Embodiment Construction

[0012] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0013] figure 1 It is a schematic diagram of the overall structure of a portable lower limb fracture traction frame embodiment. This traction frame mainly comprises exterior pipe 8, is arranged on the interior pipe 7 in exterior pipe, is fixed on the handle 2 of interior pipe one end and foot fixed support 6, and the thigh fixed support 9 that is arranged on exterior pipe 8 one ends. The outer tube and the inner tube are circular tubes, rectangular tubes or triangular tubes. The handle 2 is consolidated with the inner pipe 7, the thigh fixed support 9 is consolidated with the outer pipe 8, and the inner pipe 7 penetrates into the inner hole of the outer pipe 8 and can slide between them. A row of unidirectional force-bearing teeth 16 is arranged on the inner wall of the outer tube 8, and its self-locking angle ranges from 0 to 45 degree...

Abstract

A portable lower limb fracture traction frame relates to a lower limb fracture traction device for orthopedic medical treatment. The traction frame mainly includes an outer tube, an inner tube arranged in the outer tube, a handle fixed at one end of the inner tube, a fixed support for feet, and a fixed support for thighs arranged at one end of the outer tube; There is a row of unidirectional force-bearing teeth on the inner wall. The self-locking angle of the teeth is 0-45 degrees, and the slip angle is 45-80 degrees; The fixedly connected pawl part is made up of a pawl, a pawl rotating shaft, an adjusting screw, a spring and a backguy. The invention can make lower limb fracture patients achieve the purpose of traction and reset without going to the hospital, and has the advantages of compact structure, quick adjustment, reliable traction, convenient carrying, etc., and is especially suitable for use on the battlefield or in catastrophic first aid.

Description

technical field [0001] The invention relates to a lower limb fracture traction frame for orthopedic medical treatment, in particular to a portable lower limb fracture traction frame, which belongs to the technical field of medical auxiliary equipment. Background technique [0002] Lower extremity fracture traction frame (Thomas) is mainly used clinically for non-surgical positioning and treatment of femoral shaft fractures. It uses a special traction bed to fix the patient's lower limbs, and the traction gravity stretches the patient's fractured end through pulleys and steel wires to maintain alignment. After a period of bed rest, the patient gradually achieves the purpose of treatment. The defect of the traction frame used clinically is that the patient needs to stay in bed for a long time, generally needing 8 to 10 weeks, and must be treated in a hospital with a special traction bed for orthopedics, and cannot be used in the field. Contents of the invention [0003] Th...
