Description

Technical Field

[0001] The utility model relates to the technical field of medical equipment, in particular to an orthopedic limb trauma first aid fixator. Background Art

[0002] Orthopedic limb trauma refers to injuries to bones or surrounding tissues caused by external forces. Such injuries may include fractures, dislocations, soft tissue injuries or other related problems. Orthopedic limb trauma is usually caused by accidents, sports injuries, falls, car accidents, falls or other external forces. The Orthopedic Limb Trauma First Aid Fixator is a medical device used for first aid fractures, dislocations and other limb injuries. It is designed to provide stable support and fixation to relieve patients' pain, prevent further damage, and promote healing of the injured area.

[0003] After searching, Chinese patent No. CN202020219812.6 discloses an orthopedic limb trauma emergency fixator, including a U-shaped connecting plate, and the end walls of the outer wall of one side of the U-shaped connecting plate are respectively installed with a top plate and a bottom plate, and a handwheel is arranged above the top plate, and the handwheel is installed at the top of the rotating shaft, and the bottom end of the rotating shaft is connected to the bearing through the threaded hole on the top plate, and the bearing is installed in the mounting groove, and the mounting groove is opened at the top center position of the fixed splint.

[0004] The beneficial effects of the above device are: solving the problem that the existing orthopedic limb trauma emergency fixator has a poor fixation effect on patients; the fixation clamping force applied to the patient can be adjusted, thereby improving the comfort of the patient during fixation, and the device has a simple structure, is easy to use, and is highly practical.

[0005] When using the existing orthopedic limb trauma first aid fixator, two plates are generally used to clamp the patient's limb trauma on both sides to achieve compression and hemostasis of the trauma wound and prevent further displacement of the bone from causing secondary injury. However, during the use of the existing device, since the human limb is cylindrical, the two plates are prone to offset during the clamping process, and depending on the location of the patient's limb trauma, clamping in different directions is often required, such as left and right clamping or up and down clamping, and the existing device cannot be adaptively set. To this end, we propose an orthopedic limb trauma first aid fixator. Utility Model Content

DETAILED DESCRIPTION

[0021] Example

[0022] See also Figure 1-4 , the utility model provides a technical solution:

[0023] An orthopedic limb trauma first aid fixator, the surface of a supporting base plate 1 is fixedly connected with a bottom pad 2. When a patient's limb is injured, the patient's limb is placed on the surface of the supporting base plate 1, and the bottom pad 2 can reduce the pressure of direct contact between the supporting base plate 1 and the limb. At the same time, mounting grooves 3 are provided on both side surfaces of the supporting base plate 1, and clamping mechanisms 4 are installed inside the two groups of mounting grooves 3. The limbs placed on the surface of the supporting base plate 1 can be clamped and fixed from both sides by the clamping mechanisms 4, thereby limiting the movement of the injured limbs and further reducing the patient's injuries. At the same time, the clamping mechanism 4 can be rotated and adjusted in the mounting groove 3, and further after the clamping mechanism 4 is adjusted, the clamping mechanism 4 can adjust the spacing relative to the supporting base plate 1, and further the clamping mechanism 4 and the supporting base plate 1 can vertically clamp and fix the patient's injured limb, thereby improving the applicability of the device.

[0024] The clamping mechanism 4 includes a hinge column 401 hingedly installed in the installation groove 3, and the two side surfaces of the hinge column 401 are fixedly connected with a hinge shaft 402, and the hinge shaft 402 is inserted in the supporting base plate 1 in a corresponding manner, so that the hinge column 401 can be rotated in the installation groove 3 to adjust the position of the clamping mechanism 4 on the supporting base plate 1. The side of the supporting base plate 1 is provided with a threaded hole and a limiting bolt 5 is inserted, and the threaded hole is connected to the hinge hole of the hinge shaft 402. By tightening the limiting bolt 5 in the threaded hole and contacting the surface of the hinge shaft 402, the hinge column 401 can be fixed after adjustment.

[0025] The surface of the hinge shaft 402 is fixedly connected with a fixing seat 403. When the fixing seat 403 rotates to a vertical state with the hinge column 401, the injured limb of the patient can be clamped and fixed to the left and right through the clamping mechanism 4. The surface of the fixing seat 403 is provided with a slide groove 404, and a screw rod 405 is inserted inside the slide groove 404. Two groups of sliders 406 are installed on the surface of the screw rod 405. A protrusion A407 is fixedly connected to the surface of one side of the slider 406. A push rod 409 is hinged to the surface of the protrusion A407 through a connecting shaft 408. The other ends of the two groups of push rods 409 are hinged to the protrusion B411 through the connecting shaft 408. The protrusion B411 is fixedly connected to the back of the pressing plate 410. When the screw rod 405 rotates in the slider 406, it controls the slider 406 to slide linearly in the slide groove 404, and the sliding directions of the two groups of sliders 406 are opposite, further controlling the adjustment of the spacing between the two groups of sliders 406. During the adjustment process of the two sets of sliders 406, the two sets of push rods 409 are pushed to rotate, and the two sets of push rods 409 are further controlled to push the pressure plate 410 to slide on the surface of the supporting base plate 1. Through the independent adjustment and control of the two sets of clamping mechanisms 4, the spacing between the two sets of pressure plates 410 can be further adjusted, and the patient's limbs can be clamped and fixed in the horizontal direction with different forces.

[0026] The slider 406 is arranged in an "H" shape and inserted in the slide groove 404, so that when the slider 406 slides linearly on the surface of the screw rod 405, the sliding track of the slider 406 is limited by the slide groove 404, so that the slider 406 can be stably adjusted. At the same time, one end of the screw rod 405 passes through the fixed seat 403 and is connected to a knob 412, which can facilitate the rotation control of the screw rod 405.

[0027] When the fixing seat 403 rotates to a horizontal state with the hinge column 401, the pressing plate 410 is parallel to the surface of the supporting base plate 1. The upper and lower surfaces of the supporting base plate 1 are fixedly connected with the bottom pad 2, which further enables the supporting base plate 1 and the clamping mechanism 4 to clamp and fix the patient's injured limbs up and down, and can also reduce the pressure on the patient's wound. By controlling the spacing adjustment of the two sets of sliders 406 by the screw rod 405, the pressing plate 410 can be controlled to adjust the spacing relative to the surface of the supporting base plate 1, and further clamp and fix the patient's limbs in the vertical direction with different strengths. The patient's limbs can be adjusted in a clamping manner without moving, reducing secondary damage to the patient's limbs.

[0028] Protection pads 413 are fixedly connected to both side surfaces of the pressing plate 410, so that the pressing plate 410 can reduce the pressure injury to the patient's limbs regardless of whether it is clamped left and right or up and down.
