Description

Technical Field

[0001] This utility model relates to the field of clamping device technology, specifically a clamping device for a lower limb lifter. Background Technology

[0002] Elevating the lower limbs with a pillow is important. Varicose veins refer to the tortuous and dilated veins caused by blood stasis and weak vein walls. Varicose veins can occur in many parts of the body; for example, hemorrhoids are a type of varicose vein. Clinically, other examples include esophageal and gastric varices, varicocele, and abdominal wall varices. The most common site for varicose veins is the lower limbs. It is important to emphasize that varicose veins are a secondary manifestation of other diseases. Current treatments for varicose veins generally include wearing compression stockings, sclerotherapy, and surgical removal for lower limb varicose veins. For deep vein valve insufficiency, valve repair surgery and endoscopic ligation of perforating veins can be performed. Lower limb varicose veins may also indicate the presence of other diseases, requiring active treatment of the primary disease. If deep venous return is impaired, surgical treatment of superficial veins should be approached with greater caution.

[0003] In the prior art, for example, Chinese Patent Publication No. CN210903801U discloses a lower limb elevation pillow after varicose vein surgery, which includes a base plate, a fixing ring, a mounting plate, and a bracket; the upper end of the base plate is provided with a fixing plate, and the sliding groove of the base plate is slidably connected to the sliding head of the fixing plate; the mounting plate is fixed on the fixing rod of the fixing plate, and the mounting plate and the fixing rod are connected by a mutual sleeve connection.

[0004] The aforementioned patent can fix the lower limbs, but in use, it cannot allow the patient's legs to be fully extended, which may affect local blood circulation. After surgery for varicose veins in the lower limbs, good blood circulation is crucial for wound healing and prevention of complications. If the legs are kept together, blood vessels in certain parts of the legs may be compressed, leading to poor blood flow. Therefore, we propose a clamping device for a lower limb elevator to solve the above problems. Utility Model Content

[0005] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0006] Therefore, the technical solution adopted by this utility model is as follows:

[0007] A clamping device for a lower limb raiser includes a fixed platform, an inclined platform hinged to one side of the fixed platform, a clamping assembly on the surface of the inclined platform, a control assembly on the top of the fixed platform, and a mounting plate fixedly connected to the bottom of the mounting plate. A rotating roller is sleeved in the middle of the mounting plate, and a boss is fixedly connected to one end of the rotating roller near the center of the fixed platform. The boss has a different length between its major and minor axes. The clamping assembly includes two arc-shaped windows on the surface of the inclined platform, each containing a moving seat. A sliding platform is fixedly connected to the top of the moving seat, and mounting brackets are fixedly connected to both sides of the top of the sliding platform. A connecting cylinder is fixedly connected to one side of the mounting bracket near the center of the sliding platform, and a fixed cylinder is sleeved on the surface of the connecting cylinder. A return spring is built into the connecting cylinder, and a clamping ring is fixedly connected to one side of the fixed cylinder near the center of the sliding platform.

[0008] Preferably, the rotating roller is rotatably connected to the mounting plate, the bottom of the boss contacts the fixed platform, and the top of the boss contacts the inclined platform.

[0009] Preferably, a locking knob is installed at the end of the rotating roller away from the center of the fixed platform, and the rotating roller is fixed to the fixed platform by the locking knob.

[0010] Preferably, the two arc-shaped windows are symmetrically distributed along the axis of the inclined platform, and the motion seat is slidably connected to the inner wall of the arc-shaped window.

[0011] Preferably, the inner wall of the arc-shaped window is provided with a guide groove, and guide seats matching the guide groove are fixedly connected to both sides of the motion seat, and the guide seats are slidably connected to the groove wall of the guide groove.

[0012] Preferably, the bottom of the sliding table contacts and is slidably connected to the inclined table, and the connecting cylinder is slidably connected to the inner wall of the fixed table.

[0013] Preferably, one end of the reset spring contacts the bottom of the inner cavity of the connecting cylinder, and the other end of the reset spring contacts the bottom of the inner cavity of the fixed cylinder.

[0014] Preferably, the surface of the connecting cylinder is fitted with a limiting ring to prevent the fixing cylinder from detaching from itself, and a soft pad is fixedly connected to the inner wall of the clamping ring.

