Description

Technical Field

[0001] This utility model belongs to the field of phototherapy device technology, specifically a clamping device with a positioning structure. Background Technology

[0002] Phototherapy is a device that uses light to treat diseases. Based on different wavelengths, light can be divided into ultraviolet, visible, and infrared light. Each type of light has different biological effects, such as promoting growth, sterilization, anti-inflammation, and analgesia. The mechanism of phototherapy is to stimulate human tissues and cells through photochemical and photothermal effects, producing physiological effects, regulating immune function and metabolism, thereby achieving the purpose of treating diseases. Phototherapy has a wide range of applications, including but not limited to delayed fracture healing, arthritis, diabetic foot, shingles, ulcerative colitis, and soft tissue injuries. For these diseases, phototherapy can play an adjunctive therapeutic role, shortening the course of the disease and alleviating patient suffering.

[0003] When using a phototherapy device to treat patients, it is easy for the device to be placed in an inaccurate position, causing the light from the device to be skewed. When the light is skewed, it can affect the therapeutic effect of the phototherapy device, resulting in poor therapeutic results.

[0004] Therefore, this utility model provides a clamping device with a positioning structure. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, at least one technical problem raised in the background art is solved.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A clamping device with a positioning structure, comprising a phototherapy instrument body; a support arm fixedly connected to the side wall of the phototherapy instrument body; multiple positioning rods slidably connected inside the support arm; an adjustment plate fixedly connected to the top of the positioning rods; a drive motor fixedly connected to the bottom of the support arm, and a first adjustment screw fixedly connected to the output end of the drive motor; the first adjustment screw and the adjustment plate being threadedly connected; a push plate fixedly connected to the bottom end of the positioning rods; the adjustment plate and the push plate being arranged parallel to each other; a phototherapy lamp installed on the side wall of the phototherapy instrument body, and the phototherapy lamp being positioned at the top of the corresponding push plate; effectively solving the problem that when using a phototherapy instrument to treat patients, the patient's affected area is easily misplaced, causing the light from the phototherapy instrument to be skewed, which easily affects the treatment effect of the phototherapy instrument, resulting in poor treatment results.

[0007] Preferably, the push plate is internally rotatably connected to a second adjusting screw; the threads on the surface of the second adjusting screw are symmetrically arranged along the center line of the second adjusting screw; the push plate is internally slidably connected to two clamping plates, which are symmetrically arranged along the center line of the second adjusting screw; the second adjusting screw is threadedly connected to the clamping plates; thus, the phototherapy effect on the patient's affected area is better.

[0008] Preferably, an anti-detachment block is fixedly connected to the side wall of the clamping plate; the anti-detachment block is slidably connected to the inside of the push plate; a guide rod is fixedly connected to the inside of the push plate; the anti-detachment block is slidably connected to the guide rod; this makes the clamping plate and the anti-detachment block less prone to tilting during sliding, making the sliding of the clamping plate more stable.

[0009] Preferably, a support pad is fixed to the side wall of the clamping plate; the support pad is symmetrically arranged on the two clamping plates; so that the clamping plate fits more closely with the patient's affected limb, thereby making the clamping plate fix the limb more effectively.

[0010] Preferably, a positioning block is fixedly connected to the side wall of the first adjusting screw; the positioning block is rotatably connected to the inside of the support arm; making the first adjusting screw more stable during rotation.

[0011] Preferably, a plurality of balls are provided between the support arm and the positioning block; the sidewalls of the balls are in contact with the sidewalls of both the support arm and the positioning block; this reduces wear between the support arm and the positioning block.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The clamping device with a positioning structure described in this utility model supports the patient's affected area through a positioning rod and a pushing plate, thereby fixing the patient's affected limb. This allows the patient's affected limb to move closer to or further away from the phototherapy lamp. The structural design achieves the function of fixing the patient's affected limb while restricting the sliding of the pushing plate. This effectively solves the problem that when using a phototherapy device to treat patients, the patient's affected area is often not positioned accurately, leading to skewed light from the phototherapy device. Skewed light can easily affect the treatment effect of the phototherapy device, resulting in poor treatment results.

