Description

Technical Field

[0001] The utility model relates to the technical field of lifting and fixing frames, in particular to an upper limb lifting and fixing frame. Background Art

[0002] In long-term clinical work, CT examinations have been widely used in medical services. At present, CT scanning beds are equipped with head frames, which are very convenient for head scans. When examining various parts of the body below the neck, both hands need to be raised from both sides of the body over the head. At this time, people will place their hands on both sides of the head frame for parallel support.

[0003] However, using this method to lift the upper limbs has the following defects: First, the existing head frame is a structure for supporting the head, and there is no structure on both sides to support the upper limbs. Even if some head frames are wider or additionally equipped with supporting structures, they still cannot move. When the examination bed is moving for scanning, the patient's hands will move slightly with the movement of the examination bed, which can easily cause movement artifacts in the scanning area and affect the image quality; secondly, for patients with limited upper lifting due to periarthritis of the shoulder and patients with limb weakness due to stroke, the existing bracket cannot comfortably and efficiently support such patients, which not only affects the patient's comfort, but also causes the problem of scanning failure. Therefore, it is urgently needed to be improved. Utility Model Content

[0004] The purpose of the utility model is to provide an upper limb lifting and fixing frame to solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above utility model purpose, the utility model adopts the following technical solutions:

[0006] The utility model provides an upper limb lifting fixing frame, comprising:

[0007] A binding assembly, wherein two binding assemblies are provided and are used to fix the wrists of both hands of the patient respectively;

[0008] A supporting component, wherein two supporting components are provided and correspond one to one with the binding components respectively;

[0017] Preferably, a guide rod is also fixed between the two support plates, and the guide rod penetrates through the two moving plates and is slidably sleeved with the moving plates.

[0018] Preferably, the supporting component includes a U-shaped plate, and a threaded rod is threadedly connected to one side of the U-shaped plate. One end of the threaded rod penetrates through the U-shaped plate and is rotatably connected to a clamping plate, and a friction lining is arranged on the side of the clamping plate away from the threaded rod.

[0019] Preferably, a plurality of jacks are provided on the side of the U-shaped plate away from the threaded rod. Positioning plates are provided on the opposite sides of the two connecting plates through springs, and an insertion rod penetrating through the connecting plate is fixed to the end of the positioning plate facing the spring. The insertion rod and the jack are matched with each other.

[0020] Compared with the prior art, the above one or more technical solutions have the following beneficial effects:

[0021] 1. The entire device can be installed on the testing bed through the support component, and then the relative distance between the two binding components can be adjusted through the adjustment component, so as to facilitate the use of different patients; in addition, the binding belt in the binding component can cooperate with the recessed part, so that the patient's wrist can be placed in the recessed part and bound by the binding belt, so as to facilitate the fixation of the hands of stroke patients or frozen shoulder patients and improve the accuracy of subsequent scanning detection;

Therefore, when the handle is turned, the worm rotates, so that the worm wheel is driven, and then the rotating shaft drives the winding roller to rotate, so as to adjust the tightness of the binding belt. Moreover, due to the one-way self-locking property between the worm wheel and the worm, the worm can drive the worm wheel to rotate, but the worm wheel cannot make the worm rotate. Therefore, after the adjustment is completed by rotating the worm, the entire binding belt can be self-locked, without the need to additionally set up a locking structure and an unlocking structure. The entire use process can be completed by only turning the handle. The operation is simple and quick, and the use effect is better. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present application.

[0041] See also Figure 1-Figure 7 , an upper limb lifting fixed frame, comprising:

[0042] Binding components 1, two of which are provided and are used to fix the wrists of both hands of the patient respectively;

[0043] Support component 2, two support components 2 are provided, and they correspond one to one with the binding components 1 respectively;

[0044] The adjusting component 3 is disposed between the two supporting components 2 and is used to drive the two binding components 1 to move toward or away from each other;

[0045] in,

[0046] The binding assembly 1 includes a supporting plate 101, and the supporting plate 101 has a concave portion 102 that is concave downward; a fixed box 103 is fixed to the bottom of the supporting plate 101, and the fixed box 103 is rotatably connected to a rotating shaft 104 inside, a winding roller 105 is provided on the rotating shaft 104, and a binding belt 106 is wound around the winding roller 105, and the end of the binding belt 106 passes through the top of the fixed box 103 and passes over the concave portion 102 and is fixed between the end of the supporting plate 101;

[0047] A worm wheel 107 is sleeved on the rotating shaft 104, and a worm 108 meshing with the worm wheel 107 is rotatably connected inside the fixed box 103. The top of the worm 108 penetrates the outer top of the fixed box 103 and is connected to a handle 109.

