, and unable to adjust the patient's arm to various angles according to the patient's body shape. There are also single-board types on the market, but they cannot be adjusted according to the actual needs of the patient. In addition, when doctors perform laparoscopic surgery, the assistants who hold the lens have their arms suspended in the air without support. The longer the operation time, the more sore and numb the assistant's arms become, and it is difficult to maintain the stability of the lens, thus affecting the operation and progress of the surgeon. Therefore, in order to meet the needs of patients or doctors during surgery, it is necessary to design a lightweight and easy-to-install hand support. Utility Model Content

[0017] The utility model is described in detail below with reference to the accompanying drawings:

[0018] In the description of the present utility model, it should be noted that the directions or positional relationships indicated by "upper", "lower", "top" and "bottom" are based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the utility model product is usually placed when in use. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, and a specific direction structure and operation, and therefore cannot be understood as a limitation on the present utility model.

[0019] like Figure 1-5As shown, a multi-purpose retractable medical arm rest comprises a support plate 1, a slide rail 2, a pulley 3, a support plate 4, a locking device 5, a fixed L-shaped bracket 6 and a movable L-shaped bracket 7. The support plate 4 is arranged directly below the support plate 1, and the length of the support plate 4 is half of the length of the support plate 1, and the width is the same. A slide rail 2 and a pulley 3 are arranged between the support plate 4 and the support plate 1. A slide rail 2 is arranged on each side of the bottom of the support plate 1, and the length of the slide rail 2 is two-thirds of the length of the support plate 1 to ensure the range of movement of the extension and retraction of the support plate 1; the pulley 3 is slidably arranged in the slide rail 2 and fixedly connected to the support plate 4, and the pulley 3 is composed of a base 31 and a wheel 32. Four wheels 32 are arranged side by side on the base 31, and the wheels 32 are slidably arranged in the slide rail 2. Under the restriction of the slide rail 2, the wheels 32 move horizontally along the slide rail 2. The pulley 3 is provided with a locking device 5, which includes a hand screw 51, a spring 52 and a locking block 53. A groove 33 for installing the locking block 53 is provided on the base 31. The width of the locking block 53 is smaller than the width of the slide groove on the slide rail 2. When not in the locked state, the locking block 53 can move in the slide groove of the slide rail 2 as the base 31 moves. The hand screw 51 passes through the side of the base 31 and is rotatably connected to the locking block 53. The hand screw 51 is threadedly connected to the base 31. The spring 52 is arranged between the hand screw 51 and the base 31. The function of the spring 52 is to increase a pre-tightening force on the hand screw 51 to ensure that it will not loosen. When locking is required, the hand screw 51 is turned to adjust the locking block 53 to squeeze and contact with the slide rail 2 to generate friction to achieve locking.

[0020] The horizontal section of the fixed L-shaped bracket 6 is fixedly connected to the bottom of the support plate 4, and the horizontal section of the fixed L-shaped bracket 6 is a hollow structure, and the horizontal section of the movable L-shaped bracket 7 is inserted into the horizontal section of the fixed L-shaped bracket 6. The movable L-shaped bracket 7 is a movable additional component. When providing a hand support for a patient, the movable L-shaped bracket is not needed, because the patient's hand does not need to move after being placed, and the stability requirement is not strict, only a supporting effect is needed, and one bracket is sufficient for support; when providing a hand support for a doctor, the movable L-shaped bracket 7 needs to be installed, because when the doctor performs the mirror holding operation, the hand is pressed on the center of the support plate, and the hand holding the mirror will move the position of the arm as the surgical field changes. If the arm support is not stable enough, the operation will also be shaken, thereby affecting the operation of the operation, so the stability requirement for the support plate 1 is relatively strict, and at this time, both sides of the support plate 1 need to be supported to keep the support plate 1 stable.

[0021] In order to provide a comfortable placement for the user's hands, a soft cushion is provided on the top surface of the support plate 1 .

[0022] The working principle of the utility model is as follows: when using it on patients, use a conventional lock to pass through the fixed L-shaped bracket 6 to adjust the height and direction and fix it on the side bar of the operating bed, and then adjust the inner and outer distances of the support plate 1 according to the different needs of the patients. The support plate 1 is placed to the outside of the operating bed, which is suitable for supporting the upper arm in the lateral position. The support plate 1 is placed to the inside of the operating bed, which is suitable for supporting the opposite arm when the supine position is raised and recovered. When used for hand support during laparoscopic surgery, use a conventional lock to pass through the fixed L-shaped bracket 6 to adjust the height and then place the support plate 1 vertically to the inside of the operating bed and fix it on the side bar of the operating bed, and the movable L-shaped bracket 7 is inserted into the horizontal section of the fixed L-shaped bracket 6 and fixed to the side bar of the operating bed in parallel with the fixed L-shaped bracket 6 to ensure the stability of the hand support, so that the hand support will not shake when the doctor supports the hand.

[0023] Although the specific embodiments of the present invention have been described and illustrated in detail above, it should be noted that various changes and modifications may be made to the above embodiments without departing from the spirit of the present invention and the scope of the appended claims.
