Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of traction tripod, especially based on the reduction traction tripod of hip and intertrochanteric fracture traction. BACKGROUND

[0002] Hip and intertrochanteric fracture traction is an important treatment method for fracture. After the hip and intertrochanteric fracture, the fracture end is prone to displacement due to the particularity of the fracture site and the pulling effect of the muscle. Through traction, the pulling force of the muscle can be resisted, the displacement of the fracture can be corrected, and the normal anatomical position of the fracture can be restored, creating good conditions for the healing of the fracture. At the same time, traction can also relieve pain, reduce local bleeding and swelling, and help the patient's recovery. During the traction process, the weight and direction of the traction need to be adjusted reasonably according to the specific situation of the patient, such as the type of fracture and the degree of displacement, to ensure the effect of traction and treatment safety.

[0003] The reduction traction tripod is indispensable in the treatment of hip and intertrochanteric fracture. It can exert a stable traction force on the affected limb through pulleys and ropes, achieve fracture reduction, overcome muscle tension and make the fracture end return to its original position. It can effectively relieve pain and reduce the stimulation of the fracture end to the nerves. It can properly fix the affected limb to prevent further displacement and facilitate healing. It can facilitate medical care and nursing operations and basic activities of the patient. It can create conditions for rehabilitation and help the formation of callus. Under the guidance of the doctor, rehabilitation training can be carried out to prevent muscle atrophy and joint stiffness and promote the functional recovery of the affected limb, thus ensuring the effectiveness of fracture treatment and the recovery process of the patient.

[0004] However, some existing tripods cannot effectively adjust the angle to adapt to the joint angle of patients in different situations. For example, the connecting parts of some tripods are too rigid and can only switch between a limited number of fixed angles, making it impossible to achieve continuous and subtle angle adjustment. Or the adjustment device is complex and not precise enough, making it difficult for medical staff to accurately match the angle of the tripod to the joint angle required by the patient during actual use, which not only affects the treatment effect but also causes unnecessary pain and discomfort to the patient, prolongs the recovery period, increases medical costs and risks, and thus reduces the practicality and effectiveness of such reduction traction tripods in clinical application. Therefore, the reduction traction tripod based on hip and intertrochanteric fracture traction is proposed to solve the above problems. SUMMARY
