Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a limb support device for obstetrics and gynecology. Background Technology

[0002] In obstetrics and gynecology clinical examinations, diagnoses, and surgeries, patients often need to maintain a specific posture for extended periods. To fully expose the examination field and facilitate procedures for medical staff, medical beds or chairs are typically equipped with limb support devices, especially leg supports. These supports are essential basic auxiliary instruments that ensure the smooth progress of the examination and treatment process.

[0003] Currently, most standard obstetric and gynecological leg support devices use fixed rigid brackets or simple semi-enclosed pads. During use, medical staff need to manually adjust the angle and height of the bracket beforehand, and then the patient places their legs on it. However, this traditional static support structure has significant limitations; the shape and enveloping angle of the bracket are fixed and cannot dynamically adapt to changes in leg thickness, leg shape, or gravity during placement.

[0004] Due to the lack of adaptive cushioning and coordinated support, when a patient places their legs on the support, the weight of the legs tends to concentrate on the rigid contact surface of the support. Maintaining this posture for extended periods can easily lead to excessive pressure on the legs, impaired blood circulation, and intense stiffness and discomfort. Furthermore, because it cannot provide a flexible, automatically conforming and clamping support under weight, even slight limb movements due to tension during treatment can easily cause the legs to shift or slip off the support, failing to provide gentle and stable support. This not only reduces the patient's experience but also affects the efficiency and safety of medical staff.

[0005] Therefore, this invention proposes a limb support device for obstetrics and gynecology to address the shortcomings of existing technologies. Summary of the Invention

[0006] To overcome the above deficiencies, the present invention provides a limb support device for obstetrics and gynecology, which aims to improve the problem that some existing limb support devices for obstetrics and gynecology lack adaptive settlement due to the fact that the leg support brackets are mostly static fixed structures.

[0007] The present invention provides a limb support device for obstetrics and gynecology, comprising: a seat and a connecting frame fixedly connected to both sides of the seat; and a leg support mechanism fixedly connected to the outside of the connecting frame.

[0008] The leg support mechanism includes a fixed plate, which is fixedly connected to the outer end of the connecting frame. Hollow columns are fixedly connected to both sides of the fixed plate. An arc-shaped plate is rotatably fitted around the outside of the hollow columns. The arc-shaped plate is curved and conforms to the curve of the human leg to provide clamping and wrapping force inward. A rubber pad is fixedly connected to the top of the arc-shaped plate. Sponges are fixedly connected to both sides of the top of the rubber pad. A telescopic rod is fixedly connected to the top of the fixed plate. The top of the telescopic rod is fixedly connected to the bottom of the rubber pad. A spring is fitted around the outside of the telescopic rod.

[0009] Furthermore, the seat, the connecting frame, and the leg support mechanism are combined through specific mechanical components. The bottom and top ends of the spring abut against the top of the fixed plate and the bottom of the rubber pad, respectively. When compressed, the spring causes the telescopic rod to contract linearly in the vertical direction, while simultaneously pulling the arc-shaped plates on both sides to rotate and flip around the hollow column towards the center, thereby forming an adaptive wrapping structure with weight-bearing linkage clamping.

[0010] Preferably, a buffer assembly is movably connected inside the arc-shaped plate. The buffer assembly includes a connecting column that movably passes through the interior of the arc-shaped plate. A friction pad is fixedly connected to the outer end of the connecting column. The connecting column moves synchronously with the rotation of the arc-shaped plate and transmits the motion trajectory. The friction pad is made of a material with increased friction coefficient and provides mechanical damping during movement.

[0011] Preferably, the hollow column has a buffer plate fixedly connected to its internal array. The friction pad slides in contact with the inner wall of the hollow column and the surface of the buffer plate. Based on the sliding friction fit structure between the friction pad, the buffer plate, and the inner wall of the hollow column, continuous mechanical friction resistance is provided, which forcibly slows down the rotation speed of the arc plate, effectively ensuring a smooth and stable support process and avoiding local pinching discomfort caused by rapid closure.