[0014] 2. The clamping device with a positioning structure described in this utility model, by rotating the second adjusting screw, causes the second adjusting screw to engage with the threaded part of the clamping plate, thereby driving the clamping plate to slide inside the push plate. This structure design enables the clamping plate to support and fix the patient's affected limb, allowing the patient's affected limb to be more accurately aligned with the phototherapy lamp, resulting in better phototherapy effects.

[0021] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0022] Specific implementation examples are given below.

[0023] like Figures 1 to 2As shown in the figure, a clamping device with a positioning structure according to an embodiment of the present invention includes a phototherapy device body 1; a support arm 2 is fixedly connected to the side wall of the phototherapy device body 1; a plurality of positioning rods 3 are slidably connected inside the support arm 2; an adjusting plate 4 is fixedly connected to the top of the positioning rod 3; a drive motor is fixedly connected to the bottom of the support arm 2, and a first adjusting screw 5 is fixedly connected to the output end of the drive motor; the first adjusting screw 5 is threadedly connected to the adjusting plate 4; a push plate 6 is fixedly connected to the bottom end of the positioning rod 3; the adjusting plate 4 and the push plate 6 are arranged parallel to each other; a phototherapy lamp 7 is installed on the side wall of the phototherapy device body 1, and the phototherapy lamp 7 is positioned at the top of the corresponding push plate 6; during operation, when phototherapy treatment is needed for a patient, the patient's affected limb can be placed on the top of the push plate 6, and then controlled by the drive motor. The first adjusting screw 5 is rotated, causing it to engage with the threaded adjustment plate 4. This causes the adjustment plate 4 to rise and fall at the top of the support arm 2. The support arm 2 then restricts the sliding of the positioning rod 3, allowing the adjustment plate 4 to move the push plate 6 up and down. The positioning rod 3 and the push plate 6 support the patient's affected area, thus fixing the affected limb. This allows the patient's affected limb to move closer to or further away from the phototherapy lamp 7. This structural design achieves the function of fixing the patient's affected limb while restricting the sliding of the push plate 6. It effectively solves the problem that when using a phototherapy device to treat patients, the patient's affected area is often not positioned accurately, leading to skewed light from the phototherapy device. Skewed light can affect the treatment effect of the phototherapy device, resulting in poor treatment results.

[0024] The push plate 6 is internally rotatably connected to a second adjusting screw 8; the threads on the surface of the second adjusting screw 8 are symmetrically arranged along the center line of the second adjusting screw 8; two clamping plates 9 are slidably connected internally to the push plate 6, and the clamping plates 9 are symmetrically arranged along the center line of the second adjusting screw 8; the second adjusting screw 8 and the clamping plates 9 are threadedly connected; during operation, when the patient's affected limb is placed on top of the push plate 6, the second adjusting screw 8 can be rotated, so that the threads of the second adjusting screw 8 and the clamping plates 9 engage, causing the clamping plates 9 to slide inside the push plate 6. This structural design enables the clamping plates 9 to support and fix the patient's affected limb, allowing the patient's affected limb to be more accurately aligned with the position of the phototherapy lamp 7, resulting in better phototherapy effects on the patient's affected area.

[0025] An anti-detachment block 10 is fixedly connected to the side wall of the clamping plate 9; the anti-detachment block 10 is slidably connected to the inside of the push plate 6; a guide rod 11 is fixedly connected to the inside of the push plate 6; the anti-detachment block 10 is slidably connected to the guide rod 11; during operation, when the clamping plate 9 slides inside the push plate 6, the push plate 6 restricts the sliding of the clamping plate 9, thus limiting the sliding of the clamping plate 9. At the same time, the guide rod 11 restricts the sliding of the anti-detachment block 10, so that the clamping plate 9 and the anti-detachment block 10 tilt less during the sliding process, making the sliding of the clamping plate 9 more stable.