[0015] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0016] In this invention, the control component effectively adjusts the height of the tilting platform. A mounting plate connects the rotating roller to the fixed platform, allowing the roller to rotate within the mounting plate. A locking knob at one end of the roller is used for fixation. The major and minor axes of the protrusion at the other end of the rotating roller are of different lengths. Loosening the locking knob and rotating the roller changes the support state of the protrusion between the fixed platform and the tilting platform, raising or lowering the tilting platform. After adjustment, tightening the locking knob locks the height. This design meets the needs of different users for lower limb elevation, allowing the tilting platform to better fit the human body and enhancing the device's applicability. Furthermore, the ingenious arc-shaped window design allows the lower limbs to slide along an arc-shaped path within the device, enabling movements such as spreading and closing. This accommodates slight flexion, extension, separation, and folding of the legs during use, effectively preventing poor blood circulation and further enhancing the device's practicality.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example: Figures 1-5 As shown, this utility model provides a clamping device for a lower limb lifter, including a fixed platform 1. A tilting platform 101 is hinged to one side of the fixed platform 1. A clamping component 3 is provided on the surface of the tilting platform 101. A control component 2 is provided on the top of the fixed platform 1. The control component 2 includes a mounting plate 201. The bottom of the mounting plate 201 is fixedly connected to the fixed platform 1. A rotating roller 202 is sleeved in the middle of the mounting plate 201. The rotating roller 202 is rotatably connected to the mounting plate 201. A locking knob 203 is installed at the end of the rotating roller 202 away from the center of the fixed platform 1. The rotating roller 202 is fixed to the fixed platform 1 through the locking knob 203. A boss 204 is fixedly connected to the end of the rotating roller 202 near the center of the fixed platform 1. The major axis and minor axis of the boss 204 are of different lengths. The bottom of the boss 204 contacts the fixed platform 1, and the top of the boss 204 contacts the tilting platform 101. The rotating roller 202 is connected to the fixed platform 1 through the mounting plate 201 and can rotate in the mounting plate 201. When adjusting the height of the tilting platform 101, loosen the locking knob 203, allowing the rotating roller 202 to rotate freely. Because the major and minor axes of the boss 204 at one end of the rotating roller 202 are different, its support position between the fixed platform 1 and the tilting platform 101 changes as the roller 202 rotates. For example, if the major axis of the boss 204 is gradually raised, it will lift the tilting platform 101, increasing its height; conversely, if the major axis of the boss 204 is gradually lowered, the height of the tilting platform 101 will decrease. After adjusting to the appropriate height, tighten the locking knob 203 to fix the rotating roller 202 to the fixed platform 1, thus locking the height of the tilting platform 101.

[0025] Furthermore, the clamping assembly 3 includes two arc-shaped windows 301, which are formed on the surface of the inclined platform 101. The two arc-shaped windows 301 are symmetrically distributed along the axis of the inclined platform 101. Guide grooves 302 are formed on the inner walls of the arc-shaped windows 301. A motion seat 303 is housed within each arc-shaped window 301 and is slidably connected to the inner wall of the arc-shaped window 301. Guide seats 304, matching the guide grooves 302, are fixedly connected to both sides of the motion seat 303 and are slidably connected to the groove walls of the guide grooves 302. A sliding platform 305 is fixedly connected to the top of the motion seat 303. The bottom of the sliding platform 305 contacts and is slidably connected to the inclined platform 101. Mounting brackets 306 are fixedly connected to both sides of the top of the sliding platform 305. A connecting cylinder 307 is fixedly connected to the side of the mounting bracket 306 near the center of the sliding table 305. A fixing cylinder 308 is sleeved on the surface of the connecting cylinder 307. The connecting cylinder 307 is slidably connected to the inner wall of the fixing table 1. A return spring 309 is built into the connecting cylinder 307. One end of the return spring 309 contacts the bottom of the inner cavity of the connecting cylinder 307, and the other end contacts the bottom of the inner cavity of the fixing cylinder 308. A limiting ring 310 is sleeved on the surface of the connecting cylinder 307 to prevent the fixing cylinder 308 from detaching from itself. A clamping ring 311 is fixedly connected to the side of the fixing cylinder 308 near the center of the sliding table 305. A soft pad 312 is fixedly connected to the inner wall of the clamping ring 311. In the initial state, the return spring 309 is in a natural state or in a certain pre-compressed state. When it is necessary to place the lower limb of the human body into the clamping ring 311, the two clamping rings 311 can be manually pulled outward. At this time, the connecting cylinder 307 slides inside the fixing cylinder 308, compressing the return spring 309. Since the motion seat 303 and the arc-shaped window 301 are slidably connected through the cooperation of the guide seat 304 and the guide groove 302, and the sliding table 305 and the tilting table 101 are also slidably connected, the motion seat 303 can slide smoothly within the arc-shaped window 301 when the clamping ring 311 is pulled, ensuring smooth movement of the entire clamping assembly 3. After the lower limbs of the human body are placed into the clamping ring 311 and the clamping ring 311 is released, the connecting cylinder 307 will return to its original position within the fixed cylinder 308 under the elastic force of the return spring 309, driving the clamping ring 311 to move inward, thereby clamping the lower limbs of the human body. Furthermore, due to the design of the arc-shaped window 301, the lower limbs of the human body can slide along the arc-shaped path within the clamping ring 311, realizing the actions of unfolding and closing.