[0012] Preferably, the bottom of the seat is fixedly connected to a lifting frame, and the bottom of the lifting frame is fixedly connected to a movable base. The lifting frame allows for adjustment of the overall height to adapt to different medical operation scenarios. The movable base is equipped with casters and provides stable bottom support as well as the ability to move between wards and treatment rooms.

[0013] Preferably, the top of the movable base is provided with a sliding groove, and an anti-shaking mechanism is installed above the movable base. The anti-shaking mechanism includes a counterweight. The sliding groove extends along the length direction and provides a linear moving track. The counterweight has a large mass and provides downward gravity to press the movable base.

[0014] Preferably, a guide post is fixedly connected to the bottom of the counterweight, and the guide post is slidably connected inside the slide groove. The guide post slides and limits the counterweight above in the slide groove, ensuring that the counterweight slides smoothly along a predetermined trajectory without deviating during the movement and adjustment process.

[0015] Preferably, a handle is slidably connected to the top of the counterweight, the handle provides a point of force for manual lifting, and connecting rods are fixedly connected to both sides of the bottom of the handle, the connecting rods transmit the lifting action downward and connect to the bottom adsorption component.

[0016] Preferably, the connecting rod passes through and is slidably connected to the interior of the counterweight. A magnetic block is fixedly connected to the bottom end of the connecting rod. The magnetic block is magnetically attracted to the surface of the movable base made of metal. The magnetic block uses magnetic attraction to firmly restrict the counterweight to its current position, counteracting the upper body tilting torque and effectively suppressing the risk of swaying and overturning.

[0017] The present invention has the following beneficial effects: 1. This invention solves the problem that existing obstetric and gynecological support devices lack adaptive wrapping ability and easily cause discomfort to the patient's legs when supporting the legs by setting a linkage clamping leg support mechanism on the outside of the connecting frame, which consists of a fixed plate, hollow column, arc plate, rubber pad, sponge, telescopic rod and spring. It achieves the technical effect of using the downward pressure of the leg to achieve adaptive sinking, and mechanically linking the arc plates with sponge on both sides to flip inward to perform flexible wrapping and lifting, thereby significantly improving the comfort of patients during medical treatment and examination.

[0018] 2. This invention solves the problem of existing technologies lacking damping buffer during leg support clamping mechanism operation, which easily frightens patients or even causes clamping injuries due to excessively fast closing speed. It achieves the technical effect of using the sliding contact between the friction pad, buffer, and inner wall of the hollow column to generate mechanical friction resistance, forcibly slowing down the rotation speed of the arc plate, making the clamping action slow and stable, and effectively ensuring a gentle and stable support process.

[0019] 3. This invention solves the problem in existing technologies where, when a patient changes position or the center of gravity shifts significantly, the supporting equipment chassis is prone to instability, leading to overall swaying or backward tilting safety hazards. This is achieved by opening a sliding groove on the top of the mobile base and installing an anti-shaking mechanism including a counterweight, guide column, handle, connecting rod, and magnetic block. It allows medical staff to quickly slide and adjust the position of the counterweight according to actual changes in the center of gravity, and uses the principle of magnetic attraction to achieve quick and stable locking, thereby effectively balancing the overall center of gravity, offsetting the tipping torque, and strongly suppressing the risk of equipment tipping.

[0022] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0023] Example: Reference Figures 1 to 5 The present invention provides a limb support device for obstetrics and gynecology, which aims to solve the problems in the prior art where obstetrics and gynecology support devices lack adaptive cushioning and wrapping capabilities when supporting the legs, and the support device is prone to shaking or tipping when the user's center of gravity changes.

