Description

Technical Field

[0001] The invention relates to the technical field of orthopedic treatment, in particular to an orthopedic splint mounting and fastening device for orthopedics. Background Art

[0002] The reasons why orthopedic splints need to be installed and fastened are mainly divided into the following points: first, to provide stability, limit the movement of the fracture site, prevent further damage, and provide a stable environment for the fracture site so that it can be fully protected during the healing process; second, to promote fracture healing. After the splint is fastened, it can reduce the stimulation of the fracture site to the surrounding tissues; third, to reduce complications, reduce the risk of complications such as infection and bleeding, and facilitate reduction and fixation;

[0003] The existing splints still have some deficiencies. For the fixation of splints, most of them are straight or have a curved surface similar to that of a human body in the middle. When a patient has a fracture, the splint is used for stabilization and then installed and fastened by a device. However, an overly tight splint may cause severe pain to the patient. In severe cases, it may lead to poor blood circulation, aggravate damage to blood vessels and muscles, and even cause skin necrosis and tension blisters. However, if the splint is too loose, it will not be able to maintain effective fixation, affecting the speed of fracture, or causing joint deformity, and finally causing the fracture end to move again. When it moves again, it is necessary to take an X-ray and then use the splint for secondary support again, which will also increase the risk of difficulty in support.

[0004] Secondly, when the splint is fastened to the patient's thigh or arm, if it becomes loose or broken during the process, or if the splint is used for too long, it needs to be replaced. The splint needs to be removed and disinfected after being clamped for a long time. The splint also needs to be removed when the patient is applying medicine or the wound becomes infected. After applying the medicine, the splint should be fixed to the patient's affected area. Summary of the invention

[0009] Furthermore, a plurality of curved panels are vertically arranged on the surface of the movable component, a knob is fixedly connected to the end of the movable component, and a mounting carrier is rotatably connected to the other end of the movable component. A plurality of directional cylinders are relatively arranged on the surface of the mounting carrier, a first spring is arranged inside the directional cylinder, a trapezoidal movable block is arranged on the end of the first spring, the trapezoidal movable block is made of a flexible material, a plurality of triangular notches are relatively opened inside the mounting carrier, and an extrusion block is rotatably connected inside the triangular notch.

[0010] Furthermore, the curved plate rotates inside the diameter of the circular notch.

[0011] Furthermore, an inclined block is arranged inside the triangular notch on the same inclined surface as the extrusion block, a telescopic cylinder is arranged on the inclined block near the surface of the extrusion block, a second spring is arranged inside the telescopic cylinder, and the end of the telescopic cylinder is fixedly connected to the extrusion block.

[0012] Furthermore, the stabilizing mechanism comprises a toothed plate disposed inside the sliding slot, a long rod is disposed inside the toothed plate, and a plurality of groups of pressing blocks are disposed on the surface of the long rod in a linear array.

[0013] Furthermore, a base is provided at the end of another of the limiting carriers, and the base is threadedly connected to the limiting carrier.

[0014] Furthermore, the bottom of the base is provided with diamond-shaped stripes, and the base is made of a flexible material.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] The present invention provides an orthopedic splint installation and fastening device. Through the arrangement of a fastening mechanism, a limiting disc body and a stabilizing mechanism, the splint is firstly fastened when supporting the fracture of a patient. During the fast fastening, the splint has a one-centimeter movable range inside two horizontal and vertical mounting carriers, thereby reducing friction and collision between the fracture ends, maintaining the relative stability of the fracture ends, and avoiding a series of diseases caused by joint stiffness due to excessive fastening. At the same time, the doctor can also timely observe the circulation of the affected part of the affected limb through the movable range of the trapezoidal movable block.

[0017] Furthermore, through the operation of the movable component in the hole, part of the splint is made of semi-flexible material, which has a certain rigidity, but the basic shape of the injured body of the patient is similar to a cylindrical shape close to a cone, and the horizontal clamping of the splint needs to be tilted to adapt the splint. When the splint is fixed inside each mounting carrier, each curved plate will adjust the specific splint tilt angle, and still retain the activity range. When the splint is installed inside the mounting carrier, the splint will be restricted from left and right deviation, so that the splint can only move up and down in the set range, or slide forward and backward by the following manual operation;

[0018] Secondly, by limiting the setting of the disc and the stabilizing mechanism, when the patient's splint needs to be replaced, if the area around the fracture end of the patient is in a sensitive and inflammatory state, removing the splint all at once will cause the fracture end to shift. When one splint is removed, the device still supports the remaining splints, preventing the patient from being subjected to secondary trauma during the recovery period.