[0026] Working Principle: When using this device, the control component 2 is mainly used to adjust the height of the tilting platform 101. The rotating roller 202 is connected to the fixed platform 1 via the mounting plate 201 and can rotate within the mounting plate 201. When it is necessary to adjust the height of the tilting platform 101, the locking knob 203 is loosened, at which point the rotating roller 202 can rotate freely. Due to the difference in length between its major and minor axes, the boss 204 at one end of the rotating roller 202 changes its support state between the fixed platform 1 and the tilting platform 101 as the rotating roller 202 rotates. For example, if the major axis of the boss 204 is gradually raised, it will lift the tilting platform 101, thus increasing its height; conversely, if the major axis of the boss 204 is gradually lowered, the height of the tilting platform 101 will decrease. After adjusting to the appropriate height, tighten the locking knob 203 to fix the rotating roller 202 to the fixed platform 1, thereby locking the height of the tilting platform 101. The clamping assembly 3 is used to fix the human lower limb. In the initial state, the return spring 309 is in a natural state or a certain pre-compressed state. When it is necessary to place the human lower limb into the clamping ring 311, the two clamping rings 311 can be manually pulled outward. At this time, the connecting cylinder 307 slides in the fixed cylinder 308, compressing the return spring 309. Since the motion seat 303 and the arc-shaped window 301 are slidably connected through the cooperation of the guide seat 304 and the guide groove 302, and the sliding table 305 and the tilting table 101 are also slidably connected, the motion seat 303 can slide smoothly within the arc-shaped window 301 when the clamping ring 311 is pulled, ensuring smooth movement of the entire clamping assembly 3. After the lower limbs of the human body are placed into the clamping ring 311 and the clamping ring 311 is released, the connecting cylinder 307 will return to its original position within the fixed cylinder 308 under the elastic force of the return spring 309, driving the clamping ring 311 to move inward, thereby clamping the lower limbs of the human body. Furthermore, due to the setting of the arc-shaped window 301, the lower limbs of the human body can slide along the arc-shaped path within the clamping ring 311, realizing the actions of unfolding and closing. During this process, the entire clamping assembly 3 will slide and adjust its position accordingly under the guidance of the arc-shaped window 301 and other structures based on the movements of the lower limbs.

[0027] By controlling the design of the rotating roller 202 and the boss 204 in component 2, the height of the tilting platform 101 can be adjusted more easily to meet the needs of different users for lower limb elevation. This makes the tilting platform 101 more easily fit the different elevation requirements of the human body, improving the applicability of the device. The inner ring wall of the clamping ring 311 is fixedly connected with a soft pad 312, which can provide soft contact when clamping the lower limbs, avoiding excessive pressure or discomfort to the lower limbs and improving the user's comfort. The arc-shaped window 301 design in the clamping component 3 allows the lower limbs to not only be effectively clamped and fixed, but also to open and close within the clamping ring 311. This adapts to some leg activities that may need to be performed during the use of the lower limb elevator, such as slight flexion and extension, opening and closing, etc., preventing poor blood circulation and further improving the practicality of the device.

[0028] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