[0024] like Figure 1 and Figure 2As shown, a lifting frame 2 is fixedly connected to the bottom of the seat 1, and a movable base 6 is fixedly connected to the bottom of the lifting frame 2. The seat 1 provides a sitting posture support and serves as a basic support platform. The lifting frame 2 allows for adjustment of the overall height to adapt to different medical operation scenarios. The movable base 6 is equipped with casters and is responsible for providing stable bottom support and the function of transferring between wards and treatment rooms. Connecting frames 3 are fixedly connected to both sides of the seat 1. The connecting frames 3 extend to both sides and support the leg support structure.

[0025] A leg support mechanism 4 is fixedly connected to the outer side of the connecting frame 3 away from the seat 1. The leg support mechanism 4 provides flexible adaptive support and wraps around the user's legs. The leg support mechanism 4 includes a fixed plate 44, which is fixedly connected to the outer end of the connecting frame 3. The fixed plate 44 acts as the mounting base for the internal linkage clamping structure. Hollow columns 45 are fixedly connected to both sides of the fixed plate 44. The hollow columns 45 provide lateral rotation support points. An arc-shaped plate 43 is rotatably sleeved on the outside of the hollow columns 45. The arc-shaped plate 43 is curved and conforms to the curve of the human leg, thereby providing clamping and wrapping force inward. A rubber pad 41 is fixedly connected to the top of the arc-shaped plate 43. The rubber pad 41 crosses and supports the downward pressure of the leg and provides a non-slip and flexible contact surface. Sponges 42 are fixedly connected to both sides of the top of the rubber pad 41. The sponges 42 are located in the edge area and reduce the local hard pressure when clamping the legs, thereby improving the overall support softness.

[0026] A telescopic rod 46 is fixedly connected to the top of the fixed plate 44. The top of the telescopic rod 46 is fixedly connected to the bottom of the rubber pad 41. When compressed, the telescopic rod 46 retracts linearly in the vertical direction to ensure stable vertical movement and prevent tilting. A spring 47 is sleeved on the outside of the telescopic rod 46. The bottom and top of the spring 47 abut against and support the top of the fixed plate 44 and the bottom of the rubber pad 41, respectively. The spring 47 buffers the pressure when the leg is lowered and accumulates elastic potential energy so that it can be pushed upward to reset when the leg is lifted. When the leg presses down on the rubber pad 41, it causes the telescopic rod 46 and the spring 47 to retract downward and pull the arc-shaped plates 43 with sponges 42 on both sides around the hollow column 45 to rotate and clamp towards the center, thereby achieving the purpose of automatically wrapping and supporting the leg. It also includes a buffer assembly 48. Furthermore, the buffer assembly 48 forms a specific structural cooperation and connection relationship with the aforementioned arc-shaped plates 43 and hollow columns 45. Please refer to the following for details. Figure 2 and Figure 3 The core structure will now be explained in detail.

[0027] The buffer assembly 48 has a connecting post 481 that movably passes through the interior of the arc-shaped plate 43. The connecting post 481 moves synchronously with the rotation of the arc-shaped plate 43 and transmits the motion trajectory. A friction pad 482 is fixedly connected to the connecting post 481 near the outer end of the hollow column 45. The friction pad 482 is made of a material that increases the coefficient of friction and provides mechanical damping during movement. A buffer plate 483 is correspondingly arranged inside the hollow column 45. The buffer plate 483 is arrayed and fixedly connected along the inner wall of the hollow column 45, further increasing the frictional resistance of the contact surface. The friction pad 482 slides in contact with the inner wall of the hollow column 45 and the surface of the buffer plate 483. This sliding frictional contact structure between the friction pad 482 and the buffer plate 483 ensures that when the user presses down on the curved plate 43 to rotate and clamp, continuous frictional damping is generated between the friction pad 482 and the inner wall of the hollow column 45 and the buffer plate 483. This allows the curved plate 43 to slowly and smoothly conform to the leg, effectively ensuring a gentle and stable leg support process and avoiding localized clamping discomfort caused by rapid closure.