[0019] Furthermore, when one of the splints inside the mounting carrier is taken out, the movable rod body moves backwards to bring the splint out a distance, thereby avoiding greater trauma to the patient's fracture when taking it out. At the same time, the toothed plate is pressed down and fixed to both sides of the patient's splint affected part due to the operation of the movable rod body, and real-time support is performed to avoid secondary trauma to the patient's fracture when this part of the splint is taken out. When the patient needs to undergo a dressing change, support can be provided at this part according to the dressing change site to prevent the patient's limbs from shifting left and right due to pain. If a shift occurs, secondary support is required to reduce the frequency of secondary fixation. Secondly, when the patient replaces the splint and changes the dressing, some patients, such as children or the elderly, may have limb tremors due to tension, which may cause the limbs to contract or shake left and right. At this time, the pressing block will fix the affected part while changing the dressing, and then reconnect the splint.

[0020] When the patient does not need to replace the splint or change the dressing, the stabilizing mechanism will move outward and beyond the circumference radius of the knob to support it, preventing the outside from touching the inside of the device and injuring the patient's fracture. When the stabilizing mechanism moves toward the center of the circle, it will support and protect the skin at the splint replacement site and the area where the limbs shake;

[0021] By setting the limiting disc and the limiting carrier, the clamping height of the patient's limbs can be set in advance before the patient's splint is fixed, so as to suit patients of different body shapes and age groups and improve the comfort of the patients.

[0046] The vertical height of the inclined surface of the trapezoidal movable block 236 is between 0.5 and 0.8 centimeters. In order to rotate and better operate the movable component 23, the knob 232 can adjust the tilt angles of the front, middle, rear and end of the splint. The triangular notch 237 is located below the trapezoidal movable block 236, and it will form a certain interval with the extrusion block 238 inside the triangular notch 237.

[0047] The curved plate 231 rotates inside the diameter of the circular slot 24 .

[0048] The curved plate 231 rotates inside the hole 22 with a circular slot 24. When the movable component 23 needs to adjust the tilt angle of the clamp, the knob 232 needs to be rotated. When the position is suitable, the curved plate 231 on the movable component 23 is rotated to make it snap into the inside of the circular slot 24.

[0053] The bottom of the base is provided with diamond-shaped stripes, and the base is made of a flexible material. Specific implementation method;

[0055] When in use, personnel first rotate the limiting disk 1 set inside the limiting carrier 11, or adjust the limiting disk 1 through the ratchet 13 to change the vertical height of the auxiliary hole 15 to adapt to patients of different heights, then extend the patient's affected part into the circumferential center interval generated by the fastening mechanism 2 and the stabilizing mechanism 3, then put on the splint, and adjust the mounting carrier 233 by operating the knob 232 on the arc panel body 21. Then, both sides of the splint will move to the extrusion block 238, and then be in the interval generated by the lower inclined surface of the trapezoidal movable block 236 and the telescopic cylinder 41 to tighten the splint. When the patient's limbs at the splint fixing place move, the trapezoidal movable block 236 is lifted by the splint. When the largest surface of the trapezoidal movable block 236 fits inside the mounting carrier 233, it is the maximum range of motion. When the maximum range of motion is reached, After the range is generated, another group of mutually perpendicular trapezoidal movable blocks 236 will produce a gap. At this time, the first spring 235 inside the directional cylinder 234 will push the splint at this location to make it fit the patient's skin more closely. When the force applied to the trapezoidal movable block 236 in the maximum range becomes smaller, the first spring 235 at this location will push the trapezoidal movable block 236 to reset the splint within a certain range. When the patient needs to replace the splint or apply medicine, the arc panel body 21 is pushed toward the position of the limiting disk body 1. After pushing a certain distance, the movable rod body 25 will drive the long cylindrical tooth body 17 inside the sliding groove 16 to work. At this time, the long cylindrical tooth body 17 drives the tooth plate 31 to move downward. When it fits the affected part of the patient's body, the movable rod body 25 stops moving. At this time, the splint is taken out, replaced, or the affected part of the patient is treated.
