Embodiment Construction

[0011] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings.

[0012] 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 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 degrees, and the best self-locking angle is 15 degrees. Self-locking angle (such as image 3 ) ref...

Abstract

A portable tractor for treating the bone fracture of lower extremity is composed of the external shaped tube with a line of unidirectional stressed teeth having a self-locking angle of 0-45 deg. and 45-80 deg of slide angle on its inner surface and the internal shaped tube in said external one. The handle and foot supporter is fixed to one end of said internal tube and the ratchet unit is fixed to thue other end. A leg supporter is fixed to one end of said external tube. Its advantages are compact structure, easy regulation, and high reliability.

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...