[0026] A support pad 12 is fixedly attached to the side wall of the clamping plate 9; the support pad 12 is symmetrically arranged on the two clamping plates 9; during operation, when the patient's affected limb is fixed by the clamping plate 9, the support pad 12 on the side wall of the clamping plate 9 can make the clamping plate 9 fit more tightly with the patient's affected limb, thereby making the clamping plate 9 fix the limb better.

[0027] A positioning block 13 is fixedly connected to the side wall of the first adjusting screw 5; the positioning block 13 is rotatably connected to the inside of the support arm 2; during operation, when the first adjusting screw 5 rotates inside the support arm 2, by setting the positioning block 13 on the side wall of the first adjusting screw 5 and restricting the rotation of the positioning block 13 by the support arm 2, the first adjusting screw 5 can be made more stable during rotation.

[0028] Multiple balls 14 are provided between the support arm 2 and the positioning block 13; the sidewalls of the balls 14 are in contact with the sidewalls of both the support arm 2 and the positioning block 13; during operation, when the positioning block 13 rotates inside the support arm 2, the balls 14 between the support arm 2 and the positioning block 13 can change the sliding friction between the support arm 2 and the positioning block 13 into rolling friction, thereby reducing the frictional force between the support arm 2 and the positioning block 13 and reducing wear between them.

[0029] When phototherapy is needed, the patient's affected limb can be placed on top of the push plate 6. The first adjusting screw 5 is then rotated via a drive motor, engaging with the threaded connection of the adjusting screw 5 and the adjusting plate 4. This causes the adjusting plate 4 to rise and fall on top of the support arm 2. The support arm 2 restricts the sliding of the positioning rod 3, allowing the adjusting plate 4 to move the push plate 6 up and down. The positioning rod 3 and the push plate 6 support the patient's affected area, thus fixing the affected limb. This allows the patient's affected limb to move closer to or further away from the phototherapy lamp 7. This design effectively fixes the patient's affected limb and restricts the sliding of the push plate 6, solving the problem of inaccurate patient placement leading to skewed light illumination, which negatively impacts the treatment effect and results in poor therapeutic outcomes.

[0030] After the patient's affected limb is placed on top of the push plate 6, the second adjusting screw 8 can be rotated so that the second adjusting screw 8 engages with the threaded clamping plate 9, causing the clamping plate 9 to slide inside the push plate 6. This structure design enables the clamping plate 9 to support and fix the patient's affected limb, allowing the patient's affected limb to be more accurately aligned with the phototherapy lamp 7, resulting in better phototherapy effects on the patient's affected area.

[0031] When the clamping plate 9 slides inside the push plate 6, the push plate 6 restricts the sliding of the clamping plate 9, thus limiting the sliding of the clamping plate 9. At the same time, the guide rod 11 restricts the sliding of the anti-detachment block 10, so that the clamping plate 9 and the anti-detachment block 10 will tilt less during the sliding process, making the sliding of the clamping plate 9 more stable.

[0032] When the patient's affected limb is fixed by the clamping plate 9, the clamping plate 9 can fit more tightly with the patient's affected limb by setting the support pad 12 on the side wall of the clamping plate 9, thereby making the clamping plate 9 fix the limb better.

[0033] When the first adjusting screw 5 rotates inside the support arm 2, the first adjusting screw 5 can be made more stable during rotation by setting a positioning block 13 on the side wall of the first adjusting screw 5 and restricting the rotation of the positioning block 13 by the support arm 2.

[0034] When the positioning block 13 rotates inside the support arm 2, the ball bearing 14 between the support arm 2 and the positioning block 13 can change the sliding friction between the support arm 2 and the positioning block 13 into rolling friction, which reduces the friction between the support arm 2 and the positioning block 13 and thus reduces the wear between the support arm 2 and the positioning block 13.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments.