[0028] Reference Figure 1 and Figure 4 The top of the movable base 6 is provided with a slide groove 56, which extends along the length direction and provides a linear movement track. An anti-vibration mechanism 5 is installed above the movable base 6. The anti-vibration mechanism 5 includes a counterweight 51, which has a large mass and provides downward gravity to press the movable base 6.

[0029] Reference Figure 4 and Figure 5 A guide post 55 is fixedly connected to the bottom of the counterweight 51. The guide post 55 is slidably connected inside the slide groove 56, and slides and limits its movement within the slide groove 56, supporting the upper counterweight 51. A handle 52 is slidably connected to the top of the counterweight 51, providing a point of force for manual lifting. Connecting rods 53 are fixedly connected to both sides of the bottom of the handle 52, transmitting the lifting action downwards and connecting to the bottom adsorption component. This ensures that the counterweight 51 is quickly and firmly adsorbed and locked in the appropriate position without accidental slippage. The connecting rod 53 passes through and is slidably connected inside the counterweight 51. A magnetic block 54 is fixedly connected to the bottom of the connecting rod 53, magnetically adsorbing onto the surface of the movable base 6 made of metal. The magnetic block 54 uses magnetic attraction to firmly fix the counterweight 51 in the current position.

[0030] The working principle is as follows.

[0031] When the user places their legs on the rubber pad 41, the weight of the legs exerts downward pressure on the rubber pad 41. The rubber pad 41 moves downward under the force, causing the bottom fixed telescopic rod 46 to retract. The spring 47, which is sleeved on the outside of the telescopic rod 46, is simultaneously compressed and deformed to buffer the downward force brought by the moment the legs are lowered. As the rubber pad 41 sinks downward, the arc-shaped plates 43 on both sides, which are rotated and sleeved on the outside of the hollow column 45, are mechanically pulled and rotated inward around the hollow column 45 to clamp. The sponges 42 fixed on both sides of the top of the rubber pad 41 then come close to and gently wrap around the sides of the legs to avoid discomfort caused by hard compression.

[0032] During the inward rotation and closing of the arc plate 43, the connecting column 481 that runs through the inside of the arc plate 43 moves synchronously. The friction pad 482, which is fixedly connected to the outer end of the connecting column 481, undergoes relative displacement inside the hollow column 45. The surface of the friction pad 482 continuously slides in contact with the inner wall of the hollow column 45 and the array of distributed buffer sheets 483. The mechanical friction resistance generated between the friction pad 482 and the buffer sheets 483 effectively slows down the rotation speed of the arc plate 43, allowing the arc plate 43 to slowly and smoothly conform to the leg, effectively avoiding the risk of pinching caused by the instantaneous rapid closing of the arc plate 43 and ensuring a gentle and stable support process.

[0033] When the user lies down or the center of gravity shifts, causing a risk of the chassis tipping over, medical staff pull the top handle 52 of the counterweight 51 upwards. The handle 52 drives the connecting rods 53 fixed on both sides at the bottom to slide upwards inside the counterweight 51. The magnetic block 54 fixed at the bottom of the connecting rod 53 moves upwards and detaches from the surface of the mobile base 6, thus releasing the magnetic attraction and locking state. After the lock is released, medical staff push the counterweight 51 along the sliding groove 56 on the top of the mobile base 6. The guide post 55 fixed at the bottom of the counterweight 51 slides smoothly within the sliding groove 56. After the counterweight 51 slides to a suitable position for the center of gravity to shift, the medical staff releases the handle 52 and causes the connecting rod 53 to drive the magnetic block 54 to re-attach and magnetically attract to the surface of the mobile base 6. The counterweight 51 is firmly fixed in the new position by the principle of magnetic attraction and locking, successfully counteracting the upper body tipping torque and effectively suppressing the risk of shaking and tipping over.

[0034] The buffer component 48 works in conjunction with the leg support mechanism 4 and the anti-shake mechanism 5 features a sliding counterweight design, overcoming the shortcomings of existing technologies such as the lack of adaptive flexible wrapping support and the risk of tipping due to changes in the center of gravity.