[0048] In summary, when in use, the entire device can be installed on the detection bed through the support component 2, and then the relative distance between the two binding components 1 can be adjusted through the adjustment component 3, so as to facilitate the use of different patients; in addition, the binding belt 106 in the binding component 1 can cooperate with the recessed portion 102, so that the patient's wrist can be placed in the recessed portion 102 and bound by the binding belt 106, so as to facilitate the fixation of the hand of the stroke patient or the scapulohumeral periarthritis patient, and improve the accuracy of subsequent scanning detection;

[0049] Furthermore, since the winding belt is wound around the winding roller 105, the winding roller 105 can rotate under the action of the rotating shaft 104, so the winding belt can be tied and tightened by rotating the winding roller 105, which is convenient for effectively binding patients with different wrist thicknesses on the one hand, and can be adaptively adjusted according to the patient's comfort level on the other hand, ensuring that the patient's comfort level is maximized during the scanning and detection process;

[0050] Furthermore, the handle 109 is located at the top of the worm 108, and the worm wheel 107 is sleeved on the rotating shaft 104. Therefore, when the handle 109 is turned, the worm 108 rotates, so that the worm wheel 107 is driven, and then the rotating shaft 104 drives the winding roller 105 to rotate, so as to adjust the tightness of the binding belt 106. Since there is a one-way self-locking property between the worm wheel 107 and the worm 108, the worm 108 can drive the worm wheel 107 to rotate, while the worm wheel 107 cannot cause the worm 108 to rotate. Therefore, after the rotation adjustment of the worm 108 is completed, the entire binding belt 106 can be self-locked, and there is no need to additionally set up a locking structure and an unlocking structure. The entire use process can be completed by only turning the handle 109. The operation is simple and quick, and the use effect is better.

[0051] Furthermore, a T-shaped plate 4 is fixed to the bottom of the fixed box 103, and a first telescopic member 5 is connected between the T-shaped plates 4 in the two binding components 1;

[0052] The adjustment assembly 3 includes two parallel connecting plates 301, and a second telescopic member 6 is connected between the two connecting plates 301;

[0053] The first telescopic member 5 and the second telescopic member 6 both include a cover plate 56b and slide plates 56a located on the left and right sides of the cover plate 56b. The left and right sides of the cover plate 56b are provided with slide grooves for the slide plates 56a to slide.

[0054] Furthermore, the tops of the two slide plates 56a in the second telescopic member 6 are both fixed with support plates 302, and a bidirectional screw 303 is rotatably connected between the two support plates 302, and two moving plates 304 are symmetrically threadedly connected on the bidirectional screw 303, and the tops of the two moving plates 304 are respectively fixed to the bottoms of the two slide plates 56a in the first telescopic member 5;

[0055] Therefore, when the bidirectional screw 303 is rotated, the two movable plates 304 move away from or approach each other under the action of the bidirectional threads on the bidirectional screw 303, and the top of the movable plate 304 is fixed to the slide plate 56a in the first telescopic member 5, and the slide plate 56a is fixed to the T-shaped plate 4, thereby facilitating the adjustment of the distance between the two binding components 1; and the first telescopic member 5 and the second telescopic member 6 are set to provide a more stable movement effect, and the top space of the first telescopic member 5 can be used to place a support for the patient's head.

[0056] Furthermore, a guide rod 305 is fixed between the two support plates 302, and the guide rod 305 passes through the two movable plates 304 and is slidably connected with the movable plates 304; the setting of the guide rod 305 can make the movable plate 304 more stable when moving, ensuring the adjustment effect.

[0057] Further, the support assembly 2 includes a shaped plate 201, and a threaded rod 202 is threadedly connected to one side of the shaped plate 201, one end of the threaded rod 202 penetrates the shaped plate 201 and is rotatably connected to a clamping plate 203, and a friction lining 204 is provided on one side of the clamping plate 203 away from the threaded rod 202;

[0058] By rotating the threaded rod 202, the clamping plate 203 drives the friction lining 204 to move, thereby changing the distance between the clamping plate 203 and the inner wall of the molded plate 201, so that the support assembly 2 is clamped on the edge of the inspection bed or other clampable structures, thereby facilitating the fixation of the entire device; and the friction lining 204 is set to provide a certain anti-slip effect to ensure the clamping stability.

[0059] Furthermore, a plurality of insertion holes 7 are provided on one side of the shaped plate 201 away from the threaded rod 202, and a positioning plate 9 is provided on the opposite sides of the two connecting plates 301 through a spring 8, and an insertion rod 10 penetrating the connecting plate 301 is fixed to one end of the positioning plate 9 facing the spring 8, and the insertion rod 10 and the insertion hole 7 cooperate with each other;

[0060] Through the cooperation between the insertion rod 10 and the insertion hole 7, the upper and lower positions of the shaped plate 201 and the connecting plate 301 can be adjusted. When the shaped plate 201 is fixed to the edge of the bed, the upper and lower heights of the connecting plate 301 can be adjusted, thereby adjusting the upper and lower heights of the entire adjustment component 3 and the binding component 1, which is more convenient for use by different patients.

[0061] In addition, it is worth mentioning that in order to ensure the stable movement effect, the vertical sliding connection between the shaped plate 201 and the connecting plate 301 is achieved through a vertical guide groove.
