Description

Technical Field

[0001] The invention relates to the technical field of orthopedic equipment, in particular to a traction device for trauma orthopedic emergency treatment. Background Art

[0002] Orthopedics is one of the most common departments in major hospitals. It mainly studies the anatomy, physiology and pathology of the musculoskeletal system, and uses drugs, surgery and physical methods to maintain and develop the normal form and function of this system. When people enter the hospital for emergency treatment due to bone injuries, they need to use traction devices to continuously traction the patients' bones to correct the bones. Bone traction is one of the treatment methods used by orthopedics for fracture reduction, fixation and many other orthopedic diseases. Traction can achieve the treatment goal. The orthopedic traction device is a novel device that uses mechanical transmission to implement traction. It uses the characteristics of combining human physiology with mechanical physics and mechanics science to traction the legs of patients who have difficulty moving their lower limbs due to leg fractures and who maintain a posture for a long time. This is beneficial to the rehabilitation of their lower limbs and avoids the occurrence of joint stiffness, muscle spasms, and even skin necrosis caused by staying still for a long time.

[0003] Orthopedic injuries can occur in both adults and children, and they often occur most often in the leg area. However, most existing traction devices are not convenient for rapid adjustment according to the different body sizes of patients, which delays the emergency treatment time of patients. In addition, when medical staff perform emergency treatment on the patient's legs, due to the different body sizes of patients, when the clamping structure is used to clamp the patient, the clamping is too loose, which affects the limiting effect of the patient's legs. If the clamping is too tight, the blood flow of the patient's legs will be poor, causing discomfort and injury.

[0004] In addition, depending on the patient's leg injury, medical staff often need to flexibly move the patient's legs in multiple directions to a suitable position, and then limit the position to facilitate treatment by medical staff. For example, when treating areas such as the inner side of the leg and the calf, it is inconvenient for medical staff to operate. In addition, when the patient's lower limbs are tractioned and fixed with too rigid traction, there is a risk of excessive traction on the patient's lower limbs, resulting in unnecessary strain, and it cannot satisfy the doctor's perception of the traction force.

[0005] In view of the above problems, it is urgent to carry out innovative design based on the original traction device. Summary of the invention

[0026] Working principle: According to Figure 1 As shown, the bed body 1 is first moved to the vicinity of the patient through the springs with buffer functions on the legs and the universal wheels. In the subsequent movement process, the impact of vibration on the patient's injury is reduced. The patient lies flat on the bed body 1. The medical staff rotates the first threaded rod 2 according to the height of the patient. Through the cooperation of the first sliding rod 3 and the first sliding cylinder 4, the adjustment structure 5 and the gear block gantry frame 6 and other parts are driven to move horizontally on the bed body 1 to the vicinity of the leg position suitable for the height of the patient;

[0027] According to whether the patient has injured both legs or only one leg, the patient's injured leg is placed on the bearing block 1301, and the cover plate 1302 is closed. According to the different thicknesses of the patient's legs, the clamping screw 1303 is rotated to push the movable splint 1304 to move toward the leg, so that the buffer spring 1305 pushes the arc-shaped fitting plate 1306 to fit the patient's leg, thereby limiting the position of the patient's legs of different thicknesses. The setting of the silicone layer improves the comfort of clamping the patient's legs. As the clamping screw 1303 pushes the movable splint 1304 to continue to move downward, the buffer spring 1305 is compressed by force, and the reverse thrust of the buffer spring 1305 pushes the arc-shaped fitting plate 1306 to push closely against the patient, and the movable splint 1304 continues to move downward, so that the arc-shaped fitting plate 1306 cooperates with the bearing block 1301 to apply a limiting force to the patient's leg until it reaches an appropriate force, thereby avoiding excessive clamping of the patient's legs, affecting blood flow and causing discomfort, and also affecting subsequent treatment and rehabilitation after treatment.

[0028] When the patient's legs need to be suspended and traction treated, the medical staff moves the movable plate 7 upward, so that the inclined tooth block surface of the tooth block plate 802 contacts the inclined tooth block surface of the tooth block gantry frame 6, and the tooth block plate 802 is always close to the tooth block of the tooth block gantry frame 6 through the reset spring 804. The movable plate 7 drives the legs to move to the suspension height required for the current treatment stage through the rotating cylinder 9 and the clamping structure 13 and then stops. The tooth block of the tooth block plate 802 and the plane of the tooth block of the tooth block gantry frame 6 contact and mesh with each other, thereby activating the movable plate 7 and the rotating cylinder 9. The parts of the clamping structure 13 are limited to keep the patient's leg support at this height, which is convenient for treatment. During the operation, the medical staff needs to slowly control the movable plate 7 to move to avoid causing damage to the patient's legs too quickly. When it is necessary to control the lifting height, the medical staff pulls the pull rod 803, the reset spring 804 is compressed, the tooth block plate 802 is disengaged from the tooth block gantry frame 6, and the medical staff controls the movable plate 7 and other parts to drive the patient's legs to move slowly down to the suspension height required for the treatment stage;

[0029] Pull up the lifting rod 1002, so that the end of the limiting clamping plate 1003 is disengaged from the gear ring 1004, and the limiting spring 1005 is compressed, and the rotating cylinder 9 is controlled to drive the gear ring 1004 and the clamping structure 13 to rotate to a suitable angle. At this time, the rotating cylinder 9 cooperates with the clamping structure 13 to drive the patient's legs to rotate and lift, and the knees can be vertical, which is convenient for treating the patient's calf area. At the same time, release the lifting rod 1002, and the limiting spring 1005 drives the lifting rod 1002 and the limiting clamping plate 1003 to reset, and the limiting clamping plate 1003 is engaged with the gear ring 1004 again, and the gear ring 1004 and the rotating cylinder 9 are limited. Different heights and angles of different legs of the patient can be adjusted according to emergency needs;

[0030] In addition, according to the distance and strength of traction of the patient's legs during emergency treatment, the adjusting screw 505 is rotated so that the adjusting screw 505 drives the adjusting plate 504 to move to a suitable distance away from the baffle 14. According to the traction needs, the moving distance of the adjusting screw 505 can be controlled so that the adjusting spring 502 is freed from the restraint, and the connecting block 503 and the tooth block gantry frame 6 are pushed to move to the side away from the baffle 14, thereby traction of the patient's legs is achieved. In addition, the traction distance of the device can be flexibly adjusted according to actual needs, thereby enhancing the flexibility of the device.

[0031] When the patient's head needs traction, the patient lies flat on the bed 1, and the head is limited by the restraint belt 19. The motor 16 is controlled to drive the winding roller frame 15 to reel in the wound pull rope 17, so that the pull rope 17 drives the restraint belt 19 to move toward the baffle 14 through the tension meter 18. After moving to a suitable distance, the motor 16 stops, thereby achieving the purpose of traction on the patient's head. The tension meter 18 also makes it easy to observe the traction force. This is the working principle of the traction device for trauma orthopedic emergency treatment.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
